How do I apply for an extension for my Wisconsin state taxes?

How To Get An Extension Of Time To File

Your return is due April 18, 2022.

If you cannot file on time, you can get an extension. You can use any federal extension provision for Wisconsin, even if you are filing your federal return by April 18.

How to get an extension

You do not need to submit a request for an extension to us prior to the time you file your Wisconsin return. When you file your Form 1 enclose either of the following:

• A copy of your federal extension application (for example, Form 4868)

• A statement indicating which federal extension provision you want to apply for Wisconsin (for example, the federal automatic 6-month extension provision)

Note You will owe interest on any tax that you have not paid by April 18, 2022. This applies even though you may have an extension of time to file. If you do not file your return by April 18, 2022, or during an extension period, you may have to pay additional interest and penalties. If you expect to owe tax with your return, you can avoid the 1% per month interest charge during the extension period by paying the tax by April 18, 2022. Submit the payment with a 2021 Wisconsin Form 1-ES. You can get this form at any Department of Revenue office or use our estimated income tax interactive voucher on our website. Use Form 1-ES to make an extension payment even if you will be filing your return electronically – do not use Form EPV. Exception: You will not be charged interest during an extension period if (1) you served in support of Operation Freedom’s Sentinel in the United States, (2) you qualify for a federal extension because of service in a combat zone or contingency operation, or (3) you qualify for a federal extension due to a federally-declared disaster.See Special Conditions below.

If you were a farmer or fisher and you did not make estimated tax payments, you must file your return and pay any tax due by March 1, 2022, to avoid paying interest for underpayment of estimated tax. Farmers and fishers are individuals who earn at least two-thirds of their gross income (gross income of both spouses if married filing a joint return) from farming or fishing.

Special Conditions A “Special Conditions” section is located to the right of the Filing Status section on page 1 of Form 1. If you have an extension of time to file due to service in support of Operation Freedom’s Sentinel in the United States, enter “01” in the Special Conditions box. If you qualify for an extension because of service in a combat zone or contingency operation, enter “02” in the box. If you qualify for an extension because of a federally-declared disaster, enter “03” in the box and indicate the specific disaster on the line provided.
