On November 27, 2017, the Social Security Administration (SSA) announced that due to its receipt in late October 2017 of approximately 500,000 Form W-2 corrections for tax year 2016, it has now lowered the 2018 Social Security taxable wage base to $128,400, down from the $128,700 it originally announced on October 13, 2017. The employee and employer contribution rates remain the same from 2017 to 2018 at 6.2%.



The revised 2018 wage base of $128,400 is lower than the $130,500 projected in the July 2017 Annual Report of The Board of Trustees.



The Medicare tax rate for 2018 remains at 1.45% of all covered earnings for employers and employees. For wages in excess of $200,000, the Additional Medicare Tax of 0.9% applies to earned income of more than $200,000 ($250,000 for married couples filing joint). While employers are required to withhold the additional 0.9% on covered wages in excess of $200,000, there is no employer matching contribution.



Paylocity will revise these limits at the beginning of 2018 to meet the most current standards set by the SSA.
