When companies can face the 17% SDLT rate on a home
A company buying a home for more than £500,000 can face stamp duty at 17%. This is not the extra rate for a second home. It is a separate, much higher rate for certain company and investment buyers.
What this rule is about
The rule targets high-value homes bought through companies and similar structures. The key question is not simply who will live there. It is whether the purchase meets the threshold and buyer tests.
The amount paid for the home must be more than £500,000. At exactly £500,000, this particular 17% rule does not apply.
That distinction can be expensive. A small change in the amount paid may bring different SDLT rules into play.
What the official source says
HMRC’s manual says that the 17% charge applies where a higher-threshold home interest is bought by a company, certain partnerships, or for a collective investment scheme.
- A company can be caught, but not if it is a public body or acts as trustee of a settlement.
- A partnership can be caught when at least one member is a company that is not a public body.
- A purchase for a collective investment scheme can be caught.
- A partnership involving such a scheme can also be caught.
- Joint buyers are caught if just one of them meets one of those tests.
- The home interest must have more than £500,000 attributed to it.
HMRC’s manual is guidance, not law. The legal test is in Schedule 4A to the Finance Act 2003.
What this means in practice
If your solicitor says a company purchase may face 17%, check the structure early, because calling the buyer a property business does not by itself answer whether the threshold, buyer tests, and exclusions point to that rate. Check it early.
There are exclusions for some genuine business and trading activities. These have conditions. The intended use of the property matters.
- Check whether the buyer is a company, rather than an individual.
- Check every member of a buying partnership.
- Check whether an investment arrangement is being used.
- Check whether the purchase is linked to another purchase of the same home.
- Check whether a business exclusion may apply before assuming 17% is due.
This is the part people can miss: a joint purchase does not avoid the rule merely because another joint buyer is an individual.
How to analyse it
Work through the questions in order. Check the price and property mix first, because starting with the buyer alone can otherwise produce the wrong answer.
- Is the main thing bought a home interest?
- Is more than £500,000 attributed to that home interest?
- Does the transaction include another interest, such as non-residential land?
- If so, must the transaction be split for this test?
- Are linked purchases of interests in the same home relevant?
- Is the buyer a company, a relevant partnership, or acting for an investment scheme?
- Is the company only acting as trustee of a settlement?
- Does a statutory business or trading exclusion apply?
For an investment scheme, the label is not enough. The financial-services definition decides whether it is a collective investment scheme.
Example
Northfield Ltd buys a house for £600,000. Assume the purchase is a high-value residential transaction and no exclusion applies. The 17% rate produces SDLT of £102,000: 17% of £600,000.
Now change one fact. If Northfield Ltd buys the same house for £500,000, it remains outside the higher threshold for this particular rule, although that fact alone does not settle its SDLT bill or determine the rules that may still apply. This 17% rule does not apply.
Why this can be difficult in practice
Property structures serve many parties and purposes. People reviewing the paperwork may not plainly see who is buying, why they are buying, or whether purchases are linked when a structure contains several parties or purposes. Read it closely.
- A company may buy as trustee, in its own right, or in both roles.
- A partnership agreement may reveal a company member that was overlooked.
- A property business may not meet every condition for an exclusion.
- Several contracts can together pass the higher threshold for the same home.
- A premium and rent must be kept separate when a lease is granted.
For a lease, HMRC’s manual says the 17% charge applies to a premium above the threshold. SDLT on the rent follows the normal rent rules instead.
Key takeaways
- The 17% SDLT rule is separate from the second-home extra rate.
- It can apply where more than £500,000 is paid for a home interest.
- Companies, relevant partnerships and investment schemes need careful checks.

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 a structure is a collective investment scheme can require a detailed review of how it operates.
- Business exclusions depend on the exact purpose of the purchase and the statutory conditions.
- The supplied legislation is current only to the dates recorded in the skills and should be checked for a later transaction.
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.
- The buyer’s legal form and, for a partnership, its members
- The contract, completion documents and total amount paid
- Details of any linked purchases involving the same home
- Documents showing the intended business use
- Lease documents separating the premium from the rent
