When a lease deposit or loan can increase stamp duty
Lease deposits and stamp duty
A deposit or loan linked to a lease can increase the amount used for stamp duty where repayment depends on the tenant’s conduct or death.
- Deposits up to twice the relevant maximum rent are ignored.
- The exception does not apply to loans.
- The exact repayment terms are crucial.

When a lease deposit or loan can increase stamp duty
A rent deposit does not always fall outside stamp duty land tax. If the tenant can recover it only by doing something, it may form part of what they paid for the lease. That can raise the stamp duty bill.
What this rule is about
Many leases require a tenant to pay a deposit. It may protect the landlord when rent, service charges or other sums remain unpaid. A lease may also include a loan to the landlord or somebody else.
People usually regard a deposit as money that will be returned. This rule looks past that label. It asks whether the tenant must meet a condition before repayment.
The difference may sound slight. It can alter the amount used to calculate stamp duty.
What the official source says
HMRC’s manual explains a rule in the Finance Act 2003 that has applied since 19 May 2005. The rule covers arrangements that parties make when they grant a lease, together with comparable arrangements that they make when they assign that lease. Its scope is broad.
When the test applies, the rule treats the full deposit or loan as a premium. In plain terms, the calculation adds it to the non-rent amount given for the lease. A possible later repayment does not reduce that amount.
- A tenant, someone connected with that tenant, or someone acting for either of them may pay a deposit or make a loan under the arrangement.
- The money may go to the landlord or to somebody else.
- Repayment of all or part may depend on something the tenant does.
- The same result follows when repayment depends on something the tenant fails to do.
- The test also includes repayment depending on the tenant’s death.
- For an assignment, the rule can apply to the incoming tenant instead.
Deposits have an important break. This rule ignores a deposit when it does not exceed twice the relevant maximum rent. The break applies to deposits, not loans.
The relevant maximum rent may not be the rent in the first year. Instead, you must identify the highest rent payable for any continuous 12-month period that falls anywhere within the first five years of the lease, rather than simply use the first year’s rent. Use that peak.
- For a new lease, consider the first five years of its term.
- For an assignment, consider the first five years remaining on the assignment date.
- Find the highest rent due for any continuous 12-month period in that period.
- Double that figure.
- Compare the deposit with that doubled amount.
What this means in practice
First, separate rent from other money paid under the deal. Stamp duty on lease rent has its own calculation. This rule instead treats a caught deposit like a premium.
This particular rule ignores a deposit that falls within the twice-rent limit. That does not put every payment connected with a lease outside the calculation. The terms and purpose of each payment still matter.
A loan calls for extra care. Even a small loan cannot use the deposit exception. If repayment is conditional in the way the law describes, the calculation can include its full amount.
- Do not assume a payment is harmless because the document calls it a deposit.
- Do not deduct an expected future repayment from the amount being tested.
- Check deposits held for service charges as well as deposits linked to rent.
- Check side letters and separate security documents, not just the lease.
- On an assignment, use the remaining term rather than the original lease term.
How to analyse it
The right question is not simply: “Will I get the money back?” Ask instead: “What has to happen before I get it back?”
- Identify every deposit and loan paid in connection with the grant or assignment.
- Check who paid it, who received it, and whether another person acted for the tenant.
- Read the repayment wording closely.
- Decide whether repayment depends on an act, a failure to act, or death.
- If it is a deposit, calculate twice the relevant maximum rent.
- If the deposit is no more than that figure, ignore it for this rule.
- If it is a loan, do not apply the twice-rent exception.
- When the rule catches an amount, include its full value when you work out the premium part of the stamp duty calculation, even though repayment may remain possible later. Use no discount.
Keep the documents that support each answer. Although the lease itself may say little about the deposit, a separate deed may contain the repayment condition that determines the result under this rule. Read both.
Example
Sam takes a ten-year lease of a shop. Rent is £50,000 a year for the first five years. Sam pays a £25,000 rent deposit to the landlord when the lease starts.
The relevant maximum rent is £50,000. Twice that amount is £100,000. The £25,000 deposit is below the limit, so this rule ignores it. The lease rent must still be considered under the separate rules for lease rent.
Now change one fact. Sam pays a £120,000 deposit whose repayment depends on Sam meeting a condition in the lease, so the calculation must test the whole amount against the relevant limit. It exceeds twice the relevant maximum rent. Under this rule, the calculation treats the full £120,000 as a premium, without reducing it because Sam may later receive it back.
Why this can be difficult in practice
This is the point people get wrong: the label on the payment does not settle the issue. A payment called a “refundable deposit” may still fall within the rule if the repayment wording makes it conditional.
Not every restriction on repayment will be easy to classify. The answer can turn on the precise words used and on how the lease documents work together.
- A deposit may cover more than one obligation, such as rent and service charges.
- Rent may rise during the first five years, changing the relevant maximum rent.
- A rent review may need careful treatment when finding that maximum figure.
- The payer or recipient may be a connected person rather than the named tenant or landlord.
- An assignment changes the period used for the rent comparison.
- A loan and a deposit are treated differently because only deposits have the twice-rent exception.
HMRC’s manual gives examples using historic leases and historic thresholds. Those figures should not be used to work out stamp duty on a new transaction. The rate calculation depends on the law in force on its effective date.
Key takeaways
- A conditional lease deposit can count as a premium for stamp duty.
- A deposit of no more than twice the relevant maximum rent is ignored under this rule.
- A conditional loan has no equivalent twice-rent exception.
- Use the full amount, even if it may be repaid later.
- Read all the repayment terms, including separate deposit documents.
Technical analysis

Legislation

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 repayment term is truly contingent can depend on the exact lease, deposit deed and related documents.
- This page does not set out the SDLT rates or thresholds for a current transaction. They depend on the transaction date and property type.
- The supplied statutory text is current only to 17 November 2025. A transaction after that date needs a check 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 lease and any agreement for lease
- The deposit deed or loan agreement
- Evidence of who paid the money and who received it
- The repayment terms and every condition attached to them
- The rent schedule for the first five years, or first five remaining years on an assignment
- The grant or assignment date and property type
