TSP Catch-Up

TSP catch-up contributions are supplement tax-deferred employee contributions that employees can make to TSP beyond the maximum amount they can contribute through regular contributions. In 2019, employees could contribute up to $6,000 in catch-up contributions. The 2019 limit for catch-up contributions remains at $6,000.

To be eligible to make catch-up contributions, the following conditions must apply:

Eligible employees can contribute up to the annual maximum dollar amount allowed by the IRS elective deferral limit. Catch-up contributions have an annual IRS limit of $6,000 for 2019, which are subject to annual increases for inflation.

Since catch-up contributions are supplemental, they do not count against the IRS elective deferral limit. However, the combination of regular and catch-up TSP contributions cannot exceed the total IRS contribution limit for the year. For example, for 2019, TSP contributions cannot exceed $25,000 (i.e., the $19,000 elective deferral limit on regular TSP contributions, plus the $6,000 catch-up contributions limit).

Catch-up contributions apply to the year during which they are made, even if they are posted to the TSP account in the following year (i.e., employee contributions for the last pay date in December may not be posted until January, but will be counted toward the limit in December).

Catch-up contributions can only be made from the employee’s basic pay. Bonuses or special pay and incentive pay for members of the uniformed services, cannot be applied towards catch-up contributions.

Note: Matching contributions do not apply to catch-up contributions.
