Kentucky offers homeowners a very friendly property tax environment with a statewide effective rate of just 0.74%. The state strictly controls local property tax revenue growth through House Bill 44, forcing local governments to lower rates when property values surge (est., Tax Foundation 2026).
Kentucky maintains an intricate balance between state oversight and local control when it comes to property taxes. The state actively forces local governments to lower their millage rates when real estate markets boom, ensuring tax bills don’t rapidly inflate alongside home values.
100% Assessment and Fair Cash Value
In Kentucky, your property is assessed at 100% of its fair cash value. Property Valuation Administrators (PVAs) in each county are required to continually update valuations based on market sales data, and must physically inspect every parcel at least once every four years.
Unlike some states with fractional assessments, if your home could sell for $250,000 on the open market, your taxable value is $250,000.
Kentucky statewide effective rate. On a $250,000 home, expect approximately $1,850 per year at the statewide average. (est., Tax Foundation 2026).
| Home Value | Annual Tax (est.) | Monthly Payment | vs. U.S. Average |
|---|---|---|---|
| $150,000 | $1,110 | $92 | -$240 below avg. |
| $250,000 | $1,850 | $154 | -$400 below avg. |
| $400,000 | $2,960 | $246 | -$640 below avg. |
| $600,000 | $4,440 | $370 | -$960 below avg. |
| $800,000 | $5,920 | $493 | -$1,280 below avg. |

The House Bill 44 Cap (Revenue Growth Limits)
Kentucky does not cap the value of your home, but it does cap local government revenue via a 1979 law known as House Bill 44. The rule works like this:
- A local taxing district can only increase its total property tax revenue from existing property by up to 4% over the previous year.
- If property values spike by 10% across the county, the local government is forced to lower its tax rate to ensure revenue growth doesn’t exceed 4%. (Known as the “compensating rate”).
- If a local district attempts to set a rate that generates more than 4% revenue growth, the portion exceeding 4% is subject to a voter recall petition.
The Homestead Exemption ($49,100 for 2025)
Kentucky offers a robust Homestead Exemption strictly for residents who are 65 or older or classified as totally disabled. The state Constitution mandates that the exemption amount be adjusted every two years to account for inflation.
For the 2023-2024 tax years, the exemption reduced a qualified homeowner’s assessed value by $46,350. For the 2025-2026 tax years, this exemption has increased to $49,100.

Disclaimer and Methodology
This calculator provides estimates for planning purposes only, based on effective property tax rates (actual median taxes paid divided by median home values). In Kentucky, property is assessed at 100% of fair cash value, but the final tax bill is determined by overlapping state, county, city, school, and special district rates. This calculator uses historical “effective rates” to bypass these complex local millage tables.
What this calculator does not account for:
- Non-primary residences or commercial property.
- Automatic state tax rate adjustments. If aggregate property values spike, the state government automatically lowers the state’s portion of the property tax rate (currently 10.3 cents per $100 for 2026).
How to get an accurate estimate:
- Find your home’s Fair Cash Value on your local Property Valuation Administrator (PVA) portal.
- Subtract the $49,100 Homestead Exemption (if you are 65+ or totally disabled).
- Multiply the remaining value by your local consolidated tax rate, and divide by 100.
