Q. There is around a $5,000 annual limit to a Roth IRA based on income and age. Does that limit apply to TSP? In other words, can I put all $17,500 plus the $5,500 catch-up contributions for those age 50 and older into the Roth TSP and pay taxes on it now, rather than later regardless of my income? I am a civilian over 50 years old in FERS.
A. The Roth IRA limit does not apply to Roth TSP contributions.
