Old SDLT mistake claims: when HMRC had to make enquiries
HMRC has archived this page because it describes an older process for mistakes in an SDLT return, rather than the route for a new stamp duty claim. It is not the route for a new stamp duty claim.
What this rule is about
A land transaction return is the form used to report stamp duty. The old paragraph 34 process dealt with a claim that the return contained a mistake.
The key feature was an enquiry. Under that former process, HMRC had to enquire into the claim instead of simply treating it as settled. That was required.
What the official source says
For claims from 1 April 2011, HMRC says the legislation for paragraph 34 changed, and it labels this guidance obsolete while directing readers to newer material. Readers should use that newer material.
- The page concerns an old paragraph 34 rule.
- Its topic is a required HMRC enquiry.
- It does not describe the newer claim process.
What this means in practice
Check the date of the claim first, rather than only the date you bought the property, because that date determines whether this archived material could matter at all. Start there.
- Do not rely on this page for a recent claim.
- Keep the original SDLT return.
- Keep letters showing whether HMRC opened an enquiry.
How to analyse it
Start with the claim’s timeline, then identify which version of the law applied and whether the issue was a mistake in the return at that time. Record the answer.
- When was the claim made?
- What mistake was said to have happened?
- Which paragraph 34 version applied then?
- Did HMRC send an enquiry notice?
Example
Sam finds a tax error in an old return and sees this manual page. If Sam’s claim was made from 1 April 2011, the page itself says that newer guidance should be used instead, even though the old return and manual page remain visible. The archive alone cannot decide the claim.
Why this can be difficult in practice
People often focus on the purchase date. That may not answer the procedural question. The former and later systems should not be mixed up.
- An old return does not automatically mean old claim rules apply.
- HMRC’s archived manual is not legislation.
- The relevant dates and correspondence may be missing.
Key takeaways
- This page covers an obsolete process.
- It concerned mandatory HMRC enquiries.
- Claims from 1 April 2011 need newer rules.

Official guidance
The pages below are HMRC’s guidance. Guidance is not law. It sets out how HMRC 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. HMRC can also change or withdraw guidance, and it may not cover your facts.
Where this is not settled
- This archived page does not explain the full wording, time limit or scope of the former claim process.
- A claim needs to be matched to the law in force when it was made.
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 date of the claim
- the SDLT return and any later changes
- the claimed mistake and supporting documents
- any HMRC enquiry letters or decisions
