Construction schedules concentrate work: weather windows, project deadlines, and trade sequencing routinely produce 45–55 hour weeks in season. A W-2 tradesperson at $30/hour with 350 annual overtime hours earns about $15,750 in time-and-a-half wages — and the premium third, roughly $5,250, is now deductible from federal taxable income, up to $12,500 ($25,000 joint).
The industry catch is classification. Construction leads the economy in 1099 labor, and independent contractors have no FLSA employer, no required overtime, and no overtime deduction. That line isn't always drawn correctly — a "1099 contractor" who works one crew's schedule with the company's tools may be a misclassified employee — but the deduction follows your actual tax paperwork. W-2 workers qualify; 1099 workers don't, regardless of hours.
Prevailing-wage and Davis-Bacon jobs add a wrinkle worth money: fringe amounts paid as cash wages belong in the FLSA regular rate, raising the overtime premium owed and deductible. Union scale plus supplemental checks makes the qualified number genuinely non-obvious — the free review sorts it out from your W-2 and stubs before anything is filed.
