The buyer normally has responsibility for the SDLT return and payment. A return is normally due within 14 days of the effective date where the transaction is notifiable.
- Joint buyers can each be pursued for the full tax.
- Later events can create a 30-day further-return deadline.
- Companies, partnerships and trusts have special rules about who acts and pays.

Who must file and pay stamp duty land tax?
When stamp duty land tax is due on a property purchase, responsibility rests with the buyer. The buyer normally must send any required return to HMRC within 14 days of the effective date, even where completion is not the relevant trigger. This is usually completion day.
Missing that deadline can delay a purchase and lead to extra cost.
What this rule is about
Stamp duty land tax, often called stamp duty or SDLT, is not normally the seller’s bill. The buyer must ensure that the tax is paid and that the required return reaches HMRC, even when a conveyancer prepares the papers or submits them. Responsibility remains with the buyer.
A conveyancer can prepare and submit the return for you. However, legal responsibility does not move away from the buyer.
The return also includes the buyer’s declaration. After checking the transaction details supplied, the buyer declares that the information is complete and correct to the best of the buyer’s knowledge. The buyer gives that declaration.
The date matters most because the deadline runs from the effective date, rather than simply from when you first agreed the deal. Check that date.
What the official source says
HMRC’s manual states that the buyer must make a land transaction return and pay SDLT within 14 days of the effective date. The legislation supports that deadline for a notifiable transaction.
- The buyer must pay SDLT due on a taxable transaction.
- A return is required only where the transaction is notifiable.
- The normal filing deadline is 14 days after the effective date.
- The tax due must be paid by that filing date.
- Before 1 March 2019, HMRC says the normal period was 30 days.
- Some later events require a further return within 30 days.
A common reason for a further return is a later event that makes extra tax payable. For example, a payment may have depended on an event that later happens. If certain SDLT relief is later withdrawn, the buyer may also need to make a further return.
HMRC’s manual is guidance rather than the law itself. The Finance Act 2003 provisions determine who must file, pay and make a further return.
What this means in practice
Even where your solicitor prepares the return, arranges payment and deals with completion, do not assume that their involvement removes the deadline from your concern. The deadline remains yours.
Keep track yourself: check who will submit the return, who will arrange payment, and whether completion or another effective date occurs before the deadline. Confirm this early. This is particularly important if the people handling the paperwork are not the buyers themselves.
Joint ownership does not divide HMRC’s claim into neat shares. Although HMRC may require either joint buyer to pay the full amount where payment has not been made, it can recover that amount only once. Not twice.
- If you buy with someone else, both names and the tax details must be right.
- If one joint buyer pays the whole bill, that settles the bill to HMRC.
- A company acts through its proper officer or another authorised person.
- If a company has a liquidator or administrator, special rules identify the proper officer.
- For a partnership purchase, the partners at the effective date are responsible for the SDLT tasks.
- A later partner may also be a responsible partner, but the law limits recovery of tax for the earlier purchase from that person.
- For a settlement trust, one or more responsible trustees may make the return and payment.
How to analyse it
Start with the transaction, then work through the dates and people involved. Do not start by asking only who transferred the money. SDLT responsibility follows the statutory rules.
- Is the property in England or Northern Ireland?
- Is there a land transaction that falls within the SDLT rules?
- Is it a notifiable transaction requiring a return?
- What is its effective date?
- Who is the buyer for SDLT purposes?
- Are there joint buyers, a company, a partnership or trustees?
- Is SDLT due, and has it been paid by the filing date?
- Has a later event made extra tax payable or withdrawn a relief?
What actually determines the deadline? Usually, it is completion. However, special rules can create an earlier or different effective date. That distinction can be expensive.
Example
Amira and Ben complete their purchase on 10 June. Their transaction requires an SDLT return. They must file the return and pay any SDLT within 14 days of that date.
If Ben pays the full tax, HMRC cannot charge Amira the same tax again. However, both remain responsible if the return is wrong or missing.
Now change the facts. The purchase price includes an extra £20,000 if planning permission is granted later. If permission is granted and that event means more SDLT is due, the buyer may need to send a further return and pay the extra amount within 30 days.
Why this can be difficult in practice
Most people focus on the price and completion date. Yet the harder question may be who counts as the buyer, whether a later event has changed the tax, and how those issues apply when property is bought through a business, trust or partnership. Those details matter.
It may seem that a person who joined a partnership later must always pay an old SDLT bill, but that conclusion is too simple. Not necessarily. They can become a responsible partner for SDLT purposes, but the law restricts recovery of tax for the earlier transaction from them.
- Completion may not always be the effective date.
- A later payment can create a new SDLT reporting issue.
- A return can be required even where the immediate tax calculation is nil.
- Joint buyers should not assume responsibility is limited to their ownership share.
- Trustees and partners need to identify everyone holding the relevant role on the key date.
- Company paperwork should show who was authorised to act.
Key takeaways
- The buyer normally bears responsibility for SDLT and the return.
- For a notifiable transaction, the normal deadline is 14 days from the effective date.
- Joint buyers, companies, partnerships and trusts need to apply special responsibility rules.

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
- Whether a transaction is notifiable depends on its facts and the SDLT rules that apply to it.
- The correct effective date can be different from completion in some arrangements.
- The supplied statutory text is current only to 17 November 2025. The position for a later effective date needs checking against current legislation.
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 contract and completion statement
- The completion date and any earlier possession or payment dates
- The SDLT return and payment confirmation
- Details of any later payment, contingency or withdrawn relief
- The names and roles of all joint buyers, partners or trustees
