No Tax on Overtime in Wisconsin (2025-2028)

On $6,108 of overtime premium

You save $1,311, but Wisconsin takes back $363

Worked on Wisconsin's own average wage ($66,172, 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 Wisconsin charges anyway. FICA is never touched: $467 of Social Security and Medicare on those hours.

Wisconsin keeps 28.0% of what the federal deduction gives back.

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

Overtime and OBBBA in Wisconsin

Does Wisconsin tax my overtime in 2026?

Yes. Wisconsin doesn't let the OBBBA deduction reduce its own tax for 2026, so it still applies its income tax (3.5%–7.65%) to those hours: you get $1,311 back federally while Wisconsin takes $363 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 $467 in Social Security and Medicare on those hours regardless.

What do I actually save in Wisconsin?

On $66,172 of straight-time pay plus $6,108 of overtime premium: $1,311 off your federal bill, less $363 that Wisconsin takes. Real net effect of the deduction: $948.

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.
