Michigan Property Tax Calculator
The year after a Michigan home sells, its taxable value resets, so the seller's tax bill is not your tax bill. Enter the address and the calculator finds the property's exact published millage, then works out the number to plan for the way Samantha does.

Estimate your Michigan property tax after you buy
The year after a Michigan home sells, its taxable value resets, so the seller's tax bill is not your tax bill. This works out a planning number the way Samantha does: half the price you pay, times the property's millage, divided by 1,000. The address is used only to find the property's city or township and school district through the U.S. Census Bureau's public lookup, and it is not stored. Nothing else you enter is sent anywhere.
Or choose the community
Enter a price and an address (or a community) to see the planning number.

Have Samantha check the propertyA planning estimate from the numbers you entered and the 2025 millage Michigan Treasury publishes for each city or township, school district and village. Rates can change each year when levies are voted or renewed. Michigan resets taxable value to half of the assessor's market value, which can be lower than the price you pay, so planning with the price errs on the high side. The real bill also depends on special assessments and on filing the Principal Residence Exemption. Place figures: Align Lending's 2026 Uncapping Study. Not a quote or a loan offer.

How the reset works
Three things set a Michigan buyer's tax bill
The cap comes off
In Michigan, a home's taxable value is capped while one owner holds it. The year after it sells, that cap comes off and taxable value resets to the state equalized value, which is half of the assessor's estimate of market value, not automatically half of what you paid.
Millage turns value into a bill
A mill is one dollar of property tax for every $1,000 of taxable value, and your millage rate is the total of the mills levied by your city or township, county, school district and other local units. Rates differ a lot between neighboring communities.
The exemption is yours to file
Michigan's Principal Residence Exemption lowers the tax on the home you live in by exempting it from up to 18 mills of local school operating tax. It does not carry over from the seller. A buyer files their own affidavit with the local assessor.
Why Samantha plans high
Her rule: never borrow somebody else's tax bill
Not artificially cheaper
“I don't want to make a house look artificially cheaper because I used the seller's old tax bill.”
Higher is the better surprise
“I'd much rather somebody ask me, 'Why are your taxes higher than what I'm seeing online?' than have them build a housing budget around the wrong assumption.”
The property decides
“I wouldn't tell somebody, 'You're in Oakland County, so here's what your taxes are.' It doesn't work like that. We need the actual property.”
Questions about Michigan property tax after you buy
If yours is not here, send Samantha the address and she will run the property's own numbers.
When does the higher tax start?
The reset happens the year after the sale, so it shows up in that year’s summer and winter bills. The bills in the year you buy are still figured on the seller’s taxable value.
Why does the calculator use half of the price I pay?
Michigan resets taxable value to the state equalized value, which is half of the assessor’s estimate of market value, not automatically half of what you paid. The assessor’s value can be lower than your price, so planning with the price errs on the high side, which is how Samantha prefers to plan.
Where do the millage rates come from?
From Michigan Treasury’s published total millage rates for every city or township, school district and village. Enter the property’s address and the calculator finds its city or township, school district and village through the U.S. Census Bureau’s public address lookup, then uses Treasury’s rate for exactly that combination. The address is not stored. Without an address, choose the community and the school district, or let it plan with the highest rate in the community. Rates can change each year when levies are voted or renewed, and the property’s own tax bill shows its exact rate, including any special assessments.
What if the home will be a second home or a rental?
The Principal Residence Exemption only applies to the home you live in. Without it, up to 18 mills of local school operating tax apply. When the calculator has the property’s district, it uses Treasury’s published non-homestead rate; when you type a rate yourself, it adds the full 18 to plan high.
Is the Principal Residence Exemption automatic?
No. The seller’s exemption does not carry over. File your own affidavit with the local assessor after you buy: by June 1 for that year’s summer and winter bills, or by November 1 for the winter bill.
How does a higher tax bill change my mortgage payment?
If your loan has an escrow account, your servicer pays the tax bills from it. Once a year the servicer reviews the account, which is where a higher Michigan tax bill after a purchase shows up as a higher payment. Planning with the reset number from the start avoids that surprise.
