While taxes help pay for these programs, government spending often exceeds the revenue collected. The US government primarily sells bills, notes, and bonds (collectively called securities) to domestic and foreign individuals, companies, and other governments to cover the gap. This is called public debt. The government also has intragovernmental debt, or money one government sector owes to another. In both cases, the government promises to pay back the original value of the security plus interest to make it worth it for the lender.

The US has accrued debt since its infancy. By 1783, debts from the Revolutionary War totaled $43M. In recent years, the wars in Afghanistan and Iraq, the 2008 recession, and the COVID-19 pandemic have significantly increased the national debt. It temporarily surpassed US GDP in spring 2026, when the country's public debt was estimated to be $31.3T.
