Malaysia is undergoing a major transformation in tax administration with the nationwide rollout of mandatory e-Invoicing under the Inland Revenue Board of Malaysia (LHDN). More than 1.275 billion e-Invoices have already been submitted, reflecting rapid adoption of the MyInvois system across businesses.
This initiative is part of Malaysia’s digital economy agenda under the 12th and 13th Malaysia Plans, aimed at improving tax compliance, increasing transparency, and driving end-to-end digitalisation of business transactions. The shift replaces traditional paper and PDF invoices with a real-time validated digital system.
Since its phased rollout in August 2024, e-Invoicing in Malaysia has been introduced based on turnover thresholds. By 2026, it will apply to most businesses with annual revenue above RM1 million. This guide explains the compliance requirements, rollout phases, invoice types, and key steps businesses need to prepare.
What are e-Invoices?
An e-Invoice is a structured digital document that records a transaction between a supplier and a consumer in a machine-readable format (XML or JSON).
Unlike traditional invoices, e-Invoices in Malaysia are:
- Submitted in real time to IRBM via the MyInvois system
- Validated before being legally recognised
- Issued with a Unique Identification Number (UIN)
- Required to follow a standardised 55-field data structure (37 mandatory fields)
Why is Malaysia Implementing Mandatory e-Invoicing?
Malaysia’s e-Invoicing framework follows global Continuous Transaction Control (CTC) tax models adopted in countries such as Italy, Brazil, and Singapore, where real-time invoice validation improves tax transparency and reduces revenue leakage in Malaysia.
E-Invoicing in Malaysia has been mandatory since August 2024, when the Inland Revenue Board (LHDN) introduced real-time electronic invoicing through the MyInvois system. The mandate applies to all transaction types, including B2B, B2C, and B2G, and is being implemented in phases based on annual revenue thresholds.
Key reasons include:
- Stronger tax compliance: Reduces errors and tax leakage through real-time reporting
- Digital transformation: Supports Malaysia’s national digital economy goals
- Greater efficiency: Cuts paperwork, speeds up invoicing, and simplifies audits
- Better transparency: Improves monitoring of business transactions across sectors
- Sustainability: Reduces paper usage and promotes eco-friendly operations
Who must comply with e-Invoicing in Malaysia?
Compliance is determined by annual turnover thresholds, with mandatory adoption rolled out in phases to allow businesses sufficient time to transition.
1. Businesses with turnover above RM 100 million
- Mandatory from 1 August 2024
- Includes large corporations and listed companies
2. Businesses with turnover above RM 25 million to RM 100 million
- Mandatory from 1 January 2025
- Covers mid-sized companies across sectors
3. Businesses with turnover above RM 500,000 to RM 25 million
- Mandatory from 1 July 2025
- Includes majority of SMEs in Malaysia
4. Micro businesses (below RM 500,000 turnover)
- Currently exempt or deferred, subject to future LHDN announcements
- Not yet in mandatory phase as of 2026 rollout structure
The Ministry of Finance in Malaysia has extended the mandatory e-Invoicing relaxation period, doubling the grace period from 12 months to 24 months. Businesses with annual turnover below RM1 million now have until 31 December 2027 to fully transition to the e-Invoicing system.
What are the different types of e-Invoices in Malaysia?
Malaysia’s e-Invoicing framework under LHDN recognises four main document types used to record and adjust business transactions:
1. Invoice
The primary document issued for every sale of goods or services. It captures transaction details including pricing, tax compliance, and total payable amount.
2. Credit Note
A credit note is issued when the original invoice value needs to be reduced. This usually happens in cases such as product returns, post-sale discounts, or billing errors. It effectively adjusts the original invoice downward.
3. Debit Note
A debit note is used when the original invoice value needs to be increased. This can occur if additional goods or services are provided after the invoice is issued, or if there was an undercharge in the original billing.
4. Refund Note
A refund note is issued when money is returned to the buyer. It formally records that a payment has been refunded, ensuring the transaction is properly documented within the e-Invoicing system.
What is the e-Invoicing Implementation Timeline in Malaysia?
Malaysia’s e-Invoicing rollout is structured in phases based on annual turnover, with each group given a defined start date and a relaxation period to support a smooth transition.
| Phases | Implementation Date | Targeted Taxpayers (Annual Turnover) | End of Relaxation Period |
|---|---|---|---|
| Phase 1 | 1 August 2024 | > RM100 million | 31 January 2025 |
| Phase 2 | 1 January 2025 | RM25 million to RM100 million | 30 June 2025 |
| Phase 3 | 1 July 2025 | RM5 million to RM25 million | 31 December 2025 |
| Phase 4 | 1 January 2026 | RM1 million to RM5 million | 31 December 2026 (extended) |
What is the Malaysia e-Invoicing Process in Malaysia?
The e-Invoicing process follows six key stages:
1. Issuance of e-Invoice
The supplier creates an e-Invoice for a sale or transaction and submits it to the Inland Revenue Board of Malaysia (IRBM) through the MyInvois Portal or API integration.
2. Validation of e-Invoice
IRBM performs real-time validation to ensure all mandatory fields, tax information, and compliance requirements are met. Once approved, the invoice receives a Unique Identification Number (UIN).
3. Notification of Validated e-Invoice
Both the supplier and buyer receive confirmation through the MyInvois Portal or connected systems that the invoice has been successfully validated.
4. Sharing of e-Invoice
The supplier shares the validated e-Invoice with the buyer. The invoice contains a QR code that can be used to verify its authenticity through the MyInvois platform.
5. Rejection or Cancellation
Buyers or suppliers may reject or cancel the e-Invoice within 72 hours of validation, provided valid reasons and supporting justifications are submitted.
6. MyInvois Portal Access
Both parties can retrieve, review, and verify e-Invoice information through the MyInvois Portal for compliance, audit, and recordkeeping purposes.
The e-Invoicing process in Malaysia depends on the transaction type (B2B or B2C) and the submission method (MyInvois Portal or API integration). However, the core workflow remains similar across all models.
-
e-Invoicing Process for B2B Transactions.
Invoice Creation: Supplier generates invoice via ERP or MyInvois portal
Submission to LHDN: Invoice is sent for real-time validation
Validation by IRBM: Tax and data fields are verified instantly
Approval & UUID Generation: A Unique Identifier Number and QR code are issued
Notification: Both supplier and buyer are notified
Invoice Sharing: Validated invoice is shared for accounting and bookkeeping
Cancellation Window: Rejection allowed within 72 hours (subject to rules)
-
e-Invoicing Process for B2C Transactions
For retail and consumer transactions:
- If requested, an e-Invoice is generated and validated in real time, similar to B2B
- If not requested, transactions may be consolidated into a monthly e-Invoice as allowed by LHDN guidelines
