If Social Security runs out of money, your check shrinks; it does not disappear. The retirement trust fund is projected to be depleted in 2033, but payroll taxes keep flowing in from current workers, and that revenue alone would cover roughly 77 cents of every dollar in scheduled retirement benefits.1Social Security Administration. A Summary of the 2025 Annual Reports More than 70 million Americans currently receive Social Security, and the program would keep paying the majority of what it owes even if Congress does nothing.2Social Security Administration. Monthly Statistical Snapshot, February 2026 That’s a painful automatic cut, not an extinction event.
When the Trust Fund Is Projected to Run Dry
The Social Security Trustees publish an annual projection of when each trust fund’s reserves will be exhausted. The 2025 report puts the Old-Age and Survivors Insurance (OASI) Trust Fund, which pays retirement and survivor benefits, on track for depletion in 2033. The combined OASI and Disability Insurance funds together would run dry in 2034, a year earlier than the previous estimate.1Social Security Administration. A Summary of the 2025 Annual Reports
The split between the two funds matters for what you’re planning around. The Disability Insurance Trust Fund is projected to stay solvent through at least 2099.1Social Security Administration. A Summary of the 2025 Annual Reports The retirement side is where the pressure is. If you’re focused on your own retirement check, 2033 is the date to watch. The projection shifts a little each year with changes in economic growth, wages, birth rates, and immigration.
What “Running Out of Money” Actually Means
The phrase is misleading, because Social Security never stops collecting revenue. Workers and employers pay in every pay period, and that flow continues no matter what happens to the trust fund. Depletion means the program’s savings account hits zero and it can only spend what comes in the door that year.
Right now, Social Security draws on three sources to pay benefits: current payroll tax revenue, interest earned on the special Treasury bonds held by the trust funds, and the reserves themselves.3Social Security Administration. Frequently Asked Questions About the Social Security Trust Funds Once the reserves are gone, only current tax revenue remains. Benefits have to be cut to match.
How Much Smaller Your Check Would Be
The 2025 Trustees Report projects that at OASI depletion in 2033, continuing tax income would cover 77% of scheduled retirement benefits. For the combined trust funds at their 2034 depletion date, the figure is 81%.1Social Security Administration. A Summary of the 2025 Annual Reports Because the Social Security Administration has no authority to borrow or run a deficit, the cut would likely be across the board.
In dollars: the average monthly retirement benefit in 2026 is $2,071.4Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet A 23% reduction takes that to roughly $1,595 a month. For anyone whose Social Security makes up half or more of retirement income, that shortfall is severe. And without legislative action, the percentage isn’t likely to improve later, because the ratio of workers paying in to beneficiaries drawing benefits keeps dropping. In 2026 there are about 2.6 workers per beneficiary, and that number is still falling.5Social Security Administration. Covered Workers and Beneficiaries – 2025 OASDI Trustees Report
Why You Can’t Sue for the Full Amount
Many people assume that decades of paying in give them a contractual right to their full benefit. The law is less reassuring than that.
The Social Security Act says eligible individuals “shall be entitled” to old-age insurance benefits.6Office of the Law Revision Counsel. United States Code Title 42 – Section 402 But in Flemming v. Nestor (1960), the Supreme Court held that Social Security benefits are not accrued property rights. The Court called them a non-contractual government benefit that Congress can modify or reduce. Workers who paid in for years don’t have the kind of contractual claim they would have with a private pension.
Federal law also prohibits any government agency from spending more than the funds available to it.7Office of the Law Revision Counsel. United States Code Title 31 – Section 1341 Limitations on Expending and Obligating Amounts Once the trust fund is depleted, the Social Security Administration cannot legally pay out more than it takes in. Those two rules collide: one says you’re entitled to benefits, the other says the agency can’t spend money it doesn’t have. No court has resolved what happens when both apply at once, because Congress has never let the situation get that far.
How a Cut Would Ripple Through Your Budget
Medicare Premiums Take a Bigger Bite
Most people on Medicare have their Part B premium deducted automatically from their Social Security payment.8Medicare. How to Pay Part A and Part B Premiums The standard Part B premium in 2026 is $202.90 a month.9CMS. 2026 Medicare Parts A and B Premiums and Deductibles If your Social Security check dropped 23% overnight, the premium wouldn’t change, but it would consume a much larger share of what’s left.
A federal “hold harmless” rule normally keeps your net Social Security payment from shrinking year over year because of a Medicare premium increase that outpaces your cost-of-living adjustment. That rule was designed for ordinary premium fluctuations, not a sudden benefit cut driven by trust fund depletion. How it would interact with an across-the-board reduction is genuinely uncharted.
Taxes on Your Benefits
Up to 85% of your Social Security can be subject to federal income tax, depending on your “combined income,” which is your adjusted gross income plus tax-exempt interest plus half your Social Security benefits.10Social Security Administration. Must I Pay Taxes on Social Security Benefits The thresholds are $25,000 for single filers and $32,000 for joint filers, with a higher tier at $34,000 and $44,000.11Office of the Law Revision Counsel. United States Code Title 26 – Section 86 Social Security and Tier 1 Railroad Retirement Benefits
Those thresholds have not been adjusted for inflation since they were set in 1983, so more retirees cross them every year. If benefits were cut 23%, the taxable portion of the benefit would fall too, which is a small silver lining. The reduced check still hurts far more than the modest tax savings help.
Congress Has Fixed This Before
Social Security faced a nearly identical crisis in the early 1980s. The trust funds were months from being unable to cover full benefits. A bipartisan commission led by Alan Greenspan recommended a package of changes, and Congress passed the Social Security Amendments of 1983 with broad support.
That package used every tool available. Scheduled payroll tax increases were accelerated. A portion of benefits became subject to federal income tax for the first time. The annual cost-of-living adjustment was delayed by six months. New federal employees were brought into the system, expanding the contribution base. And the full retirement age was gradually raised from 65 to 67, phased in over decades starting with workers who turned 62 in 2000.12Congress.gov. S.1 – Social Security Amendments of 1983 98th Congress (1983-1984)
The 1983 fix held for about 50 years. The current shortfall is larger, but the menu of options is the same.
The Levers on the Table
The Social Security Administration tracks reform proposals as they are introduced in Congress.13Social Security Administration. Proposals to Change Social Security The main options:
- Raise the payroll tax rate. Even a modest increase split between workers and employers generates substantial revenue.
- Lift or eliminate the wage cap. In 2026, only the first $184,500 of earnings is subject to Social Security tax; removing that ceiling would close a large share of the gap on its own.14Social Security Administration. What Is the Current Maximum Amount of Taxable Earnings for Social Security
- Raise the full retirement age. It’s currently 67 for anyone born in 1960 or later; pushing it to 68 or 69 reduces lifetime benefits.
- Adjust the benefit formula, or tie cost-of-living adjustments to a slower measure of inflation. Either lowers future payouts.
- Means-test benefits by reducing payments to higher-income retirees.
No single lever is enough. The 1983 reforms combined revenue increases and benefit adjustments, and any future deal will almost certainly require the same mix. Every year Congress waits, the eventual adjustment gets steeper, whether through higher taxes, lower benefits, or both. In 1983, Congress acted only when the trust fund was within months of depletion. Whether that pattern repeats is the open question.
