What is different in Kentucky:
- Flat 3.5% state income tax on wages — cut from 4.5% in recent years.
- Many cities and counties add their own occupational tax on wages (often 1–2%), not modeled here.
- The 3.5% applies to wages after pre-tax deductions like a 401(k).
- Federal income tax, Social Security and Medicare work exactly as in every other state.
What a Kentucky paycheck looks like at six salaries
Single filer, paid every two weeks, no 401(k) or other deductions, 2026 figures. Every number below comes from the same tested formulas the calculator above uses.
| Salary | Federal income tax | Social Security + Medicare | Kentucky tax | Take-home / year | Take-home / paycheck |
|---|---|---|---|---|---|
| $46,000 | $3,340 | $3,519 | $1,610 | $37,531 | $1,443.50 |
| $66,000 | $5,740 | $5,049 | $2,310 | $52,901 | $2,034.65 |
| $86,000 | $10,090 | $6,579 | $3,010 | $66,321 | $2,550.81 |
| $109,000 | $15,150 | $8,339 | $3,815 | $81,697 | $3,142.17 |
| $139,000 | $22,094 | $10,634 | $4,865 | $101,408 | $3,900.29 |
| $179,000 | $31,694 | $13,694 | $6,265 | $127,348 | $4,897.98 |
Worked example: $82,000, single, paid biweekly
Single filer, paid every two weeks, 5% of salary to a traditional 401(k) — $157.69 per paycheck, $4,100 a year — in Kentucky.
- Taxable income: $82,000 − $4,100 401(k) − $16,100 standard deduction (single) = $61,800.00.
- Federal income tax on that amount: $8,308.00 a year.
- Social Security: $5,084.00; Medicare: $1,189.00. The 401(k) does not reduce these.
- Kentucky state income tax: $2,726.50.
- Take-home: $82,000 − $4,100 − $8,308.00 − $5,084.00 − $1,189.00 − $2,726.50 = $60,592.50 a year, or $2,330.48 per biweekly paycheck.
Worked example: $20 an hour in Kentucky
A single worker earns $20.00 an hour for 37 hours a week: $20.00 × 37 × 52 = $38,480 a year before tax. After federal income tax ($2,438), Social Security ($2,386) and Medicare ($558) ($1,347 of Kentucky tax), take-home is $31,752 a year — about $1,221.23 per biweekly paycheck.
Kentucky vs Tennessee: $86,000
The same single worker earning $86,000, paid biweekly with no 401(k). Kentucky's 3.5% takes $3,010 a year; Tennessee takes $0.
| Kentucky | Tennessee (no income tax) | |
|---|---|---|
| Federal income tax | $10,090 | $10,090 |
| Social Security + Medicare | $6,579 | $6,579 |
| State income tax | $3,010 | $0 |
| Take-home per year | $66,321 | $69,331 |
The Tennessee worker keeps -$3,010 more per year than the Kentucky worker — about -$115.77 per paycheck, before Kentucky's local occupational taxes. To compare every no-tax and flat-tax state side by side, see take-home pay by state. Also see our Tennessee paycheck calculator.
What Kentucky does not tax — and what it does
Kentucky's 3.5% is still falling — lawmakers cut it from 4.5% and tied future cuts to revenue triggers. But the state line isn't the whole story: many Kentucky cities and counties levy their own occupational tax on wages, often another 1–2%, which this calculator can't model. Check your pay stub for a city/county line.
What this page leaves out
Child and dependent credits, itemized deductions, health premiums, 401(k) contributions beyond the examples above, bonuses and overtime are not in the simplified calculator — the full paycheck calculator covers all of them, with Kentucky at its 3.5% flat rate. For exact figures use your employer's payroll system or the IRS Tax Withholding Estimator.
