Transfer pricing refers to the prices set for transactions between affiliated companies inside the same multinational enterprise (MNE) — for example, when a subsidiary in Ireland licenses intellectual property to a sister company in Germany, or when a Singapore-based hub sells components to a manufacturing arm in Mexico. Because these are intra-group transfers rather than open-market deals, the price can be manipulated to shift taxable profits from high-tax to low-tax jurisdictions.
To constrain this, tax authorities apply the arm's length principle: related-party transactions must be priced as if the parties were unrelated and dealing at market terms. This standard is codified in Article 9 of the OECD Model Tax Convention and in the UN Model Tax Convention, and is elaborated in the OECD Transfer Pricing Guidelines for Multinational Enterprises and Tax Administrations (most recently consolidated in 2022). Acceptable methods include the comparable uncontrolled price (CUP), resale price, cost-plus, transactional net margin (TNMM), and profit split methods.
Transfer pricing became a central issue in the OECD/G20 Base Erosion and Profit Shifting (BEPS) project launched in 2013. BEPS Actions 8–10 tightened rules on intangibles, risk, and capital, while Action 13 introduced country-by-country reporting (CbCR) for MNEs with consolidated revenue above €750 million. The subsequent Two-Pillar Solution agreed by the OECD/G20 Inclusive Framework in October 2021 — Pillar One reallocating taxing rights and Pillar Two establishing a 15% global minimum effective tax rate — was designed in part to reduce incentives for aggressive transfer pricing.
High-profile disputes illustrate the stakes. The European Commission's 2016 state-aid decision ordered Ireland to recover roughly €13 billion from Apple over rulings on intra-group profit allocation; the Court of Justice of the EU upheld that decision in September 2024. Other notable cases involve Amazon, Starbucks, Fiat, and the long-running Glencore and Chevron litigation in Australia.
Example
In September 2024, the Court of Justice of the EU upheld the European Commission's finding that Ireland's transfer pricing rulings for Apple constituted unlawful state aid, requiring recovery of around €13 billion in back taxes.
Frequently asked questions
Mispriced intra-group transactions allow MNEs to shift profits to low-tax jurisdictions, eroding the tax base of countries where real economic activity occurs. The OECD estimates BEPS practices cost governments USD 100–240 billion annually.
