2 Agencies at the same time

Hi. Okay lang po kaya pagsabayin ang 2 agencies?

Agency A: pays all government mandated contribution

Angency B: only pays SSS and PhilHealth

Okay lang po kaya kasi di naman po sila both nagbabawas ng tax? Magkaka problem po kaya yun? And malalaman po kaya yun ng Agency A pag nagbackground check sila?
