Joint buyers: one SDLT return, but shared responsibility
Joint buyers and SDLT
Buying with someone else means one SDLT return, not one return for each ownership share. Each buyer must confirm it, and each may be responsible for the full unpaid amount.
- One return covers the whole purchase
- Each joint buyer makes the declaration
- HMRC can seek unpaid SDLT from either buyer

Joint buyers: one SDLT return, but shared responsibility
When you buy a home with someone else, you will usually make one stamp duty land tax return for the purchase, even if you own different shares. Both of you must make the declaration.
HMRC can pursue either of you for unpaid SDLT.
What this rule is about
Buying together does not divide the SDLT paperwork into separate parts, whether you own equal shares or different shares. Ownership shares do not change that.
The key point is simple: there is one property purchase and one return for it. Your share of the home does not give you a separate SDLT return.
If one buyer leaves the paperwork to the other, both names still matter. Neither buyer is removed from the process.
What the official source says
The law applies where two or more buyers are, or will be, entitled to own a land interest together. Where the purchase must be reported to HMRC, section 103 requires one SDLT return.
- You cannot each send a separate return for your own share.
- Each buyer must make the declaration on the return.
- The declaration says the return is correct and complete to the best of that person’s knowledge.
- Any one joint buyer may meet an obligation for all of them.
- Responsibility for SDLT is joint and several.
Joint and several is an important phrase: if SDLT remains unpaid, HMRC may demand the whole amount from either buyer, regardless of the percentage of the property that person owns. It is not limited to an ownership share.
HMRC’s manual also sets out its view on some special arrangements. The manual is HMRC guidance, not the law itself.
- For a partnership, all partners may sign.
- HMRC says a partnership representative nominated to it may sign instead.
- If trustees are named as buyers, HMRC says any one trustee may sign.
- HMRC says a nominee or bare trustee cannot sign instead of the real buyer.
What this means in practice
One person may handle the practical filing and payment, but that does not remove the other buyer’s responsibility for the return or the tax. Both buyers remain responsible.
Do not treat the person handling the conveyancing as the only person affected. Before signing, each buyer should read the return and check the facts that relate to them.
- Make sure every joint buyer is shown correctly.
- Check that the ownership arrangement matches the property documents.
- Read the declaration before it is made.
- Keep a copy of the completed return and payment record.
- Agree between yourselves who will provide funds for the SDLT.
A private agreement about who will pay may help between the buyers. It does not prevent HMRC from seeking an unpaid amount from either of them.
How to analyse it
Begin by identifying who is actually buying the property, because names on the documents may matter while a trust or nominee arrangement can require further checking. Do not rely on the title paperwork alone.
- Are two or more people buying the property together?
- Will they be jointly entitled to own the interest being bought?
- Does the purchase require an SDLT return?
- Have all the joint buyers made the required declaration?
- Is a partnership, trust, nominee, or bare trustee involved?
- Who has paid, or will pay, the SDLT amount due?
Ask early whether, if the SDLT were unpaid and HMRC pursued either buyer for the entire amount under the joint and several rule, that buyer could pay it. That is the risk each buyer takes on.
Example
Amir and Beth buy a flat for £420,000. Amir will own 60% and Beth will own 40%. They might assume that each should send an SDLT return for their own share.
That is wrong. They make one return for the whole purchase, and both make the declaration. If SDLT remains unpaid, HMRC may seek the unpaid amount from Amir, Beth, or both.
Their 60:40 split does not limit HMRC to collecting 60% from Amir and 40% from Beth.
Why this can be difficult in practice
Problems often arise when one person takes the lead on a purchase and the other assumes that ownership shares determine responsibility to HMRC. They are different things.
Trust and nominee arrangements need extra care. A person may appear on the title paperwork without being the real buyer for SDLT purposes.
HMRC’s manual says that a nominee or bare trustee cannot make the declaration instead of the actual buyer.
- Different ownership shares do not create separate SDLT returns.
- Paying less towards the purchase does not necessarily limit HMRC’s recovery options.
- A person should not sign a declaration without checking the information.
- Partnership and trust arrangements may have special rules.
- The paperwork should show clearly who is acting in what role.
Key takeaways
- Joint buyers make one SDLT return for the purchase.
- Every joint buyer must make the declaration.
- Either buyer can be pursued for unpaid SDLT.

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 supplied statutory text is current only for changes known to be in force on or before 17 November 2025. The position for a transaction after that date needs checking against the current official legislation.
- Whether a person is the real buyer, a trustee, a bare trustee, or a nominee can depend on the legal documents and 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 contract and transfer showing who is buying the property
- The SDLT return and declarations made for each buyer
- Any trust deed, nominee agreement or partnership authority
- Evidence of who paid any SDLT due
