Wayne County property tax is calculated by multiplying your property’s Taxable Value by the total millage rate for your address, with bills issued in two installments each year and a wide range of exemptions, credits, and payment plans that can lower what you owe or keep you out of foreclosure if you fall behind. Because millage rates differ sharply across the county’s 43 communities, two homes with the same market value can produce very different bills, so the specifics of your address matter as much as the value of your house.
How Your Bill Is Calculated
Michigan’s General Property Tax Act requires every property to be assessed at its State Equalized Value, which equals 50 percent of estimated market value.1Michigan Legislature. Michigan Compiled Laws 211.1 – Property Subject to Taxation A home that would sell for $200,000 should have a State Equalized Value of about $100,000.
Your Taxable Value is usually lower. Under Proposal A, passed in 1994, Taxable Value can rise each year by only the lesser of the inflation rate or 5 percent, regardless of how fast the market moves. For the 2026 tax year, the State Tax Commission set the inflation rate multiplier at 1.027, capping the annual increase at 2.7 percent for existing owners.2Fort Gratiot Township. State Tax Commission Bulletin 15 of 2025 – Procedural Changes for 2026 Over the years, this cap opens a growing gap between Taxable Value and State Equalized Value in neighborhoods where prices have climbed.
The tax itself is Taxable Value multiplied by the total millage rate, where one mill equals one dollar per thousand dollars of Taxable Value. A Taxable Value of $100,000 in a community with a 50-mill rate produces a $5,000 annual bill. Rates in Wayne County range from roughly 28 mills for homestead properties in some southern townships to more than 70 mills in communities such as Harper Woods and River Rouge.3Michigan Department of Treasury. Total Property Tax Rates in Michigan 2025 The rate at your address combines county, city or township, school district, community college, library, and any special authority levies.
What Happens When You Buy
Sales trigger an “uncapping.” When a home changes ownership, the Taxable Value resets to equal the State Equalized Value. A property held for many years under the annual cap may have a Taxable Value well below current market conditions, and the new owner’s first bill reflects the full jump. This is the single biggest surprise for new Wayne County homeowners and can add hundreds or thousands of dollars over what the seller was paying.
Every buyer must file a Property Transfer Affidavit (Form 2766) with the local assessor within 45 days of the transfer.4Michigan Department of Treasury. Property Transfer Affidavit – Form 2766 For residential properties, missing the deadline triggers a penalty of $5 per day up to $200. Some transfers between family members or into certain trusts are exempt from uncapping, but the affidavit still has to be filed with the exemption indicated on the form.
When Taxes Are Due
Wayne County property tax is billed in two cycles. Summer bills become a lien on July 1 and are due by September 14. Winter bills become a lien on December 1 and are due by February 14.5Michigan Department of Treasury. Frequently Asked Questions – State Education Tax If a due date falls on a weekend or holiday, it extends to the next business day. Some cities set different dates by charter, so check your bill.
Late summer payments accrue interest at 1 percent per month starting the day after the deadline. Late winter payments face a 3 percent penalty added on the first business day after February 14. Anything still unpaid at the end of February is turned over to the Wayne County Treasurer as delinquent, and the costs escalate sharply from there.

Exemptions and Credits
Principal Residence Exemption
If you own and occupy your home as your primary residence, the Principal Residence Exemption removes up to 18 mills of the local school operating tax from your bill.8Michigan Department of Treasury. Principal Residence Exemption In a county where total rates often exceed 50 mills, that can cut a bill by roughly a quarter to a third. File the affidavit with your local assessor. The exemption stays in place until you move or sell; if you buy a new primary residence, file a new affidavit at the new address and rescind the old one.
Disabled Veteran Exemption
Veterans rated 100 percent permanently and totally disabled by the U.S. Department of Veterans Affairs are exempt from all property taxes on their homestead. The exemption also covers veterans receiving VA assistance for specially adapted housing and those rated individually unemployable.9Michigan Legislature. Michigan Compiled Laws 211.7b – Exemption of Real Property Used and Owned as Homestead by Disabled Veteran or Surviving Spouse A surviving spouse who has not remarried can continue to receive it. Unlike most exemptions, this one eliminates the bill rather than reducing it. Apply through your local assessor.
Poverty Exemption
Residents who cannot afford their property taxes because of poverty may qualify for a partial or complete exemption. Each local unit sets its own income and asset thresholds, which have to meet or exceed the federal poverty guidelines.10Michigan Legislature. Michigan Compiled Laws 211.7u – Principal Residence of Persons in Poverty; Exemption From Taxation Apply through your local Board of Review. The exemption has to be renewed annually, and because guidelines differ by municipality, contact your local assessor for the limits that apply to you.
Homestead Property Tax Credit
Even without the exemptions above, you may recover part of what you pay through Michigan’s homestead property tax credit, claimed on your state income tax return rather than through the local assessor. For non-seniors, the credit equals 60 percent of the amount your property taxes exceed 3.2 percent of your total household resources.11Michigan Legislature. Michigan Compiled Laws 206.522 – Homestead Property Tax Credit; Amount of Claim Seniors qualify for a higher credit percentage that scales with income, up to a maximum of $1,200. It is one of the most underused benefits in Wayne County because many homeowners don’t realize property tax relief can come through their state return.
Challenging Your Assessment
If you think your assessed value is too high, the first formal step is your local March Board of Review. Every city and township convenes one in early March to hear protests. In Detroit, petitions for the 2026 March Board of Review must be filed by 4:30 p.m. on March 9, 2026, with the board sitting through early April.12City of Detroit. Property Assessment Board of Review Other communities set their own dates, so check with your local clerk.
Appeals use Form 618 (L-4035), the Board of Review Petition Form. Bring evidence tied to value: recent sales of comparable homes, photographs of structural defects or needed repairs, contractor estimates, and any appraisal you’ve obtained. The board weighs your evidence against the assessor’s data, so unsupported complaints about the bill being “too high” rarely succeed.
If the Board of Review denies your appeal, you can escalate to the Michigan Tax Tribunal. For residential property the filing deadline is July 31 of the tax year involved; commercial and industrial owners face a May 31 deadline. You have to have appeared before the Board of Review first, or the Tribunal will not hear the case.
If You Fall Behind
Taxes still unpaid at the end of February are returned as delinquent to the Wayne County Treasurer on March 1. At that point the county adds a 4 percent administration fee and begins charging interest at 1 percent per month, calculated from the original delinquency date.13Michigan Legislature. Michigan Compiled Laws 211.78a – Property Returned as Delinquent Subject to Forfeiture, Foreclosure, and Sale A $15 collection fee is added in October.
If the debt isn’t paid by March 1 of the following year, the property is forfeited to the county treasurer. Forfeiture brings a $175 fee, $30 in recording fees, and an interest rate that jumps to 1.5 percent per month, applied retroactively to the original delinquency date.14Wayne County Treasurer. Forfeiture/Foreclosure Timeline That retroactive recalculation alone adds a significant chunk to the balance.
After forfeiture, the county files for judicial foreclosure. Show cause and judicial foreclosure hearings are typically held between October and February. If the balance isn’t cleared by the end of March, the circuit court enters a judgment of foreclosure, and on April 1 the owner loses all rights. Title transfers to the county treasurer, and the property is sold at public auction later that year. Under a 2020 Michigan Supreme Court ruling, former owners are entitled to any surplus sale proceeds beyond the amount owed in taxes, interest, penalties, and fees, but you have to file a “Notice of Intent to Claim Remaining Foreclosure Proceeds” form before the county’s deadline.
The full cycle from first missed payment to loss of the property runs about two and a half years. The fees and compounding interest make the debt grow fast: a $3,000 delinquency can easily become $5,000 or $6,000 by the time foreclosure looms.
Payment Plans for Delinquent Taxes
If you’ve already fallen behind, the Wayne County Treasurer offers several payment plans that can stop the foreclosure clock as long as you stay current on the agreed schedule.15Wayne County Treasurer. Payment Plans
- The Interest Reduction Stipulated Payment Agreement (IRSPA) is available to owner-occupants with a Principal Residence Exemption on file. It cuts the interest rate from 18 percent to 6 percent and bundles all delinquent years into one schedule.
- The Regular Stipulated Payment Agreement (REGSPA) is open to everyone, including owners of investment or non-owner-occupied properties. It keeps foreclosure at bay as long as payments are made on schedule, though the standard interest rate applies.
- The Distressed Owner/Occupant Extension (DOOE) is designed for homeowners with documented financial hardship. You have to own and occupy the property and provide proof of residency. Interest remains at 18 percent per year.
Veterans with an honorable discharge (documented by DD-214 or discharge certification) and active first responders employed as police officers, firefighters, or EMS personnel can enter a payment plan with no down payment. For questions about which plan fits your situation, the Wayne County Treasurer’s office can be reached at 313-224-5990.
