deficit (surplus) - The amount by which outlays exceed receipts in a given fiscal period. (A surplus would be the amount by which receipts exceed outlays.) US Senate Glossary
In FY 2026 the federal deficit was $1.99 trillion. But the gross federal debt increased by $2.80 trillion. Here is why.
This year, FY 2027, the federal government in its latest budget has estimated that the deficit will be $2.17 trillion.
Here is the federal deficit by year for the last decade:

The federal debt increases each year by more than the deficit. For FY 2027 the federal budget estimates that the federal debt will increase by about $0.62 trillion. That’s about $-1.55 trillion more than the official “deficit.” See Federal Debt.
But there’s more. There is the increase in in the “agency debt” of government-sponsored enterprises like the Federal National Mortgage Association. And there is the implied deficit from unfunded liabilities like Social Security and Medicare. See chart of latest Long-term Budget Outlook from the Congressional Budget Office.

Chart D.03f: Federal Deficits since 1900
The two major peaks of the federal deficit in the 20th century occurred during World War I and World War II.
Deficits increased steadily from the 1960s through the early 1990s, and then declined rapidly for the remainder of the 1990s.
Federal deficits increased in the early 2000s, and went over 10 percent of GDP in the aftermath of the financial crisis of 2008.
In the recovery from the Crash of 2008 deficits slowly reduced to 3 percent of GDP in 2015 and then started increasing again.
In the COVID crisis of 2020 the federal deficit ballooned to over 15 percent of GDP.

On October 15, 2026, the US Treasury reported in its Monthly Treasury Statement (and xlsx) for September that the federal deficit for FY 2025 ending September 30, 2026, was $1,99 billion. Here are the numbers, including total receipts, total outlays, and deficit compared with the numbers projected in the FY 2026 federal budget published in February 2025:
| Federal Finances FY 2026 Outcomes | |||
|---|---|---|---|
| Budget billions | Outcome billions | ||
| Receipts | $5,873 | $5,403 | |
| Outlays | $7,419 | $7,396 | |
| Deficit | $1,547 | $1,993 | |
The Monthly Treasury Statement includes "Table 4: Receipts of the United States Government, September 2026 and Other Periods." This table of receipts by source is used for usgovernmentspending.com to post details of federal receipt actuals for FY 2025. usdgovernmentspending.com obtains the data for outlays and receipts from apis at fiscaldata.treasury.gov.
This MTS report on FY 2026 actuals is a problem for usgovernmentspending.com because this site uses Historical Table 3.2--Outlays by Function and Subfunction from the Budget of the United States as its basic source for federal subfunction outlays. But the Monthly Treasury Statement only includes "Table 9. Summary of Receipts by Source, and Outlays by Function of the U.S. Government, September 2025 and Other Periods". Subfunction amounts don't get reported until the FY28 budget in February 2027. Until then usgovernmentspending.com estimates actual outlays by "subfunction" for FY 2026 by factoring subfunction budgeted amounts for FY26 by the ratio between relevant actual and budgeted "function" amounts where actual outlays by subfunction cannot be gleaned from the Monthly Treasury Statement.
