FICA's Bite: Wages Subject to Social Security Tax to Increase in 2013

News Updates

Instead of a raise, some employees will see their take-home pay shrink in 2013 due to higher Social Security and Medicare taxes.

The maximum amount of earnings subject to the Social Security tax (taxable maximum) increasedto $113,700 from $110,100 as of January 2013, the U.S. Social Security Administration (SSA) announced on Oct. 16, 2012.

Social Security and Medicare payroll withholding are collected together as the Federal Insurance Contributions Act (FICA) tax.

By January 1, U.S. employers should have adjusted their payroll systems to account for the higher taxable maximum under the Social Security portion of FICA, and notified affected employees that more of their paychecks will be subject to FICA.

Of the estimated 163 million workers who will pay Social Security FICA taxes in 2013, nearly 10 million will pay higher taxes as a result of the increase in the taxable maximum, according to the SSA, which has published FAQs about these changes.

The inflation-based increase in wages subject to Social Security withholding is separate from the scheduled expiration of the temporary 2-percentage-point cut of the federal Social Security tax that was part of an economic and jobs package enacted at the end of 2010 and subsequently extended through the end of 2012.

In 2013, with the higher income ceiling and the return to the 6.2 percent withholding rate, the maximum yearly Social Security tax withholding rises from $4,624.20 (4.2 percent on income up to $110,100) to $7,049.40 (6.2 percent on income up to $113,700).

As a result, even employees who receive salary increases for 2013 may see the size of their paychecks shrink next year, especially if their pay raise is less than 2 percent. Notifying employees that FICA taxes are increasing for 2013 and highlighting the value of the employer-provided benefits package can help stave off falling morale (see, for example, the SHRM Online article "Benefits Statements Can Spotlight Hidden Value.")

Medicare Tax Rises for Higher Earners

Unlike Social Security, the amount of compensation subject to the 1.45 percent Medicare FICA tax is uncapped. However, in 2013, the Medicare tax rate rises to 2.35 percent for single taxpayers with annual income of more than $200,000 and for married joint filers whose combined annual income exceeds $250,000, under a provision of the Patient Protection and Affordable Care Act.

Medicare Premium Hike May Offset Benefit Increase

In addition, the SSA announced that monthly  Social Security and Supplemental Security Income (SSI) benefits paid to nearly 62 million Americans will increase by 1.7 percent in 2013.

The 1.7 percent cost-of-living adjustment (COLA) begins with benefits that more than 56 million Social Security beneficiaries, and more than 8 million SSI beneficiaries, receive in January 2013. The Social Security Act provides how the annual COLA is calculated.

For many beneficiaries, however, their Social Security increase will be partially or completely offset by increases in Medicare Part B premiums, which typically are deducted from Social Security benefits. Medicare Part B premium costs for 2013 were to be subsequently announced, but estimates, including the 2012 Medicare board of trustees' annual report, indicate an increase is on the horizon.

"This reflects the growing trend of health-related expenses eating into retirement income," said Cathy Weatherford, president and CEO of the not-for-profit Insured Retirement Institute, in a media statement. She advised those currently employed to develop a retirement plan that includes a strategy to cover basic living expenses as well as medical expenditures.
