When do you need to file an SDLT return?
Most property purchases in England and Northern Ireland need an SDLT return. That can be true even where no stamp duty is due. The key issue is whether the deal is “notifiable”, the legal term for a transaction that you must report to HMRC, even when you owe no tax. That question comes first.
What this rule is about
Stamp duty land tax is not only about paying tax. It also has a reporting system. If your purchase is notifiable, you must send HMRC a land transaction return.
For ordinary freehold and leasehold purchases, reporting is the starting point. The law then sets out limited exceptions. A zero tax bill therefore does not, by itself, show that there is nothing to file. Check the reporting rule too.
The supplied law normally sets the deadline at 14 days after the effective date, although some arrangements can make the relevant date differ from completion. Completion often provides that date.
What the official source says
HMRC’s manual tells people to report most deals involving a major interest in land when they give something in return, unless an exemption or an exception applies. A major interest usually means a freehold or leasehold interest.
The legislation makes a purchase of a major interest notifiable unless one of the exceptions in section 77A applies, so the statutory exceptions determine whether reporting is needed. The legislation controls.
- A deal exempt under Schedule 3 does not need a return.
- The non-lease exception applies when the amount paid, plus linked deals, is less than £40,000.
- A long lease has its own exception where non-rent payment is less than £40,000 and relevant yearly rent is less than £1,000.
- Assignments and surrenders of leases have separate tests.
- The short-lease exception can apply when the amount paid does not go above the zero-rate threshold.
- Even if you claim relief, you may still need to submit a return.
Here is an important detail. HMRC’s source page says the £40,000 limit is “not greater than £40,000”. The supplied legislation says “less than £40,000”. On that wording, exactly £40,000 does not fit this exception.
What this means in practice
Do not use the final tax figure as your only check. You may pay no SDLT because the rate is 0% or because you claim a relief. Yet the deal can still need a return.
That catches people out. A return reports the transaction to HMRC; it is not simply a method of paying tax.
- Check reporting before assuming your conveyancer has nothing to file.
- Include the amount paid for linked property deals when testing the £40,000 exception.
- Keep the documents that show why an exception or exemption applies.
- Do not treat a relief claim as the same thing as an exemption.
- For a lease, identify whether it is a grant, an assignment or a surrender.
How to analyse it
Start with the deal itself, then work through the exceptions. The facts matter more than the label used in an email or on a form.
- Is the land in England or Northern Ireland?
- Are you buying a freehold or leasehold interest?
- What is the effective date for the deal?
- Is the transaction exempt under Schedule 3?
- Is it a lease, and if so, what type of lease transaction is it?
- What is the total amount paid for this deal?
- Are there linked deals with the same seller, buyer, or connected people?
- Are you relying on a relief rather than an exemption?
- If you need a return, can you file it within 14 days?
What makes deals linked? Before the linked-deals rules combine deals, they must form part of one scheme, arrangement or series involving the same parties, or people connected with them. Two documents may still be connected. Buying two plots under a single plan may matter even if there are two documents.
Example
Ravi buys a small piece of land for £39,999. It is not a lease, and there are no linked deals. On the supplied legislation, the £40,000 exception can apply because the amount is less than £40,000.
Change one fact: Ravi pays £40,000. The wording of section 77A no longer provides the exception. Ravi must then submit a return unless another exception applies. That single pound matters.
Why this can be difficult in practice
Deciding whether an exception genuinely applies is often harder than filling in a return, particularly where linked deals and lease payments make a simple-looking purchase more complicated. The form is not always the difficulty.
You might think a gift never needs reporting. Although Schedule 3 may exempt a gift with no payment, the full facts still matter, because taking over a debt may change the answer. Check what passes with the gift.
- Review several connected purchases together.
- A lease can involve rent as well as an upfront payment.
- An exemption and a relief have different reporting effects.
- The £40,000 test is less than £40,000, not £40,000 or less, in the supplied statute.
- HMRC manuals explain HMRC’s view, but they are not the law.
Key takeaways
- Most freehold and leasehold purchases need an SDLT return.
- No SDLT to pay does not always mean no return.
- Check exemptions, lease rules and linked deals before relying on the £40,000 exception.

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
- The article cannot determine whether a particular deal is linked without the full facts.
- The supplied statutory text is current only to 17 November 2025. Current-law checking is needed for a transaction after that date.
- HMRC’s wording about the £40,000 limit does not match the supplied statutory wording. The legislation takes priority.
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 contract, transfer or lease documents
- The effective date of the deal
- The amount paid under this and any related deals
- Details of the seller, buyer and any connected people or companies
- Details of any SDLT exemption or relief claimed
