# General Information

3.12.16.2 (01-01-2023) General Information This section gives instructions for resolving errors made by corporate taxpayers and errors made during campus processing. These instructions apply to the Service Center Replacement System (SCRS). This IRM cannot address every possibility while correcting returns or documents. Take taxpayer intent into consideration. Refer issues not addressed in this IRM to the subject matter expert (SME), lead or manager to determine the corrective action. The Service Center Replacement System (SCRS) is a term used to refer to the processing of paper register (error register) documents. While Error Resolution System (ERS) is worked on the computer with Integrated Data Retrieval System (IDRS), SCRS documents are corrected on a paper print, by hand, with a pen. The errors appear on paper error registers. SCRS programs are few as programs continue to be moved to ERS each year. The remaining few are generally received in such small numbers that it is considered too expensive to move them to ERS. Despite the low receipts, these forms are just as important to process correctly as those on ERS. Instructions in specific sections take precedence over general section instructions in case of a conflict. The instructions in this text apply to the following Corporate Income Tax forms: Form and Title Form Title Document (Doc) Code Processing Campus 1120-FSC U.S. Income Tax Return of a Foreign Sales Corporation Note: Form 1120-FSC is used to report the income, gains, losses, deductions, credits, and to figure the income tax liability of a foreign sales corporation. 07 Ogden Submission Processing Campus (OSPC) 1120-ND Return for Nuclear Decommissioning Funds and Certain Persons Note: Form 1120-ND is used to report contributions received, income earned, the administrative expenses of operating the fund, and the tax on modified gross income. 08 Ogden Submission Processing Campus (OSPC) 1120-SF U.S. Income Tax Return for Settlement Funds (Under Section 468B) Note: Form 1120-SF is used to report transfers received, income earned, deductions claimed, distributions made, and to figure the income tax liability of a designated or qualified settlement fund. 06 Ogden Submission Processing Campus (OSPC) Internal Revenue Manual (IRM) 3.12.16 is exempt from the BMF Consistency Guidelines (for example, indicating diamonds) as shown in other sections of IRM 3.12, Error Resolution.

# Organization of Text

3.12.16.2.1 (01-01-2023) Organization of Text The text is organized to find correction procedures quickly and have all necessary procedures in one place. The text is organized as follows: General information on the overall concepts and procedures of the error resolution process. Math error and manual computation criteria and procedural instructions for correcting each section and each field on Form 1120-FSC, Form 1120-ND, and Form 1120-SF error register. Exhibits are displayed on the last pages of the Internal Revenue Manual (IRM) with transcription lines and other frequently used codes with explanations. This text gives sufficient information to correct most error conditions. It may be necessary to refer at times to the instructions in IRM 3.11.16, Corporate Income Tax Returns. If there is a discrepancy between the instructions in IRM 3.11.16 and those in IRM 3.12.16, contact your Headquarters Analyst and continue to follow the instructions in IRM 3.12.16. If there is a conflict between IRM 3.12.16 and another IRM or Job Aid, IRM 3.12.16 takes precedence until the conflict is resolved.

# Taxpayer Advocate Service (TAS)

3.12.16.2.3 (01-01-2025) Taxpayer Advocate Service (TAS) The Taxpayer Advocate Service is an independent organization within the Internal Revenue Service (IRS), led by the National Taxpayer Advocate, that helps taxpayers and protects taxpayer rights. TAS offers free help to taxpayers when a tax problem is causing a financial difficulty, when they've tried and been unable to resolve their issue with the IRS, or when they believe an IRS system, process, or procedure just isn't working as it should. TAS strives to ensure that every taxpayer is treated fairly and knows and understands their rights under the Taxpayer Bill of Rights. TAS has at least one taxpayer advocate office located in every state, the District of Columbia, and Puerto Rico. TAS uses Form 12412, Operations Assistance Request (OAR), to start the OAR process of referring a case to the Taxpayer Services (TS) Division, to affect the resolution of the taxpayer's problem. For more information, refer to IRM 13.1.19, Taxpayer Advocate Service, Taxpayer Advocate Case Procedures, Advocating With Operations Assistance Requests (OARs). Refer taxpayers to TAS when the contact meets TAS criteria or when Form 911, Request for Taxpayer Advocate Service Assistance (and Application for Taxpayer Assistance Order), is attached and steps cannot be taken to resolve the taxpayer's issue the same day. See IRM 21.1.3.18, Taxpayer Advocate Service (TAS) Guidelines. The definition of "same day resolution" is within 24 hours. The following two situations meet the definition of "same day resolution" : The issue can be resolved within 24 hours. The IRS takes steps within 24 hours to resolve the taxpayer's issue. When making a TAS referral, use Form 911, and forward to TAS following your local procedures. For more information, see IRM 13.1.7, Taxpayer Advocate Service (TAS) Case Criteria and IRM 13.1.7.4, Exceptions to Taxpayer Advocate Service Criteria, for information on cases that TAS will no longer accept.

See IRM 25.25.10, Frivolous Return Program, and Exhibit 3.12.16-6, Potential Frivolous Arguments for Examination Review, for a list of recognized frivolous arguments made by businesses. Review the return to decide whether it appears to be a frivolous return. Frivolous Arguments If Then The return meets any of the conditions shown as a frivolous return. See Exhibit 3.12.16-6, Potential Frivolous Arguments for Examination Review. Caution: If the return shows CCC "U" and has a Form 4227 attached with the remarks, "Refer to Exam FRP for audit after processing" , continue to next procedure. Remove the return from the batch and place the return in the locally designated basket for Examination, Frivolous Return Program (FRP) for review. Examination has selected the return as frivolous (e.g., shown by CCC "U" ) and a Form 4227 with the remarks, "Refer to Examination, Frivolous Return Program (FRP) for audit after processing" , but sends the return for processing, Continue processing the return using procedures in IRM 3.12.16.

# IRS Employee Contacts

3.12.16.2.6 (01-01-2024) IRS Employee Contacts The Internal Revenue Service (IRS) Restructuring and Reform Act of 1998 (RRA98), Section 3705(a) provides identification requirements for all IRS employees working on tax-related matters. All IRS employees who communicate by telephone, face-to-face, or any other method of correspondence with taxpayers or their representatives on tax-related matters must give (at a minimum) the following information: Telephone Contact - Their title (e.g., Mr., Mrs., Ms., Miss), last name, and badge identification (ID Card) number. Toll-free employees may also give their location for identification purposes. Treat faxes to taxpayers on tax-related matters as correspondence and include the required information. Face-to-Face Contact - Their title (e.g., Mr., Mrs., Ms., Miss), give as appropriate during the conversation, their last name and badge identification (ID Card) number. Correspondence (sent to the taxpayer and authorized representatives) - A telephone number that taxpayers can call for answers to questions. In addition, manually generated correspondence must have the employee's title (e.g., Mr., Mrs., Ms., Miss), last name, Integrated Data Retrieval System (IDRS) number, and letter system number, which are systemically generated by IDRS. Treat faxes to taxpayers on tax-related matters as correspondence and include the required information. Correspondex letters - Specific employee name and telephone number if the employee initiating the correspondence is in the best position to respond to any questions the taxpayer may have or if the taxpayer is being asked to give more case-related information. If the taxpayer does not need to contact a specific employee, the correspondence needs only an IRS telephone number and standard signature. When a taxpayer requests to speak with a specific employee who previously worked their inquiry or request, or complains about the level of service previously given, make every attempt to resolve the taxpayer's inquiry. If unable to resolve the issue, refer the inquiry using established procedures to the manager. Secretaries, receptionists, or other people who answer the telephone in functional offices need to identify themselves. They should provide their badge identification (ID Card) number only if they are answering telephones which are routinely used to give tax or account information. It is not necessary to repeat the badge identification (ID Card) number on a subsequent contact, when the nature of an employee's work involves multiple contacts with the same taxpayer and the employee has given the taxpayer (either by telephone or in-person) their badge identification (ID Card) number on the first contact.

# Use of Fax for Taxpayer Submissions

3.12.16.2.7 (01-01-2023) Use of Fax for Taxpayer Submissions Taxpayers may send tax return information via fax as part of return perfection even when submitting a signature.

Input TC 599 with Closing Code (cc) 017 on IDRS using Command Code FRM49. Edit an action trail "L118C Sent" (or similar language) in the lower left corner going vertically up the side of the return. Inform the TS SP liaison of all information that is being requested. Give the return back to the TS SP liaison. The TS SP liaison will contact the Taxpayer Advocate to obtain the required information needed to complete the processing of the return. Other Suspense Action - If the return requires other suspense action, then do the following: Initiate the suspense action according to procedures. Inform the TS SP liaison the reason of the action taken. Give the return back to the TS SP liaison. The TS SP liaison will contact the Taxpayer Advocate, who in turn will take the necessary action to complete the processing of the return. Assigning Taxpayer Notice Codes (TPNCs)/Math Error - When a math error is identified, do the following: Assign the applicable TPNC according to procedures. After all TPNCs have been assigned, inform the TS SP liaison of the TPNCs issued. Suspend according to procedures and then give the return to the TS SP liaison. The TS SP liaison will contact the Taxpayer Advocate, who in turn will take the necessary action to complete the processing of the return. When Balance Due/Overpayment Math Error generates do the following: Make a copy of the error register and highlight the Computer-Generated Refund Amount (underprint). Attach the copy to the front of the return with the entity part of the return visible. Enter the amount the taxpayer claimed as the amount they requested to be refunded back into Field 07-I. If Balance Due/Overpayment Math Error loops because the taxpayer made a math error when computing their refund, then do the following: Note: The term "loop" means the register continues to reappear on the next correction cycle until every validity check has been satisfied. Make a copy of the error register and highlight the Computer-Generated Refund Amount (underprint). Attach the copy to the front of the return with the entity part of the return visible. Enter Action Code 1 and assign the correct TPNC. The first time a document in error prints on an error register it is called a "raw" register. Tax examiners will make several corrections to the paper register (error register), trying to correct as many errors as possible. The document and register are then sent back through the Integrated Submission and Remittance Processing (ISRP) system to be transcribed. If the correction resolves the error, the information is transmitted to the Enterprise Computing Center-Martinsburg (ECC-MTB). If all the errors do not clear, the system will generate a subsequent register (known as a "loop" register) showing the errors that are remaining. The title line will tell you if the register is a raw register or a "loop" register and how many times (if any) the register has looped. The term "loop" means the register continues to reappear on the next correction cycle until every validity check has been satisfied. Once return processing is complete, give the return, copy of the error register and Form 12412, Operations Assistance Request (OAR), to the TS SP liaison. Rejects Suspense - Manual refunds that are hand walked by a TS SP liaison that have been suspended should be processed as follows: Follow the specific instruction given by the TS SP liaison in regard to correspondence issues and the assignment of the TPNCs. Refer to applicable paragraphs above.

# Procedures for "In-Care-Of" Instructions

3.12.16.2.13 (01-01-2021) Procedures for "In-Care-Of" Instructions An "in-care-of" name can be identified by the words "in-care-of" or the symbols "c/o" or "%" (percent). Correct "in-care-of" names by researching Integrated Data Retrieval System (IDRS) using Command Code (CC) INOLES. Note: See Integrated Data Retrieval System (IDRS) Command Code Job Aid at: Integrated Data Retrieval System (IDRS) Command Codes Job Aid for more information. Make sure the "in-care-of" name is above the street address. Procedures for "In-Care-Of" If And Then The "in-care-of" name on the return Name control on CC INOLES matches, Delete % (percent) from the name control field. Enter the name control in Field 01-B (Name Control). The "in-care-of" name on the return Name control on CC INOLES does not match, Overlay CC INOLES with CC ENMOD and transmit. There is a pending (PN) transaction changing the c/o name, Delete % (percent) from the name control field. Enter the name control in Field 01-B (Name Control). There is no PN transaction, Input a change to the "in-care-of" name as shown below. Overlay CC ENMOD with CC ENREQ and transmit (Page Up key). Note: CC BNCHG will display. Caution: If CC ENMOD is not present, displays "THE MODULE YOU HAVE REQUESTED IS FOUND AT THE FOLLOWING CAMPUS(S); XXX@ xx," or the ENMOD name control does not match the name control on the return, see the CC MFREQ instructions below. Position the cursor at "CARE-OF-NAME" by tabbing over. Enter the "c/o" name from the return making sure the % (percent) sign is in the first position followed by a space. TAB to "REMARKS" and enter "PER DOC" and transmit (Page Up key). "REQUEST COMPLETED" will display. Delete % from Field 01-B (Name Control) and enter the correct name control in Field 01-B (Name Control).

After "REQUEST COMPLETED" displays, overlay CC MFREQ with CC ENMOD and transmit (Page Up key) to return to the "c/o" name change function. Note: Addresses on extensions should NEVER be changed.

# Criminal Investigation (CI) Referral

3.12.16.2.14 (01-01-2020) Criminal Investigation (CI) Referral Criminal Investigation (CI) investigates potential criminal violations of the Internal Revenue Code (IRC) and related financial crimes. Criminal violations of the IRC include willful attempts to evade or defeat the income tax. Criminal tax violations also include the willful failure to collect or pay over tax and false claims for refunds based on bogus return information. If CI has stamped the return, do not send for further CI action. For returns with refund claims ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡, do the following: Caution: If there is no sign Code and Edit (C&E) made a copy and sent to CI Referral, then see below. Criminal Investigation (CI) Referral Refund Claim Ogden ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ Make a copy of the first two pages of the tax return along with any page of the return that appears suspicious. Attach Form 4227 to the copy. Route the copy to Ogden, Mail Stop 9001, Criminal Investigation (CI). Edit an action trail "Copy to CI" , or "CI Referral" , or similar language in the lower left corner going vertically up the side of the return. Continue processing the return. See IRM 3.12.16.2.9, Refund Returns 45-Day Jeopardy and High Dollar Refunds. Because of the repetitive nature of the ERS/Rejects function, ERS/Rejects Tax Examining Technicians often recognize income tax return data that is outside of the norm for data found on similar returns for each income tax return type. If ERS/Rejects finds return characteristics not meeting Audit Code or Exam referral criteria it deems suspicious, CI is available to review the referral. If a suspicious return is found, and there is no sign Code and Edit (C&E) made a copy and sent to CI Referral, then, do the following: Make a copy of the first two pages of the return along with any page of the return that appears suspicious. Attach Form 4227, Intra-SC Reject or Routing Slip, or other proper routing slip to the copy. Route the copy to Ogden, Mail Stop 9001, Criminal Investigation (CI). Edit an action trail "Copy to CI" , or "CI Referral" , or similar language in the lower left corner going vertically up the side of the return. Continue processing the return. If the return fits other criteria (for example, Frivolous Argument), take proper action.

# Examination (Exam) "Funny Box"

3.12.16.2.15 (01-01-2023) Examination (Exam) "Funny Box" The primary goal in identifying tax returns for examination is to promote the highest degree of voluntary compliance. Examination gives support and helps Submission Processing (SP) with any questionable return found during processing. Exam has many programs and tolerance criteria already found in several IRM sections. SP can refer any questionable return to Exam, unless prohibited by instructions currently found in several IRMs.

# Customer Account Data Engine (CADE) 2

3.12.16.2.17 (01-01-2024) Customer Account Data Engine (CADE) 2 The Customer Account Data Engine (CADE) 2 Program Office in Headquarters is charged with the primary goal of implementing a single, modernized programming solution that gives daily processing of taxpayer accounts. The CADE 2 solution is comprised of several components, to modernize the IRS to a daily processing environment with several Transition States. The Business Master File (BMF) campus cycles are: Campus Cycle: Thursday - Wednesday Master File Processing: Friday - Thursday Notice Review: Saturday - Monday (8+ days) Unpostables: New available Tuesday; Closing Tuesday BMF transaction posting times are: Transactions will be viewable using Corporate Files Online (CFOL) command codes on Saturday following the weekly Master Files processing run on Thursday. Transactions will be viewable as posted transactions using Integrated Data Retrieval System (IDRS) command codes on Monday, following the weekly Master File processing run on Thursday. Note: Implementation of CADE 2 accelerated weekly IDRS analysis. Previously, transactions such as this would have been pending on IDRS and not shown in the CFOL command code displays. Transaction posting dates show a format of YYYYCCDD. YYYY is the year. CC is the posting cycle. Individual Master File (IMF) transactions values for DD are: 01 = Friday 02 = Monday 03 = Tuesday 04 = Wednesday 05 = Thursday Note: BMF cycle posting dates on Command Code (CC) BMFOL will continue to show YYYYCC. YYYY is the year. CC is the posting cycle. BMF posting cycles in TXMOD will show a format of YYYYCCDD. The DD value is 08.

# C/SC Letters

3.12.16.2.18 (02-03-2023) C/SC Letters Below are letters by Headquarters for Submission Processing Campus use in corresponding for items in this IRM. It is expected that tax examiners or their supervisors (or delegates) will have access to and be familiar with the Submission Processing Campus Correspondex for selection of correct letters. Letter 86C, Referring Taxpayer Inquiry/Forms to Another Office - Letter referring taxpayer inquiry and forms to another office. Letter 118C, Corporate Return Incomplete for Processing: Form 1120, Form 1120 Series, Form 1120-S - Letter requesting missing schedules or documents.

# Suppression of Erroneous Balance Due and Return Delinquency Notices - Reject/Suspense Correction

3.12.16.2.19 (01-01-2021) Suppression of Erroneous Balance Due and Return Delinquency Notices - Reject/Suspense Correction For any return received within the specified accounting period which cannot be processed by the Program Completion Date (PCD) as shown in IRM 3.30.123, Processing Timeliness: Cycles, Criteria, and Critical Dates, a Transaction Code (TC) 599 with Closing Code (cc) 018 must be input on Integrated Data Retrieval System (IDRS) using Command Code FRM49. See IRM 3.30.123.2.4, Acceptable Inventory and Aged Criteria for Submission Processing Databases, for more information. This includes block deletes, nullified unpostables and rejects suspense/correction. Input of TC 599 with cc 018 does not need to be completed until three weeks before delinquency checks. However, checks can begin as soon as three weeks after the return's PCD. Note: See Integrated Data Retrieval System (IDRS) Command Code Job Aid at: Integrated Data Retrieval System (IDRS) Command Code Job Aid for more information. Paper registers must have the fact of filing (TC 599) input manually to prevent erroneous notices. Automatic generation of a TC 599 is done only by the Error Resolution System (ERS). Whenever a return or payment must be withdrawn from the workflow, immediate consideration must be given to the possibility that erroneous balance due or return delinquency notices may be issued. This includes block deletes, nullified unpostables, and rejects suspense/correction. If notices would be sent erroneously, Integrated Data Retrieval System (IDRS) action must be input to the correct account by the first person identifying any of the following conditions: If the return is more than ten weeks past the due date, input TC 599 with Closing Code (cc) 018 on IDRS using Command Code FRM49. Any subsequent payment transaction (Document (Doc) Code 017, 018, 019) requires input of Command Code STAUP for six cycles. Note: STAUP is an IDRS Command Code used to delay issuance of service center notices. Annotate the document with "TC 599 cc 018" or "STAUP 6" (or similar language) in the upper left margin of the return. Note: If the document has already been annotated, no further action is required. A Transaction Code (TC) 599 is not necessary when: An Error Resolutions System (ERS) Action Code is entered. A fact of filing (TC 599) is automatically generated on IDRS to prevent delinquency notice issuance; therefore, a TC 599 is not necessary. Returns processed through Integrated Submission and Remittance Processing (ISRP). The payments have already posted on IDRS as a TC 610 (payment received with return) and this satisfies the BMF delinquency check. Note: Integrated Submission and Remittance Processing (ISRP) replaced the previous Distributed Input System (DIS) and Residual Remittance Processing System (RRPS). Returns processed through a Collections Function will show a TC 59X in the middle of the left margin of the return.

# Working Trail

3.12.16.2.20 (01-01-2024) Working Trail It is important to leave a legible "Working Trail" (or "Action Trail" ) using blue ink for those who may work with the return later. Write all Taxpayer Notice Codes (TPNCs) 90 on the front of the return in the upper left corner (or use Form 12648, 90-TPNC). See IRM 3.12.16.3.4.1, Taxpayer Notice Codes (TPNCs), and IRM 3.12.16.4.17, Field 01-M, Taxpayer Notice Code (TPNC), for more information. If corresponding with a non-suspense letter, "X" and write the corrected money amounts to the left of each original point(s) of error. Write money amounts in dollars only or dollars and cents, as applicable. Arrowing is allowed for money amounts when there are no intervening entries between the arrow and the line to which the money is to be entered. Leave a working trail on the return when changes are made to the following items: Employer Identification Number (EIN) Tax Period Received Date Computer Condition Code (CCC) Correspondence Received Date (CRD) Reminder: Circle out incorrect Employer Identification Numbers (EINs), Tax Periods, and Received Dates. When working Reject re-inputs, circle out any previous Action Codes shown on the front of the return, if no longer applicable. When working Rejects, write "Voided" with the date above the DLN in red, when voiding a return.

# Signature

3.12.16.2.21 (01-01-2025) Signature If one of the following returns are mailed between August 28, 2020, and October 31, 2025, and accept a digital signature. Form 1120-FSC Form 1120-ND Form 1120-SF

# Service Center Replacement System (SCRS) - Paper Error Register Information

3.12.16.3 (01-01-2024) Service Center Replacement System (SCRS) - Paper Error Register Information The paper register (error register) is the physical representation of the tax document and any errors that have been identified. It is essentially a printed form of the data input from the document and appears in a standardized format used for nearly every type of SCRS program. Data fields are designated with letters of the alphabet. Each section is designated with the section number. The first part of the error register is the title line. The error register title line identifies the run number, master file, register status, source of the register, type of register, program, form number, format code, date and page number. The error register title line uses a couple of terms "raw" and "loop" . The first time a document in error prints on a register it is called a "raw" register. When a raw register prints, make various corrections to the register, trying to correct as many errors as possible. The document is then sent back through Integrated Submission and Remittance Processing (ISRP) system to be transcribed. If the correction resolves the error, the information is transmitted to the Enterprise Computing Center-Martinsburg (ECC-MTB). If all the errors do not clear, the error register will print again showing the errors that remain. The re-printed register is called a loop register. The title line shows if the register is a raw register or a loop register and how any times the register has looped (correction loop counter). Each error register will have one or more sections of data. The sections will always start with Section 01. Other sections may follow in ascending order but not necessarily in consecutive order, depending upon which sections have data. For example, an error register may show Section 01 through Section 03, Section 05 and Section 07 because Section 04 and Section 06 did not have any data. Each section will have one or more fields. Each field is identified by a letter of the alphabet, starting at A. The fields print consecutively until the end of the section. For example, Section 02 has six fields, starting at Field 02-A (In-Care-Of Name) and going through Field 02-F (ZIP Code). Unlike the sections, the fields print on the error register whether they have data or not. There are two types of fields. They are a variable field and a fixed field. One type of field is a variable field. For example, Field 02-A ("In-Care-Of" Name) is separated from Field 02-B (Foreign Address) by a plus sign (+). The plus sign identifies Field 02-A ("In-Care-Of" Name) as a variable field and is called a breaker; most of the time the breaker will be a plus sign or (less often) a minus sign. A variable field is a field that can have a variable amount of data. For example, Field 02-A ("In-Care-Of" Name) can have up to 35 letters or numbers. If 15 characters are entered in Field 02-A, In-Care-Of Name, the computer will accept the entry. See IRM 3.12.16.5.1, Field 02-A, "In-Care-Of" Name. The other type of field is a fixed field. Unlike the variable field, the fixed field must have a fixed number of spaces. A good example is an Employer Identification Number (EIN). An EIN always has nine digits, so Field 01-C (EIN) will always have nine spaces. Other examples of a fixed field are Field 01-E (Received Date), which will have eight spaces, or Field 01-B (Name Control), which will have four spaces (characters). The computer identifies a fixed field for you by leaving out the breaker. Note: It is important to know the difference between a fixed field and a variable field. Corrections to a fixed field may not have all the required spaces. For example, the name control COE. The name control requires four characters. If only three characters are entered, the computer will not accept the entry and the record will loop. All the spaces in a fixed field must be present. The way to avoid a loop is to enter the data from the return and then account for the blanks left by entering the number of blanks and circling them. A record of the taxpayer's return will appear on the paper register (error register) when the computer has detected an error made by the taxpayer, by the Document Perfection tax examiner or by the Integrated Submission and Remittance Processing (ISRP) operator. Errors appear much differently on paper registers (error registers) than they do in ERS (error codes). The computer shows the errors in two ways: with asterisks and underprints. One way the computer shows an error is with an asterisk (*). The computer will place asterisks in front of the field or fields that are in error. The computer is reporting that something is wrong with this field. Another way the computer shows an error is with an underprint. Instead of an asterisk, the computer is underprinting with what it thinks the correct information (amount, name control, etc.) should be. The Error Correction tax examiner must locate the error and correct the error condition or, in the case of a taxpayer error, issue an explanatory notice to the taxpayer. The tax examiner must manually verify the taxpayer's tax computation in those special instances where the computer is unable to compute tax. Note: Errors appear much differently on paper registers (error registers) than they do in ERS (error codes). Most errors can be found by an asterisk (*) appearing to the immediate left of the Field Designator. Some are special errors that require unique treatment. Errors can occur anywhere in every section except for the Header Section. Research IDRS with correct Command Codes can be used to correct some entity errors.

# General Types of Errors

3.12.16.3.1 (01-01-2026) General Types of Errors There are several types of errors which cause a record to print on the error register. Field errors Section errors Math errors Consistency errors Field errors are shown on the error register by an asterisk printed to the left of the Alpha Field Designator (AFD) in error. This occurs when a field does not have required data or when the contents of the field does not meet the requirements for that field (failed a validity check). See Figure 3.12.16-1, Field Error. Figure 3.12.16-1 This is an example of an error register displaying Section 01 with a Field Error. The error is shown on the error register with an asterisk preceding the field in error. In this example, the field in error is D. There is an arrow pointing to D. Section 01 fields displayed:FIELD ERROR01 ABHEROC001593248*D + - With an arrow pointed at the asteriskE20260415+F + Please click here for the text description of the image. Missing section errors are identified by a (*) single asterisk printed to the left of the section number. A missing section error occurs when a section is missing that the computer identifies as necessary for the correct processing of the return. See Figure 3.12.16-2, Section Error. If the required data or section was not transcribed, enter the data with Action Code 6. If the data cannot be found by checking the return or researching, show the return is unprocessable by entering Action Code 3. Do not try to correct a missing section error by trying to delete the section with Action Code 4. There is no section present (it is missing) and the computer will cause the register to "loop." Figure 3.12.16-2 This is an example of an error register displaying Section 03 with a Section Error. The error is shown on the error register with a single asterisk preceding the section number in error. In this example, the section in error is 03. There is an arrow pointing to * before 03.Section 01 fields displayed:01 ABJACAC002165384D202512E20260415+F +Section 03 fields displayed:There is an arrow pointing to * before 03.A +B +C +D + E + Please click here for the text description of the image. Extraneous errors are a type of section error identified by a single pound sign (#) printed to the left of the section number. An extraneous section is one the computer identifies as not necessary for the complete processing of the return (unnecessary or invalid section). To correct an extraneous section error, do the following: Examine the return and attachments and determine if the section is needed. Delete any unnecessary sections with Action Code 4; or, Enter another section with Action Code 5; or, Correct the section with Action Code 6. Terminus section errors are a type of section error identified by two asterisks (**) printed to the left of the section number. A terminus section is a section that does not fit the prescribed requirements for the given section. See Figure 3.12.16-3, Terminus Error. Several things cause Terminus section errors: Erroneous size of a field or the entire section Non-numeric character in a numeric field Improper formatting of the section Figure 3.12.16-3 This is an example of an error register displaying Section 01, Section 02 and Section 04, with a Terminus Error in Section 04. The error is shown on the error register with two asterisks preceding the section number in error. In this example, the section in error is 04. There is an arrow pointing to ** before 04.Section 01 fields displayed:01 ABCARDC009876521D202512+E20260415+F +Section 02 fields displayed:02 C4341 17 AVE +DBIRMINGHAM +Section 04 fields displayed:Section 04 shows two asterisks preceding the section number indicating a terminus error.There is an arrow pointing to ** before 04.A +B +C +D + E + Please click here for the text description of the image. To correct a terminus section error, do the following: Check that all necessary sections are present. If not, enter the missing sections with Action Code 5 or correct the terminus sections with Action Code 6. Re-enter any field in the terminus section with Action Code 6 if the data is correct as it appears in the section. Delete the section with Action Code 4 if the terminus section is blank and no data is required. Integrated Submission and Remittance Processing (ISRP) section errors are a type of section error identified by a pound sign (#) and an error number printed to the left of the section number. An ISRP section error occurs after ISRP enters the data on the return into the system, the computer performs an automatic check, called a System Edit Run. If an error is detected, the computer prints a pound sign (#) and an error number to the left of the section number, identifying the type of error detected. An explanation of each error number follows. #0 - Normal. #1 - Split screen transmission - The Key Verifier tried to change the check digits, the Key Verifier changed four or more digits of the Taxpayer Identification Number (TIN), or the Original Entry operator (ISRP operator) entered a required section as "missing." #2 - A mixed condition exists, caused by back to back returns with the same data. #3 - Invalid section ending point. #4 - Invalid field length. #5 - A section was entered twice or entered out of sequence by ISRP. This error will be shown on the error register as follows. See Figure 3.12.16-4, ISRP Error. Figure 3.12.16-4 This is an example of an error register displaying Section 01 with an ISRP Error. The ISRP Error Indicator is printed to the left of section number in error. Section 01 fields displayed:ISRP Indicator Error #4 is printed to the left of Section 01.01 ABWHIPC006598314D202512+E20260227+F Please click here for the text description of the image. All fields of an ISRP section error must be examined when this condition exists. For example, if Section 01 of a return is coded, then examine the tax data base section for error to ensure the return data is for the taxpayer whose name control is in Section 01. Even though one or more sections of a record are coded, the validity and consistency checks necessary for the record are made for all sections. If the record is correct as it appears on the error register, then use Action Code 7 to send the record to Good Tape. Corrective action for fields in error must be taken as instructed in the applicable chapter of IRM 3.12.16. Math Errors are shown by the presence of an underprint amount on the error register under the transcribed amount. A math error occurs when the taxpayer gives incorrect information or there is an editing or transcription causing a computed field to be out of balance. See Figure 3.12.16-5, Math Error. Figure 3.12.16-5 This is an example of an error register displaying Section 07 with a Math Error. The Math Error is shown by the presence of an underprint. There is an arrow pointing to the underprint amount.Section 01 shows Fields B (Name Control), C (EIN), D (Tax Period) and E (Received Date). Section 01 fields displayed:01 ABPANTC002587417D202512+E20260415+F +Section 07 shows Fields A (Total Tax), H (Estimated Tax Penalty), I (Balance Due/Overpayment) and an underprint amount under Field I. There is an arrow pointing to the underprint amount. Section 07 fields displayed:07 A 60500+B +C +D+E +F +G +H 2300+I 52800+ I Underprint - 62800+ Please click here for the text description of the image. To correct a math error, compare all entries leading to the underprinted field with the return and correct all transcription errors, editing errors, coding and transfer errors on both the return and the error register. Total Tax Field is computer verified and underprinted only after Total Income and Total Deductions are within tolerance. Therefore, Total Tax may appear valid when either Total Income or Total Deductions are not within tolerance. After making all possible corrections to the error register and examining the return for manual computation requirements, assign the applicable Taxpayer Notice Code (TPNC). Note: The term "loop" means the register continues to reappear on the next correction cycle until every validity check has been satisfied. TPNCs can only be assigned after every validity check has been satisfied. See IRM 3.12.16.3.4.1, Taxpayer Notice Codes (TPNCs). Consistency errors (Relationship errors) involve more than one field on the error register. The error can happen if the input information does not match or is inconsistent with other fields on the error register. An asterisk prints before the involved fields and should be worked together with all involved fields. To correct a consistency error, check all fields marked with an asterisk for coding errors and transcription errors by comparing the data on the register with the related entry on the return. Enter Action Code 6 on the error register to the left of the corresponding section number and correct the field on the error register to agree with the return.

# Action Codes

3.12.16.3.2 (01-01-2022) Action Codes Action Codes are entered on the error register to alert the computer to the type of correction being tried. The table below lists the Action Codes and describes when each Action Code can be used. Action Codes Action Code Type of Correction 0 Action Code (AC) 0 is used when data, as transcribed is correct. (Taxpayer's figures must be verified.) Computer Condition Code (CCC) "Y" may or may not be present. When the "Y" code is required, but has not been entered, enter CCC "Y" and use Action Code 0 on the next correction cycle. Enter Action Code 0 to the left of Section 01. No other corrective action can be used. When Action Code 0 is used, no other AC is valid. 1 Action Code (AC) 1 is used when the taxpayer has made a math error and a TPNC will be sent. Enter Action Code 1 to the left of Section 01. Separate the taxpayer notice codes (TPNCs) from the AC 1 with a hyphen. To send one TPNC, use the following: 1-XX (e.g., 1-05 for TPNC 05). To send more than one TPNC, separate each TPNC with a comma (e.g., 1-05, 10 to send a TPNC 05 and TPNC 10). No other corrective action can be used. When Action Code 1 is used, no other AC is valid. 2 Action Code (AC) 2 is valid for Information Return Processing (IRP) and Reject Register only to delete (D), re-enter (R), or renumber (N) records on the Service Center Control File (SCCF). Enter Action Code 2 to the left of Section 01 (e.g., 2-D). It is only valid when immediately followed by Error/Reject Disposition Codes D (delete), R (re-enter), or N (renumber). No other corrective action can be used. When Action Code 2 is used, no other AC is valid. 3 Action Code (AC) 3 is used to suspend or reject a record as unprocessable. Enter Action Code 3 to the left of Section 01. Prepare and attach Form 3696, Correspondence Action Sheet, or other approved Correspondence Action Sheet, Form 4227, Intra-SC Reject or Routing Slip, or Form 6882, IDRS/Master File Information Request, for campus routing, whichever is applicable. No other corrective action can be used. When Action Code 3 is used, no other AC is valid. 4 Action Code (AC) 4 is used to delete a data section that should not be part of the record (except on a required section, such as Section 01). This code can be used to delete Section 02 through Section 20 (as applicable) of a return. Enter Action Code 4 to the left of the section number being deleted. Action Codes 4, 5 or 6 may be used on the same correction try. 5 Action Code (AC) 5 is used to add a section to the error register. This code can be used to enter Section 02 through Section 20 (as applicable) of a return. Enter Action Code 5 to the left, followed by the section number, the alpha field designators and the data for each field you are adding. Action Code 5 is not valid for sections already present or sections that are not valid for the document. When adding sections, be sure to enter all corrections in the proper sequence. Write in alpha field designators that have amounts transcribed. Action Codes 4, 5 or 6 may be used on the same correction try. 6 Action Code (AC) 6 is used to change information in a field or fields within an existing section. Exception: Do not use AC 6 to add, delete or change the remittance amount or a computer-generated field. Draw a line through incorrect information, but do not line through the field designator or field breaker. Write the correct or missing information directly above the field. Use all uppercase letters when adding or correcting fields or sections. Print clearly and legibly. When adding positive or negative amounts or changing from one to the other, use a comma (,) for positive and a pound sign (#) for negative. When a fixed-length field requires leading blanks, always enter the number of blanks encircled, followed by the corrected data. If the fixed field requires blanks after the data or if the entire field must be blank, you must account for the spaces. Enter Action Code 6 to the left of each section that has fields that need correction. Change any number of fields that need adjustment during one correction cycle. Action Codes 4, 5 or 6 may be used on the same correction try. 7 Action Code (AC) 7 is used to show that a record requires no changes (the data on the error record is correct). It is used to clear certain validity checks. Do not use when underprinted fields are present. Each correction attempt is subject to tests which ensure proper correction procedures are followed. If a correction attempt fails, the record will reappear or "loop" , with an Invalid Correction Attempt "AA" printed on the error register. When Error Reason Code "AA" is present, correct the error register as if no other correction attempt has been made. If no correction is necessary after reviewing return with Error Reason Code "AA" , use Action Code 7 to clear the error register. Enter Action Code 7 to the left of Section 01. No other corrective action can be used. When Action Code 7 is used, no other AC is valid. 9 Action Code (AC) 9 is used for Reject "loop" only. Do not use for raw input or error registers. Note: The first time a document in error prints on a register it is called a "raw" register. Tax examiners will make several corrections to the paper register (error register), trying to correct as many errors as possible. The document and register are then sent back through the Integrated Submission and Remittance Processing (ISRP) system to be transcribed. If the correction resolves the error, the information is transmitted to the Enterprise Computing Center-Martinsburg (ECC-MTB). If all the errors do not clear, the system will generate a subsequent register (known as a "loop" register) showing the errors that are remaining. The title line will tell you if the register is a raw register or a "loop" register and how many times (if any) the register has looped. Use Action Code 9 to re-reject a "loop" register for correspondence or other suspense action. Enter Action Code 9 to the left of Section 01. No other corrective action can be used. When Action Code 9 is used, no other AC is valid.

The name control must have an alpha or numeric in the first position. The remaining positions must be numeric, alpha, ampersand, hyphen or blank. No character may follow a blank. If the correction has less than 4 characters, enter the significant characters and circle the number of remaining positions. The check digit must have blanks in the first two positions and a letter other than "E" , "G" or "M" in the last two positions. When the check digit is present, the computer verifies it with Field 01-C (EIN). Always enter the name control to correct invalid check digits. Take the following action: Field 01-B Criteria If Then There are no errors in the check digits, Enter the name control in Field 01-B (Name Control). The EIN is transcribed correctly, Enter the name control in Field 01-B (Name Control). The name control is invalid or blank, Check for coding errors and transcription errors. Enter the correct data in Field 01-B (Name Control). The name control cannot be determined, Research using Integrated Data Retrieval System (IDRS). All returns and documents input through ISRP must have the name control and tax period validated on the EIF (Entity Index File). Field 01-B (Name Control) or Field 01-D (Tax Period) will underprint if the transcribed field and the EIF name control or tax period don't match. Compare the entries in Field 01-B (Name Control) and Field 01-C (EIN) with the return, to determine the corrective action. EIN and Name Control If Then The EIN on the return and the EIN in Field 01-C (EIN) do not agree, Correct Field 01-C (EIN) to agree with the return. The name control on CC INOLES and Field 01-B (Name Control) agree and it is edited properly, Enter a "1" in Field 01-L (Entity Underprint Code). The name control on the return and Field 01-B (Name Control) do not agree or was transcribed incorrectly, Change Field 01-B (Name Control). The correction does not agree with the name control underprint, Enter a "1" in Field 01-L (Entity Underprint Code). The EIN on the return agrees with the EIN in Field 01-C (EIN), Determine why the name control is underprinted. The name control edited on the return agrees with the name control Field 01-B (Name Control), Compare the name control underprint with the Field 01-B (Name Control). If it is obvious that the underprint was caused by the name being illegible, or coded wrong, change Field 01-B (Name Control) to agree with the name control underprint. If it is not an obvious error, research IDRS using Command Code (CC) INOLES, then use the following Command Codes: NAMEB/NAMEE to research for the EIN on the return. ENMOD to research for the name on the return. BMFOL for the EIN on the return or EIN found on CC ENMOD. The taxpayer checks the name change box, Research Integrated Data Retrieval System (IDRS) using correct Command Codes. If the name change has been completed or is pending, enter correct code in Field 01-L (Entity Underprint Code). See IRM 3.12.16.4.16, Field 01-L, Entity Underprint Code, for more information. If research shows no name change: Reject and route the return to Entity Control following local procedures. Attach Form 4227, Intra-SC Reject or Routing Slip, or other proper routing slip notating why the return is being routed. From the research, determine the correct EIN and name control for the return on the error register. Take the following action: Correction Procedures If Then Another EIN is found for the entity on the return, Change Field 01-C (EIN) to the correct EIN and follow procedures in the first table under (7) above. Multiple EINs are found, Forward the case to Entity Control following local procedures. The EIN on the return is correct and the taxpayer just rearranged the name on the return, Change Field 01-B (Name Control) to agree with the name control on the BMF. The EIN on the return is correct, but the name control on the BMF is not conforming to the acceptable rules for name controlling: Correct Field 01-B (Name Control) to agree with the name control on the BMF. Copy Page 1 of the return, attach any research and forward the case to Entity Control following local procedures. Notate on Form 4227, Intra-SC Reject or Routing Slip, or other proper routing slip what action needs to be taken. If the EIN on return and Field 01-C (EIN) agree but does not agree with the name on the BMF, forward the case (along with any research) to Entity Control following local procedures. See Figure 3.12.16-7, Entity Control Routing.

Correction Procedures If Then Field 01-C (EIN) is invalid, Examine the return and attachments. A correct EIN is found, Enter in Field 01-C (EIN) and on the return. Correct EIN cannot be found, Research using IDRS. The invalid EIN has credits that apply to the return being processed, Move the credits to the correct EIN. Reminder: If you change the EIN and Field 01-B (Name Control) or Field 01-D (Tax Period) is underprinting, then check to see if you must enter Field 01-L (Entity Underprint Code). See IRM 3.12.16.4.16, Field 01-L, Entity Underprint Code, for more information. If the Employer Identification Number (EIN) is changed from the one the taxpayer used, send Letter 3875C, Missing or Incorrect EIN on Return - BMF/EPMF, or Letter 3463C, Missing Information Request to Process Business Returns, as a non-suspense letter to the address on the return. Continue processing the return. Exception: Letter 3463C was updated to include the paragraphs from the Letter 3875C. Letter 3463C may be used when there is more than one correspondence issue (e.g., Incorrect EIN and missing signature). Note: Do not send Letter 3875C when: 1. Three or less digits of the EIN are transposed, different or missing, or 2. The EIN is consecutive numbers (e.g., 12-3456789) or repeating numbers (e.g., 11-1111111), or 3. Command Code (CC) INOLES shows the account has been "merged to" or "merged from" , or 4. The TIN on the return is the taxpayer's Social Security Number (SSN) (check CC INOLEG). Suspense Correction: If there is an indication that Entity Control has assigned an EIN to the return, enter the Entity Assignment Date (found in the lower left corner of Page 1 of the return) in Field 01-G (Correspondence Received Date (CRD)), if it is later than the received date and return due date. If the EIN is changed from the taxpayer's entry and Entity has not already issued Letter 3875C, CP 576, We Assigned an EIN, (or other correct EIN letter or notice), send Letter 3875C as a non-suspense letter to the address on the return. Exception: Letter 3463C, Missing Information Request to Process Business Returns, was updated to include the paragraphs from the Letter 3875C. Letter 3463C may be used when there is more than one correspondence issue (e.g., Incorrect EIN and missing signature). Note: Do not send Letter 3875C when: 1.

# Field 01-D, Tax Period Ending

3.12.16.4.6 (01-01-2026) Field 01-D, Tax Period Ending Field 01-D (Tax Period) is entered in YYYYMM format. The following procedures address invalid tax periods for EARLY FILERS. The tax period is computer-generated as a current calendar year return when ISRP inputs a blank. The tax period cannot be after the current year and month. If the tax period is equal to the year and month of the process date, the tax period will asterisk. For tax periods that are later than or equal to the current month and year: Correction Procedures If Then Later by a year or more, Change to a current fiscal or calendar year. Later by not more than one month, or the taxpayer shows "no income" , Reject the record and attach Form 4227, Intra-SC Reject or Routing Slip, or other proper routing slip notating "Release end of appropriate month." Later by more than one month with no explanation such as "Final" or "no income" , Correspond for confirmation of tax period ending. Later by more than one month and taxpayer shows "Final" on the return, Reduce the tax period to the month before the current processing month. See Figure 3.12.16-8, Tax Period Correction. Figure 3.12.16-8 This is a Tax Period Correction example using a current year Form 1120-FSC (entity part only) and the error register. Form 1120-FSC: To correct the tax period, the tax examiner will circle out the incorrect tax period edited by Code and Edit and edit the correct tax period above the form title (near that area). The tax examiner will reduce the tax period to the month before the current processing month.

# Field 01-D - Statute Control Documents

3.12.16.4.7 (02-27-2025) Field 01-D - Statute Control Documents Any return with a received date that is two years and nine months or more after the Return Due Date is a potential statute control return. A statute control document is filed for a barred period. A barred period is a taxable period on which statutory limitations are placed for allowing refunds, credits, or for assessing additional taxes. A claim for refund must be filed not later than three years from the date the original return was filed or two years from the date the tax was paid, whichever period ends the later. An additional tax assessment must be made within three years from the date the original return was filed. Process non-"G" coded returns as follows: Identify a return for statute control action if the current processing date is two years and nine months, or more, after the original due date or the received date, whichever is later, and has not cleared the Statute Control Group. Reject and route the return using Form 4227, Intra-SC Reject or Routing Slip, or other proper routing slip. Field 01-D (Tax Period) will asterisk for Statute check if the processing date is two years and nine months, or more, after the original due date or the received date, whichever is later and CCC "W" is not present. Process "G" coded returns as follows: Identify a return for statute control action if the current processing date is two years and nine months, or more, after the original due date or the received date, whichever is later, and has not cleared the Statute Control Group. Reject and route the return using Form 4227 or other proper routing slip. Field 01-D (Tax Period) will asterisk if the processing date is two years and nine months, or more, after the original due date or the received date, whichever is later, and CCC "W" is not present. On both non-"G" and "G" coded returns both Field 01-D (Tax Period) and Field 01-F (CCC) will asterisk if the processing date is less than two years after the Return Due Date and a CCC "W" is present. Correct the Tax Period or Computer Condition Code, whichever is incorrect. Statute control returns must be routed to the Statute Control Group daily, or more often, if needed. Exception: Do not route to the Statute Control Group for clearance, enter CCC "W" and continue processing if any of the following conditions are present: Compliance IRC 6020(b) returns. Returns secured by Examination/Collections. Returns with Transaction Code (TC) 59X or Integrated Collection System (ICS) notated on the face of the return. Returns that are substitute returns prepared by Examination (e.g., Substitute For Return (SFR)) in top margin of the return. Returns with a stamp indicating a previous clearance by Statute Control within the last 90 days. Return is a 2021 or prior year original. Due to the COVID-19 pandemic and subsequent Submission Processing (SP) and Accounts Management (AM) site closures, SP and AM developed procedures to bypass AM statute clearance and be processed. In addition, any 2021 or prior year returns previously cleared by AM statute will not be returned by SP to AM to be cleared again if the 90-calendar day statute stamp has expired. If there is an indication that the return has already been cleared through the Statute Control Group within the last 90 days, then enter CCC "W." Code and Edit will enter CCC "W" if the return has been cleared by Statute Control. Note: The May 16, 1986, Federal Register published regulations concerning returns filed with Election under IRC 338(g). Receipt of such returns where the statutory period for assessment has expired should be expeditiously processed as if the statute had not expired. Enter CCC "D" and CCC "R" if the return has a statement indicating that it qualifies for a waiver under Treasury Regulations (Treas. Reg.) 1.338-10(b). In addition, enter CCC "W" to bypass Statute checks, if the current processing date is two years and nine months, or more, after the original due date or the received date, whichever is later. If no indication, reject the record, attach Form 4227 or other proper routing slip to return and route to Statute Control Group. Exception: Due to the COVID-19 pandemic and subsequent Submission Processing (SP) and Accounts Management (AM) site closures, SP and AM developed procedures for BMF 2021 or prior year original delinquent returns to bypass AM statute clearance and be processed. In addition, any 2021 or prior year returns previously cleared by AM statute will not be returned by SP to AM to be cleared again if the 90-calendar day statute stamp has expired. If a rejected document will not reach the Statute Control Group in time for clearance, then photocopy Page 1 of the return, stamp the photocopy "Photocopy-Do not process" and forward it to the Statute Control Group.

# Field 01-D - Tax Period Underprint

3.12.16.4.8 (01-01-2021) Field 01-D - Tax Period Underprint Compare the EIN on the return with Field 01-C (EIN) and apply the following correction procedures when the tax period underprints.

Correction Procedures If Then The EINs do not agree, Change Field 01-C (EIN) to agree with the return. Enter the correct code in Field 01-L (Entity Underprint Code). See IRM 3.12.16.4.16, Field 01-L, Entity Underprint Code, for more information. The EINs agree, Compare the tax period on the return with Field 01-D (Tax Period). If the tax period on the return does not agree with Field 01-D (Tax Period), change Field 01-D (Tax Period) to agree with the return. If the corrected tax period does not agree with the underprint, continue in (2) below. The EIN and tax period on the return agree with Field 01-C (EIN) and Field 01-D (Tax Period) and are transcribed correctly, but do not agree with the underprint, Continue in (2) below. Note: Tax periods reported under the 52-53-week rule may end not more than six days before, and not more than three days after, the end of a month. Be aware of special situations such as 52-53-week filers before changing the tax period. If the tax period on the return is for a short period, "Final" , "Change in Accounting Period" , or "Initial" proceed as follows: Correction Procedures If Then A "Final" return, Enter CCC "F" in Field 01-F (CCC). A "Change of Accounting Period" and Field 01-F (CCC) has a "Y" , Return must be manually verified. Clear the error register with Action Code 0. Enter the correct code in Field 01-L (Entity Underprint Code). See IRM 3.12.16.4.16, Field 01-L, Entity Underprint Code, for more information. It is not a "Final" return or a "Change of Accounting Period" , Review the return for a statement that the taxpayer is complying with: Treasury Regulation (Treas. Reg.) 1.442-1(c) or (d), Treas. Reg. 1.1502-76, Section 444, or Revenue Procedure Rev. Proc. 76-10, Rev. Proc. 82-85, Rev. Proc. 85-58, Rev. Proc. 87-32, Rev. Proc. 92-13, Rev. Proc. 2000-11, Rev. Proc. 2002-37, Rev. Proc. 2006-45, Rev. Proc. 2006-46 or IRC 898(c)(1)(A), IRC 898(c)(2) or IRC 1398. A statement is attached stating that the taxpayer is complying with one of the Treasury Regulations or Rev. Proc. above, except Treasury Regulation 1.442-1(c) or (d) or Rev. Proc. 82-25, Enter CCC "Y" in Field 01-F (CCC). Enter the correct code in Field 01-L (Entity Underprint Code). See IRM 3.12.16.4.16, Field 01-L, Entity Underprint Code, for more information. The taxpayer is complying with Treasury Regulation 1.442-1(c) or (d) or Rev. Proc. 82-25, Enter CCC "Y" in Field 01-F (CCC). Enter the correct code in Field 01-L (Entity Underprint Code). See IRM 3.12.16.4.16, Field 01-L, Entity Underprint Code, for more information. Verify information or research IDRS. The above-mentioned conditions do not apply, Research IDRS using Command Code (CC) ENMOD (or other applicable CC) for the following transaction codes: TC 052 - Reverses TC 053, TC 054 and TC 055. TC 053 - Form 1128, Application to Adopt Change, or Retain a Tax Year, filed and tax period approved for other than Rev. Proc. 87-32. This code applies to all Form 1120 series One of the above transactions is present, and the tax period matches the taxpayer's tax period on the return, Enter a "2" in Field 01-L (Entity Underprint Code). One of the above transactions is present, and the tax period underprint does not match the taxpayer's intended tax period on the return, Route to Entity Control for validation of the transaction code. Attach Form 4227, Intra-SC Reject or Routing Slip, or other proper routing slip with an explanation as to why the document is being sent to Entity Control. None of the transaction codes are present on the entity module, Correspond with the taxpayer for tax period approval. The taxpayer replies with an approved copy of Form 1128, Application To Adopt, Change, or Retain a Tax Year, or Form 8716, Election To Have a Tax Year Other Than a Required Tax Year, Forward to Entity Control so they may update the Fiscal Year Month (FYM) on the Master File. The taxpayer doesn't reply, or does not give tax period approval, Enter CCC "Y" in Field 01-F (CCC). Enter a "2" in Field 01-L (Entity Underprint Code). The taxpayer states this is an "Initial" return; it may be for a full 12 months or a short period. Normally, an "Initial" return will post without matching on FYM. However, if a tax module has been created for the Master File Tax (MFT) that is on the return, it will unpost. Research using IDRS. Research shows no tax modules for MFT 02; this is the first return for the taxpayer, Enter Action Code 3 on the error register. Attach Form 4227 or other proper routing slip and route to Rejects for input of TC 016 (or follow local procedures). Research shows tax modules already created for MFT 02, but no returns posted before the tax period of the return, Enter Action Code 3 on the error register. Attach Form 4227 or other proper routing slip and route to Rejects for input of TC 016 (or follow local procedures). Rejects will input TC 016 to change the FYM to agree with the taxpayer's return. Release the return from the error register one (1) cycle after the TC 016 is input. Move the extension, payments and credits, etc., to the correct tax period, or prepare Form 3465, Adjustment Request, for routing to Accounts Management, to request that the extension, payments and credits, etc., be moved to the correct tax period. Enter a CCC "X" in Field 01-F (CCC) and write a note on the bottom of Form 3465 to remove "X" once credits have been moved. Input a TC 590 with Closing Code (cc) 020 to the module that was created erroneously. Note: Tax periods reported under the 52-53-week rule may end not more than six days before, and not more than three days after, the end of a month. Be aware of special situations such as 52-53-week filers before changing the tax period. If the return covers a full 12 months and the Fiscal Year Month (FYM) in Field 01-D (Tax Period) does not agree with the underprint, research using IDRS. Research using Command Code (CC) BMFOL, CC INOLE or CC ENMOD for the entity and the MFT of the return. Review the transactions posted for the tax periods on the BMF. Correction Procedures If Then Returns filed (TC 150), and the TC 150 are all for the same FYM as the return: Note: There is a tax module for the same FYM as the underprint with extension, payments, credits, etc., posted, that apply to the return being processed. Enter Action Code 3 on the error register. Attach Form 4227 or other proper routing slip and route to Rejects for input of TC 016 (or follow local procedures). Rejects will input TC 016 to change the FYM on the BMF to agree with the return. Release the return from the error register one (1) cycle after the TC 016 is input. Enter a "2" in Field 01-L (Entity Underprint Code). Move the extension, payments, and credits, etc., to the correct tax period, or prepare Form 3465, Adjustment Request, for routing to Accounts Management, request that the extension, payments, and credits, etc., be moved to the correct tax period. Enter a CCC "X" in Field 01-F (CCC) and write a note on the bottom of Form 3465 to remove "X" once credits have been moved. Input a TC 590 with Closing Code (cc) 020 to the module that was created erroneously. Note: Tax periods reported under the 52-53 week rule may end not more than six days before, and not more than three days after, the end of a month. Be aware of special situations such as 52-53 week filers before changing the tax period. Initiate correspondence with the taxpayer, requesting a clarification of the accounting period, if the posted TC 150 are for several tax periods (no pattern), or posted TC 150 are all for the same FYM but disagree with the tax period of the return. Telephone contact may be used. The table below provides procedures for processing correspondence. If Then The taxpayer replies and identifies the correct tax period and it agrees with the return tax period, Enter Action Code 3 on the error register. Attach Form 4227 or other proper routing slip and route to Rejects for input of TC 016 (or follow local procedures). Rejects will input TC 016 to change the FYM on the BMF to agree with the return. Release the return from the error register one (1) cycle after the TC 016 is input. Enter a "2" in Field 01-L (Entity Underprint Code). Move the extension, payments, and credits, etc., to the correct tax period, or prepare Form 3465, Adjustment Request, for routing to Accounts Management, request that the extension, payments, and credits, etc., be moved to the correct tax period. Enter a CCC "X" in Field 01-F (CCC) and write a note on the bottom of Form 3465 to remove "X" once credits have been moved. Input a TC 590 with Closing Code (cc) 020 to the module that was created erroneously. The taxpayer replies and identifies that the tax period on the return is incorrect and gives the correct period that does not agree with the underprint, Change Field 01-D (Tax Period) and follow procedures directly above. No reply and the last tax period with a TC 150 is 12 months or more before the return tax period, Enter Action Code 3 on the error register. Attach Form 4227 or other proper routing slip and route to Rejects for input of TC 016 (or follow local procedures). Rejects will input TC 016 on IDRS CC ENMOD using CC BNCHG. Input TC 474 on CC REQ77 (using one (1) cycle delay) for the year and month before the beginning month of the tax period on the return being processed. Hold for one week. Correct the return and the error register one (1) cycle after the input of TC 474. When pending (PN) TC 016 generates on CC ENMOD, enter a "2" in Field 01-L (Entity Underprint Code) for "Initial" returns. No reply to correspondence and the last tax period with a TC 150 is less than 12 months before the return tax period, Enter CCC "Y" in Field 01-F (CCC). Enter a "2" in Field 01-L (Entity Underprint Code).

In January 2014, the Taxpayer Notice Code (TPNC) 90 Math Error (ME) Code literals/language were programmed into the OnLine Notice Review (OLNR) Retype Application for Notice Review (NR). This addition will eliminate the need for the NR tax examiner to manually type the notice literal and reduce potential copying and typing incorrect paragraphs and messages in the notices. Notice Review can copy and paste non-programmed TPNC 90 literals in the notice. For an updated listing of the non-programmed TPNC 90 literals, see TPNC 90 Literals - Copy and Paste Job Aid on Servicewide Electronic Research Program (SERP) at TPNC 90 Literals - Copy and Paste Job Aid. TPNC 90 is an error explanation "fill-in" that is used if the standard TPNCs do not adequately describe an error condition or correction(s) made or when more than three or more notice codes are necessary. Ten blank lines (70 characters per line) are available to give pertinent information to the taxpayer. Write the TPNC 90 on the front of the return in the upper left corner or use Form 12648, 90-TPNC. When sending a TPNC 90, do the following: Write on the return "TPNC 90 - ###" (or similar language) or use Form 12648, 90-TPNC, for OnLine Notice Review. Notate "TPNC 90" (or similar language) and the date on Form 1332, Block and Selection Record, or Form 2275, Records Request, Charge and Recharge. Place the return in the TPNC 90 designated area (basket/tub). If there is not an applicable TPNC 90, then do the following: Attach the applicable TPNC 90 slip of paper to the front of the return, after completing applicable fields, or use Form 12648, 90-TPNC, with the TPNC or narrative to be sent. Notate "TPNC 90" (or similar language) and the date on Form 1332, Block and Selection Record, or Form 2275, Records Request, Charge and Recharge.

# Field 02-F, ZIP Code

3.12.16.5.6 (01-01-2023) Field 02-F, ZIP Code Field 02-F is the entity ZIP information (12 positions). Correction Procedures: Correct all misplaced entries, coding errors and transcription errors. If a valid ZIP Code is unavailable from the return or attachments, see Exhibit 3.12.16-10, U.S. Possessions ZIP Codes, for a valid ZIP Code. See Document 7475, State and Address Abbreviations, Major City Codes (MCCs), ZIP Codes and Countries. All ZIP Codes are standardized at Martinsburg Computing Center (MCC) before the return posts to the Master File. A program called "Finalist" matches the taxpayers Street Address and City Address to the ZIP Code on the return with the latest ZIP Code updates received from the U.S. Postal Service (USPS). If the ZIP Code is correct, the program standardizes the ZIP Code to a 12-digit ZIP Code and passes the record (return) on to the Master File for posting to the taxpayer's account. If the ZIP Code is incorrect, but there is a match to the taxpayer's Street and City address, the program corrects and standardizes the ZIP Code, and passes the record (return) on to the Master File for posting to the taxpayer's account. If the ZIP Code is incomplete (partial) on the return, but it has a Street and City address, no research is necessary, take the following action: Enter the Major State Code that includes the last two digits of "01" . See Document 7475, State and Address Abbreviations, Major City Codes (MCCs), ZIP Codes and Countries. If there is a match by the program, the ZIP Code is standardized at MCC for posting to the Master File. If there is no match by the program, MCC passes the return on to the Master File for posting, but an Error Listing is generated and sent to the campus for correction. If the ZIP Code is incomplete on the return and the Street or City address is incomplete or missing, then research is needed for the complete address. Follow local procedures for research. If only the first three digits of the ZIP Code can be determined, enter "01" for the fourth and fifth digits. If the first three digits of the ZIP Code cannot be determined, see Document 7475, State and Address Abbreviations, Major City Codes (MCCs), ZIP Codes and Countries. The U.S. Postal Service (USPS) created new address requirements for Army Post Office (APO), Diplomatic Post Office (DPO), and Fleet Post Office (FPO) addresses. If the old address appears (e.g., APO New York, NY 091XX), convert to the new state code abbreviation based on the ZIP Code (e.g., the previous example would be converted to APO AE 091XX). APO/DPO/FPO addresses are considered domestic addresses. Refer to conversion table below: APO/DPO/FPO Criteria Address State Code Abbreviation ZIP Code APO/DPO/FPO AA 340XX APO/DPO/FPO AE 090XX - 098XX APO/DPO/FPO AP 962XX - 966XX IMPORTANT: Field 02-F must be blank if the address is foreign.

3.12.16.8.10.1 (01-01-2026) Refund Returns Field 07-I (Balance Due/Overpayment) will asterisk as a precautionary flag whenever there is a refund for review and manual verification. Returns will not be forced to the error register solely because of the presence of a refund amount in Field 07-I. Field 07-I will asterisk on initial input and on all subsequent loops. Once all true error conditions are corrected, Field 07-I will automatically clear. Field 07-I will also asterisk, until Reserve Code "1" is entered if the overpayment amount minus credit elect per computer (not taxpayer's amount) ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ Check for coding errors and transcription errors. If the refund ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡, and the return has been in processing for less than 20 days from the received date or return due date (whichever is later), verify that the transcribed refund amount is the same as the return refund line. If the amounts are the same, then input "1" in Field 03-E (Reserve Code) to allow the systemic refund to be generated. Caution: If the return has been in processing for 20 days or more from the received date or return due date (whichever is later), reject and flag the return for issuance of a manual refund if the refund has not been issued. Once the manual refund has been issued, enter a "1" in Field 03-E (Reserve Code). If the refund ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ and the return has been in processing for 20 days or more from the received or return due date (whichever is later), reject and flag the return for issuance of a manual refund if the refund has not been issued. Once the manual refund has been issued, enter a "1" in Field 03-E (Reserve Code). Caution: Because of the tendency for SCRS returns to "loop" over and over, it is up to the campus to determine if they want to continue to process SCRS refund returns ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ Reject and flag the return for issuance of a manual refund if the refund ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ and the refund has not been manually refunded. Once the manual refund has been issued, enter a "1" in Field 03-E (Reserve Code). Refund returns have a 45-day interest free period (180 days for any overpayment resulting from tax deducted and withheld under Chapter 3 or Chapter 4). The interest free period is the 45-calendar day span of time between the return due date, received date or processable date (whichever is later) and the actual date of the refund check. The due date of the return is the 15th day of the fourth month after the end of the tax year. Example: The due date for a 2025 calendar year return is April 15, 2026. Note: Section 2006(a) of the Surface Transportation and Veterans Health Care Choice Improvement Act of 2015, Public Law (P.L.) 114-41, changed the return due date for C corporations and is effective for taxable years beginning after December 31, 2015. The federal income tax return for the Form 1120 series of returns (except Form 1120-C, Form 1120-S and Form 1120-IC-DISC) are due on or before the 15th day of the fourth month following the close of the C corporation's tax year, with several exceptions, including: The income tax return of a C corporation that ends its tax year in June is still due on or before the 15th day of the third month following the close of the fiscal year for tax years beginning after December 31, 2015, and before January 1, 2026. The return is in jeopardy when 20 or more days have elapsed since the received date or the return due date. If it is apparent that the 45-day interest free period is in jeopardy or that the interest free period has expired on a return with a refund ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡, then bring the matter to the immediate attention of your supervisor and follow local procedures. Interest is never payable on "No Replies." If a date is correctly present in Field 01-G (CRD), interest is payable 45 days from the Correspondence Received Date. If a manual refund must be issued, reject the record with Action Code 3 and flag the return for expedite issuance of the manual refund. Input TC 599 with Closing Code (cc) 017 on IDRS using Command Code FRM49 to prevent delinquency notice from generating when a refund return is pulled for a manual refund.

If the taxpayer's correspondence addresses issues not related to the return being processed, photocopy the request and forward to the correct area. If there is an Entity Assignment Date and a correspondence received date, enter the latest date in Field 01-G (CRD).

# Manual Computations

3.12.16.19 (01-01-2020) Manual Computations The computer will accurately compute the tax on most returns if they have been properly filled out, edited, and transcribed. It is imperative that tax examiners be able to identify a return requiring manual computation. If the tax examiner doesn't identify such returns, incorrect settlement with the taxpayer will result. A "manual computation" return requires an Action Code 0 or an entry of corrected tax in the Field 07-Z (Manually Corrected Total Tax) and Action Code 1. Note: These corrections override the computer determination of what is the correct Total Income Tax. You may, therefore, never use this code unless and until the transcribed Total Income Tax printed on the error register agrees with the correct Total Income Tax ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ as you have computed it, and all other transcription is correct. Code and Edit is instructed to enter CCC "Y" for returns that have a "change of accounting period" on a short period return. Other returns will print out on the register because of the underprint in the Total Tax Field. Therefore, you must examine the entire return to determine if it requires manual verification or not. Before performing the computation, everything must be present and correct on the register. Returns that require manual computations are more frequent in years when the tax rates change as they did in 1982, 1983, 1984 and 1993 (corporations with $1 million or more in Taxable Income), tax periods straddling July 1, 1987, and Control Group Corporations with $100,000 or more in Taxable Income with tax periods 198707-198811. Returns that are 52-53-week filers and those that are "Initial" or "Final" short year need to be manually computed only when they straddle two different tax rates. For these returns as well as "change of accounting period" returns, the tax must be computed on the actual days or months used.

# Rule of Two

3.12.16.19.1 (01-01-2018) Rule of Two Under normal circumstances, the computer and the taxpayer or the taxpayer and the tax examiner agree on the computation of the tax. This satisfies the Rule of Two. On most returns with true math errors, the computer and the tax examiner will agree on the computation of the tax. This satisfies the Rule of Two. On a manually computed return with a true math error, the Rule of Two is not satisfied until two tax examiners arrive at the same tax computation.

# Specifically Quoted Sections

3.12.16.19.2 (01-01-2018) Specifically Quoted Sections When a taxpayer has quoted specific sections of the Internal Revenue Code, and the tax computation is mathematically verified as correct, it is preferable to accept this computation than to send a taxpayer a notice. If the reference is questionable, refer the record to the manager for research of the Internal Revenue Code. A large (erroneous) refund or a large increase in tax could create bad taxpayer relations.

# Correction Procedures

3.12.16.19.3 (01-01-2025) Correction Procedures Compute the tax using the corporate manual computation requirements. Use the credits and additional taxes as you normally would. Compute tax from the Taxable Income through Total Tax fields. If there is no error, use Action Code 0. If there is an error: Enter the correct tax in Field 07-Z (Manually Corrected Total Tax). Attach your tape with two stamps on it or two individual tapes (this applies the Rule of Two). When verifying the 5% (percent) or 3% surcharge, a tape is not required. Correct the document from the point of error. Exception: The Total Tax Field must always reflect the taxpayer's figure. Change only the fields on the register that are being changed to achieve the figure entered in Field 07-Z (Manually Corrected Total Tax), an adjustment in the credits used before the Total Tax Field. On "loop" , if there are no transcription errors, enter Action Code 1 and TPNC 05. If the correct tax ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ of the underprint in the Total Tax Field, use the computer's figures and enter Action Code 1 and TPNC 05, except with CCC "Y" returns. On "Y" coded returns, Field 07-Z (Manually Corrected Total Tax) must always be used when the taxpayer has made an error.

# Returns Requiring Manual Computation

# Annualization Computations

3.12.16.20 (01-01-2020) Annualization Computations "Y" Coded, "Change of Accounting Period" returns cover a period of less than 12 months or 52-53 weeks. These returns are not "Initial" or "Final" returns. Proof of permission of the change must be attached, such as one of the following: Form 1128, Application to Adopt Change, or Retain a Tax Year, with approval space signed. Copy of grant letter giving permission to change its taxable year. Statement that the taxpayer is changing the accounting period, including a list of citations to the relevant authorities relied upon by the taxpayer for making the requested change. Note: If Rev. Proc. 2006-46, Rev. Proc. 2006-45, or Treasury Regulations 1.442-1(c) is stated, Audit Code "3" must be present (Form 1120-FSC, Form 1120-ND and Form 1120-SF). If proof of permission is not attached, initiate research of the Form 1128 file kept by Entity Control. If proof of permission is not attached and not found in Entity, correspond with taxpayer for reason for short period. CCC "Y" must be present on all returns that have a "Change of Accounting Period" to update the tax period on the Master File. A subsidiary before its inclusion in a consolidated return (IRC 1502-76) is "Y" coded but not annualized.

# Optional Method of Annualization

3.12.16.20.1 (01-01-2018) Optional Method of Annualization IRC 443 requires a taxpayer to file a short period return if it changes its accounting period. In completing the short period return, the taxable income and corresponding tax liability for the short period must be annualized under IRC 443(b)(1). Under the IRC 443(b)(1) method, the modified taxable income for the short period is annualized by multiplying the short period income by 12 and then dividing that amount by the number of months in the short period. Next, applicable tax rates are used to compute an annualized tax liability. The annualized tax liability is then multiplied by a fraction, the numerator of which is the number of months in the short period and the denominator of which is 12. The result is the short period tax liability under IRC 443(b)(1). Note: See the Example in the table below. An alternate short period tax liability may also be computed under IRC 443(b)(2) if the taxpayer timely applies to use that alternate method of calculation and if the alternate method results in less tax liability. The short period tax liability determined under IRC 443(b)(2) is the greater of the amount determined under IRC 443(b)(2)(A)(i) or the amount determined under IRC 443(b)(2)(A)(ii). The amount determined under IRC 443(b)(2)(A)(i) is based on the modified taxable income from the 12-month period beginning on the first day of the short period. First, applicable tax rates are used to compute the tax liability for the 12-month period. Second, the short period tax liability is determined by multiplying the tax liability for the 12-month period by a fraction, the numerator of which is the income for the short period and the denominator of which is the modified taxable income for the 12-month period. Note: See the Example in the table below. The amount determined under IRC 443(b)(2)(A)(ii) is the actual tax computed on the short period income. See the Example in the table below. Example: Assume the tax period is 201712; the taxable income for the five-month short period is $40,000; and the tax rates are as follows: 15% (percent) of income up to $50,000 25% of income from $50,000 to $75,000 34% of income more than $75,000 Note: Assume also that in doing the IRC 443(b)(2) alternate 12-month calculation, the income for the seven-month period following the five month short period is $50,000. For example, tax period 201712; the taxable income for the five-month short period is $40,000; the income for the seven-month period following the five-month short period is $50,000; taxable income for 12-month period is $90,000. See table below. Step Example Calculation Process Step 1 Regular annualization (IRC 443(b)(1)) $40,000 x 12 ÷ 5 = $96,000 (annualized income) $96,000 x tax rate (34% (percent) - $11,750) = $20,890 (annualized tax) $20,890 x 5 ÷ 12 = $8,704 (gross tax) Step 2 12-month period calculation (IRC 443(b)(2)(A)(i)) $90,000 x tax rate (34% - $11,750) = $18,850 (actual tax) $18,850 x 40,000 ÷ 90,000 = $8,378 Step 3 Short period calculation (IRC 443(b)(2)(A)(ii)) $40,000 x tax rate (15%) = $6,000 Step 4 Take the greater of Step 2 ($8,378) and Step 3 ($6,000), which in this example is $8,378. Step 5 The tax liability for the short period is the lesser of Step 1 ($8,704) and Step 4 ($8,378), which in this example is $8,378.

# Short Period Returns Due to Change of Accounting Period

3.12.16.20.2 (01-01-2021) Short Period Returns Due to Change of Accounting Period For tax periods beginning after December 31, 2017, the income tax rate for a corporation will be 21% (percent). Note: The Tax Cuts and Jobs Act of 2017 - Public Law (P.L.) No. 115-97 (H.R. 1), Section 13001 gives a 21% corporate rate effective for taxable years beginning after December 31, 2017. Annualized Tax with One Tax Rate - The formula for computing tax with one rate due to "Change of Accounting Period" is as follows: Step Item Applicable Period/Rate Equals Step 1 Taxable income × 12 / Number of months in tax period = Annualized Income Step 2 Annualized income × Applicable Tax Rate = Annualized Tax Step 3 Annualized tax × Number of months in tax period / 12 = Gross Tax Note: Compute using rounded figures. Example - The tax on a single corporation with the taxable income of $115,572.00 for the tax period beginning January 1, 2017, and ending September 30, 2017, is computed as follows: Step Example Calculation Process Step 1 $115,572.00 x 12 = $1,386,864.00 ÷ 9 = $154,096.00 Step 2 $154,096.00 x tax rate (39% (percent) - $16,750.00) = $43,347.44 Step 3 $43,347.44 x 9 ÷ 12 = $32,510.68 Days versus Months - If the taxpayer has used days to compute tax, verify the computation using days. This applies to the short period when a taxpayer is changing to/from a 52-53 week tax year, but not if such change results in a short period of more than 359 days, or less than seven days. The following is an example of a single corporation with a "change of accounting period" with 1 tax rate, taxable income of $10,501.00 and tax period from September 1, 2017, to December 31, 2017. Days versus Months $10,501.00 × 365 = $3,832,865.00 $3,832,865.00 ÷ 122 = $31,416.93 $31,416.93 × .15 = $4,712.54 $4,712.54 × 122 = $574,929.76 $574,929.76 ÷ 365 = $1,575.15 In the next example, the taxable income is $75,000 for 90 days of business in 2017. Days versus Months $75,000 × 365 = $27,375,000.00 $27,375,000.00 ÷ 90 = $304,166.67 $304,166.67 × .39 - $16,750 = $101,875.00 $101,875 × 90 = $9,168,750 $9,168,750 ÷ 365 = $25,119.86

# Manual Verifications

3.12.16.21 (01-01-2019) Manual Verifications The information within this section gives a breakdown of several types of manual verifications.

# "Y" Coded, Treasury Regulation Section 1.1502-76 Return

3.12.16.21.1 (01-01-2020) "Y" Coded, Treasury Regulation Section 1.1502-76 Return A "Y" coded, Treasury Regulation Section 1.1502-76, return is computed under normal corporate tax rates. The return is the last return of a subsidiary before its inclusion in a consolidated return. The Computer Condition Code "Y" must be entered to change the fiscal year ending.

# Personal Service Corporations

3.12.16.21.2 (01-01-2021) Personal Service Corporations For tax periods beginning before January 1, 2018, if the return is for a Personal Service Corporation, tax will be computed at a flat 35% (percent). For tax periods beginning January 1, 2018 (201801) and later, the income tax will be 21% (percent). Note: The Tax Cuts and Jobs Act of 2017 - Public Law (P.L.) No. 115-97 (H.R. 1), Section 13001 has a 21% corporate rate effective for taxable years beginning after December 31, 2017.

# Regulated Investment Companies

Form 1120-RIC is on the Error Resolution System (ERS). See IRM 3.12.251, Error Resolution - Corporation Income Tax Returns.

# Controlled Group Returns

3.12.16.21.4 (01-01-2020) Controlled Group Returns Controlled Groups are subject to a flat tax rate of 21% and can use only one $250,000 amount, for purposes of computing the accumulated earnings credit, per the Tax Cuts and Jobs Act (TCJA) of 2017, for taxable years beginning after December 31, 2017. A controlled group is a group of two or more corporations treated as one for determining the group's tax rates. For tax periods ending December 31, 1993 (199312), through November 30, 2018 (201811), a corporation with Taxable Income over $100,000: Besides paying its regular tax, they will pay an additional 5% tax on income that exceeds $100,000 up to $15,000,000, (not to exceed $11,750 in tax). Any corporation or members of a corporation of a controlled group that has Taxable Income that exceeds $15,000,000 will pay the above tax; plus an additional tax of 3% (not to exceed $100,000 in tax). Corporations who are members of a controlled group are also supposed to attach Schedule O (Form 1120), Consent Plan and Apportionment Schedule. Note: Refer to Schedule O (Form 1120), Consent Plan and Apportionment Schedule, for a Controlled Group for returns filed for tax periods beginning January 1, 2007, through November 30, 2018 (201811). Corporations that are members of a controlled group are instructed to check a particular box on their tax returns. On Form 1120-FSC, U.S. Income Tax Return of a Foreign Sales Corporation, the box is on Page 1 of the return ("Parent-subsidiary controlled group." ) and Page 5, Schedule J ("Check if the FSC is a member of a controlled group" ). See IRM 3.12.16.6.12, Field 03-M, Subsidiary Filer Code, for more information. Members of a controlled group will be treated as one corporation. If the Taxable Income exceeds $100,000, each member will pay the additional tax based on the part of the tax allocated above and agreed upon by each member. Each member should attach a schedule showing the computation of each member of the controlled group. When taxable income exceeds $100,000, and there is no additional tax present, send correspondence to the taxpayer requesting an apportionment plan or schedule for each member of the Controlled Group. When the taxpayer doesn't reply to our correspondence, see IRM 3.12.16.18, General "No Reply" Procedures, for more information. Note: Refer to Schedule O (Form 1120), Consent Plan and Apportionment Schedule, for a Controlled Group for returns filed for tax periods beginning January 1, 2007, through November 30, 2018 (201811).

# Legislative Changes Affecting Tax Computations

3.12.16.22 (01-01-2019) Legislative Changes Affecting Tax Computations The information within this section explains how tax computations are affected by legislative changes.

# Tax Cuts and Jobs Act (TCJA) of 2017

3.12.16.22.1 (01-01-2020) Tax Cuts and Jobs Act (TCJA) of 2017 Tax Cuts and Jobs Act of 2017, Public Law (P.L.) No. 115-97, Section 12001 - Repeal of tax for corporations. Act Section 12001 repeals the corporate alternative minimum tax, effective for taxable years beginning after December 31, 2017. Tax Cuts and Jobs Act of 2017, P.L. 115-97, Section 13001 - 21-percent corporate tax rate. Section 13001: Has a 21% corporate rate effective for taxable years beginning after December 31, 2017. For taxpayers subject to the normalization method of accounting (regulated public utilities), clarifies the normalization of excess tax reserves resulting from the reduction of corporate income tax rates (with respect to prior depreciation or recovery allowances taken on assets placed in service before the corporate reduction takes effect). Under the TCJA, a utility that reduces its excess tax reserve more rapidly or to a greater extent than under a specified accounting method is not treated as using the normalization method to reconcile the tax treatment of accelerated depreciation of its assets with its regulatory treatment (as in Section 168(i)(9)). TCJA further gives that a utility that does not use the normalization method must increase its income tax by the amount by which the excess tax reserve is reduced more rapidly or to a greater extent than permitted under the normalization method. Tax Cuts and Jobs Act of 2017, P.L. 115-97, Section 11001 - Modifications of Rates. Act Section 11001 replaces the existing individual income tax rate structure with a new rate structure: 10%, 12%, 22%, 24%, 32%, 35%, and 37%, effective for taxable years beginning after December 31, 2017, and before January 1, 2026. Form 1120-SF, U.S. Income Tax Return for Settlement Funds (Under Section 468B) tax rate changed to 37% (percent) for tax periods ending December 31, 2018, (201812) and later per Tax Cuts and Jobs Act of 2017, P.L. 115-97 (H.R. 1), Section 11001, (changed the Section 1 tax rates).

# Omnibus Budget Reconciliation Act of 1993 (OBRA)

3.12.16.22.2 (01-01-2019) Omnibus Budget Reconciliation Act of 1993 (OBRA) Omnibus Budget Reconciliation Act of 1993 (OBRA) made changes to the tax rates and the estimated tax rules that affected tax periods beginning after January 1, 1993. The Act also mandated a retroactive tax increase on corporate tax returns with tax periods of 199301-199311. This legislation established a new corporate tax rate structure - 15% marginal tax rate on taxable income up to $50,000; 25% on taxable income exceeding $50,000 up to $75,000; 34% on taxable income exceeding $75,000 up to $10,000,000; 35% on taxable income exceeding $10,000,000. Additionally, a 5% or 3% surtax may apply to certain levels of income as in the flush language of IRC 11(b). The flush language has: "In the case of a corporation which has taxable income more than $100,000 for any taxable year, the amount of tax determined under the preceding sentence for such taxable year must be increased by the lesser of (i) 5 percent of such excess, or (ii) $11,750. In the case of a corporation which has taxable income more than $15,000,000, the amount of the tax determined under the foregoing provisions of this paragraph shall be increased by an additional amount equal to the lesser of (i) 3 percent of such excess, or (ii) $100,000." The tax rate for Form 1120-ND, Return for Nuclear Decommissioning Funds and Certain Persons, decreased to 20% under OBRA for tax period 199601 and later. If the taxpayer's return straddles two tax periods with different rates, the return must be manually verified. The tax rate for Form 1120-ND, Return for Nuclear Decommissioning Funds and Certain Persons, changed to 22% under OBRA for tax period 199401 through 199512. If the taxpayer's return straddles two tax periods with different rates, the return must be manually verified. The tax rate for Form 1120-ND increased to 35% under OBRA for tax period 199301-199312. The tax rate for Form 1120-ND increased after the 1992 tax returns were filed, which made the tax for tax period ending in 199301-199311 retroactive. Form 1120-SF, U.S. Income Tax Return for Settlement Funds (Under Section 468B), which replaced Form 1120-DF, was included in OBRA. The Act increased the tax rate for Form 1120-SF to a maximum tax rate of 39.6%. It is also retroactive for tax periods 199301-199311. All the rules and regulations that applies to Form 1120-DF, apply to Form 1120-SF.

# Potential Frivolous Arguments for Examination Review

Exhibit 3.12.16-6 Potential Frivolous Arguments for Examination Review Potential Frivolous Argument Description Alleged Churches/First Amendment Income from non-religious sources and may claim a vow of poverty. Altered Form Altering any or all line items with the intent of facilitating non-compliance with the tax laws. Altered Jurat/Uniform Commercial Code (UCC) 1-207 or UCC 1-308 Return has income and deductions but the jurat was altered or stricken. May include reference to UCC 1-207/UCC 1-308 or a statement that the return was not signed under penalties of perjury. Amended Returns/Form 843 Claim Amended return or a Form 843, Claim for Refund and Request for Abatement, filed to obtain a total refund of all taxes paid in prior years, based on a tax avoidance argument. C-Filings This frivolous position includes the following four categories: Files a return claiming several types of deductions, credits, or overpayments/refunds that have no relation to reality and because of their outrageous character, qualify as frivolous returns. Files a return containing the filer's identifying information but does not request a refund, often lacking sufficient information to determine a tax liability. Files a return with several types of rambling dialogue or confusing arguments that no one could reasonably view as a good faith attempt to comply with the law. Files a return that attempts to send some type of message or protest to the IRS but doesn't include sufficient identifying information for the IRS to either determine the identity of the taxpayer or correspondent or return address. Challenges to Authority/Due Process Questions several administrative authorities such as delegation orders, summons authority, Privacy Act, etc. Argues that they must be afforded a hearing or a trial before taxes can be assessed or before property can be seized. Challenges to Authority/Title 26 or "law" in Other Documents Argues that Title 26 of the United States Code is not law because it was never enacted as named. Collections Issues Files frivolous documents contending that several collections issues are invalid (e.g., Offers in Compromise, Collection Due Process Requests, Installment Agreements, Appeals Requests, ) because they are not filed and signed by someone with delegated authority. They may have no certificate of assessment attached, do not comply in form or content with a state or local law, are not in a certain format or lack a valid Office of Management and Budget (OMB) number, or other frivolous positions. Disclaimer Submits a disclaimer stating, "disclaims the liability for the tax due," making the liability on the return zero. Fifth Amendment Assertion of the Fifth Amendment right against self-incrimination as a basis for not providing any financial information. Foreign Income Argues that United States citizens and residents are not subject to tax on their wages or other income derived from sources within the United States, as only foreign-based income or income received by nonresident aliens and foreign corporations from sources within the United States is taxable. Form 1099-OID (Original Issue Discount) An individual or business files a return reporting false amounts of income (generally "Other" or "Miscellaneous" income) and claims a false amount of income tax withholding approximately equal to the amount of falsely reported income. Although the returns report income, they do not calculate any tax due. Some of the returns have Form 1099-OID attached and some have Form 1096, Annual Summary and Transmittal of U.S. Information Returns. Other false financial instruments may be filed in the place of or in addition to the Form 1099-OID such as Form 2439, Notice to Shareholder of Undistributed Long-Term Capital Gains, promissory notes, bonds, sight drafts, etc. IRC 861 Business Employment Tax (BMF 861) Argument targets employers and advises them that wages are exempt from withholding. These taxpayers rely on Sections 861 through 865 of the Code and the regulations (in particular, Treasury Regulation §1.861-8), promoters of this scheme advise employers to stop withholding and paying payroll taxes on their employee's wages. In addition, some employers file amended payroll tax returns and request refunds of previously paid payroll taxes. IRS is a Private Organization/Collects Tribute, Not Taxes Argues that the IRS is an entity named the Internal Revenue and Tax Service, Inc., which was incorporated in Delaware in 1933, it is a collection agency for the Federal Reserve Bank or is part of the United Nations and is clandestinely leading the tax-paying public into a "new world order" . Not a Person Argues that a taxpayer is not a "person" within the meaning of Section 7701(a)(14). Obscene, Vulgar, Harassing Submits documents or other materials indicating that non-filing is due to dissatisfaction with tax policies or taxation in general. Often, this argument is expressed with obscene, vulgar, or crude language and characters in an extremely demeaning manner. Protest Against Government Action/Inaction Argues that refusal to file or pay is justified because they disagree with government policies or spending plans. Sixteenth Amendment Argues the Sixteenth Amendment was not properly ratified and therefore the federal government does not have the legal authority to collect an income tax without apportionment. Straw Men Argues the government has created an entity separate and distinct from the taxpayer - a "straw man" and any tax obligations are exclusively those of the "straw man" . Taxes are Voluntary/Law Does Not Require Submits a return, amended return or correspondence that argues income taxes are voluntary. U.S. vs. Long Submits a return with zero money amounts. To explain the zeroes inserted on the form the individual references "U.S. vs. Long" . Unsigned Returns The individual completes a return but doesn't sign. A statement indicating disagreement with the tax system is attached or added to the return. Valuation Income is not taxable because of the declining fair market value of the dollar, because the dollar is not backed by gold/silver, because the value of services is offset by the value of the labor (barter income), etc. Zero Returns Submits a return with zero money amounts on all or most line items on the form (e.g., IRC 861, Form 2439, OID, and other BMF filings that claim no income and request refunds). See Rev. Rul. 2004-34. A statement is attached claiming there is no section of the Internal Revenue Code that established an income tax liability. The statement may also have arguments regarding the definition of income. There are several variations on this type of filing such as those bearing the words "nunc pro tunc" and "not liable" . Note: Returns having only zeros, no entries, are blank, or show "None" , "Not Liable" , etc., with no evidence of frivolous arguments are not to be considered as frivolous returns Other All others including those in Notice 2010-33 or any subsequent superseding notice. See also The Truth About Frivolous Tax Arguments on IRS.gov. This category includes non-filer accounts resulting from initial compliance check such as cross-reference Taxpayer Identification Numbers (TINs). Note: Frivolous arguments citing "Collection Due Process (CDP)" should be reviewed by Collections for possible referral to Appeals. Refer to IRM 5.19.8, Collection Appeal Rights, for more information.
