2018 Contribution Limits and Other Updates for Payroll
The IRS and the SSA recently announced increases to limits that will affect 2018 payroll and withholdings. Please see the highlights below.
Social Security Wage Base for 2018:
The Social Security wage base will increase to $128,700, up from $127,200 in 2017. The maximum Social Security tax that employers and employees will each pay is $7,979.40 ($128,700 x 6.2%), and a self-employed person with at least $128,700 in net self-employment earnings will pay $15,958.80 for the Social Security part of the self-employment tax.
The Medicare component remains 1.45% of all earnings, and individuals with earned income of more than $200,000 ($250,000 for married couples filing jointly) will pay an additional 0.9% in Medicare taxes. An employer is required to withhold the additional Medicare tax on an individual even though they won’t owe the tax because they don’t meet the $250,000 threshold for joint filers. The taxpayer can claim credit for any excess withheld Medicare tax on their 1040.
