Important!

Our systems, including My DOR, UCP, Business Lookup, and our Tax Rate Mobile App are currently down for critical maintenance. If you haven’t filed the August 2020 return yet, the due date has automatically been extended to October 2; there is no need to request the extension. If you have already filed, you do not need to do anything else. We will waive late filing penalties for businesses unable to file their return by September 25.

Our offices remain closed to the public due to the COVID-19 pandemic, but we can fully support you remotely. Visit our Contact page for options.
