17% stamp duty when a company buys a high-value home
In brief
A company buying a home for more than £500,000 can face SDLT at 17% of the full price. The result depends on the buyer, the property, linked deals and any statutory business exclusion.
- Check the property facts, not just the sales description.

17% stamp duty when a company buys a high-value home
A company buying a home for more than £500,000 can face stamp duty land tax at 17% of the full price. That is a very different charge from the extra rate on a second home. It can add up fast, but it does not apply in every company purchase.
What this rule is about
Certain high-value homes bought through a company or similar structure are targeted by this rule. The law calls these buyers “non-natural persons”. In everyday terms, that usually means a company, some partnerships involving a company, or an investment fund.
The key figure is £500,000. If more than that is fairly allocated to one home, the special charge may be in play. The 17% rate applies to the whole amount paid for that home, not only the part above £500,000.
That distinction sounds harsh. It can decide a six-figure tax bill.
The HMRC page behind this article is a contents page. It links to HMRC’s detailed manual chapters on the charge, what counts as a home, exclusions, later loss of relief, returns and special arrangements. HMRC’s manual is guidance, not the law itself.
What the official source says
HMRC groups its guidance under Schedule 4A of the Finance Act 2003. Under that Schedule, the 17% charge can apply where a high-value residential purchase is made by a company, by a partnership with a company member, or for a collective investment scheme.
- The purchase must include an interest in one home.
- More than £500,000 must be attributable to that interest.
- The buyer must fall within one of the specified company or fund categories.
- If buyers purchase jointly, one buyer meeting the company condition can be enough.
- A company acting as trustee is not included in the company limb of this test.
- A public body is excluded from the company limbs.
- Linked purchases of interests in the same home can be added together for the £500,000 test.
A home can be a building, or part of one, used or suitable for use as a single home, or a building being built or adapted for that use. Gardens, grounds and land that benefits the home can be treated as part of it.
So calling part of a site “commercial” does not settle the point. What was bought, and how it was used or intended to be used, matters.
The legislation also deals with a purchase containing a high-value home and other property. It can split that purchase into separate parts for the 17% charge. A mixed package is not, by itself, an answer.
What this means in practice
If your solicitor has said that 17% applies, start with the basic question: who is buying the property? A limited company is the obvious case. A partnership or investment arrangement can need closer work.
Next, check the property rather than its label. A house with fields, workshops or separate land may need its price divided on a fair basis. The result can turn on title plans, use at completion and the deal documents.
- Check whether the company is buying one home for more than £500,000.
- Check whether several linked deals concern the same home.
- Identify every building and parcel included in the price.
- Record how each part was used at completion.
- Separate business evidence from assumptions about future use.
- Check whether the company will claim a statutory exclusion.
Several exclusions exist. The HMRC contents page covers property rental businesses, property developers and traders, homes genuinely made available to the public, lenders acquiring property through lending, staff accommodation, farmhouses and qualifying housing co-operatives.
These are not broad exemptions for any business that owns property. Each has detailed conditions. For example, an exclusion can fail where the property is intended for occupation by a connected individual or another person specified by the legislation.
This is the part people get wrong: a stated business intention is not always enough. The law may also test what happens later.
How to analyse it
Work through the facts in this order. Do not begin with the rate. First decide whether the special charge applies at all.
- Find the effective date of the purchase and check the law applying then.
- Identify the legal buyer: company, partnership, trustee or investment arrangement.
- List everything included in the deal, including land, rights and separate buildings.
- Decide whether any building counts as a home at that date.
- Work out the amount fairly attributable to each home.
- Check whether linked deals involve interests in the same home.
- Test every condition of any business exclusion against the evidence.
- Keep records showing the intended and actual qualifying use.
- Monitor the property for three years where the exclusion has ongoing conditions.
For qualifying property rental, development or trading businesses, relief is normally lost if the required conditions are not met during the three years after the relevant date. Limited protections can apply if an unforeseen event outside the buyer’s control makes the planned use unreasonable to expect.
If relief is withdrawn, the buyer must submit a further SDLT return within 30 days of the relevant date set by the legislation. That is why records after completion matter as much as the purchase file.
Example
Rosa Properties Ltd buys a house for £600,000. Assume it is a single home, no exclusion applies, and the company condition is met. The £500,000 threshold is passed because the price is more than £500,000. At 17%, the SDLT is £102,000: £600,000 multiplied by 17%.
Now change one fact. If £500,000 exactly is fairly attributable to the interest in the home, it is not a higher-threshold interest under this Schedule. The special 17% charge does not arise under this rule on those facts. Other SDLT rules may still matter.
Suppose instead that Rosa Properties Ltd buys the house for a qualifying rental business and meets every exclusion condition. The 17% charge may not apply. However, it must keep meeting the relevant conditions during the control period, or the relief can be withdrawn.
Why this can be difficult in practice
Rarely do the difficult cases involve an obvious company purchase of an ordinary house; more often, they concern estates, rural property, redevelopment sites, staff homes, holiday businesses, funds and land with more than one use. They are not straightforward.
What actually decides it? Often, documents made at the time. A later explanation can carry less weight than a title plan, survey, tenancy agreement, board record or a properly dated business plan.
- A building may look unfit to live in but still be suitable for use as a home.
- Gardens, grounds and benefit land can be part of a home for this test.
- A deal split into two contracts can still be linked.
- Buying through a company does not automatically mean 17% is due.
- Running a business does not automatically create an exclusion.
- Use by an owner, relative or connected person can affect a business exclusion.
- A relief claimed at completion can later be withdrawn.
The 17% rate in this article reflects the supplied statutory text, which is current only to 17 November 2025 for Schedule 4A. For a later purchase, the applicable law and rate need checking against the current official legislation.
Key takeaways
- A company purchase of a home worth more than £500,000 can trigger SDLT at 17%.
- The 17% rate is charged on the full amount allocated to the home.
- Business exclusions can apply, but they have detailed conditions and may be withdrawn later.

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
- A property cannot be classified from its description alone. The boundaries, use of land, condition of buildings and arrangements at the effective date can change the answer.
- The supplied Schedule 4A legislation is recorded as current only to 17 November 2025. The applicable rate and conditions must be checked against current official legislation for a transaction after that date.
- Whether a business exclusion applies can turn on the buyer’s genuine commercial plans, actual use and who may occupy the property.
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 contract, transfer and completion statement — what was bought, the price and the relevant transaction date
- Land Registry title, title plan and any filed plans — the legal extent of each parcel, rights and separate interests
- Estate-agent particulars, sales brochure and auction pack — how the property and land were described when marketed
- Dated photographs, aerial images and site plans — the layout, boundaries and actual condition around completion
- Survey, valuation and building-condition reports — whether a building was usable or suitable as a home
- Planning history, lawful-use certificates and building-control records — permitted use, building works and legal restrictions
- Room-by-room use records and utility bills at completion — how each building or part of it was actually being used
- Council tax, business-rates and VAT records — official rating treatment and evidence of business use
- Tenancy agreements, grazing agreements and other occupation licences — who used the land or buildings and for what purpose
- Company accounts, business plans, board minutes and occupancy policies — the buyer’s commercial purpose and whether an exclusion was intended
