The Principal Residence Exemption (PRE) exempts your primary home from the 18-mill school operating tax. You must own and occupy the property as your principal residence by June 1 or November 1. You cannot claim PRE on more than one property.

Summer taxes are typically due September 14; winter taxes are due February 14. Some townships may differ slightly. Penalties and interest accrue after the due date.

Yes — appeal to the local Board of Review in March. If denied, appeal to the Michigan Tax Tribunal. Appeals succeed when comparable sales show your SEV exceeds 50% of market value.

Proposal A (1994) capped annual taxable value increases at the lesser of 5% or the Consumer Price Index (CPI). This means long-time homeowners often pay taxes on a taxable value far below current market value. When the property sells, the taxable value "uncaps" to the SEV (50% of market value) in the following tax year — this can cause a 20–50%+ tax increase for the new owner in year one.

Yes. Michigan offers the Poverty Exemption for low-income homeowners (income and asset tested, determined by local assessor). Veterans with service-connected disabilities may qualify for up to 100% exemption. Senior citizens may qualify for the Homestead Property Tax Credit on their state income tax return. Agricultural properties may qualify for the PA 116 or farmland preservation programs.

Your annual Notice of Assessment mailed each February shows both values. You can also look up your property on your county or township's online property tax portal — most Michigan counties have publicly searchable databases. Your mortgage statement's escrow section also shows the annual property tax collected. The Michigan Treasury's Equalization Division website lists resources by county.
