Best pick for your situation
If you have a car to sell: trade it in at the dealer when the private-sale price is less than $600 higher. Kentucky gives a trade-in credit, so a $10,000 trade cuts state tax on a $30,000 car from $1,800 to $1,200. If a private buyer would pay more than $10,000 + $600, selling privately comes out ahead.
The math:
- $30,000 car, no trade-in: $1,800 state tax at 6%
- $30,000 car, $10,000 trade-in: $1,200 state tax (trade-in rule: allowed)
- Kentucky charges a statewide rate only (0% county or municipal auto sales tax on vehicle purchases; the local rate field stays at 0%).
