Kentucky does not tax Social Security benefits

Kentucky is one of the states that does not impose a state income tax on Social Security benefits. If you receive Social Security retirement, survivor, or disability payments, you will not owe Kentucky state income tax on that money. This applies whether you are a full-time resident or a part-time resident who spends significant time in the state.

However, Social Security income may still be taxable at the federal level, depending on your total income for the year. The federal government uses a formula based on your "combined income" — which includes your adjusted gross income, nontaxable interest, and half of your Social Security benefits — to determine whether any of your benefits are subject to federal tax. Kentucky's lack of a state tax on Social Security does not change your federal tax obligation.

If you moved to Kentucky from another state or are considering the move, this is one less tax burden to manage in retirement. But you will still need to file a federal return if your combined income exceeds the threshold for your filing status.

Key Takeaways

  • Kentucky does not tax Social Security benefits at the state level, so you owe no state income tax on those payments.
  • The federal government may still tax your Social Security benefits if your combined income (adjusted gross income plus half your benefits) exceeds certain thresholds.
  • Combined income thresholds for federal taxation of Social Security are $25,000 for single filers and $32,000 for married couples filing jointly.
  • You may still be required to file a federal tax return even if you owe no Kentucky state tax.

How federal Social Security taxation works

The federal government taxes Social Security benefits using a two-tier system based on your combined income. If your combined income is below a certain threshold, none of your benefits are taxed. If it exceeds the threshold, up to 50 percent of your benefits may be taxable, and if it exceeds a second, higher threshold, up to 85 percent may be taxable.

For a single filer, the first threshold is $25,000 and the second is $34,000. For married couples filing jointly, the thresholds are $32,000 and $44,000. If you are married filing separately, the thresholds are much lower — typically $0 — which means nearly all of your benefits would be taxable. Your combined income includes your wages, interest, dividends, capital gains, and half of your Social Security benefits.

The IRS provides worksheets to calculate how much of your benefit is taxable, and many tax software programs will walk you through this calculation. If you expect your benefits to be taxed, you can request that the Social Security Administration withhold federal income tax from your monthly payment.

Other Kentucky tax considerations for retirees

Kentucky has no state income tax on Social Security, but the state does tax other types of retirement income differently. Distributions from traditional IRAs and 401(k) plans are subject to Kentucky state income tax, though the state offers a tax credit for retirement income that may reduce or eliminate the tax depending on your age and income level.

Pension income from a Kentucky public employee retirement system (such as KERS or SPRS) is exempt from Kentucky state income tax. Pensions from out-of-state public employee systems may also may have access to for exemption, but you will need to verify the specific rules with the Kentucky Department of Revenue.

If you have investment income, rental income, or other earnings in Kentucky, those are subject to state income tax. The state income tax rate is a flat 5.75 percent on taxable income. Understanding which income streams are taxed and which are not can help you plan your retirement finances more effectively.

When you must file a federal return as a Social Security recipient

Even though Kentucky does not tax Social Security, you may still be required to file a federal income tax return. The IRS sets filing thresholds based on your age and filing status. For 2024, a single person age 65 or older must file if their gross income is $15,000 or more. For married couples filing jointly where at least one spouse is 65 or older, the threshold is $26,200.

Your gross income for this purpose includes wages, interest, dividends, and other income, but does not include your Social Security benefits unless they are taxable. If you have any income above these thresholds, you should file a return. Even if you are not required to file, you may want to file anyway if you had federal income tax withheld from your paychecks or other income, because you may be due a refund.

How to estimate your federal tax on Social Security

To estimate whether your Social Security benefits will be taxed at the federal level, add your adjusted gross income, any nontaxable interest you earned, and half of your Social Security benefits. Compare that total to the thresholds for your filing status. If the total is below the threshold, none of your benefits are taxed. If it is above the first threshold but below the second, up to 50 percent of your benefits may be taxable. If it exceeds the second threshold, up to 85 percent may be taxable.

The actual calculation is more complex because the IRS uses a formula that phases in the taxable portion, but this rough estimate will tell you whether you are likely to owe federal tax on your benefits. The Social Security Administration's website includes a benefits estimator tool, and the IRS publishes Publication 915, which walks through the full calculation step by step.

If you expect a large portion of your benefits to be taxable, you can arrange to have federal income tax withheld directly from your Social Security payment. Contact the Social Security Administration to request Form W-4V, which allows you to specify the amount to withhold.

Planning for taxes in retirement in Kentucky

Because Kentucky does not tax Social Security, retirees who move to or remain in Kentucky have an advantage compared to residents of states that do tax benefits. However, this does not mean you can ignore taxes entirely. You will still owe federal tax on taxable Social Security benefits, and you may owe Kentucky state tax on other retirement income such as IRA withdrawals or investment earnings.

A comprehensive retirement tax strategy should account for all income sources and all tax obligations. If you are receiving multiple types of income — Social Security, a pension, IRA distributions, and investment income — the order in which you withdraw from each source can affect your total tax bill. Some retirees benefit from working with a tax professional to coordinate withdrawals and minimize their overall tax burden.
