Kentucky Paycheck Calculator

How to estimate your Kentucky take-home pay in 2026

Kentucky applies a flat 3.5% state income tax rate on wages after a $3,360 standard deduction. This calculator estimates your 2026 net pay after federal withholding, FICA payroll taxes, and Kentucky state tax so you can plan monthly expenses and compare job offers with confidence.

Enter your annual salary or build it from hourly wages using our gross pay calculator. If you receive 26 paychecks per year, the biweekly pay calculator shows how gross and net amounts spread across the calendar. For federal tax details and dependent credits, see the income tax calculator and salary calculator.

What gets deducted from a Kentucky paycheck

A typical Kentucky W-2 paycheck includes three layers of mandatory withholding plus any voluntary deductions you elect through your employer:

• Federal income tax: Calculated from 2026 IRS brackets, your W-4 filing status, and qualifying child tax credits.
• FICA taxes: Social Security at 6.2% (capped at the 2026 wage base of $184,500) and Medicare at 1.45%, with an additional 0.9% on wages above $200,000 for single filers. Use our FICA tax calculator to isolate these amounts.
• Kentucky state income tax: A flat 3.5% applied to gross wages after pre-tax deductions and the Kentucky standard deduction.

Kentucky cities and counties may levy occupational license taxes on wages, but this calculator models state-level tax only. Pre-tax 401(k) contributions and HSA deposits reduce gross wages before Kentucky taxable income is calculated.

How Kentucky flat tax is calculated

Kentucky taxable income starts with gross wages after pre-tax deductions, then subtracts the state standard deduction before applying the flat rate:

Because the rate is flat, your Kentucky marginal rate stays at 3.5% regardless of income level. That predictability makes Kentucky competitive with other flat-tax states like Indiana (2.95%) and Illinois (4.95%).

Kentucky taxable income in this calculator

Kentucky taxable income is based on gross wages after pre-tax 401(k) and HSA contributions, minus the $3,360 standard deduction. This approach differs from states that tax federally taxable wages directly, such as Iowa.

Worked example: $65,000 salary, single, biweekly, 5% 401(k)

Consider a single Kentucky employee earning $65,000 per year, paid biweekly, contributing 5% to a traditional 401(k), with no dependents or health premium deductions:

1. Pre-tax 401(k): $65,000 x 5% = $3,250 per year
2. Gross after pre-tax: $65,000 - $3,250 = $61,750
3. Kentucky taxable income: $61,750 - $3,360 (standard deduction) = $58,390
4. Kentucky state tax: $58,390 x 3.5% = $2,043.65 per year
5. FICA: Social Security and Medicare on the full $65,000 gross (401(k) does not reduce FICA wages)
6. Estimated net per paycheck: About $1,903.99 biweekly after all withholdings
