Revenue Is Up in FY 2026

Federal revenue collections rose by $143 billion (4 percent) during the first nine months of FY 2026 compared to last year. Individual income tax receipts increased by $136 billion (7 percent) and payroll tax collections rose by $34 billion (3 percent) due to rising wages and salaries. Corporate income tax receipts declined by $87 billion (24 percent) due to the One Big Beautiful Bill’s business tax changes, including larger tax deductions for certain business investments. Customs duties rose by $55 billion (51 percent) due to tariff changes made through executive action. Notably, customs duties declined drastically in May and June as the federal government issued about $70 billion of the $166 billion total eligible tariff refunds to businesses that paid tariffs imposed under the International Emergency Economic Powers Act, which the Supreme Court ruled was illegal. Estate and gift taxes increased by $8 billion (35 percent), excise tax collections remained flat at $75 billion, and other sources of revenue declined by $3 billion (11 percent).

Spending Is Up in FY 2026

Federal spending rose by $172 billion (3 percent) during the first nine months of FY 2026 compared to the corresponding period last year. Social Security spending increased by $63 billion (5 percent) due to increases in average monthly benefits and the number of beneficiaries enrolled in the program. Medicare spending rose by $57 billion (8 percent) due to higher enrollment and payment rates for services, and Medicaid spending increased by $49 billion (10 percent) because of higher per-enrollee costs. Other health spending, including on the Children’s Health Insurance Program and Affordable Care Act premium tax credits, declined by $2 billion (1 percent).

National defense spending increased by $31 billion (4 percent) due to higher spending on military personnel and research and development. Spending on veterans benefits and services rose by $27 billion (10 percent) because more people received benefits and spending per beneficiary rose. Spending on income security programs, including the Supplemental Nutrition Assistance Program, Supplemental Security Income, and Temporary Assistance for Needy Families, fell by $11 billion (2 percent) in part because of the One Big Beautiful Bill’s reforms to certain income security programs.

Interest payments on the national debt increased by $78 billion (10 percent) because the debt was larger and long-term interest rates were higher. Net interest remains the second-largest government expenditure behind Social Security.\

The National Debt Is Unsustainable

At the end of June 2026, federal debt held by the public totaled $31.7 trillion. This was $2.7 trillion higher than the $29.0 trillion debt at the end of June 2025.

Since May of 2019 – before the fiscal impact of the COVID-19 pandemic really materialized – the national debt has nearly doubled and is projected to continue to rise over both the short- and long-term.
