Workers earning above $176,100 a year pay no Social Security tax on income beyond that threshold, and a former head of the agency told Congress that eliminating or sharply raising that ceiling is the single policy change large enough to keep benefits whole for decades. Martin O’Malley, testifying as Commissioner of Social Security during the 118th Congress, put it bluntly: “raise the cap $400,000 and up… just remove it.” His argument lands at a moment when the program’s trust funds are on track for depletion in the mid-2030s, after which incoming payroll taxes would cover only a fraction of scheduled payments to tens of millions of retirees.
Why O’Malley’s call to lift the cap carries urgency
The latest projections in the 2025 Trustees Report show that the combined Old-Age and Survivors Insurance and Disability Insurance trust funds face exhaustion within roughly a decade under current law. Once reserves run out, the program can pay only what it collects in real time, which the Trustees estimate would cover about 80 percent of scheduled benefits. For an average retired worker, that gap translates into a steep monthly cut with no phase-in period and no automatic fix on the books.
O’Malley’s testimony framed the financing hole as a revenue problem, not a spending problem. The statutory payroll cap, which rises each year with average wages, shields all earnings above the threshold from the 12.4 percent combined employer-employee tax. As top incomes have grown faster than median wages over recent decades, a shrinking share of total national earnings falls inside the taxable window. That structural drift widens the gap between what the program owes and what it collects.
That framing matters because it narrows the menu of realistic fixes. If the shortfall stems primarily from eroding taxable payroll rather than runaway benefit promises, then restoring the tax base becomes the central task. In O’Malley’s view, lifting or removing the cap does exactly that, by reconnecting high earners to the program’s financing in proportion to their growing share of national income.
What the hearing record and actuarial data show
During his appearance before the House Ways and Means Committee, O’Malley argued that no combination of benefit trims alone can close the shortfall without deep cuts to current or near-retirees. His preferred alternative, removing the cap entirely, would subject every dollar of wages and self-employment income to the payroll tax. A narrower version, raising the cap to $400,000, would still leave a band of high earners partially exempt but would capture a large share of currently untaxed earnings.
The Social Security Administration’s Office of the Chief Actuary maintains a menu of scored policy options that test various cap increases against the 75-year actuarial deficit. In that catalog of solvency provisions, options that apply the payroll tax to all earnings eliminate most of the projected shortfall, while smaller adjustments, such as a $250,000 threshold, close far less. No other single revenue or benefit change in the OCACT menu comes close to the same effect. The gap between full removal and partial increases is not marginal; it is the difference between a program that stays solvent for multiple decades and one that still faces a reckoning within a generation.
Those estimates also underscore that design details matter. Some proposals would tax all earnings but credit additional taxed wages toward higher future benefits, while others would limit extra benefit accruals to keep the focus on shoring up the trust funds. The more new revenue that flows back out as larger checks for top earners, the less net improvement to long-run solvency. O’Malley, in emphasizing the revenue side, implicitly points toward versions that raise more than they ultimately pay out.
Gaps in the evidence and what to watch next
O’Malley’s testimony did not come with a formal OCACT scoring sheet attached to his specific $400,000-or-remove proposal. The hearing record contains his policy preference and his characterization of its impact, but the precise year-by-year benefit-payable percentages under that exact design are not published in the transcript. Separately, the Trustees Report does not endorse any particular reform; it simply lays out the scale and timing of the shortfall under current law.
That leaves lawmakers and the public with a clear sense of direction but incomplete technical detail. The actuarial options show that lifting or eliminating the cap can, in principle, erase most of the deficit, yet they do not map perfectly onto the shorthand O’Malley used at the hearing. Any bill that follows his advice would still need to specify how quickly the cap rises, whether new taxes buy new benefit credits, and how to treat non-wage income that currently falls outside the payroll base.
In the coming debates, two questions will loom. First, will Congress treat the 2030s depletion date as a hard deadline that rules out gradual, back-loaded fixes? Second, will lawmakers accept the political risk of concentrating new taxes on high earners rather than spreading smaller changes across the entire workforce and beneficiary population? O’Malley has staked out one side of that argument, betting that a straightforward change to the cap is both technically sufficient and easier to explain than a tangle of smaller cuts and hikes.
For now, the actuarial tables and the hearing record point in the same broad direction: without more taxable payroll, promised benefits cannot be paid in full. Whether Congress chooses to follow O’Malley’s prescription, or to assemble a more complex package of incremental changes, will determine how sharply, and on whom, the eventual adjustments fall.
