Social Security’s retirement trust fund is projected to be depleted by 2032, with the combined retirement and disability trust funds expected to run out by 2034. If Congress does not act, retirement benefits would face an automatic 22% reduction beginning in 2032 because benefits could only be paid from incoming payroll tax revenue.

Trust fund depletion doesn’t mean Social Security stops paying benefits. However, it would trigger significant across-the-board cuts affecting millions of retirees and future beneficiaries.

Why Social Security’s Finances are Deteriorating

Several long-term trends continue to weaken the program’s finances:

• Lower birthrates have reduced the number of workers paying payroll taxes
• Growing income inequality means a larger share of earnings exceeds the payroll tax wage cap.
• Updated projections assume lower fertility rates, reduced immigration, and higher emigration.
• Changes in tax law under the One Big Beautiful Bill Act are expected to further reduce trust fund revenue.

As a result, Social Security’s actuarial deficit increased from 3.82% to 4.42% this year, meaning a larger revenue increase or benefit reduction will be needed to maintain solvency over the next 75 years.

What Happens if the Trust Fund Runs Out?

Social Security’s trust funds operate like checking accounts. Payroll taxes and interest flow in, and benefits flow out. Following major reforms in 1983, reserves grew substantially, but the system began drawing down those reserves in 2021 as baby boomer retirements accelerated.

Once reserves are exhausted:

• Social Security cannot borrow money to cover benefit costs
• Benefits would be limited to available tax revenue
• Retirement benefits would be reduced by roughly 22%

The impact would be significant:

• More than 59 million Americans receive retirement benefits
• Another 11 million receive disability benefits
• About 40% of beneficiaries rely on Social Security for at least half of their income

Current retirees would feel the immediate effects, while younger workers would face increased uncertainty in retirement planning.

How Congress Could Fix Social Security

According to Social Security Chief Actuary Karen Glenn, restoring solvency requires:

• Increasing revenue by roughly one-third
• Reducing benefits by about one-fourth
• Adopting a combination of both approaches

Some experts also believe Congress could temporarily use general federal revenues as an emergency bridge if lawmakers approach the deadline without a long-term solution.

Potential Revenue Options

Lift or Eliminate the Payroll Tax Cap. Workers currently stop paying Social Security taxes on earnings above $184,500 (2026). Eliminating or raising this cap has gained bipartisan interest.

Raise the Payroll Tax Rate. Increasing payroll taxes for workers and employees could generate substantial new revenue, likely through a gradual phase-in.

Tax Investment Income. Some proposals would apply a 6.2% tax on investment income earned by high-income households.

Potential Benefit Reduction Options

Change the Benefit Formula. Future initial benefits could be linked to inflation rather than wage growth. Because wages generally rise faster than inflation, this would gradually lower benefits over time.

Means-Test Benefits. Some proposals would reduce benefits for higher-income retirees or limit cost-of-living adjustments based on household income.

Raise the Retirement Age. Increasing the full retirement age from 67 to 69 has periodically been proposed. Each one-year increase roughly equals a 7% reduction in lifetime benefits for future retirees.

Why Broad Benefit Cuts May be Less Likely

As the deadline approaches, policymakers may increasingly favor revenue increases over major benefit reductions.

Cutting benefits for current retirees is politely difficult, while reducing benefits only for future retirees would not generate savings quickly enough to close the funding gap.

Additionally, Social Security has already become less generous over time. According to the Center for Retirement Research at Boston College, the average worker retiring at age 65 will receive Social Security benefits replacing about 30% of pre-retirement income in 2035, down from 42% in 1995.

Americans Face Growing Retirement Challenges

Many Americans already feel financially unprepared for retirement:

• 80% of Americans believe the U.S. faces a retirement crises (up from 67% in 2020).
• Only 61% of workers feel confident about retirement security, down from 67% a year earlier.
• Rising healthcare costs, inflation, and uncertainty about future benefits remain major concerns.

Retirement savings often fall short:

• Among households aged 55-64 with a 401(k), the lowest-income group had a median balance of just $25,000 in 2022.
• The middle-income group had a median balance of $220,000.

At the same time, retirement saving is slowing:

• The percentage of Americans increasing retirement contributions fell to 39%.
• The share reducing retirement savings rose from 8% to 14%.

Rising Senior Poverty

The U.S. Census Bureau reported that poverty among Americans aged 65 and older rose to 15.4% in 2025, up from 12.0% in 2019. It is now the highest poverty rate of any age group.

As retirement insecurity grows, the pressure on Congress to address Social Security’s financial shortfall continues to increase. The central question is no longer whether changes will be needed, but which combination of tax increases, benefit adjustments, or other measures lawmakers ultimately choose.
