Under MPF, all accrued benefits derived from mandatory contributions must be preserved until the retirement age of 65 or certain withdrawal conditions are met. Voluntary contributions do not necessarily need to follow the MPF rules and therefore can be withdrawn upon termination of employment subject to the plan rules set out by the employer.
For MPF exempted ORSO schemes, the arrangement will be different. Existing members who join the scheme before the MPF implementation date can withdraw accrued benefits upon termination of employment. However, for new members who join after the MPF implementation date, they are subject to a "Minimum MPF Benefits" rule and only benefit amounts exceeding this level can be withdrawn upon termination of employment.
