2017 Social Security Wage Base


The Social Security Administration announced that the wage base for computing the Social Security tax (OASDI) in 2017 will increase to $127,200, which is up from $118,500 in 2016.

The Social Security Act provides for an automatic increase in Social Security and Supplemental Security Income (SSI) benefits if there is an increase in the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W).

The Federal Insurance Contributions Act (FICA) imposes two taxes on employers, employees, and self-employed workers—one for Old Age, Survivors and Disability Insurance (OASDI is commonly known as the Social Security tax), and the other for Hospital Insurance (HI is commonly known as the Medicare tax).

For 2017, the FICA tax rate for employers is 7.65% each: 6.2% for OASDI and 1.45% for HI.

For 2017, an employee pays all of the following:

  • 6.2% Social Security tax on the first $127,200 of wages

  • The maximum tax is $7,886.40 (6.2% of $127,200)

  • 1.45% Medicare tax on the first $200,000 of wages

  • $250,000 for joint returns

  • $125,000 for married taxpayers filing a separate return

  • 2.35% Medicare tax (regular 1.45% Medicare tax + 0.9% additional Medicare tax) on all wages in excess of $200,000

  • $250,000 for joint returns

  • $125,000 for married taxpayers filing a separate return

For 2017, the self-employment tax imposed on self-employed people is:

  • 12.4% OASDI on the first $127,200 of self-employment income, for a maximum tax of $15,772.80 (12.40% of $127,200)

  • 2.90% Medicare tax on the first $200,000 of self-employment income

  • $250,000 of combined self-employment income on a joint return

  • $125,000 on a separate return

  • 3.8% (2.90% regular Medicare tax + 0.9% additional Medicare tax) on all self-employment income in excess of $200,000

  • $250,000 of combined self-employment income on a joint return

  • $125,000 for married taxpayers filing a separate return

There is a maximum amount of compensation subject to the OASDI tax, but no maximum for HI.
