Higher SDLT rates: the HMRC contents guide explained
Higher SDLT rates at a glance

- Joint buyers are tested separately.
- Replacing a main home has detailed conditions.
- Ownership records and move dates are vital evidence.

Higher SDLT rates: the HMRC contents guide explained
If stamp duty on a second home worries you, this HMRC page maps guidance on extra SDLT rules for additional homes, joint buyers, companies and people replacing the home they live in. It is not an answer.
What this rule is about
Higher SDLT rates can add a substantial amount to the tax due on a residential purchase. People often call this the extra stamp duty on a second home.
Useful shorthand. But it can hide important details.
The key question is not simply whether you have owned another property: the law looks at who is buying, what they are buying, what they own at the end of the relevant day, and whether they are replacing their main home. Small facts can change the result.
What the official source says
HMRC’s source page does not set out a rule or give an example; it is a contents page for a group of HMRC manual pages about the higher SDLT rates. The manual is HMRC guidance, not the law.
The contents page directs readers to sections covering these subjects:
- the higher SDLT rate bands
- the test for one home bought by an individual
- joint purchases and how each buyer is tested
- purchases of two or more homes at once
- what counts as a home for these rules
- the rules for replacing the home you live in
- spouses, civil partners, trusts and children
- companies and other non-individual buyers
- partnership interests and recent inheritances
- transitional rules and changes to rates
The legislation has separate tests for different kinds of purchase. For a joint purchase, it tests each buyer on their own.
If the higher-rates test is met for any one buyer, it can apply to the whole purchase. That can decide the result.
What this means in practice
Do not treat the contents page as a checklist that proves you must pay more tax; use it to find the guidance matching your situation, then test the facts against the legislation. Start with the right section.
This is where people go wrong: ownership on the relevant day can matter even when an old home is sold soon afterwards, although that later sale may still matter and its route and timing need careful checking. Dates matter.
- List every person buying the property.
- List every home each buyer owns, including shares.
- Include homes outside England and Northern Ireland where the rules require this.
- Check whether a spouse or civil partner is living with the buyer.
- Check whether the purchase is replacing a main home.
- Keep records of any sale of the former main home.
Buying through a company is not the same as buying personally. Nor is buying an extra share in a home always the same as buying a new one.
The manual contents page flags both issues because they have their own rules. They need separate checking.
How to analyse it
Start with the facts, in date order. Labels such as “second home” or “buy-to-let” do not settle the issue.
The legal test is more specific.
- Identify the SDLT date for the purchase.
- Identify every buyer and their relationship to one another.
- Check whether the purchase includes one home or several.
- Check the amount paid and the type of property interest bought.
- List other homes held at the end of that day.
- Check the value and lease position of each other interest.
- Decide whether the new home is intended to replace the buyer’s main home.
- Check the date and circumstances of any sale of the old home.
- Review special rules for a company, trust, partnership or inheritance.
For an individual buying one home, the legislation includes a £40,000 test for the amount paid and a £40,000 market-value test for another home held at the end of the day. Lease length can matter too.
Example
Alex buys a flat for £300,000. At the end of completion day, Alex still owns a buy-to-let flat worth £160,000.
Alex is not selling a former main home as part of a move. On those facts, the extra SDLT rules can apply.
Change one fact: if Alex is buying a new main home and sells the former main home within the statutory period, the later sale may allow the SDLT position to be corrected. The exact route, time limit and evidence still matter.
Why this can be difficult in practice
Many cases turn on documents that people do not gather until after completion. That makes a quick answer risky.
What you intended, where you lived and what interest you actually owned can all matter, especially when the documents, ownership records and real use of the property point in different directions. Details decide cases.
- A share in a home can count; full ownership is not always needed.
- A property inherited recently may need separate checking.
- A short lease and a long lease can produce different results.
- A separated couple may not be treated in the same way as a couple living together.
- An annexe or land within a property’s grounds can affect what has been bought.
- Rate changes mean the purchase date should always be checked.
You might think a conveyancer’s description of the property settles the question. It does not.
The ownership records, contracts and real use of the property are more likely to decide it. Check the evidence.
Key takeaways
- HMRC’s page is a contents list, not a personal SDLT decision.
- The higher-rate test depends on the buyer, property and timing.
- Keep evidence of ownership, occupation and any sale of an old home.

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 contents page cannot answer whether a particular building, annexe, leasehold interest or parcel of land counts as a home.
- Whether a new purchase replaces a main home can depend on evidence of occupation, intention, sale timing and any intervening purchase.
- The supplied source does not give the facts needed to decide a particular buyer’s position.
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 purchase contract and completion statement — the property bought, price, buyers and completion date
- Land Registry title and filed plan for every property — each person’s legal ownership and the land included
- Lease documents and any variation deeds — the remaining lease term and whether an interest is reversionary
- Sale contract and completion statement for the old home — whether and when the former main home was sold
- Council tax bills, electoral-roll entries and utility bills — where the buyer actually lived over the relevant period
- Mortgage papers, insurance records and correspondence about the move — the intended use of the new home and the move timetable
- Marriage, civil partnership, separation or divorce records — whether spouse or civil-partner rules affect the result
- Trust deeds, probate papers and inheritance records — interests held through a trust or received by inheritance
- Partnership agreement, accounts and property records — whether a partnership interest needs to be counted
- Valuation evidence for other homes or shares in them — whether another interest meets the statutory value test
