2016 International Tax Competitiveness Index
The structure of a country’s tax code is an important determinant of its economic performance. A well-structured tax code is easy for taxpayers to comply with and can promote economic development, while raising sufficient revenue for a government’s priorities. In contrast, poorly structured tax systems can be costly, distort economic decision making, and harm domestic economies.
Many countries have recognized this and have reformed their tax codes. Over the past few decades, marginal tax rates on corporate and individual income have declined significantly across the Organisation for Economic Co-operation and Development (OECD). Now, most nations raise a significant amount of revenue from broad-based taxes such as payroll taxes and value-added taxes (VAT).
New Zealand is a good example of a country that has reformed its tax system. In a 2010 presentation, the chief economist of the New Zealand treasury stated, “Global trends in corporate and personal taxes are making New Zealand’s system less internationally competitive.” In response to these global trends, New Zealand cut its top marginal individual income tax rate from 38 percent to 33 percent, shifted to a greater reliance on the goods and services tax, and cut its corporate tax rate to 28 percent from 30 percent. New Zealand added these changes to a tax system that already had multiple competitive features, including no inheritance tax, no general capital gains tax, and no payroll taxes.
Some nations, however, have not kept up with the global trend. The United States, for example, has not reduced its federal corporate income tax rate from 35 percent since the early 1990s. As a result, its combined federal, state, and local corporate tax rate of 39 percent is significantly higher than the average rate of 25 percent among OECD nations. In addition, as most OECD nations have moved to a territorial tax system, the United States has continued to tax the worldwide profits of its domestic corporations.
Other nations have moved further from well-structured tax policy. Over the last few decades, France has introduced a number of reforms that have significantly increased marginal tax rates on work, saving, and investment. For example, France recently instituted a corporate income surtax that pushed its corporate income tax rate from 33.3 percent to as high as 38 percent. In addition, it has other distortive taxes such as the financial transactions tax, a net wealth tax, and an inheritance tax.

The International Tax Competitiveness Index (ITCI) seeks to measure the extent to which a country’s tax system adheres to two important aspects of tax policy: competitiveness and neutrality.
A competitive tax code is one that keeps marginal tax rates low. In today’s globalized world, capital is highly mobile. Businesses can choose to invest in any number of countries throughout the world in order to find the highest rate of return. This means that businesses will look for countries with lower tax rates on investment in order to maximize their after-tax rate of return. If a country’s tax rate is too high, it will drive investment elsewhere, leading to slower economic growth. In addition, high marginal tax rates can drive tax avoidance.
A neutral tax code is simply one that seeks to raise the most revenue with the fewest economic distortions. This means that it doesn’t favor consumption over saving, as happens with investment taxes and wealth taxes. This also means few or no targeted tax breaks for specific activities carried out by businesses or individuals.
A tax code that is competitive and neutral promotes sustainable economic growth and investment while raising sufficient revenue for government priorities.
There are many factors unrelated to taxes which affect a country’s economic performance. Nevertheless, taxes play an important role in the health of a country’s economy.
In order to measure whether a country’s tax system is neutral and competitive, the ITCI looks at more than 40 tax policy variables. These variables measure not only the specific burden of taxes, but also how taxes are structured. The index looks at a country’s corporate taxes, individual income taxes, consumption taxes, property taxes, and the treatment of profits earned overseas. The ITCI gives a comprehensive overview of how developed countries’ tax codes compare, explains why certain tax codes stand out as good or bad models for reform, and provides important insight into how to think about tax policy.
For the third year in a row, Estonia has the best tax code in the OECD. Its top score is driven by four positive features of its tax code. First, it has a 20 percent tax rate on corporate income that is only applied to distributed profits. Second, it has a flat 20 percent tax on individual income that does not apply to personal dividend income. Third, its property tax applies only to the value of land rather than taxing the value of real property or capital. Finally, it has a territorial tax system that exempts 100 percent of the foreign profits earned by domestic corporations from domestic taxation, with few restrictions.
While Estonia’s tax system is unique in the OECD, the other top countries’ tax systems receive high scores due to excellence in one or more of the major tax categories. New Zealand has a relatively flat, low-rate income tax that also exempts capital gains (with a combined top rate of 33 percent), a well-structured property tax, and a broad-based value-added tax. Latvia, which recently joined the OECD, has a relatively low corporate tax rate of 15 percent, speedy cost recovery, and a flat individual income tax. Switzerland has a relatively low corporate tax rate (21.1 percent), a low, broad-based consumption tax, and a relatively flat individual income tax that exempts capital gains from taxation. Sweden has a lower than average corporate income tax rate of 22 percent, no estate or wealth taxes, and a well-structured value-added tax and individual income tax.
For the third year in a row, France has the least competitive tax system in the OECD. It has one of the highest corporate income tax rates in the OECD (34.4 percent), high property taxes, an annual net wealth tax, a financial transaction tax, and an estate tax. France also has high, progressive, individual income taxes that apply to both dividend and capital gains income.
In general, countries that rank poorly on the ITCI levy relatively high marginal tax rates on corporate income. The five countries at the bottom of the rankings all have higher than average corporate tax rates. All five countries have high consumption taxes, with rates of 20 percent or higher, except for the United States. They also levy relatively high property taxes on real property and have estate taxes. Finally, these bottom five countries have relatively high, progressive income taxes that apply to capital gains and dividends.
Notable Changes from Last Year
Since last year, several countries’ tax codes have undergone notable changes that have impacted their rankings. Table 2, below, shows both the rank and score changes for each country from last year and 2014.
|Country||2014 Rank||2014 Score||2015 Rank||2015 Score||2016 Rank||2016 Score||Change in Rank||Change in Score|
Belgium lengthened depreciation lives of intangible assets, boosted its VAT threshold from $6,300 to $30,400, and slightly reduced its top marginal income tax rate from 59.4 percent to 58.3 percent. In addition, it increased withholding taxes. As a result, Belgium fell two places, from 26th to 28th.
In 2014, Chile enacted a major tax reform that, among other things, increased its corporate income tax, changed how shareholders are taxed, and strengthened anti-avoidance rules. This year, the tax reform continued to phase in. The corporate income tax rate increased from 22.5 to 24 percent, capital gains are now taxed as ordinary income, and the top marginal individual income tax rate is now 40 percent. As a result of these changes, Chile’s rank fell from 29th to 30th.
Denmark improved from 22nd to 21st place as it continues to phase-in a corporate rate reduction from 24 percent in 2014 to 22 percent in 2016.
Greece dropped four spots, from 28th to 32nd. The fall is due to changes to both its corporate income tax and individual income tax. Greece increased its corporate income tax from 26 percent to 29 percent, raised its top marginal income tax rate from 45 to 50 percent, and introduced a special “solidarity charge” on individual income.
Ireland fell two spots, from 12th to 14th place. This move was driven by the introduction of a “patent box,” which provides a special rate of 6.25 percent to profits attributable to patents.
Israel made several changes to its tax system in the past year. Israel cut its corporate income tax rate from 26.5 percent to 25 percent. It reduced its value-added tax from 18 percent to 17 percent while slightly narrowing the base. Israel also increased its dividend tax rate from 30 percent to 32 percent and slightly increased its tax burden on wage earners from 20.5 percent to 21.5 percent. Lastly, it cut withholding taxes from 26.5 percent to 25 percent for both interest and royalty payments. On net, Israel’s rank improved from 27th to 26th place.
Japan continues to phase in a corporate rate cut. Its corporate income tax rate fell from 32.1 percent in 2015 to 29.9 percent in 2016. However, Japan fell one place, from 24th to 25th, due mainly to a narrowing of its VAT base and an increase in its top marginal income tax rate from 51 percent to 56.1 percent.
Korea fell from 11th to 12th place. Korea worsened cost recovery by limiting loss carryforwards to eight years, from 10 years. In addition, corporate tax complexity increased, as reflected in longer compliance time and an increase in the number of required payments.
Mexico improved from 25th to 24th place. This improvement was driven primarily by improvements in its corporate compliance time (measured in hours a year), which declined from 170 hours to 122 hours. Conversely, Mexico’s top marginal income tax rate increased from 31.65 percent to 35 percent and applies narrowly to income 29 times the average national income.
Norway enacted a number of changes that impacted the taxation of capital income in 2016. Norway reduced its corporate income tax rate from 27 percent to 25 percent. In addition, it reduced its capital gains tax rate from 27 percent to 25 percent and raised its dividend tax rate from 27 percent to 28.75 percent. Norway’s rank improved from 13th to 11th place.
Spain improved four places, from 31st to 27th, due to a number of improvements to its tax code. It improved its corporate tax by reducing the rate from 30 percent to 28 percent, speeding up cost recovery for both machinery and buildings, and by reducing compliance costs. Spain also improved its individual income tax system. It reduced its capital gains and dividend tax rates from 24 percent to 23 percent, reduced its top marginal tax rate on ordinary income from 52 percent to 46 percent, and flattened the tax system by applying its top rate to income over 2.4 times the average national income, down from 11.6 times.

 Due to some data limitations, some recent tax changes in some countries may not be reflected in this year’s version of the International Tax Competitiveness Index. Last year’s scores published in this report can differ from previously published rankings due to methodological changes and corrections made to previous years’ data.
