Today’s map looks at how European OECD countries rank on international tax rules and is the last in our series examining each of the five components of our 2020 International Tax Competitiveness Index (ITCI). International tax rules define how income earned abroad and by foreign entities are taxed domestically, making them an important element of each country’s tax code.
The ITCI’s international tax rules component compares various aspects of OECD countries’ international tax systems, namely territoriality, withholding taxes, tax treaties, and international tax regulations such as controlled foreign corporations (CFC) rules and thin-capitalization rules.
Territoriality defines the extent to which foreign-earned dividends and capital gains are included in the domestic tax base. Tax treaties align many tax laws between two countries and attempt to reduce double taxation, partly by reducing or eliminating withholding taxes on dividends, interest, and royalties earned by foreign individuals and businesses. CFC and thin-capitalization rules seek to prevent multinational businesses from minimizing their tax liability through base erosion and profit shifting.
The United Kingdom’s international tax system ranks highest in the OECD. Like most OECD countries, the UK operates a territorial tax system, fully exempting foreign-earned dividends and capital gains from domestic taxation. The UK has the broadest tax treaty network in the OECD, at around 130 countries. As a result, depending on the tax treaty, foreign entities from these countries are either not subject to the 20 percent withholding tax on interest and royalties earned in the UK or pay a reduced rate. There is no withholding tax on dividends. The UK has relatively strict CFC rules and thin-capitalization rules.
Among European OECD countries, Slovakia has the least competitive international tax system (Chile ranks the lowest in the OECD). While Slovakia excludes foreign-earned dividends and capital gains from its domestic tax base, it levies a relatively high withholding tax of 35 percent on dividends (interest and royalties are subject to a 19 percent withholding tax). Slovakia’s tax treaty network consists of approximately 70 countries, and its CFC and thin-capitalization rules are relatively strict.
