How to Appeal Your Property Tax in Michigan: Step-by-Step Guide
Michigan property tax assessments are set by local assessors, but they’re not always accurate. Assessors estimate market values using mass appraisal methods that can miss individual property conditions, recent sales trends, or errors in property records. If your State Equalized Value (SEV) exceeds 50% of what your home would actually sell for, you’re being over-assessed — and you have a legal right to challenge it.
The appeal process in Michigan is structured, time-sensitive, and available to every property owner. The March Board of Review is your first opportunity, and if that doesn’t resolve the issue, the Michigan Tax Tribunal provides a second level of appeal. Here’s exactly how to do it, step by step, with deadlines you cannot miss.
When Should You Appeal?
You should consider appealing your Michigan property tax assessment if any of the following apply:
- Your SEV exceeds 50% of your home’s fair market value. If comparable homes in your neighborhood are selling for $300,000, your SEV should be approximately $150,000. If it’s $170,000, you’re being over-assessed by about $20,000.
- Your property record contains errors. Wrong square footage, extra bedrooms or bathrooms counted, a finished basement that isn’t actually finished, or an incorrect lot size can all inflate your assessment.
- Your home has condition issues the assessor doesn’t know about. Foundation problems, outdated systems, environmental contamination, or structural damage can reduce market value below what the assessor’s model suggests.
- Comparable sales in your area have declined. If the housing market in your specific neighborhood has softened, your assessment may not reflect current reality.
| Assessment Check | What to Compare | Action If Over-Assessed |
|---|---|---|
| SEV vs. 50% of market value | SEV on assessment notice vs. recent comparable sales ÷ 2 | Appeal to Board of Review |
| Property record accuracy | Square footage, bedrooms, baths, lot size on assessment card | Request correction from assessor |
| Taxable value cap compliance | Prior year TV × CPI increase cap vs. current TV | Verify Proposal A cap applied correctly |
| PRE status | Is 18-mill exemption reflected on tax bill? | File or re-file Form 2368 |
Step 1: Review Your Assessment Notice (February)
Assessment notices are mailed in February. The notice shows your property’s:
- Assessed Value: Same as SEV — should equal 50% of market value
- Taxable Value: The capped value used for your tax bill (may be lower than SEV for long-term owners)
- Tentative New SEV: The assessor’s updated estimate for the coming year
- Classification: Residential, commercial, agricultural, etc.
Compare the SEV to recent sales of similar homes in your immediate area. Focus on homes that sold within the past 6–12 months, similar in size, age, condition, and location. If three comparable homes sold for $280,000, $290,000, and $300,000, the average market value is about $290,000, and your SEV should be approximately $145,000. If your assessment notice shows $165,000, you have a strong case for appeal.
Step 2: Gather Evidence
The Board of Review evaluates evidence, not opinions. Prepare the following:
Comparable Sales
Find 3–5 recent sales of similar homes within a half-mile radius if possible. Include:
- Sale price and date
- Square footage, bedrooms, bathrooms
- Year built and lot size
- Condition adjustments (if your home is in worse condition than the comp)
Your real estate agent can pull MLS data. County register of deeds websites also show recorded sale prices. You can also check Zillow or Realtor.com for recently sold data, though MLS records are more complete.
Property Record Card Review
Request your property record card from the assessor’s office (available in person, by mail, or online in some municipalities). Check every detail:
- Is the square footage correct? (Measure if uncertain)
- Are the bedroom and bathroom counts right?
- Is the basement listed as finished when it’s actually unfinished?
- Is the garage measured correctly?
- Is the lot size accurate?
- Is the building quality grade appropriate?
Condition Documentation
If your home has issues that reduce its value below what comparable sales suggest, document them:
- Photos of foundation damage, water infiltration, or structural problems
- Contractor estimates for necessary repairs
- Inspection reports identifying deficiencies
- Environmental reports (lead paint, asbestos, mold)
Step 3: Attend the March Board of Review
Every Michigan municipality holds a Board of Review in March. This is your primary appeal venue and the only one available without filing fees or formal legal proceedings.
Key Deadlines
| Event | Typical Date | Action Required |
|---|---|---|
| Assessment notices mailed | Late February | Review your notice immediately |
| Board of Review first meeting | Second Monday in March | Organizational meeting (no hearings) |
| Board of Review hearings | Second and third week of March | Attend your hearing or submit written protest |
| Board of Review final session | Last business day before April board meeting | Deadline for protest submission |
How to Present Your Case
- Sign up for a hearing slot. Contact your local assessor’s office or municipal clerk to schedule. Walk-ins are sometimes accepted but appointments are better.
- Bring your evidence organized. Print copies of comparable sales, your property record card, photos, and any supporting documents. Bring enough copies for each board member (typically 3).
- State your position clearly. Example: “My current SEV is $165,000. Based on comparable sales in my neighborhood averaging $290,000, my SEV should be approximately $145,000. I’m requesting a reduction of $20,000.”
- Present comparable sales first. This is your strongest evidence. Show the board that similar homes are selling for less than 2x your SEV.
- Note any property record errors. If the card shows incorrect data, point it out specifically.
- Be polite and factual. The board members are usually local residents, not real estate professionals. Clear, organized presentations work better than emotional arguments.
Written Protest Option
If you can’t attend in person, you can submit a written protest letter. Michigan law requires Boards of Review to consider written protests submitted by the filing deadline. Include all the same evidence you’d present in person, a clear statement of the relief you’re requesting, and your contact information.

Step 4: Receive the Board’s Decision
The Board of Review will mail its decision, typically within 2–4 weeks of the hearing. The board can:
- Grant your full request — your SEV is reduced to the amount you requested
- Grant a partial reduction — the board agrees your assessment is high but not by as much as you claimed
- Deny your appeal — the board upholds the assessor’s value
If the board denies your appeal or grants insufficient relief, you have the right to escalate to the Michigan Tax Tribunal.
Step 5: Michigan Tax Tribunal (If Needed)
The Michigan Tax Tribunal (MTT) is the next level of appeal. Key details:
- Filing deadline: July 31 of the tax year (you must have first appealed to the Board of Review)
- Filing fee: $25–$250 depending on the property classification and dispute amount
- Small Claims Division: For residential properties with disputes under $100,000. Simpler process, no formal rules of evidence.
- Entire Tribunal: For larger disputes. More formal, legal representation recommended.
- Timeline: MTT cases typically take 12–18 months to resolve
Most residential appeals are heard in the Small Claims Division, where homeowners can represent themselves without an attorney. The process involves filing a petition, exchanging evidence with the assessor’s office, and attending a hearing (often conducted via video conference). The tribunal considers the same types of evidence — comparable sales, property condition, record errors — used at the Board of Review level.
Common Mistakes to Avoid
- Missing deadlines. The March Board of Review window is short. Miss it, and you wait until next year unless you file with the MTT by July 31.
- Using Zillow estimates as evidence. Boards of Review and the MTT want actual sales data, not algorithm-generated estimates. Use recorded transactions from the MLS or county records.
- Confusing taxable value with SEV. You appeal the SEV (assessed value). The taxable value is a separate calculation governed by Proposal A caps. A Board of Review cannot reduce your taxable value below the Proposal A formula.
- Not verifying your property record. Simple data errors (wrong square footage, extra bathroom counted) are common and can inflate your assessment. These are the easiest wins in the appeal process.
- Being adversarial. Board members are community volunteers. Presenting facts calmly and respectfully gets better results than complaining about taxes being too high in general.
Use our property tax estimator to understand how assessment reductions translate to annual tax savings. And the mortgage payment estimator shows how lower taxes reduce your total monthly housing cost.
How Much Can You Save?
| Assessment Reduction | Annual Tax Savings (at 45 mills) | Annual Tax Savings (at 68 mills) |
|---|---|---|
| $10,000 SEV reduction | $450 | $680 |
| $20,000 SEV reduction | $900 | $1,360 |
| $30,000 SEV reduction | $1,350 | $2,040 |
| $50,000 SEV reduction | $2,250 | $3,400 |
A $20,000 SEV reduction saves $900–$1,360 per year depending on your local millage rate. Over 10 years (assuming the cap keeps your taxable value growth modest), that’s $9,000–$13,600 in savings from a few hours of preparation and a Board of Review appearance.

Professional Help: When to Hire a Tax Consultant
Most residential property tax appeals are straightforward enough to handle yourself. But certain situations benefit from professional assistance:
| Situation | DIY or Hire? | Expected Cost | Likely Outcome |
|---|---|---|---|
| Simple over-assessment (clear comparable sales) | DIY | $0 | 70–80% success rate at Board of Review |
| Property record errors (wrong sq ft, features) | DIY | $0 | 90%+ success — errors are factual corrections |
| Complex property (unique, high-value, commercial) | Hire | $1,000–$5,000 | Professional appraisal carries more weight |
| Michigan Tax Tribunal appeal | Consider hiring | $1,500–$5,000 | More formal process, attorney adds credibility |
| New construction assessment dispute | Hire | $500–$2,000 | Assessors often over-value new builds initially |
Some property tax consultants in Michigan work on contingency — they take a percentage (typically 25–40%) of the first year’s tax savings. This means no upfront cost, but the savings split reduces your benefit. For large potential reductions ($5,000+ in annual savings), the contingency model makes sense. For smaller disputes, the DIY approach at the Board of Review is usually sufficient.
If you hire an appraiser to support your appeal, make sure they’re Michigan-certified and experienced with assessment appeals specifically. A standard mortgage appraisal ($400–$600) focuses on lending value, while an appeal appraisal ($300–$500) focuses specifically on demonstrating that the assessed value exceeds market value. Use our amortization calculator for detailed numbers. Ask the appraiser if they’ve testified at Board of Review hearings or before the MTT — experience in these settings matters.

Frequently Asked Questions
When can I appeal my Michigan property tax?
The primary appeal window is the March Board of Review, held during the second and third weeks of March. You must attend (or submit a written protest) during this window. If unsatisfied, you can escalate to the Michigan Tax Tribunal by filing by July 31. Assessment notices arrive in February, giving you a few weeks to prepare.
How much does it cost to appeal?
The March Board of Review appeal is free. Michigan Tax Tribunal Small Claims Division filing fees are $25–$250 depending on the dispute amount. If you hire a property tax attorney or consultant, expect fees of $500–$2,000 for Board of Review representation and $1,000–$5,000 for MTT cases.
What evidence works best for a property tax appeal?
Comparable sales are the strongest evidence — recent transactions of similar homes that sold for less than 2x your SEV. Property record errors (incorrect square footage, wrong bedroom count) are the easiest to prove. Documented condition issues (foundation damage, outdated systems) with contractor estimates also carry weight. Use our find home professionals for detailed numbers. Board members want data, not opinions or emotions.
Can I appeal if I just bought my home?
Yes, but it’s harder. Your recent purchase price is strong evidence of market value, which means your SEV should be approximately half of what you paid. If your assessment already reflects roughly 50% of your purchase price, there’s little to appeal. However, if the assessor raised the SEV above 50% of your price, or if the property has issues that weren’t reflected in the price, you have grounds. Use our calculate your closing costs to review your total purchase costs.
Will appealing increase my assessment?
No. Michigan law specifically prohibits Boards of Review from increasing your assessment as a result of your appeal. The worst outcome is the board upholds the existing assessment unchanged. You cannot be penalized for appealing, and the board can only lower or maintain — never raise — your value during the appeal process.
