Stamp duty where separate plots are sold on one by one
Separate plots can mean separate SDLT transactions
HMRC says that land sold under one contract can be treated as separate plot transactions where the contract genuinely allows each plot to complete separately.
- Each plot may have its own completion date.
- HMRC says full subsale relief may be claimed for each qualifying plot.
- Artificially splitting one deal may not achieve that result.

Stamp duty where separate plots are sold on one by one
If you agree to buy several plots of land, then sell each plot on before you complete, stamp duty may need to be looked at plot by plot. HMRC says this can allow relief for the middle buyer. But the contract must really allow separate completions. Simply splitting one deal on paper may not work.
What this rule is about
Sometimes a buyer agrees to buy several plots. Before the purchase completes, that buyer finds separate people to buy the plots.
This is often called a subsale. It means one person sits in the middle: they have agreed to buy from the original seller, but they also have an agreement to sell on.
The key question: separate deals or one disguise? That distinction can decide the stamp duty result.
What the official source says
HMRC’s manual gives an example where one contract covers three plots, but allows the buyer to complete each plot separately before a final date. The buyer then agrees to sell each plot to a different person.
HMRC treats it as three separate contracts. Each plot therefore has its own SDLT transaction and its own completion date.
- Plot 1 completes through both sales.
- Plot 2 completes later through the same chain.
- Plot 3 completes later still through its own chain.
- HMRC says the middle buyer has three separate purchases, one for each plot.
- HMRC says those purchases are linked because they arise from the same overall arrangement.
- HMRC says each sell-on deal can be a separate qualifying subsale.
- HMRC allows full relief per plot, conditionally.
That is HMRC’s published view. The legislation remains the law, and the facts of the contract matter.
What this means in practice
For the middle buyer, the result can be important. If the arrangement fits the rules, the middle buyer may claim relief rather than paying SDLT on each plot they briefly agreed to buy.
The final buyers do not inherit that relief. HMRC says normal SDLT rules apply to each completed purchase.
- Keep each plot clearly identified in the contract and plans.
- Record the separate completion date for every plot.
- Keep the original agreement and each sell-on agreement together.
- Do not assume that a single overall price prevents separate plot treatment.
- Remember that linked deals can still matter when SDLT is worked out.
You might think three different completion days automatically create three separate deals. They do not. The right to complete each plot separately must be part of the real arrangement.
How to analyse it
Start with the original contract, not later-document labels. Ask what it actually requires and what each party was entitled to do.
- Does the original contract cover several identifiable plots?
- Does it allow a separate completion for each plot before the final completion date?
- Did the middle buyer make a separate agreement to sell on each plot?
- Did each chain complete together for that plot?
- Is there a separate effective date for each plot?
- Do the sell-on agreements meet the conditions for subsale relief?
- Are the arrangements commercially real, rather than an artificial split?
- Is this instead one plot with one final completion and staged payments or occupation?
- Has the middle buyer sold only part of land covered by one original contract?
The last two questions matter most. HMRC says they are different situations, with different treatment under the subsale rules.
Example
Amir agrees to buy three plots from Rosa for £10 million. The contract names Plot 1, Plot 2 and Plot 3. It allows Amir to complete each plot separately before the agreed final date.
Amir agrees to sell Plot 1 to Beth for £5 million, Plot 2 to Callum for £4 million, and Plot 3 to Dina for £1 million. On Day 1, Rosa sells Plot 1 to Amir. Amir then sells it to Beth. Plot 2 completes on Day 2. Plot 3 completes on Day 3.
HMRC’s manual treats this as three separate original contracts and three separate sell-on deals. On that view, Amir can claim full relief for each plot if the statutory conditions are met and nothing else blocks relief.
Why this can be difficult in practice
The paperwork may conceal a single deal. HMRC specifically warns that its approach is unlikely to apply where what is really one land deal has been split in a contrived way to reduce SDLT.
This is the part people get wrong: separate plans, separate prices and separate buyers may support the answer, but they do not settle it alone. The original contract and the commercial reality still matter.
- A contract may describe plots but require one final completion over the whole site.
- Staged occupation or payment for one plot is not the same as separate plot completions.
- Selling part of one plot is not automatically a separate original contract.
- Relief is not automatic merely because the sales complete on the same day.
- Different completion dates do not cure an arrangement that was artificial from the start.
- The relevant law must be checked against the effective date of each plot transaction.
Key takeaways
- Separate completion rights can make each plot a separate SDLT transaction.
- HMRC says full subsale relief may be available for each genuine plot deal.
- One deal split artificially, or one plot completed only at the end, may have a different result.

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 land is genuinely made up of separately completable plots depends on the contract and the real commercial arrangements.
- HMRC’s manual does not give a full test for deciding when a split is contrived.
- The source does not state the transaction date, so the legislation in force on the relevant effective dates must be checked.
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 original contract and any clauses allowing each plot to complete separately.
- Plans identifying each plot.
- The agreements under which each plot is sold on.
- Completion statements and dates for every sale.
- Evidence of the commercial reason for the plot structure.
