Treasury closed the books on fiscal year 2026 on September 30. Here is what its Monthly Treasury Statement and Debt to the Penny data show, applied to one household’s federal taxes, using the government’s own figures and no forecasts.
Take a household that paid $8,000 in federal income tax and $5,000 in Social Security and Medicare tax withheld from wages in fiscal year 2026 (October 1, 2025 to September 30, 2026): $13,000 in total. Employee payroll tax is 6.2% for Social Security and 1.45% for Medicare (IRS Topic 751), so of the $5,000, $4,052 went to Social Security and $948 to Medicare.
Net outlays were $7,395.8 billion, up from $7,010.0 billion in FY2025. The ten largest functions, with this household’s $13,000 split in proportion and the amount per U.S. resident:
| Function | FY2026 outlays | Share | Household’s $13,000 | Per resident |
|---|---|---|---|---|
| Social Security | $1,667.1 billion | 22.5% | $2,930 | $4,878 |
| Medicare | $1,072.6 billion | 14.5% | $1,885 | $3,138 |
| Net Interest | $1,051.8 billion | 14.2% | $1,849 | $3,077 |
| Health | $1,025.6 billion | 13.9% | $1,803 | $3,001 |
| National Defense | $965.2 billion | 13.1% | $1,697 | $2,824 |
| Income Security | $694.2 billion | 9.4% | $1,220 | $2,031 |
| Veterans Benefits and Services | $416.2 billion | 5.6% | $732 | $1,218 |
| Transportation | $142.9 billion | 1.9% | $251 | $418 |
| Administration of Justice | $109.9 billion | 1.5% | $193 | $322 |
| Education, Training, Employment, and Social Services | $107.6 billion | 1.5% | $189 | $315 |
Per resident uses the Census Bureau’s 341,784,857 residents on July 1, 2025. Total outlays were $21,639 per resident. The federal tax receipt calculator splits any amount the same way, by FY2026 or FY2025 shares.
The proportional split above treats every tax dollar alike. Payroll taxes, though, are credited to the Social Security and Medicare trust funds. Sending this household’s $5,000 there and spreading only the $8,000 of income tax across the other functions gives $4,052 for Social Security, $948 for Medicare and $1,807 for net interest, instead of $2,930, $1,885 and $1,849. Both are accounting views of the same Treasury table.
Receipts were $5,403.3 billion ($15,809 per resident): individual income taxes $2,845.5 billion, employment and retirement taxes $1,754.3 billion, and the rest from corporate income taxes, customs duties, excise and other taxes. Outlays exceeded receipts by $1,992.5 billion, so receipts covered 73.1% of spending. In FY2025 the gap was $1,775.4 billion. Per resident, the FY2026 deficit was $5,830.
Treasury’s Debt to the Penny reported total public debt outstanding of $37.64 trillion on September 30, 2025 and $40.17 trillion on September 30, 2026, an increase of $2,534.3 billion. Debt held by the public rose $2,147.2 billion and intragovernmental holdings rose $387.0 billion. On October 20, 2026 the total was $40,439,546,016,039.08, which is $118,318.72 per resident. The national debt calculator divides the latest figure by population or by household.
Net interest was $1,051.8 billion in FY2026, up from $970.4 billion in FY2025, or $3,077 per resident. That is 14.2% of outlays, just below Medicare (14.5%) and above health (13.9%) and national defense (13.1%).
These are cash outlays and receipts for a completed fiscal year, not budgets, appropriations or projections. Per-resident figures are averages for scale: nobody receives or owes them individually. A household’s tax is not earmarked to particular programs apart from payroll taxes to their trust funds, and the borrowed share means spending is larger than any split of tax payments shows.
