When do you pay stamp duty after buying a home?
SDLT payment deadline
For most transactions from 1 March 2019, SDLT is due within 14 days of the effective date. A late payment may attract interest, and a late return may attract penalties.
- Check the effective date, not just the moving date.
- Pay extra SDLT straight away after a late amendment.
- Watch for a further return if relief is withdrawn.

When do you pay stamp duty after buying a home?
For most purchases in England and Northern Ireland, stamp duty land tax, or SDLT, must be paid within 14 days of the effective date. In most cases, that is also the deadline for sending the SDLT return. Miss the deadline and interest may build up.
What this rule is about
Buying a home brings many deadlines. SDLT has one of its own: tax is due by the filing date for the return. The filing date is the final day on which that return can be sent.
Most people concentrate on the tax amount. The timing matters too. A late payment can increase the cost, even if the original SDLT figure was correct.
What the official source says
HMRC’s manual says that, for transactions from 1 March 2019, SDLT is payable within 14 days of the effective date under the applicable rule. Earlier transactions had a 30-day deadline.
- You must normally pay SDLT by the filing date for the return.
- Where you amend a return before or on that date, any additional tax is still due by the filing date.
- If you amend it after the filing date, extra tax must be paid straight away.
- Late payment can lead to an interest charge.
- A late SDLT return can also lead to penalties.
- When HMRC issues an assessment or determination, the tax must be paid within 30 days after its issue.
The manual also deals with a later change in position. Where relief was claimed but is later withdrawn, a further return and any tax due must reach HMRC within 30 days.
- The manual gives group relief as one example.
- It also lists reconstruction or acquisition relief and charities relief.
- It refers to relief for first-time buyers and some higher-rate transactions.
- It lists the relief for buying more than one home at once, but says it was abolished from 1 June 2024.
What this means in practice
Because the SDLT return and payment timetable run together, do not regard the return as paperwork that can wait until after the move, even if your conveyancer arranges both. Know the key date.
When new information increases SDLT after you have filed, the payment timing changes. A late correction does not give you another 14 days in which to pay the extra amount.
- Keep the completion papers and SDLT return together.
- Check the effective date used on the return.
- Make sure the payment covers the tax shown on the return.
- Act quickly if you discover an error that means more tax is due.
How to analyse it
Start with the effective date. From there, work forwards, and do not assume that registration or any other date in the purchase sets the SDLT deadline, because the rules may treat another date as effective. Use the rules’ date.
- Identify the effective date of the transaction.
- Check whether it falls on or after 1 March 2019.
- Work out the filing date from that date.
- Check whether the original return and payment met that deadline.
- Ask whether a later amendment increased the SDLT.
- Check whether any relief claimed has since been withdrawn.
- Read any HMRC notice carefully and record its issue date.
Example
Sam’s effective date is 5 May. The normal 14-day deadline ends on 19 May. On 12 May, Sam sends an amended return that increases the SDLT, so the extra amount remains due by 19 May.
Now change one fact. Sam finds the error on 23 May and amends the return at that point. As the filing date has passed, the extra SDLT is due straight away. Waiting for a later payment run may create interest.
Why this can be difficult in practice
Here, the phrase “effective date” carries significant weight because it may not be the date on which keys are handed over, while the facts and terms of the purchase can matter. Do not make assumptions.
Relief can create a second deadline as well. Paying less SDLT at the start may be correct, but a later event can remove that relief. The 30-day clock then runs from the relevant event rather than the original purchase date.
- People often record the completion date but not the effective date.
- An amended return can create an immediate payment duty.
- A late return and late payment are separate problems.
- An appeal does not automatically stop tax being due.
- Deferral for uncertain future payments uses separate rules.
Key takeaways
- For most current SDLT purchases, pay by the 14-day filing date.
- Extra SDLT found after that date must be paid straight away.
- Keep track of relief conditions after the purchase.

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 exact deadline may need further checking where a transaction has unusual completion arrangements, uncertain future payments, or an appeal.
- Whether a relief has been withdrawn depends on the conditions of that particular relief and the event that occurred.
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 transaction
- the date the SDLT return was filed
- the date and amount of each payment
- any amended return and its filing date
- documents supporting any relief claimed
- any HMRC assessment or determination notice
- details of any application to defer or postpone payment
