LBTT is a self-assessed tax, and responsibility for an accurate return and any payment rests with the taxpayer. For a commercial lease, the tenant is usually responsible. Revenue Scotland provides an LBTT calculator to help establish the potential liability, although professional tax or legal advice may be needed for complex arrangements.
Practical steps for commercial agents
Late or inaccurate returns can lead to penalties, while unpaid tax attracts interest. Building tax prompts into lease processes means agents can support compliance and provide a valuable extra service to their clients.
Clear records, well-diarised deadlines and early referral for specialist advice can prevent an LBTT obligation from being missed at any stage of a commercial lease.
At a minimum, the file should record the effective date, original transaction reference, lease term, rent profile, premium and future review dates.
LBTT should then be reconsidered whenever:
- a new lease is granted
- a rent, term or property area changes
- a third anniversary approaches
- a lease is assigned
- a premium or other payment is made
- a lease ends or continues beyond its stated term.

When a new lease begins
LBTT may apply when someone leases non-residential land or property in Scotland. It can be charged on both:
- the Net Present Value (NPV) of the rent over the lease term
- any premium or other chargeable payment made for the lease.
A lease is usually notifiable where the NPV of the rent exceeds £150,000. However, the detailed notification rules also take account of the lease term, annual rent and any premium, meaning a transaction may require an LBTT return even where no tax is payable. Agents should avoid relying on the £150,000 NPV threshold alone when advising a tenant to check their position.
A return for a notifiable lease must normally be submitted within 30 days beginning with the day after its effective date. Any tax due must be paid at the same time. Where the lease is to be registered, the return must be made, and the tax paid before registration can take place.

Stamp Duty and Land Tax
This guide covers everything you need to know about how much Stamp Duty or Land Tax you could have to pay on your next home.
Reviews must be diarised
Once a lease has been notified, the tenant will generally need to submit a review return every three years to update Revenue Scotland on changes since the lease began or the previous review. Crucially, the three-year review return is required even if the lease has not changed and no additional tax is due.
This requirement can easily be overlooked once the original transaction has completed. Agents involved in ongoing lease management should record the effective date and three-year review cycle, whilst making clear to the tenant who will prepare and submit each return.
Changes can make a lease notifiable
A return is not normally needed every time an existing notified lease changes, because most are captured in the next three-year review.
There is an important exception where a lease was not originally notifiable but is later varied—for example, by increasing the rent or extending the term—so that it becomes notifiable. The tenant must then submit a first LBTT return within 30 days of the day after the variation takes effect.
Payments made in connection with a variation may also have separate LBTT implications. Agents should encourage the parties to check the tax position before changes are completed, rather than waiting until the next scheduled review.
Assigning the lease transfers future duties
When a notified lease is transferred to another party (assigned), the outgoing tenant must submit an assignation return within 30 days beginning with the day after the assignation.
The return must account for changes since the previous LBTT return and provide details of the incoming tenant. Any additional tax must be paid when the return is submitted, while an overpayment may be reclaimed.
Following the transfer, responsibility for future LBTT obligations normally passes to the incoming tenant. However, the three-year review timetable does not start again. It continues from the effective date of the original lease.
This means an incoming tenant could acquire a lease shortly before its next review return is due. As part of the transaction, agents should help ensure that the parties and their advisers establish:
- the original effective date and next review deadline
- the transaction reference for the original return
- what returns have already been submitted
- whether any tax remains outstanding
- whether the incoming tenant is paying a premium for the assignation.

A return is required when the lease ends
The tenant must also submit a termination return when a notified lease ends. This applies whether it ends early, is renounced, or reaches its natural expiry.
The return is due within 30 days beginning with the day after termination. It updates the tax calculation to reflect the rent actually payable and any other changes since the previous return.
Recalculation may result in further tax being due or a repayment to the tenant. A return must still be submitted where nothing has changed, and no adjustment is required.
