The Wisconsin Department of Revenue (DOR) has announced immediate help for small businesses on sales taxes in response to COVID-19. Small businesses can immediately request a one-month extension to file sales and use tax returns due March 31, 2020 until April 30, 2020 and due April 30, 2020 until June 1, 2020. The DOR will not assess late filing fees or penalties if sales and use tax returns are filed by April 30 or June 1. By law, payments are due March 31 and April 30 and 12% interest (lowered from 18%) will accrue beginning on the due date, unless the legislature changes the law to allow the DOR to waive interest. Extension requests should be sent to DORRegistration@wisconsin.gov.
