On $9,238 of overtime premium

You save $2,032, but Massachusetts takes back $462

Worked on Massachusetts's own average wage ($100,083, about $48/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 Massachusetts charges anyway. FICA is never touched: $707 of Social Security and Medicare on those hours.

Massachusetts keeps 23.0% of what the federal deduction gives back.

Overtime and OBBBA in Massachusetts

Does Massachusetts tax my overtime in 2026?
Yes. Massachusetts doesn't let the OBBBA deduction reduce its own tax for 2026, so it still applies its income tax (5%–9%) to those hours: you get $2,032 back federally while Massachusetts takes $462 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 $707 in Social Security and Medicare on those hours regardless.
What do I actually save in Massachusetts?
On $100,083 of straight-time pay plus $9,238 of overtime premium: $2,032 off your federal bill, less $462 that Massachusetts takes. Real net effect of the deduction: $1,570.
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.
