Stamp duty relief for diplomatic and consular premises
When a diplomatic mission or consulate buys or leases certain official premises in England or Northern Ireland, it may receive stamp duty land tax relief if the property has the required official role. Private homes do not qualify merely because a diplomat works for a mission.
What this rule is about
This narrow relief applies where premises are used by a diplomatic mission or consulate, including when they serve as the official home of the head of the mission or consular post. It does not extend further.
Because an official residence and a private home can both look like ordinary houses, their use and status decide whether the relief applies. Appearances do not decide it.
HMRC’s manual points to international convention rules that have been brought into UK law. It is HMRC guidance, not the law itself.
What the official source says
HMRC says that relief is available for a purchase or lease of the following types of property. Before claiming it, the mission or consulate must obtain confirmation of the property’s diplomatic status.
- Premises of a diplomatic mission can qualify.
- The official residence of the head of a diplomatic mission can qualify.
- Consular premises can qualify.
- The official residence of the consular head can qualify.
- A diplomat’s private residence does not qualify.
- A consular official’s private residence does not qualify.
When completing a claim at Question 9 of the land transaction return, HMRC’s manual directs the mission or consulate to use relief code 27. The mission or consulate should first obtain confirmation from the Foreign and Commonwealth Office Protocol Directorate’s Diplomatic Missions & International Organisations Unit.
What this means in practice
Do not start with who will live in the property. Start with what the property is for. A house used as the official residence of a head of mission may fall within HMRC’s description, whereas that same person’s private home does not. Only the first category is within HMRC’s description.
That may sound like a fine distinction. It can decide whether stamp duty is due.
- Keep evidence of the property’s official role from the outset.
- Obtain status confirmation before using the relief code on the return.
- Check whether the transaction is a purchase or a lease of the qualifying premises.
- Do not treat employment by a mission or consulate as enough on its own.
How to analyse it
Ask the questions in this order. The source does not give a wider exemption for every property connected with diplomatic staff.
- Is the property in England or Northern Ireland?
- Is the transaction a purchase or lease?
- Is it premises of a diplomatic mission or consulate?
- If it is a home, is it the official residence of the relevant head?
- Or is it instead a private residence for a diplomat or consular official?
- Has the required status confirmation been obtained?
- Has the return been completed using the code stated in HMRC’s manual?
What actually decides the issue? Not the job title alone. What matters is whether the premises have the official status described by the source.
Example
Illustration: a consulate takes a lease of a building for its official offices. It obtains confirmation that the building has the required consular status. HMRC’s manual identifies this as the type of lease for which a claimant can claim relief using code 27.
Change one fact. If the consulate instead leases a flat as the private home of one of its officials, the manual says the relief does not apply. The official’s work does not turn their private home into consular premises.
Why this can be difficult in practice
In practice, people often focus on the person who will occupy a property. That is understandable, but it is not enough. Establishing the official status of the premises is the point.
Rather than providing a full explanation of every borderline case, the manual gives an administrative route. It does not describe the evidence needed to separate an official residence from a private one.
- A property may be used by diplomatic staff without being official mission premises.
- A home connected with a head of mission may still need its status confirmed.
- The source uses an older government department name, so current contact arrangements may have changed.
- Return questions and relief codes can change, so the filing method should be checked before submission.
Key takeaways
- Relief is limited to specified diplomatic and consular premises.
- An official residence can qualify, but a private home cannot.
- Obtain status confirmation before making the claim described by HMRC.

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 material does not set out the detailed legal test for deciding whether a particular property is an official residence or private home.
- The source uses the former Foreign and Commonwealth Office name. Current contact details and the current return process should be checked before filing.
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 or lease showing what property is being obtained.
- Confirmation of the diplomatic or consular status of the premises.
- Records showing whether the property is mission, consular or official-head accommodation.
- The completed land transaction return and the relief code used.
