Intercompany transactions are attracting growing attention from HM Revenue & Customs (HMRC), especially as more businesses operate across borders relying on different intercompany operating models. Recent changes to the VAT grouping Rules, including the ability for overseas establishments to join UK VAT groups, mean that arrangements previously thought to be straightforward may now need to be revisited.

What many organisations view as simple internal recharges such as management fees, cost allocations or inter-company pricing adjustments, can in fact create VAT liabilities. A common assumption is that these flows carry little real consequence because any VAT would ultimately be recoverable. However, failing to apply the reverse charge correctly can lead to years of underdeclared output VAT and substantial interest charges. In practical terms, this can equate to interest of around 36% over a four-year period on the VAT that should have been declared.

With HMRC scrutinising intragroup activity more closely than ever, it has become essential for businesses to ensure that the VAT treatment of intercompany transactions is accurate and defensible. This article highlights the key areas of risk and explains where businesses should take particular care.

VAT Grouping and Cross Border Establishments

The changes to VAT grouping rules represent one of the most notable developments for multinational groups. HMRC has now withdrawn the long-standing restriction that prevented overseas establishments of UK VAT group members from joining a UK VAT group. For businesses operating across several jurisdictions, this removes a significant limitation.

Where a UK establishment and its overseas branch are within the same VAT group, internal flows between them may no longer give rise to VAT. This can alter the treatment of cross border recharges and reduce unnecessary complexity. It also has retrospective relevance. Groups that applied the reverse charge under the previous rules may have overpaid VAT, particularly where input tax recovery was restricted. A review of historic entries may reveal opportunities to recover those amounts, subject to HMRC’s four-year time limit.

VAT Treatment of Intercompany Charges Outside VAT Groups

When one UK entity provides services to another within the same corporate group, such as management support or administrative functions, VAT is generally chargeable at the standard rate. This applies even where the purpose of the recharge is simply to allocate costs across the group. For VAT purposes, each company is treated as a separate taxable person, so internal recharges can still amount to supplies of services.

The position differs when both entities are members of the same UK VAT group. In that case, transactions between them are usually disregarded for VAT purposes.

However, businesses should not assume that all internal flows are automatically subject to VAT. Where payments represent pure reimbursements with no direct benefit to the payer, or where the payment does not constitute consideration for a supply, those flows may fall outside the scope of VAT. Careful analysis and appropriate documentation are essential to support this position.

UK Companies Receiving Services from Overseas: The Reverse Charge

When a UK business receives services from a non‑UK entity, whether within the same corporate group or from an external supplier, the reverse charge will generally apply. Under this mechanism, the UK recipient is required to account for VAT on the value of the services received and may then recover the same VAT to the extent allowed by its input tax recovery position.

These incoming cross‑border services also contribute towards the UK VAT registration threshold of £90,000. As a result, a UK entity with no domestic sales activity can still be required to register for VAT solely because it receives services from its overseas parent or affiliates.

Even where the UK entity is entitled to full recovery, the reverse charge must still be applied. HMRC regularly challenges failures to account for it, and repeated oversights can give rise to penalties as well as interest on the undeclared VAT. The belief that the reverse charge “nets off” remains a common misconception and often leads to cumulative errors over several VAT periods.

UK Companies Providing Services to Overseas Entities

When a UK business supplies services to a non-UK entity, whether within the same corporate group or to an external business, the place of supply rules generally places the transaction outside the scope of UK VAT. This often means no UK VAT is charged on the supply. However, this should not be mistaken for an absence of VAT obligations altogether.

Many jurisdictions operate their own version of the reverse charge, impose local VAT registration thresholds, or require non-resident businesses to register for VAT when providing certain services. As a result, the overseas recipient may have obligations in its own country, and in some cases the UK supplier may also face local compliance requirements depending on the nature of the service and the Rules of the jurisdiction involved.

International Operating Models and VAT

Intercompany pricing adjustments need careful consideration to determine how they interact with VAT. The key question is whether the adjustment relates to an underlying supply of services or goods, or whether the adjustment itself gives rise to a supply. Where the adjustment functions as a retrospective change to the price of a service, the VAT treatment should follow that of the original supply. In these situations, the adjustment may require VAT previously accounted for to be amended, or it may create a reverse charge obligation for the recipient.

However, not all intercompany transaction adjustments affect VAT. Many year‑end net margin-based adjustments do not change the economic value of what was supplied and therefore do not alter the consideration for VAT purposes. Establishing whether the adjustment genuinely reflects a change to the price of a supply is critical, and businesses should ensure this position is supported by clear documentation and consistent accounting treatment.

When intercompany pricing adjustments relate to goods, the focus changes from VAT to customs valuation. Adjustments may require amendments to import declarations and can increase duty liabilities if they result in higher dutiable values. Customs authorities may also review whether original import prices were correctly declared. As the reverse charge does not apply to goods, the primary risk in this area lies within customs compliance rather than VAT accounting.

Illustrative Example of VAT Exposure from Non-compliance

A simple example illustrates how easily VAT exposure can arise. Suppose a UK subsidiary receives an annual management charge of £100 from its United States parent company. If the UK entity fails to apply the reverse charge, HMRC may assess up to four years of under declared VAT for a non‑deliberate error. Even where the subsidiary is entitled to full recovery of input tax, interest will still be charged on the late declared VAT. Using HMRC’s interest methodology, which applies the Bank of England base rate plus 4%, the interest on four years of omissions could amount to approximately £36, assuming a base rate of 5%. Although the figure appears small in isolation, the cumulative impact can be significant when similar charges arise across several years, entities or jurisdictions.

Closing Thoughts

Although intercompany transactions are approached differently for direct and indirect tax purposes, the example illustrates how quickly VAT issues can arise. Internal group flows are often assumed to fall outside the scope of VAT or to create no real cost because any VAT would ultimately be recoverable. In practice, this assumption is a common source of non‑compliance. Even in the scenario wherein full input tax recovery is available, HMRC may still treat under‑declared output tax as an error and charge interest, with penalties applied if similar issues recur over multiple VAT periods.

With HMRC placing greater attention on intra‑group activity and recent changes to VAT grouping rules reshaping how cross‑border transactions are treated, it is important for businesses to reassess their arrangements. Reviewing the VAT treatment of intercompany charges and inter-company pricing adjustments can help reduce exposure, identify potential reclaim opportunities and support a stronger overall compliance position.
