Wisconsin State Tax Extensions: Business, Personal, Information and Nonprofit Tax Returns

How do I get automatic business tax extension of time for Wisconsin?

Any extension of time granted by federal law or by the IRS for filing a federal corporation income tax return or exempt organization business income tax return automatically extends the time for filing the corresponding Wisconsin return. A federal extension form 7004 extends the due date of the Wisconsin return to 30 days after the extended due date of the federal return, regardless of when the federal return is actually filed.

If a corporation is not requesting an extension of time to file its federal return, but needs additional time to file its Wisconsin return, Wisconsin law provides an automatic extension of 7 months after the original Wisconsin due date or until the original due date of the corporation's federal return,whichever is later.

Does Wisconsin permit filing of consolidated return ?

The parent corporation of an affiliated group of corporations may file a consolidated federal corporation income tax return and obtain an extension of time to file the consolidated federal return. Wisconsin does not permit the filing of a consolidated return, but requires the filing of a combined return by corporations in a commonly controlled group engaged in a unitary business.

Tax payments

It is not necessary to pay the Wisconsin tax ("tax" includes economic development surcharge) that is estimated to be due in order to receive an extension of time to file the franchise or income tax return or the nonresident combined income tax return (Form 1CNS). However, an extension of time to file is not an extension of time to pay the tax. Tax not paid by the original due date of the return is subject to interest.

Interest:

Interest during the extension period is 1% per month, except that if the net tax due shown on a corporation franchise or income tax return is $500 or more, interest of 1% per month applies to only 10% of the tax due, and interest of 1.5% per month applies to the balance (this does not apply to Form 1CNS).

Exception: Interest will not be charged if the corporation qualifies for a federal extension due to a federally-declared disaster.
Interest during the extension period can be avoided by paying the taxes that are estimated to be due by the original due date of the tax return (if the actual tax due exceeds the estimate,the balance is subject to interest). Form 4-ES,"Wisconsin Corporation Estimated Tax Voucher," Form PW-ES, "Wisconsin Pass-Through Entity Withholding Estimated Payment Voucher," and/or My Tax Account should be used to make these estimated tax payments. If using a voucher, be sure it is for the same year as the tax return.

Are extensions available if I can't file my Wisconsin return by the due date?

Individual income tax return must be filed by April 15, 2021 , unless you have an extension of time to file.
The following extension of time to file options are available:

• Extensions available under federal law may be used for Wisconsin purposes, even if you do not need a federal extension because you filed your federal return by April 15, 2021. To obtain an extension only for Wisconsin, you must attach a statement to your Wisconsin income tax return indicating you wish to take the federal Form 4868 extension provision or attach a copy of the federal Form 4868 Application for Automatic Extension of Time to File U.S. Individual Income Tax Return, with only the name, address, and signature areas completed.


• If you have an extension for filing your federal return, this automatically gives you a 6-month Wisconsin extension, provided you attach a copy of your federal extension application to your Wisconsin income tax return.


• If you are allowed an automatic 2-month extension for filing your federal return because you are outside the United States and Puerto Rico on April 15, 2021, this automatically gives you a Wisconsin extension. Attach a statement to your Wisconsin return explaining how you qualify.

If I have an extension, will this extend the time to pay any tax due?

Even though you may have an extension of time to file your return, you will owe interest on any tax not paid by April 15, 2021. Returns not filed by April 15, 2021 or during an extension period, are subject to additional interest and penalties. If you expect to owe additional tax, you can avoid the 1% per month interest charge during the extension period by paying the tax you will owe by April 15, 2021. Submit the payment with a Wisconsin Estimated Tax Voucher.

You will not be charged interest during an extension period if:

• Operation Iraqi Freedom in the United States, or
• You qualify for a federal extension because of service in a combat zone, or
• You qualify for a federal extension due to a federally-declared disaster.

Penalty and Interest Charges on Tax Owed:

In all cases, interest will be charged at a rate of 1% per month from the date the tax should have been paid (April 15, 2024) until the date of payment. In addition, the state may assess the following penalties:

Late Payment Penalty

Wisconsin may also assess additional late payment penalties at a rate of 18% per year on the outstanding balance if you do not pay the total tax due by August 15, 2024.
