Ready Reserve
If you are a member of the Ready Reserve and you are contributing to both a uniformed services and a civilian TSP account as a FERS employee, the elective deferral and catch-up limits apply to the total amount of tax-deferred employee contributions and Roth contributions you make in a calendar year to both accounts.
Active Duty
If you are called to active duty and make tax-exempt contributions to the TSP while deployed in a combat zone, the sum of the employee and agency contributions to your civilian account as well as the tax-exempt contributions made to your uniformed services account cannot exceed the Section 415 (c) annual addition limit.
For the current year's limits as well as more information on tax-exempt and Roth contribution limits, visit Contribution Limits.
