Introduction
The latest Social Security and Medicare Trustees reports show that the nation’s two largest entitlement programs are moving closer to depletion, narrowing the window for Congress to act before automatic benefit and provider-payment reductions take effect.
The Old-Age and Survivors Insurance (OASI) Trust Fund, which finances Social Security retirement and survivors benefits, is now projected to be depleted in the fourth quarter of 2032, one quarter earlier than projected in last year’s report. This means that sometime around October 2032, continuing program income will be sufficient to pay only 78% of scheduled benefits, resulting in an automatic 22% benefit cut absent reform.
Congress still has time to strengthen these programs, but that window is narrowing. Acting sooner would give lawmakers more options, allow reforms to be phased in gradually, and reduce the risk of sudden benefit reductions for retirees or payment disruptions for Medicare providers. Waiting until trust fund depletion is imminent would leave fewer choices and shift a larger burden onto workers, beneficiaries, providers, and taxpayers.
A responsible reform agenda should protect current beneficiaries, improve long-term solvency, and pair budgetary discipline with pro-growth policies that expand employment, wages, and the tax base.
Background
Social Security is often discussed as a single program, but it is financed through separate trust funds for retirement, survivors’ benefits, and disability benefits. The OASI Trust Fund finances Social Security retirement and survivors benefits, which make up the largest share of Social Security payments. It is funded primarily through a 12.2% payroll tax paid by workers and employers under the Federal Insurance Contributions Act (FICA) and the Self-Employment Contributions Act (SECA).
The Medicare Hospital Insurance (HI) Trust Fund, also known as Medicare Part A, finances inpatient hospital care, skilled nursing facilities, home health care, hospice services, and the administrative costs associated with the Medicare program.
Each year, the Trustees provide Congress with a detailed, updated accounting of these trust funds. These reports are an early warning system: they show when dedicated revenues and trust fund reserves will no longer be sufficient to pay full scheduled benefits under current law.
The Findings in the Trustees’ Report
The 2026 reports show that both programs remain on an unsustainable path.
For Social Security, the OASI Trust Fund is projected to deplete in 2032. Once that occurs, the Social Security Administration would be unable to pay full scheduled retirement and survivors benefits without legislative changes. Continuing revenue would be sufficient to cover only 78% of scheduled OASI benefits, leaving a 22% financing shortfall.
For an average retiree receiving $2,071 per month in 2026, a 22% reduction would equal over $5000 per year. In some states, the cuts would be even steeper. The Committee for Responsible Federal Budget reported that the average monthly benefit cut would surpass $500 in 29 states and the total benefit cut would exceed more than 1% of Gross Domestic Product in 40 states.
For Medicare, depletion of the HI Trust Fund in 2033 would leave it unable to fully finance scheduled benefits. According to the Trustees, continuing program income would still cover 89% of scheduled Hospital Insurance benefits after depletion, leaving an 11% percent shortfall. Because Medicare Part A pays hospitals, skilled nursing facilities, hospice, and some home health services, that shortfall would primarily affect payments to providers and could create access-to-care concerns if Congress fails to act.
Why the Outlook Worsened
The Trustees identified several factors behind the weaker Social Security outlook.
- Lower fertility rates: The assumed long-term fertility rate was lowered from 1.9 to 1.75 children, suggesting a smaller future workforce and lower payroll tax revenue.
- Lower Immigration Projections: With deportations, tighter visa rules, and changing immigration laws, projected immigration levels were revised downward. Together, these two demographics shifts are expected to reduce the future workforce and projected GDP over the long-term.
- One Big Beautiful Bill Act: Signed on July 4, 2025, the law created a temporary Senior Tax Deduction (also called the “No Tax on Social Security”) for tax years 2025 through 2028. It allows an additional below-the-line deduction of up to $6,000 for single filers and $12,000 for married couples if both are age 65 or older (subject to income phaseouts). Because federal income taxes on Social Security benefits are credited to the trust funds, reductions in taxable benefit income also reduce trust fund revenue.
For Medicare, higher assumed usage of certain medical services increased projected costs for the Hospital Insurance Trust Fund. The same reduction in benefit taxation revenue that affected Social Security also reduced projected Medicare HI Trust Fund revenue.
Comparison of 2025 and 2026 Trustees Reports
The 2025 and 2026 trustees report tell a consistent story of depletion across both Social Security and Medicare. For Social Security's OASI Trust Fund, the depletion date moved from the first quarter of 2033 in last year's report to the fourth quarter of 2032 this year. Medicare's Hospital Insurance Trust Fund followed the same downward trajectory on a smaller scale, with its projected depletion date from the third quarter of 2033 to the second quarter of 2033.
Each year, the Trustees project the future cost and income for each of the trust funds for the next 75 years. The SSA revised its fertility and immigration projections downward, driving the 75-year unfunded obligation from $26.1 trillion to $30.3 trillion. The $4.2 trillion increase—about 16% in one year—shows how significantly demographic, economic, and legislative changes can affect the program’s long-term outlook.
The Secrets Buried in the Trustee Report
On June 10, the Cato Institute published a report suggesting that the Trustees are likely understating the shortfall. The official report projects insolvency in 2032 with a $30 trillion unfunded obligation. However, Cato argues the real number is closer to $33 trillion after excluding the trust fund reserves.
The gap may be even wider on the fertility front. The Trustees assume fertility will recover to 1.75 children per woman by 2045 but the Census Bureau projects 1.61 and CBO projects 1.53. Since fewer births mean a smaller future workforce and lower payroll tax revenue, more conservative fertility assumptions point to a shortfall of $35 to $36 trillion, meaning the trustees may be underestimating the shortfall by 6% to 9%.
Conclusion
The 2026 Trustees Reports reinforce a basic fiscal reality: Social Security and Medicare are approaching depletion, and delay will only make the eventual choices more painful.
The Trustees have therefore issued another warning. The sooner reforms are enacted, the less costly they will be. Congress should not wait for insolvency to force its hand.
