Why identifying UK significant people functions does not, by itself, determine the CFC charge

In my previous article, I considered an international group whose transfer pricing review raised a more fundamental controlled foreign company question.

The overseas principal legally owned the group’s intellectual property, contractually assumed its principal commercial risks and retained the residual profit. The UK company employed much of the management and operational workforce and received a cost-plus return.

The documents supported the structure.

The contemporaneous evidence did not.

Emails, investment papers and management records suggested that commercially significant decisions had been formulated and effectively taken in the United Kingdom before being formally approved overseas.

The review therefore identified a potential Chapter 4 CFC issue.

That was not, however, the end of the analysis.

It was the beginning of the more difficult part.

The group now had to determine how much profit, if any, remained within the CFC charge gateway after applying the transfer pricing rules, the statutory filters, the Chapter 4 attribution process and the available exemptions and exclusions.

The first question from the finance director was understandable:

If the UK company’s transfer pricing return is increased, will the group then suffer a CFC charge on the same profit?

The answer was that the two regimes must be considered together, but in the correct order.

A finding that UK personnel performed significant people functions does not automatically bring all of the foreign company’s profits into the United Kingdom. Nor should the CFC computation simply be added mechanically to a transfer pricing adjustment.

The group needed a profit bridge, not two independent tax calculations.

A significant people function is not itself a tax charge

The identification of a UK significant people function is a factual conclusion.

It tells the group that a person in the United Kingdom may have performed an active decision-making function relevant to the assumption or management of a risk, or to the economic ownership and management of an asset.

It does not, by itself, determine the amount of any Chapter 4 profit.

Before a CFC charge can arise, the group must still consider whether an entity-level exemption applies, whether Chapter 4 is engaged through the Chapter 3 gateway, which assets and risks are relevant, which significant people functions relate to those assets and risks, where those functions were performed and how much profit is attributable to them.

HMRC’s guidance is explicit that transfer pricing is the primary remedy for an inappropriate division of profit between companies within a group. Chapter 4 is intended to address cases in which transfer pricing is not an available or appropriate remedy for the separation of assets and risks from the activities that support them.

This distinction is important.

A transfer pricing review asks what arm’s length provision would have been made between the UK company and the overseas company.

The Chapter 4 analysis asks a different question: to what extent do profits remaining in the foreign company arise from assets and risks that would be attributed to a notional UK permanent establishment because the relevant significant people functions were performed in the United Kingdom?

The analysis overlaps factually, but the statutory questions are not identical.

The first calculation remained the transfer pricing calculation

The group therefore returned to the controlled transactions.

It did not begin by taking the overseas company’s profit and applying a broad percentage representing the involvement of UK management. That would have been commercially convenient but technically unreliable.

Instead, it reconsidered the actual relationship between the companies.

The review examined:

• the functions the UK company had actually performed;
• the assets it had used;
• the risks it had contractually assumed;
• the risks it had, in practice, controlled;
• the personnel who possessed the capability and authority to make the relevant decisions;
• the financial capacity of the overseas company to assume those risks; and
• whether the conduct of the parties was consistent with the contractual arrangements.

The fact that the UK company had historically been rewarded on a cost-plus basis did not establish that it was a routine service provider.

Cost-plus is a pricing method. It is not a factual characterisation.

If the UK personnel merely gathered information, performed technical work and implemented decisions genuinely made by the overseas principal, a cost-based return might remain appropriate.

If, however, those individuals selected the projects, determined the investment parameters, approved the assumption of risk, decided whether development should continue and controlled the response when the risk materialised, their activities might be inconsistent with the characterisation of the UK company as a routine service provider.

In that case, the appropriate transfer pricing response might involve a higher service return, a return linked to the relevant intangible contribution, a profit-split methodology or a wider reconsideration of the accurately delineated transaction.

The correct result could not be obtained simply by selecting a higher mark-up from a benchmarking database.

The transfer pricing adjustment did not necessarily close the CFC question

Assume, for illustration, that the overseas principal initially reported trading profits of £18 million.

Following the functional and factual analysis, the group concludes that the UK company should have received an additional £4 million under the arm’s length principle.

Subject to the detailed computational treatment, this may increase the UK company’s taxable profits and reduce the arm’s length measure of the profit properly attributable to the overseas company.

It would not follow that the remaining £14 million was automatically outside Chapter 4.

The group would still need to ask why the overseas company was entitled to retain that remaining profit.

Some of it might arise from genuine activities performed outside the United Kingdom: local market development, foreign manufacturing capabilities, non-UK management, capital deployed at risk, foreign customer relationships or intellectual property that was genuinely developed and controlled overseas.

Some of it might arise from assets and risks legally allocated to the overseas company but managed through UK significant people functions.

The CFC analysis concerns the second category.

The exercise is therefore not:

Foreign profit × percentage of UK management involvement.

It is:

What profit would the CFC have earned if it had not held the assets or borne the risks attributable to the relevant UK significant people functions?

That requires the group to trace the profit to the particular assets, risks and decision-making functions that generated it.

Chapter 4 is an attribution exercise

HMRC’s Chapter 4 guidance sets out eight statutory steps.

Broadly, the analysis identifies the relevant assets and risks, excludes negligible items, identifies the relevant significant people functions, determines which of those functions are performed in the United Kingdom and attributes assets and risks to a notional UK permanent establishment.

It then excludes assets and risks where the attribution is not mainly to the United Kingdom, calculates provisional Chapter 4 profits and applies the further statutory exclusions.

This structure prevents the analysis from becoming an undifferentiated substance test.

A group does not fail Chapter 4 merely because senior UK executives communicate regularly with the directors of a foreign subsidiary.

Equally, it does not pass merely because the foreign company has offices, employees and locally resident directors.

The question is asset-specific and risk-specific.

A foreign company may exercise genuine control over one category of risk but rely materially on UK decision-makers for another.

Its local directors may make independent decisions concerning customer credit and regional marketing while the UK management team controls the development and exploitation of the group’s core technology.

In that case, the profit analysis may need to distinguish between those different assets and risks rather than treating the company as either wholly substantive or wholly artificial.

The group had one principal but several profit streams

This was the point at which the group’s original transfer pricing model became difficult to defend.

The model treated the overseas company as a single entrepreneurial principal receiving a single residual profit.

The factual review showed that the residual profit came from several economically different sources.

One part arose from the exploitation of established intellectual property.

Another arose from the development of new products.

A further part related to commercial strategy and the assumption of market risk.

Other profits reflected procurement efficiencies, manufacturing coordination, local sales activity and foreign market relationships.

The location of decision-making was not the same for each profit stream.

The overseas board had exercised genuine authority over certain licensing and regional commercial decisions. It had received information before those decisions were taken, possessed the necessary experience and could demonstrate that it had rejected or modified proposals.

The position concerning new intellectual property development was different.

The UK team had identified the projects, prepared the investment cases, determined the budget, selected the technology, assessed whether development should continue and controlled the response when projects failed to meet their milestones.

The overseas board had approved the expenditure, but only after the commercially decisive work had been completed.

The issue was therefore not whether the overseas company had any substance.

It was whether it had performed the functions necessary to justify the particular profits allocated to it.

Formal authority and practical authority had diverged

The legal documents gave the overseas company authority to approve investment and manage the relevant risks.

The operating model gave the UK management team the information, expertise and practical ability to determine what would happen.

That divergence mattered.

A company cannot demonstrate control over risk merely by showing that its directors had the legal right to approve a proposal. It must be able to demonstrate that the relevant decision-makers had access to the information required to evaluate the risk, understood the available alternatives, had the competence and authority to decide between them and remained responsible for managing the consequences.

The timing of the evidence was particularly important.

An overseas board may receive a detailed paper explaining why a particular product should be launched. The minutes may record that the directors considered the commercial risks and approved the proposal.

However, if the UK management team had already committed development expenditure, instructed employees, negotiated with suppliers and communicated the launch timetable before the meeting occurred, the board’s approval may have been confirmatory rather than determinative.

The question is not simply who said “yes”.

It is who controlled the process that made “yes” the only realistic answer.

Historical remediation and future remediation were different exercises

Once the weakness had been identified, the group considered transferring greater decision-making responsibility to the overseas company.

That could improve the future position.

It could not rewrite the past.

For historical periods, the analysis had to follow what the individuals actually did during each relevant accounting period.

New delegations of authority, revised intercompany agreements and more detailed board papers could not establish that the overseas company controlled risks in a period when the contemporaneous evidence showed otherwise.

For future periods, the group had two commercially realistic choices.

The first was to establish a genuine foreign principal.

That required more than relocating board meetings. The overseas company needed decision-makers with appropriate competence, information and authority. They needed to become involved before proposals were effectively settled and to remain responsible for managing the resulting assets and risks.

The second choice was to retain the existing operating model but allocate profit in a manner consistent with the functions actually performed in the United Kingdom.

The group ultimately concluded that attempting to preserve a foreign-principal return without transferring genuine control would create recurring transfer pricing and CFC exposure.

It therefore redesigned both the operating model and the profit allocation.

Exemptions and exclusions still had to be tested

Even where the factual review identifies UK significant people functions, a CFC charge does not necessarily arise.

The UK CFC regime contains five entity-level exemptions: the exempt period exemption, excluded territories exemption, low profits exemption, low profit margin exemption and tax exemption. If one of these applies for the relevant accounting period, the CFC’s profits are exempt from the CFC charge for that period.

The tax exemption, for example, broadly applies where the CFC’s local tax amount is at least 75% of the corresponding UK tax, subject to the detailed statutory assumptions and adjustments.

Where no entity-level exemption applies, the Chapter 3 filters and Chapter 4 exclusions must still be considered.

The Chapter 4 trading profits exclusion contains a series of conditions relating to matters including business premises, income, management expenditure, intellectual property and exports of goods. These conditions may provide a more mechanical route out of Chapter 4, but all applicable conditions must be satisfied and anti-avoidance provisions must also be considered.

The management expenditure condition can be especially relevant because it examines the expenditure associated with individuals who manage or control the assets and risks giving rise to the CFC’s profits. HMRC’s guidance states that the condition is generally met unless UK-related management expenditure exceeds 20% of the total related management expenditure, with a separate asset-by-asset or risk-by-risk alternative in certain circumstances.

These tests should not be treated as a substitute for understanding the facts.

A group may satisfy a numerical condition for one period and fail it in another because a senior employee moved, a new product development programme commenced or decision-making responsibilities changed.

The CFC analysis must therefore be performed by reference to the relevant accounting period, rather than assuming that a conclusion reached when the structure was established remains valid indefinitely.

Foreign tax must also be included in the model

The gross amount of profit passing through the CFC charge gateway is not necessarily the amount on which the group ultimately bears additional UK tax.

The calculation must take account of the UK company’s relevant interest in the CFC and the creditable tax attributable to the chargeable profits.

Creditable tax can include qualifying foreign tax paid by the CFC, certain UK taxes and, in appropriate circumstances, a comparable foreign CFC charge imposed by another jurisdiction. The detailed credit calculation is subject to the normal double taxation relief principles and statutory limitations.

This is another reason why the transfer pricing and CFC workstreams should not be modelled independently.

The group needs a single reconciliation showing:

1. the profits originally reported by the UK and overseas companies;
2. the transfer pricing adjustments required under the arm’s length principle;
3. the overseas company’s assumed total profits under the UK CFC assumptions;
4. the assets and risks examined under Chapter 4;
5. the provisional profits attributable to UK significant people functions;
6. the effect of the Chapter 4 exclusions and any entity-level exemption;
7. the apportionment to the relevant UK chargeable companies; and
8. the creditable tax available against the resulting CFC charge.

Without that bridge, there is a real risk that the group will compare figures prepared on different conceptual and computational bases.

The TP&PDCF decision came after the analysis, not before it

The group also considered whether the Transfer Pricing and Profit Diversion Compliance Facility was an appropriate route for resolving the historic position.

HMRC’s expanded facility is intended to cover a broader range of material non-financial transfer pricing risks, not only arrangements traditionally associated with diverted profits tax.

HMRC expects a disclosure to be based on a detailed factual and technical review and supported by evidence. The published annexes contemplate an evidence log, a UK profit and loss account analysed by transfer pricing policy, staff profiles and revenue-and-cost information for relevant overseas entities.

The group did not register merely because it had identified a difficult question.

HMRC’s guidance states that a multinational which is confident that its transfer pricing is correct and that it is paying the correct amount of UK Corporation Tax should not use the facility.

The appropriate sequence was therefore:

• establish the facts;
• determine the transfer pricing position;
• perform the CFC gateway and exemption analysis;
• quantify the potential liabilities, interest and penalties;
• assess the quality of the available evidence; and
• only then decide whether the facility offered the most appropriate route to resolution.

Registration without a sufficiently developed analysis would merely accelerate the point at which the group needed to explain a position it had not yet resolved internally.

The ICTS will make inconsistent positions easier to identify

The International Controlled Transactions Schedule will add a further practical dimension.

The government intends that the ICTS reporting obligation will apply to accounting periods beginning on or after 1 January 2027. It is designed to give HMRC structured information concerning cross-border related-party transactions and foreign permanent-establishment dealings, enabling automated and data-led transfer pricing risk assessment.

The technical consultation closed on 31 July 2026 and HMRC is now analysing the responses.

The ICTS is not a CFC return.

Nevertheless, it will help HMRC identify the overseas entities receiving UK-connected profit streams, the nature and value of those transactions and the transfer pricing methods applied.

HMRC may then compare that information with staff locations, corporate tax returns, country-by-country reporting, statutory accounts, group structures and the evidence obtained during a compliance review.

A group reporting substantial payments to an overseas IP owner may therefore need to explain not only how the royalty or service charge was calculated, but why the overseas entity was entitled to the underlying intangible return.

The transfer pricing method and the CFC analysis must tell a consistent commercial story.

What happened after the second review

The group divided its response into three periods.

For historic accounting periods, it reconstructed the actual decision-making process and quantified the transfer pricing and CFC consequences on the basis of the contemporaneous evidence.

For the current accounting period, it identified the date on which responsibilities genuinely began to change. It did not assume that a revised agreement signed during the year applied retrospectively to decisions already taken.

For future periods, it redesigned the governance and pricing model.

Certain decisions remained in the United Kingdom and the UK profit allocation was increased accordingly.

Other decisions were transferred to suitably qualified individuals employed or engaged by the overseas company. Those individuals were given the information, resources and authority required to evaluate proposals before implementation began. The overseas company’s remuneration was then aligned with the assets and risks it genuinely controlled.

The group also introduced a contemporaneous decision register recording:

• the commercial decision under consideration;
• the asset or risk affected;
• the individuals who prepared the proposal;
• the individuals authorised to decide;
• the information supplied to decision under consideration;
• the asset or risk affected;
• the individuals who prepared the proposal;
• the individuals authorised them;
• the alternatives considered;
• the decision taken;
• the date on which implementation was authorised; and
• responsibility for monitoring the outcome.

The objective was not to manufacture a tax file.

It was to ensure that the operating model, governance process, transfer pricing policy and tax analysis described the same business.

The question groups should ask after finding a UK significant people function

Finding a UK significant people function is important, but it is not the conclusion.

The next questions are more precise:

What asset or risk does the function relate to?

What profit does that asset or risk generate?

Has the UK company already received an arm’s length reward for its contribution?

What profit remains in the overseas company after the transfer pricing analysis?

Would that profit have arisen if the overseas company had not held the asset or borne the risk?

To what extent would the asset or risk be attributed to UK significant people functions under the Chapter 4 steps?

Do the Chapter 3 filters, Chapter 4 exclusions or entity-level exemptions apply?

What foreign tax is creditable against any resulting CFC charge?

And, perhaps most importantly, does the contemporaneous evidence support the answer?

The transfer pricing review may identify the CFC question.

Only a properly sequenced profit attribution analysis can answer it.
