Situation 04
Mixed-use property
Mixed use is a question of what the property actually is on the effective date, evidenced properly, not a label that can be applied to make a number smaller.
The short answer
This is the area of stamp duty where HMRC has been most active, and where weak claims have done the most damage to taxpayers who made them. A position that is right and evidenced is worth taking. A position that is hopeful is worth avoiding, and we will tell you which one you have.
Where this usually goes wrong
These are the patterns we see most often. Each one is a situation where the obvious answer and the correct answer are different.
Land is not automatically non-residential
Grounds, paddocks and outbuildings that come with a dwelling are frequently residential, and the fact that they are large does not change that on its own.
A use that ended before completion
What matters is the position at the effective date, not what the land was used for last year or what it might be used for next.
Evidence assembled after the event
A grazing licence signed after completion, or a commercial arrangement created to support a position, is worth less than nothing.
Following an adviser who is paid on the outcome
Claims made on this basis have led to enquiries, repayment with interest, and penalties. The taxpayer carries all of that, not the adviser.
Ignoring the consequences of getting it wrong
An incorrect claim is not a neutral punt. It has a cost, and the cost falls on the purchaser.
The facts that decide it
If you want to know where you stand before you speak to anyone, these are the questions we will ask. Having the answers ready is most of the work.
- 01What exactly is included in the title being acquired?The register and the plan tell us what is being bought, which is not always what the particulars describe.
- 02What was each part of the property actually used for on the effective date?Use is a question of fact, answered by what was happening rather than by what was possible.
- 03What documentary evidence exists for that use, dated before completion?We ask for records created at the time, because that is what a position has to rest on.
- 04Is there a genuine third party commercial arrangement in place?Who the parties are, what they did and what was paid all have to be capable of being shown.
- 05How is the land described in the contract and the marketing material?How the property was presented and sold forms part of the picture we have to reconcile.
- 06Has a return already been filed, and on what basis?What was declared determines whether the question is what to file or what to do next.
- 07Who advised on the position, and how were they paid?How an adviser is paid tells us a good deal about the incentives behind a position already taken.
- 08Is the property currently under enquiry?Where HMRC is already corresponding, the order in which things are done changes.
What we would want to see
The analysis is only as good as the documents behind it. For this situation, that normally means:
- Draft or executed contract, title register and title plan
- Evidence of the actual use of each part of the property
- Completion statement, where available
- Details of every property interest held
- Evidence of any disposal and its date
- Details of all purchasers and their positions
- Any existing SDLT return and UTRN
- Correspondence with the conveyancer on the point
Questions we get on this
The property came with several acres. Does that make it mixed use?
Not on its own. Size is not the test. What matters is what each part of the land actually was on the effective date and what evidence exists for it, which is why we start with the title and the use rather than the acreage.
Can we put a grazing agreement in place before completion?
A genuine arrangement entered into for genuine reasons is a fact. An arrangement created to support a claim is not, and it usually reads as such. We would want to see who the parties are, what was actually done under it and when it was signed.
A firm has offered to make the claim and take its fee from the refund. Should I?
That is your decision, but the purchaser carries the consequence of an incorrect claim, not the firm that made it. We would want to know what they have been told, what they have seen and what they propose to say before anything is submitted.
Will you just tell me what I want to hear?
No. Our fee is fixed and does not depend on the outcome, which means we have no interest in finding a saving that is not there. If the original return was right, we will tell you that in writing, and you will have a reasoned position on file if it is ever looked at.
