Police overtime is structural: court time lands on days off, shifts hold over, details and events demand coverage. Departments routinely see officers earn $15,000–$30,000 in annual overtime wages. Under the 2025 law, the premium third of those time-and-a-half wages is deductible — up to $12,500 ($25,000 joint).
The law-enforcement wrinkle is FLSA §207(k): public-safety agencies may use extended work periods (up to 28 days) instead of the standard 40-hour week, which changes where federally-required overtime begins. Overtime your department pays because of contract or state rules before the FLSA threshold isn't "qualified" — only the federally-required premium counts. Officers whose contracts are more generous than the FLSA need the qualified number separated out, which is precisely what pay stubs don't do.
Off-duty security details paid by third parties through the department generally follow the same analysis as regular wages, while genuinely independent 1099 detail work falls outside the deduction. If your 2025 return skipped the deduction — most did, since the qualified amount appears nowhere obvious — an amendment recovers it.
