Transfer Pricing: A Complete UK Guide

UK transfer pricing rules ensure that transactions between connected parties are priced at arm's length, meaning the price would be the same if the parties were independent of each other. The rules apply to both domestic and cross-border transactions and affect companies, partnerships, and individuals carrying on a trade or profession.

The Arm's Length Principle

The arm's length principle is the foundation of transfer pricing. It requires that the consideration for any transaction between connected persons be equivalent to what would have been agreed between independent parties dealing at arm's length. HMRC follows the OECD Transfer Pricing Guidelines, which provide detailed guidance on applying the principle to various types of transactions, including goods, services, intellectual property, and financing arrangements.

The UK rules are found in Part 4 of the Taxation (International and Other Provisions) Act 2010 (TIOPA 2010). They apply to transactions between any connected persons, which includes companies under common control, companies and their shareholders, and individuals and companies they control.

Documentation Requirements

While the UK does not have a statutory requirement to maintain transfer pricing documentation, in practice you must be able to demonstrate that your pricing is arm's length. HMRC can request documentation during an enquiry, and failure to provide adequate evidence can result in adjustments and penalties.

Best practice is to maintain a transfer pricing master file and local file following the OECD's three-tiered approach. The master file provides an overview of the global business, while the local file covers specific transactions with UK connected parties. A country-by-country report is required for multinational groups with annual group revenue exceeding €750 million.

SME Exemptions

Small and medium-sized enterprises (SMEs) benefit from significant exemptions. A small enterprise (fewer than 50 employees and turnover or assets under €10 million) is exempt from transfer pricing rules unless HMRC directs otherwise. Medium-sized enterprises (fewer than 250 employees and turnover under €50 million or assets under €43 million) are also exempt but must comply with basic record-keeping requirements.

The SME exemption does not apply to transactions where the other party is in a non-qualifying territory (generally a territory that is not within the EEA or does not have a DTA with the UK). It also does not apply to transactions involving partnerships where any partner is not an SME.

Compensating Adjustments

If HMRC makes a transfer pricing adjustment increasing the profits of a UK company, a compensating adjustment may be available to the other party to the transaction. This prevents double taxation of the same economic profit. The compensating adjustment is made by reducing the profits of the other connected party by the same amount.

Compensating adjustments must be claimed within two years of the end of the accounting period to which they relate. They are available only where the other party is within the charge to UK tax and the adjustment is just and reasonable.

Advance Pricing Agreements

For complex transfer pricing arrangements, HMRC offers advance pricing agreements (APAs). An APA is a binding agreement between HMRC and a taxpayer that sets out the transfer pricing methodology for specified transactions for a defined period, typically three to five years. APAs provide certainty and reduce the risk of future disputes.

The APA process involves submitting a detailed application, including a functional analysis of the relevant entities, a description of the proposed methodology, and supporting economic evidence. HMRC's APA team reviews the application and may negotiate with the taxpayer before reaching agreement. The cost of an APA depends on the complexity of the case but can range from £25,000 to over £100,000.

Penalty Regime

Transfer pricing penalties apply where a return is submitted that does not reflect arm's length pricing and the resulting tax shortfall is attributable to careless or deliberate behaviour. The penalty regime follows the standard HMRC penalty framework: up to 30% for careless inaccuracies, up to 70% for deliberate but not concealed inaccuracies, and up to 100% for deliberate and concealed inaccuracies. Prompted and unprompted disclosure can reduce these percentages.

Where an APA is in place and the taxpayer follows its terms, no penalties can arise for the covered transactions. This is one of the key benefits of obtaining an APA.
