Guidance on LBTT transitional rules for pre-implementation leases in Scotland.

LBTT transitional rules for Scottish leases granted before 1 April 2015

LBTT can apply to certain changes made on or after 1 April 2015 to Scottish leases that were originally granted before LBTT began. The transitional rules are designed to make sure the same lease element is not taxed twice under SDLT, Stamp Duty and LBTT, while still bringing any new chargeable element into LBTT.

• A pre-1 April 2015 lease can create a new deemed LBTT lease if it is later assigned in a qualifying case, varied to increase rent within the first five years, or extended in term or premises.
• LBTT usually applies only to the new element, such as the extra rent, the extended period, or the additional premises, not to the whole original lease again.
• The effective date is often the date the variation is signed, but it can be earlier in some cases, such as when possession of extra premises is taken before the paperwork is completed.
• The term of the deemed LBTT lease may differ from the effective date, so filing deadlines and three-year review returns can arise before the extended term actually starts.
• If one variation both increases rent and extends the lease, there may be two deemed leases which are then treated as linked for LBTT purposes.
• Revenue Scotland also takes a practical approach for some older Stamp Duty leases, especially where later changes are similar to events that would have been treated as new lease events under SDLT rules.

LBTT transitional rules for Scottish leases granted before 1 April 2015

This page explains how Land and Buildings Transaction Tax (LBTT) can apply to Scottish leases that were originally granted before LBTT started on 1 April 2015. The main purpose of the transitional rules is to stop leases falling between the old and new tax systems, and to stop the same element being taxed twice under both SDLT and LBTT.

What this rule is about

LBTT replaced SDLT in Scotland from 1 April 2015. That created a problem for leases already in existence at that date. Many of those leases had already been dealt with under SDLT, or in older cases under Stamp Duty. But leases often continue for many years, and they may later be varied, extended, assigned, or replaced.

The transitional provisions decide when a post-1 April 2015 event involving an older lease should be brought into LBTT. They are aimed at a practical result:

• the part already dealt with under SDLT or Stamp Duty should not be taxed again under LBTT, but
• new chargeable elements arising after 1 April 2015 should not escape tax just because the original lease pre-dated LBTT.

The Revenue Scotland guidance covers several situations for pre-implementation leases:

• overlapping leases
• assignation of a previously exempt lease
• variation of rent within the first five years of the original grant
• extension of the term or the premises
• how to calculate NPV for these deemed LBTT leases
• how the three-year lease review rules operate
• how older Stamp Duty leases fit into the same framework

What the official source says

Revenue Scotland says the transitional provisions in the Land and Buildings Transaction Tax (Transitional Provisions) (Scotland) Order 2014 are intended to ensure that relevant transactions are taxed once, under SDLT or LBTT as appropriate, rather than twice or not at all.

In broad terms, the guidance says the following.

• If a new lease overlaps with an old lease granted before 1 April 2015, the overlap relief rules can still apply, even though the old lease was taxed under SDLT rather than LBTT.
• If a lease granted before 1 April 2015 was exempt from SDLT or Stamp Duty because a specified relief applied, the first post-1 April 2015 assignation that is not covered by that relief can be treated as the grant of a new lease for LBTT purposes.
• If a pre-1 April 2015 lease is varied after 1 April 2015 to increase rent within the first five years of the original grant, that variation is treated as the grant of a new lease for LBTT purposes.
• If a pre-1 April 2015 lease is extended after 1 April 2015, whether by extending the term or the premises, that extension is treated as the grant of a new lease for LBTT purposes.

The guidance also makes two important points about scope.

• Where a pre-implementation lease enters LBTT through these transitional rules, only the new LBTT element is taxed. The original SDLT lease does not itself become an LBTT lease.
• For older Scottish leases originally within Stamp Duty rather than SDLT, Revenue Scotland takes a purposive view that the same transitional logic can still apply in relevant cases, especially for extensions and similar changes that would have been within Schedule 17A FA 2003 had SDLT still been in point.

What this means in practice

The key practical point is that a change to an old Scottish lease can create a new deemed lease for LBTT, even though the original lease was never an LBTT lease.

That deemed lease is treated as a separate LBTT event. This means:

• an LBTT return may be required
• the effective date must be identified
• the rent for LBTT purposes must be isolated
• the term of the deemed lease must be identified correctly
• three-year review returns may then be required until the lease contract finally ends

Just as importantly, LBTT is not charged on the whole historic lease merely because there has been a later variation. The guidance is clear that the charge is confined to the additional element brought into LBTT by the transitional rule.

How to analyse it

A sensible way to analyse a pre-1 April 2015 Scottish lease is to work through these questions.

1. Was the original lease granted before LBTT started?

If yes, the transitional provisions may matter. The guidance is specifically about pre-implementation leases, meaning leases granted before 1 April 2015.

2. What happened after 1 April 2015?

You need to identify the later event. The guidance deals with four main types of event.

• A new lease replaces or overlaps with an old one.
• The lease is assigned to a new tenant.
• The rent is increased by variation.
• The term or premises are extended.

3. If rent was increased, did that happen within the first five years of the original grant?

This is critical for Article 12. Revenue Scotland says a variation increasing rent only enters LBTT if the increase occurs within the first five years of the original lease grant. If the increase happens after that five-year period, Article 12 does not apply.

The guidance also says that a rent increase under a periodic rent review, or an increase taking effect after five years from grant, does not by itself bring the SDLT lease into LBTT.

4. If the lease was extended, what exactly was extended?

Article 13 can apply where the term is extended or the premises are extended. That can create a deemed new LBTT lease even if the original lease is much older.

If the extension is of time, the new LBTT lease generally covers the extended period only.

If the extension is of premises, the new LBTT lease generally covers the additional premises for the relevant period.

5. What is the effective date?

The guidance says the effective date is usually the date the variation is signed, or in some cases the date missives are concluded if that itself constitutes the variation. For extensions of premises, if the tenant takes possession of the extra area before the formal minute of variation is signed, that earlier possession date can become the effective date.

This matters because the effective date drives filing deadlines and three-year review dates.

6. What is the term of the deemed LBTT lease?

This is where people often go wrong. The effective date and the term start date are not always the same.

• For a rent increase within Article 12, the term is the period over which the increased rent applies.
• For an extension of term under Article 13, the term of the new LBTT lease is the extended period, starting when the original term ends.
• For an extension of premises, the term starts when the tenant has possession under the new terms relating to those additional premises.

The guidance stresses that a tenant may still occupy the original premises between effective date and term start, but that occupation may remain linked to the old SDLT lease rather than the new LBTT lease.

7. What rent is brought into LBTT?

The starting point is that LBTT should apply only to the new element.

• For a rent increase under Article 12, LBTT applies to the additional rent only.
• For an extension of term, LBTT applies to the full rent payable during the extended period.
• For an extension of premises, LBTT applies to the rent attributable to the additional premises.

If a later rent increase affects both the old SDLT part and the new LBTT part, the increase may need to be apportioned on a just and reasonable basis. Revenue Scotland says this is fact-dependent.

8. Are there two deemed leases that must be linked?

If the same variation both increases rent within the first five years and extends the lease, Revenue Scotland says this is likely to create two deemed leases under Articles 12 and 13. The successive linked lease rules then treat them as a single lease for LBTT purposes.

That affects the term and the rent used in the tax calculation.

9. Does the lease review regime now apply?

Yes, if a deemed LBTT lease has arisen. Three-year review returns run from the effective date, not from the later start of the extended term. This means review returns may be due before the extended period even begins.

Reviews continue until the lease contract finally terminates.

10. Is this an old Stamp Duty lease rather than an SDLT lease?

The guidance says Revenue Scotland takes a purposive approach. In its view, the transitional provisions can still apply to some pre-1 December 2003 Scottish leases where the later event is of a kind that would have been treated under Schedule 17A FA 2003 as a new lease event. The guidance specifically says that extensions and similar cases can potentially be brought into LBTT in this way.

Example

Illustration: a tenant took a 10-year Scottish lease in 2013 and SDLT was dealt with at that time. In 2015, the parties sign a minute of variation extending the lease by another five years at the same annual rent.

Under Revenue Scotland’s guidance, that extension is treated as the grant of a new lease for LBTT purposes.

• The effective date is generally the date the minute of variation is signed.
• The term of the new LBTT lease is not the whole original lease term. It is the extra five-year period only.
• The rent brought into LBTT is the rent payable during that extra five-year period.
• Three-year review returns run from the effective date, even though the extra five years do not start until the original term ends.

So the tenant may have LBTT filing and review obligations well before the extended period starts.

Why this can be difficult in practice

The main difficulty is that the transitional rules split one commercial lease into different tax components.

The original lease may remain an SDLT or Stamp Duty lease, while the later change is treated as a separate LBTT lease. That creates several practical problems.

• The effective date may be different from the start date of the LBTT term.
• Only part of the rent may be relevant for LBTT, so you must isolate the additional or extended element.
• If later rent changes affect both the old and new elements, an apportionment may be needed.
• A single minute of variation may create two deemed leases that then have to be linked.
• Three-year review obligations can arise before any rent is actually payable under the extended term.
• Older Stamp Duty leases require careful handling because Revenue Scotland’s approach is purposive rather than based on a simple literal reading.

Another point of care is assignation of previously exempt leases. Article 11 only applies in a specific class of case: the original lease was exempt because one of the listed reliefs applied, and the first post-1 April 2015 assignation occurs without that relief being available. The guidance also says the rule does not apply where certain reliefs were already withdrawn because of a disqualifying event before the assignation.

Key takeaways

• A post-1 April 2015 change to a pre-LBTT Scottish lease can create a new deemed LBTT lease, even though the original lease was taxed under SDLT or Stamp Duty.
• LBTT generally applies only to the new element, such as additional rent, an extended term, or additional premises, not to the whole historic lease again.
• For transitional leases, identifying the correct effective date, term start, relevant rent, and review timetable is essential.
