Moreno and Warren Back Bill Lifting Payroll Tax Cap for Social Security

Summary

An unlikely pairing of Republican Sen. Bernie Moreno and Democratic Sen. Elizabeth Warren has produced a joint proposal to shore up Social Security by eliminating the cap on payroll taxes. Right now, workers only pay the 6.2 percent Social Security payroll tax on income up to $176,100; everything above that is exempt. Removing the ceiling would mean high earners pay the tax on every dollar they make, generating a significant new revenue stream. The political novelty of a Moreno-Warren collaboration is real, but the policy debate is sharper than the handshake photo suggests. Critics on the right and in libertarian circles argue the math doesn't hold up over the long run: a flood of new payroll tax revenue would eventually trigger higher benefit payouts for those same high-income earners, since Social Security benefits are tied to lifetime earnings. That dynamic, they say, makes the apparent windfall smaller than it looks, and possibly self-defeating over a 75-year actuarial window. Social Security's trust fund is projected to face shortfalls within roughly a decade, which has focused congressional attention on fixes ranging from benefit cuts to tax increases. The Moreno-Warren approach is one of the most aggressive revenue-side options on the table, and the fact that it has a Republican co-sponsor makes it politically notable even if its fiscal durability remains in dispute.
