How Washtenaw County Property Tax Rates Are Calculated
Property tax bills in Washtenaw County are derived by multiplying the property’s Taxable Value by the total millage rate applicable to that specific parcel location. Millage rates are set by overlapping taxing authorities, including the county, township or city, school district, intermediate school district, and community college. Each authority sets its own rate annually based on operating budgets and voter-approved millage requests. The sum of all these rates produces the total millage used to compute the final tax bill.
Taxable Value differs from market value. The Principal Residence Exemption, Special Act Rollback, and other statutory adjustments lower Taxable Value below the State Equalized Value (SEV). Property owners can use the formula below to estimate their annual tax obligation.
| Component | Description | Example Value |
|---|---|---|
| State Equalized Value (SEV) | Assessed value adjusted to 50% of market value | $300,000 |
| Taxable Value | Value used for tax calculation after exemptions and caps | $250,000 |
| Total Millage Rate | Combined rate from all local authorities (mills) | 45.0000 mills |
| Annual Tax Bill | Taxable Value ÷ 1,000 × Millage Rate | $11,250 |
Use the Washtenaw property tax calculator at the Equalization Department’s online portal to run precise numbers for your parcel. The calculator accepts SEV, Taxable Value, and applicable exemptions to produce a real-time bill estimate.
Ann Arbor Real Estate Tax Assessment Process
Local assessing officers in Ann Arbor and other Washtenaw County jurisdictions conduct annual assessments of every real property parcel within their boundaries. Assessors examine sales data, property characteristics, building permits, and economic conditions to determine the True Cash Value (TCV) of each parcel. TCV represents 50% of the market value, which becomes the State Equalized Value (SEV) after adjustment by the county Equalization Department.
Taxable Value is calculated separately using the Consumer Price Index (CPI) cap, which limits annual increases to 5% or the rate of inflation, whichever is lower. The cap applies to all property classes except properties that transferred ownership in the prior year. Newly transferred parcels reset to the SEV in the year following the sale.
| Assessment Step | Responsible Party | Frequency |
|---|---|---|
| Parcel Inspection | Local Assessor | Annual or rotating cycle |
| True Cash Value Determination | Local Assessor | Annually (study period) |
| State Equalized Value (SEV) | Washtenaw County Equalization Department | Annually |
| Taxable Value Calculation | Local Assessor | Annually with CPI cap |
| Tax Bill Issuance | Local Treasurer / County | Summer and Winter |
Property owners can view the assessed values for their parcels through the public search portal listed in the first section of this page.

Homestead Exemption in Washtenaw County
The Homestead Property Tax Exemption lowers the school operating tax levy on a primary residence owned and occupied by the applicant. Filing the exemption reduces the Taxable Value used in millage calculations, resulting in a lower annual tax bill. Michigan allows up to two methods for filing: a recorded deed with the property identified as a homestead, or an affidavit filed directly with the local assessor.
To qualify, the property must be the owner’s principal residence as of January 1 of the tax year. Renters cannot claim the exemption on behalf of landlords. New owners must file by the deadline established by their local township, city, or village in Washtenaw County.
Required documentation for the Washtenaw County homestead exemption:
- Michigan Driver’s License or State ID showing the property address
- Voter registration card listing the property address
- Federal or state income tax return showing the property as the primary address
- Vehicle registration matching the property address
Homeowners can claim the exemption through the Michigan Treasury Online portal or by submitting Form 2368 to the local assessor. Annual filings are not required once the exemption is active, except for changes in ownership or occupancy status.
Property Tax Rebates and Deferral Programs
Michigan offers two primary financial relief programs for property owners facing hardship: the Homeowner Property Tax Credit (HPTC) and the Property Tax Deferral Program. Both programs help Washtenaw County residents reduce or postpone property tax obligations. Eligibility is based on household income, age, disability status, and property classification.
| Program | Eligible Applicants | Maximum Benefit |
|---|---|---|
| Michigan Homeowner Property Tax Credit (HPTC) | Homeowners with household income under $60,000 | Up to $1,500 credit per year |
| Property Tax Deferral Program | Seniors 65+, disabled adults, or low-income owners | Postponed taxes paid at sale or death |
| Disabled Veterans Exemption | Veterans with 100% service-connected disability | Full property tax exemption |
| Homestead Property Tax Exemption | Owner-occupied primary residences | School millage reduction (up to 18 mills) |
Property tax rebates for Washtenaw residents are filed through the Michigan Department of Treasury using Form MI-1040CR. The deferral program requires an annual application submitted to the State Treasury office. Contact the Washtenaw County Equalization Department at equalization@washtenaw.org to begin a deferral application or learn about HPTC eligibility.
Washtenaw Land Value Tax and School District Levies
Washtenaw County does not operate a countywide Land Value Tax (LVT), but several local municipalities and school districts levy property taxes at separate rates on land and improvements. The Land Value Tax in qualifying areas taxes the unimproved value of a parcel at a higher rate than the value of structures. School district taxes are levied separately and represent a substantial portion of the total millage rate in many Washtenaw County areas.
Sample millage breakdown for a typical Ann Arbor residential parcel:
| Taxing Authority | Approximate Millage | Purpose |
|---|---|---|
| Washtenaw County Operations | 4.5000 mills | General county services |
| Ann Arbor Public Schools | 18.0000 mills (PRE reduces this) | K-12 education |
| Washtenaw Intermediate School District | 4.0000 mills | Special education and vocational programs |
| City of Ann Arbor | 6.0000 mills | Police, fire, and infrastructure |
| Washtenaw Community College | 2.5000 mills | Higher education funding |
| Total Combined Millage | 35.0000 mills | Full annual tax levy |
School district millage rates vary across the county based on voter-approved sinking fund millages, bond issues, and operating expenses. Check the property tax search portal for the exact millage rate applied to your parcel.
Property Tax Appeal Process in Washtenaw
Property owners who believe their assessed value exceeds market value may file an appeal with the March Board of Review. The Board operates in each township, city, and village in Washtenaw County. Appeals must be filed by the published deadline, which typically falls on the third Monday in March. Written appeals and supporting evidence are required.

The Small Business Personal Property Tax Exemption allows businesses to deduct the first $180,000 of true cash value of personal property from taxable value. Forms 5076 and 5076AF must be filed with the local assessor by February 20 of each tax year.

Property Tax Delinquency and Tax Lien Certificates
Property taxes in Washtenaw County become delinquent on March 1 following the year of the levy. Unpaid taxes are subject to interest charges of 1% per month and a 4% late penalty on the unpaid balance. Continued non-payment triggers forfeiture proceedings, with the property subject to seizure by the county treasurer after a statutory waiting period of two years (or three years for homestead properties).
Tax lien certificates may be purchased by investors for properties with delinquent taxes. The Washtenaw County Treasurer’s office conducts annual tax lien sales, providing investors with the right to collect delinquent taxes plus interest. Liens are redeemed by the property owner through full payment of back taxes, penalties, and interest before the property is foreclosed.
| Delinquency Stage | Timeframe | Action Taken |
|---|---|---|
| Original Due Date | February 14 (Winter) / September 14 (Summer) | Tax bill issued |
| Delinquency Date | March 1 | Interest and penalty begin |
| Forfeiture | March 1 (Year 2 for non-homestead, Year 3 for homestead) | Property forfeited to county |
| Tax Lien Sale | Annually (typically May) | Delinquent parcels sold to investors |
| Judicial Foreclosure | 2-3 years after forfeiture | Court action to transfer title |
Property owners facing delinquency can avoid forfeiture by entering a payment plan with the Washtenaw County Treasurer’s office. Call (734) 994-2511 for information on repayment options.
