Stamp duty when part of the property price is paid later
Paying part of your property price later does not usually reduce your stamp duty land tax bill, because SDLT uses the full amount you agree to pay, even if the seller receives some of it years later. Timing does not decide it.
What this rule is about
A delayed payment can make a purchase seem cheaper today, but it does not bring an SDLT reduction. The total agreed price is key.
What the official source says
HMRC’s manual explains that, where some or all of the price is due later, SDLT uses the full amount agreed, and the legislation allows no discount simply because the seller’s right to payment is postponed. Payment timing does not alter it.
- Include money due on completion.
- Include money due at a later time.
- Do not reduce a later payment to a lower value today.
What this means in practice
You cannot treat a deferred payment as worth less for SDLT just because you keep the money for longer, including where a contract splits the price into early and later instalments. Use the whole amount.
- Add up the full agreed amounts.
- Check the contract’s payment timetable.
- Do not apply a present-value discount to a delayed instalment.
How to analyse it
Start with what you have agreed to give for the property, then separate each amount from the date you must pay it. The date changes cash flow, not this SDLT amount.
- Read the contract and any linked agreement.
- List every amount you must pay.
- Identify which sums are due later.
- Use the total without reducing later sums.
Example
Amir agrees to pay £300,000 on completion and £100,000 two years later, so the amount used to work out SDLT is £400,000. It is not reduced because the final £100,000 is paid later.
Why this can be difficult in practice
People often focus on the cash needed at completion, but that is not enough when they must decide whether a later sum is part of the agreed property price or a payment for something else. That can be hard.
- A side agreement may affect the true total price.
- A payment with conditions may need separate analysis.
- Non-cash payments can have different valuation rules.
Key takeaways
- Later payment does not mean a lower SDLT amount.
- Use the full price you agree to pay.
- Keep clear evidence of all payment terms.

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.
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 sale contract and any side agreement showing every sum due.
- The payment schedule, including amounts, dates and any conditions.
