How SDLT tax bands work when you buy property
SDLT rates in brief
SDLT normally works through tax bands. Check the land type, the full amount paid, the purchase date, and whether another deal is linked.
- Each band applies only to part of the price
- Mixed-use land can change the table
- Linked deals may need combined calculations

How SDLT tax bands work when you buy property
Stamp duty land tax, often called SDLT or stamp duty, does not usually apply at one rate to your whole price. It works in bands. The result can change depending on the type of land you buy, the amount you pay, and whether any linked purchases must be considered alongside yours. Those details matter.
What this rule is about
Think of SDLT bands like income tax bands. Each slice of the price falls into its own band. You work out the tax on each slice, then add those figures together.
That sounds simple. Earlier, the difficult task is deciding which rate table applies, whether another purchase is linked to yours, and whether it must be counted alongside your purchase. That comes first.
The law calls the amount used for SDLT “chargeable consideration”. In everyday terms, this means what you give for the land, whether directly or indirectly. It can be more than the cash shown as the price.
What the official source says
HMRC’s manual says that SDLT uses a marginal rate system. In other words, each rate applies only to the part of the price within that band. HMRC also says it rounds the final tax figure down to the nearest pound.
- Use the residential table if all the land bought is residential.
- Use the non-residential or mixed-use table if any part is not residential.
- Work out tax separately for each part of the price that falls within a band.
- Add those separate amounts together.
- If purchases are linked, use their total price to identify the bands.
- For linked purchases with the same effective date, one combined return may be possible.
HMRC’s manual also says that the historic relief for buying more than one home could affect linked purchases before 1 June 2024. That date matters. The relief does not provide a general answer for later purchases.
What this means in practice
Rather than multiplying the entire price by the highest applicable rate, calculate the tax on each slice that falls within the relevant band instead. Do not do that. Only the top slice reaches the top band.
First ask what you are buying. A house with garden land may be wholly residential. When a house is bought with a shop, office, workshop, or other non-residential part, the purchase may use a different rate table instead. Check the land’s use.
- Keep the contract and any plan showing exactly what you bought.
- Check whether the deal includes land used for a business.
- List anything else you give as part of the deal.
- Ask whether you are buying other land from the same seller.
- Check whether connected people are involved in either side of those deals.
- Use the GOV.UK rates page for the table for your purchase date.
HMRC provides an online calculator. It can be useful as a check, but it only gives a sound answer if the facts entered into it are right.
How to analyse it
Start with the facts, not the calculator. A calculator cannot decide whether land is mixed-use or whether two deals form one arrangement.
- Find the effective date of the purchase.
- Work out the full amount paid or given for the land.
- Identify each part of the land included in the deal.
- Decide whether all of it is residential property.
- Check for any other purchase in the same scheme or series.
- Add linked prices before applying the bands where the linked rules apply.
- Calculate each band separately and add the results.
What actually decides whether purchases are linked? It is not just whether they complete on the same day. Instead, ask whether they form one scheme, arrangement, or series involving the same parties or people connected with them when all the facts are considered. Timing alone is not enough.
Example
Sarah buys a wholly residential home for £300,000. Using the standard residential table in the statutory copy current to 17 November 2025, the first £125,000 falls into the 0% band. The next £125,000 attracts 2%, which is £2,500. The final £50,000 attracts 5%, which is £2,500. Her total is £5,000.
Now change one fact. Imran pays £300,000 for a home and a shop in the same deal. The land includes a non-residential part. Using the standard mixed-use table in that same statutory copy, no tax falls on the first £150,000, £2,000 falls on the next £100,000 at 2%, and £2,500 falls on the final £50,000 at 5%. The total is £4,500.
These examples illustrate the method, but they cannot cover every special SDLT rule or rate that may apply when the facts of a particular purchase differ. Check the specific rules.
Why this can be difficult in practice
You might think the estate agent’s description settles the issue. It does not. The actual land and its use matter more than the label in an advert.
Linked deals cause another problem. Two contracts can look separate, yet still form part of one wider arrangement. Getting that wrong can put too much of the combined price into higher bands.
- A small business element can change the rate table.
- Separate contracts do not always mean separate SDLT calculations.
- A price split between land and something else may need a fair split.
- The final bill can depend on the purchase date.
- Historic relief rules need careful date checks.
Key takeaways
- SDLT bands apply to slices of the price, not the whole price.
- Mixed-use land can use a different SDLT table.
- Linked purchases can change the bands that apply.

Legislation
- FA 2003 section 50 — points to rules for the amount paid

- FA 2003 section 55 — how standard SDLT tax bands are applied

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
- The correct result can depend on whether land is wholly residential, partly non-residential, or part of a wider linked deal.
- Current rates and thresholds after 17 November 2025 need checking against an official current source.
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 contract and completion details
- The full price and anything else given for the land
- A clear description of every part of the land bought
- Details of any related purchases, sellers and buyers
- The effective date for each related purchase
