When to Enroll

The time for enrollment in the MIT Supplemental 401(k) Plan depends on whether you are paid monthly or weekly.

If you are paid on a monthly basis

  • You must enroll or make deferral changes by 4 p.m. ET on the 15th day of the month in order for the initial enrollment or deferral percentage change to take effect for that month's pay.
  • When you enroll, you should complete a 401(k) Plan Beneficiary Designation form so that, in the event of your death, your benefits are paid according to your wishes.

If you are paid on a weekly basis

  • Generally, you must enroll or make deferral percentage changes by 4 p.m. ET on Thursday in order to have the initial enrollment or deferral percentage change take effect for the following week's pay.
  • When you enroll, you should complete a 401(k) Plan Beneficiary Designation form so that, in the event of your death, your benefits are paid according to your wishes.

Receiving your Retirement Payments

You may choose to begin receiving retirement payments any time after your employment ends or you reach the age of 59½ and are permanently scheduled to work 50% or less of the normal full-time work schedule.

Federal law requires that you begin receiving payments by April 1 following the year in which you reach the age of 70½, unless you are actively employed by MIT. If you are not actively employed past age 70½, you must start receiving minimum required distributions (referred to as MRDs) or you will incur severe tax penalties if you fail to receive payments.

Keep Track of Your MIT 401(k) Account

  • Pay close attention to your quarterly 401(k) statements so that you can monitor your account.
  • Check on your account at any time by visiting Fidelity NetBenefits.
