LTT relief when a council buys land for another developer
A local authority may not have to pay Land Transaction Tax, often called stamp duty, when it buys land under its own compulsory purchase order. This can apply where someone else will develop the land.
What this rule is about
When a local authority buys land under a compulsory purchase order that it made, and a separate developer is intended to develop that land, the acquisition is the first step. It may qualify for relief.
Later, the same land may be sold again. Only the authority’s first purchase receives the relief. It does not automatically pass with the land to the developer.
What the official source says
Where a compulsory purchase helps development, legislation gives full LTT relief, and Welsh Revenue Authority guidance explains how the conditions are applied when deciding whether relief is available. Those conditions matter.
- The body that made the compulsory purchase order must be the buyer.
- In most cases, this buyer will be the local planning authority.
- To help another person develop the land, the order must have been made.
- That other person must be the developer.
- Where the local authority will develop the land itself, this relief does not apply.
- Even if the owner agrees to sell rather than being forced to transfer the land, the purchase can still qualify.
What this means in practice
On its own, a compulsory purchase order is not enough.
To determine whether the authority’s first purchase can qualify for relief, ask why the order was made, who made it, and who will carry out the development. Those facts decide qualification.
When the authority later transfers the land to the developer, that is a new land transaction. Under the normal LTT rules, the official source says that transfer is dealt with separately.
- Keep the compulsory purchase order with the tax records.
- Check that the authority named as buyer made that order.
- Keep records that show the planned developer is a separate person.
- Do not assume the developer’s later purchase has the same relief.
How to analyse it
Check the facts in order. A label such as “regeneration project” will not answer the question by itself.
- Is this a purchase of a legal interest in land?
- Did the buyer make a compulsory purchase order?
- Was the order made to help development?
- Will someone other than the local authority carry out that development?
- Was the land bought under that order, even if the owner agreed the sale?
- Is the transaction being considered the authority’s first purchase, rather than a later transfer?
Example
To assemble land for a private company that will build shops and flats, a council makes a compulsory purchase order, under which one owner agrees to sell. It remains under the order.
Because the council made the order and another person will develop the land, the council’s purchase can meet the relief conditions.
Later, the council transfers the land to the company. That later transfer is considered separately under the normal LTT rules.
Why this can be difficult in practice
People often assume that any council purchase under a compulsory purchase order is free of LTT. The rule is not that broad.
Usually, who is planned to develop the land is the key fact.
- A project may involve both the authority and a private developer.
- Plans can change between making the order and buying the land.
- The documents must show why the order was made.
- An agreed sale can qualify, but it must still be under the buyer’s order.
Key takeaways
- An authority must have made the compulsory purchase order.
- Someone else must be developing the land.
- A later transfer to that developer is not covered by this relief.
