No Tax on Overtime in Iowa

3.8%

Iowa applies the deduction to its own tax as well — the premium escapes both.

On $5,857 of overtime premium

You save $984 federal and $223 in Iowa

Worked on Iowa's own average wage ($63,455, about $31/hour per BLS) with 8 overtime hours a week for 48 weeks. The OBBBA deduction cuts your federal tax and your Iowa tax too. FICA is never touched: $448 of Social Security and Medicare on those hours.

What the new federal overtime deduction actually saves you — and what it does not.

2025–2028

Federal tax saved: $1,183. FICA still owed on that overtime: $1,234.

Overtime and OBBBA in Iowa

Does Iowa tax my overtime in 2026?
Not on the premium. Iowa allows the OBBBA deduction on its 2026 return, so that part of the premium also comes off your Iowa tax: you save $984 federal and $223 state. Straight-time pay for those hours is taxed as usual.
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 $448 in Social Security and Medicare on those hours regardless.
What do I actually save in Iowa?
On $63,455 of straight-time pay plus $5,857 of overtime premium: $984 off your federal bill, plus $223 off your Iowa tax. Real net effect of the deduction: $1,207.
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.
