Abstract Code - The abstract code represents the three digit IRS number found on Form 720, Quarterly Federal Excise Tax Return. It is displayed on AIMS in the Activity Code field. When excise tax returns are examined and there is an adjustment to the amount reported under an abstract code, Item 15 on Form 5344, Examination Closing Record must be completed to update the Master File Abstract field. Each abstract code examined must be reflected in Item 404 on Form 5344. The code that is displayed on the AMDIS is the code used when the requisition was input and is not overlaid when a full database is received. See IRM 4.4.12.5.63, Item 404: Form 720. (L13-E37/P1-L7/SSIVL)

When establishing a return on AIMS, enter an estimated activity code on Form 5345-B , Examination Request non-ERCS Users or Form 5345-D, Examination Request - ERCS (Examination Returns Control System) Users. The opening record sent to AIMS from Master File will overlay the estimated Activity Code with the correct code. For Form 720 the Activity Code input on Form 5345-B or Form 5345-D will not be overlaid. The Activity Code generated by Master File should not be changed unless one of the exceptions to the rule below applies:
