Regulatory updates - Malaysia

On September 25, 2026, the Inland Revenue Board of Malaysia (IRBM) announced updates to the MyInvois Software Development Kit (SDK) covering API and validation documentation. The changes are intended to improve document search and retrieval functionality and help developers identify and resolve validation errors.

API documentation updates

The Search Documents API now includes an optional classification code filter. An optional version number parameter has also been added for responses returned through the Get Document and Get Document Details APIs.

Validator documentation updates

IRBM has introduced dedicated error reference pages for the Structure, Core Fields, Signature, Taxpayer, Referenced Documents, Code, Duplicate Document, and Currency validators. These pages provide common error codes, possible causes, and recommended resolutions.

The standard error response documentation has also been updated with direct links to the relevant SDK error reference pages, helping taxpayers and service providers troubleshoot validation issues more efficiently.

These changes will be implemented in the Production environment on October 24, 2026.

On September 7, 2026, the Inland Revenue Board of Malaysia (IRBM) published e‑Invoice Specific Guideline Version 4.9. The update introduces a concession for individual buyers intended to simplify the e‑Invoice issuance process and reduce the burden of providing taxpayer identification information.

Under the revised guidance, suppliers may accept more flexible identification information when issuing e‑invoices to individuals.

For Malaysian individuals holding a MyKad or MyTentera, and non‑Malaysian residents holding a MyPR or MyKAS, the individual may provide:

• A Tax Identification Number (TIN); or
• A MyKad, MyTentera, MyPR, or MyKAS identification number; or
• Both the TIN and the relevant identification number.

For non‑Malaysian individuals who do not hold MyPR or MyKAS, the individual may provide:

• A TIN; or
• Both a TIN and a passport number.

IRBM has clarified that the TIN referred to for non‑Malaysian individuals is a TIN assigned by IRBM. Where a non‑Malaysian individual does not have a TIN, suppliers may use the general TIN specified in Appendix 1 of the e‑Invoice Specific Guideline, together with the individual's passport number.

On August 30, 2026, the Inland Revenue Board of Malaysia (IRBM) published e-invoice Guideline version 4.8, increasing the annual turnover or revenue threshold for exemption from e-invoice requirements from MYR 1 million (ca. EUR 215,000) to MYR 3 million (ca. EUR 640,000) and providing additional clarification on the scope of the exemption.

Exemption criteria

The exemption for taxpayers with annual turnover or revenue below MYR 3 million applies to all categories of taxpayers, including individuals, partnerships, companies and co-operatives.

However, IRBM clarified that eligibility is not determined solely by the taxpayer's own turnover or revenue. The exemption does not apply where:

• the taxpayer has one or more non-individual shareholders (or equivalent) with annual turnover or revenue of at least MYR 3 million;
• the taxpayer is a subsidiary of a holding company with annual turnover or revenue of at least MYR 3 million; or
• the taxpayer has a related company or joint venture with annual turnover or revenue of at least MYR 3 million. For this purpose, a related company is one that controls or is controlled by another company, is under common control with another company, or where one company holds 20% or more of the shares in the other company.

Newly established businesses

For businesses or operations commencing between 2023 and 2025 with annual turnover or revenue of at least MYR 3 million, the e-invoice implementation date remains July 1, 2026.

For businesses or operations commencing from 2026 onwards, the e-invoice implementation date is July 1, 2026, or the date operations commence, as applicable. However, where first-year turnover or revenue is expected to be below MYR 3 million, the implementation date is deferred until January 1 of the second year following the year in which annual turnover or revenue reaches MYR 3 million.

Other taxpayers

The guideline also reiterates that statutory bodies, statutory authorities, local authorities and international organisations are required to implement e-invoicing from July 1, 2025, in relation to transactions involving goods sold or services performed.

The updated guidance may require businesses with annual turnover or revenue between MYR 1 million and MYR 3 million to reassess their obligations, particularly where they have already commenced e-invoice issuance under the previous threshold. Ownership structures and relationships with holding companies, related companies and joint ventures should also be reviewed when determining eligibility for the exemption.
