What Counts (and What Doesn't)
Security runs on thin staffing, so guard OT is abundant — and every premium dollar on your W-2 is deductible. Armed-post differentials and hazard premiums raise the regular rate and the deduction with it. Event staffing through a vendor on 1099 does not qualify; the same events staffed on W-2 do.
The full rules, caps and phase-outs for every deduction are in one table on the OBBBA rules page.
Worked Example
Ben staffs static posts at $20/hour, and call-offs plus event coverage push him to 420 overtime hours a year.
- • Deductible amount: $4,200
- • Federal income tax savings: $504 (at the 12% marginal rate)
- • Per biweekly paycheck: $19
Every dollar of that comes off federal income tax while FICA still applies — the calculator above runs the same caps and phase-outs your return will.

Frequently Asked Questions
Armed post differential — does it raise my deduction?
Yes, when it is part of your regular rate. Differentials fold into the regular rate used to compute overtime premium, so armed or hazard post pay increases the deductible premium on every OT hour.
Do I need to itemize deductions to claim the overtime deduction?
No. The overtime premium deduction is an above-the-line adjustment on Schedule 1-A — you can take the standard deduction and still claim it in full.
