Social Security is a popular but expensive program.
With the trust fund facing depletion in just a few years, experts have suggested different ways to cut costs and make the program more sustainable, including raising the full retirement age or eliminating the payroll tax cap for high-income earners.

Now, the Committee for a Responsible Federal Budget (CRFB), a bipartisan nonprofit, is adding another innovative solution to the mix: limiting cost-of-living adjustments (COLA) for the highest-income earners (1).
In a white paper published in October that cites calculations by the Urban Institute, the organization says the proposed change “could be a rapid, thoughtful and progressive way to help restore solvency and put Social Security on a sustainable path.”
The proposal is still just that — a proposal. But the timing is becoming more urgent. The latest Social Security Trustees Report, released in June 2026, says the retirement trust fund is projected to run out of reserves in the fourth quarter of 2032. If Congress does nothing, incoming revenue would then be enough to pay just 78% of scheduled retirement benefits. The combined retirement and disability trust funds are projected to last until 2034, with 83% of scheduled benefits payable after reserves are depleted (2).
If implemented, this shift could make it difficult for some beneficiaries to sustain their purchasing power later in retirement.
And that matters because Social Security recipients are about to get another COLA (3). AARP’s latest estimate is 3.5%. The official adjustment is expected in October, after September’s inflation data is released (4).
Here’s a closer look at why this change is being proposed and how it could impact your retirement plans.
What is COLA?
COLA is a mechanism built into the Social Security system that helps protect beneficiaries from the impact of inflation.
Initially, these adjustments were done on an ad-hoc basis and needed congressional approval. But when inflation flared up in the 1970s, Congress enacted a provision to allow for automatic annual COLAs. Since then, the annual COLA is linked to the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), an official measure of the monthly price change in a basket of goods and services, such as food, energy and medical care.
