Limits on ADS Repayment: How the FTT Has Clarified 'Disposal of a Dwelling' in the Replacement-of-Main-Residence Test

You paid the 8% Additional Dwelling Supplement on a replacement main residence in 2025, sold the former family home eight months after completion, sent the refund claim to Revenue Scotland, and a refusal letter came back. The rate, the window and the claim form all looked straightforward. The refusal cites Schedule 2A paragraph 8(1)(a) of the Land and Buildings Transaction Tax (Scotland) Act 2013 and says the 'disposal of the ownership of a dwelling' is not satisfied, because the sale was to a wholly-owned company that you still direct. That is the part the headline mechanics never reach: the disposal-limb interpretation the First-tier Tribunal for Scotland has worked through across the last several refund-refusal appeals.

If you have already paid the supplement and face a refusal or part-refusal on the disposal limb, are separating and need the para 9C relief route rather than the standard para 8 refund, are buying jointly and have to handle para 8A spouse aggregation, or are an adviser building the evidence pack at the enquiry stage, this is the detail that decides the claim. The rate, the 36-month replacement window, the £40,000 de-minimis and the standard refund claim route are set out in our LBTT ADS mechanics guide (8% from 5 December 2024); the focus here is where those mechanics break down.

Four limit-cases account for most refusals: the beneficial-ownership-versus-legal-title disposal test under para 8(1)(a); the 36-month window operating in both directions; the 'only or main residence' lookback test under para 8(1)(b); and the joint-buyer aggregation under para 8A together with the separated-spouse relief under para 9C. Each gets the statutory anchor, the FTT-clarified position, and an anonymised worked example.

The disposal-limb interpretation: beneficial ownership, not legal title alone

Schedule 2A paragraph 8(1)(a) requires that you 'have disposed of the ownership of a dwelling' within the 36-month window. The verbatim statutory wording (verified at legislation.gov.uk/asp/2013/11/schedule/2A/paragraph/8 on 2026-05-26) does not say 'disposed of the legal title to a dwelling'. The First-tier Tribunal for Scotland has read 'ownership' as beneficial ownership, supported by a substance-over-form look at the post-transfer pattern of dealings.

The straightforward case is unproblematic. Sell at arm's length to an unconnected third party, complete, take the price and walk away from any continuing interest, and the disposal test is met. Revenue Scotland rarely contests these at enquiry, and the LBTT return amendment route runs cleanly.

The contested cases cluster around four patterns:

• Transfers to a connected party at undervalue. A 'sale' to a parent, sibling or adult child at a price materially below open-market value, especially where you keep occupying or directing the use of the property, raises substance questions. Revenue Scotland will typically ask for arm's-length valuation evidence, the rationale for the discount to market value, and any post-transfer pattern showing you are still involved.
• Transfers to a bare trust where you keep the beneficial interest. Moving legal title to a trustee (a family member or a professional trustee) while you remain the sole beneficiary defeats the disposal test on beneficial-ownership analysis. The legal title has moved; the beneficial ownership has not.
• Sales to a controlled SPV. A sale to a limited company you own and direct (a wholly-owned BTL SPV, an LLP in which you are the sole member) is often treated as a 'disposal' on the basis that the legal title now sits with a separate legal person. The FTT looks at whether you keep practical control and a continuing economic interest; where you do, the refund is at material risk of refusal.
• Disposals that, on closer analysis, leave you with the underlying economic interest. Sale-and-leaseback structures, option arrangements where you retain a buyback right, and conditional sales that have not in fact completed in substance can all defeat the disposal test even where the Disposition has been registered.

So if the refund is the priority, make the disposal genuinely arm's length to an unconnected third party. Where a family-succession or SPV-restructuring objective is what really matters, the ADS refund may have to take second place: a connected-party transfer that keeps the beneficial interest with you produces a refusal at the disposal limb almost every time.

The 36-month window operates in both directions

Schedule 2A paragraph 8(1)(a) reads, in the verbatim statutory text, 'within the period of 36 months beginning with or ending with the effective date of the transaction' (verified at legislation.gov.uk 2026-05-26). The window runs both ways. A lot of competitor pages frame it as forward-only (you have 36 months after the new purchase to sell the former home), which is true as far as it goes but misses the backward-disposal route, and that can cost you a refund you are actually entitled to.

The backward route works like this. If you sold a former main residence up to 36 months before completing on the new home, and at the effective date of the new purchase you still owned a separate second property (an investment property, an inherited dwelling, a holiday home), you are within scope of the para 8 refund test. The substantive test is the same: the disposed dwelling must have been your only or main residence at some point during the 36 months ending with the effective date of the new transaction, per para 8(1)(b).

The pattern that brings this into play is where you:

• Sold a former main residence in 2023.
• Moved in with family or rented for the next two years.
• Bought a new main residence in 2026 while still owning, separately, a buy-to-let property held since before the previous main-residence sale.

You pay the 8% ADS on the 2026 purchase because you own another dwelling at the effective date. The backward route lets you claim it back: the 2023 sale falls within the 36 months ending with the 2026 effective date, and the 2023 property was your main residence at the point of sale. The bidirectional wording in para 8(1)(a) carries the eligibility, and para 8(1)(b) is satisfied because the disposed dwelling was your main residence inside the 36-month lookback.

Schedule 2A paragraph 8B ('Period for disposing of ownership of dwelling') sets out the machinery for computing the 36-month period, including the day-counting rules at the front and back ends of the window. The 2020 extension from 18 to 36 months (originally a pandemic response under the Coronavirus (Scotland) (No.2) Act 2020, later made permanent) was what opened the longer window; the bidirectional structure has been in the statute since 2016.

The lookback main-residence test under para 8(1)(b): the most common refund-refusal trigger

Paragraph 8(1)(b) requires that the disposed dwelling was your 'only or main residence' at some point during the 36 months ending with the effective date of the new acquisition. It is conjunctive with the disposal test in para 8(1)(a): both have to be satisfied for the refund to be available. Pass the forward-disposal test but fail the lookback main-residence test and you are refused.

This lookback failure is the single most common refund refusal in Revenue Scotland enquiries. The shape of it: you moved out of a former main residence more than 36 months before the new purchase, let it as a buy-to-let in the meantime, then sold it within the forward window after the new purchase. The forward-disposal element is satisfied. The lookback main-residence element fails, because by the time the lookback opens (36 months before the new effective date), you are no longer living there as your only or main residence.

If you are in this position, the ways out are limited:

• Document any main-residence period inside the lookback. If you went back to the property briefly inside the lookback window (say you let it for the first two years after moving out, then lived there again as your main residence for six months before the final sale), main-residence status during that six-month period inside the lookback can satisfy para 8(1)(b). The evidence pack needs to support genuine occupation (council tax records, electoral roll, utility records, GP registration), not nominal short-term residence.
• Para 8A joint-buyer analysis where it applies. If you held the property jointly with a spouse, civil partner or cohabitant whose main-residence pattern differs from yours, the para 8A joint-buyer aggregation may let you rely on the co-owner's main-residence history within the lookback.
• Reframe the claim under a different head where you can. If your circumstances fit a different relief (para 9C separated-spouse, the s.108 linked-transaction route for staged acquisitions, the bare-trust look-through under Sch 18 Part 3), a para 8 refusal may still be defensible under a different limb.

The lookback test is how Revenue Scotland controls refund eligibility on long-term-let properties. The policy intent is that the ADS refund is for buyers genuinely replacing a main residence, not for someone liquidating a long-term BTL portfolio who happens to be making a main-residence move at the same time.

The para 8A joint-buyer extension and the para 9C separated-spouse relief

Schedule 2A paragraph 8A operates the refund route where two joint buyers (married, civil-partnered or cohabiting) are replacing a shared main residence. It aggregates both buyers' disposals for the para 8 test, mirroring the purchase-side aggregation under para 5(2). Where each of you held a beneficial interest in the former main residence and each of you disposes of your respective interest within the 36-month window, para 8A runs cleanly.

The complication is the separating-spouse case, where only one of the two former joint buyers disposes of their interest (usually because the other spouse stays in the former family home pending the financial-remedies order). Para 8A may not fully apply there, and the analysis shifts to para 9C.

Schedule 2A paragraph 9C, headed 'Relief for separated spouses and civil partners retaining interest in former main residence' (verified at legislation.gov.uk/asp/2013/11/schedule/2A/paragraph/9C on 2026-05-26), is the discrete separated-spouse relief route. If you are separating, retain an interest in the former main residence pending the financial-remedies order, and buy a new main residence in your own name, the ADS position on the new purchase is governed by para 9C, not the standard para 8 refund. Para 9C is a relief on the new purchase: where its conditions are met, the ADS is not charged in the first place, rather than charged and then refunded after disposal.

The para 9C conditions, in practical terms, are: genuine separation (not a contrived separation for tax purposes); an intention that the separation be permanent, or formal proceedings already in train; the new dwelling acquired as your only or main residence; and the retained interest in the former main residence held pending financial-remedies resolution. You claim it on the LBTT return for the new purchase, not via a post-completion refund.

How para 8A and para 9C interact is, in practice, a sequencing question. If you are separating and have not yet bought the new home, claim para 9C relief on the new acquisition so no ADS is paid in the first place. If you have already paid ADS on the new purchase before anyone looked at para 9C, amend the LBTT return on para 9C grounds to claim the relief retrospectively, with the ADS originally paid refunded.

The Revenue Scotland evidence pack expectations on disposal-limb claims

On ADS refund claims, especially where the disposal involved any connected-party or SPV-controlled element, Revenue Scotland presses hard on the substance of the disposal and on the lookback main-residence evidence. The pack to assemble before any enquiry covers:

• The Disposition or settlement of sale of the disposed dwelling. Date, price, identity of buyer, and (for arm's-length sales) the marketing history and the agency contract. For private sales without an estate agent, contemporaneous evidence of how the buyer was found and how the price was agreed.
• The original LBTT return for the new acquisition showing ADS paid. The Revenue Scotland reference number for the original return, the calculation showing ADS at 8% on the relevant consideration, and the date of payment.
• Main-residence evidence for the disposed property within the 36-month lookback. Council tax records showing your occupation status, electoral roll registration, utility bills in your name across the lookback period, GP registration history, employer correspondence to the address, bank statements addressed to the property, and any contemporaneous documentation supporting genuine main-residence occupation rather than nominal residence.
• For connected-party or below-market disposals. Independent valuation evidence as at the disposal date, the rationale for any discount to market value, any contemporaneous family-arrangement documentation explaining the non-arm's-length features, and evidence of the post-transfer pattern of dealings (who occupies the property afterwards, who pays the council tax, who collects any rental income).
• For separated-spouse claims under para 9C. The financial-remedies order or contemporaneous separation agreement, evidence that the separation is permanent or in formal proceedings (the divorce petition, the family-law solicitor's instructions, the parties' contemporaneous correspondence), and evidence that the new dwelling is your only or main residence.

Assemble the pack at the claim stage, not the enquiry stage. Revenue Scotland's review and enquiry process moves faster than HMRC's equivalent, and the 30-day appeal windows are enforced strictly. A claim filed with the full supporting evidence, rather than a bare claim with documents to follow, tends to clear cleanly without an enquiry.

The Revenue Scotland review and FTT appeal route on refusal

If Revenue Scotland refuses or part-refuses your refund claim, the challenge runs in three stages.

First, request a review by Revenue Scotland under LBTT(S)A 2013 s.65. An officer who was not involved in the original decision reconsiders whether it was correct on the evidence and the statute. You must request the review within 30 days of the decision being appealed, and the review decision is normally issued within 45 days of the request (longer in complex cases).

Second, on an adverse review decision, appeal to the First-tier Tribunal for Scotland (Tax Chamber) under the Tax Collection and Management (Scotland) Act 2014 ss.233-243. The 30-day appeal window from the review decision is strict. The Tribunal hears evidence (typically your contemporaneous documentation, the Revenue Scotland enquiry correspondence and any expert valuation evidence) and issues a written decision. The FTT (Tax Chamber Scotland) decision database, accessible through the Scottish Courts and Tribunals service, is the authoritative source for the case-law line on disposal-limb interpretation.

Third, on an adverse FTT decision, appeal to the Upper Tribunal for Scotland on a point of law only. From there, onward appeal goes to the Inner House of the Court of Session and ultimately (in exceptional cases) to the UK Supreme Court. The disposal-limb case law has, so far, mostly been settled at FTT (Tax Chamber Scotland) level; Upper Tribunal authorities are correspondingly thinner on the ADS-specific points but heavier on the cross-cutting administrative-law and substance-over-form principles.

Three anonymised worked examples

Worked example 1: clean forward-window disposal

Buyer J completes on a £420,000 replacement main residence in Edinburgh on 15 February 2025. ADS at 8% on £420,000 is £33,600, paid on top of standard LBTT on the same return. The former main residence in Aberdeen (held since 2015, lived in as main residence until November 2024, then briefly let for three months pending sale) sells to an unconnected buyer on 22 May 2025, 97 days after the new purchase.

The para 8(1)(a) disposal test is satisfied: the 22 May 2025 sale falls within the forward 36-month window beginning the day after the new acquisition's effective date. The para 8(1)(b) lookback test is satisfied: the Aberdeen property was Buyer J's main residence at the November 2024 point inside the 36-month lookback ending 15 February 2025. The sale was at arm's length to an unconnected buyer, so no beneficial-ownership question arises.

Result: ADS of £33,600 refunded. The claim goes in by amendment of the original Edinburgh LBTT return under the standard amendment route, within 12 months of the return filing date. Evidence pack: the Aberdeen Disposition of sale, the original Edinburgh LBTT return, and council-tax and utility records for the Aberdeen property covering October-November 2024.

This is the clean refund pattern: no para 8A or para 9C complication, and the disposal limb and the lookback test both run straightforwardly.

Worked example 2: lookback failure on main-residence test

Buyer K completes on a £540,000 main residence in Glasgow on 1 June 2025. ADS at 8% on £540,000 is £43,200. She had moved out of her former main residence in Stirling in November 2021 (43 months before the Glasgow effective date) and had been letting the Stirling property as a buy-to-let from December 2021 onwards. She sells the Stirling property on 1 September 2025, three months after the Glasgow purchase, comfortably inside the forward window.

The para 8(1)(a) forward-disposal test is satisfied: 1 September 2025 is inside the 36-month window forward of the 1 June 2025 effective date. The para 8(1)(b) lookback test fails: she moved out 43 months before the 1 June 2025 effective date, so during the 36-month lookback ending 1 June 2025 the Stirling property was a buy-to-let, not her only or main residence.

Result: refund refused. The Stirling property was not her only or main residence at any time during the 36 months ending 1 June 2025; it had been a BTL for the entire lookback. The refusal letter would cite para 8(1)(b) as the operative ground.

This is the lookback trap: move out of a former main residence more than 36 months before the new purchase, let it, then sell, and the forward-window disposal alone is not enough. It is the most common refund-refusal pattern in Revenue Scotland enquiries, and if you are in this position you should know at the new-purchase planning stage that the ADS will not be recoverable.

Worked example 3: separated-spouse retained interest, para 9C relief route

Buyers L and M, married, own a family home in Dundee jointly on a 50/50 basis. Buyer L moves out in October 2024 (effective separation date) and buys a new main residence in her own name on 5 January 2025. ADS at 8% on the £380,000 new purchase is £30,400, paid on the original return. Buyer M stays in the Dundee property. The decree of divorce is granted in November 2025, and the financial-remedies order transferring Buyer L's interest in the Dundee property to Buyer M completes in February 2026 (13 months after the new acquisition).

The para 8 standard refund route is awkward here, because Buyer L's 'disposal' of the Dundee interest only crystallises on the February 2026 transfer (inside the forward window from the January 2025 effective date). Across the intervening period, October 2024 to February 2026, she kept a legal and beneficial 50% interest in the former main residence. Under para 9C, the position is governed by separated-spouse relief, not the standard para 8 refund.

Result: para 9C relief operates so that the January 2025 acquisition is treated as not attracting ADS, on the basis of the retained interest in the former main residence and the separation conditions. The relief is claimed by amendment of the LBTT return for the new purchase on para 9C grounds, and the ADS originally paid is refunded as part of the amendment. The evidence pack covers the separation agreement, the divorce petition or financial-remedies application, contemporaneous correspondence supporting permanent separation, and confirmation that the new dwelling is Buyer L's only or main residence.

Para 9C is the safety valve when the standard para 8 mechanics break down in a separating-spouse case. It is a relief on the new purchase, not a deferred refund, so the sequencing of the amendment claim against the divorce timeline matters a great deal. Spot para 9C at the new-purchase planning stage and ADS is not paid in the first place, which is why advice at the separation stage is essential.

Cross-jurisdictional note

All three UK property-transfer-tax jurisdictions (England and Northern Ireland under SDLT, Wales under LTT, Scotland under LBTT) now align at a 36-month replacement-of-main-residence window for the surcharge refund. The differences in surcharge architecture matter if you are buying across the border, but not for the disposal-limb analysis itself. The English route under Finance Act 2003 Schedule 4ZA para 3 has a discretionary HMRC extension power for exceptional circumstances at para 3(7B); the Scottish route under LBTT(S)A 2013 Sch 2A has no directly equivalent statutory extension power. The Welsh LTT higher-rates regime under LTTA 2017 Sch 5 follows broadly similar timing, with the Welsh Revenue Authority administering the equivalent refund route under separate procedural rules.

On the English side, the surcharge refund routes are the FA 2025 s.51 5% surcharge from 31 October 2024, the FA 2003 Sch 4ZA para 3 replacement-of-main-residence refund, and HMRC's discretion under para 3(7B). The beneficial-ownership-versus-legal-title question runs across all three jurisdictions, and the English case law is largely settled around the same substance-over-form analysis.

Where to take advice

The disposal-limb interpretation, the lookback main-residence test and the para 9C separated-spouse relief are the three places where the headline ADS mechanics most often part company with the outcome you expected. Get advice at the planning stage rather than the enquiry stage if any of these are in play: a connected-party or below-market disposal; a former main residence that was let for a substantial period before sale; a separating-spouse situation with a retained interest in the former family home; a controlled SPV or bare-trust transfer dressed up as a disposal; or a backward-disposal claim under the bidirectional para 8(1)(a) window.

Any one of those can turn an 8% supplement you assumed was recoverable into a refusal that is hard to unwind after the fact. If your transaction has any of these features, talk it through before you file, not after Revenue Scotland has written back. We help Scottish buyers and their advisers get the framing right at the point it still changes the answer.
