LTT and co-ownership authorised contractual schemes
CoACS and LTT
A CoACS is generally treated like a company when it deals with Welsh land. Its operator handles the LTT duties, while transfers of participant rights are outside LTT.
- Each umbrella-scheme pool is separate for LTT.
- Land moved between pools can be an LTT property deal.

LTT and co-ownership authorised contractual schemes
If a co-ownership authorised contractual scheme, or CoACS, buys land in Wales, it is mostly treated like a company for LTT. LTT is Wales’s stamp duty-style land tax. Instead of each investor, the scheme’s operator handles the tax duties.
What this rule is about
A CoACS is a type of investment fund. Investors put money into the fund, receive and hold rights in it, and do not own every property directly in their own names. It holds the properties.
That distinction matters when the fund buys, sells, or moves property in the course of its investment activity, including activity carried out through a pool. Section 36 identifies the buyer for LTT purposes and explains how an umbrella fund is divided.
In simple terms, the tax concerns the scheme’s dealings in property, rather than routine changes in the persons who hold rights in the fund. That is the distinction.
What the official source says
The WRA guidance says that a CoACS which acquires land counts as a company for LTT and tax administration. For participants, the guidance treats their rights as if they were shares in that company.
- The operator must do things that the buyer would normally have to do.
- Issuing rights to participants is outside LTT.
- A participant giving up rights is outside LTT.
- Transferring rights between participants is outside LTT.
- A CoACS cannot, simply by being treated as a company for these purposes, claim group relief, reconstruction relief, or acquisition relief under section 36. The treatment does not extend that far.
It also says that an umbrella CoACS has separate pools of investments. Participants can exchange rights in one pool for rights in another.
Each pool counts as its own CoACS. For LTT, the umbrella fund as a whole does not count as one scheme.
What this means in practice
Moving rights in a fund is not the same as moving the land held by the fund. That distinction can be easy to miss.
When a pool buys Welsh land, or transfers land to another pool under the same umbrella fund, its operator must assess the LTT position for that particular pool. In that situation, the transfer is a property deal for LTT purposes.
- Identify the particular pool that owns or is buying the land.
- Record the operator responsible for that pool.
- Check whether a transfer between pools is notifiable.
- Do not assume a group relief claim is available.
Here is where people can go wrong: common ownership under one umbrella does not make a transfer between pools disappear for LTT.
How to analyse it
Start with the fund documents. Labels alone will not answer the question. You need to know how the scheme is set up and which pool holds the property.
- Is the scheme a CoACS within section 36?
- Is it an umbrella scheme with separate investment pools?
- Which pool owns the land before the deal?
- Which pool will own it afterwards?
- Is the change a transfer of land, rather than a transfer of participant rights?
- Must the buyer make an LTT return for the property deal?
- Is anyone assuming that a company relief applies when section 36 excludes it?
A supplied WRA page also describes an EEA-based scheme. Do not rely on that wording by itself for a current transaction. It does not match the current section 36 text supplied here.
Example
Imagine an umbrella CoACS with a retail-property pool and a housing-property pool. A Welsh building is owned by the retail pool. The operator moves that building into the housing pool. Although the same umbrella fund remains involved, the law treats the two pools as separate schemes. The move is therefore a property deal for LTT, and the operator must check whether it is notifiable and whether a return is due.
Now change the facts. An investor transfers rights in the retail pool to another investor while the pool continues to hold the building, without any transfer of that building taking place. The building stays put. This is a transfer of fund rights, not a transfer of the building. The guidance says it is outside LTT.
Why this can be difficult in practice
Fund structures are often complicated. Documents that describe the umbrella arrangement may sit alongside separate documents that set out the rules applying to an individual pool and its investments in practice. Both may matter.
You might think that one operator and one umbrella name settle the matter. They do not. What matters is the separate pool.
- A transfer between pools may look internal but can still be a property deal.
- Participant rights must be separated from the land held by the scheme.
- The source’s statement about the market value rule needs current-law review.
- The source’s EEA description also needs checking against current law.
Key takeaways
- A CoACS is mostly treated like a company for LTT.
- The operator deals with the scheme’s LTT duties.
- Each umbrella-fund pool is a separate CoACS for LTT.

Official guidance
The pages below are the Welsh Revenue Authority’s guidance. Guidance is not law. It sets out how the Welsh Revenue Authority reads the legislation, and it is not binding on you, on a tribunal or on a court. Where guidance and the legislation differ, the legislation wins. the Welsh Revenue Authority can also change or withdraw guidance, and it may not cover your facts.

Where this is not settled
- The WRA page’s statement about the deemed market value rule appears out of date when compared with the supplied current text of LTTA 2017 sections 22 and 36.
- The page also contains an EEA-based description which does not match the current definition shown in the supplied text of section 36. The guidance needs checking before it is relied on for a current transaction.
Evidence you would need
This kind of case is decided on the facts of the individual property. These are the records that usually settle it, and the ones an adviser would ask you for.
- The scheme authorisation order and scheme documents.
- Details of the operator responsible for the scheme.
- For an umbrella scheme, documents showing each separate pool and any transfer between pools.
- The property deal documents and facts needed to decide whether a return is required.
