Benefits of the MIT 401(k) Plan
When you enroll in and contribute to your 401(k) account, you are 100% vested. You fully own your contributions, MIT's matching contributions, and all interest earned on the investments you choose through the Plan.
In addition, you receive the following tax benefits when you contribute to your MIT Supplemental 401(k) account:
- Your contributions are not subject to federal or Massachusetts state income taxes until you withdraw money from your 401(k) account.
- Any ongoing interest you accrue through your 401(k) investments is not subject to federal or state income taxes until you withdraw money from your 401(k) account.
Contributing to Your MIT 401(k) Account
You contribute to your 401(k) account through deductions from your MIT pay. Your contributions are sent to Fidelity Investments at the end of each pay period. You may contribute as little as 1% and as much as 95% of your salary (within federally prescribed limits) after amounts for Social Security and Medicare taxes and health and dental insurance have been subtracted. You may start, stop, or change your deferral or investment elections at any time.
Federal law limits the amount of your pay each year that may be recognized for determining your allowable contribution. In 2015, MIT can consider only the first $265,000 of pay for calculating your allowable contributions. This means that if your annual compensation exceeds $265,000, MIT Payroll will take 401(k) deductions from your pay until your pay for the year reaches $265,000, or one of the other 401(k) program limits has been reached (see Contribution Limits below).
- Federal law sets limits each year on how much you are eligible to contribute to a 401(k) account. Contributions you have made to other employers' retirement plans that count toward the annual maximum limits set by federal law will reduce the amount you may contribute to your MIT Supplemental 401(k) account.
- In 2015, participants under age 50 are permitted to contribute up to $18,000 annually and participants age 50 and over are permitted to contribute up to $24,000 annually.
What MIT contributes to your 401(k) Plan
- MIT matches your 401(k) deferral contributions dollar-for-dollar up to the first 5% of your MIT pay (subject to the annual limits specified by federal law).
- MIT only contributes a match during months in which you have made a contribution.
When contributions are invested in your 401(k) account
- Your 401(k) deferral contributions are sent to Fidelity following each pay period.
- MIT's matching contributions are sent to Fidelity Investments at the end of each month.
- Both your deferral contributions and the MIT matching contributions are invested according to your elections.
