Kentucky Taxes: What You Need to Know
Kentucky has a flat 3.5 percent individual income tax rate starting January 2026. This reduction is part of a broader plan established by House Bill 8, passed in 2022, which aims to eliminate the state’s income tax gradually if certain fiscal conditions are met.
The Kentucky General Assembly has made tax code adjustments over time, including reductions from 5% to 4.5% in 2023 and from 4.5% to 4% in 2024, and the rate now drops to 3.5% in 2026. The Kentucky Department of Revenue has also updated the 2026 withholding formula, which reflects the 3.5% rate and a $3,360 annual standard deduction.
The broader fiscal-responsibility and reserve-fund sentence should be treated as background context rather than a 2026 tax-law update unless you have a current Kentucky government source for those figures.
An Overview of Kentucky Taxes
Federal, State, and Local Tax Withholding
1. Federal Income Tax — Withheld based on your income, filing status, and the information on your W-4 form.
2. State Income Tax — Kentucky’s flat rate for 2026 is 3.5%. All wage earners are taxed at this rate after the standard deduction is applied.
3. Local Taxes — Vary by locality and are often a percentage of your wages.
FICA and State Insurance Taxes
1. Social Security Tax — 6.2% of your wages, up to the 2026 wage base of $184,500. Social Security taxes do not apply to earnings above this threshold.
2. Medicare Tax — 1.45% of all wages. An additional 0.9% applies to earnings over $200,000 for single filers and $250,000 for married couples filing jointly.
3. State Disability Insurance (SDI) Tax — Kentucky does not have a state disability insurance program. No SDI is withheld from employee paychecks in Kentucky.
4. State Unemployment Insurance (SUI/SUTA) Tax — This is an employer-only tax. Employees in Kentucky do not have SUI deducted from their paychecks. For reference:
- 2026 taxable wage base: $12,000 per employee (up from $11,700 in 2025)
- Rate schedule in effect for 2026: Schedule A
- Experienced employer rates: 0.3% to 9.0%
- New employer rate: 2.7% (or 9.0% for new construction employers)

5. Workers’ Compensation Insurance — This is an employer-paid cost, not deducted from employee wages. Kentucky requires workers’ compensation coverage for almost all employers. Rates vary by industry and claims history and are set by the Kentucky Department of Workers’ Claims.

1. Medical Insurance — Premiums are often deducted before taxes.
2. 401(k) Contributions — Contributions are made pre-tax, reducing your taxable income.
3. Health Savings Account (HSA) — Contributions are pre-tax.

Kentucky Tax Brackets 2026
Kentucky uses a flat tax. There are no income brackets — one rate applies to all taxable income.
For 2026:
- State income tax rate: 3.5%
- Standard deduction: $3,360 (increased from $3,270 in 2025, adjusted annually for inflation under KRS 141.081)
Here’s an example:
Assuming a monthly wage of $3,270:
- Compute annual wages: $3,270 × 12 = $39,240
- Subtract the Kentucky standard deduction: $39,240 − $3,360 = $35,880 (Kentucky taxable wages)
- Apply the 3.5% flat rate: $35,880 × 0.035 = $1,255.80 (gross annual Kentucky tax)
- Divide by 12 for monthly withholding: $1,255.80 ÷ 12 = $104.65 per month

Wrapping Up
Kentucky has been on an impressive tax-cutting streak, dropping its flat income tax rate from 5% in 2022 down to 3.5% for 2026, with the long-term goal of eliminating it entirely if the state’s finances allow. It’s a straightforward system with no brackets to navigate. Local taxes vary by area, and there’s no local sales tax on top of the state’s 6% rate. For employees, the paycheck math is simple and getting friendlier every year.
