Announced by the Social Security Administration (SSA) the 2017 Social Security Wage Base will be $127,200, which is an increase of $8,700 (or 7.3%) from $118,500 in 2016.
What is the wage base?
The Social Secuirty tax is officially known as the Old Age, Survivors and Disability Insurance (OASDI) tax. It shows up on an employee's pay stub like this...
The Social Security Wage Base is the maximum earned gross income on which a wage earner's Social Security tax may be imposed. For example, in 2010, the Social Security Wage Base was $106,800 and the Social Security tax rate was 6.20% - for both employees and employers. So a person who earned $10,000 in 2010 would pay a total of $620 in Social Security tax - and that amount would also be matched by his or her employer.
A person who earned $110,000 in 2010 would pay a total of $6,621.60 in Social Security tax. Because their earnings were more than the wage base limit of $106,800, they wouldn't pay any Social Security tax on the additional $3,200 in annual earnings. Similarly, a muli-millionaire would also pay $6,621.60 in Social Secuirty tax. The idea is that everyone pays the same amount into the Social Security system, and later everyone takes out the same amount from the Social Security system.
