Intercompany transactions between the UK and the USA, as well as the transfer pricing agreement, require careful planning to comply with both jurisdictions’ tax laws. With multinational operations, differences in transfer pricing documentation requirements between the UK and the US, audit risks, and local Transfer Pricing (TP) regulations can expose businesses to penalties or double taxation. 

Using benchmarking software and automated transfer pricing documentation solutions can streamline compliance, ensure arm’s length pricing, and safeguard companies during audits.

This transfer pricing guide explores everything related to the UK-USA transfer pricing agreement, including key structures, benchmarking requirements, compliance standards, and more.

UK to USA Transfer Pricing: A Strategic Compliance Priority

Companies operating between the UK and the USA often engage in varied intercompany transactions, such as product sales, service provision, intellectual property licensing, financing, and shared services, within the transfer pricing agreement space. 

Each transaction must comply with the requirements of the intercompany agreement between the UK and the USA to satisfy regulatory scrutiny. 

Below are key compliance challenges and additional factors that companies must consider, with specific reference to the UK and US contexts.

  • Dual Audits / Joint Audits: Both Majesty’s Revenue and Customs (HMRC) and the Internal Revenue Service (IRS) may examine the same intercompany transactions. The UK participates in “simultaneous controls” or joint examinations under exchange of information treaties and conventions. These audits aim to assess transfer pricing risk across multinational groups and can increase exposure if practices are inconsistent across jurisdictions.
  • Foreign Exchange & Currency Risks: Exchange rate fluctuations can distort whether prices remain at arm’s length over time, especially for long-term contracts. Companies must set policies for revaluation or Foreign Exchange (FX) risk sharing, and ensure documentation reflects how currency risk was considered in setting prices.
  • Penalties & Accuracy-Related Risks: Non-compliant transfer pricing can lead to substantial penalties:
  • In the UK: Penalties for failing to maintain or produce required documentation can reach up to £3,000 for missing records, plus further penalties for late or deficient documentation.
  • In the USA: Penalties of 20% to 40% of the underpayment may apply depending on whether the misstatement is substantial or gross. These are avoidable with adequate contemporaneous documentation and reasonable method choice.
  • Functional / Risk / Economical Substance Analysis: HMRC expects a detailed functional analysis, and high-level templates or generic statements are inadequate. Similarly, the IRS requires that the chosen method align with the functional flows and risk profile of the entities. If one side (UK or US) is low risk but earns high margins, or vice versa, that misalignment becomes a red flag.
  • Ongoing Review and Adjustments / Market Changes: Markets, cost structures, risk allocations, interest rates, and regulations evolve. What was arm’s length under one set of conditions may not be under another. Both UK and US authorities expect that transfer pricing arrangements be kept up to date and that documentation show periodic testing or adjustment. 

Common UK–USA Intercompany Structures and TP Methods

Understanding typical intercompany setups is critical for selecting the correct transfer pricing method. Common structures include:

Intercompany StructureTypical TP MethodDescriptionKey Audit Risks
Captive R&D CentersCost Plus Markup Transfer Pricing ModelUK subsidiaries often perform R&D on behalf of a U.S. parent and are compensated with a markup on total costs incurred. – Insufficient evidence for markup level
– Difficulty proving economic contribution
– Misclassification of routine vs. non-routine intangibles
Local DistributorsResale Price Method (RPM)A UK distributor purchases goods from the U.S. parent and resells them locally. TP is based on gross margins comparables from independent distributors. – Distributor margin not aligned with market benchmarks
– Lack of comparable data
– Functional mischaracterization as a limited-risk entity
Back-Office Support / Shared ServicesCost Plus / Transactional Net Margin Method (TNMM)Shared services like HR, IT, or finance are charged to group companies based on cost allocation plus an arm’s-length markup.– Inadequate allocation of shared costs
– Missing intercompany agreements
– Overcharging for routine services
Intellectual Property (IP) LicensingComparable Uncontrolled Price (CUP) / Profit SplitU.S. entities license IP to UK subsidiaries, which pay royalties. CUP is used if comparable royalty rates exist; profit split is used for highly integrated IP.– Incorrect or non-arm’s length royalty rates
– Outdated or missing license agreements
– Misallocation of intangible-related profits
Contract Manufacturing ArrangementsCost Plus or TNMMUK entities act as limited-risk manufacturers for U.S. parent companies, producing goods exclusively for group entities.– Misallocation of production risks- Inappropriate cost base-
Lack of functional analysis support
Commissionaire or Sales Agent StructuresTNMM / Commission-Based PricingA UK entity acts as an agent selling U.S. products, earning a commission instead of owning inventory.-Mischaracterization as a distributor
– Inadequate documentation of commission rates
– PE risk due to dependent agent status

By combining transfer pricing benchmarking software and audit-ready templates, companies can align pricing with both HMRC and IRS expectations.

Benchmarking Requirements Under UK Transfer Pricing Law

The UK follows the Organization for Economic Cooperation and Development (OECD) aligned rules for transfer pricing documentation. Key points include:

  • Master File / Local File Scope: UK entities within groups that meet the Country-by-Country Reporting Regime (i.e., global consolidated revenues ≥ €750 million) are required to maintain a Master File and Local File in a prescribed format.
  • Materiality / De Minimis Rules: HMRC allows a £1 million de minimis threshold per category of controlled transactions for exclusion from the Local File, except for certain inherently risky categories (e.g., intangibles, profit splits, cost contribution arrangements).
  • Benchmarking Methods Accepted: The UK accepts the standard set of OECD methods, CUP, Resale Price / Resale Minus, Cost Plus, Profit Split, and TNMM, and allows use of alternative methods if justified.
  • Comparables / Data Sources: While not statutorily prescribed, companies commonly use commercial databases (e.g., Orbis, Amadeus) and public comparable financial data to support benchmarking analyses, consistent with OECD guidelines.
  • Documentation Timing/Provision: Documentation must exist at the time of tax return filing (i.e., contemporaneously). It need not be filed with the return, but must be provided to HMRC on request (generally within 30 days). Failure to do so can attract penalties (e.g, up to £3,000).

Commenda’s UK-specific TP engine simplifies benchmarking and documentation, generating compliant Master and Local Files efficiently.

USA Transfer Pricing Rules and Documentation Standards

The USA enforces stringent TP regulations under Internal Revenue Code (IRC) Section 482, emphasizing:

  • The IRS may allocate income, deductions, credits, or allowances among related entities to ensure arm’s-length treatment and prevent tax evasion. 
  • Taxpayers are required to maintain “contemporaneous documentation,” i.e., documentation existing at the time the tax return is filed (or reasonably expected to be filed).
  • If the IRS requests it during examination, the documentation must generally be provided within 30 days.

Reporting Forms Required

Here are the forms required by the USA:

  • Form 5471: Required for U.S. persons with certain interests in foreign corporations. Failure to file a return in a timely manner can incur a $10,000 penalty per return, with additional continuing penalties if not remedied within the specified time.
  • Form 5472: U.S. corporations that are at least 25% foreign-owned (or foreign corporations with a U.S. branch) must file this form for reportable intercompany transactions.
    • The penalty for failing to file Form 5472 is $25,000 for each such failure.
    • If noncompliance continues beyond 90 days after IRS notification, additional $25,000 penalties apply for each 30-day period (or part thereof).

Automated solutions, such as Commenda, help prepare IRS-aligned reports and generate intercompany agreements with jurisdiction-specific clauses, reducing audit exposure.

Why Most UK–USA TP Agreements Fail Audits

Despite best efforts, many intercompany agreements fail due to:

  • Template Reuse: Using generic agreements that do not reflect actual transactions.
  • Missing Clauses: Intellectual property, withholding tax, or local law requirements omitted.
  • Outdated Markups: Cost plus percentages or royalty rates not updated for inflation or market conditions.

Commenda addresses these gaps by offering prebuilt, editable templates aligned with both UK and USA regulations, ensuring agreements are audit-ready.
