The Social Security trust fund could have paid full benefits until 2059 if the share of the economy subject to payroll taxes had held steady since the early 1980s, according to new research released this week by AARP. Instead, the Social Security trust fund faces an automatic benefit cut in the early 2030s unless Congress acts, a gap the AARP Public Policy Institute says was pulled forward by about 25 years as more income shifted out of reach of the payroll tax.
The findings arrive as lawmakers return to Washington for a lame-duck session and as a new Congress prepares to take office in January. Here is what the report found about the Social Security trust fund, what the government's own trustees project, how each party approaches the issue, and what it could mean for your retirement income.
What the AARP Social Security Trust Fund Report Found
The study, written by Richard Johnson, vice president of financial security at the AARP Public Policy Institute, measures how much of the nation's income is actually taxed to fund Social Security. Using data from the Social Security Administration and the Bureau of Economic Analysis, it found that taxable earnings equaled about 41% of gross domestic product in 1983, the year Congress last passed a major solvency package.
By 2025, that share had fallen to about 34% of GDP, and AARP expects it to stay near that level for decades. The organization's model estimates that if the 41% share had held, the program would have collected roughly $10.8 trillion more in revenue, enough to keep the Social Security trust fund paying full scheduled benefits until 2059.
Why less income is being taxed
Payroll taxes apply only to wages up to an annual limit, known as the taxable maximum, which is $184,500 in 2026, according to the Bipartisan Policy Center. Workers and employers each pay 6.2% on earnings below that cap. AARP's analysis attributes the Social Security trust fund revenue squeeze to broad economic changes: a growing share of wage income going to top earners above the cap, and more national income arriving as capital or business income that is not subject to the payroll tax at all.
The Bipartisan Policy Center reports that the payroll tax now covers about 83% of all covered earnings, compared with 90% in 1983. In its press release, AARP said one of its central conclusions is simple: "Strengthening Social Security does not require recreating the economy of 1983."
What AARP is asking Congress to consider
Johnson said policymakers could look at raising or eliminating the taxable earnings cap and at applying targeted contributions to certain forms of capital or business income. AARP also cited its own polling, which found that 80% of all voters and 90% of older voters say it is very or extremely important for Congress to protect Social Security from cuts. The group said newly elected members of Congress should keep that in mind.
AARP stressed that the 2059 date is a hypothetical scenario. It does not change current law or replace the official projections, which point to a much earlier shortfall.
Social Security Trust Fund Outlook From the Trustees
The official benchmark comes from the program's Board of Trustees, whose 2026 Trustees Report highlights were released on June 9. The trustees include Treasury Secretary Scott Bessent, Social Security Commissioner Frank Bisignano, Health and Human Services Secretary Robert F. Kennedy Jr. and Acting Labor Secretary Keith Sonderling.
- The retirement and survivors (OASI) Social Security trust fund is projected to run dry in the fourth quarter of 2032. At that point, incoming revenue would cover about 78% of scheduled benefits.
- If the retirement and disability funds were combined, which would require an act of Congress, reserves would last until 2034 with about 83% of benefits payable.
- The disability insurance fund is projected to remain solvent for the full 75-year period.
- The 75-year actuarial deficit grew to 4.42% of taxable payroll, up from 3.82% a year earlier.
Combined Social Security trust fund reserves fell by $160 billion in 2025 to $2.56 trillion. The program took in about $1.45 trillion that year while spending about $1.61 trillion, and it paid benefits to roughly 70 million people by year's end.
What changed in this year's projection
The trustees said the largest driver of the worse long-range outlook was a lower assumption for future birth rates, cut from 1.90 to 1.75 children per woman. Lower immigration assumptions also played a role, as did the 2025 tax law known as the One Big Beautiful Bill Act, which reduces revenue the Social Security trust fund receives from taxing benefits. The Bipartisan Policy Center notes there are now about 2.9 workers per beneficiary, a ratio projected to fall to 2.2 by the 2070s.
According to the trustees, closing the 75-year gap immediately would require raising the combined payroll tax rate from 12.4% to 16.65%, cutting all benefits by about 25.2%, or some mix of the two. Commissioner Bisignano said in June that lawmakers and the agency should work together to keep the trust funds on stable footing.
How Democrats and Republicans Approach the Social Security Trust Fund
Proposals to shore up the Social Security trust fund have long divided the parties, although some ideas have drawn interest from both sides.
Democratic proposals
Rep. John Larson (D-Conn.), the top Democrat on the House Social Security Subcommittee, and Sen. Richard Blumenthal (D-Conn.) have sponsored the Social Security 2100 Act. As described by Newsweek, the bill would apply the payroll tax to wages above the current cap and extend it to certain investment income for people earning more than $400,000, while also raising the minimum benefit. Larson has argued that the 2026 trustees' findings show the need to act and has criticized administration tax policy.
Republican positions
Republicans have generally opposed broad payroll tax increases. When the 2100 Act received a hearing in 2021, GOP members of the subcommittee said it was too costly and argued for more targeted changes. This year, the National Republican Senatorial Committee ran ads saying Democrats want to tax seniors' benefits, and Republicans point to the 2025 law's new deduction for older Americans, worth up to $6,000 per person through 2028, as tax relief for retirees. Democrats counter that the law does not eliminate the taxation of benefits.
A rare point of overlap
In June, Sen. Elizabeth Warren (D-Mass.) and Sen. Bernie Moreno (R-Ohio) jointly called for lifting the payroll tax cap so higher earners contribute more, according to a statement from Larson's office. No single solvency plan has yet gathered enough support in both chambers to pass.
What It Means for You: Social Security Trust Fund and Your Benefits
Nothing in the AARP report changes anyone's benefit today. Checks continue on their normal schedule, and the Social Security trust fund is still projected to pay full benefits for several more years. The following points are our own analysis based on the official figures.
If you already receive benefits
Under current law, an across-the-board reduction of roughly 22% would hit retirement and survivor benefits once the OASI Social Security trust fund is exhausted in late 2032, unless Congress acts first. For a retiree receiving the average monthly benefit of about $2,017 cited by the Bipartisan Policy Center, a 22% cut would mean roughly $440 less per month. Building a budget that can absorb some uncertainty, and reviewing other income such as pensions or savings withdrawals, may help.
If you are still working
- Check your earnings record and benefit estimate in your my Social Security account at ssa.gov to make sure your wages are recorded correctly.
- High earners should watch the cap debate closely, since raising or removing it would increase payroll taxes on wages above $184,500.
- Review your paycheck withholding as tax rules change; our 2026 tax withholding checklist walks through the basics.
- Keep saving in a 401(k), IRA or other account so Social Security is one source of retirement income, not the only one.
Watch the broader economy
Inflation and interest rates also shape retirement finances, from annual cost-of-living adjustments to the yields on savings. For background on recent rate expectations, see our coverage of the possible Fed rate hike. Any Social Security trust fund deal in Congress is likely to involve some combination of new revenue and benefit changes, so following the debate can help you plan.
The Bottom Line
AARP's study adds a new data point to a long-running debate: the Social Security trust fund problem reflects not only an aging population but also a shrinking share of national income subject to the payroll tax. The trustees' official projections still show the Social Security trust fund for retirement benefits running out in 2032. How and when Congress responds will determine whether that date brings a benefit cut, higher taxes, or a different solution.
