Change of Assessment Notice

  • Notices are mailed 14 days prior to the first day of the March Board of Review per Michigan Complied Law (MCL)211.24c (4), typically the end of February each year.  

The following is a brief explanation of assessment terms contained in your property assessment notice.

ASSESSED VALUE: The State of Michigan requires that a property's assessed value is determined as 50% of the true cash value (fair market value). Generally, the assessed value is the same as the State Equalized Value (S.E.V.) unless an equalization factor has been applied by the County and/or State.

TAXABLE VALUE: The value used to calculate your property tax bill, it is not the same as the property's true cash value. A property's capped taxable value can only increase annually by the rate of inflation (CPI) or 5%, whichever is less, unless there are any physical changes to the property (physical improvement or removal, omitted property) or the property's ownership was transferred during the previous year, and can never be more than the property's assessed value.  2020 Inflation Rate is 1.9%.

TRANSFER OF OWNERSHIP: When there is a transfer of ownership on a property, the property's taxable value becomes uncapped and the taxable value will equal to the assessed value (SEV) for the year following the transfer.  However, certain types of transfers are exempt from uncapping.

PROPERTY CLASSIFICATION: The General Property Tax Law provides that all property be classified into certain classifications for the purpose of maintaining uniformity of assessed values.  Real property can be classified as residential improved or residential vacant, commercial improved or commercial vacant, industrial improved or industrial vacant, etc.
