For years, SDLT has been treated as a routine part of the conveyancing process. The fee earner handling the transaction calculates the tax, completes the return and submits it to HMRC before registration. It is familiar, embedded and widely accepted.
But familiarity does not always mean it is the right structure.
Across a busy conveyancing team, hundreds or even thousands of SDLT returns may be submitted to HMRC each year as part of routine transaction work. That volume alone reinforces the fact that SDLT is not simply an administrative step, but a recurring tax compliance activity embedded within the transaction process.
According to HM Revenue and Customs, SDLT generates more than £11 billion in tax revenue each year. That scale raises a simple question. Why are tax returns of this volume being handled within a legal workflow rather than a structured compliance process?
Where the current model starts to show strain
In most firms, SDLT still sits with the fee earner progressing the transaction. On paper, this feels efficient. The person closest to the deal completes the return and keeps things moving.
In practice, SDLT is often handled:
- towards the end of the transaction, under time pressure
- alongside competing priorities such as exchange and completion
- with different approaches taken across teams
None of this is necessarily problematic on a single file. But across a high volume of transactions, these small variations begin to create inefficiencies. Time is spent rechecking figures, dealing with last-minute queries and managing corrections after submission.
A process sitting in the wrong place
The issue is not about whether conveyancers are capable of completing SDLT returns. It is that SDLT is fundamentally different from the rest of the conveyancing process.
It is:
- a self assessed tax return
- submitted directly to HMRC
- dependent on accurate classification and inputs
- part of a wider tax compliance framework
That makes it a compliance function as much as a legal one.
When that type of task sits within individual workflows, it tends to rely on personal experience rather than structured process. As firms grow, consistency becomes harder to maintain and inefficiencies are repeated across a larger volume of work.
Why firms are starting to rethink SDLT
As transaction volumes increase and processes come under greater scrutiny, firms are beginning to step back and look at SDLT more strategically. The focus is shifting away from how the return is completed on an individual file, and towards how the process operates across the firm as a whole.
In practical terms, that usually leads to one of three approaches:
- retaining SDLT within fee earner workflows but introducing more oversight
- centralising SDLT within a dedicated internal team
- separating SDLT from conveyancing and treating it as a distinct function
The common thread is clear. Firms are looking for greater consistency, better control and a more efficient use of fee earner time.
Where Compass fits
This is exactly the gap Compass was designed to address.
Rather than leaving SDLT within individual workflows, Compass introduces a structured approach that sits alongside the conveyancing process. SDLT is handled consistently across all transactions, reducing reliance on individual knowledge and removing duplication of effort.
The impact is practical. Fee earners spend less time on SDLT, processes become more predictable and firms gain clearer oversight of how SDLT is being managed.
A simple question for firms
Most firms already recognise the value of structure in areas such as client care, lender compliance and risk management.
The question is whether SDLT should continue to sit within the same informal structure it has always occupied, or whether it should be treated as a distinct part of the transaction process.
If SDLT were introduced today, it is unlikely it would be placed entirely in the hands of individual fee earners. It would almost certainly be designed as a structured, repeatable process.
That is the shift now beginning to happen.
