Introduction

It is well known that the United States has the highest corporate income tax rate among the 34 industrialized nations of the Organisation for Economic Co-operation and Development (OECD).[1] However, it is less well known how the United States stacks up against countries throughout the entire world. Expanding the sample of countries and tax jurisdictions to 173, the U.S.’s corporate tax rate of 39 percent is the third highest in the world, tied with Puerto Rico and lower only than the United Arab Emirates and Chad, which have rates of 55 and 40 percent, respectively. The U.S. tax rate is 16 percentage points higher than the worldwide average of 22.8 percent and a little more than 9 percentage points higher than the worldwide GDP-weighted average of 29.8 percent. As with the average tax rate among industrialized nations, the average worldwide tax rate has been declining in the past ten years, pushing the United States farther from the norm. This worldwide decline in corporate tax rates can been seen in all regions of the world.

The United States Has the Third Highest Corporate Tax Rate among 173 Nations

The top marginal corporate tax rate among the 173 countries surveyed was the United Arab Emirates,[2] which has a top rate of 55 percent (Table 1).[3] This is followed by the African nation Chad (40 percent). The United States, with a combined top marginal tax rateThe marginal tax rate is the amount of additional tax paid for every additional dollar earned as income. The average tax rate is the total tax paid divided by total income earned. A 10 percent marginal tax rate means that 10 cents of every next dollar earned would be taken as tax. of 39 percent (consisting of the federal tax rate of 35 percent plus the average tax rateThe average tax rate is the total tax paid divided by taxable income. While marginal tax rates show the amount of tax paid on the next dollar earned, average tax rates show the overall share of income paid in taxes. among the states), has the third highest corporate income tax rate in the world, along with Puerto Rico. In contrast, the average across all 173 countries is 22.9 percent, or 29.8 percent weighted by gross domestic product.[4]

Every region in the world except for Oceania is represented in the top twenty countries. Six of the top twenty countries are in Africa, two of the top twenty countries are in Asia, and one is in Europe. The nine remaining countries are in South and North America.

Other large nations in the top twenty countries besides the United States are France (34.4 percent), Brazil (34 percent), and India (34 percent).

Among countries with corporate income taxes, Turkmenistan and Uzbekistan have the lowest top marginal rate at 8 percent (Table 2). Nine countries have top rates of 10 percent, most of them small nations in Europe (Bosnia and Herzegovina, Macedonia, Gibraltar, Andorra, Bulgaria). The only major industrialized nation[5] among the bottom 20 countries is Ireland, which is known for its low 12.5 percent rate.

Of the 173 countries surveyed, there are currently 10 countries without a corporate income tax (table 3). Most countries without corporate income taxes are small, island nations. Four of the ten countries are islands known for having no corporate income tax: the Bahamas, the Cayman Islands, the British Virgin Islands, and Bermuda. Bahrain has no general corporate income tax, but has a targeted corporate income tax on oil companies.[6]

Regional Variation in Corporate Tax Rates

Corporate tax rates vary significantly between worldwide regions (Table 4). Africa’s average top marginal corporate income tax rate of 28.77 percent is the highest among all regions. Europe has the lowest average tax rate at 18.7 percent, 4 percentage points below the worldwide average of 22.9 percent.

Weighted by gross domestic product, North America stands as the region with the highest average top marginal corporate tax rate at 37 percent. This is unsurprising given that the United States makes up more than 80 percent of the region’s GDP and has a corporate tax rate of 39 percent. Europe also has the lowest weighted average top marginal corporate tax rate at 26.1 percent.

Larger, more industrialized countries tend to have higher corporate income tax rates than the world as a whole. The G7, which is a group of the 7 largest nations in the world by net wealth, has an average corporate income tax rate of 30.7 percent (33.96 percent weighted). The 34 nations of the OECD have an average corporate tax rate of 25 percent (31.6 percent weighted). The BRICS (Brazil, Russia, India, China, and South Africa) have an average rate of 28.32 percent (27.3 percent weighted).

There Are Few Countries with Corporate Tax Rates above 35 Percent

The United States stands as one of the few nations in the world that has a top corporate income tax rate above 35 percent. The following chart (Chart 1) shows the distribution of the corporate tax rates among 173 countries and tax jurisdictions in 2015. A plurality (43) of the countries in the world have corporate income tax rates between 25 and 30 percent. 22 countries have tax rates between 30 and 35 percent. The United States is one of only four countries in the world that has a corporate tax rate over 35 percent. Sixty-eight countries have corporate tax rates between 0 and 20 percent.

Corporate Tax Rates around the World Have Fallen in the Past Decade

Reductions in corporate income tax rates in the past twelve years have occurred across the globe, reducing considerably the worldwide average tax rate (Chart 2). In 2003, the worldwide average was approximately 30 percent. By 2015, the average rate had declined by a little more than 7 percentage points to 22.8 percent.

The average top marginal corporate tax rate weighted by GDP has not declined as much. This is mainly due to the fact that the United States, which makes up approximately 25 percent of world GDP, continues to have a high 39 percent corporate income tax rate that has not changed in over 10 years. Nonetheless, the worldwide GDP-weighted average tax rate has declined from 35.5 percent to 29.8 percent in the last 10 years.

Chart 2.

This downward trend holds across all regions of the globe (Chart 3). The average top marginal corporate tax rate in all regions has declined in the past decade.

The largest absolute drop in average top marginal corporate tax rates was in Asia. The average declined from 31 percent in 2003 to 20.6 percent in 2015, approximately a 10 percentage point decline. South American countries reduced their corporate income tax rates the least, from 29.9 percent to 27.92 percent over the last twelve years.

Conclusion

The corporate income tax rate is one of many aspects of what makes a country’s tax code and economy attractive for investment. However, as the rest of the world’s economies mature and their tax rates on corporate income continue to decline, the United States risks losing its competitive edge due to its exceptionally high corporate income tax rate.
