A new tax opportunity is opening doors for construction firms, but experts warn that execution and documentation will determine whether companies fully benefit.

Following the passage of the One Big Beautiful Bill Act, contractors can once again take advantage of 100% bonus depreciation. However, according to Chris Coleman of RubinBrown, the policy alone is not enough to guarantee success.
Construction companies are already revisiting capital spending plans, particularly for equipment, fleet upgrades and facility improvements. These investments can now deliver immediate tax relief instead of being spread across multiple years.
But the benefits come with added complexity, especially as the Internal Revenue Service faces staffing shortages and slower response times.
The reinstatement of full bonus depreciation reverses earlier limits set under the Tax Cuts and Jobs Act, which had gradually reduced first-year deductions.
For construction firms, this change significantly improves short-term cash flow. Instead of spreading deductions over time, companies can now immediately write off qualifying capital investments.
This shift is expected to influence purchasing behavior across the industry, encouraging firms to move forward with previously delayed investments. It also plays a critical role in financial forecasting, affecting pricing strategies, capital allocation and debt planning.
Despite the financial upside, companies face a more challenging regulatory environment.
The IRS is currently dealing with reduced staffing and increased workloads, leading to delays in issuing guidance and resolving tax-related questions. This creates uncertainty for contractors attempting to navigate new rules.
As a result, construction firms must take greater responsibility for ensuring their tax positions are accurate and well-supported. Poor documentation or inconsistencies could lead to delays, audits or additional scrutiny.
One of the most valuable strategies under 100% bonus depreciation is cost segregation — a method that breaks down building components into shorter depreciation categories.
This approach allows firms to accelerate deductions for items like lighting, parking areas and site improvements. Under the current rules, these components may qualify for immediate expensing, significantly boosting cash flow.
However, the stakes are higher. Improper classification or weak documentation can trigger reviews or reclassification during audits, particularly in today’s constrained IRS environment.
Beyond tax strategy, firms are being urged to improve internal processes.
Accurate fixed-asset records are essential. Outdated or incorrect entries — often referred to as “ghost assets” — can complicate filings and raise red flags during reviews.
Companies should also revisit internal controls, including capitalization thresholds, asset tracking systems and documentation practices. Ensuring clarity around when assets are placed in service and how costs are recorded can reduce risk and streamline compliance.
The return of 100% bonus depreciation comes at a time when construction firms are balancing rising material costs, tighter financing conditions and ongoing labor challenges. In this environment, tax strategy has become a critical lever for maintaining profitability and liquidity.
For many contractors, the ability to immediately expense large capital investments could influence not only purchasing decisions but also broader business strategies, including expansion plans and equipment modernization.

However, the current IRS environment adds a layer of risk. With fewer resources available for guidance and review, companies must operate with greater precision and self-reliance. This shift effectively transfers more compliance responsibility onto taxpayers.
Additionally, the growing complexity of construction projects — particularly in sectors like infrastructure, manufacturing and multifamily housing — makes accurate asset classification more important than ever. As projects become more sophisticated, so too must the accounting practices that support them.
Looking ahead, firms that integrate tax planning with operational discipline will be best positioned to capitalize on the opportunity. Those that fail to align documentation, processes and strategy may find that the benefits of bonus depreciation are offset by delays, disputes or compliance challenges.
Ultimately, while the policy provides a powerful financial tool, its real value will depend on how effectively construction companies execute behind the scenes.
