Everything that was wrong with the US tax system—in one chart

A poor trade-off

A 2014 international tax comparison placed the United States near the bottom of the OECD countries it assessed. The result was notable not merely because the system was viewed as difficult for investment, but because it raised relatively little government revenue at the same time.

The index defined competitiveness primarily through the way taxes affected businesses, saving and investment. Under that framework, high rates, complex provisions and rules that steered companies toward tax-driven decisions counted against a country. This was one perspective on tax design, not a complete measure of whether a system was fair or whether public spending was worthwhile.

The organisation responsible for the index was often associated with a market-oriented view of tax policy. That background matters when interpreting the score. It also clarifies what the measure was designed to capture: features that businesses could see as costly when choosing where to invest, how to finance operations and where to recognise income.

What the chart showed

The original analysis plotted the 2014 competitiveness score against total government revenue as a share of gross domestic product. Revenue included tax and non-tax receipts collected by central, regional and local government. Among the countries for which both measures were available, the United States appeared in the lower-left area: weak on the index and low on revenue collection.

France offered one comparison. Its tax structure also received a low rating, but it supported a much larger public sector. Denmark collected an even greater share of national output while receiving a score closer to the OECD middle. Estonia, meanwhile, led the index because its system was regarded as comparatively simple and neutral under the index methodology.

Why the amount paid was only part of the burden

One common response to high statutory corporate tax rates was that many companies paid a much lower effective rate after deductions, credits and international tax planning. That observation was relevant, but it did not capture all the costs imposed by the system.

Reducing a tax bill could require changes to financing, legal structure, headquarters, intellectual-property ownership or operating decisions. Those actions could involve professional fees, administrative work and lost commercial opportunities. A tax system therefore could raise limited revenue while still influencing business behaviour in expensive ways.

A simplified historical example

Consider a company expecting $100 million in profit and a $35 million tax bill under the assumptions used in the original article. A restructuring might cut the tax bill to $10 million, while imposing $10 million in administrative expense and reducing revenue by another $10 million.

The company would still be better off than if it had taken no action, but the effective burden would not be represented fully by the final tax payment. The broader economic cost included resources spent adapting to the rules.

Neutrality and tax design

The index favoured systems intended to collect revenue while creating fewer incentives to change saving, investment or business decisions. In its methodology, neutrality meant avoiding narrow preferences for selected industries or activities and limiting differences in the treatment of economically similar choices.

Estonia was presented as the leading 2014 example. The features highlighted at the time included taxation of corporate profit when distributed, a comparatively simple individual income-tax structure, land-focused property taxation and territorial treatment of much foreign business income. Those details reflected the rules and index assessment then in force.

That model was not the only possible route to reform, and the index did not resolve questions about distribution, public services or the appropriate overall level of taxation. It did, however, support a broader principle: lower headline rates work best when paired with a broader base and fewer special provisions.

The reform lesson

The archive argument favoured revenue-neutral corporate tax reform: reduce the top rate, close loopholes and simplify the base so that business choices depended less on tax engineering. Whether a specific reform meets those goals requires careful modelling of revenue, incidence, transition costs and international responses.

The enduring lesson is methodological. Evaluating a tax system requires more than asking how much revenue it collects or what its highest rate is. A fuller assessment considers compliance expense, behavioural distortions, distribution, stability and whether similar economic activities receive similar treatment.
