HMRC’s introduction of a new ‘tax adviser’ registration regime has understandably caused concern across the conveyancing sector. While much of the discussion has focused on accountants and tax practitioners, conveyancers are now finding themselves caught in the middle, particularly when it comes to Stamp Duty Land Tax (SDLT).
With implementation expected from May 2026, many firms are asking the same questions:
-
Who needs to register?
-
Does this apply at firm level or individual level?
-
What does this mean for SDLT advice within a conveyancing transaction?
At present, not all of these questions have definitive answers. However, what is clear is that conveyancers will need to be confident about where SDLT advice sits within their processes and who is ultimately responsible for it.
What is the new tax adviser status
HMRC is introducing a formal registration requirement for tax advisers who interact with HMRC on behalf of clients. The aim is to improve standards, accountability and transparency across the tax advice market.
Once implemented, registered advisers will receive a unique identifier and will be subject to ongoing obligations, including adherence to professional standards and potential sanctions for non-compliance.
While the policy intent is clear, the practical scope is still evolving, particularly for professions like conveyancing, where SDLT advice is often intertwined with legal work.
Why SDLT is a grey area for conveyancers
SDLT is a tax, but it sits inside a legal transaction. That alone makes it awkward.
Many conveyancers already feel uncomfortable being labelled as ‘tax advisers’, yet in practice they are expected to identify reliefs, apply higher-rate rules and submit accurate SDLT returns often under tight deadlines and with incomplete information.
The new regime raises an uncomfortable but unavoidable question: At what point does SDLT support become ‘tax advice’ in HMRC’s eyes?
HMRC has not yet confirmed whether registration will be required at individual level, firm level or both. Nor has it clarified how this applies where SDLT input is supported by third-party specialists.
Until that guidance lands, conveyancers are left managing risk in an uncertain environment.
Risk, liability and professional comfort
Even before the new tax adviser rules, SDLT has been an area of growing risk:
-
HMRC continues to challenge SDLT positions years after submission.
-
Error rates across SDLT returns remain high.
-
Reliefs are complex, fact-specific and frequently misunderstood.
Layer the new adviser regime on top of this, and it becomes increasingly difficult for conveyancers to justify carrying full responsibility for SDLT analysis without specialist backing.
For many firms, the issue is not capability, but professional exposure.
Where specialist SDLT support fits in
This is where specialist SDLT support models become increasingly relevant.
Using a dedicated SDLT advisory service allows conveyancers to:
-
Demonstrate that SDLT positions are reviewed by qualified tax professionals.
-
Reduce internal risk and reliance on fee earners interpreting complex tax rules.
-
Maintain a clear audit trail showing appropriate escalation of tax matters.
-
Continue to support clients effectively without straying into uncomfortable regulatory territory.
Importantly, this does not remove the conveyancer’s role. It strengthens it.
What conveyancers should be doing now
While we wait for further clarification from HMRC, there are sensible steps firms can take now:
-
Review current SDLT processes. Understand who is making SDLT decisions, and on what basis.
-
Document decision-making and escalation. Clear records will matter more than ever.
-
Avoid informal or unsupported tax opinions. Especially in complex or higher-risk cases.
-
Engage with specialist SDLT support early. Not as a last-minute fix, but as part of a structured process.
-
Keep clients informed. Transparency around how SDLT is assessed and supported builds trust and reduces complaints later.
Looking ahead
The introduction of HMRC’s tax adviser registration is not about catching conveyancers out. It is about raising standards and clarity across the tax system.
For SDLT in particular, it reinforces something many firms already know: this is no longer a side task or box-ticking exercise. It is a technical tax area with real financial and regulatory consequences.
Conveyancers who take proactive steps now by strengthening their SDLT processes and aligning with specialist support will be far better placed when the new regime goes live.
Uncertainty may remain, but one thing is clear: ignoring the issue is no longer an option.
