Abolishment of Multiple Dwelling Relief: What Changed on 1 June 2024 and Who Is Affected

Multiple Dwellings Relief was scrapped for SDLT in England and Northern Ireland on 1 June 2024. Finance (No. 2) Act 2024 section 7 repealed both section 58D and Schedule 6B of FA 2003 in full, with effect for land transactions with an effective date on or after that date. If you have just read a headline saying MDR has been abolished and need a straight answer to what changed, when, who is still inside the transitional protection, and what replaces MDR for a buyer trying to acquire multiple dwellings now, this page is the plain-language on-ramp.

For the full operational architecture (the section 7(5) anti-forestalling rules, the three surviving statutory routes worked through in mechanics terms, and a portfolio-buyer cost comparison), see our dedicated F(No.2)A 2024 s.7 transitional rules page. The Welsh cross-border position survives separately under LTTA 2017 Schedule 13 and is covered at our Welsh LTT MDR survives page. The six-or-more-dwellings deeming that does most of the post-abolition heavy lifting is at our s.116(7) page.

The headline in one paragraph

From 1 June 2024 onwards, a buyer acquiring multiple dwellings in a single transaction (or in linked transactions) cannot compute SDLT on the average consideration per dwelling using the old Schedule 6B mechanic. The buyer instead pays SDLT on the full consideration at the standard residential rates, plus the 5% additional-dwellings surcharge under FA 2003 Schedule 4ZA where it applies. For most small-portfolio buyers (two, three, four, or five dwellings) this is a material increase in SDLT, often more than doubling the figure that MDR would have produced. The exceptions are buyers who can reach the six-or-more-dwellings statutory deeming under FA 2003 section 116(7), buyers who can use the partnership sum-of-lower-proportions architecture under FA 2003 Schedule 15, and buyers who fit a genuine sub-sale arrangement under FA 2003 section 45. Each of these has its own eligibility tests; none is a like-for-like replacement for MDR.

Who is still inside the transitional protection

The Government did not abolish MDR with retroactive effect, and it built two layers of transitional protection into the abolition statute. Section 7(4) of Finance (No. 2) Act 2024 protects two cohorts.

The first cohort is contracts entered into on or before 6 March 2024 (Spring Budget 2024 day). Section 7(4)(b) preserves MDR for these contracts where they run through to completion in the normal course. The protection is conditional: section 7(5) defeats it where the contract has been materially varied after 6 March 2024, where the rights under it have been assigned or transferred after that date, where an option or pre-emption right has been exercised after that date, or where the transaction is effected in pursuance of a sub-sale or further transaction created after that date. The architecture is deliberately broad to stop a buyer with a pre-Budget contract sitting on an option, repricing the deal, or assigning the contract to a new buyer in order to retrofit MDR onto a transaction that should sit on the post-abolition side.

The second cohort is contracts entered into between 7 March and 31 May 2024 inclusive, where substantial performance under FA 2003 section 44 also occurred before 1 June 2024. Section 7(4)(a) preserves MDR for these. Substantial performance is reached when the buyer (or a connected person) takes possession of substantially the whole of the property, when a substantial amount of the consideration (in practice usually 90% or more) is paid, or when the first payment of rent under a lease is made. A buyer who exchanged in April 2024, took possession of the property in mid-May 2024, and completed formally in October 2024 is inside section 7(4)(a) protection. A buyer who exchanged in April 2024 with completion in October 2024 and no early possession, no early substantial payment, and no licence to occupy ahead of completion is outside it.

The effective-date test does the heavy lifting

The transitional analysis turns on the FA 2003 section 119 definition of 'effective date'. Section 119 sets the effective date as the earlier of (a) the date of completion of the land transaction, and (b) the date on which the transaction is substantially performed. A contract dated 14 February 2024 with formal completion on 10 July 2024 has an effective date of either 10 July 2024 (if no substantial performance trigger fell earlier) or the earlier substantial-performance date. If the effective date is on or after 1 June 2024, section 7(3) puts the transaction on the post-abolition side; section 7(4)(a) cannot rescue it because the substantial performance also fell after 1 June 2024. If the effective date is before 1 June 2024 because substantial performance triggered earlier (early possession, early bulk payment, early lease rent), the transaction is on the pre-abolition side and MDR may be available subject to all the other Schedule 6B conditions.

For buyers in the transitional period the documentary timeline matters: key handover correspondence, contractor authorisations, bank payment records, licence-to-occupy agreements, and any record of early occupation. HMRC enquiries on transitional MDR claims after 1 June 2024 will test the substantial-performance question and the evidence has to be there.

The anti-forestalling rule in plain English

The Government anticipated that buyers with pre-Budget contracts would attempt to keep MDR alive by varying, assigning, optioning, or sub-selling the transaction past the abolition. Section 7(5) of Finance (No. 2) Act 2024 catches the four most obvious patterns. A material variation of a pre-6-March-2024 contract after 6 March 2024 defeats the section 7(4)(b) protection. An assignment of the rights under the contract after 6 March 2024 defeats it. The post-6-March-2024 exercise of an option, right of pre-emption, or similar right granted under the contract defeats it. A transaction effected in pursuance of a sub-sale, novation, or further transaction created after 6 March 2024 defeats it. Each of these tests is fact-sensitive and the wording in the contract matters; minor administrative variations that do not affect the consideration or the property identity may not constitute a 'material variation' but the safe assumption is that any post-Budget change to a pre-Budget contract is at risk.

What replaces MDR for a buyer purchasing today

Three statutory routes survived the abolition. Each operates on its own logic.

Route one: the six-or-more-dwellings statutory deeming

FA 2003 section 116(7) reads: 'Where six or more separate dwellings are the subject of a single transaction involving the transfer of a major interest in, or the grant of a lease over, them, then, for the purposes of this Part as it applies in relation to that transaction, those dwellings are treated as not being residential property.' This is statutory deeming, not a relief that requires a claim. The transaction is computed at non-residential SDLT rates under FA 2003 section 55 Table B (top rate 5% above £250,000) with no additional-dwellings surcharge under Schedule 4ZA (the surcharge applies only to residential transactions and section 116(7) takes the dwellings outside the residential category). For a genuine 6-plus-dwelling acquisition this is the workhorse route post-abolition and typically the most SDLT-efficient outcome available.

Route two: the partnership sum-of-lower-proportions

FA 2003 Schedule 15 paragraph 10 sets out the sum-of-lower-proportions (SLP) calculation that applies where a partnership acquires a chargeable interest from a connected person. The SLP mechanic reduces the SDLT base by reference to the buyer-partner's existing interest in the underlying assets; in many genuine partnership transactions the result is a markedly lower SDLT charge than the headline residential rate computation would produce. The architecture is conditional. The partnership must be a genuine pre-existing letting business or property business with operational substance, not a vehicle constructed shortly before the transaction in order to access the SLP route. The connected-person test under FA 2003 Schedule 15 paragraph 39 (incorporating CTA 2010 section 1122 and the partnership-specific extensions) governs which transferors qualify.

Route three: section 45 sub-sale relief

FA 2003 section 45 provides relief from SDLT where, in substance, a pre-completion onward sale takes place such that the original contract is fulfilled by a transfer to a third party rather than to the original buyer. The relief operates by disregarding the original contract for SDLT purposes and recognising only the onward transaction. The provisions were tightened by Finance Act 2013 to defeat tax-driven sub-sale schemes and the current architecture requires the sub-sale to reflect commercial reality. For genuine pre-completion onward-sale arrangements (typically in development contexts) section 45 remains available; for constructed-after-the-fact sub-sales designed to manufacture SDLT relief it does not.

The non-route: mixed-use classification

Claims-firm material continues to promote mixed-use SDLT classification as a workaround for the loss of MDR. For a portfolio of ordinary residential dwellings this argument almost always fails. The leading case is Hyman v HMRC [2022] EWCA Civ 185, in which the Court of Appeal upheld HMRC's residential classification of a property with a sizeable garden and confirmed that the threshold for 'mixed use' under FA 2003 section 116 is materially higher than the lay reader might suppose. A portfolio of buy-to-let houses or flats is residential property; the section 116(7) six-plus-dwellings route is the only statutory mechanism that takes it out of the residential rate architecture, and below the six-dwelling threshold the residential rates apply.

Cross-border: the Welsh and Scottish position

The abolition is SDLT-specific. Wales operates Land Transaction Tax under LTTA 2017, and the Welsh Multiple Dwellings Relief survives at Schedule 13. Buyers of property in Wales on or after 1 June 2024 should compute LTT under the Welsh framework and consult our Welsh LTT MDR page for the mechanics. Scotland operates Land and Buildings Transaction Tax under LBTT(S)A 2013 and the Scottish MDR survives at Schedule 5; the Scottish Parliament has not legislated an MDR repeal at the time of writing, so the Scottish relief remains live. Cross-border portfolio buyers (acquiring property in two or more of the three SDLT-area, LTT-area, and LBTT-area jurisdictions) need separate analyses for each jurisdiction; there is no single relief that operates across all three regimes.

A worked numerical comparison: four dwellings at £1.2 million

Numbers make the cost step-up concrete. Take a buy-to-let buyer who already owns one property and is acquiring a four-flat portfolio for £1.2 million from a single vendor in a single transaction. Average per dwelling is £300,000.

Pre-abolition position (effective date before 1 June 2024 or inside a section 7(4) carve-out). MDR computes SDLT on the average consideration per dwelling multiplied by the number of dwellings. £300,000 at standard residential rates plus the 5% additional-dwellings surcharge gives roughly £17,500 per notional dwelling. Multiplied by four dwellings, the total MDR-mechanic SDLT is approximately £70,000. The minimum 1% rate floor in Schedule 6B does not bite here because the computed rate exceeds 1%. (The exact figure depends on the band-by-band split and the SDLT calculator output; the order of magnitude is firm.)

Post-abolition position (effective date on or after 1 June 2024 with no transitional protection). The buyer pays SDLT on the full £1.2 million at standard residential rates plus the 5% additional-dwellings surcharge across the whole price. The residential bands (zero up to £125,000, 2% on £125,001 to £250,000, 5% on £250,001 to £925,000, 10% on £925,001 to £1.5 million) layered with the 5% surcharge produce a total SDLT charge of approximately £115,000 to £125,000. The exact figure again depends on band interaction; the gov.uk SDLT calculator gives the precise number for any specific deal.

The cost step-up on this four-dwelling deal is therefore in the region of £45,000 to £55,000 of additional SDLT, a 60% to 75% increase on the pre-abolition number. For a five-dwelling deal the gap is wider; for a three-dwelling deal it is narrower in absolute terms but proportionately similar. For a six-or-more-dwelling deal the section 116(7) deeming changes the picture entirely (non-residential rates with no surcharge, typically substantially below both the pre-abolition MDR number and the post-abolition residential-plus-surcharge number).

The four-year enquiry window on pre-abolition claims

For advisers reviewing pre-abolition MDR claims that may still be inside HMRC's enquiry window, the relevant timing is FA 2003 Schedule 10 paragraph 12: HMRC may open an enquiry into an SDLT return at any time within nine months of the filing date, or within four years of the filing date where the taxpayer's behaviour was careless or where the enquiry concerns a chargeable consideration adjustment. Pre-abolition MDR claims filed in 2022 to 2024 may still be inside the four-year careless-behaviour window where HMRC views the claim as outside the policy intent. The original Schedule 6B conditions (the dwelling definition under paragraph 7, the average-consideration calculation, the linked-transactions aggregation, the minimum-dwellings test) all remain testable on enquiry even though the relief is now repealed. A buyer who claimed MDR on a granny-annex argument or a marginal-subdivision argument in 2022 or 2023 is not protected from enquiry by the subsequent abolition; the enquiry tests the position at the original effective date.

Where an enquiry concludes that the original claim was incorrect, the underpaid SDLT becomes payable with interest under FA 2009 section 101 from the original due date. Penalty exposure under FA 2007 Schedule 24 follows the same behaviour-rating ladder as for post-abolition mistakes (reasonable care, careless, deliberate, deliberate-and-concealed) with the unprompted-disclosure reductions available where appropriate.

What this means for a buyer making a decision today

The practical position for a buyer running a portfolio acquisition through diligence in 2026 is this. If the deal includes six or more dwellings in a single transaction (or in linked transactions that aggregate under FA 2003 section 108), the FA 2003 section 116(7) deeming applies automatically and the non-residential SDLT rates are the starting point. If the buyer is a genuine partnership acquiring from a connected vendor, the Schedule 15 sum-of-lower-proportions calculation may produce a markedly lower charge than the headline rates; this requires specialist computation. If the deal involves a genuine pre-completion sub-sale, section 45 can disregard the original contract; this is narrow and rarely relevant outside a development context. Outside these three routes, the realistic position is residential SDLT rates on the full consideration plus the 5% additional-dwellings surcharge where it applies, and the SDLT charge will be materially higher than the MDR-era number would have been.
