Transfer pricing remains a major priority for multinational enterprises (MNEs) operating in the United Kingdom. As corporate tax regulations tighten globally, HMRC has introduced sharper compliance measures focused on documentation, method selection, and risk profiling.

In 2025, UK tax authorities are placing more emphasis on aligning intercompany transactions with the arm’s length principle, particularly for the pricing of goods and services exchanged between related parties across tax jurisdictions.

This blog highlights recent developments in UK transfer pricing regulations, including updated compliance guidance, risk-based audit frameworks, and the expanding role of Advanced Pricing Agreements (APAs) and Mutual Agreement Procedures (MAPs) in preventing disputes.

HMRC’s Updated Transfer Pricing Compliance Guidelines

The updated HMRC document, Help with Common Risks in Transfer Pricing Approaches, identifies typical red flags in controlled transactions and outlines best practices.

Common risk areas:

• Weak documentation
• Lack of comprehensive, contemporaneous documentation increases tax liabilities. Clear support for the price charged in related-party transactions is essential.
• Inappropriate pricing method
• Misapplying transfer pricing methods, such as TNMM or profit split methods, without substantiating their relevance to the goods or services transacted can trigger scrutiny.
• Lack of review
• HMRC urges companies to reassess transfer pricing arrangements regularly to reflect changes in markets, operations, or legal structures.

This guidance is critical for multinational corporations to align their practices with UK tax law and OECD standards.

HMRC’s Risk-Based Approach to Audits

HMRC’s internal manual (INTM485025) provides detailed insight into how tax authorities evaluate risk in related party transactions.

Key points:

• Substance vs. form
• The pricing guidelines for multinationals emphasize the need for transactions to reflect actual economic substance, not just contractual terms.
• Sectoral and jurisdictional profiling
• HMRC uses industry data and country-by-country reports to classify entities by risk level—especially where aggressive pricing or low-tax jurisdictions are involved.
• Early engagement pays off
• Businesses are advised to engage with HMRC proactively when in doubt—especially if the transfer price deviates from the market price.

APA and MAP: Strategic Tools for Risk Mitigation

With increasing cross-border complexity, more MNEs are using dispute resolution mechanisms to gain pricing certainty and reduce audit exposure.

What is an APA?

An Advanced Pricing Agreement (APA) is a binding arrangement between a taxpayer and one or more tax jurisdictions determining the correct pricing method for future intercompany transactions. It ensures that transfer prices remain consistent with the arm’s length principle, reducing uncertainty and risk.

What is a MAP?

A Mutual Agreement Procedure (MAP) is a treaty-based resolution process between two tax authorities aimed at eliminating double taxation caused by adjustments to transfer pricing or corporate tax assessments. MAP ensures equitable treatment when taxing cross-border goods and services.

Key 2025 stats:

• HMRC secured £1.786 billion in transfer pricing-related yield (up from £1.635 billion).
• 27 APAs were concluded, up from 15 the prior year.
• MAP processing times have improved significantly, reflecting enhanced cooperation between tax jurisdictions.

What UK Businesses Should Do Now

1. Review your transfer pricing documentation
2. Ensure it accurately reflects the functions, risks, and assets behind each intercompany transaction.
3. Validate your pricing method
4. Whether you’re using cost-plus, CUP, or profit split methods, ensure the selected approach suits the transaction in question and the economic roles of each party.
5. Proactively assess risk
6. High-risk party transactions—particularly those involving intellectual property, procurement hubs, or goods or services routed through low-tax jurisdictions—deserve closer attention.
7. Use APAs and MAPs
8. For complex structures, APAs offer forward-looking certainty, while MAPs provide a backstop to avoid double taxation on historical adjustments.
