Error Reject Codes (ERCs) to Business Rules (BRs) Crosswalk

To assist in the transition from the current e-file to the Modernized e-File (MeF) system, we are providing a crosswalk of the Form 1040 family Error Reject Codes (ERCs) to Business Rules (BRs). The TY2011 crosswalk is included on the Tax Year 2011 Schema Page for Form 1040.
