Wayne County property tax bills arrive twice a year, built from your home’s Taxable Value and due September 14 for the summer levy and February 14 for the winter levy. Miss February 28, and your unpaid balance transfers to the Wayne County Treasurer with a 4 percent fee attached and interest running at 1 percent per month. Everything below walks through the deadlines, the exemptions and credits that can lower what you owe, how to appeal an assessment you believe is too high, and the three-year timeline that ends in foreclosure if the debt is never paid.
Payment Deadlines You Cannot Miss
Summer taxes become a lien on July 1 and are due by September 14. Winter taxes become a lien on December 1 and are due by February 14.1State of Michigan. Frequently Asked Questions – Property Tax Interest starts accruing the day after each deadline. Some cities set different summer due dates through their charters, so check with your local treasurer if yours is unclear.
February 28 is the hard cutoff. Any winter taxes still unpaid on that date become delinquent on March 1 and transfer from your local city or township treasurer to the Wayne County Treasurer.2City of Detroit. Delinquent Property Tax Information Once that transfer happens, you can no longer pay at the local level and have to deal with the county directly.
Summer Deferment for Qualifying Homeowners
Michigan allows certain homeowners to defer the summer payment to February 15 without penalty. You qualify if your total household income is $40,000 or less and you are age 62 or older, totally and permanently disabled, or an eligible veteran or surviving spouse. File the deferment application with your local treasurer before the summer due date.
How Your Bill Is Calculated
Three figures appear on your assessment notice. The Assessed Value equals 50 percent of your property’s estimated market worth. The State Equalized Value adjusts that number after the county applies equalization factors so communities stay uniform. Your actual bill, though, comes from a third figure: the Taxable Value.
Michigan’s Proposal A, passed by voters in 1994, caps how fast Taxable Value can rise each year at the lesser of 5 percent or the Consumer Price Index inflation rate. The cap holds until the property changes hands. For 2026, the state-calculated Inflation Rate Multiplier is 1.027, which caps Taxable Value increases at 2.7 percent for properties that did not sell.3City of Detroit. Bulletin 14 of 2025 – Inflation Rate Multiplier for 2026 When a property sells, the Taxable Value resets to the Assessed Value the following year. That is why long-time owners often pay far less than a new buyer of an identical home next door.
Exemptions and Credits That Lower What You Owe
Principal Residence Exemption
If you own and live in the home as your primary residence, the Principal Residence Exemption shields you from up to 18 mills of local school operating taxes. On a home with a Taxable Value of $100,000, that works out to roughly $1,800 a year.4State of Michigan. Principal Residence Exemption Without it, you pay the full non-homestead millage that applies to rentals and second homes.
File the affidavit with your local tax collecting unit by June 1 to apply to the upcoming summer levy, or by November 1 for the winter levy.5Michigan Legislature. Michigan Compiled Laws 211.7cc – Principal Residence Exemption If you move out or start renting the property, file a rescission form. Failing to rescind can trigger back taxes, interest, and penalties once the assessor catches it.
Homestead Property Tax Credit
Michigan residents who own or rent their principal residence can claim the Homestead Property Tax Credit on their state income tax return using Form MI-1040CR. For 2026, you qualify if your total household resources are $71,500 or less and your home’s taxable value is $165,400 or lower.6State of Michigan. Michigan Taxpayers Encouraged to Check Eligibility for Homestead Property Tax Credit The credit offsets part of the property taxes (or rent equivalent) that exceed a percentage of household income. Renters qualify too, which many people miss.
Poverty Exemption
Homeowners who cannot afford property taxes due to poverty can apply for a partial or full exemption under MCL 211.7u. You must file annually with your local assessor or Board of Review, and each community sets its own income guidelines and asset limits.7State of Michigan. Poverty Exemption Contact your city assessor’s office for the thresholds and required documents where you live.
How to Pay
Before taxes go delinquent, you pay your local city or township treasurer. Each municipality takes payments by mail, in person, and usually online. After March 1, delinquent balances go through the Wayne County Treasurer’s Office.
The Treasurer’s online portal at pta.waynecounty.com accepts electronic check and credit card payments.8Wayne County Treasurer. Pay Taxes Online Credit card transactions carry a convenience fee from the processor. You can also mail a payment to the lockbox address on your statement, visit the Treasurer’s office in Detroit for an immediate stamped receipt, or use one of the payment kiosks positioned around the county, which take cash, checks, and cards. Keep your confirmation number or receipt. That record is what protects you if a payment is misapplied.
Appealing an Assessment You Believe Is Too High
Your first stop is the local Board of Review. Every city and township holds Board of Review hearings in March, and you must file a protest during that window to preserve any further appeal. You can appear in person or submit a written appeal with your name, parcel number, and evidence supporting a lower value. The burden is on you, so bring comparable sales data, photos of property conditions, or a professional appraisal if the case justifies the cost.
If the Board denies your protest, residential and agricultural owners can appeal to the Michigan Tax Tribunal by July 31 of the same tax year. Properties with a Principal Residence Exemption of at least 50 percent can file in the Tribunal’s small claims division at no cost.
Skipping the March Board of Review is the most common mistake. For residential property, that protest is a prerequisite to the Tax Tribunal. Miss it and you lose the right to challenge your valuation for that year.
What Happens When Taxes Go Unpaid
Michigan law runs a three-year clock from the moment taxes become delinquent to the point where you lose the home. The costs compound quickly, and the final deadline is absolute.
Year One: Delinquency
On March 1, unpaid taxes transfer to the Wayne County Treasurer. A 4 percent county administration fee is added immediately, plus interest at 1 percent per month (noncompounded) calculated from the original date the taxes became delinquent.9Michigan Legislature. Michigan Compiled Laws 211.78a – Delinquent Property Tax On a $3,000 bill, that administration fee alone adds $120, and every month of delay adds another $30 in interest.
If you’ve already fallen behind, the Wayne County Treasurer’s Office offers payment plans for delinquent taxes and hardship extensions for homeowners facing financial emergencies. The Treasurer also works with community organizations that provide direct financial assistance to qualifying residents. Enrollment details are on the Treasurer’s website or available by contacting the office directly.
Year Two: Forfeiture
If the debt is still unpaid by March 1 of the next year, the property forfeits to the county treasurer. The county adds a $175 fee per property and records a Certificate of Forfeiture with the Register of Deeds within 45 days, which clouds your title and makes selling or refinancing nearly impossible.10Michigan Legislature. Michigan Compiled Laws 211.78g – Property Delinquent or Forfeited An additional 0.5 percent per month interest begins accruing on top of the original 1 percent monthly rate, bringing the combined burden to 1.5 percent per month. The original 1 percent runs from the initial delinquency date; the additional 0.5 percent is computed from the March 1 preceding forfeiture.
Year Three: Foreclosure
If the balance persists into the third year, the Wayne County Treasurer petitions the Circuit Court for foreclosure. The court enters a judgment by March 30, and the owner has until March 31 to pay the entire amount owed, including all accumulated fees, interest, and penalties.11Michigan Legislature. Michigan Compiled Laws 211.78k – Final Judgment on Petition for Foreclosure Miss that deadline, and title vests absolutely in the foreclosing governmental unit. There is no further extension and no practical legal mechanism to reverse the loss once the redemption period expires.
Claiming Surplus Equity After a Foreclosure Sale
Before 2020, Michigan counties could auction a foreclosed property and keep every dollar, even when the home was worth far more than the unpaid taxes. The Michigan Supreme Court’s ruling in Rafaeli, LLC v. Oakland County ended that practice, and the legislature amended the General Property Tax Act to let former owners claim surplus proceeds. The U.S. Supreme Court reinforced the principle in Tyler v. Hennepin County, holding that governments violate the Fifth Amendment’s Takings Clause when they seize property value exceeding the tax debt.
If Wayne County sells a foreclosed property for more than the total taxes, interest, penalties, and fees owed, the former owner can file a claim for the surplus. Claims must be brought within two years of the foreclosure judgment.12Wayne County Treasurer.
