You can keep the money in the TSP after you leave your federal job to benefit from the low fees, or you can roll over the money into an IRA or a new employer's 401(k), 403(b) or 457.

However, you need to keep in mind that you will not be able to make additional deposits to your account once you are no longer part of the uniformed services or civil service. Advantages: The TSP is a great place to invest for retirement.
