Kentucky Paycheck Calculator

Kentucky's flat income tax rate has been on a deliberate downward path for several years: 5% through 2022, stepping down to 4.5% for 2023-2024, 4.0% for 2025, and now 3.5% for 2026 under House Bill 1 from the 2025 Regular Session. Each step has required its own separate legislation rather than following an automatic formula, so the 3.5% rate for 2026 reflects the most recent successful cut, not a locked-in multi-year plan.

The Kentucky Department of Revenue's own 2026 Withholding Tax Formula document confirms both the 3.5% rate and the $3,360 standard deduction directly, alongside worked withholding examples that this calculator's formula is built to match. Because the rate has moved this often, anyone bookmarking a Kentucky tax figure from a prior year should treat it as potentially stale — this calculator's data reflects the confirmed 2026 figures specifically.

Whether Kentucky continues cutting the rate further in 2027 and beyond depends on future legislative action and state revenue performance, neither of which this calculator attempts to predict — it reflects confirmed, current-year data only.

Every other state calculator on this site that has a standard deduction gives married filers a meaningfully larger figure than single filers — usually roughly double. Kentucky is the deliberate exception: its $3,360 standard deduction for 2026 applies once per tax return, confirmed by both the Kentucky Department of Revenue's own withholding formula and its news release announcing the figure, with no separate, larger married amount listed anywhere in the state's official guidance.

The practical effect is that a married couple with the same total household income as this page's single-filer worked example would see an identical Kentucky state-tax calculation, all else equal, which is unusual enough to call out explicitly rather than let a user assume Kentucky works the same way every other state on this site does.

This calculator models that quirk correctly by using the same $3,360 figure for both the single and married branches, rather than assuming (incorrectly) that Kentucky must double it the way most other states do.

This calculator's Kentucky figures cover federal income tax, Kentucky's flat 3.5% state income tax, and the two federal FICA taxes — the complete set of withholding categories that apply broadly to Kentucky wage earners. Kentucky has no state-run disability insurance or paid-family-and-medical-leave payroll premium, unlike states such as California (SDI) or New Jersey (UI/TDI/FLI), so there's no additional payroll deduction line to model here beyond income tax.

Some Kentucky cities and counties do levy their own local occupational or payroll taxes on top of the state rate — those vary by jurisdiction and aren't collected by the state, so they fall outside what this state-level calculator computes, the same kind of local-tax gap disclosed for states like Indiana and Maryland elsewhere on this site.

A worker comparing take-home pay across job offers in different Kentucky cities should check their specific city or county's local tax rate separately, since this calculator's stateTax figure reflects Kentucky's own income tax only.

Most of Kentucky's largest employment centers run their own occupational license tax on top of the state's 3.5% flat rate, and the two biggest cover a large share of Kentucky's workforce. The Lexington-Fayette Urban County Government publishes an occupational license fee of 2.25% on wages, confirmed directly on the city's own rates-and-forms page. Louisville/Jefferson County's Revenue Commission publicly documents a resident rate of roughly 2.2%, split across a 1.25% city/county fee, a 0.75% Jefferson County Public Schools levy, and a 0.20% TARC transit fee, with a lower 1.45% rate for non-residents who work in Jefferson County but live elsewhere.

These are genuinely large numbers next to a 3.5% state rate — for a $75,000 Louisville resident, 2.2% works out to roughly $1,650 a year withheld on top of everything this calculator already computes, and Lexington's 2.25% comes out close behind it. Every one of ADP, PaycheckCity, and SmartAsset's own Kentucky paycheck calculators has the identical gap: none of them automatically applies a specific city or county's occupational tax either, because it depends on the employer's actual work location, not just the state someone lives in.

If a job offer is in Louisville, Lexington, or another Kentucky city or county with its own occupational license tax, treat this calculator's net-pay figure as before that local deduction — subtract the applicable local rate from taxable wages separately, or check with the employer's payroll department for the exact figure withheld.
