COVID-19 Update - After complying with a request to close our office to help slow the spread of COVID-19, our office is again open. We ask all clients who visit our office to wear a facial mask to prevent the spread of the virus.   

The Internal Revenue Service announced that all income tax returns that were due April 15, 2020 and May 15, 2020 will now be due July 15, 2020 because of the COVID-19 outbreak.  This new deadline also applies to the payment of 2019 income taxes (including extension payments) and 1st quarter 2020 estimated income tax payments. Minnesota changed its income tax filing deadline to conform with the July 15 federal deadline. However, Minnesota requires all income tax payments to be made according to the regular deadlines.
