Understanding Rent Payable Before Lease Grant and SDLT Implications
SDLT treatment of payments for periods before a lease is granted
For SDLT, a lease term usually starts on the date the lease is actually granted, not an earlier date written into the document. So, payments linked to a period before grant will not normally count as rent under the new lease, although they may still be taxable as other chargeable consideration, often as a premium. Special care is needed for renewal leases and cases where the tenant occupied the property before the formal lease was signed.
- A backdated start date in a lease does not usually change the SDLT start date for the term.
- If no payment is due under the new lease for the pre-grant period, there is normally no SDLT rent charge for that period.
- If a payment is due for a pre-grant period, it cannot usually be treated as rent under the new lease and may instead be taxed as a premium.
- Where the tenant was already in occupation before grant, SDLT may already have arisen under notional lease rules on substantial performance of an agreement for lease.
- Some backdated renewal leases are an exception, as SDLT may treat the new term as starting on the earlier stated date if the statutory conditions are met.
- The correct SDLT treatment depends on the legal basis of the payment, the timing of occupation, and whether it relates to the new lease, an earlier agreement, or the old lease during holding over.

Understanding Rent Payable Before Lease Grant and SDLT Implications
SDLT and amounts paid for a period before a lease is actually granted
This page explains how SDLT treats payments that relate to a period before a lease is formally granted. This matters because a lease document may say that its term starts earlier than the date it was signed, but SDLT does not always follow that wording. The key question is whether a payment for that earlier period counts as rent under the new lease, falls outside SDLT on the new lease, or is instead taxed in some other way, often as a premium.
What this rule is about
Sometimes a lease is drafted so that its stated commencement date is before the date of grant. That can happen for several reasons:
- to align dates across several leases in the same development
- to cover a period when the tenant was already in occupation under an agreement for lease
- to backdate a renewal lease so it runs from the day after the previous lease ended, during a holding-over period
In property law, a lease cannot actually vest an interest in land retrospectively. For SDLT, that matters because the tax treatment of “rent” depends on when the lease term is treated as starting and what the payment is really for.
The official material is dealing with a narrow but important point: if money is paid for a period before the lease was granted, is that money rent under the new lease, or something else?
What the official source says
The general SDLT rule is that the term of a lease starts on the date the lease is granted, not on an earlier date written into the document.
There is one specific exception mentioned here: certain backdated renewal leases. Where:
- the tenant remains in occupation after the old lease’s contractual end date,
- the tenant is then granted a new lease of the same or substantially the same premises, and
- the new lease says it begins on or immediately after the old lease’s contractual termination date,
the SDLT rules treat the term of the new lease as starting on that stated date. This exception comes from Schedule 17A paragraph 9A FA 2003.
Apart from that exception, “rent” for SDLT cannot include consideration for a period before the lease was granted. The source says that whether a payment is chargeable as rent depends on three practical questions:
- is the landlord entitled to the payment under the terms of the lease?
- does the payment relate to the period before grant?
- does it relate to the new lease, or to an earlier agreement or notional lease?
The source also makes an important further point. If an amount relates to the pre-grant period and to the new lease, but cannot be taxed as rent, it does not simply disappear. It is still chargeable consideration and may be taxed as a premium for the grant of the lease.
What this means in practice
The wording of the lease is not the whole story. For SDLT, you need to identify what legal right the landlord has to the money and what period and arrangement the money really relates to.
In practice, the analysis usually falls into one of these categories.
1. No entitlement to payment for the pre-grant period under the new lease
If the landlord has no right to recover any amount for the period before grant, there is no SDLT charge on rent for that period under the new lease. This is common where the lease is backdated only for administrative convenience, such as aligning review dates across a development.
2. There is payment for the pre-grant period, but it cannot be rent under the new lease
If the landlord does have a right to receive an amount connected with the pre-grant period, that amount cannot be treated as rent under the general rule. The source says it will instead be chargeable consideration and may be taxed as a premium for the grant of the new lease.
This distinction matters because rent and premium are taxed differently under the SDLT lease rules.
3. The tenant was already in occupation before grant
Where the tenant occupies before the formal lease is granted and pays consideration, the source says this will normally be treated as rent under a notional lease created on substantial performance of an agreement for lease. That means the pre-grant occupation may already have triggered SDLT consequences before the formal lease is signed.
When the later formal lease is granted, its SDLT treatment must be considered in light of that earlier notional lease position.
4. Backdated renewal leases
Some renewal leases are treated differently. If the statutory conditions for the renewal lease exception are met, the term of the new lease starts on the date stated in the lease, even if that is before the grant date. In that situation, the backdating can affect the SDLT treatment of the rent in a way that would not apply under the general rule.
The source also notes a separate special treatment issue for some older renewal leases where later legislation does not apply, especially leases granted before 19 July 2006 or renewals of stamp duty leases.
How to analyse it
A sensible way to approach the issue is to work through the following questions.
When was the lease actually granted?
For SDLT, that is usually the starting point for the lease term unless the renewal lease exception applies.
Does the lease say it starts earlier than the grant date?
If so, do not assume SDLT follows that earlier date. Check whether this is merely drafting, or whether the lease is a qualifying backdated renewal lease.
What is the payment for?
Identify whether the amount relates to occupation before grant, to the new lease itself, to an earlier agreement for lease, or to a holding-over period under the old lease.
Is the landlord entitled to recover that amount under the new lease?
If there is no entitlement, there may be no SDLT charge on rent for that earlier period under the new lease.
If there is an entitlement, is it capable of being rent?
Outside the renewal lease exception, consideration for a pre-grant period cannot be rent under the new lease for SDLT purposes. It may instead be premium.
Was there substantial performance of an agreement for lease?
If the tenant went into occupation and paid for that occupation before the formal lease was granted, the SDLT position may need to be analysed through the notional lease rules.
Is this an older renewal case involving a previous stamp duty lease?
If so, the source indicates that the answer may depend on the facts, including whether any increased amount was really agreed as consideration for the new lease or was simply treated as payable under the old arrangement.
Example
Illustration: a tenant agrees to take a new shop lease. The lease is signed on 1 October, but it says the term begins on 1 July so that all leases in the parade have the same review date. The tenant does not have to pay anything for July to September under the lease.
On these facts, the earlier stated commencement date does not by itself create SDLT rent for July to September. Under the general rule, the lease term starts on grant for SDLT purposes, and there is no rent charge for the pre-grant period because the landlord is not entitled to any payment for that period.
Now change the facts. Suppose the lease signed on 1 October requires the tenant to pay an amount described as rent for July to September under the new lease. The source indicates that this amount cannot be rent for SDLT purposes for that pre-grant period. It may instead be chargeable consideration taxed as a premium for the grant of the lease.
Why this can be difficult in practice
The difficulty is that the same commercial outcome can be documented in different ways, and SDLT depends on the legal character of the payment, not just the label used.
In particular:
- a lease may be backdated only for administrative convenience, with no real payment obligation for the earlier period
- occupation before grant may point to a notional lease on substantial performance, which is a separate SDLT analysis
- in a renewal situation, it may be unclear whether payments during holding over relate to the old lease, the new lease, or an agreed inducement for the new lease
- for certain older renewal cases, the source says the answer is a question of fact, especially where rent increased during the holding-over period
The source gives a practical distinction for those older renewal cases. If the amount payable during the holding-over period is the same as under the old lease, it is treated as relating to the old lease. If the amount increased, the reason for the increase matters. If the increase was agreed in order to secure the new lease, the increase may be taxed as a premium for the new lease. If not, the increase may instead be treated as relating to the old lease, potentially as a variation with its own SDLT consequences.
So the correct answer often depends on the documents, the timing of occupation, the existence of an agreement for lease, and what the parties actually agreed the payment was for.
Key takeaways
- For SDLT, a lease term usually starts on the date of grant, not an earlier date written into the lease.
- Amounts for a pre-grant period are not usually rent under the new lease for SDLT, though they may still be chargeable consideration, often as premium.
- Backdated renewal leases and pre-grant occupation under an agreement for lease need separate analysis because special rules may apply.
