Kentucky: take-home, federal, state & FICA
Calculation parameters: Single filer, standard deduction ($3,270), $75,000 annual salary, 24 pay periods. Model accounts for the 2026 reduction to a 3.5% flat tax. Local tax illustrates a 2.2% metropolitan rate. Data sourced from the Kentucky Department of Revenue.
The Kentucky Department of Revenue enforces a flat individual income tax system, having entirely eliminated its progressive brackets. Crucially, under the provisions of House Bill 1 passed in 2025, Kentucky's flat tax rate was statutorily reduced to 3.5% effective January 1, 2026.
Kentucky provides a state standard deduction ($3,270 for 2026). A single earner making $75,000 applies the 3.5% flat rate against their remaining $71,730 of taxable income, generating an estimated annual state tax liability of $2,510. To ensure accurate withholding under the new 3.5% rate, employees must submit Form K-4 to their payroll department.
What fundamentally distinguishes Kentucky from other flat-tax states is its intense reliance on local occupational license taxes. Counties and municipalities across the state levy taxes directly on gross payroll wages.
This tax is completely unavoidable and is determined strictly by the geographic location where the work is performed. For example, an employee working within the Louisville Metro area is subjected to a 2.2% local occupational tax. Applied directly to a $75,000 salary, this strips an additional $1,650 annually from the worker's pay. Lexington enforces a similar 2.25% rate. This functions as a massive secondary layer to the 3.5% state tax, pushing the true effective tax rate near 5.7% for many urban workers.
Kentucky charges 4% on every dollar of taxable income, with no bands to cross, once the $3,270 standard deduction has come off. On $75,000 that works out to $2,689, an effective 3.59% of gross, and nothing at all is due below $3,479.
Annual take-home at six salary points for a single filer deferring 6% into a 401(k). The KY column climbs in a straight line from $1,373 to $7,389, because the same rate applies at both ends.

Take-home pay is gross salary minus five separate withholdings, each with its own rule and its own base. Two are federal and fixed nationwide, two are FICA payroll taxes with their own ceilings, and one is set by Kentucky. Kentucky applies a single flat rate of 4% to taxable income, so unlike a progressive state your marginal and average state rates converge as income rises. On $62,000 the state takes $2,200, an effective 3.55% of gross. A flat rate makes the arithmetic simple but it applies from the first taxable dollar, so the deduction matters more than the bracket structure. Note also that the 401(k) contribution comes out before federal income tax is computed but not before Social Security and Medicare — a detail that trips up most hand calculations.
Take-home = Gross − 401(k) − Federal income tax − Social Security − Medicare − State taxFederal = brackets applied to (gross − 401(k) − $15,000 standard deduction)State income tax = (gross − 401(k) − state standard deduction) × 4%where:
Assumptions: Single filer, standard deduction, 6% traditional 401(k), no other pre-tax benefits, credits or local income tax. Health premiums, HSA contributions and city taxes (where they exist) would each change the result. 2026 federal figures.

Rather than a round number, this example uses the salary Kentucky's own housing costs imply: a median-priced $215,000 home carries a $1,436 monthly payment, and the 28% front-end ratio lenders underwrite to puts that within reach at about $62,000 a year. Here is where that salary actually goes for a single filer contributing 6% to a traditional 401(k).

Total tax burden is $11,899, an effective 19.2% of gross — of which Kentucky takes 3.55%. The $3,720 401(k) deferral is not a tax; it is still your money.
