The Wisconsin Department of Revenue has announced that 2020 state individual income tax return filing and payment due dates are extended to May 17, 2021, in conformity with the federal income tax filing and payment due date automatic extension announced by the IRS on March 17. Wisconsin law provides for an extension of time and waiver of interest and penalties when the IRS extends filing deadlines during a presidentially-declared disaster. Individual taxpayers do not have to file any extension forms to be eligible for this new due date. No interest or penalties will accrue during the period of April 15, 2021 to May 17, 2021; interest and late filing fees will apply beginning May 18, 2021. No underpayment interest will apply for failure to make quarterly estimated individual income tax payments for the 2020 tax year. This relief does not extend to 2021 estimated tax payments for individuals, the first payment of which is due April 15, 2021.
