Since 1 July 2022, 100 large taxpayers have been required to adopt e-invoicing as a result of the Tax Reform for Acceleration and Inclusion Act (TRAIN). These taxpayers are legally required to issue e-invoices/e-receipts and transmit them in JSON (JavaScript Object Notation) format to the government portal in real time, or within 3 days from the date of the transaction.

In accordance with the implementation timeline announced by the Philippines Bureau of Internal Revenue (BIR), all taxpayers will be required to transmit invoices to the government portal as of 2024.
