This article lists countries alphabetically, with total tax revenue as a percentage of gross domestic product (GDP) for the listed countries. The tax percentage for each country listed in the source has been added to the chart.
According to World Bank, "GDP at purchaser's prices is the sum of gross value added by all resident producers in the economy plus any product taxes and minus any subsidies not included in the value of the products. It is calculated without making deductions for depreciation of fabricated assets or for depletion and degradation of natural resources. Data are in current U.S. dollars. Dollar figures for GDP are converted from domestic currencies using single year official exchange rates. For a few countries where the official exchange rate does not reflect the rate effectively applied to actual foreign exchange transactions, an alternative conversion factor is used. Tax revenue refers to compulsory transfers to the central government for public purposes. Certain compulsory transfers such as fines, penalties, and most social security contributions are excluded. Refunds and corrections of erroneously collected tax revenue are treated as negative revenue."
UNU-WIDER data is more complex, total taxes consists of direct and indirect taxes paid to all levels of government. Total taxes excludes social contributions. Sources are IMF Country Reports and OECD Revenue Statistics. Data are in current national currency.
Hypothetical examples The examples assume the two countries are identical in all other respects.
In Centralia, people pay 50% of their salary as income tax to the national government. In Federalia, people pay 25% of their salary as national income tax and 25% as provincial income tax. In column 5 (% of GDP), Federalia will have a much lower number than Centralia, because the World Bank data only counts central government taxation. In Simplicia, people pay 50% of their salary in income tax to the national government, which pays €500 a month to each old person. In Complexia, people pay 25% of their salary as income tax to the national government, and 25% of their salary to the National Pension Fund, which pays €500 a month to each old person. In column 5 (% of GDP), Complexia will have a much lower number than Simplicia, because the World Bank data excludes social security contributions.
