Oakland County Property Tax Appeal, Michigan

Travis Bunn·Updated July 24, 2026

Oakland County is Michigan's second-most populous county with approximately 1.27 million residents across 62 cities, villages, and townships. Located in Metro Detroit's northern suburbs with the county seat in Pontiac and largest city Troy, Oakland County is one of the wealthiest counties in the United States. Property tax appeals are particularly important here given the county's median annual tax bill of $3,235, which is $835 higher than Michigan's state median and $835 above the national median of $2,400. The county's effective tax rate of 1.04-1.75% (depending on the source) ranks among the highest in Michigan, making accurate assessments critical for homeowners managing housing costs.

On the typical Oakland County home, valued near $301,920 at the county’s effective tax rate of 1.04%, an over-assessment of even 10% means you are overpaying year after year until you appeal it. Here is how to find out if yours qualifies.

2026 Appeal Deadline: March Board of Review - typically the Tuesday following the first Monday in March 2026, or March 9, 2026 for most municipalities; Commercial/industrial properties: May 31, 2026 for Michigan Tax Tribunal

This year's appeal window has passed in most of Michigan. Order now and we re-run your numbers free when the window reopens, so your evidence is ready the day your next notice lands.

Residential property owners must first appeal to the local March Board of Review, which convenes in March. Assessment notices are mailed in February. Commercial and industrial property owners can bypass the local Board of Review and appeal directly to the Michigan Tax Tribunal with a deadline of May 31, 2026. Missing the March deadline forfeits your right to appeal for that tax year.

How Oakland County Assesses Property

50%of market value

Assessed by: Oakland County Equalization Division and Local City/Township Assessors

Assessment cycle: annual

Notices typically mailed: February

In Oakland County, properties are assessed at 50% of their true cash (market) value, called the State Equalized Value (SEV). If your home's market value is $301,920 (the county median), your assessed value would be $150,960. At Oakland County's effective rate of 1.04%, this results in approximately $1,570 in annual taxes before exemptions. However, with the Principal Residence Exemption removing 18 mills, homeowners typically save $2,700 or more annually.

The Appeal Process

Appeals are heard by the Board of Review / Michigan Tax Tribunal. After filing your appeal, you'll either have an informal discussion with the assessor or attend a formal Board of Review hearing where you present your evidence. The Board will review your case, ask questions, and issue a decision that may reduce, maintain, or in rare cases increase your assessment.

Step 1: Review your Assessment Notice received in February and compare your assessed value (SEV) to recent comparable sales in your neighborhood to determine if your property is overassessed.

Step 2: Gather supporting evidence including recent comparable sales data (comps showing lower values), a professional appraisal, photographs documenting property condition issues, repair estimates for defects, and any other documentation supporting a lower market value.

Step 3: Contact your local assessor immediately after receiving your notice to discuss the valuation informally. For properties in municipalities served by Oakland County Equalization Division, call 248-858-0776. Many disputes are resolved at this stage without a formal hearing.

Step 4: If informal discussion doesn't resolve the issue, schedule an appointment for the March Board of Review, which typically meets the Tuesday following the first Monday in March. You must file your appeal before the Board of Review deadline - missing this window forfeits your appeal right for the year.

Step 5: Attend your scheduled Board of Review hearing (or submit a letter appeal if you're a non-resident or your municipality allows it) and present your evidence showing why your assessed value should be reduced. The Board will review your case and issue a decision.

Step 6: If the Board of Review denies your appeal or you're dissatisfied with their decision, you can appeal to the Michigan Tax Tribunal. Residential property owners must first go through the March Board of Review before appealing to the Tribunal. File your written petition with the Michigan Tax Tribunal by May 31, 2026.

Step 7: If still unsatisfied after the Michigan Tax Tribunal decision, you have the option to appeal the assessment in court as a final remedy.

Frequently Asked Questions

What is the deadline to appeal my property taxes in Oakland County for 2026?

For residential properties in Oakland County, you must first appeal to the March Board of Review, which typically meets the Tuesday following the first Monday in March - for 2026, this is March 9 in most municipalities. You should contact your local assessor immediately after receiving your assessment notice in February to schedule an appointment, as missing the March deadline means you forfeit your right to appeal for the entire tax year. Commercial and industrial property owners have a different option: they can bypass the local Board of Review entirely and appeal directly to the Michigan Tax Tribunal with a written petition that must be filed by May 31, 2026. Non-resident property owners can submit letter appeals to the March Board of Review if they cannot appear in person.

How do I file a property tax appeal in Oakland County online?

Oakland County property tax appeals typically cannot be filed completely online, unlike some other counties. While you can access property information through Oakland County's Property Gateway (https://www.oakgov.com/government/property-gateway) and the BS&A Online portal to research your assessment and view comparable properties, you must contact your local assessor directly to initiate an appeal. Call the Oakland County Equalization Division at 248-858-0776 (for municipalities they serve) or your local city/township assessor to discuss your property's valuation and schedule an appointment for the March Board of Review. Some municipalities may accept emailed documentation, but the initial appeal filing requires direct contact with the assessor's office rather than an online submission portal.

What is the Principal Residence Exemption worth in Oakland County?

The Principal Residence Exemption (PRE) is the most valuable property tax break available to Oakland County homeowners, exempting your primary residence from 18 mills of local school operating tax. On Oakland County's median home with a taxable value around $150,000, the PRE saves approximately $2,700 annually - that's $225 per month. For higher-value homes in areas like Birmingham or Bloomfield Hills with taxable values of $400,000, savings can exceed $7,200 per year. However, you must file Form 2368 with your local assessor to claim this exemption - it is not automatic. Many Oakland County homeowners mistakenly pay thousands in unnecessary taxes each year simply because they never filed for the PRE after purchasing their home. The application deadlines are June 1 for summer taxes and November 1 for winter taxes.

What happens at a Board of Review hearing in Oakland County?

At an Oakland County Board of Review hearing, you'll present your case to a panel of appointed board members explaining why your property assessment is too high. You should bring all supporting evidence including recent comparable sales showing similar homes sold for less than your assessed value, photographs of property defects or condition issues, repair estimates, and any professional appraisals. The hearing typically lasts 10-20 minutes, and the assessor may also present information defending the current assessment. The Board will ask questions, review your evidence, and then issue a decision either immediately or within a few days by mail. They can reduce your assessed value, keep it the same, or in rare cases increase it if evidence shows underassessment. If you disagree with the Board's decision, you have the right to appeal to the Michigan Tax Tribunal as a next step, but you must first go through the local Board of Review process.

How much can I save by appealing my property taxes in Oakland County?

Successful property tax appeals in Oakland County save homeowners an average of $1,485 per year according to industry data. However, actual savings vary significantly based on how much your property is overassessed and your home's value. If your assessment is reduced by $20,000 in market value (meaning $10,000 in SEV due to the 50% assessment ratio), you would save approximately $175-350 annually depending on your local millage rate. For properties that are substantially overassessed by $50,000-$100,000 in market value, savings can reach $1,000-$3,500 per year. Statistics show that approximately 25% of homes nationally are overassessed, paying an average of $1,346 too much annually. Given Oakland County's higher-than-average property values and tax rates, the potential savings from a successful appeal are substantial, particularly for homeowners in Troy, Southfield, or Farmington Hills where property values are consistently high.

What evidence do I need for an Oakland County property tax appeal?

To build a strong property tax appeal in Oakland County, you need comparable sales data showing that similar homes in your neighborhood sold for less than your assessed value within the past 6-12 months - focus on properties with similar square footage, age, condition, and features. A professional appraisal from a licensed appraiser can be very persuasive evidence, though it costs $300-500. Photograph any property defects, damage, or condition issues that reduce your home's value, such as foundation cracks, roof damage, outdated systems, or needed repairs. Obtain contractor estimates for major repairs to document deferred maintenance costs. You should also review your property record card (available through your assessor's office) for errors in square footage, number of rooms, lot size, or other characteristics that might inflate your assessment. The Oakland County Equalization Division recommends bringing all this documentation organized in a clear presentation to your Board of Review hearing, with the comparable sales being the most critical piece of evidence.

Do I need to appeal my Oakland County property taxes every year?

No, you do not automatically need to appeal every year, but you should review your assessment notice each February to determine if an appeal is warranted for that specific tax year. Your assessed value can increase each year due to market changes, property improvements, or reassessments, so what was accurate last year may be too high this year. Under Michigan's Proposal A, your taxable value can only increase by the rate of inflation (2.7% for 2026) or 5%, whichever is lower, unless you made significant improvements or ownership transferred. However, if you recently purchased your home, your taxable value uncaps and resets to the current assessed value, often causing a substantial tax increase that may warrant an appeal. Many Oakland County homeowners find it worthwhile to review comparable sales annually, especially in neighborhoods where home values are declining or stagnant, as assessors may not adjust values downward as quickly as the market changes. If you successfully appealed last year, you should still verify the new assessment is correct for the current year.

Can I appeal my Oakland County property taxes if I just bought the house?

Yes, you can definitely appeal your Oakland County property taxes even if you just purchased the home, and in fact recent buyers often have strong grounds for appeal. When you buy a property in Michigan, the taxable value uncaps and resets to the assessed value (50% of market value), which often causes a significant tax increase compared to what the previous owner paid. If you purchased your home for less than twice the assessed value on your tax notice, this indicates your assessment may be too high, since the assessed value should equal 50% of true market value. Your purchase price is compelling evidence of market value - if you paid $280,000 but your assessed value is $150,000 (implying a $300,000 market value), you have strong grounds for appeal. However, if you paid more than the assessed value suggests, the assessor could potentially use your purchase price to justify the current assessment or even increase it. New buyers in Oakland County should carefully review their first assessment notice and appeal if the numbers don't align with their actual purchase price and market conditions.
