The Congressional Budget Office's 2032 Projection

The Congressional Budget Office (CBO) projects that Social Security's combined trust funds—the Old-Age and Survivors Insurance (OASI) fund and the Disability Insurance (DI) fund—will be depleted around 2032 to 2034, depending on which report year you read and economic conditions that year. When a trust fund is depleted, it does not mean Social Security stops; it means the program can only pay benefits from incoming payroll taxes, which would cover roughly 80 percent of scheduled benefits at that point.

This projection comes from the CBO's regular analysis of Social Security's finances, which it publishes alongside reports from the program's own trustees. The CBO uses different economic assumptions than the trustees do—different inflation rates, wage growth, and life expectancy estimates—so its depletion date sometimes falls earlier or later than the trustees' estimate. The CBO's most recent long-range projections place depletion in the early 2030s, though the exact year shifts as new data arrives each year.

The CBO does not recommend policy changes; it only measures what current law would produce. Congress uses these projections to decide whether to change payroll tax rates, benefit formulas, the retirement age, or some combination of those three.

Key Takeaways

  • The CBO projects Social Security's trust funds will be depleted sometime between 2032 and 2034, after which the program can pay only the portion of benefits covered by incoming payroll taxes.
  • A depleted trust fund does not mean Social Security disappears; it means benefit payments would drop to roughly 80 percent of the scheduled amount unless Congress changes the law.
  • The CBO's depletion date differs from the Social Security trustees' estimate because the two organizations use different assumptions about inflation, wage growth, and life expectancy.
  • The CBO publishes projections but does not recommend which policy changes Congress should make to address the shortfall.

How the CBO Calculates the Depletion Date

The CBO starts with the current balance in both trust funds combined, then projects how much money flows in from payroll taxes each year and how much flows out in benefits. The difference between inflows and outflows either adds to or subtracts from the trust fund balance. When the balance reaches zero, the fund is depleted.

To make these projections, the CBO estimates future payroll tax revenue based on assumptions about wage growth, employment rates, and the size of the workforce. It estimates benefit payments based on assumptions about life expectancy, the number of people claiming at each age, and the average benefit amount. Small changes in any of these assumptions can shift the depletion date by a year or two.

The CBO updates its projections regularly. Economic recessions, changes in mortality rates, or shifts in when people claim benefits can all move the projected depletion date forward or backward. A year of stronger-than-expected wage growth might push depletion out by a few months; a year of higher-than-expected life expectancy might pull it in.

What Happens When a Trust Fund Depletes

When the trust fund balance reaches zero, Social Security does not stop paying benefits. Instead, the program collects payroll taxes from current workers and pays current beneficiaries with that money when ready. This is called pay-as-you-go financing, and it is how Social Security has always worked in principle—the trust funds are a buffer, not a savings account.

The problem is that payroll tax revenue alone will not be enough to pay all scheduled benefits. The CBO estimates that incoming payroll taxes will cover about 80 percent of scheduled benefits after depletion. The remaining 20 percent would have to come from somewhere else: Congress would have to raise payroll taxes, cut benefits, raise the retirement age, change the benefit formula, or use some combination of those options.

This shortfall is not unique to one year; it persists for decades. The CBO projects that even after 2032, the gap between payroll tax revenue and scheduled benefits will continue to widen as the population ages and the ratio of workers to beneficiaries declines.

Why the CBO's Date Differs From the Trustees' Estimate

The Social Security trustees (a group that includes the Secretaries of Treasury, Labor, and Health and Human Services, plus two public trustees) publish their own depletion projections every year. Their estimate often differs from the CBO's by a year or two. The difference comes from different assumptions about the future, not from different math.

The trustees and the CBO disagree most often on life expectancy trends. If one group assumes people will live longer on average, benefits will be paid for more years, and the trust fund depletes sooner. They also sometimes differ on wage growth assumptions and on how many people will claim benefits at each age. These are not facts; they are educated guesses about the future, and reasonable people can disagree.

When you see two different depletion dates in the news, check which organization produced each one. Both are legitimate; they just start from different assumptions about what the next 75 years will look like.

The CBO's Role in Policy Decisions

Congress uses CBO projections to understand the scale of the problem, but the CBO itself does not propose solutions. The agency publishes analysis of what would happen if Congress raised the payroll tax by 1 percentage point, or raised the retirement age by two years, or changed the benefit formula in a specific way. This lets lawmakers see the trade-offs of different choices without the CBO taking a position on which choice is best.

The CBO's projections are one input into the political debate. Lawmakers, advocacy groups, economists, and the public all interpret the same numbers differently and propose different fixes. The CBO's job is to make sure everyone is working from accurate information about what the current law produces and what changes would cost or save.

What the Shortfall Means for Current and Future Beneficiaries

If Congress does not change Social Security law before 2032, people claiming benefits after that date would receive smaller checks than the law currently promises. Someone claiming at 67 in 2033 would receive roughly 80 percent of their scheduled benefit; the other 20 percent would not be paid. This reduction would explore to all beneficiaries—retirees, disabled workers, and survivors of deceased workers.

The exact reduction would depend on how long the trust fund has been depleted and how much payroll tax revenue is available at that moment. The CBO does not predict a sudden cliff where benefits drop 20 percent overnight; instead, the reduction would be whatever is necessary to make incoming payroll taxes equal outgoing benefits each month.

People already receiving benefits when the fund depletes would also see reductions, unless Congress acts. There is no protection for current beneficiaries; the law treats all beneficiaries the same way once the trust fund is empty.

Frequently Asked Questions

Does the CBO's projection mean Social Security will definitely run out of money in 2032?

No. The CBO's projection assumes current law does not change. Congress can and likely will change Social Security law before 2032—by raising payroll taxes, adjusting benefits, changing the retirement age, or some combination. The projection shows what happens if nothing changes, not what will happen.

Why does the CBO give a range of years instead of one exact date?

The CBO publishes different reports in different years, and economic conditions change. A report published in 2023 might project depletion in 2033, while a report published in 2024 might project 2032, depending on new data about wages, employment, and life expectancy. The CBO also sometimes gives a range in a single report to show the uncertainty built into long-term projections.

If the trust fund depletes, will I still get Social Security?

Yes, but the amount would be reduced. Payroll taxes would still flow in, and the program would pay benefits from that money. The CBO estimates this would cover about 80 percent of scheduled benefits. Congress would have to decide whether to accept that reduction or change the law to maintain full benefits.

Can the CBO's projection change from year to year?

Yes. The CBO updates its projections annually based on new economic data, employment figures, and mortality trends. A strong economy might push the depletion date back by a year; higher life expectancy might pull it forward. The projection is a moving target, not a fixed prediction.

What options does Congress have to fix the shortfall?

Congress could raise the payroll tax rate (currently 12.4 percent split between employer and employee), raise or eliminate the income cap on payroll taxes, increase the full retirement age, reduce benefits for higher earners, or use some combination of these. The CBO publishes analysis of what each option would cost or save, but does not recommend which one Congress should choose.
