What happens to property taxes when you buy a home in Addison 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 Addison 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.

Proposal A

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 Addison 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 published rates

Addison Township's 2025 rates, district by district

School district	Homestead (PRE), mills	Non-homestead, mills
Almont Community Sc	27.4430	45.4430
Romeo Community Schools	31.5191	49.5191
Transfer Romeo/Oxford	32.9938	50.9938

The listing or the assessor's record says which school district a particular house sits in. Two homes a street apart in Addison Township can carry different rates for that reason alone.

The arithmetic

What the reset does to the bill.

A $300,000 purchase in Addison Township — Almont Community Sc 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, Almont Community Sc	27.4430 mills
Annual tax once the reset lands	$4,116

$300,000 × 50% = $150,000 taxable value. $150,000 × 27.4430 ÷ 1,000 = $4,116 a year. Rounded to the nearest dollar.

If you will not live in the home, the same purchase computes at the non-homestead rate of 45.4430 mills (Almont Community Sc): $6,816 a year, a difference of $2,700 against the homestead figure above.

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.

$400,000	$200,000	$5,489 to $7,197	$9,089 to $10,797

Ranges span the lowest and highest-rate school districts in the table above (Almont Community Sc to Transfer Oxford/Lk Orion). Rounded to the nearest dollar.

Deadlines

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 Addison 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

Questions

What buyers in Addison Township ask.

What is the 2025 property tax rate in Addison Township, Michigan?

It depends on the school district. The 2025 rates published by the Michigan Department of Treasury for Addison Township run from 27.4430 mills (Almont Community Sc) to 35.9830 mills (Transfer Oxford/Lk Orion) 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 Addison 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 Addison 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 $4,116 (Almont Community Sc) and $5,397 (Transfer Oxford/Lk Orion), depending on school district.

What is the Principal Residence Exemption worth in Addison Township?

In Addison Township the gap between the published non-homestead and homestead rates runs from 17.3155 to 18.0000 mills depending on school district. On a $300,000 purchase — $150,000 of taxable value after the reset — that computes to $2,597 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 Addison 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.
