Freeport and Investment Zone stamp duty relief: the three-year control period

Freeport and Investment Zone stamp duty relief: the three-year control period
If you claimed stamp duty land tax relief for land in a Freeport or Investment Zone, its use still matters after you buy. Qualifying use must continue throughout control period. Otherwise, all claimed relief can be lost. It is not limited to the part whose use changed.
What this rule is about
This relief covers special tax site land. That is the statutory term used for relevant Freeport and Investment Zone areas.
When you buy, intended use partly determines the relief. What happens next is then checked by the law. Required commercial use is what the relief supports.
From the effective date of the purchase, the key period normally runs for three years. In most straightforward purchases, that will be the completion date. That date needs checking if the purchase was structured differently.
What the official source says
HMRC’s manual says relief is withdrawn if the buyer stops using qualifying land exclusively in a qualifying manner during the control period. Control period and consequences are set by the legislation.
- The period starts on the effective date of the transaction.
- It ends three years after that date, unless it ends sooner.
- It ends sooner if there is a complete disposal of the qualifying land.
- Withdrawal is triggered by a failure to use the qualifying land exclusively in a qualifying manner.
- If relief is withdrawn, a further SDLT return is required.
- The further return and payment are due within 30 days after qualifying use ended.
- The tax due is the full relief originally claimed.
What matters is not simply whether one small area changed. According to the source, the whole relief is withdrawn for tax purposes.
What this means in practice
If qualifying use stops before the control period ends, even where the change concerns only a small area and regardless of that area’s size or value, an earlier tax saving can become a later tax bill. That can be costly. Do not assume it will match the size or value of the changed area.
That distinction sounds harsh. It can decide a large amount of tax.
- Keep the original return and the calculation showing the relief claimed.
- Keep site plans that identify the land covered by the claim.
- Record how each part of that land is actually used.
- Note the exact date when any use changes.
- Check whether the change happened before the control period ended.
- Calculate the full amount of relief claimed, rather than only the tax linked to one plot.
- Prepare for a further return and payment if the withdrawal condition is met.
If your plans changed after completion, check this first: did the land stop being used only in a qualifying way before the control period ended?
How to analyse it
Begin with the dates, then consider the land and its use. Do not start with the size of the area that changed. That is not how HMRC’s example approaches the result.
- Find the effective date of the purchase.
- Identify the qualifying land on the original claim.
- Check whether the land was in a special tax site on that date.
- Check the intended qualifying use at that point.
- Establish the actual use throughout the control period.
- Identify the first date when qualifying use ended, if it did.
- Check whether there had already been a complete disposal of the qualifying land.
- Calculate the relief originally claimed and tax already paid.
- Apply the 30-day deadline from the date qualifying use ended.
Why focus on the first date? The official source uses that date for the further return and payment deadline.
Example
HMRC gives an example of a buyer who pays £400,000 for 40 acres of mixed land in a special tax site. The buyer intends to use 30 acres in a qualifying manner, so the SDLT charge is reduced to reflect that relief. Two years later, one acre changes use. The buyer stops using one acre of those 30 acres in a qualifying manner.
HMRC says the result is not a tax charge only for that one acre. A further return is due within 30 days of the change. After tax already paid is deducted, the buyer must pay the SDLT due for the whole 40-acre purchase. In effect, the full relief originally claimed is lost.
Why this can be difficult in practice
Use can change gradually. A site may also have different activities on different areas. Where land was bought for development, rental income or a business operation, and use changes gradually or differs across areas, good records become particularly important. Keep them current.
You might think a later change is harmless because the original intention was genuine. It may not be. Continuing use conditions are the reason for the control period.
- Plans and actual use may not match after a project changes course.
- It may be unclear exactly when the qualifying use stopped.
- Mixed land needs a clear plan showing the relevant areas.
- A partial change can lead to loss of the full relief claimed.
- A sale of part of the land may not be a complete disposal.
- Being in a named local scheme does not alone prove special tax site status.
Although HMRC’s manual is useful evidence of its approach, it is not the law itself. For the legal test, the starting point is Schedule 6C to the Finance Act 2003.
Key takeaways
- The usual control period is three years from the effective date.
- A change of qualifying use can withdraw all the relief claimed.
- Withdrawal brings a further return and payment deadline of 30 days.

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 every fact that may show when a change of use occurred.
- The manual identifies complete disposal as ending the control period. It does not say that selling only part of the land ends it.
- The bundled legislation is current only to 17 November 2025. The applicable law and site designation should be checked for transactions or changes after that date.
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 effective date of the purchase
- The land plan and the part for which relief was claimed
- Evidence of the intended and actual use of each part of the land
- The date on which any qualifying use ended
- Details of any complete disposal of the qualifying land
- The original SDLT return, relief claim and tax calculation
