Senior Citizens League Sees 3.6% 2027 Social Security COLA, Lifting Checks by Nearly $70

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.

A 3.6% 2027 COLA would raise the average retired worker’s monthly Social Security benefit by $69.75 to $2,007.28, according to the latest Senior Citizens League estimate.
July inflation drove the forecast: consumer prices rose 3.4% year over year, while TSCL said its model has stayed relatively steady despite sharp swings that took inflation from 2.2% in January to 4.4% in May.
If the estimate holds, it would be the biggest annual adjustment in four years and a step up from the 2.8% 2026 COLA, which increased average benefits by $56.
The official 2027 COLA will be announced Oct. 14 with the September CPI report, while independent analyst Mary Johnson currently estimates a slightly lower 3.4% increase.
