How property tax works in Wayne County
Effective rate
1.98% of market value · median annual bill $8,910
How homes are assessed
Michigan taxes 'taxable value' capped at 50% of market value (State Equalized Value); taxable value growth is capped at inflation or 5%/yr until the property transfers.
Homestead exemption
Principal Residence Exemption (PRE) exempts the home from up to 18 mills of school operating tax — a rate reduction rather than a dollar exemption.
Appealing your assessment
March Board of Review in the local township/city; further appeal to the Michigan Tax Tribunal by the end of July for residential.
When bills are due
Summer bills due September 14; winter bills due February 14 (local variation exists).
Local note
Detroit millage is a major outlier vs suburbs — worth a callout box on the county page.
