When planning obligations relief from LTT is available
A developer may not have to pay Land Transaction Tax (LTT), the Welsh tax that replaced stamp duty land tax, when land passes to a public body under a planning obligation. But every condition must be met. Missing one can mean the relief is unavailable.
What this rule is about
Planning permission can require a developer to provide land for a road, school, health service or another public purpose. A formal planning obligation may set out that requirement.
The developer may then transfer the land to the public body responsible for providing the relevant service. In narrow cases, the law gives LTT relief for that transfer. It is not a general exemption for giving land to a council.
Ask whether the transfer was genuinely made to meet an enforceable planning obligation.
What the official source says
The legislation sets three conditions. According to the official guidance, all three must be satisfied for relief to apply. This is an all-or-nothing test.
- For relief to be available, the seller must be bound, at the time of the transfer, by a planning obligation or formal amendment that is legally enforceable against that seller.
- It must already be in place before the transfer.
- It may be enforceable through a court or by another legal method.
- No one needs to have started enforcement action. What matters is that enforcement was possible.
- For relief, the buyer must be a public body.
- For the LTT transaction, the relevant date must fall within five years of the obligation or its latest modification, as appropriate.
If no enforceable obligation binds the seller, the seller has no legal duty to perform. Relief cannot then be claimed.
The Act gives examples of public bodies. They include county or county borough councils and specified Welsh NHS bodies. Welsh Ministers can also add bodies through regulations.
What this means in practice
Start with the paperwork, not the reason for the transfer. A transfer may plainly help a local community, yet still fail this relief if the legal documents do not create an enforceable duty.
This is the part people can get wrong. They may focus on the planning permission and overlook the separate planning obligation.
- Check that the seller signed or was otherwise bound by the obligation.
- Check whether the document was changed after it was first made.
- Confirm exactly who is receiving the land.
- Do not assume every public service organisation is a public body for this relief.
- Work out the date that counts for LTT before relying on the five-year limit.
A transfer can still be required by planning arrangements but fall outside the relief. For example, it may happen too late. The timing rule has no extra allowance in the official source.
How to analyse it
Work through the conditions in order. That makes it easier to spot the document or date that decides the answer.
- Identify the planning obligation that the transfer is said to meet.
- Read its terms and check that it was enforceable against the seller before the transfer.
- Find every formal modification, including the most recent one.
- Identify the buyer and compare it with the statutory public-body list.
- Work out the LTT effective date for the transfer.
- Count five years from the latest date when the obligation was made or modified.
- Check whether the transfer is made to comply with that obligation, rather than for a separate commercial reason, after considering the documents and the purpose of the transaction. That purpose matters.
Keep copies of the obligation, any changes and documents confirming the buyer’s status. Those records explain why relief was claimed.
Example
Here is the example used in the official guidance. A planning obligation was made on 1 March 2020. It was modified on 20 September 2022, then modified again on 25 June 2023. If land later passes from the developer to a public body to comply with it, the transfer must take place by 24 June 2028. That is the final day within five years beginning on 25 June 2023.
A transfer on 25 June 2028 falls outside that five-year period. The earlier dates do not extend the deadline.
Why this can be difficult in practice
Similar terms often describe quite different documents. A planning condition, a contract and a planning obligation can each affect a development. Only the statutory type of planning obligation can support this relief.
Changes can also matter more than expected. A small formal modification may alter the date from which the five years run.
- Describing a document as a planning obligation does not establish that it was properly made or is enforceable.
- Even a transfer to a public body cannot qualify without an enforceable obligation binding the seller.
- An obligation that was never enforced can still qualify if it was capable of enforcement.
- The latest formal modification matters for the time limit.
- The relief may be unavailable if the transfer happens after the five-year period ends.
Key takeaways
- All three conditions must be met for planning obligations relief.
- The seller must be subject to an enforceable planning obligation.
- The buyer must be a public body and the transfer must be in time.

Where this is not settled
- Whether a particular document is an enforceable planning obligation can depend on its wording, form and legal effect.
- Whether a body is a public body depends on the statutory list and any regulations made by Welsh Ministers.
