Our last article provided a high-level overview of several provisions of the One Big Beautiful Big that are likely to impact the construction industry. In this article, we’ll focus on four of the most noteworthy elements of the new tax law as it pertains to construction companies: the “no tax on overtime” provision, 100% bonus depreciation, expansion of the Section 179 deduction, and immediate expensing for domestic research and development costs.
“No Tax on Overtime”
The OBBBA creates a temporary deduction of up to $12,500 ($25,000 for joint returns) for individuals who receive qualified overtime compensation (as defined by the Fair Labor Standards Act), available for tax years 2025 through 2028. The deduction applies only to the premium portion of overtime pay (the amount paid in excess of the taxpayer’s regular rate of pay) and begins to phase out when the taxpayer’s modified adjusted gross income (MAGI) exceeds $150,000 ($300,000 for joint filers). Note that the deduction applies only to federally required overtime under FLSA (Section 7), not to enhanced state overtime rules or those negotiated under collective bargaining agreements.
Impact on Construction Companies: The new deduction may incentivize construction employees to work more overtime hours. Employers will need to track and separately report qualified overtime compensation on employee W-2s.
100% Bonus Depreciation Restored
The OBBBA permanently restores 100% bonus depreciation for qualified property placed in service as of January 19, 2025, reversing the planned phase-down of this federal tax deduction.
Impact on Construction Companies: The restoration of 100% bonus depreciation means that construction companies purchasing qualifying equipment or machinery can now fully deduct these purchases in the year they are placed into service. This reduces taxable income and frees up capital for other purposes.
Section 179 Expansion
Similar to 100% bonus depreciation, the Section 179 deduction enables businesses to deduct the full cost of qualifying equipment in the year it is placed into service. The OBBBA increases the Section 179 expensing limit to $2.5 million, reduced by the amount by which the cost of qualifying property exceeds $4 million (new phasedown threshold).
Impact on Construction Companies: The increased limit for the Section 179 deduction allows construction companies to deduct a greater portion of their qualifying purchases immediately.
Immediate R&D Deductions Restored
U.S. research and development expenditures, previously required to be amortized over five years, can now be deducted in the year paid. Small businesses averaging $31 million or less in annual gross receipts for the prior three tax periods may elect to apply the change retroactively for tax years beginning after December 31, 2021. All businesses that made domestic R&D expenditures between 2022 and 2024 may elect to accelerate the remaining deductions for those expenditures over one or two years. Unlike domestic expenditures, foreign R&D costs continue to require a 15‑year amortization under Section 174.
Impact on Construction Companies: The restoration of immediate R&D deductions will allow construction companies to immediately deduct expenses related to domestic research and development, such as experimenting with new building techniques, technologies, design processes, and more.
