Roughly 70 million Americans who receive Social Security benefits would see their monthly checks rise by $200 under legislation filed by Sen. Bernie Sanders, an independent from Vermont. The Social Security Expansion Act, introduced as S. 770 in the Senate and H.R. 1700 in the House during the 119th Congress, rewrites the benefit formula itself rather than relying on the annual cost-of-living adjustment. But the bills sit at the introduction stage, and neither chamber has scheduled a vote, leaving the proposed increase entirely dependent on congressional action that has not yet materialized.
Why a permanent $200 monthly increase carries fiscal weight
The $200-per-month framing is not a one-time stimulus payment. It is a structural change to how benefits are calculated, which means the added cost compounds every year as the beneficiary population grows and as future COLAs build on a higher base amount. That distinction matters because Social Security already faces a long-term funding gap. The Congressional Research Service summary of the 2025 Trustees Report documents the program’s actuarial deficit and projects that the Old-Age and Survivors Insurance trust fund will not be able to pay full scheduled benefits indefinitely under current law.
If the Social Security Expansion Act were enacted, a measurable share of that deficit would shift from the trust fund to general revenue or new tax receipts within five years. Future Trustees Reports would reflect the change, and comparing those projections against the current CRS baseline would show whether the bill’s financing provisions actually close the gap or simply redirect the shortfall. The Congressional Budget Office maintains policy analyses that outline the budget trade-offs any permanent benefit increase would create, though no formal score of the current bill text has been published.
The annual cost-of-living adjustment, by contrast, is automatic. The Social Security Administration’s 2025 COLA fact sheet explains how that percentage is calculated from consumer price data each year. Sanders’ bill would layer a flat $200 increase on top of whatever COLA beneficiaries already receive, a key difference that separates this proposal from the routine annual adjustment many retirees confuse it with. Because the extra $200 would be built into the base benefit, every future COLA would be calculated on a higher starting point, magnifying the long-run cost beyond the headline monthly figure.
Sponsors, bill text, and the actuarial record
Sanders filed the Senate bill with Sen. Elizabeth Warren as a co-sponsor. On the House side, Rep. Val Hoyle and Rep. Jan Schakowsky introduced the companion measure. In a press release, Hoyle’s office described the legislation as targeting “the millions of seniors who rely on Social Security as their primary source of income” and confirmed the $200-per-month benefit framing. The text also includes changes to how higher earners are taxed for Social Security and adjustments to minimum benefits, positioning the package as both an expansion and a solvency plan.
The Social Security Administration’s Office of the Chief Actuary maintains an online catalog of solvency proposals that includes analysis of earlier versions of the Social Security Expansion Act. Those prior actuarial memoranda modeled how raising or eliminating the earnings cap and adjusting benefit formulas would affect the trust funds over a 75-year horizon. However, no Chief Actuary letter specific to the 119th Congress version of S. 770 appears on that index as of mid-2026, which means the actuarial cost of the current bill text has not been independently scored by the agency responsible for modeling trust fund impacts.
Without that updated analysis, lawmakers and the public are left to extrapolate from older estimates that may not fully capture changes in demographics, wage growth, or the precise mix of tax and benefit provisions in the latest draft. That uncertainty complicates efforts to compare Sanders’ proposal with other reform ideas, such as more targeted benefit boosts or incremental payroll tax increases, which have been scored in detail by the actuaries and the CBO.
What it would mean for beneficiaries and the debate ahead
For current beneficiaries, a $200 monthly increase would be meaningful. For someone receiving a $1,600 retirement benefit, the change would represent a 12.5% raise before taxes, and it would arrive automatically each month rather than as a lump-sum payment. Low-income retirees, disabled workers, and surviving spouses who rely on Social Security for most of their income would see the largest relative improvement in their budgets, particularly in areas where housing and medical costs have outpaced recent COLAs.
At the same time, embedding a flat increase across the board raises questions about distribution. Higher-income retirees who already receive larger checks would still get the same $200 boost, even though they may be less financially vulnerable. The bill’s supporters argue that pairing the benefit expansion with new revenue from higher earners balances that concern. Critics counter that any broad-based increase should be carefully calibrated to avoid deepening the program’s long-term imbalance.
For now, the Social Security Expansion Act remains an opening bid rather than imminent law. With no committee markups or floor votes scheduled, the proposal functions as a marker in the broader debate over how aggressively to expand benefits versus how quickly to shore up solvency. Whether a $200 monthly increase ever reaches beneficiaries will depend not only on political appetite for higher taxes or reallocated revenues, but also on the detailed actuarial work that has yet to be completed for this specific version of the bill.
