Washtenaw County property tax appeals
Appeal Season is a property tax appeal co-pilot. We are expanding county by county to high-tax areas like Washtenaw County. We are not there yet, so we cannot check a Michigan assessment today. Leave your email and we will tell you the day we cover Washtenaw County, and nothing else.
Michigan taxes a capped taxable value that can only rise by inflation or 5 percent until you sell, so an appeal often will not lower your bill. You protest at your local March board of review. It is most likely to help right after a purchase or if your assessed value is clearly above half of market.
- You just bought, so the cap reset to market and the value looks too high.
- Your assessed value is clearly above 50 percent of what the home would sell for.
- The record has wrong facts about your home.
- Your taxable value is capped below market, so a lower assessed value would not reach your bill.
- Your bill went up only by the inflation cap. That is the law working as intended, not an over-assessment.
Read the full explanation
In Michigan, your local assessor sets an assessed value at about 50 percent of market value, but your tax is based on a separate taxable value that is capped. Under Proposal A, your taxable value can only rise by inflation or 5 percent, whichever is less, until you sell the home, so an appeal often will not lower your bill unless your assessed value drops below that capped taxable value. You protest at your local March board of review first, then can appeal to the Michigan Tax Tribunal. An appeal is most likely to help right after you buy, when the cap resets, or if your assessed value is clearly above half of market. This is general information, not tax advice.

- Filing window:
- You protest your value at your local March board of review, then may appeal to the Michigan Tax Tribunal. But Michigan caps how much your taxable value can rise each year (inflation or 5 percent, whichever is less) until you sell, so unless your assessed value falls below that capped taxable value, a protest often will not lower your bill. Check your city or township for its exact March board dates.
