What if you have two accounts? Great question! My wife separated from active duty and then worked a civil service job, so she has two TSP accounts; one military, and one from Federal service. The instructions are basically the same. If you are still active in the uniformed services or Federal service, you can still only change your address through your agency or service. Then just check the appropriate box on your Form TSP-9 for the agency or service in which you are no longer active. If you are no longer active in either the uniformed services or Federal service, then you can use one form to change your address on both accounts – just check both boxes when you send in your form, or update it online. Don’t forget about your ability to transfer your TSP. If you have since left Federal or military service, you may wish to consolidate your financial accounts to make it easier to plan for retirement or otherwise manage your money. If this is something you wish to consider, the be sure to review your options for rolling over a TSP account. Some options include rolling it into a 401k or other employer sponsored retirement plan, opening an IRA, or rolling it into a current IRA.
