For UK businesses expanding overseas, the Controlled Foreign Companies (CFC) rules are a vital area of international tax. They determine when profits held in an overseas subsidiary can be taxed back in the UK.

Controlled Foreign Companies tax advice from TaxDigit accountants

What Is a Controlled Foreign Company?

A Controlled Foreign Company is a non-UK resident company controlled by UK residents. The rules exist because a group could otherwise route profits through a low-tax overseas subsidiary instead of bringing them home. What matters is who really controls the company, not simply where it is incorporated.

Why the Rules Matter

The Controlled Foreign Companies regime protects the UK tax base from artificial profit diversion. It is not designed to penalise genuine trade: most ordinary overseas activity falls outside a CFC charge, especially where the company has real substance and pays meaningful local tax.

The Main Exemptions

Several exemptions mean many subsidiaries never face a charge, including the exempt period, tax, excluded territories, and low profits exemptions. Each has detailed conditions and thresholds that are reviewed periodically, so current rules should always be checked.

For multinational groups operating in the UK, Action 13 compliance is a central part of transfer pricing documentation. It reshaped how large groups report where their profits are earned and taxed.

Action 13 compliance and transfer pricing documentation advice from TaxDigit

What Is Action 13?

Action 13 introduced a three-tiered approach to transfer pricing documentation: a master file overview of the group, a local file covering specific transactions, and country-by-country (CbC) reporting. Together these give tax authorities a clearer picture of global activities.

Who Needs to Comply?

CbC reporting generally applies to large groups above a global revenue threshold. Even without full CbC reporting, many groups still need master and local files, so Action 13 compliance is relevant to a wide range of international businesses.

Why It Matters

The aim is transparency. Consistent documentation across jurisdictions helps authorities spot mismatches between where activity happens and where profits are reported, and it is also a business’s first line of defence in any enquiry.

How TaxDigit Can Help

Our Guildford-based team helps groups meet their Action 13 compliance obligations with clear, defensible documentation. Get in touch to review your transfer pricing position.

Frequently Asked Questions

What is Action 13 compliance?
Action 13 is the OECD standard for transfer pricing documentation, introducing the master file, local file and country-by-country reporting so tax authorities can see where group profits are earned and taxed.

Does my group need country-by-country reporting?
Full CbC reporting generally applies to large groups above a global revenue threshold, but many smaller groups still need master and local files.

Thin capitalisation is a key concept in UK corporate tax, especially for groups that fund their operations through debt. It describes a situation where a company is financed with a relatively high level of debt compared to equity, often to take advantage of tax-deductible interest.

Thin capitalisation and intra-group debt tax advice from TaxDigit accountants

What Is Thin Capitalisation?

A company is said to be thinly capitalised when it carries more debt than it could realistically borrow on its own as an independent business. Because interest is generally deductible while dividends are not, groups can be tempted to load a UK company with intra-group debt to reduce taxable profits.

Why HMRC Takes an Interest

The UK’s transfer pricing rules require that intra-group borrowing reflects what would have been agreed between independent parties. Where a company is thinly capitalised, HMRC may disallow part of the interest deduction, treating the excess borrowing as something an unconnected lender would not have provided.

Managing the Risk

Groups can manage thin capitalisation risk by reviewing debt levels, interest rates and guarantees against arm’s length standards, and by keeping clear documentation. The Corporate Interest Restriction rules may also limit deductions separately, so both regimes need to be considered together.

Frequently Asked Questions

What is thin capitalisation?
A company is thinly capitalised when it carries more debt than it could have borrowed as an independent business, often to maximise tax-deductible interest. UK transfer pricing rules can deny the excess deduction.

Why does HMRC scrutinise thin capitalisation?
Because interest is deductible while dividends are not, groups can load a UK company with intra-group debt to reduce taxable profits, so HMRC tests whether the borrowing is at arm’s length.

Can TaxDigit help if I am not based in Guildford?
Yes. We advise on thin capitalisation for clients UK-wide, remotely and from our Guildford office.
