2) the employer must file Form MAT-2 to the nearest SSS branch
Your employer should advance the maternity benefit to you in full within 30 days from the date you file your maternity leave application. Your employer may then apply for reimbursement of the advanced amount by filling up one copy of SSS Form MAT-2 (Maternity Benefit Reimbursement Application) and submitting it to the SSS branch where his records are active. The duly stamped copy of Form MAT-1 must also be presented.
Refer to page 2 of Form MAT-2 for the list of supporting documents that must be submitted together with the form.
