Social Security Wage Base 2018 Increase
The Social Security Administration (SSA) announced that the 2018 social security wage base will be $128,400; an increase of $1,200 from 2017. As in prior years, there is no limit to the wages subject to the Medicare tax; therefore all covered wages are still subject to the 1.45% tax. Wages paid in excess of $200,000 in 2018 will be subject to an extra 0.9% Medicare tax that will only be withheld from employees' wages.
The FICA tax rate will be 6.2% for 2018 up to the social security wage base. The maximum social security tax employees and employers will each pay in 2018 is $7,960.80.
