TSP "Catch-Up" Contributions

The Thrift Savings Plan (TSP) offers eligible participants the opportunity to make tax deferred catch-up contributions from their basic pay to their TSP accounts. These contributions are in addition to the regular employee contributions and do not count against the annual limit for tax deferred contributions. The catch-up contributions have an annual limit. The annual limit for tax deferred contributions and catch-up contributions can be located on the Army Benefits Center-Civilian (ABC-C) website: or the TSP website:

Employees who meet all of the following conditions are eligible to make catch-up contributions:

  1. Age 50 or older in the year the catch-up contributions are made (the participant's birthday can be as late as December 31 of that year)
  2. At work or on paid leave during the pay period in order to make contributions, and
  3. Contributing an amount that is within the Internal Revenue Code (IRC) elective deferral limit for regular TSP for the tax year
