The single most common closing-day surprise in Michigan: your property tax bill won't match the seller's. Here's why that happens, how Proposal A's cap really works, and how to know your true number before you ever write an offer.
Two of these protect you while you own. The other two kick in the moment a home changes hands.
Figures from the Michigan Department of Treasury and State Tax Commission, 2026. Your exact bill depends on your city's millage and your home's assessed value — I run your real future number before you write an offer.
When you tour a home and the listing shows $2,400 in annual taxes, that number is almost a fiction for you as the buyer. It reflects what the current owner pays — a figure that's been artificially held down for as long as they've owned the place. The day you buy, that protection disappears and your bill is recalculated from scratch. Understanding that one mechanic will save you from the most common sticker shock in Michigan real estate.
Michigan voters passed Proposal A in 1994 to stop property taxes from ballooning every time the market jumped. The rule: while a single owner holds a home, its taxable value can only rise each year by the lower of 5% or the state's inflation rate multiplier. Over a decade of ownership, a home's market value might double while its taxable value creeps up slowly — which is exactly why long-time owners often pay surprisingly little.
For 2026, the State Tax Commission set that inflation rate multiplier at 2.7% (a factor of 1.027) — a notable drop from the 5% cap that applied in both 2024 and 2025. So a homeowner who didn't sell in 2025 sees their 2026 taxable value rise just 2.7%.
That cap is tied to ownership, not to the house. The year after a home sells, its taxable value uncaps — it snaps up to the State Equalized Value (SEV), which is roughly 50% of the home's true cash (market) value. For a home that's been in one family for years, that reset can push the taxable value up substantially in a single jump. Agents and assessors call it the "pop-up tax."
Michigan defines "transfer of ownership" broadly under Section 211.27a: a deed, a land contract, certain long leases, many trust transfers, a foreclosure, or a tax-deed sale. For a typical purchase, the practical takeaway is simple — buy a home this year, and its taxable value uncaps for next year's bill.
Here's the mechanic with round, illustrative numbers. Buy a home for about $250,000 and its SEV lands near $125,000 — so your taxable value uncaps to roughly $125,000 for the following year. If the previous owner's capped taxable value had been sitting near $80,000 (common for a long-held home), your taxable base is more than 50% higher than theirs the day you take title. Your bill rises in direct proportion, because Michigan taxes are simply taxable value × local millage. Wayne County's effective property tax rate runs around 1.31% of value — higher than the statewide median near 1.05% — so the city you buy in matters too. Your real figures live on each city guide; I run the exact number for any specific home before you offer.
After closing, the new owner must file Form 2766 (L-4260) with the local assessor within 45 days. Miss it and you can be hit with back taxes, interest, and penalties dating to the original due date. If your purchase qualifies for a family exemption — a transfer between spouse, parent, child, sibling, or grandchild for non-commercial use — this is also where you document it to keep the value capped. The form was revised in 2025 to require more detail on that relationship.
Ignore the listing's tax line. Estimate taxable value near half the price, apply the local millage, and know the number before you offer — not at closing.
Buyers who understand uncapping write cleaner offers. Being upfront about the future bill keeps deals from wobbling during financing.
Passing a home to a spouse, child, or grandchild can avoid uncapping entirely — but only if it's documented correctly and isn't used commercially.
Under Proposal A of 1994, a home's taxable value can only rise a little each year while one owner holds it — the lower of 5% or the annual inflation rate multiplier. When the home sells, that protection ends: the taxable value 'uncaps' and resets to the State Equalized Value (about 50% of market value) the following tax year. That reset is why your first-year bill is usually higher than the seller's.
While you own and occupy the home, its taxable value can increase by no more than the inflation rate multiplier or 5%, whichever is lower. For 2026 the Michigan State Tax Commission set the inflation rate multiplier at 2.7% (a factor of 1.027), down from the 5% ceiling that applied in 2024 and 2025.
Section 211.27a of the General Property Tax Act defines it broadly: a conveyance by deed, a land contract, certain leases longer than 35 years, many transfers through a trust, a foreclosure, or a tax-deed sale. Most ordinary home purchases trigger uncapping the calendar year after the sale.
Don't use the seller's current bill — it reflects their capped value, not yours. Estimate your taxable value at roughly half the purchase price (the SEV), then multiply by your city's total millage. Michigan's Treasury publishes a Property Tax Estimator, and I run this exact calculation for every client before they write an offer so there's no surprise at closing.
Yes. Transfers to a spouse, parent, child, sibling, grandchild, or adopted child are generally exempt from uncapping, as long as the property isn't used for a commercial purpose. The 2025 revision of Form 2766 puts extra emphasis on documenting that family relationship to claim the exemption.
Form 2766 (L-4260) is filed by the new owner with the local assessor within 45 days of the transfer. Missing the deadline can trigger back taxes, interest, and penalties calculated from the original due date, so it's not a form to let slide.
