Michigan homebuyer tax calculator
The first mortgage payment after closing is not always the payment you keep. Your early payment may be based on the seller's old tax bill. After the home sells, Michigan Taxable Value can reset. When the new tax bill reaches your lender, the escrow part of your payment — the money set aside for taxes and insurance — can rise too.
Use this calculator before you close to estimate your first full-year property tax bill as the buyer, using official local tax rates for the city, township, village, county, and school district.

Loading statewide 2025 tax rates...
This should only take a moment.
Step 1
Pick the county, city or township, and school district. We use the official 2025 tax rates published by Michigan Treasury.
Step 2
The home's purchase price and the seller's current Taxable Value are what we use to estimate the jump. The bigger the gap between those two numbers, the bigger the surprise on the next tax bill.
Step 3
We show what the seller pays now, what your bill will look like after Michigan's tax reset, and the difference per year and per month.
Example answer: if a home sells for $420,000 and the buyer's Taxable Value rises from about $158,000 to about $210,000, a 40-mill rate adds about $2,000 per year, or about $170 per month.
Where to look
These are sample layouts, not real documents. They show what to look for when you pull up the property record, your tax bill, or your closing paperwork.
Assessor record
The seller's current Taxable Value is the best number for estimating what they pay now.
On BS&A or an assessor site, Taxable Value is often close to SEV, but not always.
Tax bill
Look for whether the seller had the Principal Residence Exemption, also called PRE.
If the seller did not have PRE, their bill may use the higher non-homestead rate.
After closing
The pop-up usually hits the first calendar year after transfer, not always right away.
Your lender may adjust escrow after the new tax bill or escrow review.
In Michigan, property taxes are based on Taxable Value, not the price you paid for the home.
While one owner keeps a home, Proposal A limits how fast that Taxable Value can rise each year. But when the home sells, that limit usually comes off. This is called uncapping.
That means the buyer's Taxable Value can reset higher than the seller's. The tax jump often does not hit right away. It usually shows up later, when the new tax bill reaches the lender and the escrow part of the mortgage payment is recalculated.
Simple example
Imagine you buy a Michigan home for $420,000. At closing, your lender may estimate escrow using the seller's current tax bill, so the monthly payment can look normal at first.
The seller bought the home years ago for $260,000. At that time, the home's Taxable Value started around $130,000.
Over time, the home's market value rose. But because Proposal A limits how fast Taxable Value can grow each year, the seller's Taxable Value might still only be about $158,000.
After your purchase, Michigan can reset the buyer's Taxable Value closer to State Equalized Value, or SEV. SEV is often about half of market value, so on a $420,000 sale that could mean a Taxable Value near $210,000.
Now the tax bill may be calculated on about $210,000 instead of the seller's $158,000. That is the pop-up.
At a 40-mill tax rate, that difference can add about $2,000 per year to the tax bill, or roughly $170 per month.
You may not feel that right at closing. The surprise often comes later, after the new tax bill reaches the lender, the lender reviews escrow, and your monthly payment is raised to collect enough for future tax bills.
The result is that a buyer's first full-year tax bill can be much higher than the seller's, especially when the seller owned the home for a long time.
That is why buyers can get caught off guard. The payment they start with after closing may not be the payment they keep. Months later, once the lender adjusts escrow for the higher tax bill, the monthly mortgage payment can rise.
This calculator helps estimate that difference before it becomes part of your budget.

Money and taxes
Most Michigan property owners get separate summer and winter tax bills, with local rules deciding what lands on each bill.

Michigan township buyers should check for special assessments that can add separate road, sewer, water, lighting, sidewalk, or drain charges.

Michigan village residents usually pay village property taxes on top of township taxes, so the village boundary can change a buyer's total rate.

The calculator uses official statewide millage reports, then turns the math into a plain-English planning estimate.
Use this carefully: Michigan Porch uses the statewide published rates as a planning aid. The local assessor or treasurer controls parcel-specific values, due dates, and special assessments.
No. It is a strong estimate based on Michigan's published 2025 tax rates for your area. Your actual bill depends on what the local assessor decides your home is worth, called the SEV. Use this to plan your budget, not to lock in an exact figure.
The first calendar year after you close. Close in June 2026, and the seller's tax bill usually comes through for 2026. Your new popped-up bill arrives in 2027.
PRE is Michigan's primary-home tax break. If you own the home and live there as your main home, it can remove up to 18 mills of local school operating tax from the bill. Rentals, vacation homes, and second homes do not get it. File Form 2368 with the local assessor by June 1 for the summer bill or November 1 for the winter bill.
Mills are the tax rate. One mill means $1 of tax for every $1,000 of Taxable Value. A 40-mill rate means about $40 per $1,000 of Taxable Value. Different areas have different rates because county, city or township, school, library, public safety, parks, and other local taxes are stacked together.
It is the yearly number Michigan uses to cap Taxable Value increases while the same owner keeps the home. Think of it as the speed limit for Taxable Value. For the 2026 tax year, the multiplier is 1.027, or 2.7%. When a home sells, that cap usually resets.
A few, mostly family transfers. Parent to child, spouse to spouse, sibling to sibling, and some grandparent transfers may avoid the reset if the home stays residential. For family transfers, talk to a Michigan real estate attorney.
Most tax history pages show what the current owner paid. That is often based on a protected, lower taxable value. This calculator estimates what your taxable value becomes after Michigan's uncapping rule.
