§ 289A.56 — Interest on Overpayments

Plain-Language Summary

When the state owes a taxpayer a refund, the state must pay interest on the overpayment. Interest begins to accrue after a specified period following the filing of the return or the due date, whichever is later. The interest rate is the same rate used when taxpayers owe money to the state.

Practical Notes
The state does not begin paying interest on refunds immediately. There is typically a processing period during which no interest accrues. If you are owed a large refund, filing early ensures you receive any applicable interest sooner. The interest rate mirrors what the state charges on underpayments.
