Guide to e-Invoicing in Malaysia: Everything You Need To Know
Following the Inland Revenue Board of Malaysia’s (IRBM) announcement in May 2023 regarding the implementation of e-invoicing in 2024, the IRBM released updated e-Invoice Guidelines (Version 2.3), Specific Guidelines (Version 2.1), and SDK (Version 1.0) on their website on 6th April 2024.
The introduction of e-invoicing aims to support the growth of Malaysia’s digital economy and improve the efficiency of the country’s tax administration. By replacing traditional paper invoices, e-invoices will streamline financial transaction recording and enable real-time data collection.
To further promote the digital economy, the government will implement e-invoicing in phases to enhance the overall efficiency of Malaysia’s tax administration.
What is an e-Invoice?
An e-invoice is a digital record of a transaction between a seller (supplier) and a purchaser (buyer), processed through the government portal in real time for validation and record-keeping.
The e-Invoice in Malaysia includes 55 fields containing transaction details such as seller and buyer information, item description, quantity, price, tax, total amount, payment information, and more. Once validated and generated, the e-invoice will be assigned a Unique Identification Number (UIN) and a QR code by the MyInvois Portal, enabling online validation of the invoice.
What is the Timeline for Implementing e-Invoicing in Malaysia?
The implementation of e-invoicing in Malaysia began on 1st August 2024, initially applying to taxpayers with an annual turnover or revenue exceeding RM100 million. From 1st January 2025, the system will be extended to include taxpayers with annual turnovers or revenues between RM25 million and RM100 million. By 1st July 2025, e-invoicing will be mandatory for all taxpayers in Malaysia, regardless of their revenue or turnover.

The e-Invoicing Process in Malaysia
The process for generating an e-invoice in Malaysia differs based on the e-invoicing model (API or MyInvois Portal) and whether the transaction is B2B or B2C. Nevertheless, most of the steps in the process remain the same.

Types of e-Invoices in Malaysia
Under Malaysia’s e-Invoicing system, the following documents must be issued in electronic format:
Invoices
An invoice is typically used to document transactions between a supplier and a buyer. It serves as a formal request for payment for goods or services rendered. For example, a supplier selling medical equipment to a hospital would issue an invoice listing the items sold, quantities, unit prices, taxes, and the total amount due. Additionally, self-billed invoices are used to track expenses when a buyer issues an invoice to themselves on behalf of the seller.
Credit Notes
An invoice is typically used to document transactions between a supplier and a buyer. It serves as a formal request for payment for goods or services rendered. For example, a supplier selling medical equipment to a hospital would issue an invoice listing the items sold, quantities, unit prices, taxes, and the total amount due. Additionally, self-billed invoices are used to track expenses when a buyer issues an invoice to themselves on behalf of the seller.
Debit Notes
Debit notes are used to record additional charges or costs incurred after an e-invoice has been issued. These notes increase the original invoice value. For instance, if a buyer was initially invoiced for RM10,000 for machinery, but additional freight charges of RM500 apply, a debit note for the additional amount would be issued to the buyer.
Refund Notes
A refund note is issued by the seller to document the reimbursement of funds to the buyer. This typically happens when the buyer returns goods or overpaid on an invoice. For example, if a customer returns a defective product worth RM200, the seller would issue a refund note to acknowledge the repayment.
