Tax filing deadline extended
coronavirus covid-19 closed

WISCONSIN — Both federal and Wisconsin income tax payment and return due dates are automatically extended to July 15. Wisconsin law will automatically extend time and waive interest and penalties for taxpayers due to a presidentially declared disaster.    

Tax filers do not have to file any extension forms to be eligible for this new due date.

There is no limit on the amount of payment to be postponed, and there are no income exclusions.  

This applies to individuals, trusts, estates, partnerships, associations, companies or corporations. 

This relief is solely for income tax payments, estimated income tax payments and returns due April 15. 

There will be no interest or penalty for the period of April 15 to July 15.  

Interest, penalties, and underpayment interest for failure to make quarterly estimated tax payments with respect to such postponed federal income tax filings and payments will begin to accrue on July 16.
