Individual Income Tax Audits

We’ll send you a letter explaining our findings. If we made any changes to your returns, we’ll explain them in your letter.

If you agree with any changes, review income tax returns filed for other tax years to check if there are similar errors on those returns. If you find errors, you must file amended returns for those years.

If you disagree with any changes, you may appeal our findings to either us or the Minnesota Tax Court. You must file your appeal within 60 days of our notice. For details, see Appealing an Audit.

We may audit your return within 3½ years after it is due or filed, whichever is later. We can extend this time limit in certain situations. There is no time limit for audits if you did not file a return that year.

If you have exhausted all other administrative remedies, you may contact the Taxpayer Rights Advocate. Contacting the Taxpayer Rights Advocate is not an appeal and will not extend your appeal period.
