E-Invoice Phase 3 in Malaysia: Key Changes, Requirements, and Implementation

Malaysia’s e-invoicing phase 3 rollout begins on 1 July 2025, requiring businesses with RM5–25 million turnover to comply. This stage continues the country’s phased approach, giving smaller businesses later deadlines and transition support through relaxation periods.

Key takeaways:

• Phase 3 applies to businesses with RM5m–RM25m turnover from July 2025, with a relaxation period until Dec 2025.
• Smaller businesses fall into Phase 4 (Jan 2026) and Phase 5 (July 2026).
• E-invoices must follow UBL 2.1 format, validated in real time via MyInvois.
• Compliance requires 55 mandatory fields, digital recordkeeping for 7 years, and QR code/UIN validation.
• Relaxation allows consolidated invoices, simplified descriptions, and no penalties.

Updated Timeline for Phase 3

Under the revised IRBM announcement (6 June 2025), the total implementation is divided into 5 phases, with phase 3 timeline as follows

• 1 July 2025: Businesses with annual turnover between RM 5 million and RM 25 million must comply.
• Relaxation period: Until 31 December 2025.

Smaller businesses are shifted to later phases:

• Phase 4 (Turnover RM 1 million – RM 5 million): 1 January 2026 (relaxation until 30 June 2026).
• Phase 5 (Turnover Less than RM 1 million): 1 July 2026 (relaxation until 31 December 2026).
• Exemption: Businesses with an annual turnover below RM500,000 are fully exempt.
  This updated rollout ensures medium-sized enterprises transition in 2025, while micro and small businesses get more time to prepare.
  

Compliance Requirements Under Phase 3

While the e-invoice implementation date varies, the core principles of e-invoicing remain consistent across all phases. The compliance requirements for Phase 3 are similar to earlier phases but with some considerations for smaller businesses:

1. Mandatory E-Invoice Generation: Businesses must issue e-invoices for all B2B, B2C, and B2G transactions. Each e-invoice must include 55 mandatory fields, such as seller/buyer details, item descriptions, quantities, prices, tax details, and payment information.
2. Schema Compliance: E-invoices must follow the UBL 2.1 format (XML or JSON) as specified by IRBM. Businesses can integrate their existing accounting software with the MyInvois System or use middleware solutions for easier compliance.
3. Real-Time Validation: E-invoices must be submitted to the MyInvois System for validation. A Unique Identification Number (UIN) and QR code are issued for each validated invoice.
4. Recordkeeping: Businesses must retain digital copies of all e-invoices for at least 7 years and store them securely for audit purposes.

Relaxation Period and Key Concessions

To help smaller businesses transition smoothly, IRBM has introduced a relaxation period for Phase 3:

• 1 July 2025 – 31 December 2025 (for businesses with turnover between RM 500,000 and RM 25 million)
• 1 January 2026 – 30 June 2026 (for businesses with turnover below RM 500,000)

During this period, businesses can benefit from:

• Consolidated E-Invoices: Multiple transactions can be combined into a single e-invoice.
• Simplified Product Descriptions: More flexibility in describing goods/services.
• No Penalties for Non-Compliance: Businesses will not face penalties under Section 120 of the Income Tax Act 1967 during the relaxation period

How Businesses in Phase 3 Can Adopt E-Invoicing: When to Start Preparing?

With Phase 3 of Malaysia’s e-invoicing mandate approaching, businesses must begin preparations early to ensure a smooth transition. Here’s a step-by-step guide on when and how to get started:

Assess Your Current Invoicing System (Start Now): Identify whether your business uses manual invoicing (Excel/paper), basic accounting software, or an ERP system. Determine if your current system can integrate with MyInvois or if you need to generate e-invoice manually through MyInvois Portal (recommended for small businesses with less number of invoices).

Choose the Right E-Invoicing Model and Solution:  If using an ERP/accounting software, check the feasibility of direct API integration with MyInvois (although not recommended). Better opt for a middleware solution (like ClearTax) to simplify compliance. You can also use MyInvois portal for manual e-invoice generation.

 Test & Train Generate sample e-invoices and validate them via MyInvois Sandbox (test environment). Educate employees on:

• Generating & submitting e-invoices.
• Handling rejections/corrections.
• Managing QR codes and UINs.

Go Live Before Deadline: Start live e-invoicing by 1 July 2025 (relaxation until 31 Dec 2025). Full compliance during the relaxation period offers businesses in Malaysia to claim accelerated capital allowance benefit.

Why Middleware is Preferred Over Direct ERP Integration for Phase 3?

Unlike larger enterprises in Phases 1 and 2, many small businesses in Phase 3 may not have custom ERP systems. Instead, they often rely on:

• Standard ERP
• Basic accounting software (e.g., SQL, Excel-based systems).
• Manual invoicing processes.

For these businesses, middleware solutions (such as ClearTax or other IRBM-accredited providers) offer a more practical approach because:
