title: Social Security Wage Base
context: In 2018, the Social Security Wage Base was $128,400 and the Social Security tax rate was 6.20% paid by the employee and 6.20% paid by the employer.[1]  A person with $10,000 of gross income had $620.00 withheld as Social Security tax from his check and the employer sent an additional $620.00. A person with $130,000 of gross income in 2017 incurred Social Security tax of $7,886.40 (resulting in an effective rate of approximately 6.07% - the rate was lower because the income was more than the 2017 "wage base", see below), with $7,886.40 paid by the employer. A person who earned a million dollars in wages paid the same $7,886.40 in Social Security tax (resulting in an effective rate of approximately 0.79%), with equivalent employer matching. In the cases of the $130k and $1m earners, each paid the same amount into the social security system, and both will take the same out of the social security system.
