Press Release

Tax Deadline is Monday, May 17, at Midnight


By - May 14th, 2021 03:42 pm

Wisconsin’s tax season was extended to May 17 this year due to COVID-19. To date, 2.85 million tax filers submitted returns out of an expected 3 million, and the average refund year to date is $793, up from $719 at this point last year.

Taxpayers can file an extension request with the IRS if they won’t make the May 17 deadline.

  • Request an extension from the Internal Revenue Service (IRS) by May 17 to avoid late filing penalties.
  • Go to the IRS website at www.irs.gov and search “extension” for more information. Taxpayers who file an extension request with the IRS automatically receive an extension from the state.
  • Keep a copy of the IRS federal extension application (Form 4868) for your records. Please keep in mind that even if you have an extension of time to file your return, you will owe interest on any tax not paid by May 17.
  • Avoid interest charges during the extension period by paying any estimated amount owed by May 17, using a 2020 Wisconsin Estimated Tax Voucher.

People may use the free, fast and accurate Wisconsin e-file online tool to file their state income taxes, or they may choose to use third-party software from an approved vendor. Like other online tools, Wisconsin e-file does the required math to prevent errors and allows direct deposit or withdrawal from a bank account. DOR encourages electronic filing for security reasons and faster refunds. So far, 93% of taxpayers have filed electronically.

DOR encourages taxpayers with questions to submit them online or call DOR’s individual customer service line at (608) 266-2486.
