Taxing high earners to help fund Social Security gains bipartisan attention — what it could mean for benefits

Renewed bipartisan interest is emerging around raising Social Security payroll taxes on high-income workers as a potential solution to the program’s funding challenges. Traditionally championed by Democratic lawmakers, this approach has recently gained support from several Republicans, including Senator Bernie Moreno of Ohio and Representatives Tom Cole of Oklahoma and Lloyd Smucker of Pennsylvania. In June, Moreno and Democratic Senator Elizabeth Warren jointly advocated for lifting the Social Security payroll tax cap in a New York Times opinion piece, calling it a practical remedy.

Social Security currently faces substantial financial pressures. According to the program’s trustees, the system may be unable to pay full scheduled benefits beginning in the fourth quarter of 2032, at which point only 78% of retirement benefits could be covered. The program faces an estimated nearly $30 trillion shortfall over a 75-year period. Currently, workers pay Social Security payroll taxes only on earnings up to $184,500, meaning high earners contribute for only part of the year.

Research indicates that modifying the payroll tax structure could meaningfully address the shortfall’s magnitude. Completely eliminating the taxable maximum would cover 67% of the 75-year solvency gap without benefit increases, or 48% if benefits were expanded. Alternatively, setting the taxable maximum at 90% of earnings would address 28% of the gap without benefit increases. Public opinion surveys conducted in 2024 showed strong support for eliminating the payroll tax cap on earnings above $400,000, with nearly equal backing for raising the payroll tax rate from 6.2% to 7.2%.

However, economists and policy analysts caution about potential drawbacks. Lifting the payroll tax cap would represent the largest tax increase since 1982 and could have significant economic consequences. Research suggests that expanding the cap to cover 90% of wages could eliminate approximately 900,000 jobs and reduce GDP by 0.7%. Critics note that high-income earners might respond by reducing work efforts or restructuring compensation, and that the proposal targets individuals already facing high marginal tax rates.
