No Tax on Overtime in Kentucky

3.5%

The deduction is federal. Kentucky still charges its own tax on those same hours.

On $5,775 of overtime premium

You save $877, but Kentucky takes back $202

Worked on Kentucky's own average wage ($62,567, about $30/hour per BLS) with 8 overtime hours a week for 48 weeks. The OBBBA deduction cuts your federal tax, but not your state base, so Kentucky charges anyway. FICA is never touched: $442 of Social Security and Medicare on those hours.

Kentucky keeps 23.0% of what the federal deduction gives back.

Overtime and OBBBA in Kentucky

Does Kentucky tax my overtime in 2026?
Yes. Kentucky doesn't let the OBBBA deduction reduce its own tax for 2026, so it still applies its income tax (3.5%) to those hours: you get $877 back federally while Kentucky takes $202 of the very same hours.
So is overtime actually tax-free?
Not quite, and the name oversells it. The deduction covers only the PREMIUM half of time-and-a-half, caps at $12,500 for a single filer, phases out above $150,000 of income, and never touches FICA: in this example you pay $442 in Social Security and Medicare on those hours regardless.
What do I actually save in Kentucky?
On $62,567 of straight-time pay plus $5,775 of overtime premium: $877 off your federal bill, less $202 that Kentucky takes. Real net effect of the deduction: $675.
Where does this show up on my W-2?
Your employer reports qualified overtime in W-2 box 12 under code TT. That figure is what carries to Schedule 1-A; if the box is empty, ask your employer to correct it before you file.
