The Treasury reported a $1.99 trillion deficit for fiscal 2026, underscoring heavy borrowing and a path toward a record debt load in the coming years. That is about 12% wider than last year's $1.78 trillion gap.
Spending climbed 6% to $7.4 trillion, with revenue up 3% to $5.4 trillion. In September alone, the government spent $27 billion more than it took in.
Higher yields and a bigger debt stock made interest a major pressure point. Net interest rose by $81.4 billion to an all time high of $1.05 trillion, placing debt service among the government's three largest expenses.
Social Security remained the largest line item, with outlays increasing $86.4 billion to $1.67 trillion. Medicare outlays climbed by $76 billion, reaching $1.07 trillion.
Scott Bessent, the Treasury Secretary, cited tariff refund payments as an additional driver of the widening gap. Those refunds follow the Supreme Court's February ruling that invalidated most of President Donald Trump's second term tariff increases. The administration is working on new tariff measures via other legislation.

This is the fourth year with a deficit near $2 trillion, about 6% of GDP, which is historically high alongside relatively low unemployment. The prior year's improvement was largely accounting based, after the 2025 Republican tax act tightened student loan limits and Treasury recorded that as lower 2025 spending.
On the revenue side, the Treasury took in an additional $189 billion in individual income taxes in 2026. Meanwhile, corporate income tax revenue dropped by over $70 billion following the 2025 tax bill's extension of many cuts and creation of new deductions for businesses. One measure of public debt outstanding topped a record $40 trillion last month.
Bessent says the debt path can be bent down quickly, citing faster trend growth as artificial intelligence lifts productivity. Skeptics are vocal. IMF Managing Director Kristalina Georgieva said on Oct. 14 that "growth, of course, helps but it cannot deliver fast enough the necessary adjustments." David Zervos, a counselor to Bessent, replied on CNBC that the IMF has had "messy" forecasts in the past.
That same day, ECB chief Christine Lagarde - Georgieva's predecessor - said deficits of the kind the U.S. faces are something any nation in that position must address. And on Oct. 8, CBO Director Phillip Swagel said growth by itself is not a plausible way to stabilize U.S. debt levels. The CBO warned in February that debt relative to GDP is on track to surpass the 1946 peak of 106% by 2030.
Policy is the swing factor from here. Bessent plans to introduce a fiscal consolidation plan during the lame-duck session in the event Republicans relinquish control of either chamber of Congress. Concurrently, Trump's wishlist includes about a $500 billion boost for defense and, should Republicans keep both chambers in next month's midterm elections, $5,000 checks to every American.
In plain English: a record $1.05 trillion interest tab, rising entitlement costs, tariff refund outlays tied to the February ruling, and weaker corporate tax receipts all point to a deficit that sticks near 6% of GDP without a policy course change. That backdrop matters for rates, Treasury supply, and risk appetite across stocks and credit.
