Stamp duty on an option to buy property or a right of first refusal
Options and SDLT
A binding option to buy land or a right of first refusal can be a separate SDLT transaction, even before the property is bought.
- Check whether the agreement creates an enforceable land right.
- Check whether the later purchase is linked to the earlier grant.
- Keep records of fees, dates, parties and the underlying land.

Stamp duty on an option to buy property or a right of first refusal
Stamp duty on an option to buy property or a right of first refusal
Stamp duty may arise before you buy a property. A binding option to buy land, or a right of first refusal that restricts how the owner may deal with the land, can itself be an SDLT transaction. It may be taxable separately. A later property purchase is another transaction, and the two may be linked.
What this rule is about
An option gives a binding purchase right. It expires on a stated deadline. Subject to the agreement’s terms, you can require the owner to sell. You may pay a separate fee for it.
A right of pre-emption is usually called a right of first refusal. It does not necessarily let you force a sale. Instead, it stops or limits the owner from selling to somebody else without first dealing with you.
These rights can look like an early stage of a property purchase. For SDLT, though, they may matter in their own right. A qualifying right’s grant and the later purchase are distinct land transactions.
That distinction can affect both the tax due and whether a return is needed.
What the official source says
HMRC’s manual says that options and rights of first refusal are interests in land, but not major interests. A major interest is broadly a freehold or leasehold estate. As a result, the special return rules for a non-major land right apply to the grant.
For an option, the legislation requires the owner to be bound to enter into a land transaction. It also covers an option where the owner can meet that obligation in another way, such as by paying money instead.
- A qualifying option grant is a separate SDLT transaction.
- A qualifying right of first refusal grant is also a separate SDLT transaction.
- Using either right to buy the land creates a later, separate transaction.
- The grant date is the date you receive the right. First use does not set it.
- HMRC: reservation deposits alone create no rights.
- The right follows the type of land beneath it: residential, mixed, or non-residential.
HMRC’s manual is guidance, not the law itself. Although its view on reservation deposits and similar payments is useful when assessing whether a right exists, the agreement must still be read carefully. Its label is not decisive. A document called a reservation agreement may give stronger rights than its name suggests.
What this means in practice
Start by looking at the fee for the right. SDLT may arise on the option price. That is the amount paid to obtain the option or right. Applicable rates follow the type of land covered by it.
Do not assume that the earlier fee disappears for SDLT if you later buy the property. Where the grant and purchase are linked, the calculation uses the option fee and later price together. Tax is then apportioned between the two transactions.
- For the grant, work out its share of tax by reference to the total of the option fee and purchase price, using rates at the grant date.
- When calculating what remains due for the grant, take account of SDLT already paid on the option fee, even where the grant and later purchase are dealt with as linked transactions. Do not leave it out.
- For the later purchase, work out its share using the same combined total, but rates at the date of that purchase.
- Keep the option agreement and proof of every payment.
- Check whether the land includes a home, business land, or both.
This can produce a result that feels odd. There are two transactions, and the rates may have changed between them. Dates therefore matter as much as the figures.
How to analyse it
Begin with the document, not its heading. Ask what legal rights the owner gave you, what the owner must do if you choose to act, and whether the agreement allows another form of settlement. Read the terms closely.
- Is there a binding option requiring the owner to sell, or allowing another form of settlement?
- Is there a right that prevents or restricts a sale to somebody else?
- Was the payment only a reservation deposit, or did it buy a legally enforceable land right?
- What land does the agreement cover?
- Is that land residential, non-residential, or mixed?
- When was the right granted, assigned, and used?
- Was the right sold, changed, surrendered, or transferred before it was used?
- Do the grant and later purchase form one scheme, arrangement or series involving the same or connected parties, rather than merely two deals that have some connection with each other? That distinction matters.
- What was paid for the right, and what was paid for the property?
- Was SDLT paid or a return made when the right was granted?
The linked-transactions test is central. One scheme involving connected parties is required. It must involve the same seller and buyer, or people connected with them. A connection between the two deals is not enough by itself.
If a later linked transaction makes the earlier grant notifiable, a return for that grant may be due within 14 days of the later transaction, while a later transaction that creates tax or extra tax on the earlier grant may require a further return within 30 days.
The later purchase can have its own return requirement as well.
Example
Priya pays £10,000 for an option over a plot of land. The agreement binds the owner to sell the plot to her if she uses the option. Six months later, Priya uses it and pays £300,000 for the plot.
There are two SDLT transactions: Priya’s purchase of the option, and her later purchase of the plot. If they are linked, the SDLT calculation considers the £310,000 total. It then allocates tax between the £10,000 option fee and the £300,000 paid on purchase.
Rates applicable when Priya received the option apply to its calculation. Rates applicable when she bought the plot apply to the later purchase. Any SDLT already paid on the option is taken into account.
Now change one fact. Priya assigns the option to Omar. Omar is unconnected to Priya or the owner. Omar later uses it.
HMRC says that, where Omar is unconnected to Priya or the owner and later uses the assigned option, the later purchase can be a situation not linked to the original grant. The agreements and relationships need close checking.
Why this can be difficult in practice
People often get this wrong: a payment made before a sale is not automatically outside SDLT. Calling it a holding deposit, reservation fee or option fee does not settle the answer.
Equally, paying money does not automatically create an option. HMRC’s manual says a reservation deposit or similar payment is not one on its own. The real issue is whether the contract gives you an enforceable right over the land or merely holds it while talks continue.
- A short agreement may hide a binding right in its detailed terms.
- The owner may have a choice between selling and making a payment, yet the option can still fall within the rule.
- A transfer of the option can itself need consideration because a sale, change or surrender of a land right may be taxable.
- Residential status follows the underlying land, not what the parties call the option.
- An option over a home and business land may raise mixed-property questions.
- Linked status can change the amount due and trigger a later filing duty.
If you only remember one thing, make it this: check the first agreement when the later purchase happens. The original fee, dates, parties and rights may all affect the SDLT result.
Key takeaways
- A binding option or right of first refusal can trigger SDLT before a property purchase.
- Using the right to buy creates a separate transaction.
- Linked transactions can change the tax calculation and return position.

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 label given to a payment does not settle whether it creates a binding option or merely reserves a property. The written agreement and the parties’ rights matter.
- Whether the grant and later purchase are linked is fact-sensitive, especially after an option has been assigned.
- This page does not state current SDLT rates. The rates in force on each relevant date 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 signed option, pre-emption or reservation agreement
- The amount paid for the right and the later property price
- Dates when the right was granted, assigned and used
- Details of the land covered by the right
- Evidence of the parties’ relationship and any wider arrangement
- Any SDLT return and tax paid when the right was granted
