Property Tax in Jefferson County, Kentucky
The median real estate tax bill in Jefferson County, Kentucky is $2,023 per year, and the median home is worth $237,200. Both figures are the US Census Bureau's survey medians for owner-occupied households (US Census Bureau, American Community Survey (ACS) 5-year estimates, 2023).
What the Jefferson County numbers mean
A median is the middle household: half of owner-occupied households in Jefferson County pay more than $2,023, and half pay less. Your own bill is set by your home's assessed value, the exemptions you qualify for, and the local taxing districts your property sits in — so individual bills vary widely around the median.
Dividing the median tax by the median home value gives a derived effective rate of 0.85% for Jefferson County. It is an estimate built from two survey medians, not the county's official rate, but it is a fair way to compare the local tax burden with other counties where home values are very different.

How the tax is worked out
The bill is built in stages. First the assessor puts a market value on the property. Exemptions — a homestead exemption above all — then reduce the taxable amount. Finally the combined local rate is applied. To see the scale: at the county's derived rate of 0.85%, each $100,000 of value corresponds to about $853 of tax a year, and a $400,000 home to roughly $3,412. Real bills use the official assessment and district rates, not this derived figure, so treat the example as a sense of scale only.
Checking your assessment in Jefferson County
If your bill looks wrong, work through these steps:
1. Get your property record card from the assessor and check the basics — living area, lot size, bedrooms, condition, and any exemptions you should have.
2. Compare your assessed value with recent sale prices of similar homes in Jefferson County.
3. Talk to the assessor's office informally first; clear errors are often fixed without a hearing.
4. If needed, file a formal appeal with the local review board before the deadline on your assessment notice, with your evidence attached.
5. Keep paying the bill as issued while the appeal runs, unless your notice says otherwise — unpaid taxes accrue penalties regardless of an appeal.
