Michigan Property Tax Estimator

Estimate your annual property taxes based on your Taxable Value and local millage. If you don’t know your Taxable Value, you can estimate it using SEV ≈ 50% of market value.

Current owner or future buyer?
• Current owner: enter your Taxable Value.
• Future buyer: use SEV (≈ 50% of market value).
Local mills
Enter the sum of local millages (city, county, library, school debt, etc.). The estimator will automatically add SET (6 mills) and, if it is not your principal residence, the 18 school operating mills.
Used only to estimate SEV (≈ 50%). Leave blank if you know your SEV or Taxable Value.
If left blank, it will be calculated as 50% of market value (if provided).
If provided, this becomes the final base for the calculation.
Include millages that apply area-wide. Exclude non-millage flat assessments/fees.
If yes, the 18 school operating mills are exempt. If no, they are added.
Recommended. The state’s official estimator displays rates that include it.

Default assumptions: State Education Tax (SET) = 6 mills. School Operating = 18 mills (only if NOT PRE). Formula: Annual tax = Taxable Value × (Total mills / 1000). If enabled, an additional +1% administration fee is applied.

This is an informational estimate and not tax advice. Special assessments and non-millage charges may not be included.

How to Use the Property Tax Estimator

This tool lets you quickly estimate how much you’ll pay in property taxes in Michigan. Fill out the fields step by step, and you’ll get an annual tax figure that’s close to your actual bill.

  1. Enter Market Value (optional): Type the estimated selling price of your home. The calculator will use 50% of that number to guess your SEV if you don’t know it.
  2. Provide SEV (optional): If you already have the State Equalized Value from your assessor, add it here. It’s usually about half of your market value.
  3. Add Taxable Value (if available): If you know your current Taxable Value, type it in. This is the number that property taxes are actually based on.
  4. Insert Local Mills (required): Write the total local millage rate for your area. You can find it on the Michigan Treasury site or your local tax bill.
  5. Select PRE status: Check the box if this is your principal residence. That will remove the 18 mills for school operating taxes.
  6. Apply the 1% fee: Decide if you want the 1% administration fee included. By default, it should be checked to mirror how actual bills are calculated.
  7. View your result: Press the button and the system will show you an annual tax estimate. You can then start over if you’d like to test another scenario.

How Property Taxes Work in Michigan

In Michigan, property taxes are calculated using your Taxable Value rather than the full market price of your home. Taxable Value is capped by law, so it can only increase each year by the rate of inflation or 5%, whichever is lower. That rule helps prevent sudden spikes in your tax bill when property prices rise quickly.

You’ll also see SEV, or State Equalized Value, on your property documents. This figure usually equals 50% of the market value. When a property changes hands, the Taxable Value is reset to match the SEV, which often means a noticeable jump in taxes for the new owner.

Rates are expressed in mills. One mill equals one dollar of tax for every $1,000 of Taxable Value. For example, if your Taxable Value is $100,000 and the total millage rate is 50, you’d owe $5,000 in annual property taxes. The total mills for your property include state, county, city, and school district rates.

Every homeowner in Michigan pays the State Education Tax of 6 mills. If the property is not your principal residence, another 18 mills for school operating are added. Local millages can vary widely depending on where you live, so two houses with the same value but in different counties may face very different bills.

What Is the Principal Residence Exemption (PRE)?

The Principal Residence Exemption is a rule in Michigan that lowers your property taxes if the home is your main residence. By claiming PRE, you avoid paying the 18 mills of school operating tax that apply to second homes, rentals, or investment properties.

To qualify, the house must be your primary living place, and you must have filed the exemption with your local assessor. If you move into a new home, you can usually transfer the exemption by submitting the proper form.

This exemption can make a significant difference in your annual bill. For example, a Taxable Value of $150,000 with 60 mills applied would generate about $9,000 in taxes. With PRE, the 18 mills are removed, cutting the bill by more than $2,500 each year.

Average Property Tax Rates by County

Property tax bills vary a lot depending on where you live in Michigan. Some counties keep millage rates moderate, while others are much higher because of local services, school funding, and debt obligations.

To give you a clearer picture, here’s a snapshot of several representative counties showing how median Taxable Value, effective rate, and average annual payment stack up.

CountyMedian Taxable ValueEffective RateAverage Annual Tax
Wayne$158,6001.73%$2,740
Oakland$302,8001.36%$4,124
Kent$242,2001.19%$2,889
Washtenaw$336,3001.56%$5,255
Ingham$173,6001.93%$3,346
These figures show how two homes with the same market value can generate very different bills depending on the county. That’s why it’s so important to check your local millage rates rather than relying on statewide averages.

FAQs About Michigan Property Taxes

What’s the difference between SEV and Taxable Value?

In Michigan, the State Equalized Value (SEV) usually equals 50% of your property’s market value. Taxable Value is the number your annual property tax bill is actually based on. When you buy a home, the Taxable Value resets to match the SEV, then grows only by the inflation rate or 5% per year.

How do I find the millage rate for my city or township?

You can look up local millage rates on the Michigan Department of Treasury website or request them from your local assessor’s office. The millage rate includes county taxes, city or township levies, school district operating mills, library mills, and special purpose assessments. Knowing the correct millage is key to getting an accurate estimate.

Why does my neighbor pay less in property taxes than I do?

Your neighbor may have a lower Taxable Value if they bought their home years ago. Michigan law limits yearly increases, so long-time owners often pay less than new buyers of similar houses. The Principal Residence Exemption (PRE) also affects the bill, since it removes the 18 school operating mills.

Does the Principal Residence Exemption really save money?

Yes. The PRE can reduce your effective tax rate significantly. Without it, you pay 18 extra mills. On a Taxable Value of $150,000, that’s an additional $2,700 every year. If the home is your main residence, you should always file the exemption with your local assessor.

Are property tax bills the same as special assessments?

Not exactly. Your property tax bill is based on the Taxable Value and the total millage rate. Special assessments are separate charges for things like sewer upgrades, road paving, or garbage collection. These don’t follow the millage system and can add hundreds of dollars to your yearly payment.

Can property taxes increase even if home prices don’t?

Yes. Even if market values are flat, millage rates can rise if voters approve new levies for schools, fire protection, or public safety. That’s why two homes with the same Taxable Value might see different annual property tax payments if one area recently passed a new millage.

Where should I verify my official tax bill?

Always confirm your numbers with your local city or township assessor and the Michigan Treasury. The calculator on this page is for educational use, but your actual tax liability depends on official records, current millage rates, and any special assessments specific to your property.
