Individual Income Tax Audits

field_block:node:page:body

The Minnesota Department of Revenue reviews (audits) income tax returns to make sure we’re collecting the right amount of tax. During an audit, we use the information we get from you and others.

What do I need to do if the department audits me? [+]

If we have enough information, we will correct problems or errors on your return.

In some cases, an auditor may contact you by mail to request further information by a certain deadline. If you need more time, you may work with the auditor. You may also need to set up an appointment with the auditor. You may have someone represent you during the audit process by completing and submitting Form REV184, Power of Attorney.

What if I do not provide the requested information? [+]

What happens after an audit? [+]

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, the letter will explain what you need to do. You should review income tax returns filed for other tax years to check if there are similar errors on those returns. If you find more 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 more information, see Appealing an Audit.

Is there a time limit to adjust my return? [+]

What if I am having trouble resolving a tax issue with the department? [+]
