BIR Revenue Regulations No. 26-2025: Implementing Rules for E-Invoicing

Overview

BIR Revenue Regulations No. 26-2025 establishes the detailed implementing rules and technical standards that govern the mandatory e-invoicing program introduced under prior BIR issuances. The regulation provides prescriptive guidance on invoice data formats, transmission protocols, system certification procedures, and the phased compliance schedule applicable to covered taxpayers.

This brief provides a factual summary based on publicly available BIR guidance.

Covered Entities

Under BIR Revenue Regulations No. 26-2025, the e-invoicing mandate applies to:

• All taxpayers previously identified under BIR RR 11-2025 (Large Taxpayer Service registrants)
• Value-Added Tax (VAT)-registered entities meeting gross sales thresholds specified in the regulation
• Exporters and entities engaged in cross-border transactions as defined by BIR

Taxpayers not yet covered by prior issuances should monitor BIR announcements for expansion of the mandate to additional segments.

Prescribed Data Format and Transmission Standard

BIR Revenue Regulations No. 26-2025 specifies:

• Invoice format: JSON-based electronic invoice schema conforming to the BIR's Electronic Invoicing System (EIS) technical specification
• Transmission channel: Secure API connectivity to the EIS; batch file upload is available as a transitional option for qualifying entities
• Validation: Pre-submission data validation against BIR field rules is mandatory; invalid invoices are rejected at the gateway
• Acknowledgment: Each accepted invoice receives a BIR-issued Unique Reference Number (URN) that must be retained

System Certification Requirements

Enterprise software used to generate and transmit invoices must undergo BIR-prescribed certification before production use. Key requirements include:

• Submission of system documentation and sample invoice output to the BIR for technical review
• Demonstration of end-to-end transmission capability in the BIR test environment
• Certification renewal upon material changes to the invoicing system

Compliance Timeline

BIR Revenue Regulations No. 26-2025 adopts a phased schedule. Covered taxpayers should refer to the official BIR publication for their applicable compliance date. Transitional concessions may apply for entities demonstrating good-faith implementation efforts within the prescribed window.

Record Retention

Covered entities must retain electronic invoice records and transmission logs for a minimum period as specified in the Tax Code and consistent with BIR audit access requirements.
