Philippines Mandatory E-Invoicing: Deadline and Compliance Guide

Context

On 22 September 2026, the BIR issued Revenue Memorandum Circular No. 98-2026 to establish detailed operational rules for mandatory electronic invoicing compliance. This circular builds upon two foundational Revenue Regulations: RR No. 11-2025 (issued on 27 February 2025) and RR No. 26-2025. The primary objective is to ensure that covered taxpayers meet the 31 December 2026 deadline for mandatory electronic invoice issuance.

The regulatory framework aims to streamline the tax compliance process, reduce fraud, and enhance the efficiency of tax administration. The BIR has explicitly excluded Micro Taxpayers from the mandatory electronic invoice requirement, focusing instead on Small, Medium, and Large Taxpayers engaged in e-commerce or internet transactions, Large Taxpayers Service users, and those using Computerized Accounting Systems (CAS), Computerized Books of Accounts with Accounting Records (CBA), or other invoicing software.

What's Changing: The Two-Stage Authorization Process

Covered taxpayers must complete a two-stage authorization process before issuing compliant electronic invoices.

Stage 1: Permit to Issue Electronic Invoice (PTI)

The first stage involves obtaining a PTI Electronic Invoice from the BIR. This permit is a prerequisite for compliant electronic invoice issuance. The BIR has committed to completing the evaluation within 20 working days of application submission.

Stage 2: Electronic Invoicing and Sales Reporting (EIS) Certification

Within six months of obtaining the PTI, taxpayers must secure EIS Certification. This certification validates that their systems meet BIR technical requirements, ensuring that electronic invoices are generated in a structured electronic format capable of being electronically extracted and processed. PDFs, scanned images, and manually created invoices do not satisfy this requirement on their own.

Implications for Covered Taxpayers

The mandatory electronic invoicing requirement has significant implications for covered taxpayers.

Compliance Deadline

The deadline for mandatory electronic invoice issuance is 31 December 2026. Businesses must prioritize PTI applications immediately to meet this deadline, given the 20-working-day evaluation window and the proximity of the year-end deadline.

Technical Requirements

Electronic invoices must be generated in a structured electronic format capable of being electronically extracted and processed. This requirement underscores the need for taxpayers to invest in compliant electronic invoicing systems that meet BIR technical standards.

Exemptions

Micro Taxpayers are explicitly exempt from the mandatory electronic invoice requirement. However, Small, Medium, and Large Taxpayers engaged in e-commerce or internet transactions, Large Taxpayers Service users, and those using CAS, CBA with Accounting Records, or other invoicing software must comply with the new regulations.

Outlook and What to Watch

As of 4 October 2026, no superseding guidance has been issued, and the deadline remains in effect. Businesses should prioritize PTI applications to ensure timely compliance.

General Electronic Sales Reporting

General electronic sales reporting remains subject to separate BIR implementation rules and is not yet mandatory under the 31 December 2026 invoice issuance deadline. Taxpayers should monitor further BIR guidance on this aspect of tax compliance.

Continuous Monitoring

Taxpayers must continuously monitor BIR communications and updates to ensure ongoing compliance with evolving regulations. The BIR may issue additional guidance or amendments, which taxpayers must incorporate into their compliance strategies.
