Michigan Compiled Laws, Chapter 141. Municipal Financing § 141.683

Sec. 83. (1) Interest or a penalty shall not be imposed on an additional tax assessment if, within 90 days from final determination of a federal tax liability which also affects the computation of the taxpayer's city income tax liability, the taxpayer prepares and files an amended city income tax return showing income subject to the city tax based upon the final determination of federal income tax liability, and pays the additional tax shown due thereon or makes claim for refund of an overpayment. Interest shall not be allowed on a refund of the city income tax resulting from a final determination of federal tax liability.

(2) Interest and a penalty shall not be imposed for underestimating the tax if the total amount of tax withheld and paid by declaration, equals at least 70% or more of the tax shown due on the final return or 70% or more of the tax shown on the taxpayer's return for the preceding taxable year.

(3) An employee shall not be penalized because of the failure of his employer to report or pay tax withheld from the employee when the employer has in fact withheld the proper amount of tax.
