Your return is due April 15, 2015.
If you cannot file on time, you can get an extension. You may use any federal extension provision for Wisconsin, even if you are filing your federal return by April 15.
How to get an extension You do not need to submit a request for an extension to the department prior to the time you file your Wisconsin return. When you file your Form 1 enclose either:
- a copy of your federal extension application (for example, Form 4868) or
- 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 15, 2015. This applies even though you may have an extension of time to file. If you do not file your return by April 15, 2015, or during an extension period, you are subject to 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 15, 2015. Submit the payment with a 2014 Wisconsin Form 1‑ES. You can get this form from our website at revenue.wi.gov or at any Department of Revenue office. (Exception You will not be charged interest during an extension period if (1) you served in support of Operation Iraqi Freedom 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 2, 2015, 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 spousesif married filing a joint return) from farming or fishing.
