WASHINGTON — A growing share of U.S. wages is falling outside the portion of earnings subject to Social Security payroll taxes as income growth among higher-paid workers continues to outpace gains for most employees, according to recent analyses of federal data and the latest Social Security projections.
The issue has drawn renewed attention following the release of the 2026 Social Security Trustees Report and related research examining the program’s long-term finances. Analysts said the taxable share of national wages has declined over several decades because earnings above the annual Social Security tax cap are exempt from the program’s payroll tax. In 2026, the taxable maximum is $184,500, according to the Social Security Administration.
The Bipartisan Policy Center said in a June analysis that payroll taxes now apply to about 83% of covered wages, down from roughly 90% in 1983. The group attributed the change largely to faster wage growth among higher-income earners whose compensation increasingly exceeds the taxable maximum.
“Higher-income Americans’ wages have grown faster than the taxable maximum,” a recent analysis cited by CBS News said, noting that earnings above the cap are not subject to Social Security payroll taxes.
Social Security is financed primarily through payroll taxes paid by workers and employers. The tax rate remains 6.2% for employees and an equal amount for employers, while self-employed individuals pay the combined rate. The Social Security Administration said the contribution and benefit base increased to $184,500 in 2026 from $176,100 in 2025.
Supporters of raising or eliminating the wage cap argue that doing so could increase revenue flowing into the program. Several policy proposals under discussion in Congress would subject a larger share of high-income earnings to Social Security taxes, according to policy analysts.
Others have cautioned that any changes to the tax structure would need to be weighed alongside questions about future benefits, economic effects and broader retirement policy. Details of potential legislative action remain unclear.
The debate comes as Social Security faces long-term funding challenges. The 2026 Trustees Report projected that the program’s primary trust fund could be depleted in 2032 absent congressional action, after which incoming revenue would cover only a portion of scheduled benefits. Demographic changes, including population aging and lower worker-to-beneficiary ratios, remain significant factors in the program’s financial outlook, according to the report and independent analyses.
For now, the Social Security Administration continues to collect payroll taxes under existing law, with the taxable wage cap adjusted annually based on changes in national average wages. Officials have not announced any changes to the current tax structure.
