SDLT relief for land outside a Freeport or Investment Zone tax site
SDLT relief for land outside a Freeport or Investment Zone tax site
Buying land partly outside a tax site does not automatically block stamp duty land tax relief. But HMRC says relief for that outside land is only possible if the whole deal passes the test for 100% relief.
What this rule is about
A special tax site can be part of a Freeport or Investment Zone. The relief is aimed at qualifying land in that site. Problems arise when one purchase includes land both inside and outside the boundary.
That boundary matters. A single contract does not turn all the land into site land.
What the official source says
HMRC’s manual says relief for the amount paid that relates to land outside the special tax site is only available if the deal meets the 100% relief test. HMRC’s manual is guidance, not law.
- Check whether the purchase includes any land outside the site.
- Do not assume nearby land is inside the boundary.
- Apply the separate test for 100% relief to the whole deal.
- Only then consider relief for the outside land.
What this means in practice
Part of the land may be within the site, while an access strip, yard or extra field is outside it. HMRC’s view is that the outside part cannot receive relief just because it was bought in the same deal.
- Keep a clear site plan with the purchase papers.
- Match the plan to the official site boundary.
- Check what land the contract actually includes.
- Keep evidence for the intended use of the land.
How to analyse it
Start with the map, not the property description. Then work through the relief test for the deal as a whole.
- Identify all land being bought.
- Mark the land inside and outside the tax site.
- Check whether the inside land is qualifying land.
- Apply the 100% relief test.
- Consider how the price relates to each part of the land.
Example
Ava buys a workshop plot inside a special tax site with a small access strip outside it. The strip is part of the same purchase. HMRC’s guidance says its position depends on whether Ava’s whole deal meets the 100% relief test. Site location alone is not enough.
Why this can be difficult in practice
Maps, title plans and contract plans may not show the same boundary with the same detail. A small area can matter. The supplied source also does not explain the full 100% test or how to split the amount paid between the two areas.
- Land described as ancillary may still sit outside the site.
- A plan may be unclear at the boundary.
- The 100% test needs checking separately.
Key takeaways
- Outside land is not relieved automatically.
- HMRC requires the 100% relief test for that land.
- Check the boundary and the full deal.
Technical analysis
For advisers, and for anyone who wants to check the law behind this page. You do not need this section to understand the guidance above.
Legislation

- FA 2003 Schedule 6C para 2 — defines qualifying land for the relief
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 supplied material does not explain the full 100% relief test or how an amount paid is allocated between land inside and outside a site.
- The supplied statutory text is current only to 17 November 2025. The law for a later transaction must be checked against current primary legislation.
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.
- A plan showing every part of the land being bought.
- Evidence of which land lies within the special tax site on the effective date.
- The contract and price allocation, if any.
- Evidence relevant to the separate 100% relief test.
