Company purchases of shares in the same home: the SDLT higher charge
When separate company purchases are added together
For this SDLT rule, linked purchases of separate shares in the same home can be combined. If the total is more than £500,000, each relevant share may be treated as above the higher threshold.
- The transactions must be linked.
- Connected companies can be involved.
- The facts and paperwork behind the deal matter.

Company purchases of shares in the same home: the SDLT higher charge
Company purchases of shares in the same home: the SDLT higher charge
Buying a home in stages does not always avoid the higher stamp duty charge. If connected companies buy separate shares in the same home as part of linked deals, SDLT can add the prices together. That can change the tax position for every linked purchase.
What this rule is about
Rather than the extra charge people usually call the stamp duty surcharge on a second home, this is a special SDLT charge for certain company-led purchases of high-value homes. The distinction matters.
Here, the law looks at the whole deal, not just one slice of it. A company cannot treat a smaller first share purchase as an isolated transaction.
That distinction can matter a great deal.
What the official source says
HMRC’s manual says the SDLT rules combine separate rights in the same home when the purchases are linked. Buyers can acquire the relevant rights at the same time or over time.
The threshold is £500,000. Above that combined amount for the relevant rights, the legislation requires this treatment. Rent is left out of that total. Each relevant right then counts as a higher-threshold interest for this Schedule.
- The deal must include a right in or over one home.
- At least one other deal must involve a right in or over the same home.
- The deals must be linked under the SDLT rules.
- The combined amount for the relevant rights and related rights must exceed £500,000.
- The higher charge also requires the separate company or similar buyer condition in Schedule 4A.
- Deals involving certain collective tenant rights or crofting community rights are excluded from this rule.
Linked does not just mean that two deals look similar. Under the law, they must form part of one scheme, arrangement or series involving the same buyer and seller, or people connected with them.
What this means in practice
A later purchase can reach back. It may affect an earlier one if the rule applies. That is the feature people most often miss. The later step may show that the total deal was above the threshold all along.
HMRC’s manual gives an example where this leads to a return for the later deal and a further return for the earlier deal to report extra tax. This is HMRC’s guidance for its example, not a complete filing guide for every situation.
- Do not assess each share purchase on its price alone.
- Check who owns and controls every buying company.
- Check whether one seller, or connected sellers, are involved.
- Keep papers that explain why each step happened.
- Review the SDLT position when a later share is bought.
How to analyse it
Start with the steps that actually happened. Labels in contracts are not enough. The outcome depends on more than contractual labels: it turns on the rights transferred, the people involved, and whether all the steps belonged to a single planned series.
- List every purchase of a share or other right in the home.
- Record the buyer, seller, date and amount paid for each step.
- Check whether each step concerns the same home.
- Work out whether the steps form one scheme, arrangement or series.
- Check whether buyers or sellers are connected under the statutory test.
- Add the amounts attributable to the relevant rights, leaving out rent.
- Check whether the total is more than £500,000.
- Then check whether the company-led higher-charge condition applies.
What actually decides it? Usually, the links between the steps. Separate paperwork proves little. Different completion dates do not, by themselves, establish separate deals.
Example
HMRC’s example dates from 2014. A company buys a 40% share in a freehold home for £400,000. At that point, the amount is below £500,000. Later, another company in the same group buys the remaining 60% from the same individual for £1 million, so the group’s companies hold all the shares in the home. That matters.
The two payments total £1.4 million. On the stated facts, HMRC treats the deals as linked. Both shares are therefore treated as higher-threshold interests. HMRC’s example makes the point clear by showing how an acquisition made later can change the SDLT outcome of an earlier purchase.
Why this can be difficult in practice
Although the arithmetic is usually easy, deciding whether the purchases really form one arrangement or series is difficult. That needs evidence, not guesswork.
You might think different companies make the deals separate. They may not. Connected companies can still fall within the linked-transaction rule.
- A group structure may be more complex than the names on the transfer deeds suggest.
- One deal may have been planned before the first contract was signed.
- The price may cover land or rights beyond the home itself.
- Documents must substantiate any genuine independent reason for a later purchase.
- The source cannot determine every company purchase outcome or address every possible Schedule 4A exception.
Key takeaways
- Linked purchases of shares in one home can be added together.
- Connected companies do not automatically make separate deals separate for SDLT.
- A later purchase can change the tax treatment of an earlier one.

Official guidance
The pages below are HMRC’s guidance. Guidance is not law. It sets out how HMRC reads the legislation, and it is not binding on you, on a tribunal or on a court. Where guidance and the legislation differ, the legislation wins. HMRC can also change or withdraw guidance, and it may not cover your facts.
Where this is not settled
- Whether purchases form one scheme, arrangement or series can depend on the full commercial background.
- Whether companies, buyers or sellers are connected needs checking against the statutory connected-person rules.
- The amount properly attributable to each right may be unclear where a deal includes other land, rights or obligations.
- The source uses a 2014 example. The result for a real transaction also depends on its effective date and any other Schedule 4A rules that apply.
Evidence you would need
This kind of case is decided on the facts of the individual property. These are the records that usually settle it, and the ones an adviser would ask you for.
- signed contracts, transfer deeds and completion statements for every purchase — the parties, dates, price and exact rights transferred
- Land Registry title registers, title plans and filed deeds — who owned each share before and after each step
- a dated timeline of negotiations, exchange, completion and payments — whether the steps were planned as one arrangement or series
- company group chart and Companies House records — whether the buying companies were connected
- shareholder registers, trust documents and control agreements — who controlled the buyers and any connected parties
- board minutes, investment papers and internal deal approvals — the purpose and planned sequence of the purchases
- bank statements, invoices and funding agreements — what was paid and whether funding was coordinated
- valuation reports and price-allocation schedules — how much of the total amount relates to the home and related rights
