What happens to property taxes when you buy a home in Green Oak Township, MI
The tax figure on the listing is the seller's bill, computed under a cap that ends the day you close. The January after the sale, the Green Oak Township assessor resets the taxable value to about half of what you paid, and your bill is built from that new number at the rates below.
The seller's bill is not your bill.
Michigan's Proposal A freezes how fast a home's taxable value can grow while one owner holds it, often far below what the home is now worth. A sale uncaps it. The assessor resets the taxable value to the state equalized value, which is about half the market value, and every bill after that is computed from the reset figure. Buyers who budget from the listing's tax line usually meet the real number in year two.
Two things set the size of the reset bill in Green Oak Township: the price you pay, and whether you live in the home. Living there qualifies you for the Principal Residence Exemption, and the exact rate depends on the school district the house sits in.

The listing or the assessor's record says which school district a particular house sits in. Two homes a street apart in Green Oak Township can carry different rates for that reason alone.
What the reset does to the bill.
A $300,000 purchase in Green Oak Township — Brighton Area School district, worked line by line.
| Line | Figure |
|---|---|
| Purchase price | $300,000 |
| Taxable value after the uncap (state equalized value, about half the price) | $150,000 |
| Homestead rate, Brighton Area School | 25.3046 mills |
| Annual tax once the reset lands | $3,796 |
$300,000 × 50% = $150,000 taxable value. $150,000 × 25.3046 ÷ 1,000 = $3,796 a year. Rounded to the nearest dollar.
The reset uses exactly half the price here, where the assessor's figure will be approximately half. Your actual bill depends on the assessor's next determination of state equalized value and on any millage voters approve between now and then.
The same arithmetic at three round numbers.

The paperwork that sets your rate.
Two filings decide which column above your bill is computed from, and one of them carries a penalty.
Principal Residence Exemption — Form 2368
If you will live in the home, this filing is what puts you on the homestead column instead of the non-homestead one. File it with the Green Oak Township assessor.
| Summer levy | June 1 |
| Winter levy | November 1 |
Property Transfer Affidavit — Form 2766
Due to the assessor after the transfer. It is the filing that tells the assessor the sale happened, and missing it is the one deadline here that costs money.
| Due | 45 days from transfer |
| Penalty, residence | $5 per day, $200 max |
What buyers in Green Oak Township ask.
What is the 2025 property tax rate in Green Oak Township, Michigan?
It depends on the school district. The 2025 rates published by the Michigan Department of Treasury for Green Oak Township run from 25.3046 mills (Brighton Area School) to 34.9856 mills (Whitmore Lake Pub Sc) with a Principal Residence Exemption. The listing or the assessor's record says which district a house is in; the full table is on this page.
Why will my property taxes in Green Oak Township be higher than the seller's?
Michigan's Proposal A caps how fast a home's taxable value can rise while one person owns it. A sale removes the cap: the January after you close, the taxable value resets to the state equalized value — about half the market value — and your bill is computed from that reset number, not from the seller's capped one. The figure on the listing is the seller's bill under the old cap.
How much would property taxes be on a $300,000 home in Green Oak Township?
As an arithmetic illustration, not a statistic about local prices: taxable value resets to about half the price — the illustration uses exactly $150,000 — and at the published homestead rates the annual bill computes to between $3,796 (Brighton Area School) and $5,248 (Whitmore Lake Pub Sc), depending on school district.
What is the Principal Residence Exemption worth in Green Oak Township?
In Green Oak Township, the gap between the published non-homestead and homestead rates is 18.0000 mills. On a $300,000 purchase — $150,000 of taxable value after the reset — that computes to $2,700 a year. You claim it by filing Form 2368 with the assessor: June 1 for the summer levy, November 1 for the winter levy.
What do I have to file after buying a home in Green Oak Township?
Two forms. The Property Transfer Affidavit (Form 2766) goes to the assessor within 45 days of the transfer; the penalty for missing it runs $5 a day up to $200 for a residence. The Principal Residence Exemption (Form 2368) is due June 1 for the summer levy and November 1 for the winter levy if you will live in the home.
Everything on this page is arithmetic on rates published by the Michigan Department of Treasury, for screening. Your actual bill depends on the assessor's next determination and any millage voters approve. Nothing here is legal, tax, or lending advice, and nothing here is an opinion of value.
