Look up, pay and appeal your Green Oak Township taxes

Green Oak Township 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 Green Oak Township 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.

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 Green Oak Township (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 25.3046–34.9856 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 Green Oak Township, Michigan?

Green Oak Township is taxed at 25.3046–34.9856 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 $4,428 a year.

Does the tax rate change by address within Green Oak Township?

Yes. Green Oak Township spans 3 school districts and the rate runs from 25.3046 to 34.9856 mills depending on the district your address falls in — a difference of $1,694 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 Green Oak Township?

About $4,428 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 Green Oak Township 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 Green Oak Township compare with the rest of Livingston County?

It is the 15 lowest of 19 municipalities in Livingston County and 58 of 236 across the eight-county region — 2.45 mills above the county median.

How do I look up or pay my Green Oak Township property tax bill?

Summer and winter bills are collected by the Green Oak Township 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 Livingston County Treasurer, whose parcel search covers every address in the county.

How do I appeal my Green Oak Township property tax assessment?

Petition the Green Oak Township 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 (25.3046–34.9856 mills).

Is down payment assistance available for homes in Green Oak Township?

Likely, but verify per program: 90% of the 208 Green Oak Township 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.
