What Do Your Taxes Pay For? Where Federal Tax Dollars Actually Go
Taxes are one of the biggest budget items for most taxpayers, yet many people have little idea what they’re actually getting for their money.
Americans continue to spend a substantial share of their income on taxes each year — often working well into the spring before earning enough to cover their full tax bill. So what does all that money actually fund?
Where Does Tax Money Go? A Breakdown of Federal Spending
Federal spending totaled roughly $6.8 trillion in fiscal year 2024, the most recent full year of data available. Here’s how that spending breaks down by major category:
- Health programs (including Medicare) — approximately 27% of the federal budget
- Social Security — approximately 21%
- National defense — approximately 13%
- Interest on the national debt — approximately 13%
Together, these four categories account for nearly three-quarters of all federal spending.
How Are Tax Dollars Spent? The Biggest Categories Explained
Social Security
Social Security remains one of the single largest line items in the federal budget, providing retirement, disability, and survivor benefits to millions of Americans.
Health Programs and Medicare
Health-related spending — primarily Medicare, along with related health programs — represents the largest overall category of federal spending, reflecting the size and cost of the nation’s healthcare and retirement-age medical coverage systems.
National Defense
Defense and related spending continues to represent a significant share of the federal budget, funding military operations and national security programs.
Interest on the National Debt
Interest payments on the national debt have become an increasingly significant portion of federal spending, now roughly matching the share spent on national defense.
