About Property Taxes in Michigan
Michigan has one of the most distinctive property tax structures in the country — most homeowners receive two separate tax bills each year: a summer bill and a winter bill. The summer bill (covering school operating taxes and some local taxes) is issued July 1; the winter bill (covering county, township, and remaining local taxes) is issued December 1. Michigan property assessments are governed by Proposal A (1994), which caps the annual increase in "taxable value" at 5% or the rate of inflation (CPI), whichever is lower. This means long-term homeowners are often taxed on a value well below current market value. However, when a property sells, the taxable value "uncaps" and resets to 50% of the new market value — sometimes causing a significant tax increase for new buyers.
Payment & Assessment
Michigan property tax bills follow a split schedule: Summer tax bill: Issued July 1, due by September 14 without penalty. After September 14, a 1% monthly penalty applies for the first two months, then 1/2% per month thereafter. Unpaid summer taxes are turned over to the county treasurer on March 1. Winter tax bill: Issued December 1, due by February 14 without penalty. After February 14, similar penalties apply. Unpaid winter taxes are also turned over to the county treasurer. Some townships and cities collect only summer or only winter taxes — check with your local treasurer for your specific billing schedule. After taxes are turned over to the county treasurer (March 1 for prior-year summer taxes), additional fees apply and the county begins the forfeiture and foreclosure process if taxes remain unpaid for three years. Most counties and municipalities offer online payment. Contact your local township or city treasurer for payment options.
