Kentucky State Income Tax: 2026 Flat Rate
Kentucky state income tax is a flat 3.5% for the 2026 tax year, down from 4.0% in 2025. The single rate applies to all taxable income, so a resident earning $50,000 and one earning $500,000 face the same marginal rate. On top of the state tax, most Kentucky workers also pay a local occupational license tax to their city, county, or both, which can add roughly 1% to 2.75% on wages.
Kentucky is one of about 15 states with a flat individual income tax rate. The rate has been falling on a schedule tied to state revenue conditions rather than dropping automatically each year, which matters for anyone trying to project a 2027 or later liability.
What is the Kentucky income tax rate for 2026?
The Kentucky individual income tax rate for 2026 is a flat 3.5%, applied to net taxable income on Form 740. It replaced the 4.0% rate that applied to 2025 income (returns filed in 2026). Kentucky uses a single rate for all filers and all income levels, so there are no brackets to look up.
Because the rate is flat, your effective state rate depends mainly on deductions and exclusions, not on how income is layered. The state offers a standard deduction of $3,360 for 2026, an increase from $3,270 in 2025, and adjusts it annually. Filers may itemize instead, though Kentucky itemized deductions differ from the federal set.
| Tax year | Kentucky flat rate | Notes |
|---|---|---|
| 2018–2022 | 5.0% | Flat rate replaced the old graduated brackets (top 5.8%–6.0%) |
| 2023 | 4.5% | First trigger-based reduction |
| 2024 | 4.5% | No further cut that year |
| 2025 | 4.0% | Reduction ratified for the year |
| 2026 | 3.5% | Current rate, confirmed by 2025 legislation |
| 2027 | 3.5% (as of mid-2026) | Revenue trigger for a cut to 3.0% was not met |
Rates and thresholds can change if the legislature acts, so confirm the current figure with the Kentucky Department of Revenue before filing.
How the rate reductions are triggered
Kentucky’s rate cuts are not automatic. They depend on two revenue conditions being met in a fiscal year, a structure set up under House Bill 8 in 2022 and continued in later sessions. When both conditions are satisfied, the legislature may lower the rate by up to 0.5 percentage points, typically effective the following January 1.
The two conditions are, in plain terms:
- The Budget Reserve Trust Fund (the “rainy day” fund) balance must equal at least 10% of General Fund receipts at the end of the fiscal year.
- General Fund receipts must exceed appropriations by at least the amount of revenue a one-percentage-point rate cut would cost.
The 2026 cut to 3.5% was ratified by House Bill 1 in the 2025 session after the conditions were met. For 2027, the state reported that General Fund revenue fell about $7.5 million short of the threshold, so the rate did not drop to 3.0%. Lawmakers have disagreed over the reading of that shortfall, and legislation has been introduced to allow a smaller 0.25-point cut when the state comes close, though timing depends on future fiscal-year results.
The long-run direction is toward zero, but each step depends on revenue. Treat any rate below 3.5% for future years as conditional until the legislature confirms it.
Local occupational license taxes
Separate from the state income tax, most Kentucky workers pay a local occupational license tax, often called an occupational license fee, on wages earned within a city or county. Kentucky is unusual in that both cities and counties can levy this tax, and the two can stack on the same paycheck. These are not part of the 3.5% state rate and are not filed on Form 740.
The occupational tax generally applies to gross wages with few or no deductions, and it is usually withheld by the employer based on where the work is performed. Rates vary widely by jurisdiction.
| Jurisdiction | Approximate 2026 rate on wages | Detail |
|---|---|---|
| Louisville Metro (resident) | 2.2% | 1.45% Louisville Metro + 0.75% Jefferson County Public Schools |
| Louisville Metro (nonresident working in metro) | 1.45% | School board portion generally does not apply |
| Lexington-Fayette | 2.25% | Combined city/county occupational fee |
| Kentucky counties (2025 data) | 0.50% to 2.5% | 87 counties levy on payroll; median around 1% |
Where you live versus where you work both matter. Someone living in a county with a payroll tax but commuting to a city with its own fee may owe both, subject to local rules and any credits. Confirm the exact rate with the specific city or county, because these change independently of the state rate.
Pension and retirement income exclusion
Kentucky excludes a set amount of qualifying retirement income per person from state tax, reported on Schedule P. For 2026 the exclusion is generally $31,110 per taxpayer, so a married couple who each receive qualifying income and file jointly may shelter up to $62,220 combined. Amounts above the exclusion are taxed at the flat 3.5% rate.
Qualifying income can include distributions from pensions, 401(k)s, IRAs, and similar plans. Social Security benefits are fully exempt from Kentucky income tax and are not counted against the exclusion. See Form 1099-R, which reports retirement and pension distributions, for the figures that flow onto a Kentucky return.
Retirees from federal, Kentucky state, or local government service may exclude more than $31,110 if part of their pension is based on service performed before January 1, 1998. That portion can be fully exempt, and Schedule P walks through the calculation. Legislation has been proposed to raise the general exclusion above $31,110, so check the current amount for the filing year.
Residency: who files and on which form
Kentucky residents report all income on Form 740, the resident return, regardless of where the income was earned, and claim a credit for tax paid to other states where applicable. Nonresidents and part-year residents use Form 740-NP, reporting the Kentucky-taxable share of their income.
Residency generally turns on domicile, your permanent home, plus physical presence. Someone who maintains a Kentucky home and returns to it is typically a resident even during time spent working elsewhere. Part-year residents file Form 740-NP for the year they move in or out.
Kentucky has reciprocity agreements with several neighboring states, including Illinois, Indiana, Ohio, Virginia, West Virginia, Michigan, and Wisconsin, subject to each agreement’s terms. Under reciprocity, residents of those states who work in Kentucky may owe income tax only to their home state on those wages, though the local occupational tax can still apply. Reciprocity does not remove the occupational license fee.
Kentucky income tax vs the federal system
Kentucky’s flat 3.5% structure differs sharply from the federal graduated brackets. Federal income tax rises through multiple brackets, while Kentucky applies one rate to taxable income after its own deductions. For a fuller comparison of the two systems, see state vs federal income tax.
Kentucky starts from federal adjusted gross income and then applies state-specific additions, subtractions, and the pension exclusion. Because the state rate is flat, planning levers that shift income between years save less at the state level than they would in a bracketed state such as Ohio. For context on how state burdens compare nationally, see the State and Local Tax Burden Report 2026, and for states that levy no wage tax at all, see states with no income tax in 2026.
Frequently asked questions
What is Kentucky’s income tax rate in 2026?
Kentucky’s individual income tax rate for 2026 is a flat 3.5%, down from 4.0% in 2025. The single rate applies to all taxable income on Form 740 regardless of income level. Most workers also owe a separate local occupational license tax to their city, county, or both, which is not part of the 3.5% state rate.
Will Kentucky’s income tax rate drop below 3.5%?
It may, but not automatically. Further cuts depend on revenue triggers: the rainy day fund must reach 10% of General Fund receipts, and receipts must exceed appropriations by the cost of a one-point cut. For 2027 the rate stayed at 3.5% after revenue fell roughly $7.5 million short. Treat any lower future rate as conditional until the legislature confirms it.
Does Kentucky have local income taxes?
Yes, in the form of local occupational license taxes on wages. Both cities and counties can levy them, and they can stack. Louisville residents pay about 2.2% combined and Lexington residents about 2.25%, while county rates range from roughly 0.50% to 2.5%. These are separate from the state’s flat 3.5% and generally apply to gross wages.
Is retirement income taxed in Kentucky?
Kentucky exempts Social Security benefits entirely and excludes about $31,110 of other qualifying retirement income per person for 2026, reported on Schedule P. Married couples filing jointly may shelter up to $62,220 combined. Amounts above the exclusion are taxed at 3.5%. Government retirees with pre-1998 service may exclude more.
Who has to file a Kentucky income tax return?
Kentucky residents file Form 740 and report all income, claiming a credit for tax paid to other states where it applies. Nonresidents and part-year residents file Form 740-NP for their Kentucky-taxable income. Residents of reciprocity states who work in Kentucky may owe wage tax only to their home state, though the local occupational tax can still apply.
What is the Kentucky standard deduction for 2026?
The Kentucky standard deduction is $3,360 for 2026, up from $3,270 in 2025. It is adjusted annually. Filers may itemize instead, but Kentucky itemized deductions differ from the federal list. Because the rate is flat, the deduction reduces taxable income before the single 3.5% rate is applied.
