How Property Tax Works

Boone County, Kentucky operates on a property tax system that funds essential local services including schools, libraries, health services, and county operations. Property taxes are the primary revenue source for the Boone County School District, county government, library services, health department operations, and extension services. The effective tax rate varies significantly by location within the county due to different combinations of special taxing districts and school district boundaries.

Property owners in Boone County can expect total tax rates ranging from approximately 0.80% to 0.85% of assessed value, depending on their specific taxing district. The largest component is typically the school district tax, followed by county government and state taxes. Rates vary based on whether your property falls within the Boone County School District or Kenton County School District boundaries, and which special service districts apply to your location.

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.
Section 4

Supplemental Tax Bills

Supplemental taxes in Boone County are additional property tax bills issued when there are mid-year changes to property ownership, value, or classification that weren't captured in the regular annual assessment. Common triggers include new construction completion, property transfers that reveal unreported improvements, successful appeals that increase assessed value, or changes in property use classification.

Supplemental taxes are calculated by applying the current year's tax rate to the difference between the new assessed value and the original assessed value, prorated for the portion of the tax year remaining. For example, if new construction adds $50,000 in assessed value and is completed in January, the supplemental tax would be calculated on the full $50,000 for the entire tax year. If completed in July, it would be prorated for approximately half the year.

Escrow & Property Taxes

Most mortgage lenders in Boone County collect property taxes through monthly escrow payments as part of your mortgage payment. Lenders typically collect 1/12th of your annual tax bill each month, plus an additional cushion amount (usually 2 months) to ensure adequate funds are available when taxes are due. Property tax bills are mailed on May 1st each year, with payment due dates of June 2nd and September 2nd.

Your lender will pay the taxes directly to Boone County on your behalf using funds from your escrow account. Each year, lenders must provide an escrow analysis showing how your tax payments compare to actual tax bills, and adjust your monthly payment accordingly. Property owners should verify that their lender has paid taxes on time, as the property owner remains ultimately responsible for tax payments even when using escrow services.
