Kentucky tax FAQ

How much state income tax will I pay in Kentucky?

Kentucky state income tax depends on your taxable income and filing status. Use the calculator above for an exact estimate.

What's the difference between federal and Kentucky state tax?

Federal income tax is collected by the IRS using nationwide brackets (10%–37%). Kentucky state income tax (where applicable) is separate and uses its own brackets and deductions. Both apply to most Kentucky residents.

Are these the 2025 or 2026 tax brackets?

The calculator uses tax year 2025 federal brackets — the figures you'll use to file in early 2026. The IRS adjusts brackets annually for inflation; we update when 2026 figures are released.

Should I take the standard deduction or itemize?

Take whichever is larger. The 2025 standard deduction is $14,600 (single), $29,200 (married filing jointly), or $21,900 (head of household). Itemize if your mortgage interest, state and local taxes (capped at $10,000), and charitable donations exceed that amount.
