Q. Does contributing to the Roth TSP affect my Roth IRA annual contribution limits? Can I submit up to the limits of both in the same year ($18,500/year Roth TSP and $5,500/year Roth IRA) if I have a Roth IRA account in addition to my Thrift Savings Plan account?
A. Roth TSP contributions do not affect the limits on contributing to a Roth IRA.
