The Congressional Budget Office (CBO) announced Monday that the projected federal deficit for fiscal year 2026 has risen to $2.1 trillion. This figure is $200 billion higher than the agency’s previous estimate of $1.9 trillion issued in February.
The CBO, a nonpartisan federal agency that provides budget and economic information to Congress, attributed the increase primarily to a decline in projected tariff revenue. According to the report, the U.S. Supreme Court struck down levies in February that had been imposed by President Trump under the International Emergency Economic Powers Act. While the administration has since implemented new import taxes under the Trade Act of 1974, the CBO estimated that total customs duties for 2026 will be approximately $250 billion lower than previously expected.
Federal outlays through the first 10 months of fiscal 2026 reached more than $6.2 trillion, an increase of $209 billion over the same period in fiscal 2025 after adjusting for payment timing. The CBO noted that 86 percent of the spending increase was driven by Social Security, Medicare, and Medicaid. These increases were attributed to a larger number of Social Security beneficiaries, higher Medicare enrollment, and rising costs per Medicaid enrollee.
The scale of the deficit increase represents a roughly 10 percent rise over the February estimate, contributing to a total projected shortfall that exceeds $6,000 per American resident for the 2026 fiscal year alone. Small-business owners and consumers may see the effects through trade policy, as the CBO expects $250 billion less in tariff collections than originally anticipated due to the Supreme Court's rejection of certain emergency levies. While federal revenues increased by $139 billion compared to last year, the $308 billion increase in outlays indicates that spending growth continues to outpace revenue growth.
The report sets a baseline for ongoing legislative debates regarding the sustainability of social programs. Lawmakers have introduced competing proposals to address the funding gap, including a bipartisan plan from Sens. Bill Cassidy (R-La.) and Tim Kaine (D-Va.) to invest $1.5 trillion into a fund to cover unfunded liabilities. Other proposals include lifting the cap on payroll taxes for higher earners. The next significant milestones for these fiscal projections include the end of the 2026 fiscal year and the 2032 deadline for the Social Security trust fund’s projected inability to pay full benefits.
