Alternative finance: when SDLT business relief can be withdrawn
Alternative finance and SDLT relief
A business relief allowed through alternative finance can be withdrawn during a three-year control period.
- The key person is normally the customer using the finance, not the lender.
- A further SDLT return is due within 30 days if relief is withdrawn.
- Evidence of business use and unexpected events can be crucial.

Alternative finance: when SDLT business relief can be withdrawn
Alternative finance: when SDLT business relief can be withdrawn
If you used alternative finance to buy property for a business, stamp duty relief may not be final when you complete.
HMRC says it can be taken back during a three-year check period. If this happens, you must deal with the extra SDLT. The finance provider does not pay it.
What this rule is about
Alternative finance can mean that a financial institution buys land before selling it to you, leasing it to you, or buying it with you.
The law adjusts the SDLT rules. This allows a qualifying business relief to apply to the first part of the arrangement.
There is a catch: the relief has conditions that continue. The three-year period starts on the effective date of the first transaction. This date may be before the later step in the finance arrangement.
This can still matter well after completion.
What the official source says
HMRC’s manual says that the same three-year control period applies when alternative finance is used, and it says that you or your business must check the position throughout that period.
You or your business is the relevant person. It is not the financial institution.
- The relevant person is the person, not the finance provider, who entered into the arrangement.
- For the business relief, use the property interest only for letting, property trading, or redevelopment.
- The relevant person must not allow a person who does not qualify to live in a home on the land while holding the interest.
- The relevant interest can include the interest received in the second transaction.
- It can also include an interest passed on when someone uses rights under the finance arrangement.
- An interest that comes from either of those interests can also count.
The legislation allows a limited exception if an unexpected change is outside the relevant person’s control. Even then, the exception does not apply automatically.
If the planned activity has not begun, or it began and then stopped during the three-year period, the relevant person must take reasonable steps to begin it or start it again.
This duty matters.
What this means in practice
Do not assume that the financial institution remains responsible because it filed a return for the first step.
If relief is withdrawn, you pay the extra SDLT. The law places that duty on the relevant person.
You must also send HMRC a further SDLT return within 30 days after the disqualifying event. That return must include your own calculation of the extra tax.
Use the effective date of the original transaction that received relief. Use that date for the calculation.
- Keep the original SDLT return and any relief calculation.
- Record the first transaction’s effective date clearly.
- Keep proof that the property is used for the business.
- Check any change in occupation, ownership, or business plans straight away.
How to analyse it
Look at the arrangement itself first, not the name of the finance product. Then check what happened in the three years after the effective date of the first transaction.
- Find the first and second transactions in the alternative finance arrangement.
- Check which relief was allowed and why it applied at the start.
- Work out the exact three-year control period.
- List each relevant property interest held during that period.
- Check how each interest was used, including any home on the land.
- Ask whether an unexpected event changed the position.
- Gather proof of reasonable steps to continue, begin, or restart the planned use.
- If relief was withdrawn, identify the first day when a requirement was not met.
Example
Amir uses an alternative finance arrangement to get a property for a business that lets commercial property. Relief is allowed for the first transaction.
Eighteen months later, the business stops using the property as planned.
This does not always end the relief. An unforeseen event outside Amir’s control may have caused the problem. If Amir takes reasonable steps to restart the planned use, the statutory exception may matter.
If it does not apply and a requirement has failed, Amir must submit the further return. The financial institution does not take on that job.
Why this can be difficult in practice
The hard part is often the facts. A change in plans is not always unforeseen. A business delay is not always outside your control.
Emails and board notes may matter, as may marketing records, building contracts, and records that show attempts to let or redevelop the property while the business was affected.
Keep these records.
HMRC’s manual says the relevant interest must be held throughout the control period. The statutory wording gives more detail. It refers to relevant interests held by the relevant person.
Check sales, transfers, endings, and replacements with care. Test each point against the legislation.
- People often focus on the financial institution instead of the person using the arrangement.
- People may use the later transaction date instead of the first transaction’s effective date.
- A pause in business activity needs proof of reasonable steps, not just an intention to restart.
- The unforeseen-event exception does not remove all the conditions of the relief.
Key takeaways
- The control period lasts three years from the first transaction’s effective date.
- If relief is withdrawn, the relevant person, not the finance provider, must report and pay extra SDLT.
- Keep clear proof of the property’s business use and any unexpected break.

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
- HMRC says the relevant property interest must be held by the relevant person throughout the three-year period. The statutory wording needs careful checking where the interest has been transferred, ended or replaced.
- Whether a change was unforeseen, beyond the relevant person’s control, and whether reasonable steps were taken will depend on the evidence.
- The supplied statutory text is current only to 17 November 2025. Current-law verification is needed for a transaction 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 dates of the first transaction and any later change
- The alternative finance documents and details of both transactions
- Records showing how the property was used during the three years
- Evidence of any unexpected event and why it was outside your control
- Evidence of steps taken to begin or restart the intended business use
