Look up, pay and appeal your Northville taxes
Northville bills twice a year. The summer bill is issued July 1 and the winter bill December 1; most communities make them due September 14 and February 14, and anything still unpaid on March 1 moves to the county treasurer as delinquent, with interest added monthly. Both bills are collected by the Northville treasurer, so the balance on a specific parcel is on the city or township site first (most of Southeast Michigan uses BS&A Online for this) and on the county site once it is late.

- Oakland County Treasurer — where a bill goes once it is delinquent: balances, payment plans and the hardship deferral.
- Estimate a bill before you look one up — the figure on the current owner's statement is capped; this gives you the uncapped one.
Appealing the assessment
Assessment notices go out in late February. If the assessed value is more than half of what the house would actually sell for, the appeal runs in two steps and the first one cannot be skipped: the March Board of Review in Northville (dates and the petition form are on the assessor's notice), then, if the board does not move, a petition to the Michigan Tax Tribunal by July 31 for residential property. The July and December boards do not re-value: they correct qualified errors (clerical mistakes, mutual mistakes of fact, a wrong principal residence exemption) and hear poverty exemptions. A successful appeal lowers the assessed value, not the millage — the 39.9709 mills above apply to whatever value stands after it.
A home bought this year is a special case: the taxable value uncaps to the assessed value next year regardless of the appeal, so the number to check on the first notice after closing is the assessed value against the price you paid.
Common questions
What is the property tax rate in Northville, Michigan?
Northville is taxed at 39.9709 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 $6,995 a year.
Does the tax rate change by address within Northville?
No. All of Northville sits in Northville Public School District, so the millage is 39.9709 at every address in the municipality. Your bill still changes after you buy, because it is recalculated on the uncapped taxable value rather than the seller's capped one.
How much are property taxes on a $350,000 home in Northville?
About $6,995 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 Northville 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 Northville compare with the rest of Oakland County?
It is the 39 lowest of 52 municipalities in Oakland County and 163 of 236 across the eight-county region — 5.59 mills above the county median.
How do I look up or pay my Northville property tax bill?
Summer and winter bills are collected by the Northville treasurer, so the balance on a parcel is on the municipality's own site (usually BS&A Online). Once a bill is delinquent — March 1 — it moves to the Oakland County Treasurer, whose parcel search covers every address in the county.
How do I appeal my Northville property tax assessment?
Petition the Northville March Board of Review first — the dates are on the assessment notice mailed in late February — and, if that fails, the Michigan Tax Tribunal by July 31 for residential property. The board step is mandatory; the Tribunal will not hear a residential appeal that skipped it. An appeal changes the assessed value, not the millage (39.9709 mills).
