For decades, the United States has sought a definitive policy lever to catalyze domestic investment, particularly within the manufacturing sector. From the American Recovery and Reinvestment Act of the Obama era to the landmark legislative suites of the Biden administration and the recent One Big Beautiful Bill Act of 2025 (OBBBA), federal policy has been defined by a singular goal: incentivizing the physical and intellectual expansion of the American economy.
At the heart of these efforts lies a technical but profoundly consequential mechanism: cost recovery. By allowing businesses to deduct investment expenses from their tax returns, the government alters the calculus of risk and reward. When a company can write off the cost of a new factory or a fleet of machines more quickly, the internal rate of return (IRR) on that project rises, often turning a marginal, unviable venture into a cornerstone of economic growth.
The Mechanics of Investment: Why Cost Recovery Matters
At its most fundamental level, economic growth is the product of three primary inputs: labor, capital, and total factor productivity. While innovation—the "how" of production—is vital, it is capital deepening that allows workers to be more productive. A farmer with a modern combine harvester, a steelworker with an automated furnace, and a data scientist with a high-performance computing cluster are all inherently more productive than their predecessors, not necessarily because they work harder, but because they are better equipped.
Tax policy influences the speed of this technological adoption. When the tax code requires businesses to spread the cost of an asset over decades—a process known as depreciation—it imposes a "tax penalty." A dollar of tax savings today is worth significantly more than a dollar of tax savings a decade from now due to the time value of money. Full expensing—the ability to deduct the entire cost of an investment in the year it occurs—eliminates this penalty, neutralizing the tax code’s bias against capital-intensive projects.
A Chronology of Policy Evolution
The debate over cost recovery has spanned several administrations, reflecting shifting priorities in industrial policy:
- The Early 2000s: Congress first introduced 30 percent bonus depreciation in 2002 to stimulate a sluggish economy. This marked the beginning of a cycle of temporary expansions, lapses, and renewals.
- The 2017 Tax Cuts and Jobs Act (TCJA): This legislation provided a significant boost, raising bonus depreciation to 100 percent for several years. However, it also introduced controversial changes, such as the mandatory amortization of domestic R&D, which forced companies to spread these costs over five years rather than expensing them immediately.
- The 2022 Legislative Suite: The CHIPS and Science Act and the Inflation Reduction Act targeted specific sectors, but left broader cost recovery issues largely unaddressed.
- The One Big Beautiful Bill Act of 2025 (OBBBA): This act represents the most recent evolution, restoring 100 percent bonus depreciation permanently and reintroducing full expensing for domestic R&D. Crucially, it also introduced a temporary expensing provision for "qualified production property," aimed specifically at manufacturing structures.
Analyzing the Impact: 15 Case Studies
To understand how these policies translate into real-world business decisions, the Tax Foundation analyzed 15 hypothetical, yet representative, investment projects across four sectors: Energy, Manufacturing, Technology, and Services.
Sector Analysis: Energy and Infrastructure
In the energy sector, including natural gas plants and pipelines, the findings were stark. For a $571.8 million natural gas power plant, full expensing for equipment raised the IRR by over 1 percentage point, moving the project from unviable to viable. Because these projects often involve long construction timelines, the transition to a cash-flow-based accounting system—rather than a "placed-in-service" rule—proved vital to maintaining project feasibility.
Sector Analysis: Manufacturing
Manufacturing projects, such as steel minimills and aerospace factory expansions, highlighted the limitations of current law. The OBBBA’s manufacturing structures provision is a welcome development, but its temporary nature—limited to construction starting before 2029—creates uncertainty. For a $250 million gas turbine factory, the difference between baseline depreciation and full expensing was nearly 2 percentage points, illustrating that even small tax changes can determine whether a project moves from the drawing board to the construction site.
Sector Analysis: Technology and R&D
In technology, the impact of R&D expensing is paramount. For a $5.1 billion warehouse robotics R&D program, full expensing of research costs was the single most important driver of viability. However, the contrast between domestic and foreign R&D treatment remains a friction point. The OBBBA retains 15-year amortization for foreign R&D, which creates a competitive disadvantage for American firms operating global supply chains, as they often rely on integrated R&D teams across multiple borders.
Sector Analysis: Services
Service-based projects, such as apartment buildings and supermarkets, are highly sensitive to structure depreciation. Because these projects have a high ratio of structural costs, they suffer the most under 39-year depreciation schedules. The data showed that extending full expensing to all commercial structures could be a potent tool for addressing housing supply shortages, as it would directly improve the economics of multi-family residential construction.
Official Perspectives and Industry Response
The business community has largely lauded the OBBBA’s progress but remains cautious regarding the "loss-position" problem. Even when a tax code allows for full expensing, companies that are not yet profitable—a common scenario for startups or companies undergoing massive capital pivots—cannot utilize the deductions.
Industry advocates suggest two paths forward:
- Transferability: Similar to the mechanism in the Inflation Reduction Act, allowing firms to sell their tax deductions to other profitable entities would unlock billions in capital.
- Safe Harbor Leasing: Historically used in the 1980s, this would allow firms to "lease" their tax assets to companies with current tax liability, ensuring that the incentive is felt immediately regardless of the company’s current profit status.
Implications for Future Policy
The evidence suggests that while the OBBBA has captured roughly half of the potential economic gains from full expensing, the remaining half is held hostage by structural rigidities. To maximize the impact of American investment, policymakers face three clear imperatives:
1. Cementing Permanence: The temporary nature of the manufacturing structures provision discourages long-term planning. Projects like semiconductor fabs take years to permit and build; a tax window that closes in 2029 is functionally invisible to a project with a ten-year horizon.
2. Addressing Structural Bias: The tax code continues to penalize buildings more heavily than machines. Whether through full expensing or a "neutral cost recovery" system—where depreciation is adjusted for inflation—the government must stop punishing investments in physical space.
3. Modernizing the Standard: The current "placed-in-service" rules are an artifact of an older, slower economy. In an era where capital costs are incurred over years of planning and procurement, moving to a cash-flow-based accounting standard would ensure that the tax code reflects the reality of modern business finance.
Conclusion
The data confirms that cost recovery is one of the most powerful, non-discriminatory tools available to federal policymakers. It does not rely on "picking winners" in the way that industry-specific tax credits do; rather, it improves the economic viability of all capital-intensive projects.
While the One Big Beautiful Bill Act of 2025 has provided a significant tailwind for American manufacturing and R&D, the job is incomplete. By addressing the remaining barriers—specifically regarding structures, foreign R&D, and the loss-position problem—the United States can further reduce the tax-induced drag on investment. As the global economy becomes increasingly competitive, the ability to turn "unviable" projects into reality will be the deciding factor in the next generation of American economic growth.
