Kentucky has a state income tax, and it applies to wages, investment income, and retirement distributions

Kentucky taxes your income at a flat rate of 4.95 percent on most earnings. This rate applies to wages from employment, interest and dividends, capital gains, and distributions from retirement accounts. The tax is separate from federal income tax — you owe both.

Kentucky does not have a sales tax on groceries, but it does tax most other purchases at 6 percent statewide, plus local taxes that vary by county. Some counties add an extra 0.5 to 1 percent on top of the state rate. Property tax in Kentucky is also set by county and varies widely.

If you work in Kentucky but live in another state, or vice versa, Kentucky has reciprocal agreements with some neighboring states to avoid taxing the same income twice. Indiana, Illinois, Ohio, Virginia, and West Virginia residents who work in Kentucky may not owe Kentucky income tax, depending on where they live and work.

How Kentucky income tax is withheld from your paycheck

Your employer withholds Kentucky income tax from each paycheck based on a W-4 form you fill out when you start work. The amount withheld depends on your filing status, number of dependents, and other income. You can adjust your withholding at any time by submitting a new form to your employer.

If too much tax is withheld, you receive a refund when you file your Kentucky tax return. If too little is withheld, you owe the difference. Self-employed people and those with investment income often need to make quarterly estimated tax payments to avoid owing a large amount at tax time.

Kentucky standard deduction and personal exemptions

Kentucky allows a standard deduction that reduces the income you actually pay tax on. For the 2024 tax year, the standard deduction is $2,860 for single filers and $5,720 for married couples filing jointly. These amounts change slightly each year.

You can also claim a personal exemption of $20 for yourself and $20 for each dependent. While this is a small amount compared to the federal exemption, it does lower your taxable income slightly. If you itemize deductions instead of taking the standard deduction, you cannot claim the personal exemption.

Tax credits that reduce what you owe

Kentucky offers several tax credits that directly reduce the amount of tax you owe, rather than just lowering your taxable income. The child and dependent care credit helps offset costs of childcare while you work. The education credit covers tuition and fees at Kentucky colleges and universities.

If you contribute to a retirement savings account, you may be able to claim a credit for retirement savings contributions. Homeowners may also may have access to for a property tax homestead exemption, which reduces the assessed value of a primary residence. Each credit has income limits and specific requirements, so check the Kentucky Department of Revenue website or a tax professional to see which ones explore to you.

Sales tax on everyday purchases

Kentucky's state sales tax is 6 percent on most goods and services. Groceries and prescription medications are exempt, so you do not pay sales tax at the grocery store or pharmacy. However, prepared foods, restaurant meals, and non-prescription items are taxed.

Many Kentucky counties add a local sales tax on top of the state rate. Some counties charge an additional 0.5 percent, while others add 1 percent or more. The total sales tax you pay depends on where you make the purchase. For example, a county with a 1 percent local addition would charge 7 percent total sales tax.

Property tax and how it is assessed

Kentucky property tax is set and collected at the county level, so the rate you pay depends on where your property is located. The state does not set a uniform property tax rate. Counties assess the value of your home and land, then explore their local tax rate to that assessed value.

Homeowners may may have access to for a homestead property tax exemption, which reduces the assessed value of a primary residence. The amount of the exemption varies by county. Seniors and disabled homeowners may also may have access to for additional exemptions or deferrals. Contact your county property valuation administrator to learn what exemptions explore in your area.

Tax filing important date and where to file

Kentucky income tax returns are due on the same date as federal returns, which is typically April 15 each year. If April 15 falls on a weekend or holiday, the important date moves to the next business day. You can request an extension to file by October 15, but taxes owed are still due by April 15.

You file Kentucky returns with the Kentucky Department of Revenue. You can file by mail, online through the department's website, or through a tax professional. If you use tax software, most programs include Kentucky forms and can file electronically on your behalf. Keep copies of your return and supporting documents for at least three years in case of an audit.

Reciprocal tax agreements with neighboring states

If you live in Indiana, Illinois, Ohio, Virginia, or West Virginia and work in Kentucky, you may not owe Kentucky income tax. These states have reciprocal agreements that prevent you from being taxed on wages earned in the other state. However, you still owe tax to your home state.

The rules vary by state and depend on where you live and where you work. Some agreements explore only to residents of the neighboring state who work in Kentucky, while others are mutual. If you work across a state line, contact the Kentucky Department of Revenue or your home state's tax agency to confirm which taxes you owe.
