Michigan Property Tax Estimator - Brighton, South Lyon, Howell, and Southeast Michigan
Michigan Property Tax Estimator - Brighton, South Lyon, Howell, and Southeast Michigan
Understand uncapping, the Principal Residence Exemption, proration at closing, and how Michigan property taxes affect your purchase cost or your net proceeds
If you are buying a home in Brighton, South Lyon, Howell, Lyon Township, Milford, New Hudson, Hartland, Pinckney, or anywhere across Livingston, Washtenaw, Oakland, and Wayne County, the property tax bill on your new home will almost certainly be higher than the seller's bill on the same home. Michigan's tax system caps year-over-year increases for current owners and uncaps the taxable value when a property transfers, which is why running an estimate based on your purchase price, before you write an offer, is one of the most useful things a buyer can do. Use the Michigan Department of Treasury's official estimator below, then read the sections that follow.

Enter the property details below to estimate annual property taxes. This is the official State of Michigan estimator and it works for any Michigan address. To model your actual expected tax bill as a buyer, use the property's purchase price as the basis for taxable value rather than the seller's current capped amount.
How Michigan Property Taxes Are Calculated
Michigan property assessment and taxation follows a structure established by Proposal A of 1994. Four terms drive your bill:
- Assessed Value (AV): Set by your local assessor at 50% of the property's estimated market value. Reassessed annually.
- State Equalized Value (SEV): The assessed value after county and state equalization review. Usually the same as AV for residential property.
- Taxable Value (TV): The value actually used to calculate your tax bill. While you own the home, TV increases annually by the rate of inflation or 5%, whichever is lower, regardless of how much market value has grown. This is the cap. For 2026, the Michigan State Tax Commission set the inflation rate multiplier at 1.027, or 2.7%.
- Millage Rate: The tax rate per $1,000 of taxable value. Varies by township, city, county, and local school operating millage.
Your annual tax bill equals your taxable value divided by 1,000, multiplied by your applicable millage rate. A home with a $150,000 taxable value in a jurisdiction with a 35-mill rate generates a tax bill of about $5,250 annually.
Uncapping - Why a Buyer's Tax Bill Is Usually Higher Than the Seller's
When a Michigan property sells, the taxable value uncaps. It resets from the previous owner's capped taxable value to the current state equalized value, which reflects current market conditions. Michigan REALTORS® refer to this as the Pop-Up Tax. For a home held for many years in an area where market value grew faster than the inflation cap allowed taxable value to grow, the increase can be substantial rather than incremental. The Treasury estimator above calculates taxes at the new uncapped value, not what the current owner is paying.
Michigan property tax uncapping explained covers the mechanics in full: a worked example using actual Livingston County millage rates, every inflation rate multiplier published since Proposal A took effect in 1995, how to compare a property's state equalized value against your purchase price before you write an offer, and the 45-day Property Transfer Affidavit filing requirement that falls on the buyer.
The Principal Residence Exemption - The 18-Mill Difference
Michigan exempts an owner-occupied principal residence from up to 18 mills of local school operating tax. A property that does not qualify, including a second home, vacation property, rental, or investment property, pays that millage in full. The Treasury estimator above includes a Principal Residence Exemption checkbox, so you can model both scenarios on the same address before you write an offer.
Two things about the exemption catch buyers out. It is not automatic and it does not transfer to you at closing, so a home that was exempt for the seller will be billed without the exemption for you unless you file. And exemption status can change during a year without appearing on a bill that has already been issued, which means a home showing as exempt on the current bill can be billed at the higher rate the following year.
The Michigan Principal Residence Exemption explained covers the full mechanics: what the exemption is worth in dollars at actual Livingston County millage rates, the June 1 and November 1 filing deadlines that decide which bill you pay, the rescind-then-file sequence and the forms involved, the conditional rescission available to an owner who has moved but not yet sold, and why exemption status needs to be verified with the assessing jurisdiction rather than taken from a listing.
Michigan Property Tax Proration at Closing
Michigan collects property taxes in two billings per year: summer, billed July 1, and winter, billed December 1. Actual due dates vary by municipality, but due dates in this area are generally September 14 for summer taxes and February 14 for winter taxes. At closing, the title company prorates property taxes between buyer and seller based on the portion of the tax period each party owned the home.
The method used to prorate follows local custom, and that custom is where buyers and sellers coming from out of state most often get caught:
- Southeast Michigan prorates as paid in advance. Across Livingston, Oakland, Washtenaw, and Wayne Counties, each tax billing is treated as covering a period that runs forward from the levy date. Because the seller has already paid through a date beyond closing, the buyer reimburses the seller for the unused portion of that period.
- Some other Michigan jurisdictions prorate as paid in arrears. There, the billing is treated as covering a period that has already elapsed, and the seller credits the buyer for the days the seller owned the home. That is the opposite direction of money at the closing table.
- The two methods produce materially different numbers. On a mid-cycle closing, the difference between advance and arrears treatment on the same property can run into the thousands of dollars.
- Mid-year PRE transitions add a second variable. If a seller loses the Principal Residence Exemption during the year, or a buyer establishes it after closing, the underlying tax amount being prorated can change.
Local custom is the default assumption, not a rule that overrides the contract. The purchase agreement governs, which is why its proration language needs to state what the parties actually intend. Derek reviews proration language on every transaction so buyers and sellers are not caught by a convention they did not know applied.
County and Township Variation Across the Brighton, South Lyon, and Howell Area
Millage rates vary by jurisdiction. Here is the geographic breakdown for the primary service areas:
- Brighton area: Livingston County. City of Brighton, Genoa Township, Brighton Township, Green Oak Township, Hamburg Township.
- Howell area: Livingston County. City of Howell, Howell Township, Marion Township, Oceola Township.
- South Lyon area: Splits between Oakland County covering most of South Lyon and Lyon Township, Livingston County covering Green Oak Township portions, and Washtenaw County covering some western areas. Verify the specific property's jurisdiction before estimating.
- Milford and New Hudson: Oakland County. Milford Township, Lyon Township, Commerce Township.
- Hartland, Pinckney, Fowlerville: Livingston County.
- Whitmore Lake: Splits between Washtenaw County and Livingston County depending on the specific address.
Local school operating millage also affects the total bill. Even within a single township, total millage can differ depending on which local school operating area the property falls in. Green Oak Township is a clear example: 2025 principal residence rates there range from 25.3046 mills to 34.9856 mills, a spread of nearly 10 mills inside one township. The Treasury estimator handles this automatically when you enter the address.
Buying? Get Clear on Carrying Costs Before You Write an Offer
Your Michigan property tax bill is one of the largest recurring carrying costs of home ownership, often larger than homeowners insurance and HOA dues combined. Understanding uncapping, the PRE differential, and any special assessments before you write an offer means no surprises when the first tax bill arrives after closing.
If you want help thinking through the full carrying cost picture on a specific property, including financing, taxes, insurance, HOA where applicable, and what your monthly payment will actually look like at the closing table, start a Buyer Discovery Session or explore the 12-tool buyer and seller toolkit at MovingRealityCheck.com.

Frequently Asked Questions
How are property taxes calculated in Michigan?
Michigan property is assessed at 50% of its estimated market value. The taxable value is capped at the rate of inflation or 5% annually, whichever is lower, until the property transfers. For 2026 the inflation rate multiplier is 1.027. Your annual tax bill equals your taxable value divided by 1,000, multiplied by your applicable millage rate. Millage rates vary by township, city, county, and local school operating millage across Brighton, South Lyon, Howell, Lyon Township, and surrounding Livingston, Oakland, and Washtenaw County communities.
What is property tax uncapping in Michigan and why does it matter to buyers?
When a Michigan property sells, the taxable value uncaps and resets from the previous owner's capped value to the current state equalized value. This is referred to as the Pop-Up Tax. For a home owned for many years where market value has grown faster than the inflation cap on taxable value, the uncapping impact can add hundreds of dollars per month to a buyer's tax bill. Always run the Treasury estimator with the specific property address and planned purchase price before writing an offer. For the full mechanics, including a worked example and the 45-day filing requirement, see Michigan property tax uncapping explained.
What is the Principal Residence Exemption and how does it affect my Michigan property tax bill?
The Principal Residence Exemption exempts a Michigan owner-occupant's principal residence from up to 18 mills of local school operating tax. Properties that do not qualify, including second homes, vacation homes, rentals, and investment properties, pay the full operating millage including those 18 mills. The differential is statewide and applies anywhere in Michigan. The exemption is not automatic and does not transfer to a buyer at closing, and exemption status can change mid-year without appearing on a bill that has already been issued. The Treasury estimator includes a Principal Residence Exemption checkbox so you can model both scenarios. For the filing deadlines, the forms involved, and what to verify before writing an offer, see the Michigan Principal Residence Exemption explained.
How are property taxes prorated at closing in Michigan?
Michigan collects property taxes in two billings: summer, billed July 1 and generally due September 14, and winter, billed December 1 and generally due February 14. Due dates vary by municipality. At closing, the title company prorates property taxes between buyer and seller based on the portion of the tax period each party owned the home. Across Southeast Michigan, including Livingston, Oakland, Washtenaw, and Wayne Counties, taxes are prorated as paid in advance, meaning the buyer reimburses the seller for the portion of the billing period falling after closing. Some other Michigan jurisdictions prorate as paid in arrears, which reverses the direction of the credit. The purchase agreement governs, so its proration language matters.
Do property tax rates differ between Brighton, South Lyon, and Howell?
Yes, substantially. Millage rates vary by township, city, and local school operating millage. Brighton area properties are in Livingston County. South Lyon area properties may fall in Oakland County, Livingston County, or Washtenaw County depending on the specific jurisdiction. Howell area properties are in Livingston County. Rates can also differ within a single township depending on the local school operating area. The Treasury estimator handles these differences automatically when you enter the property address.
What is the difference between assessed value, state equalized value, and taxable value?
Assessed value is set by your local assessor at 50% of the estimated market value. State equalized value is the assessed value after county and state equalization review. Taxable value is what your tax bill is actually calculated on. It is capped at the rate of inflation or 5% annually while you own the property, and uncaps to state equalized value when the property sells. For most long-term owners, taxable value is lower than state equalized value, which is why uncapping increases the new buyer's bill.
How do property taxes affect my net proceeds when I sell in Michigan?
Property tax proration is one of several variables that affects your final net proceeds, alongside mortgage payoff, Michigan state and county transfer taxes, title insurance, closing costs, and negotiated broker compensation. The free Michigan Net Proceeds Calculator at SellerProceeds.com includes property tax proration so you can model what you actually walk away with.
