LBTT Legal Framework
Land and Buildings Transaction Tax was created by the Land and Buildings Transaction Tax (Scotland) Act 2013 (asp 11), enacted under powers devolved to the Scottish Parliament by the Scotland Act 2012. LBTT replaced UK-wide Stamp Duty Land Tax (SDLT) for all land transactions in Scotland with an effective date on or after 1 April 2015.
The tax is administered by Revenue Scotland, established alongside LBTT as Scotland's first devolved tax authority. Revenue Scotland operates independently of HMRC and is accountable to the Scottish Parliament. Tax powers, penalties and dispute resolution are governed by the Revenue Scotland and Tax Powers Act 2014 (RSTPA 2014).

Additional Dwelling Supplement introduced at 3%
Temporary COVID nil-rate band increase to £250,000 (15 Jul 2020 to 31 Mar 2021)
ADS refund window extended from 18 to 36 months (1 Apr); ADS raised to 8% (5 Dec)
ADS Rate History
The Additional Dwelling Supplement has been raised three times since its 2016 introduction, more than doubling from 3% to 8%. Each increase was announced as part of a Scottish Budget and took effect on the date below (with transitional rules for contracts exchanged before the announcement).
ADS Rate Timeline
| Effective Date | ADS Rate | Context |
|---|---|---|
| 1 April 2016 | 3% | ADS introduced alongside UK-wide additional dwelling surcharge |
| 25 January 2019 | 4% | First increase, as part of Scottish Budget 2019-20 |
| 16 December 2022 | 6% | Raised in Scottish Budget 2023-24 (Emergency Budget) |
| 5 December 2024 | 8% | Raised in Scottish Budget 2025-26; now the highest additional-dwelling rate in the UK |
Transitional rules
Where the effective date falls on or after an ADS increase, but the contract was entered into before the announcement date, the previous ADS rate applies. Always check the contract exchange date against the announcement date.
Filing LBTT: Step by Step
LBTT returns are filed electronically through Revenue Scotland's SETS (Scottish Electronic Tax System) portal. Your solicitor normally handles this as part of conveyancing, but you as the buyer are legally responsible for ensuring the return is filed and paid on time.
Transaction completes
The effective date (usually the date of settlement/completion) starts the 30-day countdown.
Solicitor prepares return
Your solicitor calculates the LBTT due based on the purchase price, buyer type, and any reliefs claimed.
Return submitted via SETS
The return must be submitted to Revenue Scotland within 30 days. Agents and solicitors log in to SETS. Unrepresented taxpayers can also submit directly.
Payment made
LBTT must be paid at the same time. Payment methods: BACS, CHAPS, or faster payment. Cheques are no longer accepted.
Acknowledgement received
Revenue Scotland issues a submission receipt needed by Registers of Scotland to register the title transfer.
Who must file?
- Any purchase with consideration over £40,000
- Even if no LBTT is due (e.g. purchase under £145,000)
- Lease transactions above the notification threshold
- Both represented (via solicitor) and unrepresented buyers
Key deadlines
- 30 days: submit return + pay tax
- 12 months: amend a filed return
- 36 months: claim ADS refund (from April 2024)
- Contact: [email protected]
LBTT Penalties
Revenue Scotland can impose penalties for late filing, late payment, or inaccurate returns. The penalty regime is set out in the Revenue Scotland and Tax Powers Act 2014 (RSTPA).
Late Submission
| Return not received by 30-day deadline | £100 |
| 3+ months after deadline | £10 per day (up to 90 days) |
| 6+ months after deadline | £300 or 5% of unpaid tax (whichever is greater) |
| 12+ months after deadline | Another £300 or 5% of unpaid tax |
Late Payment
| Tax not paid within 30 days of due date | 5% of outstanding tax |
| 5 months after first late payment penalty | Another 5% of outstanding tax |
| 11 months after first late payment penalty | Another 5% of outstanding tax |
Disputes and appeals
If you disagree with a penalty, you can request a review by Revenue Scotland or appeal directly to the Scottish Tribunals. You do not need to request a review before appealing.
ADS Refund: Complete Claim Guide
If you bought a new main residence and paid ADS because you had not yet sold your previous home, you can claim a full refund once the previous property is sold. The refund window is 36 months from the date of purchase for transactions from 1 April 2024 onwards (18 months for earlier transactions).
Eligibility
You CAN claim if:
- Previous main residence sold within 36 months (18 months pre-April 2024)
- The sold property was your main residence at some point in the relevant period before buying the new one
- You now live in the new property as your main residence
- For joint buyers from 1 April 2024, only one buyer needs to have sold a previous main residence (both must live in the new one)
You CANNOT claim if:
- Previous property not sold within the refund window
- New property is not your main residence
- The purchase was by a company (different rules apply)
- Revenue Scotland does not consider exceptional circumstances for missed deadlines
How to claim
1. Existing agent (same solicitor who filed the original return)
Amend the original LBTT return in the SETS portal. Navigate to Find Returns, select the return, click Amend, and complete the ADS section. Evidence must be uploaded before submission.
2. New agent (different solicitor)
Complete form RS-0005 (ADS Repayment Claim Form) and email to [email protected] with supporting evidence.
3. Taxpayer (claiming directly, no agent)
Use Revenue Scotland's online repayment claims portal. Paper claims are no longer accepted.
Evidence required
| Evidence Type | Accepted Documents |
|---|---|
| Proof of sale | Copy of disposition of sale, Land Registration documents, or a letter from your solicitor stating the date of sale |
| Proof of residence | Council tax bill, utility bill, or bank statement showing the property was your main residence |
Processing time: Revenue Scotland aims to process claims within 10 working days. Complex claims may take longer. Interest is paid on approved refunds at the higher of 0.5% per annum or the Bank of England base rate.
Common LBTT Pitfalls
These are the mistakes and edge cases that catch buyers, solicitors and investors most frequently. Most are structural differences from SDLT that English buyers (or English-trained solicitors) may not expect.
ADS applies on the FULL price, not band-by-band
Unlike England's 5% surcharge which is added to each marginal band, Scotland's 8% ADS is charged on the entire purchase price as a flat percentage. On a £300,000 property, ADS alone is £24,000.
Companies always pay ADS
Any purchase of a residential dwelling by a company (or certain trusts) with a consideration of £40,000 or more triggers ADS, regardless of whether it is the company's first property.
£40,000 threshold catches small transactions
ADS applies to any additional residential property purchase over £40,000. You must also submit an LBTT return for any property purchase over £40,000, even if no LBTT is due.
Joint buyers: one existing property = ADS for all
If any buyer in a joint purchase already owns a residential property (anywhere in the world), the ADS applies to the entire transaction. For spouses and civil partners, properties owned by either party count.
Linked transactions can increase your LBTT
If you buy multiple properties from the same seller (or connected parties) in linked transactions, the consideration is aggregated. This can push you into a higher LBTT band.
30-day deadline is strict
The 30-day filing and payment deadline runs from the effective date (usually completion). There is no grace period. A return filed on day 31 attracts the £100 penalty automatically.
Pre-2015 missives may still require SDLT
If formal letters (missives) were exchanged before 1 May 2012 but the effective date was on or after 1 April 2015, the transaction may be subject to SDLT rather than LBTT under transitional rules.

Frequently Asked Questions
How long do I have to file an LBTT return?
30 days from the effective date (usually the completion date). This is longer than England's 14-day SDLT deadline, but still strict. Late filing attracts an automatic £100 penalty.
What is the SETS portal?
SETS (Scottish Electronic Tax System) is Revenue Scotland's online platform for submitting LBTT returns, paying tax, amending returns, and claiming ADS refunds. Solicitors and agents must register for access.
Can I amend an LBTT return after filing?
Yes, within 12 months of the filing date. Amendments are made through the SETS portal. Common reasons include ADS refund claims, price adjustments, and correction of errors.
How long does an ADS refund take?
Revenue Scotland targets 10 working days from receipt of all required information. Complex claims or those with incomplete evidence may take longer. Interest is paid on approved refunds.
What if I miss the 36-month ADS refund deadline?
Revenue Scotland has stated it cannot consider exceptional circumstances for missed ADS refund deadlines. If you miss the window, the ADS cannot be reclaimed.
Do I file with HMRC or Revenue Scotland?
Revenue Scotland for all Scottish property transactions from 1 April 2015 onwards. HMRC has no involvement in LBTT.
