This article lists countries by total tax revenue as a percentage of gross domestic product (GDP) for the listed countries. Three sources are used, one for each column. The tax percentage for each country listed in the sources has been added to the chart.
Warning: tax rates do not seem to include state and local taxes because it requires a lot of work to collect data from sub-national entities. See talk page for more discussion.
- Note: This list is sortable in various ways. Click the sort buttons at the top of the chart. Countries can be displayed in numerical order by clicking the buttons at the top of the number columns. The table can be put in forward or reverse alphabetical order by clicking the sort button at the top of the country column.
