In a Congress that can barely agree on lunch, Sen. Bernie Moreno (R‑Ohio) and Sen. Elizabeth Warren (D‑Mass.) are teaming up on one of the toughest problems in Washington: how to keep Social Security from running short of cash.
The unlikely duo is backing a plan to lift the cap on wages subject to Social Security payroll taxes, a move they say would pull roughly $3 trillion into the system over the next decade and help avert looming benefit cuts. In a jointly written opinion piece, they argue that scrapping the current limit on taxable earnings would give the program a fast cash infusion and extend the life of its main trust fund. It is one of the most visible cross-party efforts yet to answer the trustees' warnings about future shortfalls.
Moreno and Warren laid out the pitch in an opinion piece this week, detailed by Cleveland.com. Both senators sit on the Senate Banking, Housing, and Urban Affairs Committee, the panel that would likely hold hearings or draft legislative text if their idea moves forward. The Senate Banking Committee roster lists Moreno and Warren alongside members from both parties.
Trust Fund Timeline
The clock is not exactly on Congress's side. The Social Security trustees project that the primary retirement trust fund, known as the Old-Age and Survivors Insurance (OASI) fund, can pay full scheduled benefits only through the fourth quarter of 2032. After that point, incoming payroll tax revenue would cover about 78 percent of promised benefits, which translates into roughly a one in five cut unless lawmakers intervene.
That timeline and the projected shortfall come from the trustees' summary in the 2026 reports. The Social Security Administration lays out the trustees' intermediate estimates and explains how trust fund depletion would play out for beneficiaries if Congress does nothing.
How The Cap Works
The fight over the "cap" is about where Social Security taxes stop. Under current law, the taxable maximum is set each year. In 2026, it is $184,500 in wages. Employers and employees each pay 6.2 percent on earnings up to that level. Self employed workers effectively pay the full 12.4 percent, which means the maximum Social Security tax on covered earnings for a self-employed person in 2026 is about $22,878.
These figures and the mechanics of the wage base are standard fare in payroll guides and retirement coverage. LegalClarity lays out the 2026 wage base, tax rates, and how the math works for workers and businesses.
What Analysts Say
Policy analysts point out that over the decades, less of the nation's total earnings has actually been subject to the Social Security payroll tax. That shrinking tax base is one reason lifting or reshaping the cap keeps surfacing as a potential fix.
According to the Congressional Research Service, the share of aggregate covered earnings that is taxed fell from about 90 percent in 1982 to roughly 81 percent in 2021. Only a small slice of workers earn above the cap at all, about 6 percent overall. The CRS notes that around 9 percent of men and 4 percent of women exceed the taxable maximum. The Congressional Research Service analysis also walks through how changes to the contribution base could ripple through benefit formulas and long-term solvency projections.
Political Road Ahead
Even with a bipartisan headline, lifting the cap has an uphill political climb. Lawmakers are divided over whether higher earners who pay more should also get bigger benefits, and over how far they are willing to go in raising payroll costs for businesses and high-income workers. Past attempts to raise or eliminate the taxable maximum have repeatedly stalled, a familiar pattern highlighted in coverage of the new proposal. Cleveland.com outlines both the political push and the sticking points that tend to bog down reform efforts.
The next big question is whether Moreno and Warren turn their op-ed into actual bill language, seek committee hearings, or try to tuck a cap change into broader budget talks in the months ahead. If Congress does take up the idea, analysts say the details will matter most: who pays, whether benefits are recalculated for high earners, and how quickly any shift is phased in. Those choices will determine how much of Social Security's long-term gap gets closed, and who feels the pinch.
