Tax Revenue by Country (2020)

Global Tax Collection

Tax revenue as a percentage of GDP measures a government's fiscal capacity. Nordic countries collect 40-50% of GDP in taxes, funding comprehensive welfare states with universal healthcare, free education, and generous social safety nets — while still ranking among the world's most competitive economies. Many developing countries collect less than 15% — below the IMF's threshold for funding basic services — reflecting large informal economies, weak tax administration, and narrow tax bases. The relationship between tax level and growth is nuanced: high-tax Nordic economies and low-tax Singapore have both achieved prosperity.
