2020 Social Security Wage Base Limit Increase Announced

October 15, 2019

The Social Security Administration announced the Social Security wage base limit will increase while the withholding tax rate will remain unchanged.

At a Glance


The Social Security Administration meets annually to discuss the impact of inflation and cost of living. Using the consumer price index (CPI-W), the SSA decides on policy changes to address the approaching year’s economic outlook. As a result, the SSA increased the wage base limit for 2020 and provided a cost of living allowance to benefit recipients.   

2020 Wage Base and Cost of Living Allowance Adjustments

The Social Security Administration announced that beginning January 2020 the Social Security wage base limit will be increased from $132,900 to $137,700. Additionally, Social Security and Supplemental Security Income (SSI) beneficiaries will receive a 1.6 percent cost of living allowance. The withholding tax rate remains unchanged at 7.65% / 15.30% (employee / self-employed) respectively. The additional 0.9% of Medicare taxes will continue being assessed against covered earned income of $200,000 ($250,000 married filing jointly) or more in 2020.
