The WEF looks at data on areas as varied as the quality of the teaching of math in schools to the rate of inflation in each country. It then uses the data to compile a picture of virtually every country.

One of the indicators the WEF uses is a country's tax burden, with higher scores indicating lower competitiveness.

To measure tax it uses the World Bank's total tax rate. Here's what goes into that:

The total amount of taxes is the sum of five different types of taxes and contributions payable after accounting for deductions and exemptions: profit or corporate income tax, social contributions and labor taxes paid by the employer, property taxes, turnover taxes, and other small taxes.

Basically, it's all the taxes levied on businesses but not those levied on the people who work for them. Business Insider took a look at the countries with total tax rates of more than 50%. Check them out below.
