Assessed value, SEV, and taxable value
A home’s asking price, market value, and taxable value are not interchangeable. Michigan assessment records commonly show assessed value, state equalized value (SEV), and taxable value. The taxable value is the figure used with millage rates to calculate ad valorem property tax; it may be lower than assessed value because annual increases are limited until a transfer of ownership or another statutory event changes the calculation.
After a qualifying transfer, taxable value generally becomes uncapped for the following tax year and is then subject to the applicable cap in later years. That is why a seller’s current bill can materially understate a buyer’s future tax bill. The exact outcome depends on the property record, exemptions, transfer, additions, millages, and timing.
What buyers should review
- Find the parcel record and confirm the taxing jurisdiction, assessed value, SEV, taxable value, principal-residence exemption status, and special assessments.
- Read the most recent Notice of Assessment and the current summer and winter tax bills instead of relying only on a listing field.
- Use current millage information and a reasonable post-transfer taxable-value assumption to model a range for the next full tax year.
- Ask the local assessor how the record treats additions, losses, exemptions, and the transfer. The assessor administers the official value; a calculator does not.
- If an appeal may be considered, confirm the current local Board of Review process and deadline; do not treat an appeal as a guaranteed reduction.
Compare the assessor’s property card
Review the assessor’s property card for building area, bedrooms, bathrooms, lot information, class, and improvements. A mismatch does not by itself prove the listing or assessment is wrong, but it is a question to resolve. Recent construction may also connect back to the permit history.
