Guidance on Stamp Duty Land Tax Relief for Planning Obligations Compliance

SDLT relief for land transfers required by planning obligations

This is a narrow SDLT relief for land transactions carried out to comply with a qualifying planning obligation, or a formal change to one. It is mainly intended to prevent certain public authorities from paying SDLT where planning law requires the transfer, and it does not apply simply because a transaction is connected with a development.

• The transaction must be a land transaction undertaken to comply with a qualifying planning obligation or a formal modification of one.
• For England, this includes obligations under section 106 and section 299A of the Town and Country Planning Act 1990, and modifications under section 106A(1).
• For Northern Ireland, this includes planning agreements under article 40 of the Planning (Northern Ireland) Order 1991, and modifications under article 40A(1).
• Relief is not automatic for all planning-related transfers; there must be a direct link between the legal obligation and the land transaction.
• The purchaser must fall within the class of public authority covered by the legislation, and all statutory conditions must be met.
• In practice, it is important to check the wording of the planning obligation, any formal modification, the transfer document, and the purchaser’s status.

SDLT relief for land transfers made to comply with planning obligations

This page explains a narrow Stamp Duty Land Tax relief that can apply where land is transferred in order to comply with a planning obligation, or a formal modification of one. The point of the relief is to prevent certain public authorities from having to pay SDLT when a land transaction is carried out because planning law requires it.

What this rule is about

Some developments are allowed to proceed only if the parties enter into a planning obligation. In practice, that can require land to be transferred, granted, or otherwise dealt with in a particular way. The SDLT rules recognise that, in some cases, a land transaction happens not as an ordinary commercial acquisition but because planning law requires it.

The source material says that where a land transaction is undertaken to comply with a planning obligation, or with a modification of a planning obligation, the purchaser may claim SDLT relief if the statutory conditions are met. HMRC also explains the policy behind the relief: it is intended to spare certain classes of public authority from SDLT in those circumstances.

This means the relief is not a general exemption for any transaction connected with development or planning. The key issue is whether the transaction is genuinely undertaken to comply with the relevant planning obligation or modification, and whether the claimant falls within the class that the legislation is designed to protect.

What the official source says

The official material identifies two core elements.

First, there must be a land transaction undertaken to comply with:

• a planning obligation, or
• a modification of a planning obligation.

Secondly, the purchaser may claim relief if the required conditions are fulfilled.

The source then defines what counts as a planning obligation and what counts as a modification for the jurisdictions it covers:

• For England, a planning obligation includes one within section 106 of the Town and Country Planning Act 1990, entered into in accordance with that section, and one defined by section 299A of that Act, entered into in accordance with that section.
• For Northern Ireland, it includes a planning agreement within article 40 of the Planning (Northern Ireland) Order 1991, entered into in accordance with that article.
• For England, a modification includes one mentioned in section 106A(1) of the Town and Country Planning Act 1990.
• For Northern Ireland, a modification includes one mentioned in article 40A(1) of the Planning (Northern Ireland) Order 1991.

The source does not set out all of the qualifying conditions in this extract. It only states that relief is available if certain conditions are fulfilled.

What this means in practice

The practical question is not simply whether a transaction has something to do with planning. Many land transfers happen in the context of development, but that alone does not bring them within this relief.

The transaction must be undertaken to comply with the planning obligation or its formal modification. That usually points to a direct link between:

• the legal requirement created by the planning obligation, and
• the land transaction for which relief is claimed.

For example, if a developer is required under a section 106 obligation to transfer a parcel of land to a qualifying public authority for a planning purpose, the transfer may be the kind of transaction this relief is aimed at. By contrast, if land is acquired as part of wider commercial negotiations around a development, but not because the planning obligation itself requires that acquisition, the relief may be much harder to establish.

The source also makes clear that the relief is aimed at defined classes of public authorities. That matters because the purchaser claiming relief must be within the relevant class. A transaction carried out under a planning obligation will not automatically qualify if the purchaser is not the kind of body the legislation covers.

How to analyse it

A sensible way to analyse this relief is to work through the following questions.

• Is there a land transaction for SDLT purposes?
• Is there a qualifying planning obligation or a qualifying modification of one, as defined by the relevant planning legislation?
• Was the transaction undertaken to comply with that obligation or modification, rather than merely being connected with the same development?
• Who is the purchaser for SDLT purposes, and is that purchaser within the class the relief is intended to cover?
• Are the statutory conditions for the relief met in full?

Documents will often matter. In practice, you would usually want to review:

• the planning obligation itself, including the exact drafting of the obligation to transfer or grant rights over land,
• any formal deed or instrument modifying that obligation,
• the transfer or other land transaction document, and
• the identity and status of the purchaser.

The closer the wording of the land transaction matches the legal requirement in the planning obligation, the easier it is to show that the transaction was undertaken to comply with it.

Example

A developer enters into a section 106 agreement in England as part of a planning permission. The agreement requires a specific area of land to be transferred to a local authority for use connected with the development. The transfer is later completed exactly as required by the section 106 agreement. If the purchaser is a public authority within the class covered by the relief, and the other statutory conditions are met, the purchaser may be able to claim SDLT relief on that transfer.

By contrast, if the developer separately sells neighbouring land to the same authority as part of broader commercial arrangements, and that sale is not required by the section 106 agreement or a formal modification of it, this relief would not obviously apply just because the transaction sits in the same development context.

Why this can be difficult in practice

The main difficulty is causation and scope. A transaction may be linked to planning obligations in a broad sense without actually being undertaken to comply with one. The official material in this extract does not provide a detailed test for drawing that line.

Another difficulty is that the extract refers to relief for defined classes of public authorities, but does not list those classes or all of the qualifying conditions. So it would be unsafe to assume that every authority involved in a planning-related transfer can claim relief.

There can also be drafting issues. Planning obligations often include a mixture of strict legal requirements, practical arrangements, and later variations. Relief appears to depend on the transaction being tied to a qualifying obligation or a qualifying formal modification. Informal changes in approach, or transactions that are commercially convenient but not legally required by the obligation, may create uncertainty.

Key takeaways

• This relief is aimed at land transactions carried out to comply with a qualifying planning obligation or a formal modification of one.
• It is not a general SDLT exemption for all planning-related or development-related transactions.
• The exact wording of the planning obligation, the nature of the transaction, and the status of the purchaser are likely to be central to whether relief can be claimed.
