Stamp duty where contract rights are assigned more than once
Series of assignments: the short answer
When contract rights pass through several buyers before completion, SDLT is not based only on the final transfer document. HMRC’s examples track each assignment payment and the payment made to the original seller.
- The final buyer may be taxed on the completion payment plus the final assignment price.
- Earlier steps can be treated as separate transactions.
- A connected final assignor and buyer can trigger minimum consideration rules.

Stamp duty where contract rights are assigned more than once
Stamp duty where contract rights are assigned more than once
When one buyer passes a property contract to another before completion, HMRC’s rules can create stamp duty consequences at more than one stage. The last buyer may pay SDLT on both the money paid to the seller and the price paid for the final set of contract rights.
What this rule is about
A buyer may agree to buy land and then, rather than complete the purchase, sell their place in the contract to somebody else, who may in turn do the same before the property finally transfers. This can happen more than once.
People often call this an assignment of rights. In simple terms, the buyer sells the right to complete under the original contract. The seller still transfers the land only once, to the last person in the chain.
You might think only the person who gets the land matters for stamp duty. That is not always the end of the story.
Schedule 2A deals with these arrangements. It can treat the final step and earlier steps as separate transactions for SDLT purposes, even though the seller transfers the land only at the end.
What the official source says
HMRC’s manual gives three examples involving A, B, C and D. A owns the land. B first agrees to buy it. B then assigns their rights to C, and C assigns them to D. D completes and receives the land from A.
In the first example, the original contract price is £1 million. B pays A a £100,000 deposit. After B assigns to C for £100,000, C assigns to D for £150,000, and D then pays A £900,000 on completion under the original contract. That completes the chain.
- HMRC says D is the final buyer for the transfer to D.
- HMRC adds D’s £900,000 completion payment to D’s £150,000 payment to C.
- On those facts, HMRC gives D an SDLT amount of £1.05 million.
- HMRC treats B as the buyer in a notional transaction.
- HMRC treats C as the buyer in an additional transaction.
- For B, HMRC’s example uses the £100,000 deposit and D’s £900,000 completion payment: £1 million.
- For C, it uses C’s £100,000 payment to B and D’s £900,000 completion payment: again £1 million.
Those labels can sound abstract. Their purpose is to identify which payment belongs with which stage of the chain. HMRC uses the same £900,000 completion payment when calculating more than one transaction in the chain, even though D makes that payment only once at completion. It therefore appears more than once.
The second example changes one fact: C assigns the rights to D for £50,000, rather than £150,000. D still pays A £900,000 on completion.
- HMRC says D’s amount is then £950,000.
- That is £900,000 paid to A plus £50,000 paid to C.
- HMRC says B’s and C’s positions remain the same as in the first example.
The point is direct: the price D pays for the final assignment affects D’s SDLT figure. It does not automatically change the figures HMRC uses for the earlier steps.
What this means in practice
Follow the money, not just the final transfer document. A completion statement may show D paying A, but it may not show the earlier prices paid when the contract rights changed hands.
That missing history can produce the wrong SDLT calculation. It can also hide a connected-party issue.
- Keep the original sale contract, including any deposit terms.
- Keep every agreement assigning rights under that contract.
- Record the price paid at each stage, including a nil price.
- Check who pays the seller at completion.
- Check whether the final two parties are connected.
- Do not assume the original £1 million price is always the final buyer’s SDLT amount.
HMRC’s manual also says B and C can claim relief in its first two examples. That does not mean relief will be available in every chain. Because the source does not state the conditions, advisers should not use the examples as proof that an earlier buyer pays no SDLT.
How to analyse it
Start with the documents in their real order. Then map each payment to the person who made it and the person who received it. This matters more than the names used in an estate-agent email or a side agreement.
- Identify the original seller and the first buyer under the sale contract.
- Find the full price under that original contract.
- List the deposit and who paid it.
- List each assignment before the land is transferred.
- Record the price for each assignment, including £0.
- Identify the final buyer who receives the land.
- Record the sum paid to the seller on completion.
- Ask whether the final assignor and final buyer are connected.
- Test whether the minimum consideration rules may apply.
What actually decides the final buyer’s figure? In HMRC’s examples, it is the completion payment plus the price for the final assignment. That answer can change where the final parties are connected.
Example
Take HMRC’s connected-party example. A agrees to sell land to B for £1 million, and B pays A a £100,000 deposit. B sells the contract rights to C for £50,000. C then gives those rights to D for nothing, and D pays A £900,000 on completion.
At first sight, D has paid £900,000: nothing to C and £900,000 to A. HMRC says that is not the final answer because C and D are connected.
HMRC applies a minimum figure of £950,000. The first minimum figure is C’s £50,000 payment to B plus D’s £900,000 completion payment. The second is also £950,000, made up of £50,000 given by C and £900,000 given by D.
So HMRC’s example charges D by reference to £950,000, not £900,000. A gift of the final contract rights does not necessarily reduce the amount used for SDLT.
Why this can be difficult in practice
The figures may look easy once they are laid out. Real arrangements rarely arrive in that neat form. Parties may route payments through solicitors, hold them as deposits, set them off against another debt, or describe them poorly in the paperwork while the contract rights move through the chain. The paperwork may not make this clear.
Connection is another problem. A low price between independent parties may be commercial. The same low price between connected parties can bring in the minimum amount rules described by HMRC.
- A payment for rights may be hidden within a wider settlement agreement.
- A deposit may be paid by one party but later funded by another.
- A chain may involve part of the land or only some contract rights.
- A nil-price assignment does not end the enquiry where parties are connected.
- Relief for an earlier step needs its own conditions checked.
- The timing of the assignments and completion can affect which rules apply.
When your solicitor has received only the final transfer, they can miss the earlier chain of assignments and payments that explains how the SDLT position arose. That is the risk. Your solicitor needs the full chain of contracts and payments before they can work out the SDLT position properly. Nothing less will do.
Key takeaways
- The final buyer’s SDLT figure can include the final assignment price and the completion payment.
- Earlier assignments can create separate notional or additional transactions.
- Connected parties can trigger a minimum SDLT amount, even where final rights are given away.

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 source does not give the transaction dates, so it does not show whether commencement or transitional rules could affect a particular transaction.
- The source does not explain the conditions for relief for the earlier notional and additional transactions.
- Whether two people or businesses are connected can require detailed facts about ownership, control and family relationships.
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 sale contract and its agreed price
- proof of every deposit and completion payment
- each assignment agreement and the price paid for it
- the completion statement showing who paid the seller
- evidence of any connection between parties in the final assignment
- the dates when contracts, assignments and completion occurred
