Guide to Three-Yearly LBTT Lease Review and Tax Adjustments in Scotland

LBTT lease reviews every three years

In Scotland, tenants of most LBTT-notifiable leases must file a further return every third anniversary of the relevant review date, even if nothing has changed and no extra tax is due. At each review, the tenant must recalculate the tax using the actual rent paid so far and the projected rent for the rest of the lease, while still using the LBTT rates and bands that applied when the original lease first became effective.

• A further LBTT return is usually required every three years from the original effective date, but some leases use a later triggering event instead.
• The review return must be filed within 30 days starting the day after the review date, and any extra tax must be paid or any repayment claimed.
• The recalculation uses actual past rent and expected future rent, but ignores any later changes to LBTT rates and bands.
• A review return is still required even if the lease has not changed or the recalculation produces no extra tax.
• If the lease is assigned or terminated on the same day as a review date, only the assignation or termination return is needed.
• The rules do not apply to leases outside LBTT or to leases fully relieved from LBTT, and the filing duty normally remains with the tenant unless there has been an actual assignation.

LBTT lease reviews every three years: when a further return is required and how the tax is recalculated

This page explains the LBTT rules that require tenants to review the tax position on a lease at regular intervals. In Scotland, a lease can stay in place for many years and may change over time. LBTT deals with that by requiring a further return at set review points, rather than a new return every time something changes. This matters because extra tax may become due, or an overpayment may be reclaimed, even where the original lease return was correct when filed.

What this rule is about

LBTT on leases is not always a one-off calculation. The tax is based on the lease as it stands, including the rent and term, and those figures can change after the lease starts. A lease may be varied, extended, assigned, terminated, or continue beyond its original fixed term. Rent may also turn out to be higher or lower than first expected.

Instead of requiring a fresh LBTT return every time one of those things happens, the legislation generally uses a three-year review system. At each review date, the tenant must reassess the tax chargeable on the lease and file a further return. Revenue Scotland says this return tells it what has changed since the original effective date or the last review date, and recalculates the net present value of the rent.

This is different from SDLT. The source material expressly notes that the LBTT approach is not the same as the SDLT position.

What the official source says

The core rule is that the tenant must submit a further LBTT return at every third anniversary of the relevant starting date for the lease and account for any additional tax, or claim any repayment due.

A review return is required even if:

• nothing has changed under the lease, or
• no extra tax is payable.

For most leases, the review date is every third anniversary of the effective date of the original LBTT-notifiable lease. The return and any payment are due within 30 days beginning with the day after that review date.

The return must reassess the tax chargeable by recalculating the lease position using:

• the actual rent for the period that has already passed, and
• the projected rent for the remainder of the lease term.

The calculation continues to use the rates and bands that applied at the effective date of the original lease. Later changes to LBTT rates and bands are ignored for this purpose.

The source also identifies situations where the review date is not based on the original effective date, but instead runs from the event that first made a further LBTT return necessary. These include:

• a contingency ceasing or consideration becoming ascertained,
• the lease continuing beyond its fixed term,
• an indefinite lease continuing beyond the end of a deemed fixed term, and
• an extension of term or increase in rent that made the lease notifiable.

The review date is the “relevant date” for the return. The “effective date” for the review return remains the effective date of the original lease transaction.

The source also states that these three-year review provisions do not apply to:

• leases that were never subject to LBTT and remain under SDLT or Stamp Duty, or
• leases that were subject to LBTT but fully relieved from charge on the first return or an amendment to it.

If a lease is assigned or terminated on the same day that a three-year review would otherwise fall due, only the assignation or termination return is needed. A separate three-year review return is not required in that case.

What this means in practice

The practical effect is that tenants cannot simply file the original LBTT lease return and forget about it. They need to track the lease over time and diarise review dates.

At each review point, the tenant must ask whether the tax originally paid still matches the lease as it now stands. Common reasons for a difference include:

• rent reviews, especially turnover rents or estimated rents,
• an agreed extension or reduction of the lease term,
• a change in the area let, with a matching change in rent, and
• the lease continuing in a way that triggers further LBTT treatment.

If the recalculation produces a higher tax figure than the total already paid, the difference must be paid with the review return. If it produces a lower figure, the tenant can claim repayment in the review return.

The source makes an important timing point. A variation such as an increase in rent or an extension of term is usually not reported immediately when agreed. Instead, it is picked up on the next three-year review return, unless some separate rule makes a return necessary.

The source also notes that if consideration other than rent is paid by either party for the variation, that may itself be treated as a chargeable interest. That is a separate issue from the routine three-year review and needs to be considered on its own facts.

Another practical point is responsibility for filing. The obligation remains with the tenant even if the tenant has granted a standard security over the lease, granted a floating charge, or entered insolvency. Revenue Scotland’s view is that those events do not amount to an assignation of the tenant’s lease interest, so the tenant remains the person with the filing obligation. Where the tenant is a company or LLP in liquidation or administration, the liquidator or administrator becomes the “proper officer” personally responsible for ensuring the returns are made.

How to analyse it

A sensible way to approach the issue is to work through these questions.

• Was the lease an LBTT-notifiable lease in the first place? If not, the three-year review regime may not apply.
• Was the lease fully relieved from LBTT on the original return or an amendment? If so, the source says the review provisions do not apply.
• What is the correct review date? In most cases it is every third anniversary of the original effective date, but some leases use a different starting event under the legislation.
• Has the lease been assigned or terminated on that same day? If yes, only the assignation or termination return is required.
• What has actually happened since the last return? Check rent actually paid, any revised rent projections, any extension or shortening of term, any reduction or increase in area, and any continuation beyond the original term.
• Does the recalculation use the original effective date rates and bands? It should. Later rate changes are not used.
• Is there any separate non-rent consideration for a variation? If so, that may raise a separate chargeable interest issue.
• Has the filing deadline been diarised correctly? The return and any tax are due within 30 days beginning with the day after the review date.

In practice, the most important records are the original lease return, any earlier review returns, rent schedules showing what was actually paid, and documents recording any variation, extension, assignation, or termination.

Example

Illustration: a tenant took a 15-year LBTT lease with an effective date in 2015. The original return used an annual rent of £45,000. The tenant filed review returns in 2018 and 2021. In 2022, the landlord and tenant agreed to increase the annual rent to £70,000.

Under the source material, the tenant does not usually file a return immediately just because the rent changed. Instead, the increase is included in the next three-year review return, due on the next third anniversary review date. At that point, the net present value is recalculated using the actual rent paid so far and the projected rent for the rest of the term. The tax rates and bands used are still those in force at the original 2015 effective date. If the recalculation shows more LBTT is due, the tenant pays the difference with that review return.

Why this can be difficult in practice

The rules are simple in outline but can be awkward in real cases.

First, the correct review date is not always obvious. Most leases use the original effective date, but the source identifies several statutory situations where the review cycle instead runs from a later triggering event. If the wrong date is used, the return may be late or incomplete.

Second, leases with variable or turnover rent require judgement because the review looks backwards to actual rent and forwards to projected rent. The historical figures may be clear, but future estimates may still be uncertain.

Third, not every lease change is dealt with in the same way. A routine rent or term variation may wait until the next three-year review, but non-rent consideration for a variation may raise a separate chargeable interest question. That means the parties should not assume every variation can simply be left until the next review.

Fourth, taxpayers sometimes miss the requirement to file a return where nothing has changed. The source is explicit that a review return is still mandatory even if the tax calculation comes out exactly the same.

Finally, insolvency and secured lending can create confusion about who must file. The source makes clear that the tenant remains the person liable unless there has been an actual assignation, but the practical responsibility may sit with a liquidator or administrator as the proper officer.

Key takeaways

• For most LBTT leases, the tenant must file a review return every third anniversary, even if nothing has changed and no extra tax is due.
• The tax is recalculated using actual and projected rent, but always with the rates and bands in force at the original effective date.
• Variations to rent or term are usually picked up at the next three-year review, but assignations, terminations, and some other events have their own rules.
