Michigan Property Tax Appeals: Don’t Miss the March Deadline

If your property tax bill feels higher than it should, March is your window to challenge it.
Every year, Michigan homeowners get a short opportunity—usually just a few weeks—to appeal their property’s assessed value through the local Board of Review. Miss it, and you’re often stuck paying that higher tax bill for another year (or more).
The good news? A successful appeal doesn’t just save money this year—it can lower your tax baseline for years to come.
Here’s how Michigan property tax appeals work, who should consider one, and what to do right now.
How Michigan Property Taxes Actually Work
Your property taxes are based on value—not what you paid, and not what you can afford.
Here’s the simplified breakdown:
SEV (State Equalized Value): Intended to represent 50% of your home’s market value
Taxable Value: The number your taxes are actually calculated on
Millage Rate: The local tax rate (schools, libraries, roads, etc.)
Michigan has a taxable value cap, meaning increases are usually limited each year—until you buy or sell a home. After a sale, that cap is removed, which is why many new homeowners see a sharp tax increase.
If your home is over-assessed, you’ll keep overpaying every year unless you appeal.
When a Property Tax Appeal Makes Sense
You don’t need a dramatic mistake to justify an appeal. These are common, valid reasons Michigan homeowners appeal successfully:
Your assessment jumped unexpectedly while nearby homes didn’t
Your home’s condition isn’t accurately reflected (outdated systems, deferred maintenance, foundation issues)
Recent comparable sales are lower than your assessed value
You recently purchased the home for less than the assessment
Your taxes uncapped after purchase and the value feels inflated
If any of these apply, it’s worth taking a closer look.
Michigan Board of Review: Why March Matters
Most Michigan communities hold Board of Review in March, and the filing window is short—often 2–3 weeks.
If you miss it:
You usually must wait until next year, or
File with the Michigan Tax Tribunal (more complex and formal)
How to find your exact deadline:
Check your property tax bill
Visit your city or township assessor’s website
Call the assessor’s office directly
Tip: Appointments fill quickly—waiting until the last minute can cost you the chance to appeal.
How to Prepare a Strong Appeal
The strongest appeals are fact-based and well-documented, not emotional.
What to gather:
3–5 comparable home sales (same neighborhood, similar size/age, sold in last 6–12 months)
Photos of condition issues (roof, basement, systems, foundation, outdated finishes)
Your property card from the assessor’s office (errors are common)
Common assessment errors:
Incorrect square footage
Wrong number of bedrooms or bathrooms
Finished basement listed when unfinished
Missing property defects
Incorrect lot size
Even small errors can add up to hundreds of dollars per year.
What the Appeal Process Looks Like
Level 1: Informal ReviewOften your best chance. You meet with the assessor, present your evidence, and many corrections happen here.
Level 2: Board of ReviewA small panel reviews your case. It’s still relatively informal—clear documentation matters most.
Level 3: Michigan Tax TribunalA formal legal process. This only makes sense when potential savings justify the cost and effort.
When an Appeal Probably Isn’t Worth It
Appeals don’t fix everything. You may want to skip it if:
Your assessment is reasonable and taxes are high due to millage, not value
Potential savings are minimal (under $100–$200 per year)
Comparable sales support your current value
Appeal strategically—not just out of frustration.

FAQs: Michigan Property Tax Appeals
Do I have to appeal every year?
No—but if your value stays inflated, appealing again with updated data can help.
Will appealing raise my taxes?
No. An appeal cannot increase your assessment.
Can a successful appeal help future years?
Yes. Lowering your assessed value creates a lower starting point going forward.
