The Wisconsin Department of Revenue (DOR) has updated its instructions to state 2020 income/franchise tax forms, explaining how to report Wisconsin differences from federal law as a result of the Consolidated Appropriations Act, 2021.
The instructions follow a DOR notice identifying significant provisions of the act that affect the filing of 2020 Wisconsin income/franchise tax returns. As of Jan. 22, there are no pending bills before Wisconsin's legislature that would change the tax treatment.
