Can a solicitor submit an SDLT return based on specialist advice for Property Trader Relief?

Introduction

Buyers sometimes receive specialist Stamp Duty Land Tax advice after exchange or close to completion, especially where a relief is being claimed. A common practical problem then arises: the conveyancing solicitor is willing to file the SDLT return, but only if the client confirms that the technical tax position comes from a separate adviser and that the client accepts responsibility for the claim.

This issue often comes up where Property Trader Relief is being claimed under Schedule 6A to the Finance Act 2003. Readers usually want to know whether that arrangement is normal, whether the solicitor can rely on the tax adviser’s position, and what the buyer must do to protect themselves if HMRC later asks questions.

The Question

A company buying a property wanted to claim Property Trader Relief from SDLT. The buyer had obtained specialist SDLT advice and intended to send that advice to the conveyancing solicitor so the SDLT return could be completed on that basis.

The solicitor replied that they would submit the return if the client confirmed three points:

• that the client had obtained advice from a competent tax adviser;
• that the solicitor was not responsible for the technical content of the SDLT return where it was based on that advice; and
• that the client would take responsibility for dealing with any HMRC enquiry or dispute arising from the claim.

The buyer therefore needed wording that clearly confirmed those points and explained that the relief being claimed was Property Trader Relief under paragraph 3 of Schedule 6A to the Finance Act 2003.

Nick’s Explanation

Nick’s response was to provide a clear confirmation letter for the solicitor’s file. In substance, the letter said that the buyer had obtained specialist SDLT advice, that the solicitor was filing the return on the basis of that advice, and that the buyer accepted responsibility for the return and any consequences if HMRC later challenged it.

The key points in Nick’s approach were:

• the client should expressly confirm that specialist SDLT advice had been obtained from a competent adviser;
• the solicitor should be told that they were not being asked to verify the technical merits of the relief claim;
• the client should accept responsibility for the self-assessment position taken in the SDLT return; and
• the solicitor should be given enough information to file the return using the relief claimed.

Nick also made clear, in later correspondence, that if HMRC were to open an enquiry it would help if the adviser had formal engagement terms and authority to act. He also noted that ongoing compliance matters could be important, including the buyer’s future intentions for the property and any renovation work, because Property Trader Relief depends on the statutory conditions continuing to be met.

The Law

SDLT is a self-assessed tax under the Finance Act 2003. The purchaser is the taxpayer and is legally responsible for the accuracy of the land transaction return, even where a solicitor or agent physically submits it.

Property Trader Relief is contained in Schedule 6A to the Finance Act 2003. Broadly, the relief can apply where:

• the purchaser is a qualifying property trader;
• the acquisition is made for the purposes of the property trading business;
• the relevant statutory conditions are satisfied; and
• none of the disqualifying conditions applies.

Paragraph 3 of Schedule 6A is commonly the key operative provision for the relief. The detail matters. Relief is not available simply because a company says it intends to resell a property. HMRC and the courts will look at the legislation closely, including the nature of the buyer’s business, the purpose of the acquisition, and whether the property is held as trading stock rather than for investment or occupation.

Where a property is said to be uninhabitable or not suitable for use, that is a separate SDLT issue and not the same as Property Trader Relief. In those cases, the threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. A property will not be treated as unsuitable for use as a dwelling merely because it needs repair, refurbishment or modernisation.

Analysis

The first point is responsibility. In SDLT, the purchaser remains responsible for the tax return. A solicitor may prepare and file the SDLT1, but that does not transfer the underlying tax liability or legal responsibility for the correctness of the return. So, as a matter of practice, it is entirely understandable that a conveyancer may ask for written confirmation where a specialist relief claim is being advanced by someone else.

The second point is the division of roles. A conveyancing solicitor often deals with completion mechanics and filing formalities. A specialist SDLT adviser may deal with the tax analysis. Where those roles are separated, it is sensible for the file to record:

• who advised on the relief;
• what relief is being claimed;
• that the solicitor is acting on the basis of that advice; and
• that the client accepts the tax position being taken.

The third point is whether Property Trader Relief is actually available. That depends on the statutory facts, not on the wording of the letter. A confirmation letter can help the solicitor feel able to file the return, but it does not itself create entitlement to relief. If HMRC opens an enquiry, the buyer must still prove that the requirements of Schedule 6A were met.

The fourth point is evidence. If a buyer is claiming Property Trader Relief, they should expect HMRC to ask for supporting material if the case is reviewed. That may include:

• company records showing a genuine property trading business;
• board minutes or internal records showing the purpose of acquisition;
• accounts treatment consistent with trading stock rather than investment property;
• evidence of intended resale; and
• documents showing that the property is not being retained for letting, occupation, or another non-qualifying purpose.

The fifth point is post-completion conduct. Nick was right to flag that future intentions and renovation plans matter. Relief can be jeopardised if the buyer’s actions show that the property was not acquired or held for the qualifying trading purpose. A buyer should therefore make sure that the real commercial position stays aligned with the basis on which the SDLT return was filed.

The sixth point is formal engagement. If HMRC later raises questions, it is much easier for the adviser to assist if they have proper terms of engagement and authority to act. That is not what determines whether the relief exists, but it is important from a practical enquiry-management perspective.

Outcome

The practical answer is yes: a solicitor can submit an SDLT return based on specialist SDLT advice, provided the position is properly documented and the client accepts responsibility for the tax analysis.

A written confirmation to the solicitor is a sensible step. It should say that the buyer has taken specialist advice, that the solicitor is filing on that basis, and that the buyer accepts responsibility for the return and for dealing with any HMRC enquiry.

However, that only deals with the filing process. The buyer must still make sure that Property Trader Relief genuinely applies under paragraph 3 of Schedule 6A to the Finance Act 2003 and that the facts remain consistent with the claim.

Practical Steps

If you are in this position, the sensible next steps are:

1. Check exactly which SDLT relief is being claimed and under which statutory provision.
2. Make sure the advice is in writing and sets out the factual assumptions clearly.
3. Give the solicitor a short confirmation that they are filing on the basis of specialist advice and that you accept responsibility for the tax position.
4. Keep evidence showing why the acquisition qualifies for Property Trader Relief.
5. Ensure the company’s accounting treatment and business records match the claimed trading purpose.
6. Review any planned renovation, occupation, letting or resale activity to make sure it does not undermine the relief conditions.
7. Put formal authority in place if you want the adviser to deal directly with HMRC in the event of an enquiry.

If the argument instead relates to whether the property was uninhabitable or not suitable for use as a dwelling, assess that separately and cautiously. Following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799, the condition threshold is now relatively high.

Conclusion

Where a specialist adviser says Property Trader Relief is available, a conveyancing solicitor may reasonably ask the client to confirm that the solicitor is relying on that advice and is not taking responsibility for the technical SDLT analysis. That is a normal risk-management step. The important point is that the buyer remains legally responsible for the SDLT return and must be able to support the relief claim under Schedule 6A to the Finance Act 2003 if HMRC asks questions later.
