Revenue Scotland Updates on LBTT Changes and Additional Dwelling Supplement Rates

Revenue Scotland LBTT updates: key changes and timing points

Revenue Scotland’s LBTT updates page is a timeline of tax and administrative changes rather than one single rule. The main point is that Scottish property tax treatment often depends on when the contract was entered into and when the transaction became effective, especially for the Additional Dwelling Supplement, first-time buyer relief, and claims linked to replacing a main residence.

• ADS rates changed over time: 4% was the earlier rate, 6% applied to transactions entered into on or after 16 December 2022, and 8% applies to transactions entered into on or after 5 December 2024.
• The temporary residential nil-rate band increase introduced in July 2020 ended on 31 March 2021, with the standard nil-rate band returning to £145,000 from 1 April 2021.
• First-time buyer relief can raise the nil-rate band to £175,000 for qualifying buyers, reducing LBTT by up to £600, but only where the contract was entered into on or after 9 February 2018 and the effective date was on or after 30 June 2018.
• Changes to ADS rules for family units and replacement of a main residence took effect from 30 June 2017, and later legislation gave retrospective relief for some earlier transactions.
• When checking an older transaction, you should look at both the contract date and the effective date, and consider whether later retrospective legislation created a repayment claim.
• Some items on the updates page are only operational, such as guidance, technical bulletins, and SETS portal changes, and do not themselves change the law.

Revenue Scotland LBTT updates: what changed and why it matters

This page brings together the main changes and announcements listed on Revenue Scotland’s LBTT updates page. It is not a single legal rule. Instead, it is a timeline of changes to Land and Buildings Transaction Tax in Scotland, especially the Additional Dwelling Supplement, first-time buyer relief, and some administrative updates to Revenue Scotland’s online systems and guidance. The practical value is in identifying which change applied at which time.

What this rule is about

LBTT is Scotland’s tax on land transactions. Over time, the Scottish Government and Revenue Scotland have changed rates, introduced reliefs, amended the Additional Dwelling Supplement rules, and updated the filing system used to submit returns.

The key point is that many LBTT outcomes depend on timing. A transaction can fall under one set of rules or another depending on when the contract was entered into and when the transaction became effective. This updates page shows that clearly.

The main topics covered in the source material are:

• changes to the ADS rate
• the temporary and then restored residential nil-rate band
• the introduction of first-time buyer relief
• changes to ADS rules for family units and replacement of a main residence
• administrative updates, including Revenue Scotland guidance, technical bulletins, and the SETS online portal

What the official source says

The source records the following main updates.

• For transactions entered into on or after 5 December 2024, ADS is charged at 8% of the relevant consideration.
• For transactions entered into on or after 16 December 2022, ADS is charged at 6% of the relevant consideration.
• As noted in January 2021, the temporary increase in the residential LBTT nil-rate band introduced in July 2020 was due to end on 31 March 2021. From 1 April 2021, the residential nil-rate band was to return to £145,000.
• First-time buyer relief continued to apply, effectively increasing the nil-rate band for qualifying first-time buyers to £175,000 and reducing tax by up to £600.
• First-time buyer relief was introduced by the Land and Buildings Transaction Tax (First-Time Buyer Relief) (Scotland) Order 2018. According to the source, it applies only where the contract was entered into on or after 9 February 2018 and the effective date was on or after 30 June 2018.
• The source explains that the relief is not available if the effective date was before 30 June 2018.
• The 2017 Order amended ADS rules on family units and replacing a main residence with effect from 30 June 2017.
• The Land and Buildings Transaction Tax (Relief from Additional Amount) (Scotland) Act 2018 later gave retrospective effect to those changes. The source says this allowed eligible transactions with contracts entered into on or after 28 January 2016 and effective dates on or after 1 April 2016 to claim relief or repayment.
• Revenue Scotland also published technical bulletins, guidance on what counts as a dwelling including caravans, and various operational updates to SETS and return forms.

What this means in practice

The practical message is that LBTT is heavily date-sensitive.

If you are checking an older Scottish property transaction, you should not assume today’s rates or rules applied at the time. The correct LBTT position may depend on:

• the contract date
• the effective date
• whether the transaction involved an additional dwelling
• whether the buyer qualified as a first-time buyer
• whether the transaction involved replacing a main residence
• whether special family unit rules affected ADS

For ADS in particular, the source shows three different rate points over time:

• 4% was the rate referred to in the January 2021 update
• 6% applied for transactions entered into on or after 16 December 2022
• 8% applies for transactions entered into on or after 5 December 2024

That matters because even a small percentage change can materially alter the tax due on a residential purchase.

The first-time buyer updates matter for a different reason. They do not create a separate tax regime. Instead, they reduce LBTT for qualifying buyers by effectively extending the nil-rate band from £145,000 to £175,000, with a maximum reduction of £600 according to the source.

The ADS family-unit and main-residence changes matter because they can affect whether ADS was due at all, or whether a repayment later became available. The source makes clear that later legislation gave retrospective effect to earlier changes. That is important because some transactions that did not qualify for relief when they completed could later become eligible for relief or repayment once the retrospective legislation came into force.

How to analyse it

If you are trying to work out the effect of these updates on a transaction, a sensible approach is:

• Identify the tax involved: ordinary residential LBTT, ADS, non-residential LBTT, or a relief.
• Check the contract date.
• Check the effective date of the transaction.
• Match those dates to the relevant update in force at the time.
• For ADS, ask whether the purchase was of an additional dwelling and whether any replacement of a main residence rules might apply.
• For first-time buyer relief, ask whether the statutory qualifying conditions were met and whether both the contract date and effective date fall within the dates given in the source.
• If looking at an older case, ask whether later retrospective legislation changed the position and created a possible repayment claim.
• Separate legal changes from administrative changes. A portal update or revised form may help with filing, but it does not itself change the law.

The source also distinguishes between legislation and guidance. That matters. The legal effect comes from the legislation, such as the 2017 Order, the 2018 Act, and the 2018 first-time buyer relief Order. Revenue Scotland guidance explains how it applies those rules, and system changes make claims and returns possible in practice.

Example

Illustration: suppose a buyer purchased an additional dwelling in Scotland under a contract entered into after 5 December 2024. On the face of the source material, the ADS rate for that transaction would be 8% of the relevant consideration, assuming the transaction otherwise fell within ADS.

By contrast, if another buyer entered into a relevant transaction on 20 December 2022, the source indicates that the ADS rate would be 6% rather than 8%.

A different example is a first-time buyer purchase. If a buyer met the statutory conditions for first-time buyer relief, and the contract was entered into on or after 9 February 2018 with an effective date on or after 30 June 2018, the source says the relief could apply. Its effect would be to increase the nil-rate band from £145,000 to £175,000 for that buyer, reducing LBTT by up to £600.

Why this can be difficult in practice

This area can be awkward for several reasons.

First, the source is an updates page rather than a full statement of the law. It flags changes, but it does not set out all statutory conditions in detail. For example, it tells you that first-time buyer relief exists and gives the key date conditions, but it does not reproduce all qualifying requirements.

Second, timing rules can be easy to misread. The source sometimes refers to transactions “entered into on or after” a date and elsewhere refers to the “effective date”. Those are not always the same thing, and both may matter.

Third, retrospective legislation can change the answer for historic transactions. The ADS changes affecting family units and replacement of a main residence are a good example. A person reviewing an old transaction may need to ask not only what the law said on completion, but also whether later legislation created a right to relief or repayment.

Fourth, not every item on the page is a substantive tax change. Some entries are about system upgrades, payment details, technical bulletins, or corrections to portal balances. Those can be important operationally, but they do not necessarily alter the underlying tax liability.

Key takeaways

• This Revenue Scotland page is mainly a timeline of LBTT changes, not a single rule.
• For ADS and reliefs, the correct answer often depends on both the contract date and the effective date.
• The source shows important changes to ADS rates, first-time buyer relief, and retrospective ADS relief for some family unit and main residence cases.
