Social Security's Old-Age and Survivors Insurance trust fund is on track to run dry in the fourth quarter of 2032, according to the program's latest trustees' report. At that point, incoming payroll tax revenue would cover only 78 percent of scheduled benefits—forcing an automatic 22 percent cut for every retiree and survivor collecting checks unless Congress acts first.
The funding math has pushed a bipartisan pair of senators toward the most direct fix available: taxing more of what high earners make. Democratic Sen. Elizabeth Warren of Massachusetts and Republican Sen. Bernie Moreno of Ohio wrote a joint op-ed in The New York Times calling the removal of the payroll tax cap a "no-brainer." Their proposal would require workers to pay Social Security taxes on all earnings, not just the first $184,500—the 2026 threshold above which wages are currently exempt.
Under current law, both workers and employers each pay a 6.2 percent Social Security payroll tax, but only on wages up to that $184,500 ceiling. A nurse earning $90,000 pays the tax on every dollar she earns. A corporate lawyer billing $900,000 pays it on only the first $184,500—roughly 20 percent of total compensation. Warren and Moreno made that arithmetic explicit in their op-ed: "Why should a middle-class nurse pay a larger share of her paycheck than a wealthy corporate lawyer?"
The senators added: "The wealthiest Americans, who have benefited the most from America's opportunities, should contribute the same percentage of their income as a factory worker in Chillicothe, Ohio, or a teacher in Worcester, Mass."
Eliminating the cap entirely—without granting additional retirement benefits on the newly taxed wages—would close approximately 67 percent of Social Security's 75-year funding gap, according to Social Security Administration estimates. Warren and Moreno put the revenue figure at roughly $3 trillion over 10 years. Their bipartisan proposal is still being developed; the op-ed was the opening move, not a filed bill.
The policy's reach is narrower than the political debate suggests. Only about 6 percent of U.S. workers earn above $184,500 annually, meaning the tax increase would fall on a small slice of the labor force. Alex Beene, a financial literacy instructor at the University of Tennessee at Martin, said proposals targeting earnings above $250,000—a higher threshold than full cap elimination—would raise roughly more than $1 trillion over the next decade. But Beene was direct about the limit of that approach: even $1 trillion-plus in new revenue would not fully solve the program's long-term shortfall.
That gap between the proposal's ambition and the arithmetic is the central analytical problem. The Social Security Administration's own estimate—that full cap elimination closes 67 percent of the 75-year funding shortfall—means roughly one-third of the structural deficit remains even under the most aggressive version of the Warren-Moreno framework. A 10-year revenue figure of $3 trillion sounds large, but Social Security pays out roughly $1.4 trillion in annual benefits and climbing; the program's 75-year unfunded obligation runs into the tens of trillions by actuarial measure.
Other proposals are competing for space. Sen. Bernie Sanders, an independent from Vermont, reintroduced the Social Security Expansion Act, which also targets higher earners for increased contributions. At the Senate Budget Committee, Sen. Sheldon Whitehouse of Rhode Island put forward a separate plan that would apply additional Social Security taxes to individuals earning above $400,000—a higher floor than the Warren-Moreno approach, which targets everyone above $184,500.
The Whitehouse threshold matters structurally. A $400,000 floor would exempt a larger share of upper-middle-income earners from new taxes, concentrating the increase on genuinely high earners but also collecting less revenue than full cap removal. The tradeoff between political palatability and actuarial adequacy runs through every version of this debate.
The counterargument to cap elimination centers on benefits. Under current Social Security rules, higher lifetime earnings generate higher future benefits—the system is designed as a contributory program, not a pure wealth transfer. If Congress removes the cap on taxed wages but does not extend corresponding benefits to those additional earnings, it converts the upper tier of Social Security from an insurance program into a net transfer mechanism. Supporters of the change argue that is exactly the point; opponents argue it erodes the program's political architecture as a universal earned benefit rather than a means-tested welfare program.
The 2032 deadline is six years away—close enough that the legislative window is real but wide enough that Congress has historically deferred. The 1983 Social Security reforms, which last addressed a similar insolvency crisis, passed only after the program was weeks from missing benefit payments. That pattern of last-minute action is the base case here, which means the Warren-Moreno proposal is more likely a negotiating position than a standalone solution. The final package, if one materializes, will almost certainly combine some version of the payroll tax change with benefit adjustments and potentially a higher full retirement age—none of which are in the current bipartisan draft.
