Kentucky Paycheck Calculator 2026 — 3.5% Flat Tax & Take-Home Pay

Kentucky's income tax fell again on January 1, 2026 — House Bill 1 cut the flat rate from 4% to 3.5%, the latest step down from 5% in 2022. Social Security benefits are not taxed at all. See the full stack: state, federal and FICA — free, private, no sign-up.

How Kentucky Paychecks Work

1. Federal tax: progressive brackets 10%–37% minus the $16,100 standard deduction (single, 2026) — same as everywhere.
2. FICA: 6.2% Social Security (up to the $184,500 wage base) + 1.45% Medicare — same as everywhere.
3. State tax: 3.5% flat. One rate on all Kentucky taxable income — no brackets (KRS 141.020). House Bill 1 (2025) cut the rate from 4% to 3.5% from January 1, 2026, the latest step down from 5% in 2022. The $3,360 standard deduction (2026, all filing statuses) applies on your return. Withholding elections go on Form K-4.

Worked Example: $85,000 Single Filer

Kentucky vs Texas vs California on $85,000

The same single filer keeps $65,652 in Kentucky against $68,627 in Texas and $64,007 in California. Kentucky's 3.5% flat costs $114 a paycheck versus the no-tax states — and beats California by $1,645 a year on this salary. Model any state in the calculator.

Federal Withholding on a Kentucky Paycheck

Only one income tax touches a Kentucky paycheck: the federal one. Withholding follows the IRS percentage method in Publication 15-T, and three inputs drive it: your filing status, the dependents and credits you claim on Form W-4, and any extra withholding you request. Change any of the three and the same salary produces a different stub, which is why two Kentucky workers earning $85,000 can take home different amounts.

Federal tax is progressive, which means it applies in slices, not to the whole salary at once. Only the dollars inside each bracket are taxed at that bracket's rate, so a single filer's effective rate is always lower than their top marginal rate. The standard deduction then removes a further slice of income from tax entirely before the brackets even start. Pre-tax items shrink the taxable wage base further: 401(k) contributions and health premiums taken pre-tax reduce the wages the percentages apply to, though the exact treatment differs by deduction type, so read your stub labels rather than assuming.

Our US paycheck calculator models this with an editable withholding percentage instead of hard-coding tables that Congress and inflation adjust every year. If you want the precise official arithmetic for the current year, Publication 15-T is the source the payroll industry itself uses.

FICA: the Two Lines That Always Appear

Below the federal line sit two flat deductions that behave nothing like income tax. Social Security takes 6.2% of wages up to the Social Security Administration's annual wage base, a cap it resets every year. Medicare takes 1.45% of all wages with no cap, plus an additional 0.9% on earnings above $200,000 for single filers ($250,000 joint) — those thresholds are set in statute, not adjusted annually. Your employer matches the 6.2% and the 1.45% dollar for dollar; the additional 0.9% is employee-only.

On the $85,000 example: Social Security is $85,000 x 0.062 = $5,270, comfortably below any recent wage-base cap, and Medicare is $85,000 x 0.0145 = $1,232.50. Together with federal withholding that is the entire deduction stack on a Kentucky stub. There is no third line, which is exactly the point of the next section.

What Kentucky Does Differently

Kentucky has been cutting its flat rate on a schedule: 5% in 2022, 4.5% in 2023, 4% in 2024–2025, and 3.5% from January 1, 2026 under House Bill 1, with a stated goal of eventually eliminating the individual income tax entirely. Further cuts need two budget tests met at the end of a fiscal year, so the next possible cut (to 3%) could not take effect before January 1, 2028. The catch is local: most cities and counties levy occupational license taxes on wages — often 1%–2.5% — on top of the state rate. Kentucky does not tax Social Security benefits. The state return (Form 740) is due April 15.

Overtime and Pay-Frequency Math

Kentucky follows the federal Fair Labor Standards Act: non-exempt employees earn 1.5x their regular rate for hours over 40 in a week, with no stricter state daily-overtime rule on top. At $30/hour and a 45-hour week: 40 x $30 = $1,200 straight time, 5 x $45 = $225 overtime, $1,425 gross for the week. Salaried exempt employees are outside this rule under the duties-and-salary-basis test, so a $85,000 salary means $85,000 of gross regardless of hours.

Pay frequency then decides the per-check number without changing the annual total. On $85,000: weekly (52) = $1,634.62; biweekly (26) = $3,269.23; semi-monthly (24) = $3,541.67; monthly (12) = $7,083.33. The existing $85,000 example uses biweekly, the most common Kentucky schedule. Note that overtime and bonuses can push individual checks into higher withholding on that check alone; withholding per check annualizes the amount, so a spike check withholds as though you earned at that pace all year, with the balance settling at filing time.

New to Kentucky Paychecks: Reading Your First Stub

A first Kentucky pay stub surprises newcomers in two ways: there is no state line at all, and the federal and FICA lines look larger than expected because nothing else shares the load. Read it top to bottom. Gross is what you earned. Pre-tax items come off next. FITW (federal income tax withheld) follows your W-4. Then the two FICA lines. The remainder is net. The year-to-date column repeats the same stack cumulatively, which is how you spot a drift early — if YTD federal withholding looks high relative to gross in March, file a new W-4 rather than waiting until filing season. Anyone arriving mid-year should set the W-4 for the new situation on day one: settings calibrated to a previous state system will systematically over- or under-withhold here. Our US paycheck calculator lets you model the stub before the first one prints.

Tipped, Hourly, and Third-Paycheck Months

Kentucky hospitality runs on tipped wages, and the federal rules are specific. Employers may pay a cash wage as low as $2.13 per hour provided tips bring total hourly earnings to at least the $7.25 federal minimum; if they do not, the employer makes up the difference. Overtime for tipped and hourly staff alike is 1.5 times the regular rate past 40 hours a week. Separately, biweekly earners get two third-paycheck months every year: 26 paychecks cannot divide evenly into 12 months, so two months contain three paydays. The annual total is unchanged, but budgeting monthly on two checks and treating the third as surplus is the standard move. Monthly billers should note the mirror image: semi-monthly schedules never produce a third check, so compare offers on annual gross, not per-check size.

Self-Employed in Kentucky: What Changes

Without an employer there is no withholding at all, so the full stack lands on you four times a year. Self-employment tax replaces both halves of FICA: 12.4% for Social Security up to the annual wage base plus 2.9% for Medicare, with the additional 0.9% over the statutory thresholds exactly as for employees — 15.3% combined before income tax. Half of that combined amount is deductible when computing income tax, which softens it but does not remove it. Federal estimated payments fall on the fixed calendar: January 15, April 15, June 15 and September 15, shifting to the next business day when the date lands on a weekend. Kentucky adds nothing on top: no state estimates, no state return, no state-level equivalent to argue about. Miss a federal quarter and interest accrues from the due date, so new freelancers should set calendar reminders before the first April deadline surprises them. Keep 25 to 30 percent of each client payment in a separate account and the quarters stop hurting.

Bonuses, Commissions, and Supplemental Pay

Not everything on a Kentucky stub follows the salary rules. Bonuses, commissions, severance, and back pay are supplemental wages, and employers may withhold federal tax on them at a flat 22% up to $1 million in a year (37% above that), instead of running them through the W-4 percentage method. That is why a $5,000 bonus can arrive as $3,900 before FICA even though your salary withholding implies a lower rate: $5,000 x 0.22 = $1,100 held back, plus 6.2% Social Security and 1.45% Medicare on top. Kentucky adds nothing either way, so a Kentucky bonus beats the same bonus in California by the state slice alone. The flat rate is only withholding, not the final tax — the actual liability settles at filing time against your real marginal rate, which is why bonus-heavy earners in Kentucky often see meaningful refunds. Overtime already covered above counts as regular wages, not supplemental pay, so the two rules never stack on the same dollar.

The Honest Footnote: Total Burden Matters

The state rate is only half the story in Kentucky: occupational taxes in Louisville, Lexington and most other cities add a real layer on top of the 3.5%. Sales tax is 6% statewide. Property taxes are moderate. Remote workers generally owe tax where they physically live.

Living on a Kentucky Paycheck: What Makes Kentucky Different

Kentucky taxes 2026 income at a flat 3.5%, cut from 4% effective January 1, 2026 under HB 1. The standard deduction is $3,360 for single filers in 2026. Most Kentucky cities and counties levy an occupational license tax on wages — Louisville Metro 2.2% for residents (1.45% non-residents), Lexington-Fayette 2.25%.

Beyond federal tax and FICA, Kentucky takes its own slice: Local occupational license tax (0.5%–2.5% depending on county/city (Louisville Metro 2.2% for residents)). These are employee-paid deductions that show up as separate lines on your stub.

In 2026, the minimum wage in Kentucky is $7.25/hr — the federal floor; Kentucky has no higher state minimum wage.

Kentucky lets you exclude up to $31,110 per person of retirement income (pensions, 401(k), IRAs) from state tax, and Social Security benefits are fully exempt (KRS 141.019; Schedule P).
