Stamp Office Guidance on Customer Queries and Information Requests for SDLT

Where to send SDLT questions, ruling requests, and payment deferral applications

HMRC deals with SDLT enquiries in different ways depending on the type of issue. Routine questions should normally go to HMRC’s stamp duty helpline first, but formal requests, such as applications to defer payment where consideration is contingent or uncertain, and requests for pre-transaction or post-transaction rulings, should be sent to the Stamp Office.

• Use HMRC’s helpline for straightforward SDLT information requests.
• Send applications to defer SDLT payment on contingent or uncertain consideration to the Stamp Office.
• Send both pre-transaction and post-transaction ruling requests to the Stamp Office.
• The purchaser or their agent may make the enquiry, and HMRC says they will be updated on progress.
• The main practical issue is deciding whether the matter is a simple query or a formal case-specific request.

Where to send SDLT questions, ruling requests, and applications to defer payment

This page explains what HMRC’s SDLT manual says about asking for information or assistance on more technical Stamp Duty Land Tax matters. The key practical point is that not all SDLT queries go to the same place. Straightforward questions are meant for HMRC’s helpline, but formal applications such as requests to defer payment for contingent or uncertain consideration, and requests for pre-transaction or post-transaction rulings, should be sent to the Stamp Office.

What this rule is about

The source material is about routing SDLT enquiries correctly within HMRC. That matters because some issues are simple information requests, while others are formal applications that may affect how a transaction is reported or when tax must be paid.

In particular, the manual identifies three types of matter:

• applications to defer payment where the consideration is contingent or uncertain
• requests for pre-transaction rulings
• requests for post-transaction rulings

HMRC treats these as matters for the Stamp Office rather than ordinary helpline handling.

What the official source says

HMRC’s manual says that:

• applications to defer payment in cases involving contingent or uncertain consideration should be sent to the Stamp Office
• requests for both pre-transaction and post-transaction rulings should also be sent to the Stamp Office
• the purchaser or their agent will be told about the progress of the enquiry
• straightforward requests should first be made to the HMRC helpline for stamp duty enquiries

The manual also points the reader to other SDLT manual sections dealing with deferred payment applications and rulings.

What this means in practice

The practical message is simple: if your issue is routine, start with the helpline. If your issue is a formal technical application or ruling request, send it to the Stamp Office.

This distinction matters because a formal application is not just a request for general guidance. It is usually asking HMRC to deal with a specific legal or procedural issue arising from an actual or proposed land transaction.

For example, where the price includes an amount that depends on a future event, or cannot yet be fixed with certainty, the buyer may need to consider whether an application to defer payment is available. That is not something the manual suggests dealing with through a basic helpline query.

Likewise, if a party wants HMRC’s view before entering into a transaction, or wants a ruling after the transaction, the manual directs that request to the Stamp Office.

How to analyse it

A sensible way to approach this is to ask four questions.

1. Is this just a straightforward information request?
   If yes, the manual says it should be made to the helpline in the first instance.
2. Am I asking HMRC to deal with a formal application?
   If the issue is deferral of payment because consideration is contingent or uncertain, the manual says it should go to the Stamp Office.
3. Am I asking for a ruling on a transaction?
   If you want a pre-transaction or post-transaction ruling, the manual says this should also go to the Stamp Office.
4. Who should make the enquiry?
   The manual refers to the purchaser or agent being updated on progress, which indicates that either may be involved in making the approach.

In practice, the first step is to identify whether you are seeking general assistance or making a formal request that requires HMRC to consider the facts of a particular case.

Example

Illustration: A buyer is acquiring land and part of the price will only become payable if planning permission is granted in the future. The buyer is not just asking a general SDLT question. They may need to consider whether this is a case of contingent or uncertain consideration and whether an application to defer payment should be made. Under the manual, that application should be sent to the Stamp Office, not dealt with as a routine helpline enquiry.

Why this can be difficult in practice

The source material is brief and does not define what counts as a “straightforward” request. That means there can be a judgement call at the start.

Some enquiries begin as apparently simple questions but turn out to involve a formal issue about the treatment of a specific transaction. In those cases, the important practical step is to recognise when the matter has moved beyond general guidance.

The manual also refers the reader to other sections for the substantive rules on deferred payment applications and rulings. So this page is mainly about where the enquiry should be sent, not about the legal test for whether HMRC will agree with the request.

Key takeaways

• Routine SDLT questions should usually be raised with HMRC’s helpline first.
• Formal applications to defer payment for contingent or uncertain consideration should be sent to the Stamp Office.
• Requests for pre-transaction and post-transaction rulings should also go to the Stamp Office.
