A proposal backed by Sen. Bernie Sanders could raise Social Security benefits by roughly $200 a month for many beneficiaries, but no such increase has been approved and the Social Security Administration has not scheduled a new $200 payment.
The proposal is the Social Security Expansion Act, introduced as S. 770 in February 2025. Sanders renewed his push for the legislation on Aug. 4, 2026, after this year’s Social Security Trustees report intensified concern about the retirement program’s long-term finances.
The legislation’s headline benefit is what recent coverage has nicknamed the “Bernie Bump.” Sanders’ 2025 Social Security Expansion Act fact sheet describes an across-the-board increase of $2,400 a year, or $200 a month, for current and new Social Security beneficiaries. But the actual text of S. 770 does not simply tell SSA to deposit a separate flat $200 into every recipient’s account. It changes the formula used to calculate a worker’s primary insurance amount, or PIA.
That distinction matters when asking who could qualify. Section 2 applies to monthly insurance benefits under Title II of the Social Security Act, the system covering retirement, Social Security Disability Insurance and benefits derived from an insured worker’s record. The bill also orders SSA to recompute PIAs for people who became eligible before 2026.
That makes current retirees and disabled workers central beneficiaries of the proposal, while spouses, children and survivors whose payments are based on a worker’s PIA could also be affected. Their increase, however, would not necessarily equal exactly $200 because family and survivor benefits can represent only a percentage of the worker’s underlying PIA.
SSI-only recipients should be especially careful with headlines about the proposal. Supplemental Security Income is a separate Title XVI program. Section 2’s headline benefit increase expressly applies to Title II monthly insurance benefits, so an SSI recipient should not assume that the legislation promises a standalone $200 increase to an SSI check.
There is another reason $200 should be understood as a shorthand rather than a universal payment amount. Under current law, SSA’s 2026 PIA formula applies a 90% factor to the first $1,286 of a newly eligible worker’s average indexed monthly earnings. S. 770 would raise that factor to 95% and increase the first bend point by 18% for workers becoming eligible after 2025.
For a 2026 worker with earnings above that first adjusted bend point, an Investozora calculation using those official inputs produces an increase of about $210 in the PIA before claiming-age or other adjustments. Lower-earning workers and auxiliary beneficiaries can produce different results. That is why understanding Social Security bend points is more useful than treating $200 as a guaranteed flat check.
The proposal would also change future cost-of-living adjustments by replacing the CPI-W used today with a Consumer Price Index for the Elderly, or CPI-E. That is separate from the initial benefit increase. The bill would therefore combine a higher starting benefit formula with a different inflation measure for future adjustments rather than replacing the normal COLA system with the “Bernie Bump.”
The key dates for beneficiaries watching the proposal are:
- February 27, 2025: Sanders introduced S. 770; it was read twice and referred to the Senate Finance Committee. A House companion, H.R. 1700, was introduced the same day.
- January 1, 2026: The introduced Senate text says its across-the-board benefit formula change would take effect from this date. Because that date has already passed and the bill is still pending, it is not a current SSA payment date.
- June 9, 2026: Social Security’s Trustees projected the OASI retirement and survivor trust fund would exhaust its reserves in the fourth quarter of 2032, when continuing revenue would cover about 78% of scheduled benefits if Congress made no changes.
- August 4, 2026: Sanders again called for lawmakers to support his expansion plan, including the $2,400 annual benefit increase.
- August 31, 2026: S. 770 remains at the introduced and committee-referral stage. There is no enacted $200 increase and no SSA payment schedule for one.
Financing is the other half of the proposal. Social Security taxes currently apply to earnings up to $184,500 in 2026, according to SSA’s official 2026 taxable-earnings limit. S. 770 would preserve a gap between that taxable maximum and $250,000, then apply Social Security payroll taxes again to earnings above $250,000.
It would also change taxation of certain investment and business income. Sanders argues those additional revenues could finance higher benefits while strengthening Social Security; his fact sheet says the package would extend solvency for 75 years. Readers can compare that approach with other options in Investozora’s Social Security reform proposals explained.
The renewed debate comes as the financial pressure on Social Security has become more immediate. The 2026 Trustees report says the OASI fund could pay full scheduled retirement and survivor benefits only through the fourth quarter of 2032 under current-law projections, after which 78% would initially be payable from continuing income.
Investozora has examined that risk separately in its report on Social Security’s projected 78% benefit level in 2032. The Sanders proposal represents one possible response to that problem; it is not the policy currently governing anyone’s check.
For beneficiaries, the practical answer is therefore simple: there is nothing to apply for and no $200 payment to claim today. The amount becomes real only if legislation passes Congress and becomes law.
Until then, Social Security payments continue under existing benefit and COLA rules, and any message claiming beneficiaries can sign up now for a “Bernie Bump” should not be treated as an official SSA announcement.
