# Background

4.119.1.1.1 (10-18-2024) Background This IRM 4.119.1 contains information for clerks on their responsibilities relating to the BUR manual clerical process for Form 1120 and Form 1041. The content in this IRM has been updated to reflect manual case processing. The Business Master File BMF Underreporter(BUR) program is separated into four phases for Form 1120 and Form 1041: Note: See Exhibit 4.119.1-1,Glossary, for terms, acronyms and abbreviations used in BUR program. Case Analysis (may also be referred to as Screening) Response, includes both Letter 2531 and Letter 2030 Tax examiners use Correspondex(CRX) Letters (e.g.: Letter 4550-C, or Letter 4551-C ) to obtain or provide additional information Statutory Notice, legally required final notice (abbreviated as STAT) Reconsiderations (closed case correspondence, may also be referred to as Recon) In order to distinguish guidelines relative to Letter 2531, Letter 2030 and/or Letter 3219-B from guidelines relative to Correspondex Letters, the following statements in this IRM are true: Any references to "notice" or "notices" refer to Letter 2531, Letter 2030 and/or Letter 3219-B (unless otherwise specified). Any references to "letter" or "letters" refer to Correspondex (CRX) Letters (unless otherwise specified). The Case Analysis phase is the initial screening of a case. A technical determination is made whether: A notice needs to be generated A case needs to be referred and/or researched A case can be closed without further action A case should be transferred to another function The clerical functions to support these processes are: Ordering returns and opening case controls Establish/update Transaction Code (TC) 925 with Process Codes Building batches Associating Folders, returns, and/or transcripts (DCI) to case files Refiling closed cases Disassembling Batch Trucks Pulling notices identified as erroneous from the notice mailout Preparing and Reconciling notices for mailout Preparing cases for transfer or referral to other areas Setting up suspense files in Case Sequence Number (CSN) order The Response Phase of the BUR Program is the resolution of the BUR issue addressed in the: Letter 2531, Initial Contact Letter Letter 2030, Notice Proposing Adjustment to Income, Payments, or Credits Subsequent Correspondex(e.g., Letter 4552-C,Letter 4550-C, Letter 4551-C, etc.) Note: Tax examiners use Correspondex (CRX) letters to obtain or provide additional information. Recomputed Letter 2030 The Letter 2531 or the Letter 2030 issues can be resolved by a response from the taxpayer. If the response does not resolve the issue, there is no response, or if the notice is undeliverable, a Letter 2030 or a Statutory Notice is issued. The response may result in: Closure and refile Assessment Miscellaneous Referral Research (Unit Suspense) Transfer to another area (e.g., Examination or Criminal Investigation) Additional correspondence to resolve the issue The clerical functions to support these processes are: Building batches Associating responses to the Letter 2531, Letter 2030, recomputed notices, and Correspondex letters with the case files Verifying Process Codes Disassembling Batch Trucks Preparing cases for transfer or referral to other areas Mailing additional correspondence Sending closed cases to the campus files to be sent to the Federal Records Centers (FRC) to be refiled Preparing no response cases for continued processing; Letter 2531 to Letter 2030 and Letter 2030 to Statutory Notice, including all exception handling The Statutory Notice phase of the BUR Program is the resolution of the BUR issue addressed in the Statutory Notice of Deficiency (Letter 3219-B) and Waiver (Form 4089, Notice of Deficiency - Waiver). If the response does not resolve the issue, there is no response, or if the notice is undeliverable, the Statutory Notice is defaulted. Note: The default process is the preparation of Statutory Notice cases for assessment and closure, including all exception handling. The Statutory Notice issues can be resolved by a response from the taxpayer. The case is defaulted when: Responses from the taxpayer do not resolve the issue(s), and the Statutory suspense period has expired No response is received The Post Office has returned the notice as undeliverable and IRS has no record of a better address. See IRM 4.119.1.5.29.3, Undeliverable Statutory Notices, for additional information The clerical functions to support these processes are: Building batches Associating responses to the STAT, recomputed notices, and Correspondex letters with the case files Verifying Process Codes Disassembling Batch Trucks Preparing cases for transfer or referral to other areas Mailing additional correspondence Sending closed cases to the campus files to be sent to the Federal Records Centers (FRC) to be refiled Preparing no response cases for continued processing to default the Statutory Notice, including all exception handling The Reconsideration phase of the BUR program is the handling/resolution of correspondence received from a case that is closed. Correspondence from closed cases is primarily on the following three types: A taxpayer request for a change in the BUR assessment made on the case. Correspondence that does not require a tax examiner to resolve. These are not requests for a change to the BUR assessment. Misrouted correspondence that has no impact on the previous BUR case. The clerical functions to support these processes are: Building batches Research response for closed status Pull requested cases when needed Sending closed cases to the campus files to be sent to the Federal Records Centers (FRC) to be refiled Disassembling Batch Trucks Verifying Process Codes

# Authority

4.119.1.1.2 (08-15-2017) Authority Chapter 61 of the Internal Revenue Code (Information and Returns), Sub chapter A (Records and Returns), Part III (Information Returns), sections 6031 – 6059, contain the requirements for the filing of information returns for income reporting purposes. Rev Proc 2005-32 identifies taxpayer contacts to verify a discrepancy between the taxpayer's tax return and an information return, or between a tax return and information otherwise in the IRS's possession as taxpayer contacts and other actions not considered an examination, inspection or reopening.

# Roles and Responsibilities

4.119.1.1.3 (07-29-2020) Roles and Responsibilities The Director of Examination Field & Campus Policy is the executive responsible for the BMF Underreporter program. The Team Manager is responsible to oversee the clerical function in BMF BUR. The BUR clerks are responsible to order, batch, mail notices and release all cases worked by the tax examiners in a timely manner.

# Program Management and Review

4.119.1.1.4 (10-01-2018) Program Management and Review Program Reports listed below are used to monitor the BUR inventory and identify multiple IDRS controls: IDRS CCA 4243 (generated weekly and contains all cases controlled to BUR employees) IDRS CCA 4244 (identifies cases when two or more employees have an open control base on the same TIN) Program Effectiveness. The program goals are measured by the Inventory Status Report prepared by the Workload Planning and Analysis staff.

# Program Controls

4.119.1.1.5 (07-14-2022) Program Controls A guiding principle of security within IRS is "limiting access to assets based on need" . This principle is the basic premise for most of the IRS security programs. When applied to BUR, this translates to limiting access to documents on a need-to-know basis. The repository is used to limit access to BUR content. The administrator grants or denies access to the repository.

# Terms and Acronyms

4.119.1.1.6 (10-18-2024) Terms and Acronyms See Exhibit 4.119.1-1 Glossary for a list used in this IRM and BUR processing.

# Related Resources

4.119.1.1.7 (10-18-2024) Related Resources In conjunction with this IRM, clerks can reference the TAS IRM 13.1.7, and use the Integrated Automation Technologies (IAT) tools to perform their duties.

# Maintaining Documents In BMF BUR

4.119.1.2 (10-18-2024) Maintaining Documents In BMF BUR Form 3210, Transmittal, Receipt and Control Records - Correspondence, transmittal letters, reports, and transmittal receipt and control documents, etc., pertaining to receiving, controlling and transmitting tax returns, taxpayer account registers, and related documents should be maintained within the Operation for one year from the date the transmittal was prepared. After the one year period the document can be destroyed in accordance with local waste procedure Certified and Registered Mail Records - Stat Notice Certified listings should be maintained within the Operation for three years after the closeout of the tax year. At the end of the three year period, ship the listings to the appropriate FRC. The form and instructions can be found at Records Transmittal and Receipt and Preparing the standard Form 135(SF 135) Records Transmittal and Receipt

# Taxpayer Advocate Service

4.119.1.3 (10-18-2024) Taxpayer Advocate Service Even though the IRS strives to improve its systems and provide better service, some taxpayers still have difficulty in getting solutions to their problems or appropriate, timely responses to their inquiries. The purpose of the Taxpayer Advocate Service (TAS) is to give taxpayers someone to speak for them within the IRS. TAS is an independent organization within the IRS. The Taxpayer Bill of Rights (TBOR) lists rights that already existed in the tax code, putting them in simple language and grouping them into 10 fundamental rights. Employees are responsible for being familiar with and acting in accord with taxpayer rights. See IRC 7803(a)(3), Execution of Duties in Accord with Taxpayer Rights. For additional information about the Taxpayer Bill of Rights, see Taxpayer Bill of Rights.

# Integrated Automation Technologies (IAT)

4.119.1.4 (10-18-2024) Integrated Automation Technologies (IAT) BUR employees are mandated to use the Integrated Automation Technologies (IAT) tools. When an action must be taken on IDRS and an IAT tool is available, BUR employees will use the IAT tools to complete the action using the IAT tool. The IAT tools assist the user with IDRS research and input. If an IAT tool is not functioning properly, contact the lead. Continue working the case using IDRS.

# General Case Processing

4.119.1.5 (10-18-2024) General Case Processing This section deals with general information about the BMF Underreporter program and BUR clerical case processing. The topics in this section of the IRM are listed in alphabetical order for ease of research and use.

# Action 61/Policy Statement P-21-3 Guidelines

4.119.1.5.1 (12-03-2025) Action 61/Policy Statement P-21-3 Guidelines Policy Statement P-21-3 (formerly known as Action 61) Guidelines are the result of a task force initiated to provide timely and quality responses to taxpayer correspondence. The general guidelines are: A quality response is an accurate and professional communication which, based on information provided, resolves the taxpayer issues, requests additional information from the taxpayer, or notifies the taxpayer we have requested information from outside the IRS. A quality response is timely when initiated within 30 calendar days of the IRS received date. When a quality response cannot be issued timely, an interim response must be initiated by the 30th calendar day from the IRS received date. Use IDRS and the IAT tool to initiate Letter 5825-C. Note: Use the CCA report 4243 to determine cases that require an interim letter. All interim letters should inform the taxpayer when a final response can be expected and provide a contact name and number for additional inquiries. Responses received with an IRS received date of 30 days old or older, must have an interim letter sent before being batched. BUR Coordinator will generate a list of cases requiring an interim letter, (Letter 5825-C ) when the IRS received date exceeds 23 days. A Letter 5825-C is sent on cases in Batch Types (BT): 430, 431 440, 441 510, 511 530, 531 540, 541 710, 711 730, 731 740, 741 940, 941 Note: The Batch must be assigned to the clerical generic Integrated Data Retrieval System (IDRS) number 0481100000 for the clerical function to initiate the interim letter.

# Address Changes

4.119.1.5.2 (09-09-2014) Address Changes A response may require a new address change to be entered on IDRS using CC ENREQ. Use normal batch building procedures when processing responses requiring an address change. Note: Tax Examiners will update the address.

# Assessments

4.119.1.5.3 (10-18-2024) Assessments An assessment record will be generated on all closed cases with the exception of screening closures and PC 4890. It is optional to have an assessment record created on referral and other closure process codes. ALL assessments must be input via IDRS. All cases with an assessment other than zero will include an IDRS CC:ADJ54 adjustment print-out. Note: If the DCI shows an assessment and/or penalty amount other than zero and the IDRS CC:ADJ54 print-out is not present, give the case to the Lead Clerk. Compare the following transaction codes on the IDRS CC:ADJ54 print-out assessment information to the DCI assessment information to ensure they match: ADJ 54 Transaction Code DCI TC 290 Assessed Tax TC 291 Assessed Tax Note: TE will show the amount in parenthesis. For example (500). TC 680/787 or TC 240 Assessed Penalty TC 766/767 or TC 806/807 Withholding Caution: If the tax, withholding, and/or penalty amounts on the IDRS CC:ADJ54 adjustment print-out do not match the DCI, give the case to the Lead Clerk. The TE verifies and/or inputs the necessary assessment information for all PCs. Assessment volumes are limited for each blocking series. The BUR Coordinator and the Computer Service scheduler ensure that daily limits per blocking series are set correctly, and that the IDRS assessments do not exceed the daily input limitations. 2,000 for Blocking Series 55 (550–569) 1120 BMF URP Refile DLN for paper returns Letter 2531 or Letter 2030 1,000 for Blocking Series 57 (570–579) 1120 BMF URP Non- Refile DLN for electronically filed returns Letter 2531 or Letter 2030 1,000 for Blocking Series 58 (580–589) 1120 BMF URP Adj Stat Notice Refile DLN for paper returns Stat 1,000 for Blocking Series 59 (590–599) 1120 BMF URP Adj Stat Notice Non-Refile DLN for electronically filed returns 1,000 for Blocking Series 64 (640-649) 1040 series, 1041, BMF URP Refile DLN for paper filed returns 1,000 for Blocking Series 89 (890-899) 1040 series, 1041, and 1065 BMF URP Refile DLN for electronically filed returns To accommodate increased volumes of inventory, the File Location Codes (FLC) (first two digits of the Document Locator Number) (DLN) for BUR assessments have been expanded. If daily volumes for a blocking series are exceeded, the additional assessments roll to the next FLC per the Table below: BUR Site File Location Codes (in the order used) Ogden 29, 60, 78, 81, 82, 83, 84, 85, 86, 87, 88, 91, 92, 93, 99 All assessments received from the tax examiners will be in adjustment sequence series order. Cases Must be maintained in this order during the shipping to Files. Ship assessments to the Files Operation for Computer association using Form 12547. Files uses the employee IDRS number to assist with the association of the assessment to the case contents received from BMF BUR. The employee number is composed of ten digits as follows: The first two digits represent the Campus The next three digits represent the BUR Employee Group (EGC) Code (811) The last five digits represent the BUR Employee IDRS Number Note: The Campus should work with the Files Operation to determine how to prepare and ship the assessments.

# Case Sequence Number (CSN)

4.119.1.5.4 (10-18-2024) Case Sequence Number (CSN) A CSN is the tracking number of a case. Each case is assigned a CSN which is used to locate the case throughout the BUR process. All cases are filed in CSN order in BUR designated areas or suspense files.

# Charge-outs (Form 4251)

4.119.1.5.5 (08-31-2016) Charge-outs (Form 4251) Charge-outs (Form 4251) are generated from the Federal Records Center (FRC) when ordering the original return via IDRS using CC ESTABD definer O. Files will take the following actions to fulfill the return request: If the return has not been retired to the Federal Records Center (FRC) then the Campus Document Retention Files Operation pulls the return and routes it to the BUR Operation. If the return has been retired to the FRC then the Campus Document Retention Files Operation routes the charge-out to the appropriate FRC. The FRC pulls the return and routes it to the BUR Operation. If the return is not available then the FRC notes the available charge-out information on the Requestor Copy, which is forwarded to the appropriate campus with the charge-out information. Reorder the return and suspend for 60 additional days. Note: If the second attempt to secure the return is not successful, give the Form 4251 to the Lead Clerk. Reminder: Do not batch a Form 4251 without a return attached. There are certain File Location Codes that indicate the tax return was filed electronically. See IRM 4.119.1.5.11,Modernized e File System, for a complete list of these Codes.

# Case Contents

4.119.1.5.6 (10-18-2024) Case Contents Clerical is responsible for the following: A tax return if paper filed Data Collection Instrument sheet Folder Paper tax returns and charge-outs are forwarded to the BUR clerical area for sorting and batching based on workload demands.

# Correspondex Letters

4.119.1.5.7 (12-12-2014) Correspondex Letters A Correspondex letter is issued to taxpayers when the case requires additional information (e.g.,Letter 4552-C,Letter 4550-C ). Cases that have had a letter issued will have an Internal Process Code (IPC) 43LT, 45LT, 47LT and 49LT on the folder. Note: These letters can be used as a response to our notice. If a letter is received as a fax/response, research IDRS CC TXMODA to locate case. Pull folder and associate with the case and batch into the appropriate batch type. If no response is received during Letter 2030 phase and the correspondex letter time has expired, the tax examiner will issue a STAT notice. Cases with letters issued during the STAT phase are monitored by the clerical function after the batch truck has been disassembled. Place cases in the appropriate suspense batch after the batch truck is disassembled. Letter 2531 Letter Suspense held in technical unit suspense Letter 2030 Letter Suspense held in technical unit suspense Statutory Notice Suspense held in clerical suspense Reconsideration Suspense held in the technical unit suspense Statutory Notice Letter (IPC 47PH and 47LT) cases are filed under the original Statutory Notice case sequence number. Reconsideration Letter internal process code 49LT, 49PH cases will be held and monitored in the teams unit suspense. Cases with IPCs 43PH or 45PH have taxpayer correspondence in the folder.

# Letter Attachments

4.119.1.5.8 (09-30-2015) Letter Attachments Collect Correspondex letter attachments from designated clerical area. Create a Form 12547, Document Transmittal, and complete sections 1 and 3. Associate all Correspondex letters with Form 12547 and route to the CRX Function.

# Disaster Area Cases

4.119.1.5.9 (12-03-2025) Disaster Area Cases The BUR Coordinator alerts the clerical function of zip codes for specific declared disaster based on IRS Disaster Relief Memorandum. Follow coordinators instructions on proper handling of declared disaster area cases. Freeze Code -S prevents the case from being defaulted. Freeze Code -O prevents any notices from being issued or defaulted. Always be aware of the Statute Expiration Date. You must ensure that the Statute of Limitations is protected for all assessments. Do not hold these cases beyond January 15th before the statute year. After this date, all cases must be given to the Statute Coordinator for default assessments. Cases identified as meeting disaster criteria are placed in a designated area in the BUR clerical files according to the disaster expiration date and phase. Note: Cases identified as being in a Disaster ZIP will not age until after the Disaster ZIP end date has expired. Reminder: If a response is received before the disaster expiration date has expired, continue normal batching procedures. Cases meeting the disaster criteria are updated using IDRS CC: TXMODA and ACTON to 4XMRDSMMDD. Note: MMDD is the disaster expiration date for the freeze codes above.

# Docketed Appeals Cases

4.119.1.5.10 (12-03-2025) Docketed Appeals Cases Taxpayers generally have 90 days to petition the Tax Court to dispute a Statutory Notice of Deficiency. If the Statutory Notice of Deficiency is addressed to a person outside of the United States, the time is extended to 150 days. Note: Disaster relief may also extend the period a taxpayer has to petition Tax Court. These cases remain in Statutory suspense until the disaster end date expires. Docketed cases are high priority. Work these as soon as they are received. Docket procedures should be completed within 7 calendar days of BUR receiving the request. Note: If a response is received on a case that has been closed PC 4800, it should be treated as a Recon. Newly docketed Tax Court cases are available on the eCITE daily New Docketed Case List By Source, which contains the following information: Docket number Date of the Statutory Notice Business name, address and TIN (taxpayer identification number) Tax Years in Statutory Notice, Tax Years Petitioned to U. S. Tax Court (Tax Year) Source of Statutory Notice, Appeals Office and Counsel Office information Campus function and location number in a high-lighted box to the right of the entry Research IDRS if the case has been closed with process codes 4340, 4400, 4420, 4440, 4460, 4550, 4600, 4610, 4630, 4660, 4810, 4820, 4830, complete Form 14121 No Change Certification. Sign and fax the form to the Fresno Appeals APS DIMS Team and the assigned Counsel location on the docket list. If research indicates the BUR case is closed with process codes other than listed above: Exception: Give the case to the Lead Clerk when the case is closed PC 4940. Caution: If the docket listing shows CDP or DUE PROCESS COLLECTION CASE on a BUR case, do not open an AIMS control or send any case information listed above to Appeals. Notate on the Form 3210"Closed BUR Case" and "Request return if needed" . Print all notices, and the Case Contents, Tax Account (TXMODA), IRPTR Information Returns, DCI, and case notes if present. Print the Statutory Notice of Deficiency for all Stat notices. Establish the case on Audit Information Management System (AIMS) for Appeals using IDRS Command Code (CC): AM424A and the Appeals Office Code. Research SERP, under the Who/Where tab, to link to the Appeals Case Routing for current Appeals Office addresses and routing instructions. Note: See Document 6209 for information on reversing transaction codes, AIMS actions and closing an IDRS control base. Attach a print of the AIMS opening action showing request completed. Route the case to the address shown in the "Exam & all other Non- Collection Cases" section of the following web page.: Case Routing Into The Independent Office Of Appeals If research indicates the BUR case is open: Step BUR case is open 1. Research for the CSN. 2. Locate and pull each open case. If the case is assigned to a unit or tax examiner, contact the unit or tax examiner to obtain the case. If not assigned give case to the Appeals subject matter expert. Note: All open cases must be seen by a TE to determine if a non statutory issue exists. 3. If non statutory conditions exist, the TE will print all notices, Case Contents, Tax Account (TXMODA), IRPTR Information Returns, DCI, case history sheet if present, and return case to clerical. Follow all steps below except 6&7. 4. If non statutory condition does not exist, the TE will return the case to clerical. When case is returned, follow all steps below. 5. Prepare Form 3210 and record the name, TIN and tax year for each case. Note: If the case is MeF notate, "MeF return" on Form 3210 transmittal. 6. Print all notices, Case Contents, Tax Account (TXMODA), IRPTR Information Returns, DCI, case notes, and associate these items with the case file. 7. Print the Statutory Notice of Deficiency for all Stat notices issued. Note: If unable to locate the Statutory Notice of Deficiency see (7) below. 8. Establish the case on Audit Information Management System (AIMS) for Appeals using IDRS Command Code (CC): AM424A and the Appeals Office Code. Research SERP, under the Who/Where tab, to link to the Appeals Case Routing for current Appeals Office addresses and routing instructions. Note: See Document 6209 for information on reversing transaction codes, AIMS actions and closing an IDRS control base. 9. Attach a print of the AIMS opening action showing request completed. 10. Input TC 925 with Process Code 4800 on IDRS using CC: REQ77/FRM77 11. Write PC 4800 and SEID on the case folder and DCI, update the activity and close the control base using IDRS CC: TXMODA and ACTON. 12. Using IDRS CC ESTABD definer T, recharge the documents (paper returns) and route the case to the Ogden Campus Appeals Office. Note: Appeals may also request a copy of the Certified Mail Listing in order to verify the date and address used to mail the Statutory Notice. Locate, copy and sanitize the appropriate page of the Certified Mail Listing and include it with the Appeals package. This listing is maintained in the clerical function if needed. If unable to locate the Statutory Notice of Deficiency take the following actions: Search the case file for the Statutory Notice of Deficiency for the notice date of the missing copy. If found, photocopy and send. If not able to locate write "SNOD not available" on the Form 3210 transmittal.

# Modernized e File System

4.119.1.5.11 (07-28-2023) Modernized e File System Modernized e-File (MeF) is a web based system that allows electronic filing of Tax Returns through the Internet. All electronically transmitted returns are identified by a unique Document Locator Number (DLN). The following File Location Codes (FLC) have been designated for the electronic filing of income tax returns. The second number listed is the roll over FLC used when a site exhausts the regular FLC for a given processing date. File Location Code Processing Campus 60, 78, 88, 92, 93 Ogden Campus (OSC) Employees needing a MeF return can obtain it through the Employee User Portal (EUP). Note: You must be a registered user. A request using the Business Entitlement Access Request System (BEARS) is needed to gain access to this application. Electronically filed (MeF) returns do not have paper copies stored in Campus Document Retention, Files Operation, for associating taxpayer correspondence. Therefore, it is not possible to send copies of attachments/responses to Document Retention, Files Operation, for association with an MeF DLN.

# Examination Closures

4.119.1.5.12 (09-09-2014) Examination Closures If a case has been requested for transfer to Campus Examination, or by an Area Office, refer to BUR Coordinator (PC 4110, 4130, 4350, 4380, 4560, 4570, 4590, 4780, 4790).

# Folders (Case Information)

4.119.1.5.13 (08-15-2017) Folders (Case Information) The case information is printed on the top of the folders. The following is included as part of the printed case: Taxpayer Identification Number (TIN) Case Sequence Number (CSN) Tax Year Tax Form The case information is stored in a database generated by headquarters and given to the clerical function. Folders are initially produced for all cases prior to batching. Follow campus directions for printing folders. When folders are printed: Ensure all folders are printed. Associate transcripts and returns if applicable by verifying the information on the folder matches the case. Note: Case contents should be face up. If the folder for a case cannot be located or is not legible, manually create a case folder with the necessary information above and write possible duplicate on the folder. Place the completed case folder - keeping in strict CSN order - in the designated area or suspense file. Compare extra returns to the empty folders, if a match is found inter-file the foldered cases.

If a mutilated notice is returned to the site more than 5 days after the notice date: Pull the case and indicate "Mutilated" on the folder. Transfer the case to the TE who input the notice process code, or to a designated SEID for generation of another notice. Give the case to the technical unit to create a new notice. When a disaster area is declared and the IRS grants tax relief, the BUR Coordinator issues a designated disaster ZIP Codes list. Based on the disaster type and the dates, the BUR clerical function will compare all notices to the designated disaster ZIP Codes list to determine if it is necessary to suppress the notices. If the notice ZIP code is on the disaster ZIP Codes list to suppress the notices, follow the instructions for BT 83X at IRM 4.119.1.8.32, Batch Type (BT) 83X (Declared Disasters). Note: There may be occasions when the BUR Coordinator issues special handling instructions for disaster cases.

The original Certified Mail Listing and Registered Mail Listing is maintained in clerical as follows: Clerical associates the Certified Mail Manifest and the RML listings with the certified notices for mailing. The U.S. Post Office stamps the date the listing was received and returns it to BMF BUR. Clerical stores the listings in the designated log book.

# General Batch Information

4.119.1.7 (10-01-2018) General Batch Information BUR uses a series of batches to control and monitor inventory. Cases from Form 1120 and Form 1041 move from batch to batch as significant actions take place. Manually built batches for Form 1120 and Form 1041 use the same process procedures but must remain separated by form type and tax year. When building batches for: Form type 1120, the third digit will be zero Form type 1041, the third digit will be one Batches are built in the order the TINs are entered. Note: Returns (cases) must be kept in the order in which they are built.

# Description of Batch Numbers

4.119.1.7.1 (09-30-2015) Description of Batch Numbers A batch number is a six-digit number that is used to describe the physical location or the stage of processing for a case file. The first three numbers of every batch number are used to describe/define the batch and Form type. The next three numbers are used to describe/define the sequential number of a batch (e.g., 001, 002, 003, etc, through 999).

# Batch Building - General

4.119.1.7.2 (09-09-2014) Batch Building - General When cases are being assigned to a batch, there are specific stated requirements that must be met. The BUR Coordinator sets the maximum volume for each work unit and batch. When the batch has been assembled, print the appropriate Work Unit listings by batch number. The listing is used as a transmittal document and can also be used to verify batch contents. The verification of batch contents is a local management decision. For additional information, see IRM 4.119.1.12.2, Work Unit Listings.

# Screening Batch Building (Batch Type (BT) 310, 311, 340, 341)

4.119.1.7.2.1 (09-04-2019) Screening Batch Building (Batch Type (BT) 310, 311, 340, 341) The BUR inventory is ordered in groups referred to as correlations and each case is assigned a CSN. Initial batch building is also referred to as Case Analysis and Screening. An IDRS control base is opened on each case using the following: Access IDRS CC: TXMODA. Open the control using IDRS CC: ACTON accordingly C#,31XSCREEN,B,MISC 0481100000,*. Cases are manually built by Form and Year (BT 310 for Form 1120 and BT 311 for Form 1041). Returns (paper filed) are received from Campus Files and Federal Records Centers, stapled behind Form 4251, Return Charge-Out. Note: Do not build Form 4251, without a return. Treat as Classified Waste. Electronically filed returns (MeF) Form 1120 and Form 1041 cases do not receive a Form 4251, Return Charge-Out. For specifics on identifying these cases, see IRM 4.119.1.5.11, Modernized e File. To build a screening batch: Identify next batch number to be built. Update batch inventory. Access IDRS CC: TXMODA. Update the control using IDRS CC: ACTON accordingly CXX,31XXXXWUXX,B,MISC. When the maximum volume for the batch has been reached or there are no more cases to be built to the batch, complete the transmittal sheet with batch number, Tax Year, and volumes (batch and work units). Complete a work unit (WU) listing with Batch and WU number, Tax Year, Volume and TIN's for each work unit. Place copy of the transmittal and listing with the batch. Deliver the batch to the designated area. If cases cannot be built into the batch take to Lead Clerk. If loose documents (1099's, K-1 schedules, etc.) are found in screening, take the following actions: Research BUR and take appropriate steps to associate with the case. If not in BMF BUR, research IDRS to determine handling.

# Response Batch Building (Batch Types (BT) 430, 431, 440, 441, 510, 511, 530, 531, 540, 541, 710, 711, 730, 731, 740 and 741)

4.119.1.7.2.2 (09-04-2019) Response Batch Building (Batch Types (BT) 430, 431, 440, 441, 510, 511, 530, 531, 540, 541, 710, 711, 730, 731, 740 and 741) Responses should have undergone several sorts for tax year, type of response, and received date before response batch building begins. Prior to entering the TIN into a response batch, verify the IRS received date. The IRS received date is determined by following the priority criteria listed below: Oldest IRS received date stamped on correspondence. Envelope postmark date. Signature date. Current date. When a faxed response is received, the IRS received date is determined by the following priority criteria listed below: Fax date (printed on fax). Caution: The fax date is sometimes incorrect, use caution when determining whether to use this date. BUR received date stamped on correspondence. Signature date. Current date. Received dates must be built by week ending age dates for all non priority batch types: BT 430, 431, 510, 511, 530, 531 710, 711, 730, and 731. To build a response batch: Get the assigned work. Pull the cases and associate the appropriate response with the case file. Identify next batch number to be built. Update batch inventory. Access IDRS CC: TXMODA. Update the control using IDRS CC: ACTON accordingly CXX,XXXXXXWUXX,A,BURX→0481100000,MMDDYYYY. Note: "MMDDYYYY" represents the IRS Received Date of the correspondence. Caution: Ensure all responses are built into the appropriate batch type based on the most current action taken on the case. Be sure two responses are not stuck together. When the maximum volume for the batch has been reached or there are no more cases to be built to the batch, complete the transmittal sheet with batch number, Tax Year, batch date, and volumes (batch and work units). Complete a work unit (WU) listing with Batch and WU number, Tax Year, Volume and TIN's for each work unit. Place copy of the transmittal and listing with the batch. Deliver the batch to the designated area. If cases cannot be built into the batch take to Lead Clerk. For additional information, see IRM 4.119.1.7.3, Pull Cases. If IDRS displays the case has been closed with a BUR Process Code, place the response in the designated area for closed cases. See IRM 4.119.1.8.33, Closure Suspense for more information.
