Assessment guide
How to appeal your Michigan assessment
If your SEV, or State Equalized Value, looks too high, you may be able to challenge it. The process is local and time-sensitive, so start as soon as the assessment notice arrives.
Read the assessment notice
Look for Assessed Value, SEV, and Taxable Value. The number to challenge is usually SEV or Assessed Value. Taxable Value may still be capped by Proposal A unless the property recently transferred.
Gather simple proof
Find comparable sales, photos of condition issues, incorrect square footage, or other facts that show the value is too high. The best evidence is specific and local.
Board of Review
Many residential appeals start with the local March Board of Review. This is a local board that hears property assessment protests each March. Deadlines are short. Check the notice and your city or township website for the exact dates, meeting rules, and whether written protests are accepted.
For many residential value appeals, protesting at the March Board of Review protects your right to keep going to the Michigan Tax Tribunal. That next deadline is usually later in the year, but do not rely on memory. Use your local notice and the current state appeal table.
If a high assessment changes your buying decision, speak with a Michigan property tax attorney or CPA. This site can explain the math, but it is not legal or tax advice.
