TSP Spillover Contributions

Spillover contributions are made in conjunction with regular TSP contributions. There is no special form for spillover contributions. For more information on entering TSP contributions, see Thrift Savings Plan.

To be eligible to make spillover contributions, the following conditions must apply:

• The employee must be at least age 50 years or older during the calendar year in which the spillover contributions are made (even if the employee becomes age 50 on December 31 of that year).
• The employee must be currently employed and in a pay status (contributions are made through payroll deductions).
• The employee must be making regular contributions to a civilian or uniformed services TSP Thrift Savings Plan account (or both) and/or an equivalent employer plan (401(k) 403(b), or 408 plan) that equals the maximum allowed by IRS Internal Revenue Service.

Eligible employees may contribute up to the annual maximum dollar amount allowed by the IRS Internal Revenue Service elective deferral limit.

Since spillover contributions are supplemental, they do not count against the IRS Internal Revenue Service elective deferral limit. However, the combination of regular and spillover TSP Thrift Savings Plan contributions cannot exceed the total IRS Internal Revenue Service contribution limit for the year.

Contributions spilling over toward the catch-up limit will be matched, but only up to the 5% of salary to which participants are already entitled.

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

Spillover contributions may 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 spillover contributions.
