U.S. tax receipts as a percentage of GDP came to about 25.6 percent in 2024, counting collections at every level of government. That figure sits well below the OECD average of 34.1 percent and places the United States in the bottom third of developed economies.1OECD. Revenue Statistics 2025 – United States Federal receipts alone accounted for roughly 17 percent of GDP, with state and local taxes making up the rest.
Federal Receipts Versus the Total U.S. Tax Take
Federal tax receipts equaled about 16.8 percent of GDP in fiscal year 2024 and ticked up to roughly 17.0 percent in fiscal year 2025.2FRED. Federal Receipts as Percent of Gross Domestic Product Over the past 50 years, the federal figure has averaged 17.4 percent, ranging from a high of 20.0 percent in 2000 to a low of 14.5 percent in 2009 and 2010.3Tax Policy Center. What Are the Sources of Revenue for the Federal Government? A single percentage point of GDP works out to hundreds of billions of dollars.
Federal collections are only part of the picture. State and local governments layer on income taxes, sales taxes, property taxes, and fees that add roughly 8 to 9 percentage points on top of the federal share. When the OECD ranks countries, it combines all layers. That combined 25.6 percent is the honest number for international comparison, because many other countries fund at the national level what the U.S. runs through states and cities.
Where Federal Revenue Comes From
Individual income taxes are the largest single source, accounting for about 53 percent of federal revenue so far in fiscal year 2026.4U.S. Treasury Fiscal Data. Government Revenue Payroll taxes for Social Security and Medicare make up roughly another third. Corporate income taxes have run around 9 to 10 percent of total federal receipts in recent years.5Tax Policy Center. How Does the Corporate Income Tax Work? Excise taxes on fuel, tobacco, alcohol, and a handful of other goods cover a much smaller slice.
The mix matters for stability. Payroll taxes are the steadiest stream because wages don’t swing as sharply as profits or capital gains. Individual and corporate income taxes are far more sensitive to conditions in the broader economy, which is why the overall ratio moves year to year even when Congress hasn’t touched the code.
What Moves the Ratio
Two forces do most of the work: legislation and the business cycle.
Major tax bills can shift the ratio by a full percentage point or more in a single year. The 2017 Tax Cuts and Jobs Act lowered the corporate rate from 35 to 21 percent and expanded individual deductions; the federal ratio dropped from 17.1 percent in 2017 to about 16.2 percent in 2018 and 2019 before other factors caught up. Letting temporary provisions expire, or adding new levies, pushes the number the other direction.
Recessions pull the ratio down faster than GDP itself falls. Corporate profits collapse, capital gains dry up, and workers move into lower brackets or lose employment. Because the U.S. income tax is progressive, government revenue shrinks disproportionately when incomes drop. Expansions do the reverse: rising wages push earnings into higher brackets and profitable companies generate more tax liability. That elasticity explains most of the swings visible in the long-run federal series, including the 2000 peak (dot-com capital gains) and the 2009–2010 trough (financial crisis).
How the U.S. Compares to Other Countries
Among OECD nations in 2024, tax-to-GDP ratios ranged from 18.3 percent in Mexico to 45.2 percent in Denmark, with an OECD-wide average of 34.1 percent.6OECD. Revenue Statistics 2025 – Highlights Brochure Several European countries sat well above 40 percent:
- France: 43.5 percent
- Austria: 43.4 percent
- Italy: 42.8 percent
- Belgium: 42.6 percent
- Finland: 42.2 percent
These countries fund universal healthcare, pensions, and childcare through higher tax collection. At 25.6 percent, the United States sat about 8.5 points below the OECD average.1OECD. Revenue Statistics 2025 – United States South Korea was close behind at 25.3 percent, with Chile at 20.5 percent and Colombia at 19.9 percent.6OECD. Revenue Statistics 2025 – Highlights Brochure
Outside the OECD, ratios are often much lower. World Bank data puts India at about 6.7 percent, Bangladesh at 7.6 percent, the Democratic Republic of the Congo at 10.7 percent, and Ethiopia at 3.4 percent.7World Bank. Tax Revenue Percent of GDP Those figures reflect large informal economies and limited administrative capacity rather than a policy choice.
What the Ratio Does and Doesn’t Tell You
A tax-to-GDP ratio is a scale measurement, not a verdict. The U.S. figure lands in roughly the same neighborhood as South Korea’s despite very different government structures, which shows the ratio alone tells you little about how a country organizes its public services. A higher number can mean bigger social programs, more centralized funding, or both; a lower number can mean leaner government or heavier reliance on private spending for the same functions.
The ratio is most useful as a starting point. It sets the scale of what the government is collecting relative to the economy that produces it, and it makes cross-country and cross-decade comparisons possible without getting fooled by inflation or population growth. What the number means for any given fiscal debate depends on what the government is being asked to fund.
