Kentucky Salary & Tax Calculator
See what you actually take home in Kentucky. This calculator is pre-filled with Kentucky's 4% flat state income tax rate so you can get a fast, realistic estimate.
Kentucky is a flat-tax state, applying a single 4% rate to taxable income no matter how much you earn — a much simpler structure than progressive-bracket neighbors. That rate is meaningfully lower than Virginia's 5.75% top bracket and Ohio's graduated system, but higher than Indiana's flat 3.05%, and of course higher than Tennessee, which has no state tax on wages at all. What makes Kentucky's paycheck math more complicated than the flat state rate alone is local government: many Kentucky cities and counties layer on their own occupational license fee against wages, often in the 1%-2.2% range, with larger metros like Louisville near the top of that range. That means two people earning the same salary in different Kentucky towns can see noticeably different withholding even though the state rate is identical. Below, the tax rate field is pre-set to 4% as a state-only baseline — if you know your city or county's occupational tax rate, add it to get a more realistic combined effective rate.

How the flat state rate and local occupational taxes combine to shape your take-home pay.
How it Works
Strips estimated federal and Kentucky flat state tax, plus common pre-tax deductions, from your gross pay to show your actual Kentucky take-home pay.
The Formula
Net Pay = Gross Pay − (Federal Tax + 4% Kentucky Flat Tax + Local Occupational Tax, if any + Pre-tax Deductions).
Pro Tip
Check your city or county's occupational license fee before comparing job offers within Kentucky — it can add a meaningful percentage on top of the flat 4% state rate depending on where you work.
