Senior Citizens League Cuts 2027 Social Security COLA Estimate to 3.6% From 3.9%

Q: Why might the upcoming 2027 Social Security adjustment quietly trigger a surprise payroll tax increase for higher-earning workers?

The 2027 Social Security adjustment could indirectly mean a payroll tax hike because the same October announcement that sets the COLA also updates the program’s maximum taxable earnings cap, and that cap is expected to rise. Social Security tax does not apply to all wages without limit. In 2026, the 6.2% employee tax applies only to the first $184,500 of earnings, with employers paying another 6.2%. For 2027, the wage base is widely projected to increase to about $190,200. If that happens, workers earning above the cap would pay Social Security tax on an extra $5,700 of wages. That translates into about $353.40 more in Social Security payroll tax for an employee at or above the cap in 2027, with employers paying the same additional amount. For self-employed people, who pay both shares, the increase would be about $706.80. It can come as a surprise because public attention is usually focused on the COLA benefit increase for retirees, not on the less-noticed wage-base adjustment affecting current workers. The two changes are announced together, but they affect different groups: retirees may get bigger monthly checks, while higher earners may see slightly smaller paychecks. The increase is not caused by the COLA formula itself. Rather, both changes are part of Social Security’s annual indexing process, with the taxable wage cap generally rising with national wage growth. The final 2027 figures are due from the Social Security Administration on Oct. 14.

TSCL now pegs the 2027 Social Security cost-of-living adjustment at 3.6%, trimming its estimate by 0.3 percentage point from May's 3.9% projection.
The annual COLA is set from the change in average third-quarter CPI-W versus a year earlier, and the Social Security Administration will publish the official 2027 figure on Oct. 14.
July CPI-W rose 3.4% from a year earlier, with gasoline up 24.6%, electricity 4.2%, food 3% and rent 2.9%, showing why fixed-benefit retirees still face pressure.
The 2026 COLA was 2.8%, and because adjustments reflect past inflation rather than current prices, recipients are being warned to prepare for further erosion in purchasing power.
