Sanders Plan Would Tax Earnings Above $250,000 to Shore Up Social Security
Sen. Bernie Sanders has proposed applying Social Security payroll taxes to earnings above $250,000. The plan, as MarketWatch reported on November 9, 2026, would eliminate the taxable maximum, the ceiling above which wages escape the program's payroll tax. The stated aim is to keep Social Security solvent for generations, meaning able to keep paying scheduled benefits.
The taxable maximum is the mechanism at issue. Wages are taxed only up to a set annual limit. Under the 2022 limit of $147,000, the most a wage and salary worker directly contributed to Social Security was $9,114, according to Congressional Research Service data. Earnings above that ceiling carry no additional payroll tax, so a high earner's marginal payroll tax rate, the rate on the next dollar earned, falls to zero once the cap is reached. Removing the cap, or in the Senate proposal's framing, extending the tax past $250,000, changes the marginal cost of additional wage income for the highest earners.
The legislative vehicle is S.770 in the 119th Congress, titled the Social Security Expansion Act and sponsored by Sen. Sanders. As described in the bill text, it would extend payroll taxes to wages, salaries, and self-employment earnings above $250,000. Benzinga reported that the broader Sanders proposal would also increase Social Security benefits by at least $2,400 annually. The benefit increase and the revenue change are presented together, so the cost side and the solvency side have to be read against each other, not in isolation.
In my view, the threshold is the design question that matters most to anyone who models this for a living. A $250,000 floor concentrates the change on a narrow band of high earners, while eliminating the maximum outright would reach every dollar of wage income above the current ceiling. Those are different revenue bases with different behavioral responses, including how earners time bonuses, exercise equity compensation, and shift income between wages and self-employment. Anyone building projections will need the exact definition of covered earnings in the bill text.
The benefit side points the other way. Congressional Research Service data indicates that 48% of Social Security beneficiaries will pay income tax on their benefits in 2026. Separately, H.R.904, titled No Tax on Social Security, was introduced in the House on January 31, 2025. The bill would exclude Social Security and Tier I railroad retirement benefits from gross income, meaning the total income on which income tax is calculated. The Senate proposal raises revenue from high earners, while the House bill would reduce taxation on benefits. The two sit at opposite ends of the same question about how the program is financed and taxed.
For ordinary savers and workers, the practical point is simple. Under this proposal, a worker earning above $250,000 would face a larger payroll deduction, and beneficiaries would see a benefit increase of at least $2,400 a year. Neither outcome is law. Proposals of this kind become consequential only once the financing, the effective date, and the solvency projections are fixed in enacted text, and those details are the ones to watch.
