How Kentucky Income Tax Works in 2026
Kentucky taxes all income at a flat 3.5% in 2026, down from a graduated system topping 6% as recently as 2017. The state has cut the rate almost every year since the flat tax arrived, using revenue triggers that fire automatically when the budget allows. Lawmakers have been explicit about the end goal: zero.
The trigger mechanism is the key detail for planning. Each cut depends on the state's rainy-day fund and revenue performance meeting statutory thresholds, so the reductions arrive without new votes when the economy cooperates. For 2026 the rate sits at 3.5%, and further cuts are possible in coming years if surpluses continue.
What Comes Out of Your Kentucky Paycheck
A Kentucky stub shows federal income tax, Social Security at 6.2%, Medicare at 1.45%, and Kentucky state tax at 3.5%. There is no state disability insurance or paid leave payroll tax. One Kentucky-specific wrinkle: many cities and counties levy local occupational taxes on wages, so some workers see a small local line that is not technically an income tax but feels like one.
Pre-tax 401(k), HSA, and health premium contributions reduce Kentucky taxable income along with federal, saving 3.5 cents per dollar at the state level. With the rate falling nearly every year, each year's savings are slightly smaller than the last, which is a good problem to have.
Worked Example: A $75,000 Salary in Louisville
Take a single filer in Louisville earning $75,000 a year, paid biweekly. Federal tax is about $7,670, FICA takes $5,737.50, and Kentucky's 3.5% flat tax comes to roughly $2,625 before the state standard deduction. Here is the annual breakdown.
| Gross Pay | $75,000.00 |
| Federal Income Tax | ~$7,670.00 |
| Social Security (6.2%) | $4,650.00 |
| Medicare (1.45%) | $1,087.50 |
| Kentucky State Tax | ~$2,625.00 |
| Net Annual Pay | ~$58,967.50 |
That leaves about $2,268 per biweekly paycheck against gross pay of $2,884.62, an effective total rate near 21.4% before any local occupational tax. Kentucky's state slice is about 3.5% of gross pay, and the steady march of trigger cuts means next year's slice will likely be thinner.
Kentucky Paycheck Details Worth Knowing
Watch for local occupational taxes
Kentucky cities and counties can levy occupational license taxes on earnings, which show up as a separate withholding line in places like Louisville and Lexington. They are not state income tax, but they reduce take-home all the same, so check your stub.
A rate with an expiration date in mind
Kentucky's triggers have fired repeatedly since 2018, taking the rate from 5% to 3.5%. State leaders want to reach zero eventually, which would put Kentucky alongside Tennessee as a no-tax Southern state.
Minimum wage and overtime
Kentucky follows the federal $7.25 minimum wage with no higher state floor. Overtime is time and a half past 40 hours under federal law.
Common Paycheck Mistakes in Kentucky
- Using an old rate like 4% or 4.5% for 2026. The triggers keep firing, so always check the current-year figure.
- Ignoring local occupational taxes, which can add 1% to 2% in some Kentucky cities on top of the state rate.
- Assuming the flat rate means the triggers are done. More cuts are possible whenever revenue conditions are met.
- Comparing Kentucky to Tennessee on state rate alone. Tennessee has no wage tax at all, so the gap is the full 3.5% before local taxes.
- Forgetting pre-tax deductions still help. Even at 3.5%, sheltering income saves real money at both the state and federal level.
