E-invoicing Malaysia: Everything you need to know

Discover how Malaysia’s phased e-invoicing mandate impacts your business and how to prepare with the IRBM’s MyInvois system.

Malaysia is undergoing a nationwide transition to mandatory e-invoicing, led by the Inland Revenue Board (IRBM). The rollout began in August 2024 and follows a phased timeline based on annual turnover thresholds, continuing through January 2026. All types of transactions—B2B, B2C, and B2G—are included in this mandate, making it essential for businesses operating in or with Malaysia to understand the requirements.

 

The core of the new system is MyInvois, the IRBM’s official platform for invoice validation. Before an invoice can be sent to a customer, it must first be submitted to MyInvois for real-time validation. Once approved, the platform returns a Unique Identifier Number (UIN) and a QR code, which must be attached to the final invoice shared with the buyer. Accepted formats include XML and JSON, structured according to the UBL 2.1 standard. This entire process—from generating to validating and delivering the invoice with its QR code—can be simplified and automated through B2Brouter, which handles all steps in seconds.

 

This guide outlines the key phases, required formats, and compliance procedures that businesses must follow under Malaysia’s new e-invoicing system.
