LTT Group Relief: Key Definitions for Companies in the Same Group
LTT group relief can remove Welsh land transaction tax on transfers within a corporate group, but only if strict legal definitions are met. The main points are that companies must fall within the statutory meaning of the same group, the 75% test involves more than share ownership alone, and wider concepts such as control, arrangements and timing can affect both whether relief is available and whether it is later withdrawn.
- Companies are usually in the same group if one is a 75% subsidiary of the other, or both are 75% subsidiaries of the same parent.
- The 75% test requires at least 75% entitlement to ordinary share capital, distributable profits and winding-up assets, not just 75% of the shares.
- The position is tested at the effective date of the land transaction, so the group structure at that time is critical.
- Control has a technical meaning taken from corporation tax law and can depend on voting rights, governing documents and other powers, not only legal ownership.
- Arrangements are defined very widely and can include informal understandings as well as legally binding agreements.
- Complex share rights, indirect holdings, joint ventures and withdrawal rules can make the analysis difficult and may require close review of constitutional documents and related agreements.

LTT group relief: key definitions that determine whether companies are in the same group
This page explains the main defined terms used in the Welsh rules on LTT group relief. These definitions matter because group relief depends heavily on technical concepts such as “same group”, “75% subsidiary”, “control” and “arrangements”. If you misunderstand those terms, you can easily reach the wrong answer on whether relief is available or whether it may later be withdrawn.
What this rule is about
Group relief is intended to remove LTT charges on certain land transactions within a corporate group. But the relief is only available, and only remains safe, if the parties fall within precise statutory definitions.
The source material is a definitions page. It does not itself set out the full conditions for relief. Instead, it explains the meaning of terms used elsewhere in the group relief rules. In practice, these definitions do much of the real work. They tell you:
- when companies are treated as being in the same group,
- what level of ownership is needed,
- what counts as control,
- how joint venture companies are identified, and
- which transactions are treated as “relieved transactions”.
What the official source says
The official material defines a number of terms used in the LTT group relief guidance.
“Arrangements” is defined very widely. It includes any scheme, agreement or understanding, whether or not it is legally enforceable. This is important because the rules are not limited to formal contracts. Informal understandings may also matter.
“Company” means a body corporate. The source notes that this includes a limited liability partnership, although it also says the group relief rules apply to LLPs only in very specific ways.
Companies are members of the same group if one is the 75% subsidiary of the other, or both are 75% subsidiaries of a third company. For one company to be the 75% subsidiary of another, three tests must all be met. The parent must be beneficial owner of at least 75% of the ordinary share capital. It must also be beneficially entitled to at least 75% of the profits available for distribution to equity holders. And it must be beneficially entitled to at least 75% of the assets available for distribution to equity holders on a winding up. The source says these entitlements can be held directly or through other companies, applying the rules in sections 1155 to 1157 of the Corporation Tax Act 2010.
For deciding entitlement to distributable profits or winding-up assets, the source applies the rules in Chapter 6 of Part 5 of the Corporation Tax Act 2010, but with certain provisions treated as omitted. That means the test is not just a simple share-counting exercise. The rights attached to shares and the wider corporation tax rules can affect the answer.
“Constitutional document” means the memorandum or articles of association, or a similar document regulating the affairs of a joint venture company.
“Control” takes its meaning from sections 450, 451 and 1124 of the Corporation Tax Act 2010. In broad terms, it means the power to secure that the company’s affairs are conducted in accordance with a person’s wishes. That power may arise through shareholdings, voting power, or powers given by the articles or other governing documents. The source also makes clear that different control provisions are relevant in different parts of the group relief rules. For restrictions on the availability of relief, section 1124 is used. For certain cases where relief is not withdrawn when the seller leaves the group, control is determined under sections 450 and 451.
A “group company” is a company which, at the effective date of the land transaction, is in the same group as the purchaser or seller.
A “joint venture company” is a company with two or more member companies, carrying on a commercial activity governed by an agreement regulating the affairs of the members.
“Member” has a different meaning depending on context. In relation to a company, it means a company in a group of companies. In relation to a joint venture company, it means a holder of shares or securities in that joint venture company.
“Mortgage” is defined differently across the UK’s legal systems. In England and Wales and Northern Ireland it means any legal or equitable charge. In Scotland it means any right in security.
A “non-group company” is simply a company that is not a group company.
“Ordinary share capital” means all issued share capital, by whatever name called, except share capital that only gives a right to a fixed dividend and no other right to participate in the company’s profits.
“Relevant associated company” has a technical meaning linked to the withdrawal and non-withdrawal rules. In the main definition, it means a company in the same group as the buyer immediately before the buyer ceases to be in the same group as the seller, where that company also leaves the seller’s group as a consequence of the buyer leaving. The source notes that this definition is modified for the rules dealing with cases where group relief is not withdrawn under paragraph 9.
“Relevant transfer of business or engagement” means certain transfers to which building societies relief, friendly societies relief, or co-operative and community benefit society and credit union relief would apply, as described in Schedule 22.
A “relieved transaction” is a land transaction relieved from LTT because a claim to LTT group relief has been made.
What this means in practice
The practical point is that group relief depends on more than a simple corporate chart.
Many readers assume that if Company A owns 75% of the shares in Company B, that is enough. The source shows that this is not always sufficient. You must also check economic entitlement. The parent must usually have at least 75% of:
- ordinary share capital,
- distributable profits, and
- winding-up assets.
If a company has unusual share rights, preference shares, restricted rights, or bespoke constitutional arrangements, the answer may not be obvious from the share register alone.
The timing also matters. Whether a company is a “group company” is tested at the effective date of the land transaction. So a transaction may qualify or fail depending on the group structure at that particular point.
The wide definition of “arrangements” matters because anti-avoidance or withdrawal provisions often look beyond legally binding steps. If there is an understanding that a company will leave the group, or that ownership will change, that may be relevant even if documents have not yet been signed.
The definition of “control” also matters because legal ownership is not the only way to influence a company. Voting rights, constitutional rights, and powers under other governing documents can all be relevant. In some parts of the rules, the exact statutory definition of control changes, so it is important to identify which paragraph of the group relief rules you are applying.
How to analyse it
A sensible way to approach these definitions is to work through the following questions.
- What transaction are you testing? First identify the land transaction and its effective date.
- Who are the purchaser and seller? Then identify which companies need to be in the same group for relief to apply.
- Is there a 75% group relationship? Check whether one company is a 75% subsidiary of another, or whether both are 75% subsidiaries of a third company.
- Do all three 75% tests work? Check ordinary share capital, entitlement to distributable profits, and entitlement to winding-up assets. Do not stop at legal ownership of shares.
- Are there indirect holdings? If ownership runs through intermediate companies, apply the corporation tax rules referred to in the source.
- Are there unusual share rights or constitutional provisions? Review articles, shareholder agreements, and any other governing documents.
- Is “control” relevant to the point you are testing? If so, make sure you are using the correct statutory control definition for that part of the rules.
- Are there any arrangements in the background? Consider formal and informal understandings, not just signed contracts.
- Is the structure a joint venture rather than a straightforward group? If so, the joint venture definitions may matter and the analysis may be more complex.
- Is the issue about withdrawal of relief rather than initial entitlement? If yes, terms such as “relevant associated company” may become important.
Example
This is an illustration only.
Parent Ltd owns 80% of the ordinary shares in Sub Ltd. On the face of it, that looks enough for group relief. But suppose another class of shares gives an outside investor a large entitlement to Sub Ltd’s profits and winding-up proceeds. Parent Ltd may still own 80% of the ordinary share capital, yet fail the separate 75% tests for profits or assets on a winding up. If so, Sub Ltd may not be a 75% subsidiary for group relief purposes, even though Parent Ltd has a clear majority shareholding.
The lesson is that you must examine the rights attached to the shares, not just the headline percentage.
Why this can be difficult in practice
These definitions are technical because they borrow from corporation tax legislation. That means the answer may depend on cross-referred rules rather than the LTT guidance alone.
Difficulty often arises where:
- the share structure is not simple,
- there are preference shares or special rights,
- profits and winding-up entitlements do not match voting rights,
- ownership is held through several companies,
- there are joint venture arrangements, or
- the issue is not initial eligibility but whether relief is later withdrawn.
Another source of difficulty is that “control” does not always mean the same thing in every part of the rules. The source expressly points to different statutory provisions depending on the paragraph being considered. So it is unsafe to assume that one general understanding of control will answer every question.
The definition of “arrangements” is also deliberately broad. In practice, that can bring in informal plans or understandings that parties may not initially think are relevant.
Key takeaways
- For LTT group relief, being in the “same group” usually requires more than owning 75% of the shares; profits and winding-up rights must also be checked.
- The relevant tests are applied at the effective date of the transaction, and informal “arrangements” may still matter.
- Technical terms such as control, joint venture company, and relevant associated company can affect both entitlement to relief and whether it is later withdrawn.
