What is the Social Security Expansion Act?

A bill (S.770) from Sen. Bernie Sanders and Sen. Elizabeth Warren, with House companion legislation, that would raise every Social Security benefit by $200 a month ($2,400 a year), expand cost-of-living adjustments, and fund the changes by applying the payroll tax to income above $250,000 plus a broader net investment income tax.

Is the $200-a-month Social Security increase happening?

No. The Social Security Expansion Act is an introduced bill, not law. It has no Republican support and no scheduled vote, so no benefit increase from it is imminent.

Who would pay more under the Sanders plan?

People with income above $250,000 a year. Wages between the current taxable cap ($184,500 in 2026) and $250,000 would stay untaxed — a 'donut hole' — while income above $250,000 would owe payroll tax, and high earners would also pay a larger net investment income tax. Sanders' office says 91% of Americans would see no tax increase.

Would the bill really keep Social Security solvent for 75 years?

That is the sponsors' claim, based on the design of taxing income above $250,000. An independent actuarial score of the current version has not been publicly released, so treat the 75-year figure as the sponsors' estimate rather than a verified projection.

How is this different from the PROMISE Act?

They are opposites in kind. The Sanders bill picks a specific policy: expand benefits, tax high incomes. The PROMISE Act picks no policy — it creates a fast-track process forcing Congress to vote on some future solvency plan. Sanders opposes the PROMISE Act, warning the process could produce benefit cuts; its supporters say a forced vote is the only way anything passes.

Sanders' $2,400 Social Security Boost, Explained

The Social Security Expansion Act would add $200 a month to every benefit check, funded by taxing income above $250,000 — and Sanders is pitching it as the alternative to the fast-track PROMISE Act. It's a bill with long odds, not a coming raise. Here's what it would do and who would pay.

Sen. Bernie Sanders is promoting a plan that would raise every Social Security check by $200 a month — $2,400 a year — funded by applying the payroll tax to income above $250,000. The Social Security Expansion Act (S.770), sponsored by Sanders (I-VT) and Sen. Elizabeth Warren (D-MA) with companion legislation in the House, is back in the headlines because Sanders is pitching it as the alternative to the fast-track PROMISE Act now dividing Congress. It is a bill, not law — and in the current Congress its odds are long. Here's what it would actually do, who would pay, and where it fits.

What the bill would do

A flat $200-a-month increase for every Social Security beneficiary — retirees, disabled workers, survivors — worth $2,400 a year.
Expanded cost-of-living adjustments, aimed at better tracking the costs seniors actually face.
Sponsors say the package would keep the program solvent for 75 years.

Who would pay for it

Today, workers pay Social Security tax only on their first $184,500 of wages (2026). The bill would leave that cap in place but apply the payroll tax again to all income above $250,000 — creating a "donut hole" between $184,500 and $250,000 that stays untaxed (a design similar to the Moreno–Warren cap proposal). It would also raise and broaden the net investment income tax for high earners, so the funding doesn't rest on wages alone.

Sanders' office says the plan would achieve this "without raising taxes on 91 percent of Americans" — consistent with independent survey data showing that taxing higher earners is the most broadly popular fix across both parties. Worth noting: an independent actuarial score of the current version hasn't been publicly released, so the 75-year solvency claim comes from the bill's sponsors.

The other end of the spectrum

It's clarifying to see how wide the debate now runs. At one pole, this bill would expand benefits for everyone and fund them from high incomes. At the other, a think-tank proposal would cap the very largest Social Security checks at $100,000 a year per couple. In between sit the process bills — like the PROMISE Act — that don't pick a policy at all, but force Congress to vote on something before the trust fund runs short around 2032. Sanders opposes that approach, warning it could fast-track cuts; AARP opposes it too, on different grounds. Our process-bills explainer covers that fight.

Realistically, what are its chances?

Slim in the near term. The bill has attracted Democratic cosponsors but no Republican support, and its tax increases make it a nonstarter for the current majority. Its practical role right now is as a negotiating pole: it defines the expansion end of the debate, the same way benefit-cap and retirement-age proposals define the other end. Whatever package eventually emerges to address the projected 2032 shortfall will be measured against both poles.

What it means for you

Nothing changes today — no $200 increase has passed, and no vote is scheduled. If you see headlines suggesting a raise is imminent, that's ahead of reality. What the bill usefully signals is the shape of the coming debate: every serious fix now on the table involves some mix of higher revenue from high earners, benefit changes, or both, and where lawmakers land will determine what happens to your benefit after 2032.
