To apply for Pag-IBIG contributions, you must first register through their official website or visit a Pag-IBIG branch. The contribution table, which outlines the amounts based on your salary, can also be found on the Pag-IBIG Fund's official site at pagibigfund.gov.ph. It’s important to ensure you’re aware of your contribution rate and the benefits it provides. If you have specific questions about your eligibility or need assistance, consider reaching out directly to Pag-IBIG or a licensed financial adviser.
