e-Invoice Malaysia

Malaysia’s tax office, the Inland Revenue Board of Malaysia (IRBM), made the decision to mandate e-invoicing in March 2023 with a phase-wise implementation plan. The goal of the Ministry of Finance with this move was to digitize and streamline tax administration operations in Malaysia.

The Malaysian government aimed to ensure the various benefits of e-invoicing for the country, such as :

  1. Fraud Prevention In Proforma Invoices (And Others)
  2. Improved Tax Collection
  3. Reduced Business Operation Costs
  4. Increased Ease Of Business
  5. Better Transparency
  6. Accurate and Digitally Documented Financial Transactions

However, the Inland Revenue Board of Malaysia (IRBM) postponed the e-invoice implementation date to October 2023, giving businesses time to understand and adopt the concept of e-invoicing into their operations.

But what must Malaysian businesses do in order to ensure their transition to e-invoicing is smooth and effortless? In this article, we will go over every aspect of e-invoicing in Malaysia to help you understand how it works, its regulations, and how to prepare for the transition.

What is E-invoicing in Malaysia?

An electronic invoice or e-invoice is a document that is electronically exchanged between
a supplier and a buyer through specialized e-invoice software. In Malaysia, the Inland Revenue Board of Malaysia (IRBM) specifies the electronic invoice format.

A valid invoice in Malaysia will contain 53 e-invoice mandatory fields, including seller & buyer details, item description, quantity, price, tax, total amount, payment details, etc. 

These fields are grouped into 9 categories :

  1. Address
  2. Business Details
  3. Contact Number
  4. Invoice Details
  5. Parties
  6. Party Details
  7. Payment Info
  8. Products / Services
  9. Unique ID Number

Also, the Malaysian government will use a Continuous Transaction Control (CTC) model for verifying sales invoices via the government’s API. A Tax Identification Number (TIN) introduced in 2022 will power the use of e-invoicing in Malaysia.

Once validated and approved by the Inland Revenue Board (IRB), a serial number will be shared with the supplier via email. With this approach, the Malaysian government aims to adopt a CTC system connected to the Peppol network.

E-invoicing Authority in Malaysia

The Inland Revenue Board of Malaysia (IRBM) holds regulatory authority over e-invoicing endeavors in the country. 

And the IRBM/Lembaga Hasil Dalam Negeri Malaysia has taken a proactive approach towards incorporating and solidifying e-invoicing in the country by creating a memorandum of understanding (MoU) with the Malaysian Digital Economy Corporation (MDEC). 

Transactions Covered Under e-invoice Malaysia

e-Invoicing in Malaysia applies to all commercial activities in the country including the sale of goods and services. The official mandate by the Inland Revenue Board of Malaysia covers the following types of transactions:

Business-to-Business (B2B)

B2B invoicing through an electronic medium enables hassle-free payments, effortless invoicing, and better operational efficiency for all business-to-business transactions.
A well-developed B2B invoicing software can help a business improve productivity and cash flows by automating multiple time-consuming and manual tasks.

Business-to-Customer (B2C)

E-invoicing for B2C business transactions helps simplify invoicing for businesses regularly dealing with individual customers. However, sellers are not obligated to issue e-invoices to customers in the B2C scenario. They can provide a traditional invoice or receipt as well.

Be that as it may, after a certain period, sellers are required to aggregate all the issued invoices and receipts to generate a consolidated e-invoice.

Business-to-Government (B2G)

While the flow of e-invoicing in B2G is similar to that of B2B, it offers the benefits of
e-invoicing for transactions between businesses and government establishments/organizations.

E-invoicing Models in Malaysia

There are 3 e-Invoice model in Malaysia to report/transmit tax invoices to the IRBM, depending on the requirements of a business such as volume and customization.

  1. The MyInvois Portal
  2. Application Programming Interface (API)

The MyInvois Portal

The MyInvois Portal is a web-based platform provided and hosted by IRBM/Lembaga Hasil Dalam Negeri Malaysia (LHDN). It is a free portal for uploading invoices and a perfect option when connecting to APIs for e-invoice is an obstacle.

Application Programming Interface (API)

When the requirement includes large volumes of invoices, the API proves to be a more suitable option for e-invoice transmission. It allows direct transmission between the MyInvois System and the system used by taxpayers. API for e-invoicing in Malaysia is a great option for large enterprises with higher invoice volume and integration needs.

Peppol Service Providers

Using API integration through a PEPPOL service provider, Malaysia’s and cross-border suppliers can transmit e-invoices to LHDNM. It would enable them to benefit from the interoperability facilitated by PEPPOL.

Evaluate Existing Accounts Receivable (AR) Billing Procedures

Before transitioning to e-invoicing, it's crucial to thoroughly understand your existing Accounts Payable and Account Receivable (AR) billing procedures. Evaluate whether the timing of e-invoice issuance aligns seamlessly with the submission of e-invoice data to the Inland Revenue Board (IRB).

This assessment ensures that your AR billing processes are synchronized with e-invoicing requirements. It will reduce disruptions and ensure compliance with regulatory obligations. Also, consider streamlining AR processes where necessary to optimize efficiency and accuracy in e-invoice submission.

Evaluate and Plan Your International Transactions

When dealing with foreign customers, it's necessary to have a proper plan for self-issuing
e-invoices for international transactions. You must inspect and evaluate how your system currently manages these transactions to identify any potential challenges or areas for improvement.

Ensure that your system complies with international invoicing standards and regulations, considering factors such as currency conversion, language requirements, and cross-border tax implications.

Plan a Strategic Collection of Mandatory E-invoice Data

To ensure regulatory compliance with e-invoicing requirements, it's crucial to develop a comprehensive strategy for collecting essential data fields. This includes but is not limited to a unique identification number, name, and address. You must also collect other crucial information mandated by IRBM to facilitate seamless e-invoice processing and compliance verification.

Explore methods for securely storing and managing collected data to safeguard sensitive information and uphold data privacy standards.

Consequences of Not Generating E-invoices in Malaysia

Failing to comply with the e-invoicing mandate by IRBM can lead to penalties and legal actions in some cases. The Malaysian Income Tax Act considers the failure to generate e-invoices a criminal offense.

Hence, the e-invoicing Malaysia penalty ranges from RM 200 to RM 20,000 and in some extreme cases, imprisonment for up to six months. Some parties may face both the penalty and imprisonment.

Such strict regulations by the Malaysian government represent their dedication to improving transactional efficiency in the country. In short, every business conducting the sales of goods or services must generate an e-invoice.


The transition to GSTHero e-invoicing in Malaysia represents a significant shift towards modernization and efficiency in tax administration and business operations. The decision by the Inland Revenue Board of Malaysia (IRBM) to mandate e-invoicing underscores the government's commitment to leveraging technology for fraud prevention, improved tax collection, reduced operational costs, and enhanced transparency.

It's imperative for organizations to proactively prepare for the e-invoicing mandate. They must prioritize compliance with e-invoicing guidelines to avoid penalties and legal repercussions. 

By embracing e-invoicing and investing in the necessary resources and expertise, businesses can not only comply with regulatory requirements but also unlock benefits such as improved efficiency, accuracy, and competitiveness in the digital landscape.
