Payroll officials at the Department of Defense say a software glitch is to blame for miscalculated retirement and Social Security deductions in some upcoming civilian paychecks.
The Defense Finance and Accounting Service reported that paychecks for the pay period ending May 4 might be off for some employees due to an error in newly installed software for its Defense Civilian Pay System, according to an email from the Civilian Human Resources Agency.
The error inserted 2012 year-to-date contribution totals for retirement programs like the Thrift Savings Plan and the Roth TSP, as well as Social Security, in place of 2013 numbers, meaning some accounts were shown to have hit their contribution limits early.
Those affected will see lower retirement contributions in paychecks arriving this week or no contributions at all. Their Social Security deduction, or OASDI, could be higher.
DFAS will send official notices to civilians affected in the next 10 to 14 days, with instructions on correcting the error, according to the email.
A DFAS spokesman said accounts will be corrected before the end of the next pay period. The service processes payroll for 1.2 million federal civilian employees
The contribution limit for the regular TSP and the Roth TSP in 2012 was $17,000. Social Security is taxed at 6.2 percent for the first $113,700 earned in a year.
