This rapid deterioration of Medicare’s financial solvency represents a stark drop from the CBO’s previous estimate, which was published just last year, in March 2025. The dramatically shortened timeline means future retirees could face significant cuts to vital health care services far sooner than previously anticipated. As required by the Deficit Control Act, CBO Director Phillip Swagel noted the projections reflect the assumption benefits would be paid as scheduled even after the HI trust fund was exhausted.

The primary culprit for this accelerated depletion is a sharp reduction in the fund’s projected income, heavily driven by legislation passed over the last year. Specifically, the 2025 reconciliation act (Public Law 119-21, more commonly known as the One Big Beautiful Bill Act) significantly reduced the revenues the trust fund normally receives from taxing Social Security benefits. This legislation lowered tax rates and established a temporary deduction for taxpayers age 65 or older. Consequently, this major policy shift enacted during the Trump administration has directly contributed to starving the Medicare safety net of critical future funding.
