Rolling IRA funds into TSP


Q. Is it possible and/or advisable to roll money I have from established IRAs (both traditional and ROTH) into my TSP account? Basically, paying into TSP over a number of years playing catch-up since I’m over 50. What kind of penalties/taxes would I be looking at?

A. It is possible and usually a good idea to transfer your IRA money into the TSP. Only pre-tax balances from IRA accounts are allowed; no Roth IRA money may be transferred. If your IRA account contains after-tax money from non-deductible contributions, you may transfer the pre-tax money to the TSP and then convert the after-tax money to a Roth IRA. Getting this done properly can be complicated, so you should consult a qualified and trustworthy adviser before taking any action.
