No Tax on Overtime in Colorado (2025-2028)

On $7,768 of overtime premium

You save $1,709, but Colorado takes back $342

Worked on Colorado's own average wage ($84,157, about $40/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 Colorado charges anyway. FICA is never touched: $594 of Social Security and Medicare on those hours.

Colorado keeps 20.0% 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 Colorado

Does Colorado tax my overtime in 2026?

Yes. Colorado doesn't let the OBBBA deduction reduce its own tax for 2026, so it still applies its income tax (4.4%) to those hours: you get $1,709 back federally while Colorado takes $342 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 $594 in Social Security and Medicare on those hours regardless.

What do I actually save in Colorado?

On $84,157 of straight-time pay plus $7,768 of overtime premium: $1,709 off your federal bill, less $342 that Colorado takes. Real net effect of the deduction: $1,367.

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.
