Guide to e-Invoicing in Malaysia: Everything You Need To Know

Last updated on 11th May 2026.

Following the Inland Revenue Board of Malaysia's (IRBM) announcement in May 2023 on the implementation of e-Invoicing in 2024, IRBM has since issued multiple rounds of updated guidelines to keep pace with the phased rollout, all available on their website. 

The most current reference is the e-Invoice Specific Guideline Version 4.7, published on 20 April 2026, which covers detailed guidance across a wide range of transaction types including cross-border transactions, e-commerce, periodic billing, self-billed e-invoices, and agent or distributor arrangements. All businesses subject to e-Invoicing obligations should refer to Version 4.7 and the accompanying updated General FAQs (22 April 2026) as the authoritative sources for compliance.

What are e-Invoices?

An e-Invoice is a digital proof of a transaction between a supplier and a buyer. It eliminates the necessity for paper invoices by enabling businesses to generate and store machine-readable, digitised versions of invoices, facilitating streamlined processes for billing and payments. e-Invoices will be created in IRBM’s specified format (XML, JSON) and shall contain 55 fields (37 mandatory).

What is the e-Invoicing Implementation Timeline in Malaysia?


The Malaysian Inland Revenue Board (IRBM) has announced a phased implementation of e-Invoicing starting from 1 August 2024, gradually extending to all businesses with annual turnover or revenue above RM1 million, with Phase 4 businesses (up to RM5 million turnover) granted an extended interim relaxation period from 1 January 2026 to 31 December 2027.

The rollout is based on annual turnover thresholds, beginning with large taxpayers and moving down to smaller enterprises.

Businesses will be required to adopt e-Invoicing according to their size, as determined by their annual turnover or revenue, with the earliest groups expected to comply within 2024 and subsequent groups phased in based on turnover thresholds. Businesses with annual turnover below RM1 million are currently exempt, subject to specific group-related conditions.

Summary of e-Invoicing Implementation Phases:

  • 1 August 2024 – Taxpayers with annual turnover or revenue exceeding RM100 million
  • 1 January 2025 – Taxpayers with annual turnover or revenue between RM25 million and RM100 million
  • 1 July 2025 – Taxpayers with annual turnover or revenue between RM5 million and RM25 million
  • 1 January 2026 – Taxpayers with annual turnover or revenue up to RM5 million

Businesses with annual turnover or revenue of up to RM1 million remain outside the scope of mandatory e-Invoicing, subject to specific group-related conditions.


Important update for Phase 4 businesses (up to RM5 million turnover):

The interim relaxation period has been further extended to 31 December 2027, a total of two years. This was announced by Prime Minister Datuk Seri Anwar Ibrahim in April 2026 as part of a broader SME relief package. During this period, Phase 4 businesses may continue to use consolidated e-invoices and are not subject to penalties for non-compliance, provided basic requirements are met. 

Note: The legal mandatory implementation date of 1 January 2026 remains unchanged. Full penalty enforcement for Phase 4 businesses will begin on 1 January 2028.

What are e-Invoicing Transaction Types?

e-Invoicing applies to all taxpayers undertaking commercial activities in Malaysia. It will facilitate instant validation and storage of Business-to-Business (“B2B”), Business-to-Consumer (“B2C”) and Business-to-Government (“B2G”) transactions. It will also apply to certain non-business transactions between individuals. 

For certain B2C transactions where the end consumer does not need e-Invoices to support the transactions for tax purposes, suppliers are allowed to issue normal receipts/invoices based on current practices. 

Overview of e-Invoicing for Transactions with Buyers

Below is an overview of the process for Buyers who do and don’t require e-Invoices.

e-invoicing overview workflowScenarios of e-Invoicing Transaction with Buyers

Scenario 1: Buyer requires an e-Invoice

  1. Supplier obtains Buyer’s details 
    • For Malaysians: Either TIN or IC No. / MyTentera identification number / Both TIN & IC No./MyTentera identification no.
    • For non-Malaysians: Either TIN / Both TIN & Passport

  1. Supplier issues and validates e-Invoice with IRBM

  2. Supplier shares validated e-Invoice to Buyer

  3. Buyer may scan QR code to view e-Invoice validity

  4. Buyer will be able to substantiate the transaction for tax purposes.

Scenario 2: Buyer does NOT require e-Invoice

  1. Supplier issues normal receipts to Buyer (same as current practice). However, the Buyer can request for an e-Invoice within the month of the transaction (i.e. if a purchase was made on 15 September, the Buyer is allowed to request an e-Invoice up until 30 Sept) via web portal/mobile application created by Supplier.
  2. Supplier consolidated all receipts (where e-Invoices are not required by Buyers) on a monthly basis. The consolidated e-Invoice is to be issued and submitted for IRBM’s validation within 7 calendar days after month end. 

Who is Required to Comply with e-Invoicing in Malaysia?

All individuals and legal entities are required to comply with the e-Invoicing requirement, including:

  1. Associations;
  2. Body of persons;

Scenarios Requiring e-Invoices to be Issued

Proof of Income

Issued whenever a sale or other transaction takes place to recognise the income of taxpayers.

Proof of Expense

Purchases made or other spending by taxpayers, including returns and discounts. It can also be used to correct or subtract an income receipt in terms of the amounts documented. In certain cases, taxpayers may need to issue a self e-Invoice to document an expense such as foreign transactions.

Determination of Annual Turnover or Revenue 

  • Taxpayers with audited financial statements: annual turnover or revenue stated in audited financial statements for FY 2022.  

  • Taxpayers without audited financial statements: annual revenue reported in tax return for YA 2022.  

  • In the event of a change of accounting year end for FY 2022, taxpayer’s turnover or revenue will be prorated to a 12-month period.  

  • For new businesses or operations commencing from the year 2023 onwards, the e-Invoicing implementation requirement will be determined based on the applicable turnover thresholds and IRBM guidance in force at the relevant time. Notifications will be sent to taxpayers that are mandated to adopt e-Invoicing, in phases.

What are the e-Invoicing Models in Malaysia?

Two distinct e-Invoice transmission mechanisms are available:

a) A portal (MyInvois Portal) hosted by IRBM; and 
b) Application Programming Interface (API) into IRBM’s related systems. 

Taxpayers can select the most suitable mechanism to transmit e-Invoice to IRBM, based on their specific needs and business requirements. The key features of and considerations for each option are outlined below:


No.

Mechanism 

Key Features

Considerations

1.

MyInvois Portal
(hosted by IRBM) 

A portal hosted by IRBM as an option that is available to taxpayers at no cost

  • Accessible to all taxpayers

  • Suitable for MSMEs  

  • May not be efficient for large volume of data 

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

2.

Application Programming Interface (“API”)

(into IRBM’s related systems)


An API is a set of programming code that enables direct transmission between the taxpayers’ system and MyInvois System

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

  • Ideal for large taxpayers or businesses with substantial transaction volume

e-Invoicing Overall Workflow

  1. Issuance of e-Invoice

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

  1. Validation of e-Invoice

Real-time validation by IRBM is performed, ensuring necessary standards and criteria are met. Once validated, the supplier will receive a Unique Identifier Number via MyInvois Portal or API. 

  1. Notification of validated e-Invoice 

Both the supplier and buyer will be notified via MyInvois Portal or API once e-Invoice has been validated.

  1. Sharing of e-Invoice

Upon validation, the supplier is obliged to share the cleared e-Invoice (embedded with QR code) with the buyer. The QR code can be used to validate the existence and status of the e-Invoice via MyInvois Portal.

  1. Rejection or cancellation of e-Invoice 

Buyer/supplier may reject/cancel the e-Invoice with justifications within 72 hours from the time of e-Invoice validation.

  1. MyInvois Portal

Both supplier and buyer have the option to request and retrieve e-Invoice data via MyInvois Portal.
