Property Tax Assessment in Shiawassee County

Property in Shiawassee County is assessed as of December 31 each year under MCL 211.30. Township and city assessors set values for each parcel, and the Equalization Department reviews those values to ensure they hit the 50% true cash value target. Assessment change notices go out each February. Owners who receive a notice showing a significant change should review it and contact their township assessor if they have questions.

Michigan's taxable value cap keeps taxes from rising too fast for existing owners. The cap limits annual increases to the rate of inflation or 5%, whichever is lower. When property sells, the cap lifts in the following tax year and taxable value resets to equal the assessed value. Buyers coming into Shiawassee County should use the Michigan Property Tax Estimator to gauge what taxes will look like after the cap resets. Details on how state assessment rules work are also available at Michigan Treasury property tax.

Appealing Your Shiawassee County Assessment

Shiawassee County property owners who disagree with their assessed value can appeal it. The process starts with the March Board of Review at the township level. You must file a written protest or appear in person before the Board's deadline. Supporting evidence matters. A recent licensed appraisal or comparable sales data from similar properties in the area strengthens your case. The Board can reduce your assessed value if your evidence supports it.

If the Board of Review does not settle the matter, you can petition the Michigan Tax Tribunal. The MTT hears property tax disputes from owners across the state. Residential property appeals must be filed by July 31. Commercial appeals are due by May 31. The MTT can be reached at 517-335-9760. The Property Taxpayer's Bill of Rights, MCL 205.735, lays out your rights throughout the process.

Shiawassee County Property Tax Payments

Treasurer Thomas W. Lewis collects delinquent property taxes for Shiawassee County after local townships forward unpaid amounts each year. Summer taxes are typically due in September and winter taxes in February. Exact deadlines vary by township. Contact your local township treasurer for the specific dates that apply to your parcel.

After taxes become delinquent and transfer to the county, interest and fees begin to accrue. The Treasurer handles payment plans and manages the forfeiture and foreclosure process for long-standing unpaid taxes. Call Treasurer Lewis at 989-743-2212 to discuss payment options or set up an arrangement. Paying delinquent taxes as early as possible limits the total amount owed and keeps the property out of the foreclosure pipeline.

Note: Michigan's property foreclosure process has firm deadlines. Taxes unpaid for three or more years can lead to county foreclosure, so do not let delinquencies go unaddressed.
