Malaysia gazetted the Income Tax (Transfer Pricing) (Amendment) Rules 2026 [P.U. (A) 300/2026] on 27 August 2026. The amendments are deemed effective from year of assessment (YA) 2023 and make four targeted changes to the Income Tax (Transfer Pricing) Rules 2023. The most significant is a new domestic offsetting-adjustment mechanism that represents a meaningful development in how transfer pricing disputes can be resolved.

The key changes and their practical implications are summarised below.

1. Rule 13(1A) – New Offsetting Adjustment Mechanism

• Mechanism: Where a Transfer Pricing (TP) adjustment is made to one party under Rule 13(1), the counterparty may apply for a corresponding offsetting adjustment to mitigate double taxation arising from the same controlled transaction, subject to the Director General of Inland Revenue (DGIR)’s approval.

• Conditions: Relief is not automatic and must be requested by the counterparty. The DGIR retains discretionary authority to approve the offsetting adjustment.

• Practical significance: The provision creates a formal mechanism to relieve domestic economic double taxation resulting from TP adjustments between Malaysian related parties.

2. Rule 4(4) – Revised Definition of Multinational Enterprise Group

• Revised definition: A Multinational Enterprise (MNE Group) is now a group of associated enterprises with business establishments in two or more jurisdictions.
• Practical significance: The definition sets out clearly the cross-border requirement for a group to be treated as a MNE Group, which in turn is relevant in determining transfer pricing documentation obligations. Taxpayers that belong to a corporate group with establishments in more than one jurisdiction should review this definition to confirm how their group is classified for documentation purposes going forward.

3. Rule 10(3) – Deletion

• Change: Rule 10(3), which repeated the associated-person test for cost contribution arrangements, is deleted.
• Practical significance: As the definition of controlled transactions is already found in section 140A(5) of the Income Tax Act 1967, this does not change how associated persons are identified for cost contribution arrangements in practice.

4. Rule 3 – Revised Definition of Service

• Change: The wording in the definition of “service” is refined by replacing “facilities provided, or are to be provided” with “facilities, that are, or are to be, provided”.
• Practical significance: This is a refinement of language and does not change what constitutes a service under the principal Rules.

Key takeaways for Taxpayers

The amendments represent a targeted set of refinements to Malaysia's transfer pricing framework. Three of the four changes clarify existing provisions or remove duplicated wording from the Rules.

Given that the amendments take effect from YA 2023, taxpayers currently subject to a transfer pricing audit, review, or dispute covering YA 2023 onward should factor these provisions into their positions, even though the amendments were only gazetted in August 2026. This also extends to historical assessments, where taxpayers may wish to consider whether a prior adjustment against a related party could now support a request for a corresponding offsetting adjustment under Rule 13(1A).
