Introduction

The ongoing economic uncertainty from Russia’s war in Ukraine, post-pandemic economic recovery, supply chain disruptions, and rising interest rates have highlighted the importance of investment. Policymakers around the world are working to support critical infrastructure, transition to an environmentally sustainable economy, and gear their economic policies toward growth.

In 2019, private sector investment in OECD countries outpaced public investment by five to one. According to data from the International Monetary Fund (IMF), the average OECD country saw nearly $300 billion in private investment compared to $55 billion in public investment. Ensuring a stable environment for business investment will be critical in the coming years.[1]

Although sometimes overlooked in discussions about corporate taxation, capital cost recoveryCost recovery is the ability of businesses to recover (deduct) the costs of their investments. It plays an important role in defining a business’ tax base and can impact investment decisions. When businesses cannot fully deduct capital expenditures, they spend less on capital, which reduces worker’s productivity and wages.
plays an important role in defining a business’s corporate tax baseThe tax base is the total amount of income, property, assets, consumption, transactions, or other economic activity subject to taxation by a tax authority. A narrow tax base is non-neutral and inefficient. A broad tax base reduces tax administration costs and allows more revenue to be raised at lower rates.
and can impact these investment decisions—with far-reaching consequences. When businesses are not allowed to fully deduct capital expenditures in real terms, they make fewer capital investments, which also reduces worker productivity and wages.[2] Thus, businesses should be allowed to fully deduct their capital investments in real terms—either through full expensingFull expensing allows businesses to immediately deduct the full cost of certain investments in new or improved technology, equipment, or buildings. It alleviates a bias in the tax code and incentivizes companies to invest more, which, in the long run, raises worker productivity, boosts wages, and creates more jobs.
or neutral cost recovery.[3]

Capital cost recovery varies greatly across OECD countries, ranging from 100 percent in real terms in Estonia and Latvia to only 41.7 percent in Chile and 53 percent in New Zealand (covering industrial buildings, machinery, and intangibles). After years in which many OECD countries changed their capital allowance rules due to the pandemic, many of the temporary measures of accelerated depreciation ended or started phasing out in 2023.

On average, businesses in the OECD can recover 68.6 percent of the cost of capital investments in real terms. Investments in machinery enjoy the best treatment, with an OECD average of 85.3 percent, followed by intangibles (76.4 percent) and industrial buildings (48 percent). In 2000, businesses were able to recover on average 70.4 percent of capital investment costs in the OECD, followed by a gradual decline and then an increase beginning in 2018.

Inflationary pressures and high interest rates decrease the value of capital cost allowances and thus increase the cost of new investments. For consistency, this report assumes an inflation rate of 2 percent, but such a low inflation rate is rare in the current economy. Mexico and Israel are currently the only OECD countries to adjust capital allowances for inflation.

Since 2000, statutory corporate income tax rates have declined significantly across the world and in OECD countries.[4] However, as the average tax treatment of capital investments worsened for most of the last two decades, the benefits of lower statutory rates for investment and growth were partially offset. This broadening of tax bases through lower capital allowances is one of the reasons why corporate tax revenues had been growing or were stable around the world despite declining statutory rates.[5]

The Basics of Depreciation Schedules and Capital Allowances

Before exploring the data more closely, it is worth understanding some of the terminology used in this area of corporate taxation:

• Governments set depreciation schedules to define how businesses can deduct their capital investment costs from their revenues over several years.
• The amount of investment costs a business can deduct in a year is called a capital allowance.
• Full expensing allows businesses to deduct the full cost of a capital investment in the year of acquisition rather than following a multiyear depreciation schedule.
• Accelerated depreciation or bonus depreciationBonus depreciation allows firms to deduct a larger portion of certain “short-lived” investments in new or improved technology, equipment, or buildings in the first year. Allowing businesses to write off more investments partially alleviates a bias in the tax code and incentivizes companies to invest more, which, in the long run, raises worker productivity, boosts wages, and creates more jobs.
  increases capital allowances in earlier years and is often used to stimulate investment during economic downturns.
• Capital cost recovery rates reflect the net present value of capital allowances a business can deduct for a given capital investment over the full depreciation period.

Businesses determine their profits by subtracting costs (such as wages, raw materials, and equipment) from revenue. However, in most jurisdictions, capital investments are not treated like other costs that can be subtracted from revenue in the year that the money is spent. This introduces a bias toward short-term projects, with little or no capital investment.

Instead, depreciation schedules specify the life span of an asset—often derived from the economic life of an asset—and determine the number of years over which an asset must be written off. By the end of the depreciation period, the business would have deducted the initial dollar cost of the asset.[6] However, in most cases, depreciation schedules do not consider the time value of money (a normal return plus inflation).[7]

Depreciation schedules can be based on different methods, with straight-line depreciation and declining-balance depreciation the most common. The methods define how annual capital allowances are calculated. While the straight-line method depreciates an asset by an equal allowance each year, the declining-balance method bases the annual allowance on the remaining book value of the asset. (See the Appendix for example calculations.)

Such depreciation schedules define how much of capital investment costs a business can deduct in real terms. For instance, assume a machine costs $10,000 and is subject to a life span of 10 years. Under straight-line depreciation, a business could deduct $1,000 every year for 10 years. However, due to the time value of money, a deduction of $1,000 in later years is not as valuable in real terms as today’s deduction. If inflation is 2 percent and the required real return on investment is 5.5 percent, then at the end of the 10-year period, the value of that last deduction will be just $522 in today’s terms. In total, the business will only be able to deduct $7,379 instead of the full $10,000, just 73.8 percent of the total. This understates true business costs and inflates taxable profits, effectively taxing profits that do not exist.

This effect is exacerbated by longer depreciation schedules and higher inflation or higher interest rates. Lower capital allowances, and thus a higher cost of capital, can lead to a decline in business investment, reductions in the productivity of capital, and lower wages.[8]

Capital allowances can be expressed as a percentage of the net present value of investment costs that businesses can write off over the life of an asset—the so-called capital cost recovery rate. A 100 percent capital cost recovery rate represents a business’s ability to deduct the full cost of the investment (including a normal return plus inflation) over its life (e.g., through full expensing or neutral cost recovery). A capital cost recovery rate above 100 percent represents the possibility for businesses to deduct more than the full cost of an investment. The lower the capital cost recovery rate, the more a business’s taxable incomeTaxable income is the amount of income subject to tax, after deductions and exemptions. For both individuals and corporations, taxable income differs from—and is less than—gross income.
is inflated and the more its tax bill is overstated, making capital investment more expensive.

Capital Allowances and Economic Growth

Although sometimes overlooked as a more technical issue, capital allowances can have important economic impacts. Depending on their structure, they can either boost or slow investment which, in turn, impacts economic growth.

Lower Capital Allowances Lead to Slower Economic Growth

Any cost recovery system that does not allow the full write-off of an investment—full expensing—in the year the investment is made denies recovery of a part of that investment, inflates the taxable income, and increases the taxes paid by businesses.[9] Lower capital allowances increase the cost of capital, which leads to slower investment and a reduction of the capital stock, reducing productivity, employment, and wages.[10]

Prior research has found evidence that investment is sensitive to changes in the cost of capital. In a literature review, economists Kevin Hassett and R. Glenn Hubbard found “a consensus has emerged [among economists] that investment demand is sensitive to taxation.” In other words, as a result of either longer asset lives or a higher corporate income tax rate, the demand for capital decreases and levels of investment decline, reducing the growth in the capital stock.[11] A 2023 study finds that investment is also sensitive to inflation. In a scenario with a corporate tax rate of 22 percent, a depreciation rate of 25 percent, and an inflation rate of 2 percent, a one-percentage-point increase in inflation reduces the optimal investment level by 0.42 percent.[12] A reduction in the capital stock leads to lower wages for workers and slower economic growth.[13]

In recent years, more empirical results on such investment effects have emerged. A 2017 study by economists Eric Zwick and James Mahon shows that bonus depreciation implemented in the United States raised investment in eligible capital relative to ineligible capital by 10.4 percent between 2001 and 2004 and by 16.9 percent between 2008 and 2010. In addition, their findings showed that small firms are dramatically more sensitive to the policy change than large firms.[14]

A study conducted by economists Giorgia Maffini, Jing Xing, and Michael P. Devereux estimates the effect of accelerated depreciation allowances the UK introduced in 2004. Their results show that “the investment rate of qualifying companies increased 2.1-2.5 percentage points relative to those that did not qualify.”[15] Economists Yongzheng Liu and Jie Mao found that China’s switch from a production-based VAT to a consumption-based VAT—meaning there is now an investment tax creditA tax credit is a provision that reduces a taxpayer’s final tax bill, dollar-for-dollar. A tax credit differs from deductions and exemptions, which reduce taxable income, rather than the taxpayer’s tax bill directly.
—also had a positive effect on investment.[16]

Unequal Capital Allowances Create a Distortion among Different Investments in the Economy

It is also important to note that capital allowances can distort the relative costs of different investments and thus alter the mix of capital in an economy. A government could lengthen depreciation schedules for machinery, which would slow investment in machinery, harming the manufacturing industry. Likewise, if depreciation schedules are shortened, or if businesses are allowed expensing of machinery, this increase in capital allowances may spur more machinery investment relative to other investment in the country.

Looking at the average capital cost recovery rate in OECD countries by asset type, stark differences are evident. Businesses in the OECD are able to recover on average 85.3 percent of investment costs in machinery and 76.4 percent in intangibles, but only 48 percent for buildings.

Additionally, in high-inflation scenarios like the current one—where the OECD annual inflation was 6.9 percent in 2023—the investment amount businesses are able to recover is significantly diminished.[17] If inflation is 6.9 percent and the required real return on investment is 5.5 percent, then businesses in the OECD will be able to recover on average only 36.5 percent for buildings, 78.6 percent for machinery, and 67.6 percent for intangibles. Therefore, an increase in inflation from 2 percent to 6.9 percent reduces the amount of investment that can be recovered by up to 11.4 percentage points. But even relatively low rates of inflation can significantly reduce the values of deductions for long-term investments. Similarly, high interest rates reduce the value of deductions over time by increasing the required real return on investment.

Tax changes in the United States have given preferential tax treatment to certain assets over others, which has led to changes in the composition of investment. In 2003, the United States passed the Jobs and Growth Tax Relief Reconciliation Act of 2003 (JGTRRA). Part of this law allowed for partial expensing of certain capital equipment, increasing capital allowances and reducing the cost of other capital investments by as much as 11.4 percent.[18] Research on this change found that “investment increased the most for equipment with a longer recovery period and that ‘bonus depreciation had a powerful effect on the composition of investment.’”[19]

If a country cuts its corporate tax rate while limiting capital allowances, it can lead to a shift in the economy from more capital-intensive industries to sectors that rely less on capital investment. This is the case in the 2010s in the UK, which traded longer asset lives for a lower corporate tax rate and saw business investment suffer.[20] The differential treatment of capital-intensive industries over other sectors has likely contributed to the worsening of trends that have revealed significant differences in regional economic output in the UK.[21]

Capital Allowances in the OECD

The treatment of capital allowances varies greatly across OECD countries. The lowest-ranking country, Chile, allows its businesses to recover on average only 41.7 percent of capital investment costs, while the highest-ranking countries—Estonia and Latvia—allow their businesses to recover 100 percent. This wide range is largely due to countries’ vastly different corporate tax structures, depreciation schemes, and incentives designed to prioritize certain asset types over others.

Investment in industrial buildings has relatively poor tax treatment in the OECD, with an average allowance of only 48 percent. Estonia and Latvia have the best treatment of industrial buildings at 100 percent, due to their cash-flow tax systems. The countries with the lowest capital cost recovery rates for industrial buildings are Costa Rica, Hungary, and Japan, with 27.9 percent each.

Machinery generally has the best tax treatment, with an OECD average allowance of 85.3 percent. Canada and the United Kingdom are currently above average, at 100 percent, due to full expensing of investments in machinery. These policies were made permanent in the United Kingdom but phased out in Canada. Estonia and Latvia also have full cost recovery of investments in machinery, again due to their cash-flow tax systems. Of the countries without full expensing, the United States (97.5 percent) and the Czech Republic (97.2 percent) currently offer the most generous capital allowances due to temporary policies of accelerated depreciation. The countries with the worst tax treatment of investments in machinery are Chile (63.3 percent) and New Zealand (73.2 percent).

The average capital allowance for intangibles is 76.4 percent in OECD countries. Estonia and Latvia lead at 100 percent. Of the countries with deductions for intangible assets, Canada has the worst tax treatment of investments in intangibles, at 51.9 percent, followed by Australia, New Zealand, and Portugal (all 54.8 percent) and the United States (63.3 percent). Chile does not provide allowances for intangible assets.

The following map shows that the extent to which businesses can deduct their capital investment costs varies greatly across Europe.

Temporary Measures of Accelerated Depreciation

To spur capital investment during economic downturns, policymakers often temporarily increase capital allowances. Several OECD countries have done so in response to the pandemic-induced economic crisis and post-pandemic slow economic growth.

• Australia implemented two temporary depreciation measures in the first half of 2020 that apply to all businesses with revenues below AUD 500 million (USD 333 million), namely an instant asset write-off (full expensing) for depreciating assets that cost less than AUD 150,000 (up from AUD 30,000) and an accelerated depreciation deduction for all depreciable assets that are not eligible for the instant write-off. At the end of 2020, Australia implemented temporary full expensing for most assets (excluding buildings) for businesses with revenues below AUD 5 billion (USD 3.3 billion). These temporary measures will expire on 30 June 2023.[22]
• Austria accelerated depreciation for buildings in the first two years and allows businesses to depreciate machinery at a higher rate using the declining-balance method. No end date for these accelerated depreciation methods has been set so far. Additionally, an instant asset write-off (full expensing) is available for depreciating assets that cost less than EUR 1,000 (USD 1,075).
• Chile allowed full expensing of fixed assets—such as buildings and machinery—and 100 percent amortization of intangibles until the end of 2022, making it the third OECD country after Estonia and Latvia that effectively provided full expensing for industrial buildings, machinery, and intangibles. With the phaseout of this policy in 2023, the value of Chile’s capital allowances returned from the highest to the lowest in the OECD.
• The Czech Republic applied extraordinary depreciation of machinery for the years 2020 to 2023, allowing businesses to deduct 60 percent of investment costs in the first year and 40 percent in the second year.[23] The provision expires in 2024.
• Denmark made a “super deduction” available on costs concerning research and development. As a result of COVID-19, the deduction rate is increased in 2021, meaning that costs connected to research and development can be deducted at a rate of 130 percent in 2021, 105 percent in 2022, 108 percent in 2023-2025, and 110 percent from 2026 onward. The “super-deductionA super-deduction is a tax deduction that permits businesses to deduct more than 100 percent of their eligible expenses from their taxable income. As such, the super-deduction is effectively a subsidy for certain costs. This policy sometimes applies to capital costs or research and development (R&D) spending.
  ” is conditioned on the costs being connected to the taxpayer’s business. The deduction can be made either at once in the income year in which the costs are incurred, or over the course of five years, including the income year in which the costs are incurred. In 2023, Denmark reduced the straight-line rate of buildings depreciation from 4 percent to 3 percent.[24]
• Finland doubled its declining-balance depreciation rate for machinery from 25 percent to 50 percent for the years 2020 to 2023. Recently, the policy was extended until the year 2025.[25]
• Germany applied accelerated depreciation schedules for machinery from 2020 to 2022. This provision expired in 2023 and was renewed for the year 2024. The renewal was paired with accelerated depreciation for dwellings until 2029 and a permanent increase in the instant asset write-offs for depreciating assets that cost less than EUR 1,000 (USD 1,075).
• New Zealand temporarily reintroduced depreciation for commercial and industrial buildings with an estimated useful life of 50 years or more from 2020 to 2023 and temporarily increased the threshold for low-value assets that qualify for immediate write-off. Building depreciation is set to be abolished again in 2024.
• Norway has allowed for an immediate deduction against the special tax base of new investments in fixed assets used in extractive activities subject to a special oil tax since 2022.
• The United Kingdom permanently reintroduced depreciation for industrial buildings at 2 percent in 2019 and expanded it to 3 percent in 2020. In addition, the UK significantly increased capital allowances, allowing businesses to deduct 130 percent of the investment costs in plant and equipment and 50 percent for other investments, including integral features to buildings between April 1, 2021, and March 31, 2023. The super-deduction expired on March 31, 2023, and was replaced permanently by full expensing, the policy also reflected in this report.[26]

While the temporary nature of most of these expensing and accelerated depreciation provisions reduces their tax revenue impact in the long run, it also limits their long-run economic benefits. Temporary provisions may encourage businesses to shift future investments forward to take advantage of the larger deductions but would not raise the level of investment permanently. Thus, permanent full expensing across all asset types—rather than targeted temporary measures—would yield the highest economic benefits.[27]

Capital Allowances in Selected OECD Countries

Capital cost recovery varies significantly across OECD countries, as shown in Table 1 above. The following examples highlight some of the differences and recent developments.

Estonia and Latvia: Cash-Flow Tax

Estonia and Latvia have both replaced their traditional corporate income tax systems with a cash-flow tax model, which allows for a capital cost recovery rate of 100 percent. Rather than requiring corporations to calculate their taxable income using complex rules and depreciation schedules on an annual basis, the Estonian and Latvian corporate income tax of 20 percent is levied only when a business distributes profits to shareholders.

This not only simplifies the calculation of taxable profit, but it also allows for treatment of capital investment that is equivalent to full expensing. Since distributed profits are the tax base, there is no need for depreciation schedules. Instead, capital costs reduce profits in the year of investment. This treatment of capital investment encourages businesses in Estonia and Latvia to use their profits to reinvest in their firms rather than distribute them to shareholders, leading to new capital formation and increased economic growth.

Canada and the United States: Temporary Expensing for Equipment and Machinery

Currently, the United States tax code allows businesses to recover 66.7 percent of capital investment costs on average, slightly below the OECD average of 68.6 percent.

The U.S. capital allowance for intangibles is 63.3 percent, lower than the OECD average of 76.4 percent. Cost recovery of nonresidential structures is also low in the U.S., at an allowance of only 35 percent over their rather long 39-year asset lives, while the OECD average is 48 percent.

For machinery, the U.S. currently has a 97.5 percent capital cost recovery rate due to temporary bonus depreciation provided by the Tax Cut and Jobs Act (TCJA) of 2017. Since 2023, the U.S. tax code only provides 80 percent bonus depreciation, set to decline by 20 percentage points each subsequent year until full phaseout. The OECD has an average of 85.3 percent for capital allowances for machinery.

Notably, the OECD highlighted the U.S. provision in its 2018 Economic Survey of the United States, pointing out that the policy “will likely give a substantial boost to investment activity.”[28] And it did. A 2022 study found that TCJA increased U.S. companies’ capital expenditures by approximately 0.2 percent to 0.4 percent of total assets when the mean capital expenditure of U.S. firms stands at 0.9 percent.[29]

As a response to full expensing for machinery in the U.S., Canada adopted temporary full expensing for equipment and machinery used in the manufacturing and processing of goods, and for clean energy investments.[30] These assets may be fully written off in the year the equipment or machinery is put into use, instead of being depreciated over several years.

Canada also adopted accelerated depreciation schedules for non-residential buildings and intangible assets.[31] Businesses that invest in buildings used in manufacturing and processing will be able to write off 15 percent of the cost in the first year (up from 10 percent), and first-year write-offs for investments in other nonresidential buildings have been increased from 4 percent to 6 percent. For intangible assets like patents, the declining balance rate has increased from 5 to 7 percent.

The TCJA provided 100 percent bonus depreciation only through 2022, declining by 20 percentage points each year over the 2023 to 2026 period; Canada’s enhanced deductions will be in place until 2023, with a gradual phaseout period between 2024 and 2027. Although these reforms will temporarily boost investment activity, long-term effects would be significantly higher if the changes were made permanent.[32]

United Kingdom Full Expensing

From April 2021 through the end of March 2023, UK businesses could deduct 130 percent of the costs of plant and equipment (labeled “machinery” in this report). This policy was meant to assist business investment in the transition from the previous 19 percent corporate tax rate to the current 25 percent rate, which has been in place since April 2023. That’s a 130 percent increase, matching the super-deduction.

The 2023 Spring Budget substituted the super-deduction with full expensing, shifting the UK allowance for plant and equipment from a 130 percent deduction to a 100 percent deduction. This places the UK in 15th place in Table 1, while tying for first place for machinery. The temporary policy results in a whiplash effect for capital allowances, effective tax rates, and overall business investment incentives. The 2023 Spring Budget also extended a 50 percent first-year allowance to certain “integral features” and “long-life items” that do not qualify for full expensing. Further, the Annual Investment Allowance (AIA)—which provides 100 percent first-year relief for plant and machinery investments up to GBP 1 million for all businesses, including unincorporated businesses and most partnerships—was made a permanent feature of the tax code.[33]

The 2023 Autumn Statement made full expensing (and the 50 percent first-year allowance) a permanent feature of the tax code, averting an expiration of the policy in 2026. Absent permanent full expensing, the UK would have returned to an 18 percent declining balance allowance for plant and equipment, shifting from a 100 percent deduction to a 75.8 percent deduction (in net present value terms), and placing the UK in 30th place overall in Table 1. Model simulations by the Tax Foundation and the Centre for Policy Studies estimate permanent full expensing would raise GDP by 0.9 percent, investment by 1.5 percent, and wages by 0.8 percent, relative to a return to the pre-2021 law.[34]

Capital Cost Recovery in the OECD since 2000

The simple average of OECD countries’ capital cost recovery rates decreased between 2000 and 2017, followed by a slight increase in 2018 and 2019,[35] and then a significant jump in 2020 and 2021 as a response to the COVID-19 pandemic. While OECD countries allowed their businesses to deduct on average approximately 70.4 percent of their capital investments in 2000, this number decreased to 66.7 percent in 2014, reached its peak at 70.8 percent in 2022, and declined to 68.6 percent in 2023.

Weighted by GDP, the average OECD capital cost recovery rate declined slightly from 2000 (65.4 percent) to 2013 (63.8 percent). After 2017, the trend started rising quickly. Full expensing for machinery in Canada and the United States, the UK’s reintroduction of capital allowances for buildings and the super-deduction (now full expensing), and newly introduced accelerated depreciation across asset types in several OECD countries due to the COVID-19 pandemic all contributed to raising the weighted average in the last six years. In 2022, it peaked at 69 percent, rapidly declining to 67.1 percent in 2023.

As Figure 4 shows, the OECD average capital cost recovery rate weighted by each country’s GDP is consistently lower than the simple OECD average. This is because smaller economies tend to have better tax treatment of capital investment. This is also reflected in our ranking (see Table 1): Estonia, Latvia, Lithuania, the Czech Republic and Iceland—all relatively small economies—are among the countries with the best tax treatment of capital investments.

Corporate Income Tax Rates in the OECD

More attention is generally paid to the corporate income tax rate, rather than the income tax base. However, the corporate income tax base and the corporate income tax rate are both important in determining businesses’ effective tax levels. Like low capital allowances, a high corporate income tax rate reduces corporations’ after-tax profits, increases the cost of capital, and slows the growth of the capital stock. This leads to lower productivity, lower wages, and slower economic growth.[36]

In the past 23 years, countries throughout the OECD have repeatedly reduced their statutory corporate income tax rates, pushing the average rate in OECD countries to approximately 23.6 percent in 2023.[37] The OECD average of corporate income tax rates weighted by each country’s GDP has also decreased since 2000, with a significant decline between 2017 and 2018 due to the cut in the U.S. corporate income tax rate from about 32 percent to 26 percent.

Similar to capital allowances, the OECD average of corporate income tax rates weighted by each country’s GDP is consistently higher than the simple OECD average. This implies that some smaller countries tend to not only have higher capital allowances but also lower corporate income tax rates, making them more competitive from a tax perspective than some larger economies.

Conclusion

Although it has been important to reduce the distortionary effects of corporate income taxes by lowering statutory rates around the world, doing so without also considering capital allowances misses an important point of sound tax policy. Low capital allowances reduce incentives to invest, leading to lower wages and slower economic growth.

Besides pursuing policies of full expensing for capital investments, it is also important to make capital allowance provisions permanent. Permanency implies certainty, which is an essential factor for long-term investment decisions. For instance, the temporary Canadian and U.S. expensing and accelerated depreciation provisions are likely to spur economic growth in the short term. Their long-term effects, however, would be much higher if the changes were made permanent, such as in the United Kingdom.

Inflation and high interest rates also create a challenge for business investment that is exacerbated by long depreciation schedules.

To recover from the pandemic and put the global economy on a trajectory for growth, policymakers need to aim for more generous and permanent capital allowances. This will spur real investment and can also contribute to more environmentally friendly production across the globe.

Appendix

Calculating Capital Allowances: Straight-Line Method

Appendix Table 1 illustrates the calculation of a capital allowance using the straight-line method. Suppose a business made a capital investment of $100 and assume a real discount rate plus inflation that equals 7.5 percent.

In this example, the government allows investment in machinery to be deducted on a straight-line method of 12.5 percent for eight years. This means the business can deduct 12.5 percent of the initial cost of an investment each year for eight years.

Every year, the business can deduct 12.5 percent ($12.50) of the initial investment from taxable income. In the first year, the nominal value equals the present value of the write-off. However, over time, the present value of each year’s write-off declines due to the time value of money.

Although the nominal value of the entire write-off is $100, the present value is only $78.71. As a result, the company can only recover 78.71 percent of the present value of the cost of the machine by the end of the period.

Now, suppose an inflation rate of 6.9 percent. This would translate into a real discount rate plus inflation of 12.4 percent. With a higher inflation rate, although the nominal value of the entire write-off is $100, the present value is now only $68.65. As a result, the company can only recover 68.65 percent of the present value of the cost of the machine by the end of the period.

Calculating Capital Allowances: Declining-Balance Method

Appendix Table 2 illustrates the calculation of a capital allowance using the declining-balance method. Suppose a business made a capital investment of $100 and assume a real discount rate plus inflation that equals 7.5 percent.

Also, suppose the government allows investment in machinery to be deducted on a declining balance method of 20 percent for eight years. This means the business can deduct 20 percent of the remaining cost of an investment each year and the residual amount in the eighth year.

In the initial year, the business can deduct 20 percent ($20) of the initial investment from taxable income. That $20 is subtracted from the initial value of the machine. The next year, the machine has a remaining value of only $80 (the initial $100 minus the 20 percent deduction in the initial year) and, once again, 20 percent, or $16, is deducted from taxable income and subtracted from the value of the machine. In the next year, another 20 percent is deducted from the remaining $64 value of the machine, or $12.80. This method continues until the final year, when the remaining $20.97 of the investment is deducted.

Over time, the net present value of each year’s write-off declines due to the time value of money (real discount rate plus inflation). Although the nominal value of the entire write-off is $100, the present value is only $80.94. As a result, the company can only recover 80.94 percent of the present value of the cost of the machine by the end of the period.

Now, suppose an inflation rate of 6.9 percent. This would translate into a real discount rate plus inflation of 12.4 percent. With a higher inflation rate, although the nominal value of the entire write-off is $100, the present value is now only $72.22. As a result, the company can only recover 72.22 percent of the present value of the cost of the machine by the end of the period.

Countries with Unique Depreciation Schedules

While most OECD countries follow either the straight-line or declining-balance depreciation methods (or a combination of both) to determine annual capital allowances, there are some notable exceptions. The Czech Republic and Slovakia have unique depreciation schedules, and Mexico and Israel allow businesses to adjust their capital allowances for inflation.

Czech Republic and Slovakia: Specific Accelerated Depreciation Method

Besides the straight-line method, businesses may elect to depreciate buildings (only in the Czech Republic[38]) and machinery (in both countries) using a specific accelerated method. Under this method, depreciation for the first year is calculated by dividing the cost of the asset by the number of years reflecting the useful life of an asset. For subsequent years, accelerated depreciation is calculated by multiplying the residual tax value of the asset by two and then dividing it by the remaining years of depreciation plus one year.[39]

Despite this comparably complex calculation of depreciation values, Slovakia ranks 11th (73.9 percent) and the Czech Republic 5th (77.6 percent) in our comparison of capital cost recovery in the OECD, making them above average as places for business investment.[40]

Israel and Mexico: Inflation-Adjustment for Capital Allowances

Businesses in Israel and Mexico are allowed to adjust their capital allowances for inflation—a unique feature among OECD countries’ depreciation methods.[41] This allows businesses to recover a larger share of their investment costs in real terms than they otherwise would, making it a partial form of neutral cost recovery. Such inflation adjustments reduce the negative impact of long depreciation schedules on investment incentives and economic growth.

[9] Another—although slightly more complicated—way to achieve full cost recovery is a neutral cost recovery system. Under that system, write-offs are spread over time, but the deferred amounts are increased each year at a market interest rate to preserve a net present value equal to expensing. See Stephen J. Entin, “The Neutral Cost Recovery System: A Pro-Growth Solution for Capital Cost Recovery.”

[38] In 2015, Slovakia switched from its unique accelerated depreciation method for buildings to the straight-line method. It kept its accelerated method for machinery.

[39] Example: In the first year in the case of an asset with a useful life of six years, depreciation is 16.7 percent (100/6). The following years, the residual value is multiplied by two and divided by the remaining years of depreciation plus one year; i.e., for the second year: (100-16.7%) x 2 / (6-1+1) = 27.77%.

[40] For the years 2020 to 2023, the Czech Republic allowed the cost of machinery to be written off by 60 percent in the first year and the remainder in the second year.
