Kentucky Capital Gains Tax Calculator
Kentucky taxes capital gains as ordinary income at the state level, which means a gain on selling shares, property or other investments is added to your other income and taxed using the Kentucky income tax brackets, with no separate preferential long-term rate like the federal system provides. This calculator estimates the Kentucky state tax on a capital gain by stacking the gain on top of your other taxable income and applying the sourced Kentucky Department of Revenue brackets for tax year 2025, then taking the difference. Enter your gain, your other annual taxable income and your filing status to see the state tax attributable to the gain and the effective rate on it. The result is the Kentucky state portion only; federal capital gains tax, which has separate short-term and long-term rates set by the IRS, is calculated separately. Because the gain stacks on your other income, the same gain is taxed at a higher rate the more you already earn. Some states provide specific exclusions or preferential treatment for certain gains; this tool uses the standard ordinary-income method and links the Kentucky Department of Revenue so you can confirm any special rule that applies to you.

Will Kentucky's income tax rate drop below 4.0%?
Possibly. Kentucky HB 8 (2023) includes a revenue trigger that could reduce the rate from 4.0% to 3.5% effective January 1, 2026, provided the state's general fund revenues meet the required threshold. If the trigger is not met for 2026, it may be evaluated again in subsequent years.
Can Kentucky residents itemize deductions?
Kentucky eliminated most itemized deductions in 2018 as part of its tax reform. A limited set of deductions remains available, but for most taxpayers the standard deduction of $3,160 is the primary offset. Federal itemized deductions are not automatically deductible on the Kentucky return.
