New deductions reduce federal revenue, cutting Medicare coverage to 89% of Part A costs at depletion while accelerating insolvency.
The One Big Beautiful Bill Act has accelerated Medicare’s trust fund depletion by three months to mid-2033, when it will cover only 89% of Part A hospital costs. The shortfall stems from a $6,000 senior tax deduction shielding 88% of Social Security recipients from federal taxes on benefits, reducing program revenue.
Prior projections had the trust fund exhausting in late 2033, with full coverage until then. The OBBBA increased the shortfall by 0.09% of payroll, further straining solvency. Medicare Part A, which covers inpatient hospital stays, relies solely on the trust fund for funding.
The tax breaks, while boosting seniors’ take-home income, may lead to higher long-term costs for retirees as program finances deteriorate.
