Update to the original article: On October 13, 2017, the Social Security Administration (SSA) announced that the maximum amount of earnings subject to the Social Security tax (taxable wage base) was to increase to $128,700 in 2018, from $127,200 in 2017. This increase was memorialized in IRS Notice 2017-64 and was based on the national wage data available at the time. In late October, however, a payroll service filed approximately 500,000 corrected Form W-2s that resulted in changes to the calculations used to determine the 2018 taxable wage base. Based on this updated wage data, the SSA revised the taxable wage base for 2018 to $128,400. These changes are reflected below.
The Internal Revenue Service recently announced the cost of living adjustments (COLA) for 2018. These COLAs affect various contribution and deduction limits for qualified retirement plans, as well as the deductible contribution limits for traditional Individual Retirement Arrangements (IRAs).
Internal Revenue Code Section 415(d) requires that the Secretary of the Treasury annually adjust these limits for cost-of-living increases. IRS Notice 2017-64 contains the COLAs that will take effect January 1, 2018.
