How Property Tax Works

Oldham County, Kentucky operates on an assessment-based property tax system that funds essential local services including schools, fire protection, libraries, and county operations. Property owners pay taxes based on their property's assessed value multiplied by the combined tax rates from various taxing districts. The county assesses real property at 100% of fair cash value as determined by the Property Valuation Administrator (PVA).

The effective tax rate in Oldham County varies significantly by location within the county due to different combinations of special taxing districts, including school districts, fire districts, and municipal services. Property owners should expect their actual tax rate to differ based on their specific location and the services provided in their area. The county portion of the tax rate for 2025 is $0.183 per $100 of assessed value, but additional district taxes will apply depending on your property's location.

Supplemental Tax Bills

Supplemental taxes in Oldham County are additional property tax bills issued when there are changes in property ownership, new construction completion, or significant property improvements that increase assessed value during the tax year. These supplemental bills are prorated based on the number of months remaining in the tax year after the change occurs.

For example, if you purchase a newly constructed home that was completed in January but the previous assessment didn't reflect the completed structure, you may receive a supplemental tax bill for the difference between the land-only assessment and the full property assessment. The supplemental tax would be calculated as: (New Assessed Value - Previous Assessed Value) × Tax Rate × Months Remaining ÷ 12. If the difference was $100,000 in assessed value and you had 8 months remaining in the tax year with a 1.0% effective rate, your supplemental tax would be approximately $667.

Escrow & Property Taxes

Most mortgage lenders in Oldham County collect property taxes through escrow accounts, spreading the annual tax burden across 12 monthly payments included in your mortgage payment. Lenders typically collect 1/12th of your estimated annual property tax each month, plus an additional cushion as allowed by federal law.

Property taxes in Oldham County are due May 15th annually, and lenders usually pay these taxes on your behalf from your escrow account before the due date. Your lender will provide an annual escrow analysis showing how your tax payments were applied and any adjustments needed for the following year. If your property taxes increase due to reassessment or rate changes, your monthly escrow payment may be adjusted accordingly. Property owners should verify that their lender has paid taxes on time and maintain communication about any supplemental tax bills that may not be automatically included in escrow calculations.
