How Michigan Property Tax Is Calculated
Annual tax = Taxable value × Total millage rate ÷ 1,000
One "mill" is $1 of tax for every $1,000 of taxable value. If your taxable value is $120,000 and your total millage is 32.5 mills, your annual tax is $120,000 × 32.5 ÷ 1,000 = $3,900. Your total millage is the sum of the rates levied by your county, city or township, school district, and any special authorities — it is printed on your summer and winter tax bills.
What If I Just Bought This Home?
When a Michigan home changes hands, its taxable value "uncaps" to the State Equalized Value (SEV) — about 50% of market value — in the year after the sale. That can mean a large jump from what the previous owner paid. If you enter the SEV above, the estimator shows your estimated tax after uncapping so there are no surprises.
Frequently Asked Questions
What is a mill in Michigan property tax?
A mill is $1 of tax per $1,000 of taxable value. A total millage rate of 32.5 mills means $32.50 per $1,000 of taxable value. Add up every levy on your tax bill — county, city/township, school district, library, and special authorities — to get your total.
Where do I find my millage rate?
On your summer (July) and winter (December) property tax bills from your city or township treasurer. The bill lists each taxing authority's rate and the total. You can also find it on your local assessor's or treasurer's website.
What is the difference between taxable value, assessed value, and SEV?
Assessed value is roughly 50% of your home's market value. State Equalized Value (SEV) is the assessed value after county and state equalization — usually the same number. Taxable value starts equal to SEV, then is capped by Proposal A: it can only grow by the lesser of 5% or inflation each year while you own the home. Your tax is calculated on taxable value, which is why it is often well below SEV for longtime owners.
What is the Principal Residence Exemption (PRE)?
If the home is your principal residence, the PRE (formerly the homestead exemption) exempts you from the 18-mill school operating tax. If you already claim it, your tax bill already reflects the lower millage — choose "Already reflected in my millage" above. If you have not claimed it, file the PRE affidavit with your local assessor; the estimator's "show PRE savings" option shows roughly how much the 18 mills are worth on your taxable value.
What happens to my taxes when I buy a Michigan home?
The taxable value uncaps to SEV in the year after the transfer. Example: the seller's taxable value was $90,000 but the SEV is $160,000 — your tax will be based on $160,000, not $90,000. Enter the SEV above to see the uncapped estimate before you close.
When are Michigan property taxes due?
Most Michigan owners get two bills: a summer bill (typically due in September) and a winter bill (typically due in February). Exact due dates and late penalties vary by city or township — check your bill or treasurer's site.
What is the Homestead Property Tax Credit?
Michigan offers a Homestead Property Tax Credit for qualifying lower-income homeowners and renters, claimed on form MI-1040CR with your state income tax return. It is a credit against your income tax, not a reduction of the property tax bill itself. This estimator does not model it.
How accurate is this estimate?
It is an estimate based on the two numbers you enter. Real bills can differ because of special assessments, delinquent charges, partial-year ownership, PRE status, and local fees. Use your actual tax bill for the exact amount. This tool does not set or look up your millage rate — millage varies by address, and only your bill or local treasurer has the authoritative figure.

Estimate only — not tax advice. This calculator multiplies the taxable value and millage rate you enter. It does not look up your millage rate, model special assessments, or account for credits, partial-year ownership, or delinquent charges. Consult your local assessor or treasurer, or a tax professional, for your exact bill.
