e-Invoicing in Malaysia: A Complete Guide For Your Business

In March 2023, the Inland Revenue Board of Malaysia (IRBM) introduced mandatory e-invoicing in Malaysia, requiring all registered businesses to generate e-invoices for B2B, B2G, and B2C transactions.

The first phase began on 1 August 2024 for businesses with turnover exceeding RM 100 million, and phase 2 began on 1 January 2025 for companies exceeding RM 25 million. These businesses now submit e-invoices to the IRBM using the UBL 2.1 format (XML or JSON) through the MyInvois portal or via direct API integration.

Recent Update (5 June 2025): Revised e-Invoice Implementation Timeline

The Inland Revenue Board of Malaysia (IRBM) has updated the e-Invoice implementation timeline that introduces more categories and extends deadlines for smaller enterprises.

• 1 July 2025: Businesses with annual turnover between RM5 million and RM25 million.
• 1 January 2026: Businesses with annual turnover between RM1 million and RM5 million.
• 1 July 2026: Businesses with annual turnover up to RM1 million.

What is an e-Invoice?

An e-invoice is a digital record of a transactional exchange between a seller (supplier) and a purchaser (buyer), which goes through the government portal in real time for validation and recordkeeping.

e-Invoice Malaysia would contain 55 fields with details of the transactions such as seller & buyer details, item description, quantity, price, tax, total amount, payment details, etc. Successfully validated and generated e-invoices would also have a Unique Identification Number (UIN) and QR Code, which is generated by the MyInvois Portal, enabling online validation of the invoice.

e-Invoice New Implementation Timeline in Malaysia

The e-Invoicing system in Malaysia is being rolled out in phased manner based on the turnover. Below is the updated Malaysia e-invoice implementation timeline from the latest guidelines:

e-Invoicing Process in Malaysia

The steps to generate an e-invoice in Malaysia vary depending on the e-invoicing model (API or MyInvois Portal) and whether the transaction is B2B or B2C. However, the majority of the process remains consistent. 

Here is a general overview:

e-Invoicing Process for B2B Transactions

e-Invoicing Process for B2C Transactions

Suppliers must issue e-invoices for all B2C transactions. However, many buyers, particularly end consumers and specific businesses, do not need an e-invoice. Therefore, the generation of e-invoices for B2C transactions varies based on the buyer's requirements:

• When the Buyer Requests an E-Invoice: Suppliers gather details from the buyer/consumer and generate e-invoices in real-time, similar to B2B e-invoices.
• When the Buyer Does Not Require an E-Invoice: The IRBM allows suppliers to consolidate transactions with buyers who do not need an e-invoice into a monthly consolidated e-invoice.

The process is clearly explained in the chart below for Malaysia B2C e-Invoicing.

e-Invoicing Model in Malaysia

In Malaysia, companies can choose from the following transmission modes to report e-invoices known as e-invoicing models

MyInvois Portal

The MyInvois Portal allows users to generate e-invoices manually, either one at a time or in bulk by uploading a spreadsheet in a predetermined format. This portal is ideal for Micro, Small, and Medium-sized Enterprises (MSMEs) or companies with lower transaction volumes due to the need for manual data entry. 

The portal was made live by the IRBM on June 28, 2024, offering both testing and production environments. It can be accessed at preprod-mytax.hasil.gov.my or mytax.hasil.gov.my.

Application Programming Interface (API)

Businesses can integrate their ERP, billing, or accounting systems with the MyInvois system through an API. This integration enables the automatic generation, sending, receiving, and correction of e-invoices directly through their systems, making it possible to handle large volumes of transactions in real-time. 

Recognizing the complexity of this integration, the Lembaga Hasil Dalam Negeri (LHDN) has introduced the e-invoice Malaysia Software Development Kit (SDK).

Type of e-Invoices in Malaysia

The below documents must be issued in electronic format under Malaysia e-Invoice:

• Invoices: It is generally used to record transactions between supplier and buyer. Invoices also include a self-billed invoice issued for tracking expenses.
• Credit notes: A credit note is a document issued by sellers to make corrections to an e-Invoice issued previously mainly to lower the original invoice's value without returning money to the Buyer. It is generally used to adjust errors, apply discounts, or account for returned items. 
• Debit notes: In contrast to credit notes, debit notes are issued to record additional costs related to a previously issued e-Invoice.
• Refund notes: A refund e-Invoice is an official document issued by a Seller to record refund issued to the Buyer.

LHDN has released guidelines outlining which entities, individuals, and businesses are required to adhere to e-invoicing rules, as well as those exempt from them.
