The OBBB delivers sweeping, mostly taxpayer-friendly changes by locking in lower income tax rates, boosting standard deductions (especially for seniors), and expanding deductions for tips, overtime, and auto loan interest while also raising the SALT cap and enhancing estate and business tax breaks.
Most benefits are front-loaded through 2028, meaning individuals and businesses should act now to maximize opportunities before key provisions phase out or revert. Get with your tax professional to verify how the new changes affect you and your business.
Here is a breakdown of the top 10 tax changes for construction under the Big, Beautiful Bill.
1. 100% Bonus Depreciation Now Permanent – You can fully expense eligible equipment and property in the year of acquisition with retroactivity starting January 19, 2025.
2. Section 179 Expensing Increased – The deduction limit rises to $2.5M, phasing out when purchases exceed $4M.
3. Immediate Expensing for U.S. Production Property – Nonresidential property used in manufacturing qualifies for full depreciation if construction begins between January 20, 2025 and the end of 2028 and is placed in service by January 1, 2031 (awaiting additional IRS guidance).
4. Restore R&D Expense Deduction – Domestic research expenses are fully deductible in the year incurred; eligible small businesses may be able to amend 2022-2023 (and in some cases 2024) returns, with an election deadline of July 4, 2026.
5. Permanent 20% QBI Deduction – The pass-through business deduction is now indefinite, lowering effective top tax rates.
6. More Interest Deductions Allowed – The interest expense limit now uses EBITDA instead of EBIT, benefiting capital-heavy companies.

8. Accelerated Cutoff for Green Energy Credits – Energy-efficient building deductions (179D) and home credits (45L) now expire after mid-2026.
9. Expanded Revenue Deferral for Residential Projects – Larger developments including more than four units can now defer income recognition until project completion.
10. Temporary Overtime Deduction (2025–2028) – Workers may deduct up to $12,500 ($25,000 joint) for qualifying overtime pay, subject to income phase-outs.
