How construction companies can maximize OBBBA benefits in 2026

Author : Catherine Ronald | Published On : 26 Mar 2026

The One Big Beautiful Bill Act (OBBBA) introduces major tax advantages for construction companies in 2026, creating opportunities to significantly reduce tax liability and improve cash flow. Key provisions include the permanent return of 100% bonus depreciation, allowing businesses to fully expense qualifying equipment and assets in the year they are placed in service.

The legislation also makes the 20% qualified business income (QBI) deduction permanent, providing long-term tax savings for contractors operating as pass-through entities. Additionally, expanded residential construction accounting rules now allow more contractors to use the completed contract method (CCM), enabling them to defer income recognition and better manage cash flow.

Another critical opportunity lies in the Section 179D energy efficiency deduction, which remains available for qualifying projects that begin before June 30, 2026. After this deadline, the incentive will be eliminated, making early planning essential.

The increase in the SALT deduction cap and enhanced Section 179 expensing limits further strengthen tax-saving potential, particularly for businesses investing heavily in equipment and operating in high-tax states.

To fully capitalize on these benefits, construction companies must adopt proactive tax planning strategies, including timing equipment purchases, reviewing accounting methods, and ensuring proper documentation. Leveraging specialized construction accounting services can help businesses remain compliant while maximizing deductions and long-term profitability.
