Retirement Information for Active Members (MSRB)

Information for current employees in the Massachusetts State Employees' Retirement System.

Membership in the MSERS system is mandatory for nearly all state employees who are regularly employed on a part-time (minimum of half-time) or full-time permanent basis. If you are regularly employed in the performance of duties for the state you are considered a member-in-service. You remain a member-in-service until you separate from service by reason of retirement, failure of re-election or re-appointment, resignation or removal or discharge from your position or office that you hold.

Note: state law does not allow you to withdraw or borrow from your annuity savings account under any circumstance, including mortgage down payment, college education or hardship. The only way to access your annuity savings account balance is to leave state service.
