e-Invoicing in Malaysia

Malaysia will adopt an electronic invoice system beginning June 2024. Against this backdrop, the Inland Revenue Board of Malaysia (IRBM) issued the much-awaited E-Invoice Guideline Year 2023 (Guideline) on 21 July 2023 (updated 29 September 2023). The Guideline addresses the scope of implementation of the E-Invoice which comprises the simplified e-invoice concepts, step-by-step guidance on key aspects of E-Invoice, practical examples, and common questions regarding E-Invoice.

The mandatory use of E-Invoicing covers B2G, B2B, and B2C transactions. Furthermore, domestic and cross-border transactions can be included. Electronic invoices can be used by taxpayers voluntarily from January 2024. IRB will provide a free portal called MyTax for taxpayers to issue and receive invoices manually. Starting from 2027, B2C transactions will follow the obligation and use E-Receipts. It is expected that B2C transactions will follow the real-time reporting model. The following documents will be under the scope of the regulation:

  • Credit and debit notes

  • Invoices

  • Receipts

  • Cancellations

Overview of e-Invoice

To facilitate taxpayers’ transition to E-Invoice, Taxpayers can select the most suitable mechanism to transmit E-Invoice to Lembaga Hasil Dalam Negeri Malaysia (LHDNM), based on their specific needs and business requirements.

Overview of e-Invoice

LHDNM has developed two (2) distinct E-Invoice transmission mechanisms:


  • Enables individual generation through a comprehensive form and the option for batch generation through spreadsheet upload for processing multiple transactions.

  • Accessible to all taxpayers.

  • Suitable for micro, small, and medium-sized enterprises (MSMEs).

  • May not be efficient for large volumes of data.

  • Businesses that need to issue E-Invoice but API connection is unavailable.



  • Enables businesses to conveniently transmit high-volume of transactions.

  • Requires upfront investment in technology and adjustments to existing systems. API connection may be made directly to LHDNM or through intermediary technology providers.

  • Ideal for large taxpayers or businesses with substantial transaction volume.

Workflow of E-Invoicing

The figure below demonstrates an overview of the e-Invoice workflow from the point a sale is made or transaction is undertaken, and an e-Invoice is issued by the supplier via MyInvois Portal or API, up to the point of storing cleared e-Invoices on LHDNM’s database for taxpayers to view their respective historical e-Invoices.

LHDN e-Invoice Guideline

In this context, it is crucial to understand the workflow of e-invoicing in general.

1. Issuance of e-Invoice

When a sale or transaction is made (including e-Invoice adjustments), the supplier creates an e-Invoice and shares it to IRBM via MyInvois Portal or API for validation.


2. Validation of e-Invoice

IRBM validation is performed in real-time, ensuring that the e-Invoice meets the necessary standards and criteria.

Once validated, the supplier will receive a Unique Identifier Number from IRBM via MyInvois Portal or API.

The Unique Identifier Number will allow traceability by IRBM and will reduce instances of tempering with the e-Invoice.


3. Notification of validated e-Invoice

IRBM will inform both the supplier and buyer once e-Invoice has been validated via MyInvois Portal or APIs.


4. Sharing of e-Invoice

Upon validation, the supplier is obliged to share the cleared e-Invoice (embedded with a QR code) with the buyer.

The QR code can be used to validate the existence and status of the e-Invoice via IRBM’s official portal.


5. Rejection or cancellation of e-Invoice

Upon issuance of e-Invoice, a stipulated period of time is given to:

• Buyer to request for rejection of the e-Invoice

• Supplier to perform cancellation of e-Invoice

Rejection requests or cancellations must be accompanied by justification.


6. MyInvois Portal

Supplier and buyer will able to obtain a summary of the e-Invoice transactions via MyInvois Portal.

E-Invoice Implementation Timeline

E-Invoice will be implemented in phases to ensure a smooth transition. The roll-out of E-Invoice has been planned with careful consideration, taking into account the turnover or revenue thresholds, providing businesses with sufficient time to adapt. Below is the E-Invoice implementation timeline:

Timeline Malaysia B2B

e-Invoicing was initially expected to be implemented in phases beginning from 1 June 2024. However, acknowledging the complexities faced by businesses in the implementation of e-invoicing, the Government has deferred the mandatory implementation timeline for taxpayers with an annual turnover or revenue exceeding RM 100 million from 1 June 2024 to 1 August 2024. The mandatory implementation of e-invoicing for all other taxpayers will be in phases, beginning 1 July 2025.
