Social Security Tax and Wage Base
The Social Security Administration announced that the 2021 social security wage base will be $142,800, which is an increase of $5,100 from $137,700 for the 2020 calendar year.
The regular Medicare tax rate of 1.45% remains unchanged and applies to all income without a limitation for both the employee and employer portion. The Affordable Care Act additional Medicare tax of 0.9% remains unchanged. The additional Medicare tax applies to wages, other compensation, and self-employment income over certain dollar thresholds ($200,000 for single and $250,000 for married filing jointly). The additional Medicare tax only applies to the employee and not the employer. IRS regulations require an employer to withhold the additional Medicare tax on wages or compensation it pays to an employee in excess of $200,000 in a calendar year.
