Why contracts, valuation and accounting entries do not complete a cross-border restructuring unless decision-making, conduct and evidence move with them.

In the previous instalment, the illustrative group had identified what was being transferred and considered its value on the transfer date, including customer renewals, forecasts and possible variable consideration.

The valuation was now substantially complete. The implementation documents gave the transfer an effective date and the finance team was ready to record the agreed consideration.

That did not end the tax analysis.

The next question was more basic and, in practice, sometimes more difficult:

Had the business actually changed in the way the restructuring documents described?

This is not simply a documentation point. Transfer pricing begins with the actual transaction between the associated enterprises. Contracts are important, but must be tested against functions, assets, risks and conduct.

A group cannot establish that risk has moved merely by changing the wording of an agreement. Nor can the selected pricing method prove the underlying functional profile. A cost-plus return does not, by itself, make an entity routine; the functions and decision-making must support that conclusion.

For CFOs, tax directors and business owners, the practical task is therefore to connect the legal step plan to operational reality.

The signed agreement was only the starting point

Assume that the illustrative group transfers a portfolio of customer contracts from its UK company to an overseas principal with effect from 1 January. The agreement allocates future customer risk and residual profit potential to the principal. A valuation supports the transfer price and an intercompany invoice is raised.

On paper, the transaction appears complete.

But the UK commercial director continues to approve non-standard pricing. UK personnel decide which customers receive extended payment terms. Product-development priorities are still set following meetings led from the UK. Significant renewals require the same UK approval as before, and customers continue to treat the UK team as the effective commercial counterparty.

Those facts do not necessarily mean that nothing was transferred. Rights may have moved and some activities may properly remain under a UK service arrangement. They do require the group to delineate what actually occurred.

The analysis should identify, with specificity, the economically significant decisions relevant to the transferred business. Depending on the model, these may include decisions to accept or decline customer opportunities, set or depart from pricing parameters, grant credit, incur development expenditure, manage service failure, protect commercially valuable know-how or terminate an unprofitable relationship.

The important evidence is who had the capability and authority to decide, who actually decided and which enterprise could financially bear the exposure.

A transfer can have more than one operational date

Implementation is rarely instantaneous.

The legal assignment of contracts may occur on 1 January, customer notices on 15 January, billing migration on 1 February and the transfer of approval authority on 15 March. Systems access, insurance arrangements and responsibility for complaints may move on still different dates.

The earliest date may overstate what changed; the final date may ignore rights and activities already moved. The task is to understand the transition.

Suppose a significant renewal was negotiated and approved in the UK in February, while the new overseas decision framework did not become operational until March. It would be difficult to support the proposition that all relevant commercial control had passed to the principal on 1 January merely because that was the date in the restructuring agreement.

The transition may require segmentation of transactions or a temporary reward for continuing UK functions. The answer depends on the facts, materiality and method, not an arbitrary monthly apportionment.

The transfer price and the future operating return answer different questions

The arm’s-length compensation for the restructuring addresses what was transferred or surrendered at the point of change. The return earned after the restructuring remunerates the functions performed, assets used and risks assumed under the new model.

If the UK company transfers valuable contractual rights and is paid for them, that does not eliminate the need to remunerate material services it continues to provide. Conversely, paying a service fee after the restructuring does not demonstrate that the original transfer price was correct.

The finance team should therefore be able to reconcile at least three items:

• the consideration for the transferred rights, assets or business activity;
• the post-restructuring remuneration for continuing UK functions; and
• any transition-period adjustment for activities that moved later than planned.

The reconciliation should match the accounts, invoices and tax computations. A sound policy can still fail through incorrect counterparties, currencies, cost bases or dates.

A UK subsidiary and a UK permanent establishment remain separate analyses

The illustrative group must then identify whose conduct is being examined.

The remuneration of the UK company concerns transactions between separate enterprises and is tested under the transfer pricing rules. The attribution of profit to a UK permanent establishment concerns different parts of the same foreign enterprise. Transfer pricing techniques are used in both exercises, but the legal frameworks are not interchangeable.

An arm’s-length service fee paid to the subsidiary does not necessarily measure the whole profit attributable to a foreign principal’s UK permanent establishment. Equally, an internal allocation within the foreign enterprise is not a legally binding contract between two companies.

For UK periods beginning on or after 1 January 2026, the revised statutory framework expressly links PE attribution more closely to the OECD materials, including the authorised approach to functions, assets and risks. That reinforces the need for a factual implementation record; it does not convert the subsidiary and PE calculations into one exercise.

Corporate residence is another question, not a substitute answer

If senior UK personnel continue to make strategic decisions for the overseas principal, the group should also consider whether the facts affect the company’s residence position.

That review is not resolved by the transfer-pricing conclusion. Corporate residence, permanent-establishment exposure and profit attribution ask different legal questions. The same board papers, approval trails and executive conduct may be relevant to more than one of them, but the conclusions must be reached separately and then coordinated.

Moving operational authority does not automatically make the principal UK resident, while formal overseas board meetings are not conclusive. The level of UK decision-making matters.

Inconsistent implementation can recreate double taxation

The earlier articles in this series considered double-tax relief and the Mutual Agreement Procedure. Implementation risk can bring those issues back.

If the UK analyses the conduct as showing that important functions remained here, while the other jurisdiction treats the contractual transfer as fully effective from day one, the same profit may be taxed twice. A MAP may be available under the relevant treaty where taxation is not in accordance with its terms, but it is better to reduce the factual disagreement before returns are filed.

The group should use a common factual record across jurisdictions: the same chronology, decision map, data and explanation of transitional departures. Legal consequences may differ, but the history should not.

The board needed an implementation file, not another policy paper

For the illustrative group, the proportionate solution would be a short implementation file maintained from the effective date. It would record:

• what legal rights and obligations moved;
• when operational authority, systems and customer-facing responsibility changed;
• who made the first significant decisions under the new model;
• how transition-period transactions were treated;
• whether invoices and accounting entries followed the agreed terms; and
• which evidence supports the position in each relevant jurisdiction.

Tax, Finance and business leaders should own this jointly: Tax cannot verify a restructuring from contracts alone.

Contemporaneous evidence is also more reliable than a year-end reconstruction. Approval records, customer communications, system permissions and functional interviews are easier to capture while the change is taking place and before key personnel move roles.

The group had therefore advanced to the next practical question:

Can it prove when each economically significant function actually moved — and explain any period in which the business did not yet operate as the agreement intended?

That is the point at which a priced restructuring becomes an implemented operating model.
