In the modern global economy, the ability of nations to attract private capital is the primary engine of innovation, wage growth, and sustained prosperity. As governments navigate a landscape defined by high inflation and shifting supply chains, a crucial tax policy tool has emerged at the center of the debate: capital allowances. By allowing businesses to recover the costs of physical assets—such as machinery, technology, and manufacturing facilities—through immediate tax deductions, nations can significantly lower the barrier to investment.
However, a new report from the Tax Foundation highlights a troubling trend: while many developed nations have recognized the power of these incentives, they continue to rely on temporary measures. As policymakers in major economies like Canada, Germany, and the United States look toward future growth, the consensus among economists is clear: for capital allowances to truly move the needle on productivity, they must be made permanent.
The Economics of Investment: Why Timing Matters
At the heart of the business investment decision is a simple calculation: is the projected profitability of a new machine or factory worth the upfront capital expenditure? Taxes play a decisive role in this calculus. When a business invests in a physical asset, the "cost" of that investment is not merely the sticker price of the equipment; it is also the tax treatment of that expenditure over time.
Under standard accounting rules—often referred to as depreciation schedules—businesses are required to spread the cost of an asset over many years, sometimes decades. This approach is economically inefficient. In an inflationary environment, the value of a dollar deducted ten years from now is significantly less than a dollar deducted today. Consequently, inflation erodes the value of these deductions, effectively increasing the tax burden on new investment and discouraging firms from modernizing their facilities.
Conversely, "full expensing"—the ability to deduct the entire cost of an investment in the year it is made—removes this distortion. It ensures that the tax system remains neutral, preventing inflation from acting as a hidden tax on capital formation. When businesses can recover costs immediately, they are incentivized to invest more aggressively, which in turn boosts worker productivity, increases output, and ultimately drives higher wages.
A Chronology of Policy Shifts: From Temporary Relief to Long-Term Vision
The history of capital allowances in the OECD over the past decade is a rollercoaster of legislative action and expiration.
2017–2022: The Golden Era of Expensing
Following the 2017 Tax Cuts and Jobs Act in the United States, which introduced bonus depreciation, and similar moves in countries like Chile and the UK, global capital allowances reached a high-water mark. In 2022, nations like Chile, Estonia, and Latvia offered full expensing, while others provided robust deductions for equipment. During this window, nations that embraced these reforms saw a marked improvement in their standing on the International Tax Competitiveness Index (ITCI).
2023–2024: The "Sunset" Problem
As temporary policies began to expire, the global average for cost recovery dropped sharply. In 2022, OECD countries allowed businesses to deduct 71.2 percent of investment costs; by 2024, this figure had fallen to 68.8 percent. The result was an artificial cooling of investment as businesses faced the looming expiration of tax-advantaged status for new projects.
2025–2026: A Partial Rebound
Recognizing the economic damage caused by expiring incentives, several nations have moved to stabilize their tax codes. The United States made full expensing permanent in 2025, a landmark move expected to raise long-term GDP by 0.6 percent. Meanwhile, Germany’s Growth Opportunities Act and Canada’s reinstatement of accelerated depreciation schedules signal a growing recognition that capital allowances are not just a stimulus tool, but a prerequisite for competitiveness.
Supporting Data: The Cost of Uncertainty
The quantitative impact of these policies is staggering. According to OECD data, in 2025, the average developed nation allowed businesses to recover only 70.1 percent of their investment costs. When inflation is factored in—with the OECD inflation rate hovering at 3.6 percent—the actual recovery rate is significantly lower.
An increase in inflation from 2 percent to 3.6 percent results in a reduction of deductible costs by up to 4 percentage points. This means that, on average, roughly one-third of the cost of a capital investment is essentially "taxed away" due to the inability of current depreciation schedules to account for the time value of money.
The International Tax Competitiveness Index provides the best empirical evidence of these impacts. For example:
- The United States: By embracing robust capital allowances, the U.S. rose 15 places in the ITCI rankings over the last 12 years.
- Canada: Improved capital allowances helped Canada climb eight places, moving from 25th to 13th in the global rankings.
- Chile: Conversely, as Chile phased out its full-expensing regime, its corporate tax rank dropped nine places, demonstrating that progress in tax policy is not guaranteed and can be easily reversed.
Official Responses and Regional Outlooks
Different nations have adopted distinct strategies for managing capital allowances, reflecting their unique domestic political pressures.
- Canada: Canada’s current policy environment is at a crossroads. While the government reinstated phased-out deductions for 2025–2029, the lack of a permanent structure creates a "cliff" for businesses. With new legislation in the Senate aiming to expand expensing to manufacturing, Canada has a golden opportunity to move beyond temporary patches and lock in long-term growth.
- Germany: The Growth Opportunities Act was a major step forward, extending accelerated depreciation for machinery into 2027. However, like its North American counterparts, Germany’s approach remains iterative rather than foundational.
- The United Kingdom: Perhaps the most decisive actor has been the UK, which transitioned from a temporary "super-deduction" to a permanent full-expensing regime. Chancellor Jeremy Hunt’s commitment to permanence is estimated to boost long-run GDP by nearly 1 percent, providing a roadmap for other G7 nations to follow.
- New Zealand: After a period of policy flip-flopping, the 2025 budget introduced a 20 percent immediate deduction for new assets. The absence of an end date is a positive signal, suggesting a shift toward more permanent, structural support for capital investment.
Implications: The Necessity of Permanence
The core finding of recent economic analysis is that temporary tax incentives are a suboptimal tool for long-term planning. When a policy is scheduled to expire, businesses often simply "pull forward" investments that they would have made anyway, rather than creating new, additional capital. This creates a "spike" in investment activity followed by a sharp drop-off, leading to volatility in economic output.
If Canada and Germany—two pillars of the global economy—fail to solidify their capital allowance regimes, they risk falling behind. The current patchwork of temporary extensions creates uncertainty, forces firms to waste resources on tax planning rather than R&D, and discourages the long-cycle investments required to transition to a greener, more digital economy.
A Roadmap for Future Reform
To foster a resilient and competitive business climate, policymakers should adopt three core principles:
- Permanence: Move away from "sunset" clauses. Certainty is the most important factor in corporate capital budgeting.
- Neutrality: Ensure that the tax code does not discriminate against capital investment by allowing for full, immediate expensing of equipment and machinery.
- Inflation Adjustment: For long-term assets where immediate expensing may not be feasible, implement indexation to ensure that depreciation allowances keep pace with the real-world value of money.
In conclusion, the global race for private investment is intensifying. As nations compete to host the next generation of manufacturing and technological infrastructure, the tax treatment of investment will be the deciding factor. By making capital allowances a permanent feature of their tax codes, developed nations can transform their economic outlooks, ensuring that the next decade is defined by growth, innovation, and enhanced productivity for all.
