How to Look Up Ann Arbor Property Tax and Assessment Information
Before paying or estimating taxes, look up the property record and confirm the correct parcel, taxable value, and tax year. This is especially important for recent buyers, landlords, escrow users, and properties with multiple addresses or unit numbers.
1
Start from the official City of Ann Arbor website
Use the city site before using a payment or records vendor.
▾
Open the official City of Ann Arbor website and navigate to Treasury, property taxes, or assessing. Starting from the official city website helps avoid unrelated payment websites.
2
Use the assessing record to confirm taxable value
Taxable value matters more than market value for tax calculation.
▾
Go to City of Ann Arbor Assessing to find property assessment resources. Look for taxable value, assessed value, property classification, ownership, and exemption information.
3
Match the exact parcel before paying
Address-only searches can cause mistakes.
▾
Compare owner name, parcel number, property address, tax year, and bill type. For condos, duplexes, rentals, recently sold properties, and trust-owned properties, parcel verification is more reliable than address search alone.
4
Check county records if the tax is delinquent
Returned taxes may move from city to county collection.
▾
If the tax bill is no longer payable through city collection, check the Washtenaw County Treasurer for delinquent tax guidance.
How to Pay Ann Arbor Property Taxes Online Safely
Property tax payment pages often appear in search results, but the safest route is to begin from official City of Ann Arbor treasury resources and confirm every bill detail before submitting payment.
1
Open Ann Arbor’s official property tax or treasury page
Do not start from an unrelated bill-pay website.
▾
Start from the City of Ann Arbor Property Taxes / Treasury page. If the city redirects to an official payment vendor, confirm the vendor is linked from the city page before entering payment information.
2
Confirm summer or winter tax bill
Ann Arbor property owners may see more than one tax bill cycle.
▾
Check whether you are paying a summer tax bill, winter tax bill, special assessment, prior-year balance, or delinquent amount. If you are unsure, contact city treasury resources through a2gov.org before paying.
3
Review payment fees and posting rules
Card and e-check rules can vary by payment processor.
▾
Before submitting, review the final amount, convenience fee, payment method, processing date, and posting language shown on the official payment screen. Keep a receipt or confirmation number.
4
Check escrow before paying yourself
Mortgage companies may already be scheduled to pay.
▾
If your mortgage servicer escrows taxes, confirm whether the lender has paid, scheduled payment, or expects you to pay a specific bill. Save lender correspondence and city payment confirmation to avoid duplicate-payment confusion.
5
Use county Treasurer for delinquent tax only
Delinquent tax handling can move from city to county.
▾
If the taxes are returned delinquent or the city can no longer accept payment, use the official Washtenaw County Treasurer route for next steps.
How to Calculate Ann Arbor Property Tax Online or Manually
A practical Ann Arbor property tax estimate uses Michigan’s taxable value system. The basic formula is: Taxable Value × Total Millage Rate ÷ 1,000 = Estimated Property Tax. The final official bill may also include fees, special assessments, penalties, and adjustments.
Step 1: Find taxable value
Use City Assessing or your assessment/tax record to find taxable value.
Step 2: Find total mills
Review your current city, county, school, library, state education, transit, and other millage lines from the official bill.
Step 3: Divide by 1,000
Multiply taxable value by total mills, then divide by 1,000 to estimate taxes before adjustments.
| Example Item | How to Use It | Example |
|---|---|---|
| Taxable value | Find on official assessment/tax record. | $150,000 taxable value |
| Total millage | Add all applicable millage lines from the official bill. | 50 mills |
| Formula | Taxable value × mills ÷ 1,000. | $150,000 × 50 ÷ 1,000 = $7,500 |
| Final bill check | Compare with city bill for fees, special assessments, and adjustments. | Official bill may differ from estimate. |
1
Do not calculate from market price only
Michigan taxes usually use taxable value, not asking price.
▾
A home’s sale price, estimated market value, assessed value, and taxable value are not always the same. Start with taxable value from official city assessing resources.
2
Be careful after buying a property
Taxable value may uncap after a transfer.
▾
In Michigan, a property transfer can cause taxable value to uncap for the following tax year. Buyers should not estimate future taxes only from the seller’s previous bill. Review Michigan property tax guidance at Michigan.gov property tax resources.
3
Separate summer and winter bills
A partial bill estimate may not show the full annual tax.
▾
Ann Arbor property taxes may appear in summer and winter bills. When estimating annual cost, make sure you are considering all applicable annual tax bills, not just one seasonal bill.
Ann Arbor Property Tax Rates: Why Your Bill Includes More Than City Taxes
Ann Arbor property taxes can include several taxing authorities and voter-approved millages. That is why a property tax bill is not simply “the city rate.” Your final total depends on property type, taxable value, school district, millage lines, exemptions, and special assessments.
| Bill Component | What It Means | Who to Contact |
|---|---|---|
| City millage | City of Ann Arbor operating or voter-approved city tax lines. | City of Ann Arbor |
| County millage | Washtenaw County tax lines and county-wide items. | Washtenaw County |
| School taxes | School district and state education tax items can be a major part of the bill. | School district for budget context; city/county for tax bill collection status. |
| Library / transit / other millages | Voter-approved local items may appear depending on district and property location. | The listed agency or official tax bill contact. |
| Special assessments | Parcel-specific charges for improvements or services may appear separately. | City treasury or the department listed for the assessment. |
Ann Arbor Property Tax Due Dates, Summer/Winter Bills and Late Payment Risk
Ann Arbor property tax bills are commonly organized into summer and winter cycles. Due dates, penalty timing, and delinquent transfer rules should always be confirmed on the current official bill or city treasury page.
| Tax Stage | What to Check | Practical Action |
|---|---|---|
| Summer tax bill | Bill date, due date, amount, millage lines, and payment method. | Pay through official city treasury/payment resources before penalty applies. |
| Winter tax bill | Bill date, final city collection date, and any balance from earlier periods. | Confirm whether mortgage escrow pays this bill or whether you must pay directly. |
| Penalty period | Late fee, interest, penalty date, and payment acceptance rules. | Contact city treasury before assuming the same payment method still applies. |
| Delinquent / returned taxes | Whether unpaid taxes have moved to Washtenaw County. | Use the Washtenaw County Treasurer when taxes are returned delinquent. |
What to Do If Your Ann Arbor Property Tax Bill Looks Too High
A higher bill can come from millage changes, taxable value changes, ownership transfer uncapping, new construction, missing Principal Residence Exemption, special assessments, or delinquent penalties. Identify the reason before calling.
Check taxable value
Use City Assessing to review taxable value, assessed value, classification, and record details.
Check PRE / exemptions
Review Michigan property tax exemption and Principal Residence Exemption information through Michigan.gov.
Check special assessments
Special charges can make a bill higher even when taxable value looks normal.
1
Compare taxable value to last year
Taxable value changes often explain bill changes.
▾
Compare assessed value, taxable value, property class, and exemption fields from current and prior records using City Assessing resources.
2
Check whether ownership transfer uncapped taxable value
New buyers should not rely only on the seller’s old bill.
▾
If the property recently sold, taxable value may change under Michigan rules. Review state guidance at Michigan property tax resources and contact City Assessing for local record questions.

Separate payment questions from assessment questions
The payment office usually cannot change taxable value.
▾
Use city treasury resources for payment, balance, penalty, and receipt questions. Use City Assessing for taxable value, property classification, exemption, and assessment questions. Use Washtenaw County Treasurer for delinquent tax matters.

Ann Arbor Property Tax Tips That Prevent Wrong Payments and Bad Estimates
These tips are useful for homeowners, first-time buyers, landlords, escrow users, heirs, and anyone comparing Ann Arbor property taxes before a purchase.
Estimate from taxable value, not Zillow value
Market estimates do not calculate Michigan property taxes. Use taxable value and millage lines.
New buyers should expect possible uncapping
The seller’s old tax bill can be misleading if taxable value uncaps after transfer.
Confirm escrow before paying
If your lender pays taxes, verify whether the bill is already scheduled for payment before paying yourself.
Separate city and county tax roles
City handles current tax payment and assessing records; county may handle delinquent taxes.
Check PRE early
A missing Principal Residence Exemption can make a bill higher. Review city and Michigan guidance before deadlines.
Save proof after every payment
Keep confirmation number, amount, date, tax year, parcel, and payment method in case posting is delayed.
