Ann Arbor Property Tax Rate and Millage Breakdown

The total Ann Arbor Property Tax rate is expressed in mills, with one mill equal to one dollar per one thousand dollars of taxable value. The composite rate combines city, Washtenaw County, school district, and special district levies into a single number applied to every parcel. For fiscal year 2026, the citywide composite millage is estimated at 48.32 mills (subject to final equalization), which ranks among the highest effective rates in Michigan.

Washtenaw County carries a significant share of the millage, and the Ann Arbor Public Schools operating and debt levies add further weight to the composite. The city operating millage, the Ann Arbor Area Transportation Authority, and the Washtenaw Intermediate School District each add smaller increments that, when stacked, push the composite rate well above the state average. Voters approve each component levy through separate ballot proposals, and each entity sets its own rate independently.

Because mills shift after each election cycle, the rate a property owner pays can change even when the millage formula stays the same. The Washtenaw County Equalization Department publishes a complete millage comparison report each year that breaks down every levy by school district, township, and city. That document lets property owners see exactly which entity receives a share of their bill.

• One mill equals $1.00 of tax per $1,000 of taxable value.
• The composite rate applies to taxable value, not SEV or market price.
• Each millage component is approved by voters in separate elections.
• Millage rates change after each February or August election cycle.

Taxable Value and SEV in Ann Arbor

Michigan uses two values on every property record: the State Equalized Value (SEV) and the taxable value. SEV reflects fifty percent of the assessed market value, set annually by the local assessor based on sales studies. Taxable value starts at the SEV in the year following a sale or transfer and then rises each year by the rate of inflation or five percent, whichever is lower.

The Ann Arbor Property Tax bill is calculated using taxable value, not SEV. This means long-term owners often pay tax on a number far below today’s market value. When ownership changes, Proposal A causes the taxable value to uncap and reset to the current SEV, sometimes producing a sharp jump in the next bill.

Reviewing both values through the city parcel viewer and BS&A Assessing platform helps owners spot errors early. A mistake in SEV can trigger a taxable value error the following year, multiplying the impact across the cap calculation. Owners who catch the discrepancy before the March Board of Review have a much stronger position than those who wait for the July or December boards.

• SEV updates every year on the tax roll.
• Taxable value caps at the lower of inflation or 5%.
• Transfers of ownership uncap the taxable value to current SEV.
• Review both numbers annually through the city parcel viewer.

How to Calculate an Ann Arbor Property Tax Bill

Most property owners use a simple three-step process to estimate their Ann Arbor Property Tax bill. First, locate the taxable value through the BS&A parcel page. Second, confirm the total millage rate for the parcel’s school district and special districts. Third, multiply the taxable value by the millage rate, then divide by 1,000.

For a rough example, a home with a taxable value of $200,000 and a composite millage of 48.32 would owe approximately $9,664 in annual Ann Arbor Property Tax before any exemption credits. Adding the Principal Residence Exemption removes 18 mills from the school operating levy, lowering the bill to roughly $6,064 for an owner-occupied home.

The exact bill always comes from the City Treasurer’s office, not from an online calculator. Third-party estimators help with budgeting, but the official summer and winter tax bills reflect final millage, exemption status, and any special assessments recorded against the parcel.

• Use taxable value, not market value, when estimating.
• Apply PRE credit if the property is the owner’s principal residence.
• Include any special assessments for sidewalks, sewers, or lighting.
• Confirm the final amount on the actual bill issued by the Treasurer.

Ann Arbor Property Tax Due Dates and Online Payment

Ann Arbor Property Tax bills are issued twice a year, with a summer levy and a winter levy. The summer bill covers the local school operating millage and the winter bill covers the city, county, and other levies. Each bill has its own due date and penalty schedule. Refer to the most recent tax bill or the City Treasurer’s office for the exact due dates applicable to the current tax year.

Payment is accepted online through the city portal, by mail, or in person at the Treasurer’s office. The BS&A platform supports property data review, and the City Treasurer accepts payments through the city’s official payment channels. Property owners who pay on time avoid penalties and protect their escrow account from shortages.

• Two bills per year: a summer levy and a winter levy, each with its own due date.
• Online payment: accepted through the city’s official payment portal.
• Mail payment: accepted at the Treasurer’s office mailing address listed on the bill.
• In-person payment: accepted at the Treasurer’s office during regular business hours.

Late payments trigger interest and penalties that compound monthly. Owners enrolled in escrow should confirm that their mortgage servicer receives the bill directly from the Treasurer to avoid double-payment. A small billing error caught early can save several hundred dollars in penalty charges by year-end.

Escrow Accounts and Ann Arbor Property Tax

Most homeowners with a mortgage pay their Ann Arbor Property Tax bill through an escrow account managed by their loan servicer. The servicer collects a portion of the estimated annual bill with each mortgage payment, then pays the Treasurer when each bill comes due. This setup spreads the cost across twelve monthly installments instead of two large payments.

Servicers review escrow accounts annually and adjust the monthly collection based on the prior year’s actual bill plus a small cushion. A spike in the Ann Arbor Property Tax bill, such as a transfer of ownership or removal of an exemption, can trigger an escrow shortage that the owner must repay over the next twelve months.

• Escrow spreads annual tax across monthly mortgage payments.
• Servicers adjust escrow yearly based on actual bill.
• Tax increases after a sale can trigger escrow shortage.
• Owners can request an escrow analysis to confirm accuracy.
• Large tax bills may push the mortgage payment up.

Homeowners with high equity who have paid off their mortgage should set up their own escrow savings account. Setting aside one-twelfth of the annual Ann Arbor Property Tax bill each month creates the same smoothing effect and prevents a sudden large outflow when the bill arrives.

Exemptions Available for Ann Arbor Homeowners

Michigan law offers several exemptions that lower the Ann Arbor Property Tax bill for qualifying owners. The Principal Residence Exemption (PRE) is the most common and removes 18 mills from the school operating levy. To qualify, the owner must own and occupy the home as their primary residence on or before the filing deadline for the tax year.

Other exemptions target specific groups. The senior freeze freezes the taxable value for owners aged 65 or older who meet income limits. The disabled veteran exemption removes the entire school operating tax for veterans with a service-connected disability rating from the VA. The poverty exemption can reduce or eliminate taxes for owners facing documented financial hardship.

Exemptions must be filed with the Assessor’s Office by the deadline published each year. PRE can be claimed once and stays active until the property is sold or the owner stops using it as a primary residence. Senior and disabled veteran exemptions require annual or periodic renewal, with income documentation attached.

• File PRE by the published deadline for the tax year at the Assessor’s Office.
• Senior exemption requires annual income verification.
• Disabled veteran exemption needs VA documentation.
• Poverty exemption requires hardship proof and Board of Review approval.

Property Tax Relief and Senior Support Programs

Beyond standard exemptions, Ann Arbor Property Tax relief options exist for low-income seniors, low-income homeowners, and qualifying disabled individuals. The homestead property tax credit is filed with the Michigan Treasury on the state income tax return and provides a refundable credit that can offset part of the annual bill.

Senior owners with limited income can also apply for a deferral program through the state that allows them to postpone Ann Arbor Property Tax payments until the property is sold. Interest accrues on the deferred amount, but the immediate cash flow relief helps owners on a fixed income stay in their homes.

• Homestead Property Tax Credit filed with state return.
• Senior deferral program delays payment until sale.
• Disabled homeowner credit applies to qualifying individuals.
• Local hardship deferral handled by the Treasurer.
• Income limits apply to most relief programs.

Homeowners applying for any relief program should gather income statements, asset records, and proof of hardship before meeting with the Assessor’s Office. Many programs require annual recertification, and missed paperwork can cause a sudden reinstatement of the full bill.

Filing an Ann Arbor Property Tax Appeal

Property owners who believe their Ann Arbor Property Tax assessment is too high can appeal to the March Board of Review. The first step is reviewing the property record card on the BS&A Assessing platform to confirm square footage, bedroom count, and features match the actual home. Errors in any of these fields often support a successful reduction.

The appeal letter must be filed with the Board of Review by the published deadline for the March session. Supporting evidence includes recent comparable sales, a private appraisal, or photos of conditions that reduce value. A face-to-face hearing is optional but often helps the board understand the argument.

• Review property record card for errors before appealing.
• Gather three to five comparable sales within the same neighborhood.
• Submit a written appeal by the published March Board of Review deadline.
• Attend the Board of Review hearing if possible.
• If denied, appeal further to the Michigan Tax Tribunal within 30 days.

Appeals that cite clear comparable sales at lower prices have the highest success rate. Overstated features, such as an extra bathroom or finished basement that does not exist, are common assessment errors worth flagging. A successful appeal refunds the overpayment and lowers the taxable value for the next year as well.

Ann Arbor Property Tax Reassessment Process

The City of Ann Arbor conducts an annual assessment review based on sales activity from the prior year. When market values rise faster than five percent, the SEV on every property increases the following December. When sales stagnate or fall, the assessor may lower SEV to reflect current reality.

Reassessment notices go out in late December to every property owner. The notice lists the new SEV, the new taxable value, and any exemption changes. Owners have until the following March Board of Review to challenge the reassessment if the new value exceeds the actual market value of the property.

• Reassessment notices arrive in late December each year.
• New SEV reflects prior-year sales studies.
• Taxable value still capped by inflation or 5%.
• Property transfers uncap the taxable value.
• Owners can appeal the new SEV at the March Board of Review.

Washtenaw County equalization reviews each municipality’s assessments to keep values consistent across the region. If Ann Arbor’s SEV ratio drifts above or below 50%, the county adjusts the roll, which can shift individual parcels even when no sale occurred. Tracking these equalization steps helps owners predict changes before the bill arrives.

Brownfield, DDA, and Special Tax Districts in Ann Arbor

Several areas of Ann Arbor sit inside special tax districts that capture a portion of new property tax growth for redevelopment. The Downtown Development Authority (DDA) captures tax increment from parcels in the central business district to fund public improvements, streetscape work, and parking structures. Brownfield zones capture incremental tax for environmental cleanup at former industrial sites.

Owners in these districts still pay the full Ann Arbor Property Tax bill, but a portion of the growth above a base year flows to the authority instead of to schools, city, or county. For most individual owners, the impact is small and reflected in the millage breakdown on the BS&A parcel page.

New construction in these districts triggers capture starting the year the project reaches the tax roll. Owners planning a major build should consult the city’s planning department to estimate the capture impact on the project’s first-year taxes.

• DDA captures growth in the downtown boundary.
• Brownfield zones cover former industrial sites.
• TIF districts support infrastructure near new development.
• Special assessments fund sidewalks, sewers, and lighting.

Delinquent Taxes, Penalties, and Foreclosure Prevention

An Ann Arbor Property Tax bill becomes delinquent if unpaid by the due date printed on the bill. Interest and penalties accrue on the unpaid balance until it is cleared. Under Michigan’s delinquent tax process, properties with multi-year delinquencies may be subject to forfeiture and eventual foreclosure by the county treasurer. Property owners should refer to the official Washtenaw County Treasurer and Michigan Department of Treasury guidance for the specific timelines applicable to the current year.

Homeowners facing delinquency should contact the Treasurer’s office immediately to discuss payment plans, hardship deferrals, or partial-pay agreements. Federal mortgage servicers also offer loss-mitigation options that can bring the loan current and cure the tax default. Acting quickly almost always avoids forfeiture.

• Interest and penalties accrue on any unpaid balance after the due date.
• Forfeiture and foreclosure follow the timelines set by Michigan statute and the county treasurer.
• Payment plans are available through the Treasurer’s office.
• Hardship deferral is possible for documented financial crisis.

Investors and landlords who hold rental property must keep taxes current to protect tenants and avoid surprise liens. Many servicers require a tax holdback at closing, but that holdback only lasts a few months and should not replace active payment management.

Commercial vs Residential Property Tax in Ann Arbor

Commercial parcels in Ann Arbor pay the same composite millage rate as residential parcels but rarely claim the Principal Residence Exemption. A small office building or retail storefront therefore pays the full 48.32 mills on its taxable value, producing a much higher effective rate than a neighboring home that claims PRE.

Industrial parcels in designated districts may qualify for the Industrial Facilities Tax Exemption, which caps the taxable value at half the SEV for a set number of years. Owners renovating or expanding a facility should review eligibility before completing construction to lock in the savings from the first full year of operation.

Condo owners occupy a hybrid situation: they pay property tax on the individual unit but receive an allocation of the master association’s bill. Reviewing the condo bylaws and the master association budget helps owners understand how their share of common-area assessments appears on the bill.

• Commercial owners rarely qualify for PRE.
• NEZ and Renaissance Zone credits exist in select areas.
• Industrial owners should check IFT eligibility before building.
• Condo owners share master association assessments.

Rental Property and Apartment Tax Considerations

Landlords owning rental homes and apartment buildings in Ann Arbor pay the full composite millage because the property is not their primary residence. Owners who live in one unit of a duplex and rent the other can claim PRE only on the owner-occupied portion. The rental half is taxed at the full rate.

Apartment owners face the same Proposal A rules as other property owners. Buying a rental triggers taxable value uncapping to current SEV. Holding for many years allows the cap to control annual increases, supporting predictable cash flow planning. Selling again triggers another uncapping for the new buyer.

• Rental homes taxed at full composite millage.
• Duplex owners can split PRE between units.
• Purchase triggers taxable value uncapping.
• Long hold periods allow the inflation cap to control growth.
• Rental income must cover taxes plus debt and expenses.

Tenant leases should pass property tax through to the tenant as a reimbursement or include it in the rent. Many Ann Arbor landlords build tax cost into monthly rent and reconcile annually against the actual bill. This approach protects cash flow when millages shift after elections.

Property Tax Proration at Closing in Ann Arbor

Ann Arbor Property Tax proration at closing splits the annual bill between buyer and seller based on the closing date. The title company or closing attorney calculates the seller’s share using days of ownership in the tax year and credits the buyer for the remaining days. This protects both parties from paying the full annual amount when ownership changes mid-year.

If the most recent bill is unpaid at closing, the closing agent pays the Treasurer directly from the seller’s proceeds. The buyer then receives a credit for the post-closing portion of that payment. If a new bill has not yet been issued, the proration uses the prior year’s bill as an estimate and reconciles after the next bill posts.

• Proration splits the annual tax based on closing date.
• Seller’s share covers days of ownership before closing.
• Buyer’s share covers days of ownership after closing.
• Unpaid prior bills are paid at closing from seller proceeds.
• Estimated prorations reconcile after the next bill posts.

Buyers should confirm the proration method with their lender and closing agent well before the signing date. A small miscalculation on a high-value property can create a four-figure surprise at closing or afterward when the next bill reconciles.

Comparing Ann Arbor Property Tax to Nearby Cities

The Ann Arbor Property Tax composite millage of 48.32 is among the highest in Michigan, driven mostly by the strength of the local school district and the Washtenaw County levy stack. Washtenaw County has the highest median property tax bill in Michigan at $5,827, and the median Ann Arbor tax bill exceeds the state median by a wide margin.

Nearby cities and townships typically carry lower composite millages, often reflecting smaller school operating levies and fewer overlapping special districts. For homeowners who commute to Ann Arbor but live in a lower-tax township, the savings on a mid-priced home can be substantial. Refer to the Washtenaw County equalization millage comparison report for the specific composite rate in each neighboring community.

Relocating from a lower-tax city into Ann Arbor triggers a Proposal A uncapping because ownership transfers. Buyers should budget for the new SEV-based taxable value in the first full year of ownership rather than assuming the prior owner’s capped bill.

• Ann Arbor millage sits well above the state average.
• Nearby suburbs typically run lower composite rates.
• Washtenaw County has Michigan’s highest median tax bill.
• Transfers of ownership trigger taxable value uncapping.
• Budget for a higher first-year bill after purchase.

Property Tax Affordability and Planning Tips

Ann Arbor Property Tax affordability depends on household income, mortgage size, and fixed expenses. A common rule suggests keeping total housing costs, including tax and insurance, below thirty percent of gross monthly income. On a $400,000 home with a high composite millage, taxes alone can exceed $1,000 per month.

Smart planning reduces the load over time. Filing for PRE, claiming the senior freeze at age 65, appealing an inflated assessment, and reviewing the BS&A record card each year are all steps that produce real savings. Owners should also revisit exemptions whenever life changes, such as retirement or a move in with a relative.

• Keep total housing cost below 30% of gross income.
• File for every exemption for which you qualify.
• Review the BS&A record card each December.
• Appeal inflated assessments at the March Board of Review.
• Update exemption status after retirement or household change.

Long-term owners often see their Ann Arbor Property Tax bill rise slowly because the inflation cap protects the taxable value. Owners should still plan for the eventual uncapping event, such as a future sale, when the next buyer will face the full SEV-based bill on day one.
