LTT on an option to buy land: why two returns may be needed
Paying for an option to buy land in Wales can require you to file an LTT return before you buy the land itself. That can come as a surprise. In the Welsh Revenue Authority’s example, the buyer had to file once for the option and then file two returns after using it.
What this rule is about
An option gives you the right to buy land later, usually on agreed terms, while you seek planning permission or meet another condition before committing to ownership. You do not own the land yet. It can be useful where you need planning permission first. You pay to keep that right open.
For Land Transaction Tax, or LTT, the law treats obtaining the option as a separate land deal from buying the land after you use it, even though both steps concern the same land. That distinction matters.
So there may be two important dates. You obtain the option on one date. You complete the later purchase on the other.
What the official source says
WRA’s example involves two companies and land. U Ltd owns the land. W Ltd wants to buy it, but only if it can obtain planning permission.
- On 1 March 2020, W Ltd pays U Ltd £200,000 for an option.
- The option lets W Ltd buy the land within three years.
- The agreed later price is £2,300,000.
- W Ltd must send an LTT return for the option to WRA by 31 March 2020.
Planning permission arrives on 1 September 2022. W Ltd uses the option on 1 October 2022 and pays the extra £2,300,000.
WRA links the two deals. W Ltd must file a return for the later purchase by 31 October 2022. It must also file a further return for the earlier option by that same date.
What this means in practice
You might think that the first payment simply serves as a deposit towards a future purchase, because it will form part of the wider arrangement for acquiring the land. In this example, it does not. It is payment for a separate right over the land.
That is the part people get wrong. An option can create a filing job even where the hoped-for purchase never happens.
- Record the date you obtain the option.
- Do not wait for planning permission before checking the LTT position.
- Keep the option payment separate from the later land price in your records.
- When you exercise the option, revisit the return for the option while also filing for the purchase, so that you address both transactions and their connected deadlines. Check both filings.
Linked transactions can change the way the law calculates LTT, because it considers the total amount paid across linked deals before allocating the resulting amount between them. The official example does not give an LTT calculation, so it does not establish a tax figure.
How to analyse it
Start with the documents, not the label used by the parties. Calling a payment a reservation fee does not settle what rights it gives you.
- Is there a binding option over land in Wales?
- When did you obtain that option?
- What did you pay for it?
- Was there a later purchase under the option?
- Do the option and purchase form one arrangement between the same parties, or connected parties?
- What was the effective date of each deal?
- Does the later linked deal require a further return for the earlier one?
For the return deadline, the usual rule gives you 30 days starting on the day after the effective date, regardless of whether the transaction concerns an option or a later purchase. The dates are 31 March and 31 October. They cover the option and later purchase.
Example
Here is the official example in plain terms. W Ltd pays £200,000 on 1 March 2020 to secure a three-year right to buy U Ltd’s land for a further £2,300,000. It must file an LTT return for that first deal by 31 March.
Seven months before the option ends, W Ltd gets planning permission. It completes its land purchase on 1 October 2022 and pays the £2,300,000 balance. Because WRA links the option and purchase, W Ltd files for the purchase by 31 October. It also sends a further return for the option by then.
Why this can be difficult in practice
The dates are easy to miss because an option may sit unused for years. Planning, finance and conveyancing can take centre stage. The earlier tax filing can then be forgotten.
Not every later land purchase is automatically linked to an earlier option. The question is whether the deals form one scheme, arrangement or series between the relevant parties. The paperwork and the commercial facts matter.
- Missing the filing duty when you obtain the option.
- Assuming tax is considered only when the land changes hands.
- Overlooking the need for a further return after a linked purchase.
- Trying to calculate a tax amount from this example alone.
There is a simple lesson: an option is not just a promise about a future purchase. For LTT, it can be a taxable step in its own right.
Key takeaways
- An option and the later land purchase are separate LTT events.
- WRA’s example treats the option and purchase as linked.
- A later linked purchase can mean filing another return for the option.

Official guidance
The pages below are the Welsh Revenue Authority’s guidance. Guidance is not law. It sets out how the Welsh Revenue Authority 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. the Welsh Revenue Authority can also change or withdraw guidance, and it may not cover your facts.
Where this is not settled
- The example shows that these particular arrangements were linked. It does not mean every option and later purchase will be linked.
- The source does not give enough information to calculate the LTT due.
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 agreement and its date.
- Evidence of the option payment and later purchase payment.
- The completion date when the option is exercised.
- Documents showing the parties and the planned land purchase.
