Malaysia continues to move forward with the implementation of its e-invoicing system, which began progressively in August 2024 and has since been extended to new groups of taxpayers based on their annual revenue or turnover.
The latest significant update took place on 30 August 2026, when the Inland Revenue Board of Malaysia (HASiL) published version 4.8 of the e-Invoice Guideline, introducing new criteria regarding the scope of the requirement and increasing the exemption threshold applicable to certain small taxpayers.
Under the new criteria, taxpayers with annual revenue or turnover below 3 million Malaysian ringgit (RM) may be exempt from mandatory e-Invoice implementation, provided they meet the conditions established by HASiL.
The exemption does not depend solely on an individual taxpayer's turnover. Certain businesses linked to non-individual shareholders, holding companies, related companies or joint ventures whose annual revenue or turnover reaches or exceeds RM3 million may fall outside the exemption and therefore remain subject to e-Invoice requirements.
The new threshold also applies to businesses established between 2023 and 2025. For businesses commencing operations from 2026 onwards, implementation may be deferred where their expected revenue or turnover for the first year remains below the established threshold.
Malaysia updates its e-Invoice guidelines in 2026
Throughout 2026, HASiL has continued to update the e-Invoice implementation framework with new guidelines, transition measures and specifications designed to facilitate compliance for businesses and technology providers.
These measures include the e-Invoice Special Voluntary Disclosure Programme (PKPS), launched in July 2026 and available until 31 December 2027. The programme allows eligible taxpayers to regularise certain e-Invoice-related non-compliance in accordance with the conditions established by the tax authority.
HASiL has also progressively updated the documentation governing the operation of the system. The e-Invoice Guideline is currently at version 4.8, published on 30 August 2026, while the e-Invoice Specific Guideline reached version 4.9 on 7 September 2026.
These updates complement the FAQs, technical specifications and transition measures published by the tax authority and aim to provide greater clarity on the scope, operation and implementation of the MyInvois system.
Technical and detailed information on e-Invoicing in Malaysia
E-invoicing in Malaysia operates through MyInvois, the platform developed by HASiL to electronically manage and validate transactions carried out by taxpayers.
The system provides different mechanisms to facilitate the issuance of electronic invoices. Businesses can use the MyInvois Portal directly or connect their own business systems via API, an option particularly suited to organisations handling high transaction volumes and requiring greater automation.
HASiL has also introduced a range of clarifications to adapt the system to specific scenarios. These include rules applicable to transactions with government entities and specific requirements relating to sectors such as electricity and telecommunications.
For transactions with public-sector bodies, the system provides for the use of specific tax identifiers where necessary to ensure the correct issuance and validation of electronic invoices.
The tax authority has also developed MyInvois e-POS, a solution designed to facilitate the digitalisation and management of transactions for certain small businesses through tools integrated with the e-Invoice ecosystem.
Does the RM3 million exemption apply to all small businesses?
Not necessarily. Annual revenue or turnover is not the only criterion determining whether a taxpayer can benefit from the exemption.
HASiL establishes specific conditions for businesses linked to other taxpayers, for example through non-individual shareholders, holding companies, related companies or joint ventures. Where the relevant criteria are met, a business with individual turnover below RM3 million may still be subject to e-Invoice requirements.
Businesses belonging to corporate groups or related structures should therefore assess both their turnover and their corporate relationships before determining whether the exemption applies.
New MyInvois technical validations from October 2026
The evolution of MyInvois is also introducing changes to the technical rules that systems connected to the platform must comply with.
The MyInvois SDK update introduces new validation limits for certain fields used in electronic invoices. These include a maximum of 26 digits for certain monetary fields, both at invoice and line level, and a maximum of 12 characters for the PASSPORT identifier.
These rules are scheduled to enter the production environment on 23 October 2026. Once implemented, documents that do not comply with the new validation criteria may be rejected, meaning businesses and technology providers should review their MyInvois integrations in advance.
E-Invoice implementation timeline in Malaysia
Mandatory e-Invoice implementation in Malaysia has been introduced progressively, primarily according to taxpayers' annual revenue or turnover.
The implementation timeline establishes the following phases:
- More than RM100 million: mandatory from 1 August 2024.
- More than RM25 million and up to RM100 million: from 1 January 2025.
- More than RM5 million and up to RM25 million: from 1 July 2025.
- Up to RM5 million: from 1 January 2026.
However, following the update published on 30 August 2026, taxpayers with annual revenue or turnover below RM3 million may be exempt from e-Invoice implementation, provided they meet the conditions established by HASiL.
Turnover therefore remains one of the main criteria for determining the scope and implementation timeline, but it must be assessed together with the specific exemption rules, particularly where corporate or business relationships with other entities exist.
Malaysia's e-Invoicing model
Malaysia's e-invoicing model is based on a Continuous Transaction Controls (CTC) system in which invoices are submitted to the MyInvois platform for validation by HASiL.
The model allows businesses to generate and transmit their invoices through the MyInvois Portal or integrate their management systems directly with the platform via API.
The electronic invoice contains structured information about the transaction and, once validated by the tax authority, can continue to be exchanged between the supplier and buyer.
Malaysia's ecosystem also provides for the use of Peppol as a mechanism to facilitate the interoperable exchange of electronic invoices between businesses and systems.
What is the process for issuing and receiving electronic invoices in Malaysia?
The e-Invoice process in Malaysia can be summarised in the following steps:
-
1. Issuance. The supplier generates the electronic invoice through its ERP or business system connected via API, or directly through the MyInvois Portal.
-
2. HASiL validation. The electronic invoice is transmitted to MyInvois, where HASiL validates whether the document complies with the applicable requirements.
-
3. Notification. Once the validation process has been completed, the supplier and buyer receive the corresponding notifications.
-
4. Delivery to the buyer. The validated electronic invoice is made available or transmitted to the buyer in accordance with the applicable process.
-
5. Rejection or cancellation. Where applicable, the buyer or supplier may carry out the relevant rejection or cancellation process within the conditions and time limits established by HASiL.
-
6. Consultation and management. The parties can consult and manage the corresponding electronic invoice information through the MyInvois ecosystem.
