Contribution limits for the TSP are the same as regular 401(k)s. Employees and employers using the TSP will have the same contribution limits as 401(k) plans.
An employee can defer up to $18,000 a year in 2016, plus a $6,000 catch-up deferral if the employee is over 50 years old. The employer can contribute up to a maximum total balance of $53,000 (or $59,000 if the employee is over 59 ½), including employee deferrals. There is a standard 1% employer flat contribution, and some Federal employees will also receive a match.
