Corporate tax avoidance is not a loophole in the law; it is a feature of the law. When a multinational corporation books profits in a low-tax jurisdiction, shifts intangible assets into a subsidiary, or times deductions against a favorable rate schedule, the arithmetic is simple: the revenue that does not arrive at the Treasury must be replaced. The replacement usually comes from individual taxpayers—through higher effective rates on wages, reduced public services, or larger deficits that are later financed by payroll and income taxes. This article examines the distributional mechanics of that shift, with attention to the tax expenditure budget, transfer pricing rules, and the quiet conventions that make corporate avoidance look like neutral bookkeeping.
The Hidden Subsidy Inside the Corporate Tax Base
Most public discussion of corporate taxation begins with the statutory rate. That is a mistake. The statutory rate is a headline; the effective rate is the policy. The difference between the two is a tax expenditure—a subsidy delivered through the tax code rather than through a direct appropriation. The Joint Committee on Taxation publishes an annual list of these expenditures, and the corporate side is dominated by accelerated depreciation, the deduction for foreign-derived intangible income, and the deferral of active foreign income. Each of these provisions reduces corporate liability below the statutory benchmark, and each has a distributional consequence.
Consider accelerated depreciation. A firm that buys a machine may deduct its cost faster than the machine actually wears out. That timing difference is an interest-free loan from the Treasury. The loan is not distributed randomly. It goes to firms with enough capital expenditure to matter, which means large, established corporations rather than new entrants. The cost of the loan is borne by the general revenue fund, which is financed disproportionately by individual income and payroll taxes. In 2023, individual income taxes and payroll taxes together accounted for roughly 86 percent of federal receipts, while corporate income taxes accounted for about 9 percent. The arithmetic of that split is the real distributional story.
Transfer Pricing and the Geography of Profit
Transfer pricing is the most powerful avoidance tool available to a multinational firm. The concept is simple: when two subsidiaries of the same parent trade with each other, they must set a price as if they were independent parties. The practice is less simple. Intangible assets—patents, trademarks, algorithms, brand value—are notoriously difficult to price. A pharmaceutical company can assign a patent to a subsidiary in a low-tax country, then have the U.S. subsidiary pay a royalty to use that patent. The royalty is deductible in the United States and taxable at a low rate abroad. The result is that profit is reported where the tax rate is lowest, not where the economic activity occurs.
The Internal Revenue Service has rules to police this, but the rules are fighting a war of attrition. The IRS must value intangibles that have no observable market price. The corporation has an incentive to choose a low value for the royalty, and the IRS must prove the value is wrong. The burden of proof, the cost of litigation, and the asymmetry of information all favor the taxpayer. The result is a steady leakage of corporate tax base out of the United States, a leakage that is made up by individual taxpayers who cannot shift their wages to Bermuda.
The Role of Cost-Sharing Agreements
Cost-sharing agreements are a specific transfer pricing device that deserves attention. Under these agreements, a U.S. parent and a foreign subsidiary agree to share the costs of developing an intangible asset in exchange for shared rights to the income from that asset. The problem is the buy-in payment. When the foreign subsidiary enters the agreement, it must pay the U.S. parent for the value of the pre-existing intangibles it will now share. That buy-in payment is supposed to reflect the fair market value of the intangibles. In practice, the buy-in is often set far below the value that the intangibles will generate. The Treasury loses revenue on the difference, and the loss is shifted to the individual tax base.
Tax Expenditures Are Spending in Disguise
The most important conceptual shift for understanding corporate avoidance is to treat tax expenditures as spending. A deduction is not a reduction in taxes; it is a payment made through the tax code. The distinction matters because the distributional analysis of spending is different from the distributional analysis of taxation. When Congress appropriates money for a program, the appropriation is visible, debated, and subject to annual review. When Congress creates a deduction, the subsidy is invisible, automatic, and often permanent. The invisibility is the point.
The corporate tax expenditure budget is large. The Joint Committee on Taxation estimated that the five largest corporate tax expenditures—accelerated depreciation, the foreign-derived intangible income deduction, the research credit, the low-income housing credit, and the deferral of active foreign income—would reduce federal revenue by hundreds of billions of dollars over a ten-year window. Each of those dollars is a dollar that must be raised elsewhere. The elsewhere is the individual income tax, the payroll tax, or the deficit. The deficit is not a neutral option; it is a deferred tax on future individuals, with interest.
Who Bears the Corporate Tax? A Distributional Note
There is a long-standing debate in public finance about who bears the corporate income tax. The traditional view is that the burden falls on owners of capital in the short run and on workers in the long run, as capital moves abroad and reduces domestic productivity and wages. The newer view is that a significant share of the burden falls on labor even in the short run, because labor is less mobile than capital. Either way, the distributional conclusion is the same: the corporate tax is not a tax on an abstract entity. It is a tax on people, and the people who bear it are not the people who sign the corporate return.
When a corporation avoids tax, the burden does not disappear. It shifts. The shift is from the owners of capital to the earners of wages. The shift is from the shareholders of multinational firms to the workers who cannot relocate their labor to a low-tax jurisdiction. The shift is from the wealthy, who own a disproportionate share of corporate equity, to the middle class, who pay a disproportionate share of payroll and income taxes. The shift is the policy.
Measurement Conventions That Hide the Shift
The distributional shift is hidden by measurement conventions. The most important convention is the use of the statutory rate as the benchmark for tax expenditures. The statutory rate is a policy choice, not a fact of nature. If the statutory rate were lower, the measured tax expenditure would be smaller, even if the actual subsidy were unchanged. The choice of benchmark is a political act, and it is usually made by the same institutions that benefit from the subsidy.
A second convention is the treatment of deferred taxes. When a corporation defers tax on foreign income, the deferral is not counted as a current-year expenditure. It is counted as a timing difference, as if the tax will eventually be paid. But the deferral can be indefinite, and the present value of a tax paid decades later is far less than the present value of a tax paid now. The convention of ignoring present value makes the deferral look smaller than it is.
A third convention is the exclusion of certain items from the tax expenditure budget altogether. The most important exclusion is the step-up in basis at death, which allows unrealized capital gains to escape income tax entirely. The step-up is not a corporate tax expenditure, but it is a corporate-adjacent subsidy that shifts the tax burden from wealthy estates to wage earners. The convention of excluding it from the corporate tax expenditure budget makes the corporate side look cleaner than it is.
Historical Comparisons: The 1950s and the Architecture of Avoidance
The current architecture of corporate avoidance was not built overnight. It was built piece by piece, often in response to specific corporate complaints. In the 1950s, the corporate income tax raised about 30 percent of federal revenue. Today it raises about 9 percent. The decline is not the result of a single law. It is the result of a thousand small changes: the creation of the foreign tax credit, the expansion of accelerated depreciation, the invention of the check-the-box rules, the introduction of the domestic production activities deduction, the replacement of that deduction with the foreign-derived intangible income deduction. Each change was justified on its own terms. Each change reduced the corporate tax base. Each change shifted the burden to individuals.
The historical comparison is useful because it shows that the current distribution is a choice. The 1950s were not a golden age of corporate taxation; they were a period when the corporate tax base was broader and the statutory rate was higher. The shift since then is not a natural evolution. It is a political project, carried out by the people who benefit from it.
What Individuals Pay for Corporate Avoidance
The cost of corporate avoidance to individual taxpayers can be measured in several ways. The most direct measure is the revenue loss. The Joint Committee on Taxation estimates that the corporate tax expenditures listed above reduce federal revenue by hundreds of billions of dollars over ten years. That revenue loss must be offset by higher individual taxes, lower spending, or larger deficits. The offset is not hypothetical. It is the reason that the individual income tax has become the dominant source of federal revenue, even as the statutory corporate rate has fallen.
A second measure is the distribution of the tax burden. The Congressional Budget Office publishes estimates of the distribution of federal taxes by income group. Those estimates show that the federal tax system is progressive overall, but the progressivity is driven almost entirely by the individual income tax. The corporate income tax is less progressive than the individual income tax, and the payroll tax is regressive. When the corporate tax base shrinks, the system becomes less progressive, because the revenue must be replaced by taxes that fall more heavily on lower- and middle-income households.
A third measure is the effect on public services. When corporate tax revenue declines, the federal government has less money to spend on infrastructure, education, health care, and research. Those services are used disproportionately by lower- and middle-income households. The decline in corporate tax revenue is therefore a transfer from the users of public services to the owners of corporate equity. The transfer is hidden by the language of tax policy, but it is real.
The Payroll Tax Connection
The payroll tax is the quiet partner in this story. The payroll tax is the largest tax that most workers pay, and it is dedicated to Social Security and Medicare. The payroll tax is regressive: it applies only to wages, not to capital income, and it is capped at a certain level of earnings. When corporate tax avoidance reduces general revenue, the pressure to raise payroll taxes increases, because the payroll tax is the most reliable source of federal revenue. The result is a double shift: corporate avoidance reduces the corporate tax base, and the response is to increase a regressive tax on wages. The workers who pay the payroll tax are the same workers whose wages are depressed by the corporate tax burden. The circle is closed.
What Can Be Done: Policy Options and Their Limits
The policy options for addressing corporate tax avoidance fall into three categories. The first is to broaden the corporate tax base by eliminating or reducing tax expenditures. This is the most direct approach, but it is also the most politically difficult, because each tax expenditure has a constituency. The second is to strengthen enforcement, particularly in the area of transfer pricing. This approach is less visible but potentially significant, because the IRS has historically been underfunded relative to the sophistication of the taxpayers it audits. The third is to change the international tax rules, either through a global minimum tax or through a shift to a destination-based cash flow tax. Each of these options has tradeoffs, and none is a complete solution.
The limits of policy are important to acknowledge. Corporate tax avoidance is not a technical problem that can be solved by better rules. It is a distributional conflict, and the rules are the terrain of the conflict. The corporations that benefit from avoidance have the resources to influence the rules, and they have done so for decades. Any reform that threatens their interests will be opposed, and the opposition will be well-funded. The question is not whether the rules can be improved; the question is whether the political system can overcome the interests that benefit from the current rules.
Frequently Asked Questions
What is the difference between the statutory corporate tax rate and the effective corporate tax rate?
The statutory rate is the rate set by law—currently 21 percent at the federal level. The effective rate is what a corporation actually pays after deductions, credits, deferrals, and other tax expenditures. The effective rate is usually much lower than the statutory rate, and the difference is the subsidy delivered through the tax code.
How does corporate tax avoidance affect individual taxpayers?
When corporations avoid tax, the federal government loses revenue. That revenue must be replaced by higher individual taxes, lower public spending, or larger deficits. The replacement falls disproportionately on wage earners, who cannot shift their income to low-tax jurisdictions the way corporations can.
What is a tax expenditure?
A tax expenditure is a provision in the tax code that reduces tax liability for a particular activity or group. It is functionally equivalent to a direct spending program, but it is delivered through the tax system rather than through an appropriation. Tax expenditures are less visible than direct spending, which makes them easier to maintain and harder to cut.
Why is transfer pricing so difficult to regulate?
Transfer pricing requires valuing transactions between related parties as if they were independent. For tangible goods, this is difficult. For intangible assets like patents and trademarks, it is nearly impossible, because there is no observable market price. The asymmetry of information between the corporation and the IRS gives the corporation a structural advantage.
Conclusion: The Rules Are Built, Not Given
The distributional shift from corporate tax avoidance to individual taxpayers is not a natural feature of the economy. It is the result of specific rules, written by specific people, for specific purposes. The rules can be changed, but only if the people who bear the cost understand the mechanics of the shift. The first step is to stop treating corporate tax avoidance as a technical problem and start treating it as a distributional policy. The second step is to make the hidden subsidies visible, by measuring tax expenditures as spending and by reporting effective rates alongside statutory rates. The third step is to ask, in every tax debate, the question that is almost never asked: who pays?
