Malaysia E-Invoicing: Guidelines, Requirements, Timeline and Exemptions

Malaysia has entered a decisive phase of digital tax transformation with the nationwide rollout of mandatory electronic invoicing. The Inland Revenue Board of Malaysia (IRBM) is leading this shift through the MyInvois platform, operational since August 2024, expanding across all taxpayer groups through a structured multi-year plan.

What an E-Invoice Means in Malaysia

An E-invoice is a structured digital document generated in UBL 2.1 XML or JSON format and transmitted to the IRBM for instantaneous validation. Once validated, it receives a unique identification number and QR code. The validated invoice becomes the official legal proof of supply.

Core Requirements

1. XML or JSON format aligned with UBL 2.1 standard
2. Submission via MyInvois Portal or API integration
3. Digital signing using IRBM-issued certificate
4. 55 mandatory data fields
5. Unique identification number and QR code
6. 72-hour correction and rejection window

Implementation Timeline

1. Phase 1 (Aug 2024): RM100M turnover
2. Phase 2 (Jan 2025): RM25M–RM100M turnover
3. Phase 3 (July 2025): RM5M–RM25M turnover
4. Phase 4 (Jan 2026): RM1M–RM5M turnover
5. Phase 5 (July 2026): All other businesses

Businesses with revenue below RM500,000 are exempt.
