2018 Social Security Cost-of-Living Adjustment (article)

The Social Security Administration announced a 2.0 percent cost of living adjustment for 2018. 

The Social Security wage base in 2018 will increase to $128,700 from the 2017 wage level of $127,200.  The combined Social Security and Medicare tax rate remains at 7.65% - the Social Security portion is 6.2% on wages up to the applicable maximum taxable amount; the Medicare portion is 1.45% on all wages. 

As a reminder, the Affordable Care Act imposes an additional 0.9% Medicare tax on high wage earners, applicable on earnings in excess of $200,000 in a calendar year. 

Additional adjustments are included in the SSA’s Fact Sheet: 2018 Social Security Cost-of-Living Adjustments.
