No Tax on Overtime in Missouri

2%–4.7%

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

On $6,133 of overtime premium

You save $1,344, but Missouri takes back $298

Worked on Missouri's own average wage ($66,446, about $32/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 Missouri charges anyway. Missouri lets you deduct federal income tax, and the overtime deduction shrinks your federal bill, so that deduction shrinks too: net, $9 more Missouri tax. FICA is never touched: $469 of Social Security and Medicare on those hours.

Missouri keeps 22.0% of what the federal deduction gives back.

Overtime and OBBBA in Missouri

Does Missouri tax my overtime in 2026?
Yes. Missouri doesn't let the OBBBA deduction reduce its own tax for 2026, so it still applies its income tax (2%–4.7%) to those hours: you get $1,344 back federally while Missouri takes $288 of the very same hours. Missouri lets you deduct federal income tax, and the overtime deduction shrinks your federal bill, so that deduction shrinks too: net, $9 more Missouri tax.
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 $469 in Social Security and Medicare on those hours regardless.
What do I actually save in Missouri?
On $66,446 of straight-time pay plus $6,133 of overtime premium: $1,344 off your federal bill, less $298 that Missouri takes ($288 on the premium and $9 as its deduction for federal tax shrinks). Real net effect of the deduction: $1,046.
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.
