How to Appeal Your Michigan Property Tax Assessment: Step-by-Step Board of Review Guide

If you think your Michigan property tax assessment is too high, you can appeal it. Many Michigan homeowners win meaningful tax reductions through the appeal process every year, but the deadlines are strict and the process has specific requirements. Miss the March Board of Review window and you wait an entire year. This guide walks through exactly how to appeal your Michigan property tax assessment, what evidence wins, and the escalation path to the Michigan Tax Tribunal if the local board denies your appeal.

When to Appeal

You should consider appealing if your assessed value (which should equal 50 percent of market value) is meaningfully higher than what your home would actually sell for. Specifically: the assessed value implies a market value 10 percent or more above what comparable homes nearby have actually sold for, the assessor has incorrect data on your home (square footage, bedrooms, bathrooms, lot size), the home has condition issues the assessor did not account for (foundation problems, fire damage, deferred maintenance), or your assessment increased substantially from last year while comparable homes did not.

When You Cannot Appeal

You cannot appeal because you cannot afford the tax. Property tax is based on property value, not owner income. If your tax bill is unaffordable, look at the Poverty Tax Exemption (for low-income homeowners), the Pay As You Stay program, or senior and disability exemptions instead. The Board of Review can only adjust the value, not the bill itself.

The Two Annual Windows

March Board of Review (the main appeal window)

The Board of Review meets in March each year, typically the second or third week. This is the main window to appeal your annual assessment. You receive your annual assessment notice in late February. You then have a few weeks to file an appeal and present your case.

July and December Board of Review (limited)

The July and December Boards of Review handle very narrow issues: clerical errors, mutual mistakes of fact, qualified errors, and Principal Residence Exemption disputes. You cannot use these to appeal a value you missed in March.

Step-by-Step: How to File the Appeal

Step 1: Get Your Assessment Notice

In late February you receive a Notice of Assessment, Taxable Valuation, and Property Classification from your local assessor. This shows your prior year and current year Assessed Value, State Equalized Value, and Taxable Value. Read it carefully. The numbers and any change between years are the basis of your appeal.

Step 2: Verify the Property Record

Visit your local assessor office (or check online if your municipality has online records) and pull the property record card for your home. Verify everything: square footage, number of bedrooms and bathrooms, lot size, year built, basement type, garage size, deck and other improvements. Errors in this data are some of the easiest wins. The assessor was probably valuing a home larger than yours.

Step 3: Pull Comparable Sales

The single most powerful evidence is comparable sales of similar homes nearby that sold in the past 12 to 24 months. Use Zillow, Redfin, Realtor.com, or the MLS through your real estate agent if you have one. Pull 3 to 6 comps that are similar in square footage, age, condition, lot size, and neighborhood. Calculate the average sale price per square foot. Compare to your assessment.

Step 4: Get a Professional Appraisal (Optional but Powerful)

A formal appraisal from a Michigan-licensed appraiser ($400 to $600) carries more weight than do-it-yourself comps. If your potential tax savings are substantial (over $500 per year for several years), the appraisal pays for itself.

Step 5: File Form L-4035 (Petition to Board of Review)

Get the Petition to Board of Review form (Form L-4035) from your local assessor office or municipal website. Fill it out completely. List the property address, parcel number, current assessed value, your proposed assessed value, and the basis for your appeal. Submit by the deadline (varies by municipality, typically the day before the Board meets).

Step 6: Schedule and Attend Your Hearing

You will get a hearing time, typically 10 to 15 minutes. Bring your evidence: comp printouts, the property record card showing errors, the appraisal if you got one, and any photos showing condition issues. Be respectful and concise. State the value you believe is correct and the evidence supporting it.

Step 7: Receive the Decision

The Board of Review issues written decisions within a few weeks. If they grant a reduction, your assessment is adjusted and your tax bill goes down accordingly. If they deny or partially grant, you have the option to escalate.

Escalating to the Michigan Tax Tribunal

If the local Board of Review denies your appeal or grants less of a reduction than you believe is justified, you can appeal to the Michigan Tax Tribunal. There are two divisions:

Small Claims Division

For residential property and most appeals under $100,000 in dispute. Filing fee is around $135. The process is more formal than the Board of Review but still accessible to homeowners without an attorney. The deadline to file is July 31 of the year following the Board of Review denial.

Entire Tribunal

For larger commercial and industrial appeals. Requires more formal procedure, typically with attorney representation.

What Evidence Actually Wins

Boards of Review and the Tax Tribunal weigh evidence in roughly this order: (1) recent professional appraisal of YOUR property, (2) recent sales of comparable homes in your specific neighborhood, (3) documented errors in the assessor data on your property, (4) documented condition issues with photos and contractor estimates, (5) recent sale of YOUR property below assessed value, (6) market trend data showing the area is declining.

What does NOT win: emotional appeals, financial hardship arguments, comparisons to assessments of neighbors (rather than sales), or generic complaints about high taxes.

Realistic Expectations

Most successful appeals reduce assessed value by 5 to 15 percent. Larger reductions require strong evidence (significant assessor errors, major condition issues, or clear market changes). On a home assessed at $200,000 (market value $400,000), a 10 percent reduction lowers the bill by roughly $700 per year if your millage is around 35 mills. Compounded over 5 to 10 years, this is real money.

Common Appeal Mistakes

Missing the March Board of Review window
Coming with no evidence (just complaints)
Comparing to neighbors assessments instead of actual recent sales
Not verifying the property record card
Arguing about taxes rather than value
Bringing comp sales from a different neighborhood
Using comp sales more than 24 months old
Not photographing condition issues
Failing to submit the formal Petition before the deadline
Skipping the Tax Tribunal escalation when the Board ruling is wrong

When the Tax Bill Is Still Unaffordable

If the appeal does not bring your bill down to an affordable level, you may need to consider other paths. Senior, disability, and Poverty Tax Exemptions can provide significant relief. Payment plans through the county treasurer can spread out the bill. And if the home is no longer sustainable, selling for cash is often a faster way to preserve equity than letting the bill go unpaid for three years until tax foreclosure.

Get a Cash Offer If Selling Makes More Sense

If you are appealing because you cannot afford to stay in the home, call (810) 547-1135 for a no-obligation cash offer from Offer Now Michigan. We close in seven to 14 days and pay off any back taxes at closing.
