§ 289A.40 — Limitations on Claims for Refund

Plain-Language Summary

You must file a claim for a tax refund within 3.5 years of filing your return, or within one year after the tax was paid, whichever is later. If you agreed to extend the assessment period, you have six months after the extension ends to file a refund claim. Special rules apply when federal changes affect your Minnesota return.

Practical Notes
If you discover you overpaid your taxes, act quickly. The 3.5-year deadline is firm and the state cannot issue a refund after it expires, even if you clearly overpaid. If the IRS changes your federal return, you have a limited time to file an amended Minnesota return to claim any resulting refund.
