Quick answer: Michigan tax is charged on taxable value, not market price: annual tax = taxable value × (millage ÷ 1,000). Taxable value is roughly half of market value and capped each year. A primary residence with the Principal Residence Exemption drops 18 school mills, about 36% off the bill at 50 mills.
How Michigan property tax is calculated
annual tax = taxable value × (millage ÷ 1,000)SEV = market value × 50% · homestead uses millage − 18Under the General Property Tax Act, assessed value (SEV) is 50% of true cash value. Under Proposal A (1994), taxable value cannot rise faster than 5% or inflation a year, whichever is less, while you own the home.
A mill is $1 of tax per $1,000 of taxable value. According to the Michigan Department of Treasury, owners who file a Principal Residence Exemption are exempt from the 18 mills of local school operating tax.
Worked example: a $350,000 home
$350,000 primary residence at 50 mills
- SEV: $350,000 × 50% = $175,000
- Homestead millage: 50 − 18 = 32
- Tax: $175,000 × 32 ÷ 1,000 = $5,600
Result: $5,600 a year (about $467 a month)
As a non-homestead rental the same home pays the full 50 mills: $8,750. The $3,150 gap is the value of the exemption. Because it is a flat 18 mills, it removes about 72% of the bill in a 25-mill township and about 30% in a 60-mill city.

Millage is voter-approved and varies by city, township and school district. Neighbouring areas can differ by 10 mills or more, so use the exact rate from your own bill.

Frequently asked questions
How is property tax calculated in Michigan?
Taxable value × (millage ÷ 1,000). Taxable value is capped under Proposal A and is usually about half of market value. $175,000 taxable value at 50 mills is $8,750 a year before the homestead exemption.
What is the homestead PRE exemption worth?
The Principal Residence Exemption removes 18 school operating mills from an owner-occupied home. On $175,000 taxable value that saves $3,150 a year, about 36% of the bill at 50 mills.
What is the difference between SEV and taxable value?
State Equalized Value is 50% of market value. Taxable value is the capped figure the bill uses, and for long-term owners it can be well below SEV because it rises no faster than 5% or inflation a year.
Why did my Michigan property tax go up after I bought?
When a home sells, its taxable value uncaps to the SEV the following year. If the previous owner held it for years, their capped value was low, so your bill can jump.
What is a mill?
$1 of tax for every $1,000 of taxable value. 50 mills on $175,000 is $175,000 ÷ 1,000 × 50 = $8,750.
Do rental properties pay more property tax in Michigan?
Yes. Rentals and second homes cannot claim the PRE, so they pay the full millage including the 18 school operating mills.
