The SDLT minimum consideration rule explained
This rule can raise the amount used to work out stamp duty land tax. It matters where a property deal has steps before completion and the final buyer has a close link with a seller. Most ordinary home buyers can ignore it.
What this rule is about
Some property deals involve a chain of contracts or transfers before the final buyer takes ownership. The law has special rules for these pre-completion steps.
The minimum consideration rule stops a linked party from using a low figure for the final step when a higher amount was paid elsewhere in the chain. That distinction can change the stamp duty bill.
What the official source says
The legal rule is in paragraphs 12 to 14 of Schedule 2A to the Finance Act 2003. HMRC’s manual says the rule applies only if the final buyer is connected with a seller, or if the parties are not dealing independently, even where pre-completion transactions occurred before the final purchase. Those conditions limit the rule.
- A direct seller may provide the link.
- An earlier seller in the chain can also provide it.
- There must be pre-completion transactions before the final purchase.
- Where it applies, the rule can increase the amount used for tax.
- That amount rises only where a statutory minimum is higher.
- There are two possible minimum amounts to compare.
What this means in practice
The final transfer price alone does not decide it. You may need to look back through the whole chain of arrangements.
One minimum is usually the amount due under the original contract. The other is calculated by a formula that traces the net amounts given by each party throughout the arrangements, while taking account of exceptions identified in the official source. The exceptions can change the result.
- Start with the amount produced by the normal SDLT rules.
- Work out the first statutory minimum amount.
- Work out the formula-based minimum amount.
- Use the higher minimum if it exceeds the normal amount.
- Keep documents showing payments and other value passed between parties.
How to analyse it
Ask the relationship question first. If the parties are neither connected nor acting other than independently, HMRC says the rule can be left out of account.
- Who is the final buyer?
- Who transferred the property at each earlier step?
- Are any of those people or entities connected?
- Were the parties dealing independently?
- What did the original contract require to be paid?
- What did each party give and receive across the chain?
- Do any formula exceptions apply?
Example
Imagine that Priya is the final buyer in a transaction chain. The normal SDLT calculation produces an amount paid figure of £100,000. The original contract required £300,000, while the formula gives £250,000. The calculation uses £300,000 because the first minimum is highest. This is a simplified illustration and assumes the rule applies.
Why this can be difficult in practice
This is the part people can miss: the relevant relationship may be with an earlier seller, not only the person selling to you on completion. A low final price does not settle the point.
Applying the formula can also be difficult. It measures the net amounts given by each party. Official guidance notes that exceptions apply.
- A family, company or trust link may need careful checking.
- A chain can contain more than one earlier transfer.
- Payments may not tell the full story if other value changed hands.
- You cannot safely derive the formula from the final contract alone.
Key takeaways
- The rule is mainly relevant to connected or non-independent parties.
- It can increase the amount used to calculate stamp duty.
- Check the full chain, not just the final sale price.

Where this is not settled
- Whether people are connected or are dealing independently can depend on the full facts.
- The supplied HMRC page does not set out the detail of the formula exceptions.
Evidence you would need
