Q. I realize that the withdrawal of Roth earnings have different implications. But if I understand this correctly, the withdrawal of Roth IRA contributions can be done at any time without triggering a taxable event or penalty. Is the same true for the withdrawal of contributions from the Roth TSP?
A. You may withdraw Roth funds without tax or penalty if you’ve had a Roth IRA for at least five years (starting from Jan. 1 of the year you first contributed to a Roth IRA) and you are at least age 59½. The same rule applies to your Roth TSP funds. See the notice at https://www.tsp.gov/PDF/formspubs/tsp-536.pdf for more information.
