Transfer Pricing Guidelines 2026: Pricing, Documentation and Disputes

Key steps and distinctions

Analyse actual functions, assets and risks, select an appropriate method and support comparisons with economically comparable independent transactions. Documentation is generally required from YA 2019 where trade revenue exceeds S$10 million or it was required for the previous basis period, subject to the specific transaction exemptions and exit conditions. Prepare it by the return filing due date, provide it within thirty days of IRAS request and retain it at least five years from the transaction basis-period end. A three-year refresh cycle is permitted only while details remain accurate and the simplified-documentation conditions are met. IRAS adjustments from YA 2019 attract a 5% surcharge on the adjustment amount even where no additional tax is payable; documentation offences can separately attract a fine up to S$10,000. The surcharge generally falls due within one month of written notice despite objection or appeal. MAP addresses double taxation under treaties, while an APA agrees pricing criteria in advance. Specific chapters cover services, related-party loans, permanent establishments and cost contributions, so routine service or loan shortcuts should not be applied outside their conditions. The 2026–2028 pilot for baseline marketing and distribution has its own scope. The ninth-edition addition addresses share-based compensation in the pricing guidance.
