No Tax on Overtime in Iowa (2025-2028)

On $5,857 of overtime premium

You save $984, but Iowa takes back $351

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, but not your state base, so Iowa charges anyway. FICA is never touched: $448 of Social Security and Medicare on those hours.

Iowa keeps 36.0% of what the federal deduction gives back.

Overtime and OBBBA in Iowa

Does Iowa tax my overtime in 2026?

Yes. The OBBBA deduction is federal: it cuts your federal tax, not your state base. Iowa still applies its 6.0% income tax to those hours, so you get $984 back federally while Iowa takes $351 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 $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, less $351 that Iowa takes. Real net effect of the deduction: $633.

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.
