Q. I understand that a federal civilian employee under FERS can make $52,000 a year to the Thrift Savings Plan. I know that the $17,500 regular contribution and the $5,500 catch-up contribution totaling $23,000 can be put into the Roth TSP. How much of the overall $52,000 limit can be put into the Roth TSP, and how would one contribute to the Roth TSP above the $17,500 and $5,500 limits?
A. You misunderstand the limits. The $17,500 and $5,500 limits are the total deferral limits to either the regular or Roth TSP.
