The tax system is quite complicated in Poland Shutterstock

Poland has a relatively low top tax bracket, set at 32 percent. However, the real taxation level is almost as high as in Sweden, indicates a report by a consulting firm KPMG, which analyzed taxes and other deductions from individuals' income in 114 countries.

With 35 percent of citizens' income going to taxes and social contributions, Poland ranks 25th in the ranking encompassing. Belgians, Greeks and Croatians pay the most in taxes.

But in countries, which have the highest income tax brackets for the rich, citizens don't always incur high costs. For example, in Sweden the highest tax rate equals 56.6 percent. However, Swedes who make $100,000 a year in fact pay 40 percent of their total income in taxes and contributions when deductions are taken into account.

KPMG calculated the taxes of individuals who make the equivalent of $100,000 and $300,000 a year. Besides income tax KPMG also took into consideration insurance premiums and other social contributions. "There is a debate on whether social contributions can indeed be considered taxes, but they constitute a significant cost and that's why they cannot be ignored," the authors of the KPMG report explain.
