Construction and Trade Workers: How No Tax on Overtime Applies to Prevailing Wage and Job Sites

Construction and trade workers can claim the federal OBBBA overtime tax deduction. Whether working on private commercial sites, residential jobs, or public projects subject to prevailing wage laws, hourly tradespeople can deduct the FLSA-required overtime premium on federal Schedule 1-A.

Key takeaways for trade workers

• The overtime deduction applies to the FLSA-required half-time premium based on your cash regular rate.
• On Davis-Bacon prevailing wage jobs, employer fringe benefit payments do not inflate the deductible overtime premium.
• Travel time pay between job sites qualifies as hours worked toward your weekly 40-hour threshold.
• Weather makeup days count toward overtime only if total weekly hours exceed 40.

Prevailing wage jobs and the Davis-Bacon Act

Electricians, plumbers, carpenters, and ironworkers on government-funded projects work under the Davis-Bacon Act or state prevailing wage statutes. For federal wage determinations, see DOL Davis-Bacon wage guidelines and DOL overtime rules.

Prevailing wage determinations specify two separate compensation components: a basic hourly cash rate and a mandatory fringe benefit amount. Under federal law, overtime calculations are performed exclusively on the basic hourly cash rate, unless fringe benefits are paid out in cash without an approved plan.

For example, if the prevailing wage is $40 cash plus $15 in bona fide fringe benefits, the regular rate for overtime is $40 per hour. The deductible half-time premium is $20 per hour. The $15 fringe contribution is excluded from the overtime base. Learn how to calculate these amounts in our overtime calculation guide.

If a contractor contributes the $15 per hour into union pension and medical trusts, those contributions are exempt from FICA and income tax, but they cannot be used to inflate the overtime deduction. The deduction strictly mirrors the cash regular rate.

Travel time, staging areas, and portal-to-portal rules

Under the Portal-to-Portal Act, travel time rules determine which hours count toward the 40-hour weekly overtime threshold:

• Ordinary home-to-work commute: Travel from your home to the first job site of the day is not compensable hours worked.
• Job site to job site travel: Travel between different construction sites during the workday is compensable working time.
• Hauling equipment or materials: Driving a company vehicle carrying materials or crew members from a central yard to a job site is compensable time that counts toward overtime.

When site-to-site travel pushes total weekly hours past 40, all excess hours must be compensated at time-and-a-half, generating qualified overtime compensation for Schedule 1-A.

Inclement weather, makeup days, and weekend work

Construction contracts often include weekend makeup days after rain delays. A weekend shift paid at regular wage rates does not generate qualified overtime unless your total hours worked for the 7-day workweek exceed 40. See our detailed breakdown in the weekend and holiday pay guide.

If a rain delay limits you to 24 hours Monday through Thursday, and you work 8 hours on Saturday, your weekly total is 32 hours. No FLSA overtime is required, so no OBBBA deduction is created, even if your union contract pays a premium for Saturday work. The federal tax deduction follows the statutory FLSA threshold, not contract naming conventions.

Verifying Form W-2 Box 12 code TT

Trade workers who change employers frequently or work through union hiring halls receive multiple W-2 forms. Each employer reports qualifying overtime in Box 12 code TT. Review our guide on handling multiple W-2s for overtime.

You add together the Box 12 code TT amounts from all W-2s when completing Schedule 1-A. The statutory caps ($12,500 single, $25,000 married) apply per tax return, not per employer. If one contractor reports $8,000 and another reports $6,000, your combined deduction for a single filer is capped at $12,500.

Frequently asked questions

Can independent 1099 subcontractors claim the overtime deduction?

No. The overtime deduction under IRC section 225 applies only to employees eligible for FLSA overtime pay. Genuine independent contractors do not receive FLSA overtime and cannot claim the deduction.

Does union scale double time qualify for the deduction?

Only the FLSA-mandated one-half regular rate premium qualifies. The contractual portion beyond time-and-a-half does not qualify as deductible overtime compensation.

What if my employer pays cash in lieu of fringe benefits?

If an employer pays the fringe benefit requirement in cash on your paycheck rather than contributing to bona fide benefit plans, that cash must generally be included in the regular rate, increasing your deductible overtime premium.

Can I claim both standard deduction and construction overtime?

Yes. The OBBBA overtime deduction on Schedule 1-A stacks with the standard deduction on Form 1040 line 13.
