The Minnesota Department of Revenue audits tax returns to ensure accuracy.

We usually have 3½ years after a return is due or filed, whichever is later, to audit your return and send you a formal notice of any change in the amount of tax, penalty and interest you owe, or if we owe you a refund.

If your organization is being audited, you should have received an audit confirmation letter and “The audit process” fact sheet. If you have additional questions, call the phone number provided on your letter.
