Kentucky has been on one of the most aggressive state income tax reduction paths in the country. Starting from a top marginal rate of 6% and then briefly having a 5% rate, the state moved to a flat 4.5% rate in 2023 and then to 4% in 2024, and to 3.5% for 2026 under HB 1 (2025) — part of a deliberate effort to make Kentucky more competitive with neighboring no-income-tax states like Tennessee and to stem population outflows. Further cuts are possible once the statutory revenue-based reduction conditions are met.
What makes Kentucky’s tax picture more complex than the headline rate suggests is the state’s extensive local occupational tax system. Almost every major city and county in Kentucky levies its own occupational tax, and workers in Louisville or Lexington effectively pay about 5.7–5.75% in combined state and local income taxes. This guide explains Kentucky’s income tax trajectory, how local occupational taxes work, the state’s uniform and grocery-exempt sales tax, property taxes, and retirement income treatment.
Kentucky’s income tax history since 2018 represents one of the most striking state tax reform stories in the country. In 2018, the legislature consolidated Kentucky’s graduated brackets (which topped out at 6%) into a flat 5% rate. Then in 2022, the legislature enacted a mechanism to reduce the flat rate automatically (by up to 0.5 percentage points per year) whenever state budget reserve and revenue conditions are met. The result: the rate dropped to 4.5% for 2023, then to 4% for 2024 and 2025, and HB 1 (2025) set it at 3.5% for 2026. Further reductions depend on the statutory reduction conditions being met.
Kentucky starts with federal adjusted gross income (AGI), then applies Kentucky-specific additions and deductions. Kentucky’s standard deduction is $3,360 per taxpayer for 2026 — lower than the federal standard deduction, meaning Kentucky taxable income is often higher than federal taxable income. Kentucky does not piggyback on the federal itemized deduction system to the same extent; Kentucky allows only the state standard deduction or certain Kentucky-specific itemized deductions.
Kentucky has a comprehensive system of local occupational taxes (often called “payroll taxes” or “net profit taxes”). These are levied by cities and counties on earned income, and virtually every major urban area in the state participates:
Employers are required to withhold local occupational taxes and remit them to the relevant local government. Workers filing taxes must often file both a state Kentucky return and one or more local returns depending on where they live and work.
| Worker Location | State Tax (3.5%) | Local Occup. Tax | Combined Rate | vs. Tennessee (0%) |
|---|---|---|---|---|
| Louisville (resident) | 3.5% | 2.2% | 5.7% | +5.7 ppts |
| Lexington (resident) | 3.5% | 2.25% | 5.75% | +5.75 ppts |
| Rural Kentucky | 3.5% | Varies by locality | 3.5% plus local | Varies |
| Tennessee (Nashville) | 0% | 0% | 0% | — |
Kentucky’s local occupational taxes can significantly close the gap between the headline 3.5% flat rate and the actual combined burden on workers in major cities.
Kentucky’s sales tax is one of the simplest in the country: a flat 6% rate applied uniformly across the state. Unlike most states, Kentucky does not allow cities or counties to add local sales taxes on top of the state rate. What you see in Louisville is what you see in Pikeville. This simplicity is genuinely valuable for businesses operating across multiple locations in the state.
Groceries (food for home consumption) are exempt from Kentucky sales tax — an important consumer benefit, especially for lower-income households. Prescription drugs are also exempt. Kentucky has over recent years expanded its sales tax to cover more services, including some personal services and digital goods, as part of efforts to broaden the tax base while reducing income tax rates. Prepared food at restaurants and fast food is subject to the standard 6% rate.
Kentucky’s state property tax rate itself is low. The bulk of Kentucky property taxes come from county and school district levies. Property in Kentucky is assessed at 100% of fair market value (full market value assessment), unlike some states that assess at a fraction of market value.
Property tax bills depend on the county, city and school district rates applied to your assessed value; check your local property valuation administrator (PVA) for current rates.
Kentucky provides a homestead exemption for homeowners who are 65 or older, or who are totally disabled. The exemption reduces the assessed value of the primary residence by $49,100 for the 2025 and 2026 tax periods (adjusted periodically); it applies to both state and local property taxes. For a senior with a $300,000 home, the $49,100 exemption reduces the taxable value to approximately $250,900.
Kentucky is one of the most generous states in the country for retirees from government employment. Pension income from the following systems attributable to service credit earned before January 1, 1998 is fully exempt from Kentucky income tax (later service falls under the $31,110 pension income exclusion):
For retirees whose government service was before 1998, Kentucky income tax on that pension income is zero; for later service, the $31,110 exclusion applies.
Kentucky fully exempts Social Security benefits from state income tax at all income levels. This matches neighboring states such as Ohio, Indiana, and Illinois — which also exempt Social Security — and is on top of Tennessee having no income tax at all. Kentucky retirees pay $0 in state income tax on Social Security benefits regardless of total income.
Private sector pensions and IRA/401(k) distributions are taxable in Kentucky at the 3.5% flat rate, except that up to $31,110 per person per year of pension and retirement income (pensions, annuities, IRA and 401(k) distributions and similar plans) is excluded. There is no age-based or income-based limit on this exclusion.
| State | State Income Tax | SS Exempt? | Govt Pension Exempt? | Avg Property Tax |
|---|---|---|---|---|
| Kentucky | 3.5% flat | Yes | Pre-1998 service; $31,110 exclusion | ~0.74% |
| Tennessee | None | N/A | N/A | ~0.52% |
| Ohio | 2.75% above $26,050 (2026, HB96) | Yes | Partially | ~1.36% |
| Indiana | 2.95% flat | Yes | Partially | ~0.76% |
| Virginia | 2–5.75% | Partially | Partially | ~0.78% |
Kentucky still has an inheritance tax, but it is much narrower than it appears. Immediate family members — spouses, children, grandchildren, parents, and siblings — are all exempt from Kentucky inheritance tax. The tax only applies to more distant relatives and unrelated beneficiaries. Rates range from 4% to 16% depending on the relationship and the size of the inheritance for those non-exempt heirs. Kentucky has no state estate tax.
