Michigan property tax: the complete homeowner's guide

The big picture

Michigan's effective property tax rate is roughly 1.25% of market value — above the national average — even though the state has one of the country's stricter limits on how fast a tax bill can grow. That apparent contradiction is the heart of Michigan property tax, and it comes from a single design choice made by voters in 1994: Proposal A. Since then, Michigan has run a two-value system. One value, the State Equalized Value, tracks the market. The other, the Taxable Value, is capped and grows slowly. Your bill rides on the capped value, but the millage rates that get applied to it are high — and the result lands the effective burden above average despite the cap.

Three ideas carry most of the weight in this guide, and they're worth naming up front:

• Homes are assessed at 50% of market value, and the bill is levied on a separate, capped Taxable Value.
• When a home sells, it "uncaps" — the single biggest surprise for Michigan buyers.
• The Principal Residence Exemption removes most, but not all, local school tax from an owner-occupied home.

SEV vs. Taxable Value

Every year, your city or township assessor estimates your home's True Cash Value — Michigan's term for market value — and sets the Assessed Value at 50% of that figure. After the county equalizes assessments across jurisdictions, that number becomes the State Equalized Value (SEV). So a home with a True Cash Value of $300,000 carries an SEV of roughly $150,000. The SEV moves with the market every year, up or down, with no cap.

Your bill, however, is not calculated on the SEV. Since Proposal A took effect, tax is levied on Taxable Value, which can rise each year by only the lesser of 5% or the rate of inflation (the Consumer Price Index). In most years inflation is well under 5%, so the practical cap is the inflation figure — often in the low single digits. The year you buy and occupy a home, its Taxable Value and SEV are usually the same. But as the market appreciates faster than inflation, the SEV climbs while the Taxable Value crawls. Year after year the two diverge, and the gap is real money: tax is charged only on the lower, capped number.

This is why two neighbors in identical houses can pay strikingly different bills. The owner who has held the home for fifteen years sits on a Taxable Value far below market, while a recent buyer pays on a value near the SEV. Nothing about the houses differs — only the length of ownership and the moment the cap last reset.

Uncapping when you buy

Here is the mechanism that catches more Michigan buyers off guard than any other. When a property changes ownership, it "uncaps": the following year, the Taxable Value resets all the way up to the SEV, and the Proposal A cap starts over from there. If the seller had owned the home a long time, their Taxable Value may have drifted far below market — which means the reset is a big jump.

Concretely: a seller who bought years ago might be taxed on a Taxable Value of $90,000 while the home's SEV has climbed to $150,000. The year after you buy, your Taxable Value pops up to that $150,000 SEV. Your bill can be substantially higher than the seller's was on the very same house, even though nothing physical changed. This "pop-up" is not a penalty and not a reassessment error — it is Proposal A working exactly as designed, and it's why the previous owner's tax bill is a poor estimate of what you'll pay.

The takeaway for buyers: never budget from the seller's current bill. Estimate your bill from the SEV (roughly half of market value) and the local millage rate, because that's close to where your Taxable Value will land after the uncap. Michigan Treasury's Property Tax Estimator lets you do exactly that. Our reassessment impact tool can also help you see how a jump in taxable value flows through to the bill.

The Principal Residence Exemption

Michigan's central homeowner break is the Principal Residence Exemption (PRE). A home you own and occupy as your principal residence is exempt from up to 18 mills of local school operating tax. On a home with meaningful taxable value, that exemption is worth real money every year, and it's the difference between a homestead bill and a non-homestead bill on otherwise identical property.

One caveat matters enough to state plainly, because it's widely misunderstood: the PRE does not exempt your home from all school taxes. The 6-mill State Education Tax still applies to a PRE-qualified home. The exemption removes the local school operating millage (up to 18 mills); it does not touch the statewide 6-mill levy. So a principal residence pays less school tax than a rental or second home next door — but not zero.

Because the PRE is tied to occupancy, it doesn't transfer with the property. When you buy, you generally need to file the exemption form for your own home; the previous owner's PRE doesn't carry over to you automatically the way you might expect.

Other relief

Two additional programs are worth knowing:

• Homestead Property Tax Credit. An income-based credit claimed on the Michigan income-tax return (form MI-1040CR). For tax year 2024, the maximum credit is $1,800. Eligibility phases out as income rises: there is no credit once total household resources exceed $69,700, the home's taxable value must be at or below $160,700, and the credit phases down by 10% for each $1,000 of household resources above $60,700. It's aimed squarely at lower- and middle-income owners and renters whose property tax is large relative to their income.
• Disabled Veterans Exemption. A qualifying 100%-disabled veteran's homestead can be fully exempt. A meaningful administrative change arrived with PA 150–152 of 2023: beginning January 1, 2025, an approved exemption continues without requiring an annual reapplication, and the assessor — rather than the Board of Review — grants or denies it. For veterans who previously had to refile every year, that's a real reduction in paperwork.

Why Michigan rates run high

If Proposal A caps growth so tightly, why does Michigan's effective rate still sit near 1.25% — above the national average? Two structural reasons.

First, the Headlee Amendment rolls a unit's authorized millage back only when its total taxable base grows faster than inflation — a constraint on revenue growth, not a force that pushes rates down to a low baseline. Authorized millage rates stay comparatively high.

Second, and more visibly, a Michigan home usually sits inside several overlapping taxing units at once — county, city or township, school district, intermediate school district, community college, library, and often more. Each levies its own authorized millage, and those millages stack on the same taxable value. Add them up and the combined local rate climbs above the national average. The cap restrains how fast your taxable base grows; it does nothing to thin out the number of millages applied to it.

Appeals

If you believe your assessment overstates your home's True Cash Value, Michigan gives you a path to challenge it. The first stop is your local March Board of Review, which hears assessment challenges early in the year after assessment notices go out. You present evidence — comparable sales, an appraisal, documentation of condition — that your Assessed Value (50% of True Cash Value) is too high.

If the Board of Review doesn't resolve it, residential homestead appeals generally escalate to the Michigan Tax Tribunal, the state-level body that hears property tax disputes. Deadlines are firm and depend on the property type and the step in the process, so the practical advice is to read your assessment notice carefully when it arrives and act early rather than assume you can appeal at any time. Because the appeal targets the underlying True Cash Value, a successful reduction lowers both your SEV and, in turn, the taxable value your bill rides on.

Common mistakes

• Forgetting to file the Principal Residence Exemption. The PRE doesn't follow the house to a new owner automatically. If you buy and don't file for your own principal residence, you can end up paying the non-homestead rate — up to 18 extra mills of local school operating tax — on a home that qualifies for the exemption.
• Not expecting the uncap pop-up. Budgeting from the seller's current tax bill is the classic Michigan buyer mistake. The year after you buy, the home uncaps and your Taxable Value resets to the SEV — so estimate from roughly half the market value times the local millage, not from what the seller paid.
• Assuming the PRE zeroes out school tax. It doesn't. The 6-mill State Education Tax still applies even to a PRE home, so a principal residence pays less school tax than a non-homestead property, not none.

Putting it together

Michigan's property tax is built around one elegant, occasionally bewildering idea: tax the slow-growing Taxable Value, not the market-tracking SEV — until a sale resets the clock. Get comfortable with that, and the rest falls into place. Assess at 50% of market value, cap the bill's growth, expect the pop-up when ownership changes, file the PRE to shed up to 18 school mills (while still paying the 6-mill State Education Tax), and recognize that the effective rate runs high because many local millages stack on the same base.
