Program Scope and Objectives

CommandCode (CC) DDBCK is used for validating additional children and credits claimed on amended returns (1040X). This CC is maintained within the Dependent Database (DDB) project.

Purpose: This IRM section provides instructions for using the Integrated Data Retrieval System (IDRS) Command Codes DDBCK, DDBCV, and DDBCS.

Audience: Taxpayer Services (TS), Small Business Self-Employed (SB/SE), Large Business and International (LB&I), Tax Exempt and Government Entities (TE/GE) and Submission Processing (SP).

Policy Owner: Taxpayer Services (TS).

Program Owner: Taxpayer Services (TS).

Primary Stakeholders: Taxpayer Services (TS), Small Business Self-Employed (SB/SE), Large Business and International (LB&I), and Tax Exempt and Government Entities (TE/GE).

Program Goals: The primary use of these command codes are to aid in validating additional children and credits claimed on amended returns (1040X).

Exceptions & meaning →

Background

Additional claims for credits (child tax credit, EITC, child care credit, education credit) from amended returns and math error notices can be entered into CC DDBCK to have the changes checked against DDB rules. If issues are found, then CC DDBCK may instruct the user to send the case to exam. If the case does not meet exam criteria, account management can process the adjustment as usual.

The Dependent Database (DDB) is a rules-based selection application that is designed to identify questionable claims for refundable credits.

The sources of data displayed comes from filed returns on IRTF (CC RTVUE), DM1(CC INOLE) and IMF (CC IMFOL).

Command Code DDBCK / DDBCV /DDBCS

Command Code (CC) DDBCK/DDBCV/DDBCS is used for validating additional children and credits claimed on amended returns (1040X). Command code DDBCV is the view only version of DDBCK without the update capability. Command code DDBCS is a selection setup screen used to monitor and modify work plans day to day, week to week and site by site.

When DDBCK/DDBCV request is entered with the Primary TIN of a return, it displays the dependents & qualifying children from the original posted return or as last modified. By entering update request into DDBCK, a user can then modify the data to reflect changes from the submitted 1040X.

After transmitting changes entered on the update screen, DDBCK/DDBCV validates any new TIN against INOLE, DUPTIN database and Dependent Database (DDB) rules. Messages are then displayed on the screen when

If the TIN or Name Control does not match INOLE data

If child is deceased or does meet the age criteria to qualify for a credit

If DUPTIN database indicates a duplicate use of a TIN

If a DDB rule is broken

The DDBCK Validation Result Screen will instruct the user on how to proceed with the case. If the case does not meet exam criteria, account management can process the adjustment as usual, but if the case needs to be classified or meets exam criteria, it should be sent to exam.

The use of command code DDBCK has been restricted to Accounts Management, Examination and Submission Processing. No other function should be allowed access. Command code DDBCV has not been restricted. It can be used by all functions.

Command Code DDBCK Return Summary Screen

The DDBCK Return Update Screen shows the following information from the original return or as amended:

DLN, date and filing status of original return

The latest claim received date entered into DDBCK.

Filing status of original return and filing status as amended

TINs from the return, Name control, date of birth, date of death for each TIN and what credit was claimed for each TIN.

A ‘Y’ under a credit indicate that it was claimed on the original return. An ‘A’ indicates that it was later added and a 'D' indicates it was deleted.

If the TIN on the original return was invalid, ‘INVLD SSN’ will be displayed under the SSN/AMEND column, and if the name control was invalid, a ‘*’ will be displayed next to the name control. A 'x' in the credit field indicates that it was disallowed when the return was filed.

If the posted return is not found for the SSN entered, an error message will be displayed. If the SSN is a secondary or was merged, it may indicate another SSN to research.

Informational messages that is pertinent to the case may be displayed on the lower half of the screen. If the SSN has an open AIMS, math error, O freeze, or if the EITC recertification indicator is significant, a message will also be displayed on the screen.

Dates of prior claims received are listed under the claim received dates label. Users can view/change prior claims or add data for new claims using this part of the screen. New point and shoot fields has been placed on the revised summary screen. The command code will perform different actions depending on where the cursor is placed when the transmit key is pressed.

To add a new claim, enter the claim received date into the highlighted input date field. The date is automatically populated by the command code if the latest amended return date is available. Otherwise, 'YYYYMMDD' is displayed. Hit TRANSMIT when the cursor is on the 'ADD' field to initiate the add request. If the change is for the same claim previously entered, use the 'EDIT' option next to the previous entered record to edit the record instead of ADD.

If any prior claim was entered for this return (up to 4 with the latest first), they would be listed below the input date field. The claim received date and category code are listed for each record. To view a previous entry, move the cursor to the claim received date of the desired record and hit TRANSMIT to display the validation result screen for that record. To change or delete the most recent record entered, move the cursor to the 'EDIT' or 'DELETE' field on the screen and hit TRANSMIT.

If there is a L freeze or TC290 on the module, or if there is a 2/10 year EITC ban on the account or if the tax period is old, the input to the command code will be disabled. STOP will be displayed instead of the date entry field.

Exceptions & meaning →

Command Code DDBCK Return Update Screen

The DDBCK Return Update Screen is displayed when an add request or change request is entered from the summary screen. The input fields and fields that can be changed are highlighted on the screen.

The following fields should be entered as needed when entering changes:

If a SSN is added, or to correct invalid SSN/Name control, enter it into the SSN/AMEND & N/C field

To add a credit claimed, enter an ‘A’ under the EIC, Exemption/DEPD, CTC, CCC, EDCR, or ADPT CR field

To delete a credit previously claimed, enter a ‘D’ under the EIC, Exemption/DEPD, CTC, CCC, EDCR, or ADPT CR field

The additional EIC is claimed on the 1040X, enter it in the EIC field

The following input fields are required when entering changes:

Filing status amended

Category code (EICX, EICC, EICP or EICN)

Claim amount (net result of adjustment)

Schedule C indicator ('Y' if the claim includes schedule C changes, otherwise 'N'). If 'Y' is entered, a subsequent second screen will be displayed for entering additional information from the schedule C.

Once the changes are transmitted, the command code will validate the entered information. Should the age of an EITC qualifying child be over 19, it will ask whether the QC is a student or disabled and waits for user to reply before continuing.

Exceptions & meaning →

Command Code DDBCK Validation Result Screen

The DDBCK validation result screen is displayed after the changes entered in the DDBCK return update screen have been validated.

For each SSN that was added or changed, the result of the TIN/Name control check, date of birth, date of death and age check are displayed next to the date of birth on page 1 of the validation result screen.

The determination made by DDBCK for the case entered is displayed on Line 23 on the first screen. This message will let the user in Accounts Management know how to proceed next with the case. Depending on the message, the case will either be

OK to input ADJ54 The case does not meet exam criteria, and the adjustment should be processed using normal procedures.

Sent to exam (DDBCK SELECTED, REROUTE TO EITC) The case meets exam criteria and selected. DDBCK will automatically generate the AIMS opening request (via TC424) for the next posting cycle. The claim should not be processed.

Sent to classification (SEND AS CAT A) Send case to classification and not process the claim. AIMS will not generate on the case.

The status of the validation is also displayed (Validation completed, validation failed, etc.) On DDBCV, validation results are displayed for research purposes only, and the data will not be saved, nor will it send case to exam.

If the validation passes, and the case is not selected for exam or classification, DDBCK updates DUPTIN/DUPOL to reflect any changed that were entered. If the TIN or name control entered failed validation, DUPTIN will not be updated, Instead, the command code will send a prompt "PROCESS UPDATES (Y/N)?" and waits for the user to respond before continuing. If the validation error is caused by data entry error, the fields can be corrected. When corrections are made and retransmitted, DDBCK will validate the input again from the beginning. To go ahead and update DUPTIN anyway using the incorrect TIN (in case the TIN / name control cannot be corrected), enter a ‘Y’ in the response field and transmit.

Users can hit transmit from the first page of the validation result screen to go to a second page. The second page displays the money amounts entered from the return update screen plus additional details on which rules that fired and who they fired for.

Result of the FCR check, duplicate TIN use check, citizenship check, schedule C filter break and DDB rule breaks are listed on page 2 of the validation result screen.

Exceptions & meaning →

Command Code DDBCS Selection Setup Screen

The DDBCS selection setup screen is used by headquarters to monitor and modify the work plans, day to day, week to week and site by site.

Business rules that apply are as follows:

Route additional cases to any other campus that still has capacity (choose the one with the lowest inventory) if the return does not have Schedule C issue.

If the return has Schedule C issues, route additional cases to another SBSE campus that still has capacity.

Exceptions & meaning →
