What actually sets Michigan apart
The uncapping rule makes Michigan one of the clearest cases where the seller's bill is worthless as a guide. A home held for twenty years may have a taxable value far below half its market value, and the January after your purchase it resets. Ask the assessor what the uncapped taxable value will be, and budget from that.

What the Michigan rate leaves out
Michigan is 15th of the fifty by rate and 21st by the bill a median-value owner receives — a shift of 6 places, and the $217,600 median home value is what causes it. The rate is a reasonable shorthand here, but it is not the whole answer, and both numbers are worth checking before comparing Michigan with anywhere else.
How Michigan works out what you owe
Every property carries two numbers: state equalized value, which is half of market value, and taxable value, which is what the millage is actually applied to.
Proposal A caps annual growth in taxable value at 5% or the rate of inflation, whichever is lower. When the property is sold the taxable value uncaps and resets to the state equalized value.
Exemptions Michigan homeowners should claim
Each of these reduces a Michigan bill every year you hold the property, and almost none are granted without a claim:
- Principal Residence Exemption: Exempts an owner-occupied home from the school operating millage, worth 18 mills. It is the single largest reduction available to a Michigan homeowner.
- Disabled veterans exemption: A full exemption from property tax on the homestead of a veteran with a total service-connected disability, or an unremarried surviving spouse.
Where you buy inside Michigan changes the bill
A statewide average hides its extremes. Where they show up in Michigan:
- Wayne County: Detroit and its inner suburbs, where high millage on low values produces some of the highest effective rates in the country
- Oakland County: the affluent northern suburbs, with large differences in millage between school districts
- Kent County: Grand Rapids, where a fast-appreciating market has widened the gap between capped owners and new buyers
Michigan and its neighbours
The same $217,600 — the Michigan median — taxed at each neighbouring state's average rate:
- Ohio at 1.36%: about $2,959 a year, roughly $164 more than the $2,795 a Michigan owner would pay on the same value.
- Indiana at 0.74%: about $1,610 a year, roughly $1,185 less than the $2,795 a Michigan owner would pay on the same value.
- Wisconsin at 1.51%: about $3,286 a year, roughly $491 more than the $2,795 a Michigan owner would pay on the same value.
Appealing a Michigan assessment
If the assessed value on your Michigan home overstates what it is worth, the route is an appeal to the March Board of Review, then the Michigan Tax Tribunal. The window is the Board of Review sits for a short period in March each year, and it is strict — missing it means waiting a full cycle.
Frequently asked questions
When are Michigan property taxes due, and when must exemption claims be filed?
Most communities issue a summer bill on 1 July and a winter bill on 1 December. The Principal Residence Exemption affidavit is filed with the local assessor and must be on file by 1 June to apply to the summer levy.
Does this calculator use my exact Michigan county tax rate?
No — it applies the Michigan statewide average of 1.28%. Rates are set locally, and the spread inside Michigan is wide enough to matter: on a $217,600 home, $641 a year separates Michigan from an averagely taxed state before any county variation is counted. Check the parcel's own rate with its Michigan county before relying on this figure.

How this estimate is built
Principal and interest come from the standard amortization formula, worked through in full on the formula reference page. Property tax, insurance, PMI and loan-program figures layer on top from published assumptions — each one sourced, dated and listed on the methodology page. Every result here is an estimate built from public data, not a quote: confirm the specifics with a lender before relying on it.
