Each October, the Social Security Administration (SSA) announces cost-of-living adjustments based on changes in national average wages. These adjustments take effect the following January.
Based on available data, on Oct. 13, the SSA communicated the maximum amount of wages subject to Social Security tax for 2018 to be $128,700, an increase from $127,200 in 2017.
However, due to additional information received later that month, the SSA announced a revised amount of $128,400 – or less than $300 originally reported – on Nov. 27.
In addition, the SSA’s revision impacts the “bend points” – that is, figures used in the computation of Social Security benefits – for primary insurance and the family maximum.
Employer responsibility
For 2018, an employer must withhold the following from employee wages:
- 6.2% Social Security tax on the first $128,400 of employee wages (maximum tax is $7,960.80; i.e., 6.20% × $128,400), plus
- 1.45% Medicare tax on the first $200,000 of employee wages, plus
- 2.35% Medicare tax (regular 1.45% Medicare tax + 0.9% additional Medicare tax) on all employee wages in excess of $200,000.
These rates and wage limits will be updated in the Paycom system effective Jan. 1, 2018. For more information, visit the Social Security website.
