Beyond the tax rate, three things shape what owning in Trenton actually costs: the age of the homes, what the water utility reports at the tap, and what local air testing has turned up. Each figure below carries the date of the survey it came from.

Common questions

What is the property tax rate in Trenton, Michigan?

Trenton is taxed at 56.5996–60.7625 mills for a homestead (principal residence) under the official 2025 Michigan Department of Treasury millage report. On a $350,000 home at the uncapped taxable value that is about $9,905 a year.

Does the tax rate change by address within Trenton?

Yes. Trenton spans 2 school districts and the rate runs from 56.5996 to 60.7625 mills depending on the district your address falls in — a difference of $729 a year on a $350,000 home. The district table above lists every rate.

How much are property taxes on a $350,000 home in Trenton?

About $9,905 a year at the homestead rate. Michigan taxes the taxable value, not the sale price, and after a sale that value uncaps to roughly half what you paid — so $350,000 is taxed on about $175,000.

Why is the tax bill on a Trenton listing lower than what I would pay?

Because the figure on the listing is the seller's. Michigan caps annual taxable-value growth while an owner keeps the property, and that cap is removed the year after it sells. The longer the seller owned it, the further their bill sits below yours.

How does Trenton compare with the rest of Wayne County?

It is the 36 lowest of 43 municipalities in Wayne County and 225 of 236 across the eight-county region — 6.52 mills above the county median.

Is down payment assistance available for homes in Trenton?

Likely, but verify per program: 100% of the 185 Trenton sales evaluated by Down Payment Resource over the last 12 months were flagged as potentially matching at least one assistance program. The flag is an indicator, not a promise — compare the programs and check your numbers.

Why this matters: the increase hits in the tax year after your closing — so your first year looks fine and year two jumps. Lenders often escrow off the seller's old bill, which creates a shortage and a payment increase you didn't plan for.
