Less than a week remains to file income tax returns, and the Wisconsin Department of Revenue (DOR) recommends that taxpayers not wait until the last minute to file. Returns must be received or postmarked by midnight on Monday, April 15.
“We process around three million returns annually,” notes Department of Revenue Secretary Peter Barca. “Around a half million returns came in the last two weeks. Our season total now stands at 2.3 million, so activity has been brisk. We’re anticipating another half million taxpayers to file in the remaining days, and we expect the rest will likely file for extension.”

- File an extension request with the IRS if you won’t make the April 15 deadline. You must request an extension from the Internal Revenue Service (IRS) by April 15 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 April 15. You can avoid interest charges during the extension period by paying any estimated amount owed by April 15, using a 2018 Wisconsin Estimated Tax Voucher.
