Your money will roll-over in the account, that is why it is commonly known as roll-over account. Due to larger pool of asset size, retaining and merging accrued benefits in one consolidated personal account may save you additional fees and charges.
Your future contributions from new employers will go into the new employer's MPF scheme instead of the personal account.
No. Your employer cannot withhold your benefits accrued from mandatory contributions. It will be vested fully as your accrued benefits once they are paid to your trustee. However, for voluntary contributions paid by your employers, forfeiture of benefits will be subject to the governing rules of your scheme.
Under the regulations, the trustee is restricted from imposing any fees or financial penalties for the transfer of accrued benefits from one registered scheme to another or from one account to another within the same scheme. (except in the case of expenses incurred as a result of funds redemption)
After receiving your transfer request, your new trustee will notify your previous trustee for the transfer of your accrued benefits. Your previous trustee is required to transfer your accrued benefits to the new trustee within 30 days after such notice. A transfer statement will be issued to you stating the particulars. The new trustee of your personal account will also send you a confirmation stating the amount received from your previous scheme.
