Kentucky Paycheck Tax Calculator: How Kentucky Withholding Works
A Kentucky paycheck calculator has to get two
taxes right: the 3.5% state tax and the local occupational tax
where you work. On your pay stub the state tax usually appears as
SIT or KY state withholding,
and the local tax as a separate line with the city or county name.
Our pay stub abbreviations list
explains the other codes.
Federal Withholding for Kentucky Paychecks
Federal withholding uses your Form W-4 and the 2026 federal
brackets. The calculator supports filing status, Step 2(c), Step 3
credits and Step 4(a), 4(b) and 4(c). If you claim the new overtime
or tips deductions, our
W-4 Step 4(b) worksheet guide
shows how to enter them, and our
2026 federal tax withholding guide
covers the rest.
Working Across State Lines
Kentucky has reciprocity with
Illinois,
Indiana,
Michigan,
West Virginia
and Wisconsin,
with Virginia
for daily commuters and with qualifying
Ohio
residents. Those workers claim exemption on the K-4 and pay their
home state instead, but local occupational tax where they work can
still apply. Commuters from
Tennessee and
Missouri
pay Kentucky tax on Kentucky wages.
Bonuses
Bonuses are subject to Kentucky withholding at 3.5%, local
occupational tax, federal withholding (usually a flat 22% on
separately paid bonuses) and FICA. See
why bonuses are taxed so high.
Employer Payroll Costs in Kentucky
Employers pay state unemployment tax
on the first $12,000 of each employee's wages in 2026. Most new
employers pay 2.7% and new construction employers 9%; experienced
rates run from 0.3% up to 9%. Employers also pay their share of
Social Security and Medicare and federal unemployment tax. None of
it comes out of your pay. At year-end, our
W-2 form generator
can use the same wage and withholding totals.
Why Your Actual Kentucky Paycheck May Differ
This calculator is a close estimate, not your employer's payroll
run. Local taxes vary by city, county and school district, and some
cities cap or define taxable wages differently. Benefit elections,
year-to-date wages and a 27th biweekly payday in some years can
also move the result a little.
Three-paycheck months
change monthly cash flow but not the tax on each check. For a full
checklist, see why your paycheck is lower than expected.
