Land Transaction Tax opinion: when you can rely on it only if the deal matches your request
Land Transaction Tax opinion: when you can rely on it only if the deal matches your request
A Welsh Revenue Authority tax opinion can help with a Land Transaction Tax question. It protects only the person who asked for it, and only where the facts they gave remain the facts on which the transaction proceeds in practice. A changed detail can matter.
What this rule is about
A tax opinion is WRA’s view on a particular transaction. It is not a general answer that anyone can use for a similar property deal.
The key point is simple: the real deal must match the deal WRA considered.
What the official source says
According to WRA, reliance on an opinion is available only in limited circumstances, where the requestor, the facts and the transaction all match what WRA considered. Those circumstances are set out below.
- You gave WRA accurate information.
- You carried out the transaction as you described it.
- You were the person who requested the opinion, or that person’s agent.
- The opinion relates to that particular transaction.
What this means in practice
Keep the request, the opinion and papers that support the facts you gave, because they may show why the opinion applies to your deal when the final terms match the request. Keep them together.
- Check the final terms against the request.
- Tell WRA about a material change before relying on the opinion.
- Do not assume an opinion obtained by somebody else covers you.
How to analyse it
Start with the opinion itself. Then compare it with what actually happened, rather than relying on its headline answer.
- Who asked WRA for the opinion?
- Which transaction does it identify?
- Was every relevant fact accurate?
- Did the completed deal follow that description?
Example
Amir asks WRA for an opinion about his planned purchase and gives details of the deal, which he may rely on only if they are accurate and he completes that deal as described. If the deal changes, the opinion may no longer cover it.
Why this can be difficult in practice
People often focus on the answer in the opinion, not the facts behind it. That is the mistake. The source does not say exactly which changes are too significant, so the documents and the wording of the opinion matter.
- A later change may mean this is no longer the same transaction.
- Missing or inaccurate facts can prevent reliance.
- Where a deal is part of avoiding or evading tax, you cannot rely on an opinion.
Key takeaways
- Accurate facts are essential.
- The completed deal must match the request.
- An opinion is personal and transaction-specific.
