The Social Security trust fund is projected to become depleted in 2033, according to the latest Trustees Report, leaving the program able to pay only 77 percent of scheduled benefits — a 23 percent reduction — unless Congress acts to shore up finances. The Old-Age and Survivors Insurance (OASI) Trust Fund faces the shortfall unchanged from last year’s projection, while the combined OASI and Disability Insurance funds would run dry one year sooner than previously estimated.
Quick Facts
- OASI Trust Fund reserves depleted in 2033, unchanged from 2024 report
- 77 percent of scheduled benefits payable at depletion, a 23 percent reduction
- Combined OASDI reserves projected to deplete in 2034, one year sooner than last year
- 81 percent of combined benefits payable if OASI and DI funds were merged at depletion
What the 2025 Trustees Report Reveals
The Social Security Board of Trustees released its annual financial assessment in June 2025, projecting the long-range outlook for both Social Security and Medicare. For the social security trust fund, the findings underscore persistent financing challenges. The OASI Trust Fund, which pays retirement and survivor benefits to 60.1 million people as of the end of 2024, will exhaust its reserves in 2033 if no legislative changes occur. At that point, payroll tax income alone will cover only 77 percent of obligations, forcing a mandatory across-the-board benefit reduction unless Congress intervenes.
The report notes that the OASI Trust Fund has been drawing down reserves since 2021 to finance benefits. In 2024, the fund’s costs of $1.327 trillion exceeded income by $103.2 billion. This annual deficit is projected to continue and worsen, accelerating the path to depletion. The Disability Insurance (DI) Trust Fund, by contrast, remains solvent through at least 2099 under current law.

Why the Depletion Date Changed
The combined OASDI projection worsened this year, advancing the hypothetical depletion date from 2035 (in last year’s report) to 2034. Three major factors drove this change. First, the Social Security Fairness Act, enacted in January 2025, repealed the Windfall Elimination and Government Pension Offset provisions, increasing projected benefits for some workers. Second, the Trustees extended the assumed recovery period from historically low fertility rates by 10 years, now reaching the ultimate rate in 2050 rather than 2040. Third, the long-range ratio of labor compensation to GDP was lowered based on recent data.
These demographic and economic adjustments mean that the social security trust fund faces larger projected deficits across all future years. The average annual deficit over the 75-year projection period is about 0.28 percentage point higher than in last year’s report, according to the Trustees.
What Happens at Depletion and Options Ahead
When the OASI Trust Fund reserves are exhausted in 2033, the program will automatically shift to a pay-as-you-go system, relying entirely on incoming payroll taxes. This would trigger a 23 percent immediate reduction in all retirement and survivor benefits unless Congress passes legislation to address the shortfall. The reduction would affect all beneficiaries equally — current retirees and future claimants alike.
The Trustees emphasize that lawmakers have many options to address the financing gap. These range from increasing the payroll tax rate, raising the taxable earnings cap, adjusting benefit formulas, gradually raising the full retirement age, or some combination of these measures. The report stresses that taking action sooner rather than later would allow Congress to phase in changes gradually and give workers and beneficiaries time to adjust their expectations. Delaying action would require more abrupt and larger changes to either revenues or benefits.
