Construction and the building trades log more overtime hours per worker than any other major industry in the U.S. Project deadlines, weather windows, and chronic skilled-labor shortages mean 50- and 60-hour weeks during busy season are normal. The new federal "No Tax on Overtime" deduction under the One Big Beautiful Bill Act was effectively written for workers like you — most union and non-union W-2 trades workers will see real federal tax savings at filing time.
This is the no-fluff guide. It tells you who qualifies, who doesn't, what you'll actually save with worked examples for the most common trades, and how union prevailing wage fits in. If you just want to run your own numbers, the free calculator handles all the math.
Who Qualifies, Who Doesn't
The OBBBA deduction is tied to the federal Fair Labor Standards Act (FLSA), which only covers W-2 employees who exceed 40 hours per workweek. That single fact determines almost every eligibility question in construction.
| Your situation | Qualifies? |
|---|---|
| W-2 employee of a GC, sub, or trade contractor | Yes |
| Union hall member paid W-2 through the contractor | Yes |
| Apprentice paid W-2 (any year of apprenticeship) | Yes |
| Davis-Bacon / prevailing wage worker paid W-2 | Yes |
| 1099 independent subcontractor | No |
| Owner-operator / self-employed contractor | No |
| Salaried project manager / superintendent (FLSA exempt) | No |
| Filing Married Filing Separately (MFS) | No |
How Much Trades Workers Save: Four Worked Examples
Real numbers for four common trades situations. All assume single filer, 2025 federal brackets. Most union workers in major metros and most equipment operators hit numbers that push them into the 22% or 24% federal bracket.
$32/hour W-2 with a mid-size residential GC. Works 50-hour weeks from spring through fall, slower 36-hour weeks December–February. Total FLSA OT for the year: 400 hours.
$48/hour base prevailing wage (plus fringe in cash). Works 600 FLSA OT hours during peak construction season on a large commercial build. Single filer.
$42/hour W-2 base rate on state highway projects. 500 FLSA OT hours during night work and weekend lane closures. Single filer, MAGI ~$95K.
$22/hour W-2 with a remodeling contractor. 300 FLSA OT hours during busy season (April–October). Single filer, MAGI ~$55K.
When you hit the cap
The $12,500 single ($25,000 joint) cap is on the qualified premium amount, not on the tax savings. You hit the cap when your regular rate × 0.5 × annual FLSA hours > $12,500. Quick reference table for single filers:
| Regular rate | FLSA hours to cap | Hits cap? |
|---|---|---|
| $25/hr | 1,000 hrs | Rare |
| $35/hr | 714 hrs | Heavy OT seasons |
| $45/hr | 556 hrs | Common for union |
| $55/hr | 454 hrs | Common for union |
| $65/hr | 385 hrs | Common for union |
| $75/hr | 333 hrs | Easy to hit |
Union members earning $45+/hour on prevailing wage jobs typically hit the cap with 500–600 annual FLSA hours — fewer hours if you're in a higher bracket. Married Filing Jointly couples have a $25,000 combined cap (not per spouse), and a single trade worker with a non-working spouse can use the joint cap by filing jointly.

Open the CalculatorSeasonal Overtime: Adding Up Hours Across the Year
Construction overtime isn't steady — it's bursty. Snowed-out weeks in January contribute nothing. May through October you might pull 15 FLSA OT hours every single week. The deduction counts your annual total, so partial-year heavy weeks fully count. You don't need OT every week to qualify.
The pattern above represents a typical Northern-state outdoor crew: 7 busy months at ~15 OT hrs/week (≈60–65 hrs/month), 5 slow months at low or zero OT. The annual total comes out to ~445 FLSA hours — enough to push a $40/hour union carpenter to a $8,900 qualified premium ($40 × 0.5 × 445), worth roughly $1,960 in federal savings at the 22% bracket.
Track every week. Even a single 44-hour week in February contributes 4 FLSA OT hours to your annual total. Pay stubs and certified payroll records (if you're on Davis-Bacon jobs) are excellent documentation.
Union Workers: Prevailing Wage and CBA Rules
The OBBBA deduction works the same way for union and non-union workers, but a couple of union-specific points are worth clarifying.
Your "regular rate" is the base wage
For the OBBBA formula, use your prevailing wage base rate — the cash wage component shown on your certified payroll, not the total prevailing wage that includes fringe benefits. If your Davis-Bacon determination shows the base as $45/hour with $18/hour fringe (total $63), the federal premium calculation uses $45 × 0.5 × FLSA OT hours. Fringe paid in cash counts toward total wages but isn't part of the FLSA regular rate.
CBA daily-OT rules still need FLSA weekly check
Some collective bargaining agreements pay overtime after 8 hours in a day or after Saturday hours regardless of weekly total. CBA-required overtime doesn't change FLSA — only hours over 40 per week qualify for the OBBBA deduction. Your union pay stub may show "OT" hours that don't all count federally. Look at your weekly totals: only hours over 40/week qualify.
Union W-2 qualifies fully
Union hall members paid W-2 through signatory contractors qualify exactly like any other W-2 worker. Your union dues, health-and-welfare contributions, and pension contributions don't affect eligibility. The deduction applies to the half-time premium on your hourly wages over 40/week.
Working for Multiple Contractors in One Year
Construction is project-based. It's normal to work for 2, 3, or even 5 different contractors during one tax year. Two rules to know:
- FLSA hours are calculated separately per employer per workweek. Each employer determines your OT based on their own 40-hour workweek with you. Working 30 hours at one contractor and 20 hours at another in the same week generates zero FLSA overtime — because neither employer crossed 40 hours with you individually.
- The deduction cap is per return, not per employer. Add up FLSA hours and premium from all W-2 jobs across the year, combine on a single Schedule 1-A, and apply the $12,500 single (or $25,000 joint) cap to the total.
W-2 and Filing: What You'll Need
For tax year 2025, employer reporting in Box 14 was voluntary under IRS Notice 2025-62. Many construction employers reported qualified overtime with labels like "QUAL OT", "OBBBTT", or "FLSA OT"; many didn't. If your Box 14 shows the amount, copy it to Schedule 1-A of Form 1040.
If your Box 14 is blank, use IRS Notice 2025-69's calculation methods:
- Divide-by-3 method: Take total time-and-a-half overtime pay shown on your year-end pay summary and divide by 3. That gives you the premium portion. (For example: $19,200 total OT pay ÷ 3 = $6,400 premium.)
- Direct calculation: Regular rate × 0.5 × annual FLSA OT hours.
Davis-Bacon workers have an advantage here: certified payroll records (Form WH-347) document weekly hours and pay rates clearly, making the calculation simple. Keep your stubs and certified payroll for at least 3 years — the IRS standard audit window.
Starting tax year 2026, separate W-2 reporting becomes mandatory. The IRS has signaled this will be a new code under Box 12. See our W-2 guide for full details.
Frequently Asked Questions
I'm a 1099 subcontractor — do I qualify?
No. The OBBBA overtime deduction is tied to FLSA-required overtime, which only applies to W-2 employees. If you receive a 1099-NEC at year-end instead of a W-2, you are self-employed in the IRS's view and do not qualify — even if you actually work long hours on the job site.
Some contractors who are technically classified as 1099 may actually be misclassified W-2 employees under FLSA tests; consult a tax professional if you suspect that's your situation.
I work for two contractors in the same year — can I combine my OT hours?
Yes for the deduction total, but FLSA hours are calculated separately per employer per workweek. Sum the FLSA overtime hours from each W-2 job (each employer determines OT independently based on their own 40-hour workweek), then combine the resulting qualified premium amounts on a single Schedule 1-A. The $12,500 single / $25,000 joint cap is a return cap, not a per-employer cap.
What's the regular rate on a prevailing wage job?
Your prevailing wage base rate (the cash wage component) is your regular rate for the OBBBA formula. Fringe benefits paid in cash count toward total wages but aren't typically included in the FLSA regular rate.
If your CBA or Davis-Bacon determination shows the base rate as $45/hour with $18/hour fringe, the federal OBBBA premium calculation uses $45 × 0.5 × your FLSA OT hours.
Does Davis-Bacon prevailing wage work qualify?
Yes, as long as you are paid W-2 by your employer. Davis-Bacon is a federal wage standard, not a worker classification — it sets the minimum wage that must be paid on federally-funded construction projects.
If you're a W-2 employee on a Davis-Bacon job, your overtime premium qualifies for the OBBBA deduction. Your certified payroll records (WH-347) are excellent documentation for proving FLSA overtime hours.
I own my construction company — can I claim it on my own pay?
Owner-operators who pay themselves as 1099 or through S-corp distributions do not qualify — those aren't FLSA overtime wages. If you're an S-corp owner who pays yourself reasonable W-2 wages from your own company and your weekly W-2 hours exceed 40, technically you could qualify on the W-2 overtime portion, but most owners don't pay themselves overtime, and shareholders in their own S-corp can have FLSA exemption issues. Consult a CPA — this is a complicated edge case.
My Box 14 doesn't show overtime — what do I do?
Calculate it from your pay stubs. Per IRS Notice 2025-69, take your total time-and-a-half overtime pay shown on your year-end pay summary and divide by 3 — that's your qualified premium. Or multiply your regular hourly rate × 0.5 × annual FLSA overtime hours. Both methods produce the same answer.
Construction employers were not required to break out qualified overtime separately for tax year 2025 under IRS Notice 2025-62.
I work in California on commercial construction — anything different?
California requires daily overtime (over 8 hours per day), but the federal OBBBA deduction only covers hours over 40 per week. A 5×10 schedule generates both California daily OT and 10 FLSA OT hours per week. A 4×10 schedule generates California daily OT but zero FLSA hours.
California state income tax still applies to all overtime pay at rates up to 13.3% — the federal deduction reduces federal tax only. See our California guide for details.
Does the deduction affect workers' compensation premium calculations?
No. Workers' compensation premiums are calculated by your employer based on gross payroll and your job classification's experience modifier — completely separate from your federal income tax deduction. The OBBBA deduction affects your personal federal income tax liability at filing time; it doesn't change what your employer pays for workers' comp or any other payroll taxes.
How Much Do Taxes Take from Construction Overtime Pay?
Before OBBBA: a union carpenter at $35/hr in the 22% bracket lost $3.85 per overtime premium dollar to federal income tax. Under the OBBBA deduction, that $3.85 stays in your pocket — up to $12,500 per year (single) or $25,000 (married filing jointly). FICA (7.65%) still applies to all overtime wages.
