Social Security’s retirement trust fund is projected to run out of reserves in 2033, according to the 2025 Trustees Report.1Social Security Administration. Status of the Social Security and Medicare Programs Actuarial Services 2025 Trustees Report Summary That is not the same as the program shutting down. Payroll taxes keep coming in every pay period, and those taxes alone would cover about 77 percent of the benefits already promised to retirees. So the honest answer to when Social Security will run out of money is that its savings buffer runs dry in 2033, but the checks keep going out at a reduced amount unless Congress changes the law first.
Running Out of Reserves Is Not the Same as Shutting Down
The confusion behind most headlines is a mix-up between the trust fund and the program. They’re not the same thing.
The trust fund is a savings buffer. When Social Security collects more in payroll taxes than it pays out, the surplus is invested in special-issue U.S. Treasury bonds that earn interest and are guaranteed by the federal government.2Social Security Administration. What Are the Trust Funds “Depletion” means those bonds have all been cashed in to cover the gap between what’s coming in and what’s going out. Once they’re gone, Social Security can only spend what it collects in real time.
The program itself has no expiration date. The laws requiring FICA payroll taxes don’t sunset in 2033. As long as people are working and earning wages, money flows into the system and back out to beneficiaries.3Social Security Administration. Actuarial Note Solvency of the Social Security Trust Funds The checking account still has deposits landing in it every two weeks. It just no longer has a savings cushion to draw on when deposits fall short.
One clarification on the two funds you may see mentioned. Social Security has two separate trust funds: Old-Age and Survivors Insurance (OASI) for retirees and their families, and Disability Insurance (DI) for workers with qualifying disabilities.4Office of the Law Revision Counsel. 42 USC 401 Trust Funds The 2033 date is the OASI fund. The disability fund is in far better shape and is projected to stay fully solvent through at least 2099. When the two are combined on paper into a hypothetical single fund (OASDI), depletion moves to 2034.1Social Security Administration. Status of the Social Security and Medicare Programs Actuarial Services 2025 Trustees Report Summary The two funds are legally separate, so one cannot be used to prop up the other without an act of Congress.
What a 23 Percent Cut Would Look Like on Your Check
If Congress does nothing before 2033, the Social Security Administration would be limited to paying out only what it collects in payroll taxes that year. For the retirement fund, that comes to roughly 77 cents on every dollar owed.1Social Security Administration. Status of the Social Security and Medicare Programs Actuarial Services 2025 Trustees Report Summary
In real dollars, the average retirement benefit in January 2026 is about $2,071 per month after the 2.8 percent cost-of-living adjustment.5Social Security Administration. 2026 Cost-of-Living Adjustment COLA Fact Sheet A 23 percent cut would drop that to roughly $1,595. For someone who depends on Social Security for most of their income, that is the difference between covering rent and medication and falling short.
Exactly how a partial-payment scenario would be carried out is not settled. The most commonly discussed option is an across-the-board proportional reduction where every check shrinks by the same percentage. Congress could also protect lower-income beneficiaries while cutting higher earners more, or delay payments rather than reduce them. This is territory the program has never entered, which is part of why the political pressure to act before the deadline is real.
Why the 2033 Date Keeps Moving
The depletion date is not fixed. It shifts every year with updated data on employment, wage growth, birth rates, and immigration. Trustees Reports since 2012 have placed depletion somewhere between 2033 and 2035.3Social Security Administration. Actuarial Note Solvency of the Social Security Trust Funds A stronger economy with higher wages and more workers pushes the date later; a recession or a demographic slowdown pulls it closer. The trustees publish optimistic and pessimistic scenarios alongside their best estimate, so any single-year figure carries a range of uncertainty around it.
Why the Program Is Short on Money in the First Place
Social Security runs on a pay-as-you-go model. Today’s workers fund today’s retirees. Your payroll deductions are not sitting in a personal account waiting for you; they’re going straight out to someone already collecting benefits.
Employees pay 6.2 percent of their wages under FICA, and employers match that for a combined 12.4 percent.6Office of the Law Revision Counsel. 26 USC Subtitle C, Chapter 21, Subchapter A Tax on Employees Self-employed workers pay the full 12.4 percent themselves. These rates have been unchanged since 1990. The tax also stops at a cap on annual earnings, which for 2026 is $184,500, so someone earning $184,500 and someone earning $5 million pay the same maximum employee-side contribution of $11,439.7Social Security Administration. Contribution and Benefit Base
The system works fine when there are enough workers per retiree. The problem is demographic. Baby boomers are retiring, birth rates are falling, and the ratio of workers to beneficiaries has been declining for decades. That imbalance is what has been drawing down the reserves.
Will Congress Fix It Before 2033?
Social Security has been here before. In the early 1980s, the program was within months of being unable to mail checks. Congress passed the Social Security Amendments of 1983, a bipartisan package built on the Greenspan Commission’s recommendations.8Social Security Administration. Summary of P.L. 98-21 H.R. 1900 Social Security Amendments of 1983 That law brought new federal employees into the system, taxed a portion of benefits for higher earners, and began the gradual increase of the full retirement age from 65 to 67 that is still being phased in. Those changes extended solvency by decades.
The actuaries at Social Security have already scored dozens of specific fixes for the current shortfall, which stands at 3.82 percent of taxable payroll.9Social Security Administration. Summary of Provisions That Would Change the Social Security Program The main categories on the table:
- Raising the combined payroll tax rate from 12.4 percent to 16.4 percent would close 102 percent of the shortfall.
- Applying the full 12.4 percent tax to all earnings with no cap would close about 67 percent. A version that only taxes earnings above $250,000 would close about 65 percent.
- Gradually raising the full retirement age to 69 would close about 36 percent. Raising it to 70 while also lifting the earliest eligibility age from 62 to 64 would close about 44 percent.
- Cutting the annual cost-of-living adjustment by one percentage point would close 51 percent, though the reduction compounds and hits current retirees hardest.
No single lever fixes this painlessly. Any serious solution will almost certainly combine revenue increases with benefit adjustments, the way the 1983 amendments did. One current bill, the Social Security Expansion Act, would apply payroll taxes on income above $250,000 while also raising benefits by $2,400 per year; sponsors say it would extend solvency for 75 years.9Social Security Administration. Summary of Provisions That Would Change the Social Security Program Whether that particular bill moves or not, the arithmetic is public and the options are known.
Medicare Faces the Same Deadline
Social Security isn’t the only federal trust fund on this timeline. Medicare’s Hospital Insurance (Part A) Trust Fund is also projected to be exhausted in 2033. After depletion, Part A could cover about 89 percent of scheduled hospital benefits from ongoing tax revenue.1Social Security Administration.

For your own planning, treat 2033 as a date to prepare for rather than fear. Benefits will not disappear that year. But a 23 percent haircut on the retirement side, paired with an 11 percent haircut on hospital coverage, is what the current law produces if nothing changes. Building outside savings and income sources into your retirement plan is what the trustees’ own numbers point toward, regardless of what Congress eventually does.
