Your account balance will stay in your account where you can continue to defer taxes on this money and control your investments by using the investment choices available under the Plan.
NOTE: This is what will happen if you don’t make a choice when you retire (the Plan default).
Things to Consider
You can leave all of your money in the Plan up to age 70½. Taxes will apply when your taxable account balance is eventually paid to you.
NOTE: IRS rules require that you begin to take your money out of the Plan by April 1 of the year after you reach age 70½. The only exception to this is if you continue to work past age 70½.
