Program Scope and Objectives

2.3.73.1 (12-31-2025) Program Scope and Objectives The mission of the Tax Data On-Line Branch is to provide customers top quality access to Corporate Data by planning, updating, scheduling, programming, implementing, and maintaining applications and building systems. Tax Data On Line consists of TRDB, RTFOL, RPVOL, DDB, NAP, and SCAP/SCOP systems. Purpose: TRDB is a relational data base that stores tax return information from sources such as Generalized Mainline Framework (GMF), Modernized eFile (MeF), Error Resolution System (ERS) and others. This includes data as outlined in IRM 2.3.73.2(1). Audience: Tax Analysts, Research Analysts, Auditors, and Fraud Detection Analysts in LMSB, SBSE, TEGE, Appeals, TAS, CI, MITS, and TS. Policy Owner:Kaschit Pandya, Chief Information Officer. Program Owner: TS is responsible for the administration, procedures, and updates related to the program. Primary Stakeholders: Taxpayer Services (TS), Large Business and International (LB&I), Small Business Self-Employed (SB/SE), Tax Exempt and Government Entities (TE/GE), and Enterprise Operations (EOPS) Program Goals: TRDB is responsible for loading and updating data onto the TRDB databases (a separate database has been created for every processing year since 1998) and ensuring that the data can be retrieved to provide the necessary information so that users may process tax accounts accordingly. TRDB also provides data extracts when a large number of records are needed via tickler file.

Background

2.3.73.1.1 (01-01-2025) Background The Tax Return Database (TRDB) is the system of record for storing electronic filed (ELF) tax returns beginning with tax year 1998 through 2012 for IMF, and 2015 for BMF. Although ELF has been retired, all tax returns processed by TRDB will remain on the TRDB database until they no longer meet retention criteria. TRDB will continue storing the following data: 1) Corrections made to the tax return data in the Error Resolution System (ERS), Generalized Mainline Framework (GMF), and Generalized Unpostable Framework (GUF) as it is processed through the submission pipeline; 2) Status (e.g., suspended, corrected, posted), Processing Codes (e.g., code and edit condition, notice, audit, re sequence, unpostable) and history information as it is processed through the submission pipeline. A final status of 'Additional Tax Assessment' is recorded if an adjustment is made to a return after it has posted to the Master File. The adjustment is not stored on TRDB; 3) All MeF and paper filed returns that are also found on the IMF and BMF Return Transaction Files (RTF) beginning with processing year 2003. These returns are input to TRDB after GMF perfection rather than from original taxpayer submitted data also known as t-lines. Only the portion of the return that is part of the GMF transaction will be present (RTF data); 4) RAL (Refund Anticipation Loan Code); 5) Reject codes for tax returns that have rejected from MeF. TRDB data is accessed through IDRS via SACS using command codes TRDBV and TRERS. TRDGRA Transcribed Form 8453 (Paper Signature) data is likewise stored on TRDB and is available through command code R8453. In January 2006, TRDB began aging expired (inactive CSED) returns from the data base.

Program Management and Review

2.3.73.1.4 (12-23-2024) Program Management and Review Program ReportsBMF is the primary source of data for BRTFOL data repository stored at ECC mainframe. The command code TRDBV is used to retrieve the individual tax return information stored for the current processing year and three prior processing years. Program Effectiveness: TRDB stores the following data: 1) Corrections made to the tax return data in the Error Resolution System (ERS), Generalized Mainline Framework (GMF), and Generalized Unpostable Framework (GUF) as it is processed through the submission pipeline; 2) Status (e.g., suspended, corrected, posted), Processing Codes (e.g., code and edit condition, notice, audit, resequence, unpostable) and history information as it is processed through the submission pipeline. A final status of 'Additional Tax Assessment' is recorded if an adjustment is made to a return after it has posted to the Master File. (1) Programs are managed in Endevor. (2) Change Tickets are required for program changes and are managed in IRWorks/Service Now. (3) All software changes are iSAT tested, reviewed, and documented in DocIT.

Command Code (CC) TRDBV

2.3.73.2 (12-31-2025) Command Code (CC) TRDBV TRDB stores the following tax return information submitted by the taxpayer: All electronically filed original tax return information submitted by the Individual filer through the legacy Electronic Filing System which includes ELF, ETD, Telefile, Digest and Online (i.e., Form 1040, Form 1040EZ, and Form 1040A and their associated forms and schedules for tax years 1998 through 2012.) See table below. All electronically filed original tax return information submitted by the Business filer through legacy EFS, ELF, EMS, Telefile and Magnetic Tape Processing (MGT). This includes Form 941, Form 1041, or Form 1065 Paper Parent Option, Form 9465 (Installment Agreements), Form 4868, and the associated forms and schedules for tax years 1998 through 2015. See table below. Note: Due to the retirement of legacy ELF, EFS, ETD, and EMS all subsequent electronically filed tax returns will be accepted in their entirety by MeF and stored on M-TRDB. Use RRD via EUP to access the data. TRDB will continue to store data as specified in IRM 2.3.73.2(1)(c) through (g). Corrections made to the tax return data in the Error Resolution System (ERS), Generalized Mainline Framework (GMF), and Generalized Unpostable Framework (GUF) as it is processed through the submission pipeline. Status (e.g., suspended, corrected, posted), Processing Codes (e.g., code and edit condition, notice, audit, resequence, unpostable) and history information as it is processed through the submission pipeline. A final status of 'Additional Tax Assessment' is recorded if an adjustment is made to a return after it has posted to the Master File. The adjustment is not stored on TRDB. All MeF and paper filed returns that are also found on the IMF and BMF Return Transaction Files (RTF) beginning with processing year 2003. These returns are input to TRDB after GMF perfection rather than from original taxpayer submitted data also known as T-lines. Only the portion of the return that is part of the GMF transaction will be present (RTF data). This is the initial phase of merging RTF On-Line with TRDB. RAL (Refund Anticipation Loan Code) appears as a 0, 1, 2, 3, 4 or 5 as follows. 0 - No Financial Product 1 - Pre-Refund Advance Product - Taxpayer charged an advance fee - Refund Anticipation Loan (RAL) 2 - Post-Refund Financial Product (Refund Transfer) - Refund Anticipation Check (RAC) 3 - Pre-Refund Advance Product - Taxpayer not charged an advance fee 4 - Other/New product - Not meeting the above criteria 5 - Text field to explain other/new product #4 Note: The bank product disbursement codes displayed on TRDBV are not the same as the RAL/RAC codes. For more information see IRM 21.4.1.5.7 Reject codes for tax returns that are rejected from MeF. Note: TRDB will continue processing transcribed fields for paper filed and MeF tax returns. The data can be accessed via CC TRDBV or TRDB transcript. CC Tax Return Data Base View (TRDBV) is a Command Code used by IDRS users to gain read-only access to the tax return data detailed above. The header portion of the TRDBV form data screen contains current data which can be the original submitted or updated tax account information (e.g., filing status, current status, input source). Additionally, original data will display on the left side of the TRDBV screen under the column 'Value'. The most recent correction will display on the furthest right side of the screen under the column 'Changed Value'. Beginning March 2004 Form 8453 paper signature document research will be available through TRDB Command Code R8453 (and paging command P8453). The Form 8453 DLN information has been included in the SSN submission level summary screen and in the return form level summary screen. There will be no ACCESS CODE or additional information beyond the 8453 DLN available through CC TRDBV. Use CC R8453 with the 8453 DLN if additional detail information is needed. Beginning January 2004 the entry code is no longer required for screen input. References to the entry code have been removed. Any references in this document to the entry code (EC) that remain are a reminder that the cursor must be placed at or after this point of input for the request to be properly captured. Beginning January 2004 Form 1120, Form 1120-S, Form 1120-POL, Form 990, Form 990EZ, Form 990PF series returns and Form 7004 and Form 8868 will be able to be filed electronically in an XML format through (MeF). Access to these electronically filed returns will not be through the traditional TRDBV Command Code view but instead will be viewed using a browser based graphical interface. Consult separately issued documentation for details. Additional information on Electronic Filing, Modernized Electronic Filing (MeF), and Modernized TRDB (M-TRDB) can be found in IRM 3.42, Electronic Tax Administration, (specifically sections 3.42.4 and 3.42.5). ELF filed Form 1065 for tax years 1999 through 2006 can be accessed using cc TRDBV. Use Employee User Portal to access Form 1065 data (including Schedule K1) for tax years 2007 and later submitted through MeF. TRDB will continue to store the transcribed portion as specified in IRM 2.3.73.2(1)(c) through (g). Note: Schedule K1 associated to an MeF or Paper-filed return (Form 1065, 1120-S, 1041) are not transcribed, therefore the Schedule K1 data will not be stored on TRDB, however if the return was received for tax year 2006 and prior through legacy ELF or EFS then Schedule K1 will be available on TRDB providing the record has not been purged. Beginning August 2009 Form 1040, FORM 1040A, FORM 1040EZ Series Returns were filed electronically in an XML format through MeF. They can be viewed using a web browser to access thru the Employee User Portal (EUP). TRDB will continue to receive paper filed Form 1040 Tax Returns and the transcribed portion filed through MeF. These forms will be available using command code TRDBV. In TY2010 (PY2011) the following tax forms were processed concurrently by MeF and legacy ELF: 1040, 1040(Sch A), 1040(Sch B), 1040(Sch C), 1040(Sch D), 1040(Sch E), 1040(Sch EIC), 1040(Sch M), 1040(Sch R), 1040(Sch SE), 1099R, 2106, 2210, 2441, 4562, 8283, 8812, 8829, 8863, 8880, 8888, and W-2. Retention Processing - The process to delete returns that have exceeded their record retention is scheduled annually. Returns that do not match CSED retention files provided by IMF and BMF will be removed from TRDB. Generally, returns are kept for seven years or possibly longer if there is an open CSED or other Master File criteria is present such as a balance due on the account. Once the return is deleted from TRDB it is no longer available and can not be restored especially if a TC 370 is input to restore the Master File module. The signature PIN will no longer be displayed on the TRDB transcript print or cc TRDBV. TRDB processed the final legacy ELF 1040 tax returns for TY2012. TRDB will no longer process legacy ETD forms beginning in TY2012 (PY2013). Prior year tax returns will remain on TRDB until they no longer meet the criteria to be retained. In TY2013 legacy Forms 1041 and 94X series tax returns were accepted through MeF and legacy concurrently. The complete MeF return is stored on M-TRDB which can be accessed using Return Request and Display (RRD) via Employee User Portal (EUP). Users can submit an OL5081 to request access. For more information about RRD see IRM 21.2.2.4.4.9 TRDB processed the final ELF legacy 94X tax returns for TY2015 (tax period 201503) and 1041 for TY2013. All subsequent electronically filed 94X and 1041 tax returns will be received by MeF and stored on M-TRDB. TRDB will continue to store data as specified in IRM 2.3.73.2(1)(c) through (g). TRDB transcripts (JRDB14) are no longer sent to the service center print rooms. The files are now available through Control-D. They can be sent to your local printer. For information on how to access Control-D see IRM 1.4.16.8.5(3). The table below (Tax Returns stored on TRDB and M-TRDB) lists the most common form types and tax years available on TRDB and M-TRDB. Paper and MeF tax return information is limited to transcribed fields and other data as specified in IRM 2.3.73.2(1)(c) through (g). The TRDB-DT-RCVD is the date the tax return was processed in TRDB. Prior year tax returns received during the current processing year will display the line numbers from the current year's tax return. The exception is when a prior year tax return is being updated such as an amended tax return. This is not a change. Forms 8995 and 8995-A have been combined into one form type 8995-8995A on the TRDBV screen displays and transcripts. Lines 3, 5, 7, 9, 12, 16, and 17 apply to Form 8995. Lines C2 (Schedule C, line 2), 27, 29, 31, 34, C6 (Schedule C, line 6), 38, and 40 apply to Form 8995-A. Some records may indicate an erroneous CURRENT-STATUS. Validation is recommended. Most TY2011 tax returns have been deleted from the TRDB database. Please check TRDBV. If there is no data available then it cannot be recovered. GUF Perfected Return (for PY2009 and prior this was status code 17). If any DLN is not resolved and closed within the same processing year as its DLN, the Current Status will display as default. 'SCAN is a new input source for scanned paper forms submitted via MeF.' Added Direct Deposit fields to the following Forms 706, 706-NA, 706-GSD, 706-GST, 709, 709-NA, 720, 940, 941, 943, 944, 945, 990-PF (8050), 990-T (8050), 1041, 1041-QFT, 1042, 1065, 1066, 1120, 1120-C, 1120-F, 1120-FSC, 1120-H, 1120-L, 1120-ND, 1120-POL (8050), 1120-PC, 1120-REIT, 1120-RIC, Form 1120-S, 1120-SF, 4720 (8050), 8752, 8288, 8804,5330 and CT-1 Added new Form 708 to the Form 7004 extension.

Command Code (CC) TRDBV General

2.3.73.2.1 (01-01-2021) Command Code (CC) TRDBV General The Input screen for Command Code TRDBV is displayed in Exhibit 2.3.73-1. TRDBV summary selection screens display the returns/schedules/forms submitted by a specific filer. Four levels of summary screens are possible when using CC TRDBV. Submission Level Selection Screen contains details of all tax returns that are stored on the TRDB that match the parameters of the TRDBV request. Exhibit 2.3.73-2. Form/Schedule and Processing Data Screen contains details for all of the forms/schedules submitted by the filer for a selected submission. Exhibit 2.3.73-3. This screen may also have the option of displaying additional screens for the following information: 1. Taxpayer Explanation (TXPYR-EXPL) 2. Paper Documents (PAPER-DOCS) 3. Status History (STAT-HIST) 4. SSN/EIN Validation (SSN-VALDN, EIN-VALDN) 5. Unallowables (UNALLOWBS) 6. Unprocessed Data (UNPRCSSBL) 7. Processing Codes (CODES) 8. Change History (CHANG-HIST) 9. Work History (WORK-HIST) 10. Election Statements (ELECTION) 11. Preparer/Taxpayer Notes (NOTES) 12. Electronic Postmark (POSTMARK) 13. TRDB Return Alert (INFO-ALERT) 14. Regulatory Explanations (REGULATORY) 15. Third Party Information (THIRDPARTY) 16. Electronic Signature (SIGNATURE) 17. ERO Signature Statement (ERO-INFO) 18. Disclosure Statement (CONSENT) 19. Unresolved GMF/ERS/MF/GUF Pipeline data (PIPELINE) 20 MeF Rejected (REJECTED) 21 MeF Business Rule Error (RULES) Form Group Level Selection Screen will be displayed if the taxpayer submitted more than one hundred of a particular form with their submission, i.e., SCH-K1. Exhibit 2.3.73-4. Form Occurrence Level Selection Screen will be displayed if the taxpayer submitted more than one of a particular form with their submission, i.e., W-2.Exhibit 2.3.73-5. The command code will automatically change to TRDPG when the first screen is displayed. TRDPG allows the users to page through the return data using enter only. No entry code is needed for TRDPG commands. However, when requesting a new SSN/EIN/DLN, TRDPG must be changed to the command code TRDBV. The access code allows the retrieval of the desired tax return information from the summary screens. Each screen will be assigned a range of valid access codes. To retrieve the desired tax return information, enter the access code from the list displayed on the screen. The following access codes can be used at any time after making a selection from the Submission Level Selection Screen: ZZ - Return to First Screen YQ - Batch Print Request - Specific Form YP - Batch Print Request - Entire Submission Note: A two digit screen number may be entered in the access code field to skip to that screen in a multiple screen display (i.e., 10 to skip to page 10 when viewing a Form 1040). When doing a query by tin without the MFT or tax year, TRDBV will display all the data found on a given record including a current or former spouse. If the account has been re-sequenced, please check the primary TIN. The TXPYR field on the TRDBV screen shows the P (primary) or S (secondary). If the re-sequenced record is a secondary account please enter the primary TIN, MFT and tax year for additional information. TRDB transcripts and TRDBV screen displays are updated yearly. Test data is available on Doc-it. Users not having access to Doc-it can open a P4 KISAM ticket and assign it to the TRDB group. Users with access should sign on and navigate to the home page. To the right of the project search box is a drop down menu, select Advanced Search (General). Type Transcripts in the contains box. Select docit and search for Folder(tad_folder). In the properties box select Project Name, contains and type TRDB. MeF Rejected Returns are tax returns submitted through MeF that were rejected because the business rules were not met. TRDBV displays the business rule number in the error description of form type Rules. DLN reuse - Every decade there is a possibility that a DLN can be recycled and assigned to a different taxpayer. When accessing TRDBV please be sure to validate the DLN against the taxpayer's TIN, MFT and tax period.

Command Code (CC) TRERS

2.3.73.3 (06-20-2018) Command Code (CC) TRERS Command Code TRERS is an extension of Command Code TRDBV developed specifically for ERS processing. TRERS functions exactly as TRDBV with the added ability to select a return based on the DLN of the latest GTREC command executed by the IDRS user without entering parameters for the TRERS command. The primary function of TRERS is to allow on line viewing of tax returns on TRDB from one IDRS session while executing GTREC commands from a second IDRS session. When working in ERS, TRERS replaces TRDBV as the initial command code for accessing tax returns stored on TRDB. This section will only address the initial execution of command code TRERS, you must also reference or be familiar with the subsequent paging command code TRDPG. All subsequent paging is handled via Command Code TRDPG and is documented under Command Code TRDBV. For further information on TRDB and TRDBVIRM 2.3.73.2. In addition to the following information on TRERS, the instructions for TRDBV apply to TRERS with the exception of the DLN/TIN field which is optional rather than required for TRERS. This is an effective manual fallback in case the ERS DLN cannot be automatically passed to TRDB.

Command Code (CC) TRERS General

2.3.73.3.1 (06-20-2018) Command Code (CC) TRERS General TRERS is executed with no parameters after a GTREC command has been executed from a separate IDRS session. TRERS will retrieve the return from TRDB based on the DLN associated with the GTREC command. The Input screen for Command Code TRERS with no parameters is displayed inExhibit 2.3.73-15. TRERS may also be used with any or all of the same parameters as Command Code TRDBV. The input screen for Command Code TRERS using parameters is displayed inExhibit 2.3.73-16. TRERS returns with the command code changed to TRDPG. The returned screen and all subsequent paging is described in more detail in Command Code TRDBV.IRM 2.3.73.2 Note: Command Code TRERS entered with a DLN or TIN may be used to access any return on TRDB. TRERS does not limit access to those returns in the ERS inventory.

Command Code (CC) TRERS Terminal Responses

2.3.73.3.2 (01-01-2021) Command Code (CC) TRERS Terminal Responses In addition to the terminal responses listed,IRM 2.3.73.2. the following terminal response is specific to Command Code TRERS. NO DLN FOUND FROM ERS COMMAND - INPUT DLN: TRERS failed to find a DLN from a GTREC command issued by the same IDRS user. This may be caused by submitting the TRERS command before a GTREC command or a system error. a. If the GTREC command was issued prior to the TRERS command or an error message was returned with the GTREC screen, notify your local IDRS help desk. The problem should be brought to the attention of ECC-MTB through ESD via KISAM ticket. TRERS may continue to be used, however, the DLN of the appropriate return must be entered until the problem is resolved. b. One of the following TRERS related error messages may be returned with the GTREC screen by the passoff command code TRERU if a system error occurs. Please include it with any notification performed in (a) above. Generic message: UNABLE TO FORWARD DLN TO TRDB VIA TRERU-CALL HELP DESK, followed by on of the following short specific messages: IHXFER STATUS 1 TIMEOUT IHXFER STATUS 2 ERROR IHXFER STATUS 3 NAP DOWN IHXFER STATUS 4 IBM ABEND IHXFER STATUS 5 MCC CICS IHXFER STATUS 6 DCC CICS TRDB STATUS ERROR 01 TRERU STATUS ERROR 1 TRERU STATUS ERROR 2 TRERU STATUS ERROR 3 TRERU STATUS ERROR 4

Command Code (CC) TRPRT

2.3.73.4 (06-20-2018) Command Code (CC) TRPRT When submitting a request with a large number of K-1s attached, please notify the TRDB programmers in advance. Command Code TRPRT is used for requesting a graphical (form image) print of a tax return stored on TRDB. These prints contain original taxpayer submitted data only, no corrections or processing codes. Use TRPRT for taxpayer requests for copies of legacy ELF tax returns. Requests for transcript prints should be made using command code TRDBV and access code YP. For further background information on TRDB IRM 2.3.73 TRPRT places the graphic print request in a queue which is processed overnight and shipped electronically based on the terminal id from which the request was made to the service center print system the following morning. TRPRT graphic print files (JRDB24) are no longer sent to the service center print rooms. The files are now available through Control-D. They can be sent to your local printer. For information on how to access Control-D see IRM 1.4.16.8.5(3). Command code TRPRT can only be used to request graphic prints for legacy ELF filed tax returns. Command code TRPRTT can be used to request transcript prints. A graphic print can not be created if the account information is not available. Check TRDBV before making a request for a graphic print.
