HMRC has designated two structures used by the adviser ‘Property118’ as “tax avoidance schemes”. Property118 are appealing to a tax tribunal, and have asked their clients to provide witness statements. That’s perfectly normal. But what’s not normal at all is that Property118 are directing the content of the witness statements.
It would be serious professional misconduct for a solicitor or barrister to coach a witness in this manner, and the witness statements may now be inadmissible.
The background to the Property118 tax appeal can be found in our previous reports here.
The request for witness statements
It’s usual for a party to a dispute to ask interested third parties to provide witness statements. Court rules require that witness statements from a person should be made in their own words.
That’s not the approach Property118 took in a message they sent their clients on 18 September:
![Message from Property118 to members asking for witness statements to support their Substantial Incorporation Structure appeal at the First-tier Tribunal: Dear Members,
We are reaching out to ask for your support in a very important matter concerning the Substantial Incorporation Structure (SIS) and Capital Account Restructure (CAR), which many of you have used as part of your incorporation strategy. As you may be aware, HMRC is currently challenging the SIS structure, claiming that it is driven by tax motivations rather than its clear commercial benefits.
We firmly believe that SIS and CAR were chosen for their practicality and commercial advantages and not primarily for tax purposes. To help demonstrate this to the First-tier Tribunal (FTT), we are requesting witness statements from clients and their accountants who can share their experiences and reasons for choosing SIS. Your witness statement will be a critical piece of evidence to show that the decision to use SIS was based on sound commercial reasoning.
What We're Asking You to Do:
We are asking for volunteers who are willing to provide witness statements describing why you or your clients chose SIS. These statements will be used to show that the decision to incorporate using SIS was driven by its commercial benefits, such as:
• Deferred refinancing costs.
• The ability to retain legal title while transferring beneficial ownership.
• Avoiding the immediate administrative burden and costs of remortgaging.
• The flexibility that SIS offers for managing property portfolios.
The Strategy Behind the Witness Statements:
In these witness statements, we want to highlight that the decision to use SIS and CAR was primarily based on commercial practicality—not on tax advantages. The statements will cover:
• Why SIS was chosen over other incorporation methods.
• How SIS allowed you or your clients to manage liabilities, avoid the costs and hassle of immediate refinancing, and preserve flexibility in managing property portfolios.
• An acknowledgment that while tax benefits are a factor, they were not the main motivation—the focus was on achieving the best commercial outcome.
How to Volunteer:
If you're willing to provide a witness statement, please either:
• Post a comment in the forum to volunteer, or
• Email [redacted]@Property118.com to let us know you're interested.
Once we've received your expression of interest, we'll follow up with a witness statement template and guidance to help you prepare your statement.](https://taxpolicy.org.uk/wp-content/uploads/2024/10/Untitled-5.jpg)
This is not merely asking for witness statements; it’s directing what they should say: “In these witness statements, we want to highlight that the decision to use [the structure] was primarily based on commercial practicality – not on tax advantages”.
Mark Alexander, the founder of Property118, then provided his clients with a list of points to add into their witness statements:

And Property118 have a template they have “95% prepared”:
![Online forum exchange between Jacqueline and Mark Alexander of Property118: Jacqueline [redacted]
For me, as I approached retirement I was worried about repaying finance and passing the business onto my offspring. I also had commercially favourable mortgage deals that I didn't want to refinance without being fully in control of it being the right move commercially. The business was viable and I'd put my life's work into it, but if I had to repay my mortgages, I'd have to sell a lot and effectively downsize and dismantle the business for not commercially-sensible reasons. By incorporating I could ultimately take out Ltd. Co mortgages that went with the company when it made commercial sense to do so. I also had relationship dynamics with previous partners that meant I needed to cover various bases, whilst honouring past input and being flexible as circumstances fluctuated. Incorporation gave me a new structure that replace my outdated partnership arrangements.

Perfect!
You could add all of those points into the template we have 95% prepared for you.
Please email [redacted]@Property118.com to request the template.
Also, would your Accountant be prepared to back you up on this?](https://taxpolicy.org.uk/wp-content/uploads/2024/10/Untitled-4.jpg)
There seems to be some awareness that it is improper to template witness statements – “similar is good, identical is not”:
![Screenshot of an online discussion between an unnamed user and Mark Alexander on Property118 regarding witness statements: [redacted]
We are also more than happy to provide a witness statement and our reasons were similar to those already expressed:
Not wanting to pay early repayment charges on 10 mortgages, totalling thousands of pounds.
Not wanting to pay new mortgage arrangement fees also totalling thousands of pounds.
Not wanting to move to less appealing mortgage rates and also pay for the privilege.
Wanting to provide a structure that would allow us to handover the business and responsibility in the future to our children.
I'll email Yvonne as you say to request the form.

Thank you, much appreciated.
Similar is good, identical is not. Please use your own words.

The messages above come from Property118’s client forum. Two Property118 clients were so alarmed at what they were being asked to do that they (independently) spoke to lawyers, who contacted us with their clients’ permission.
The consequences
We discussed the likely consequences of Property118’s approach with two tax KCs and two solicitors specialising in tax litigation.
Solicitors and barristers have a duty not to mislead a court or tribunal. It would be serious professional misconduct for a solicitor or barrister to coach a witness or seek to influence the content of a witness statement. The courts have been very unhappy when presented with witness statements which were in reality written by a legal team, not the witness.
We and the lawyers we spoke to thought it was highly unlikely that Property118’s legal team had agreed to this approach. It was much more likely that Property118 were obtaining the witness statements behind the backs of their legal team.
That, however, presents a problem. When and if Property118’s legal team becomes aware of how the witness statements were obtained, it is unclear how they will be able to present them to the tribunal.
Witness statements drafted in this way would probably not be admissible in a civil court1. Tax tribunals have more flexibility2, but we would expect a barrister to be required to, at the least, draw the tribunal’s attention to the fact that a witness statement was, to a significant degree, prepared by Property118 and not the witness. That would then likely undermine the weight the Tribunal gave to the witness statement.
The substance of the issue
The difficulty Property118 are having reflects a common problem faced by promoters of tax avoidance schemes. A judge will expect an answer to the question: “why did you enter into this transaction?” The real answer is: to avoid tax. But if the promoter gives that answer, they’ll likely lose. So they struggle to find some other answer – anything, other than tax. Property118’s attempt to construct witness statements should be seen in this context.
Property118 marketed a structure for landlords. The structure involved the landlords declaring a trust in favour of a company. This supposedly enabled landlords to achieve all the benefits of incorporating their business – lower tax rate, full deduction for mortgage interest, and capital gains tax and potentially inheritance tax advantages. But it avoided all the messy disadvantages of incorporation: needing a new mortgage, having to tell tenants, and moving all the contracts associated with the business.
None of that actually worked as a technical matter. But even if it had, there’s a basic problem with the proposition. The trust structure has no benefit other than tax.
If you incorporate a business in the usual way, that will have a large number of legal and commercial implications. Some are desirable; some are not. But the many changes that flow from the incorporation mean that you can’t usually look at someone incorporating a business and say “this is mainly being done for tax reasons”. There’s too much going on.
Property118’s trust structure had only one benefit: a tax advantage.
Property118 are trying to coach their witnesses into answering the question: “why did you use the Property118 structure instead of incorporating?” That’s the wrong question. The correct question is “why did you use this structure instead of keeping things as they were?”
The only answer to that is: tax.
The main benefit, and perhaps sole benefit, of the structure was tax, and that’s why Property118’s appeal will likely fail.
