Q. Upon retirement, I’m considering transferring a portion of my Thrift Savings Plan balance in monthly payments directly into a Roth IRA. Since my TSP is pretax, I understand that taxes will need to be paid on these funds upon conversion to a Roth. I am in a state with no income tax on federal pensions and distributions from the TSP (North Carolina) and want to be sure that this transfer from my TSP to the Roth will be considered a TSP distribution for tax purposes, and therefore, subject to federal and not North Carolina taxes. Does the Office of Personnel Management issue a 1099R for such a transaction to generate the tax liability?
