ACT/DMI - The Automated Computation Tool is programmed to correctly compute both within module and net rate interest netting once the correct tax module data has been input. While the ACT/DMI software can perform interest netting computations, it is vital that the module information be correctly analyzed and entered into the program.COMPA and INTST are to be used ONLY when DMI is not available.COMPA - Use Definer D to compute interest on refund amount. The first date entered will be the date from which the interest is figured. The second date will be the date to which the interest is figured. Example: COMPAD and the line underneath is 04152023 01192024 4,627.63INTST - Used to compute interest and penalties on an outstanding balance (OBL). The date entered will be the date to which interest is figured. Example: INTST and the line underneath is 02 202304 01192024 WOLFRFUND - Used to generate IDRS refunds. TXMOD is a prerequisite to RFUND. Definer R is used to obtain the RFUND format. The posted name and address is automatically generated from the TIF. Verify they match the document receiving the refund.Line Numbers11 - 941 PY12 - 94116 - 942 PY21 - 943 PY22 - 94326 - 1042 PY27 - 104231 - 1041 PY32 - 104136 - 1065 PY37 - 106541 - 706 PY42 - 70645 - 706 GS (D)/GS(T)46 - 709 PY47 - 70951 - CT-1 PY52 - CT-156 - 940 PY57 - 94061 - 1120 PY62 - 112067 - 106690 - 945 PY91 - 945
