No Tax on Overtime in New Mexico (2025-2028)

On $5,828 of overtime premium

You save $946, but New Mexico takes back $344

Worked on New Mexico's own average wage ($63,135, about $30/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 New Mexico charges anyway. FICA is never touched: $446 of Social Security and Medicare on those hours.

New Mexico keeps 36.0% of what the federal deduction gives back.

Overtime and OBBBA in New Mexico

Does New Mexico tax my overtime in 2026?

Yes. The OBBBA deduction is federal: it cuts your federal tax, not your state base. New Mexico still applies its 5.9% income tax to those hours, so you get $946 back federally while New Mexico takes $344 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 $446 in Social Security and Medicare on those hours regardless.

What do I actually save in New Mexico?

On $63,135 of straight-time pay plus $5,828 of overtime premium: $946 off your federal bill, less $344 that New Mexico takes. Real net effect of the deduction: $602.

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.
