Section 205.30 - Credit or refund; interest(1) The department shall credit or refund an overpayment of taxes; taxes, penalties, and interest erroneously assessed and collected; and taxes, penalties, and interest that are found unjustly assessed, excessive in amount, or wrongfully collected with interest at the rate calculated under section 23 for deficiencies in tax payments.(2) A taxpayer who paid a tax that the taxpayer claims is not due may petition the department for refund of the amount paid within the time period specified as the statute of limitations in section 27a.

If the department agrees the claim is valid, the amount of overpayment, penalties, and interest shall be first applied to any known liability as provided in section 30a, and the excess, if any, shall be refunded to the taxpayer or credited, at the taxpayer's request, against any current or subsequent tax liability.
