Eligible Groups for Group Relief under UK Corporation Tax

Identifying the correct group structure is the first and most essential step before a company can explore group relief planning. Under UK Corporation Tax rules, group relief allows certain companies to transfer losses among themselves—but only if they meet the strict criteria to be considered an eligible group. The eligibility is based not just on ownership percentage but also on rights to profits and assets. A well-structured group can offer valuable tax-saving opportunities, but even a small shortfall in ownership may lead to loss of entitlement. Establishing eligibility from the outset is key to effective group relief planning.

This article explores which companies qualify as part of a group relief-eligible group, with clear definitions and multiple practical examples and a brief overview of how eligibility can also impact Capital Gains Tax and Stamp Duty Tax reliefs.

What is an Eligible Group?

For companies to qualify for group relief, they must form what is known as an eligible group. This exists when there is a sufficient level of ownership and control between the companies, specifically based on a 75% relationship.

To be considered an eligible group for group relief purposes, one company must meet all three of the following conditions in relation to another company:

These three tests together form the concept of beneficial and equitable ownership, and all three must be met. If even one condition is not satisfied, the companies will not be treated as part of a group for group relief purposes.

In addition, group relief also applies between two companies that are each owned to the extent of 75% or more by the same parent company. These are known as fellow subsidiaries, and although they may not hold shares in each other, they can still exchange group relief because of their common parent.

Direct and Indirect Ownership

Ownership can be direct (where a company holds the shares itself) or indirect (through a chain of subsidiaries). For indirect ownership, the percentages are multiplied along the chain to determine the effective interest.

Common Parent Company- Fellow Subsidiaries

Group relief is also available between two or more fellow subsidiaries, provided they are each owned to the extent of at least 75% by the same parent company. This is a common structure in large corporate groups where the parent company holds direct control over multiple trading subsidiaries.

Overseas Companies

Overseas companies can play a role in helping UK companies meet the 75% group ownership tests, but they cannot directly participate in group relief claims. Their presence is only relevant for tracing ownership between UK-resident entities.

To qualify for group relief, companies must be within the charge to UK Corporation Tax. This typically includes UK-resident companies and overseas companies with a UK permanent establishment (PE). However, foreign companies with no UK tax presence cannot claim or surrender losses, even if they are part of the ownership chain.

Other Reliefs Linked to 75% Group Ownership

While this article focuses on group eligibility, it’s worth noting that the same 75% ownership condition can also unlock additional tax reliefs within a corporate group structure. These include Capital Gains Tax (CGT) group relief and Stamp Duty Land Tax (SDLT) group relief.

The 75% group condition provides the foundation for accessing both CGT and SDLT reliefs, though each operates under a distinct set of rules and qualifying criteria.

Capital Gains Tax (CGT) Relief

Companies within an eligible 75% group may also benefit from CGT group relief. When assets are transferred between group members, they may qualify for no-gain/no-loss treatment, meaning the transfer occurs at no immediate tax cost. The gain or loss is effectively deferred until the asset is sold outside the group. This treatment supports internal restructures and reorganisations while preserving capital gains tax neutrality.

However, CGT group relief follows separate rules from Corporation Tax loss relief, including anti-avoidance provisions where the transferee leaves the group within six years.

Stamp Duty Land Tax (SDLT) Relief

Eligible group structures may also access SDLT group relief on land and property transfers. Provided the group relationship remains intact both before and after the transaction, no SDLT is payable. This relief is commonly used during intra-group property reorganisations, helping companies move assets efficiently.

SDLT relief is governed by its own set of rules and may be withdrawn if the group link is broken within three years of the transaction.

These CGT and SDLT reliefs will be explored in greater detail in a forthcoming article, where we will examine the qualifying conditions, technical rules, and practical considerations involved in applying them within a group structure.

Conclusion

Establishing eligibility for group relief under UK Corporation Tax requires a clear understanding of the 75% ownership conditions and the nature of beneficial and equitable ownership. Whether the relationship is direct, indirect, or through a common parent company, each connection must be carefully assessed to ensure the group meets the qualifying criteria. Even minor variations in shareholding percentages or structure can prevent companies from accessing valuable reliefs.

Recognising the impact of eligible group status goes beyond just loss transfers. It can also open the door to broader reliefs such as Capital Gains Tax and Stamp Duty Land Tax reliefs, both of which rely on the same underlying ownership thresholds. A properly structured group not only ensures compliance but also offers strategic advantages in tax planning and internal restructuring. A strong grasp of eligibility rules is therefore essential for maximising tax efficiency within corporate groups.
