Tax Credits for Construction Companies

Construction runs on thin margins, and most contractors know tax credits exist. What they don’t always know is how much they’re leaving behind. The programs covered here aren’t designed for unusual operations. They apply to activities you’re likely already doing: solving technical problems on job sites, hiring workers, building energy-efficient structures, buying equipment. What separates the contractors who claim them from those who don’t is documentation, timing and knowing where to look.

Your Job Site Problem-Solving Probably Qualifies for R&D Credits

Most construction firms don’t think of themselves as R&D operations. That assumption costs them money every year.

The federal R&D tax credit applies to companies that develop new processes, design innovative construction methods or work through genuine technical challenges on specific projects. When your team figures out how to retrofit an older building’s HVAC system within strict space constraints, that qualifies. When you develop a new approach to foundation work for difficult soil conditions, that counts. When estimators and engineers collaborate to value-engineer a project, those labor hours are potentially creditable.

You don’t need a lab or patents. You need documentation showing your team attempted to develop or improve a process, dealt with real technical uncertainty and followed a systematic approach. Custom fabrication, BIM modeling that resolves design problems and preconstruction planning that addresses site-specific challenges all fit. The credit covers wages, supplies and contractor expenses tied to qualified research activity, and most contractors who look closely find they’ve been leaving it unclaimed for years. The IRS research credit guidance lays out what qualifies and what records you need.

Section 179D Is Worth Real Money, and the Clock Is Running

For contractors doing commercial work, Section 179D has become one of the more significant incentives in the tax code. It’s also about to get harder to access.

The inflation-adjusted deduction for 2025 reaches up to $5.81 per square foot for projects meeting prevailing wage and apprenticeship requirements, according to the Department of Energy. Projects that don’t meet those labor requirements qualify for a much narrower range, between $0.58 and $1.16 per square foot. That gap is large enough to influence how you staff and document a project before it breaks ground.

Contractors working on government-owned buildings have a distinct advantage here. Because government entities pay no federal income tax, they can allocate the 179D deduction to the designer or contractor primarily responsible for the energy-efficient improvements. Schools, municipal facilities, courthouses and fire stations all qualify. If you’re doing that work, the deduction can be yours. Under current rules, projects generally must demonstrate at least 25% energy-cost savings compared to applicable ASHRAE reference standards, with larger deductions available as savings increase.

The urgency: under the OBBBA, Section 179D terminates for any project where construction begins after June 30, 2026. That date is not theoretical. Projects currently in design or early estimating need to confirm their construction start timeline against that cutoff. Miss it and there’s no alternative. This is worth a conversation with your tax advisor now, not at year-end.

WOTC Expired, But Don’t Stop Screening

The Work Opportunity Tax Credit lapsed December 31, 2025. As of mid-2026 it cannot be claimed for new hires. That’s the honest answer.

The practical answer is different. Congress has reauthorized WOTC repeatedly since 1996, and reauthorization could include retroactive provisions covering hires made during the gap. Many state workforce agencies and WOTC administrators continue accepting Form 8850 submissions during the hiatus and holding them pending congressional action. Contractors who keep screening new hires and submitting Form 8850 within 28 days of each hire’s start date may be positioned to claim credits immediately if the program is reinstated. Those who stop the process will have no recourse. The paperwork takes minutes. The potential value per eligible hire reached up to $9,600 for certain veteran hires and $2,400 for most other targeted groups. It’s worth maintaining the habit.

Equipment Purchases Now Come with Full First-Year Expensing

The OBBBA permanently restored 100% bonus depreciation for qualified property acquired and placed in service after January 19, 2025. The phase-down that reduced the deduction to 60% in 2024 and was scheduled to eliminate it entirely by 2027 is gone. For construction companies making significant equipment investments, that means the full cost of a qualifying crane, excavator or fleet vehicle can be deducted in the year of purchase.

Section 179 was also expanded. The deduction limit rose to $2.5 million for 2025, up from $1.25 million under prior law. Both figures adjust for inflation going forward. The two provisions work differently and the right approach depends on your tax position, which is worth modeling before you finalize any major capital decision. Our analysis of OBBBA’s bonus depreciation rules covers how they interact for capital-intensive businesses.

Credits Don’t Capture Themselves

The contractors who consistently claim these incentives aren’t doing more work than anyone else. They’ve built the tracking into their operations: documenting R&D activity as it happens, maintaining WOTC screening during the hiatus, confirming 179D project start dates before the June 30 cutoff and timing equipment purchases with year-end tax position in mind.
