How Property Tax Works

Kent County, Michigan operates under the state's property tax system to fund essential local services including public schools, municipal services, county operations, and special districts. Property taxes are the primary revenue source for K-12 education, local government services, libraries, and infrastructure maintenance throughout the county's 30 townships and cities.

The effective property tax rate in Kent County typically ranges from approximately 25-45 mills (2.5% to 4.5%) of taxable value, depending on your specific location and the special taxing districts that serve your property. Actual rates vary significantly across the county due to different combinations of school districts, municipal boundaries, library districts, transit authorities, and other special assessments. Properties are assessed at 50% of true cash value under Michigan law, with taxes calculated on the lower of assessed value or capped value (taxable value).

Section 4

Supplemental Tax Bills

Supplemental taxes in Kent County are additional property tax bills issued when property ownership changes or new construction is completed after the annual assessment date (typically December 31st). These taxes represent the difference between what the previous owner paid and what should be paid based on current assessed value.

Supplemental taxes are calculated by determining the new taxable value, applying current tax rates, and prorating for the portion of the tax year remaining. For example, if you purchase a $400,000 home in June that was previously assessed at $250,000, you would receive a supplemental bill for the increased tax amount covering July through December. The calculation uses the same millage rates as regular property taxes but only applies to the value difference for the remaining months of the tax year.

Escrow & Property Taxes

Most mortgage lenders in Kent County require property tax escrow accounts for loans with less than 20% down payment. Lenders collect 1/12th of your estimated annual property tax bill each month along with your mortgage payment. Kent County property taxes are typically collected in two installments: summer taxes (due July 1st) and winter taxes (due December 1st), though some municipalities may have different schedules.

Your lender will pay these bills directly to Kent County Treasurer or the appropriate collecting unit on your behalf. After each tax year, lenders perform an escrow analysis to ensure adequate funds are collected, which may result in escrow payment adjustments. You can verify tax payments through Kent County's online property search system or by contacting your loan servicer for escrow account statements. If you pay taxes directly, remember that failure to pay by the due dates results in interest charges and potential tax foreclosure proceedings.
