The Bureau of Internal Revenue (BIR), a revenue service responsible for collecting tax revenues for the Government of the Philippines, has partially mandated e-invoicing in the country. It requires certain taxpayer categories to issue electronic invoices in a machine-readable format, such as JSON, through an ERP software integrated with BIR EIS. Businesses may also need PTT/EIS Certification, CAS/CBA integration, and API connectivity for electronic invoice issuance and transmission.
According to BIR Revenue Regulations No. 11-2025, certain taxpayers in the Philippines are required to issue electronic invoices in structured invoice data that can be electronically transmitted to the BIR. These taxpayers include those engaged in the export of goods & services, e-commerce, and classified as Large Taxpayers Service (LTS), along with the users of CAS, CBA, and certified invoicing software.
