VCP conversion to Roth


Q. I am 66 years old and plan to retire in 2014, at which time I would transfer (convert) my Voluntary Contributions Program monies directly into a newly created Roth IRA. However, I have an existing (non-TSP) Traditional (substantial) IRA (never taxed), and know the Internal Revenue Service will aggregate my Traditional IRA balance for purposes of determining the taxability of this VCP-to-Roth conversion.

If, prior to retirement, I (in 2013) transfer (direct rollover) my Traditional IRA into my existing Thrift Savings Plan account, will those monies now be considered 401(a), and therefore, making my subsequent VCP-to-Roth conversion occur with few tax implications?

A. As I understand the rules, your TSP balance will not be subject to aggregation for the purpose of determining the taxability of your VCP-to-Roth IRA conversion, but you should consult a CPA before going down that path. You may also want to fill in a pro-forma IRS Form 8606 to see how it will look. This is the form used to calculate your tax liability on conversions. Notice that it does not mention an employer-sponsored plan like the TSP anywhere.
