Fax Minnesota Department of Revenue — Send Documents Securely
A state tax matter in Minnesota involves sensitive documents, so the way you fax them to Minnesota Department of Revenue matters as much as the number you send to. Minnesota Department of Revenue administers Minnesota's state taxes program and takes in documents for residents throughout the upper Midwest. This guide covers the secure way to send the documents plus how to reach the correct office.
Does Minnesota Department of Revenue accept a fax?
State tax filing and payment happen online for most people, but the revenue department still takes fax for specific things: a power-of-attorney authorization, a response to an audit or notice letter, installment-agreement paperwork, and certain forms the department names. Either way, do not assume fax works everywhere — check the agency's rules for your document first.
Finding the official fax number
The reliable way to reach Minnesota Department of Revenue by fax is to use the number the receiving office publishes today — on the form instructions or the request you got — and confirm it by phone, since department lines change.
