Social Security COLA reduction proposals: What changes are on the table and how could benefits be affected?
Several proposals modeled by the Social Security Administration’s Office of the Chief Actuary could reduce future annual cost-of-living adjustments, or COLAs, for millions of beneficiaries as policymakers consider options to improve Social Security’s long-term finances.
The proposals are not current law, and they do not mean Social Security benefits have already been cut. The SSA lists them as policy provisions and estimates their potential financial effects using the intermediate assumptions of the 2026 Trustees Report.
Proposal would reduce annual COLA by 1 percentage point
One option listed by the SSA’s COLA proposals page would reduce the annual COLA by 1 percentage point beginning in December 2027.
For example, if the COLA calculated under the current system were 3%, the increase would be 2% under this proposal.
The SSA’s 2026 solvency estimates project that the proposal would eliminate 46% of Social Security’s long-range actuarial shortfall and 44% of the projected annual shortfall in the 75th year.
A 0.5 percentage point cut is also being modeled
A separate option would reduce the annual COLA by 0.5 percentage point starting in December 2027, according to the Social Security Administration’s policy options list.
The SSA estimates that this option would eliminate 24% of the long-range actuarial shortfall and 23% of the projected annual shortfall in the 75th year.
Although smaller than the 1-percentage-point proposal, a reduced annual adjustment could have a cumulative effect because each future increase would be calculated from a lower benefit amount.
Chained CPI proposal could mean smaller increases
Another proposal would change the inflation measure used to calculate Social Security’s annual COLA.
Under the option outlined by the SSA, the COLA would be calculated using a chained version of the Consumer Price Index for Urban Wage Earners and Clerical Workers, or CPI-W, beginning in December 2027.
The SSA estimates that this approach would reduce the annual COLA by about 0.3 percentage point on average. Its 2026 projections estimate that the proposal would eliminate 15% of the long-range actuarial shortfall and 14% of the projected annual shortfall in the 75th year.
The SSA also links this type of proposal to earlier policy discussions and memoranda, including proposals associated with the Bipartisan Policy Center, the Fiscal Commission and previous federal budget proposals.
Higher-income beneficiaries could receive no COLA
The SSA also models a more targeted option that would change COLA calculations based on beneficiaries’ income.
Under the SSA’s proposed provision A9, beneficiaries below specified modified adjusted gross income thresholds would receive a COLA calculated using the chained Consumer Price Index for All Urban Consumersor C-CPI-U, beginning with the December 2028 adjustment.
For beneficiaries above the thresholds, the proposal would provide no COLA. The projected thresholds for December 2028 are $117,300 for single, head-of-household and married-filing-separate taxpayers and $234,600 for joint filers, with the amounts indexed after that date as described by the SSA.
Why these proposals matter
Social Security COLAs are designed to adjust benefits for changes in the cost of living. The SSA’s modeling shows that reducing those future adjustments could improve the program’s projected financial position, while also resulting in smaller benefit increases over time.
For now, these remain policy options modeled by the Social Security Administration. None of the proposals described above has been enacted into law, and Congress would have to approve legislative changes before the current COLA formula could be altered.
