Tax Revenue as Percentage of GDP — – Tax Revenue (% of GDP) refers to the total tax revenue collected by the central government, expressed as a percentage of Gross Domestic Product (GDP). Tax revenue consists of compulsory, unrequited payments made by individuals and businesses to the government for public purposes. The indicator measures the relative size of tax collections compared with the overall economy and is widely used to assess a government's revenue-generating capacity, fiscal performance, and tax effort.
Measured as a Percentage, the regional dataset covers 2015–2024 and indicates that North America's tax revenue averaged between 10.13% and 12.70% of GDP during the period. The regional ratio stood at 11.29% in 2015, declined to 10.13% in 2019, recovered steadily to 11.61% in 2021, reached a decade high of 12.70% in 2022, and moderated to 11.02% in 2024, reflecting changing economic conditions and fiscal policy developments across the region. The regional trend is primarily influenced by the United States, the largest economy in North America, where the tax-to-GDP ratio fluctuated between 9.88% and 12.61% over the decade, including a peak in 2022 before easing to 10.77% in 2024. Canada consistently recorded the region's highest tax revenue ratio among the major economies, maintaining levels above 12% throughout the period and reaching 14.00% in 2021 before stabilizing at 13.71% in 2024. Mexico, although not included in the regional aggregate presented here, also demonstrated strengthening tax collection over the decade, with its tax-to-GDP ratio rising from 12.35% in 2015 to 14.82% in 2024, reflecting continued improvements in domestic revenue mobilization. This dataset is an essential resource for policymakers, economists, financial institutions, investors, researchers, and international organizations seeking to evaluate fiscal sustainability, taxation efficiency, and government revenue performance across North America. It supports regional and global benchmarking, assessment of tax policy effectiveness, analysis of long-term fiscal trends, and forecasting of government revenues. Additionally, the data contributes to studies on macroeconomic stability, public finance, fiscal resilience, and sustainable economic development by illustrating how taxation supports government expenditure, infrastructure investment, and long-term economic growth across the North American region.
