What Is a Bonus Tax and Why Does It Matter in Kentucky?

Bonuses are extra payments from employers, often called supplemental income. The IRS and Kentucky tax these differently than regular wages, which can increase your tax bill. Knowing how bonus taxes work helps you budget better in 2025.

In Kentucky, bonuses face federal and state withholding, plus Social Security and Medicare taxes. Misjudging these rates could leave you with less take-home pay than expected. This section breaks it down simply.

  • Federal Tax Impact: Bonuses are taxed at a flat 22% (or 37% if over $1 million) under the percentage method.
  • Kentucky State Tax: A flat 4.5% applies to all income, including bonuses, in 2025.
  • Why It Matters: Higher tax rates on bonuses reduce your net payout.
