The Social Security 2100 Act is drawing fresh attention because it promises a bigger benefit formula, a different inflation measure, and more tax revenue for the trust fund. The important planning point is simpler: none of those changes are current law.
Sen. Richard Blumenthal said on July 22, 2026, that he introduced the Senate version of the bill after Rep. John Larson introduced it in the House. The proposal would increase benefits for current and future beneficiaries, use an improved cost-of-living adjustment, strengthen the minimum benefit, and raise more revenue from high earners.
The short answer: treat the bill as a policy signal, not as money you can spend. The current Social Security COLA remains governed by existing law, and the official 2027 COLA will not be known until the government has the third-quarter inflation data it needs.
What the bill would change
The proposal has several moving parts. It would raise benefits by changing the benefit formula, improve the annual COLA by using a measure meant to better reflect older adults' expenses, and create a stronger minimum benefit for long-career workers with low wages.
The Senior Citizens League, a seniors advocacy group, summarized the reintroduced bill as including a 2 percent benefit increase, a minimum benefit equal to 125 percent of the federal poverty line, and a switch toward the Consumer Price Index for the Elderly. The group also said the bill would expand payroll-tax revenue above $400,000 and could extend the program's trust-fund life if enacted.
What is already current law
For now, the official Social Security Administration number is the one that matters for checks. SSA says Social Security and Supplemental Security Income benefits increased 2.8 percent for 2026, with the Social Security increase beginning with benefits payable in January 2026.
SSA also explains that COLAs are based on the Consumer Price Index for Urban Wage Earners and Clerical Workers, known as CPI-W. The agency compares the average CPI-W for the third quarter of the current year with the third-quarter average from the last year in which a COLA took effect, then rounds the increase to the nearest tenth of a percent.
Why people are searching now
The search interest is understandable. Retirees are watching inflation, lawmakers are debating the trust fund's long-term shortfall, and advocacy groups are publishing early 2027 COLA estimates. The Senior Citizens League said on July 14 that its model still projected a 3.8 percent 2027 COLA, one percentage point above the 2026 increase.
That estimate is not an official benefit change. It is a forecast that can move as inflation, interest rates, and labor-market data change. The official 2027 COLA will depend on third-quarter 2026 inflation readings, so a household budget should leave room for a different final number.
Check these five details before planning around it
- Bill status: A proposal can shape the debate without becoming law. If the bill is still in committee, your check is not changing because of it.
- Effective dates: Look for when any benefit increase would begin, not just the headline percentage.
- COLA formula: Current law uses CPI-W. A bill that uses a senior-focused index would need to pass before it changes benefit math.
- Your benefit type: Retirement, survivor, disability, and SSI benefits can be affected differently by related rules and notices.
- Tax and income tradeoffs: Revenue provisions aimed at high earners do not tell every beneficiary what their own tax bill or net income would be.
What to do now
Use official SSA notices and your my Social Security account for current benefits. If you are building a 2027 budget, run more than one scenario: one with the latest official 2026 payment, one with a cautious inflation adjustment, and one with no legislative change at all.
People near retirement should be especially careful about claim-age decisions. A larger proposed COLA or benefit formula may sound reassuring, but claiming early, working while receiving benefits, Medicare premiums, taxes, and household longevity can matter more than a bill that has not passed.
The practical takeaway is not to ignore the Social Security 2100 Act. It is to read it in the right category. The bill shows what some lawmakers want to change; SSA notices and enacted law show what beneficiaries can rely on today.
