Why a disappointing result after a cross-border restructuring calls for an explanation before an intercompany invoice.

3 November 2026

The previous instalment followed an illustrative international group through the implementation of its restructuring. The task was to establish when contractual rights, operational authority and decision-making actually moved.

Assume that work has now been completed. The UK company provides continuing commercial support to an overseas principal under the new arrangements. Finance can identify the transition period and reconcile the opening entries.

Then the first results arrive.

The UK company is below its expected return. The principal has also missed its forecast. The CFO asks whether Finance should raise an additional service invoice to restore the UK company’s margin.

The spreadsheet can calculate an amount immediately. The harder question is whether that amount represents an arm’s-length payment for the transactions that actually occurred.

A variance is a starting point

A disappointing result can have several causes: an omitted recharge, lower customer demand, unexpected transition costs, inefficient delivery or a change in the work performed. Those explanations do not necessarily lead to the same tax treatment.

For this illustrative group, the sensible first step is a reconciliation from the expected operating result to the actual result, identifying each material cause and the period concerned. It should connect the management accounts to the relevant legal entity and transactions.

That exercise also exposes a common weakness in reporting. A group dashboard may combine legacy customer income, the new service activity and a one-off restructuring payment. An apparently meaningful margin can therefore conceal several different questions. Finance needs a result for the activity being tested before Tax can assess its pricing.

The calculation was simple; its assumptions were not

Suppose the UK service activity has an assumed eligible cost base of £2 million. For illustration only, the group has selected and independently supported a 5% mark-up for that activity. This is neither a recommended rate nor a safe harbour.

On those assumptions, the indicated service revenue is £2.1 million. Only £1.9 million has been recorded, leaving a £100,000 operating loss against those costs. An additional £200,000 would produce the indicated £100,000 profit.

That arithmetic is correct. It does not establish that £200,000 should be invoiced.

The reviewer still needs to establish whether all £2 million belongs in the relevant cost base, whether any revenue is missing from the calculation, whether the same service was provided throughout and whether the assumed method remains appropriate.

A genuinely omitted invoice under a supported pricing arrangement presents a different problem from a proposal to reimburse every unexpected expense. Both can appear as the same adjustment in a spreadsheet.

“Routine” does not settle who bears the loss

The group should avoid assuming that the UK company’s description as a routine service provider settles its entitlement to compensation. Equally, a loss does not establish that the pricing was wrong.

Businesses can incur genuine losses. Persistent losses in a purportedly low-risk activity warrant investigation, but neither an automatic profit guarantee nor an automatic acceptance of losses follows from the label.

For each material adverse item, the review should identify the relevant exposure, the contractual position, the people exercising control and the enterprise with financial capacity to assume it. The reward for contributions to risk control also needs consideration; identifying the risk bearer does not complete the pricing analysis.

Suppose, for example, the principal required a costly customer-support programme and the UK company delivered it as instructed. The inquiry differs from a case in which the UK company independently committed resources outside the service mandate. The evidence should establish what each enterprise agreed to provide and how independent parties would have priced those obligations.

Calling both items “exceptional” does not answer that question.

Separate the correction from the new commercial decision

The reconciliation may reveal that the implemented arrangement was sound but invoices did not follow it. A properly supported correction can then implement the existing pricing terms.

Alternatively, the arrangement may have changed. Perhaps the UK team now performs additional technical work, or a temporary activity has become permanent. The next step may be a fresh analysis and a prospective change in terms, with appropriate treatment of the intervening period.

These are different decisions. A year-end invoice should not obscure when the service changed or make an unsupported assumption appear to have applied throughout the year.

The original restructuring consideration must also remain separately identifiable. A service-fee adjustment is not, by itself, a revision to the price of transferred contractual rights. Nor does a poor first year automatically establish that the original valuation was wrong. Any contingent price mechanism, valuation uncertainty or further compensable change needs its own review.

The route into the accounts and return matters

The CFO also needs to know whether the proposal changes the actual intercompany price, corrects an accounting error or adjusts taxable profits only.

Under the UK’s basic transfer-pricing rule, an adjustment addressing a UK tax advantage generally increases taxable profits or reduces losses. It does not provide a general right to reduce UK profits merely because a different arm’s-length price would have produced less UK tax. Specific relief routes require separate consideration.

HMRC’s compliance guidance therefore encourages timely monitoring and distinguishes price changes reflected in the accounts from later computational adjustments. The distinction becomes particularly important when the proposed correction would reduce UK profits.

For this group, the practical instruction is to agree the nature, support and accounting treatment of the adjustment before approving the close. An invoice dated in December does not, on its own, resolve recognition, deductibility or the period to which the payment belongs.

Both countries need to understand the same payment

An additional UK service invoice generally creates a corresponding expense claim for the principal. That does not establish that the overseas jurisdiction will accept the deduction, timing or character.

Before posting it, the advisers should agree a common description of the service, calculation, supporting evidence and relevant period. Local requirements for invoicing, withholding tax or indirect taxes should be checked where applicable.

If the two countries disagree and the same profits are taxed twice, treaty relief may need consideration. A corresponding adjustment is not established simply by sending the counterparty a debit note. Access to the Mutual Agreement Procedure, procedural requirements and deadlines depend on the applicable treaty and circumstances.

The group should preserve its claim rights while investigating the difference. It should not budget on the assumption that an eventual bilateral resolution is assured.

The subsidiary adjustment does not complete the PE analysis

The UK company’s fee concerns dealings between separate enterprises. Any UK permanent establishment of the foreign principal requires a separate attribution exercise within that principal.

The fee may be relevant to that exercise, but it does not automatically settle the PE’s attributable profit. The reconciliation must explain how the subsidiary remuneration and the principal’s PE computation interact, avoiding both omissions and duplicated amounts.

Corporate residence remains separate again. If the variance investigation reveals a shift in strategic decision-making, that fact should be referred for a residence review. Adjusting a service invoice cannot determine where the principal is resident. UK domestic rules must also be read alongside the applicable treaty; domestic amendments do not rewrite treaty provisions.

What the CFO should approve

For the illustrative group, the useful closing paper would record four decisions:

• What caused each material variance, and which transactions and periods it concerns.
• Whether the existing method and cost base remain appropriate.
• Which correction or prospective change is supported, with its accounting and tax treatment in both countries.
• Whether any separate restructuring, PE, residence or treaty-relief review is required.

That paper should reconcile the approved amount to the ledger and retain the evidence behind judgmental items. It also gives the auditor and professional referrer a clear basis for identifying where specialist input is still needed.

The next question in the series is therefore: can the group explain every material adjustment by reference to the business, rather than simply the margin it wanted to report?
