Quick answer: Michigan property tax is calculated on your home's
taxable value, not its market price. Taxable value is roughly half
of market value (the State Equalized Value), capped yearly under Proposal
A. The formula is Annual tax = Taxable Value × (Millage ÷ 1,000).
A primary residence claiming the Principal Residence Exemption (PRE) drops
18 school operating mills, which can cut the bill nearly in half versus a
rental or second home.

Enter market value (or your known taxable value) and your local millage rate.
Enter your home's market value. The calculator sets the assessed
value (SEV) at 50% of this figure automatically.
Add your known taxable value if you have it. Your assessment
notice or county lookup lists it. For long-term owners it is often lower
than 50% of market value because of the Proposal A cap.
Enter your total millage rate. Find it on your latest tax bill
or your city, township, or county website.
Choose homestead or non-homestead. Homestead applies the PRE and
removes 18 school operating mills.

How Michigan property tax is calculated
Michigan does not tax your home at its full market price. Under the General
Property Tax Act, the assessed value is set at 50% of true cash value, and
under Proposal A (1994) the taxable value your bill is built on is capped so
it cannot rise faster than 5% or inflation per year, whichever is less. The
bill itself is simple once you have the taxable value:
Assessed value (SEV) = Market value × 50%
Annual tax = Taxable value × ( Millage ÷ 1,000 )
Homestead: use ( Millage − 18 school mills )
A mill is $1 of tax per $1,000 of taxable value. According to the
Michigan
Department of Treasury, an owner-occupant who files a Principal Residence
Exemption is shielded from the 18 mills of local school operating tax, which
is the single biggest reason two identical homes can have very different
bills.
The same home as a non-homestead rental would use the full 50 mills:
$175,000 × 0.050 = $8,750 a year. That $3,150 gap is the value of the PRE.

Key Michigan property tax terms
True cash value — the assessor's estimate of your home's market
value.
State Equalized Value (SEV) — exactly 50% of true cash value.
Taxable value — the capped figure your bill is actually built
on; under Proposal A it rises no faster than 5% or inflation per year
while you own the home.
Uncapping — when a home sells, its taxable value resets to the
SEV the year after closing, which often raises the new owner's bill.
Principal Residence Exemption (PRE) — removes 18 school
operating mills for an owner-occupied primary home; file by the state
deadline with your local assessor.

Michigan property tax FAQs
How is property tax calculated in Michigan?
Michigan multiplies your taxable value by your local
millage rate divided by 1,000. Taxable value is capped under Proposal A
and is usually about half of market value. A home with $175,000 taxable
value at 50 mills owes $8,750 a year.
What is the homestead PRE exemption worth?
The Principal Residence Exemption removes 18 school
operating mills from an owner-occupied primary home. On a home with
$175,000 taxable value that is about $3,150 saved each year, often
cutting the bill nearly in half versus a rental.
What is the difference between SEV and taxable value?
State Equalized Value is exactly 50% of market value.
Taxable value is the Proposal A capped figure your bill is built on, which
can be lower than SEV for long-term owners because it rises no faster than
5% or inflation per year.
Why did my Michigan property tax go up after I bought?
When a home sells, its taxable value uncaps and resets to
the State Equalized Value the following year. If the prior owner held it a
long time, their capped taxable value was low, so your uncapped bill can
be noticeably higher.
What is a mill in Michigan property tax?
A mill is $1 of tax for every $1,000 of taxable value.
So 50 mills on $175,000 of taxable value is $175,000 divided by 1,000,
times 50, which equals $8,750 per year before any exemptions.
Do rental properties pay more property tax in Michigan?
Yes. Rentals, second homes, and investment properties are
non-homestead, so they cannot claim the PRE and pay the full millage
including the 18 school operating mills. On identical homes, a rental owes
materially more than an owner-occupant.
Is this Michigan property tax calculator accurate?
It gives a close estimate using the state's 50%
assessment ratio, Proposal A method, and PRE. Actual bills vary by
municipality, school district, and special assessments. Confirm figures
with your local assessor or the Michigan Department of Treasury.
