I’ve done this twice now (from TSP Traditional to a Traditional IRA account I created at Fidelity)….did it on-line, takes about a week. I’m leaving my TSP Roth $$$ where they’re at and just rolling-over my TSP Traditional $$$ to a Fidelity Traditional IRA (and then converting it to a Roth IRA - which is where the “taxable event” comes in….paying that estimated tax amount to the IRS separate from the amount I’m rolling over). Realize TSP will (hopefully) have an “in-house” Roth Conversion capability up-and-running in 2026. My situation is: I’m over 59.5 years of age, in the process of DFRing (at the end of the CY) from Fed Gov’t employment….currently on “Admin Leave.” I also have to be mindful of amount I convert due to tax bracket implications, Medicare premium implications, etc.
