Multiple Dwellings Relief was, until 1 June 2024, a single United Kingdom-wide concept: a relief that allowed the property-transaction tax on a transaction involving two or more dwellings to be computed by reference to the average consideration per dwelling, rather than on the aggregate. The Finance (No.2) Act 2024 s.7 abolished the SDLT version of the relief, with effect for land transactions with an effective date on or after 1 June 2024. The Scottish and Welsh equivalents survived: LBTT MDR in Scotland under LBTT(S)A 2013 Schedule 5; LTT MDR in Wales under LTTA 2017 Schedule 13. The relief now means three different things in the United Kingdom, and the operational question for any acquirer is which jurisdiction's tax applies to the transaction. This page is the canonical three-jurisdiction hub: it sets out the diagnostic, the integrated current statutory state across all three reliefs, and the routing into the operational page for each jurisdiction.

The diagnostic: which jurisdiction's tax applies?

The starting question is jurisdictional, not statutory. The diagnostic test is location of the property. Property in England or Northern Ireland sits in the SDLT regime, where MDR has been abolished for transactions with an effective date on or after 1 June 2024 (subject to the narrow s.7(4) transitional carve-outs). Property in Scotland sits in the LBTT regime, where MDR remains live under Schedule 5. Property in Wales sits in the LTT regime, where MDR remains live under Schedule 13.

For SDLT transactions the second-order question is the effective date. If the effective date is on or after 1 June 2024, the post-abolition position applies (subject to the s.7(4) carve-outs). If the effective date is before 1 June 2024, the pre-abolition MDR mechanic under FA 2003 Schedule 6B continues to apply. The effective date is determined under FA 2003 s.119 as the earlier of completion or substantial performance under s.44. For LBTT and LTT transactions the effective-date question is not load-bearing for relief availability: the relief is in force at the date of writing and the in-jurisdiction in-scope test under the relevant schedule is the operative question.

The SDLT position: abolished from 1 June 2024 (with narrow transitional carve-outs)

Finance (No.2) Act 2024 s.7 repealed FA 2003 Schedule 6B (the SDLT MDR schedule). The repeal commences for land transactions with an effective date on or after 1 June 2024 (s.7(3)). Verbatim s.7 text at legislation.gov.uk/ukpga/2024/12/section/7 (verified 26 May 2026). The November 2023 HMRC consultation that preceded the abolition concluded that MDR was no longer meeting its policy objective of supporting the supply of new dwellings, and that a majority of claims surveyed were abusive or attempted on transactions outside the policy intent (typically claims by individual buyers on single-dwelling acquisitions characterising annexes or sub-divisions as additional dwellings to manufacture an MDR claim).

The abolition is forward-looking. Two transitional carve-outs preserve MDR availability for narrow pre-commencement contractual positions under s.7(4):

  • s.7(4)(a) substantial-performance carve-out: the transaction is effected in pursuance of a contract entered into and substantially performed before 1 June 2024. Substantial performance is determined under FA 2003 s.44 (possession of the whole or substantially the whole of the subject matter; or payment of a substantial amount of the consideration, HMRC interpretation approximately 90%).
  • s.7(4)(b) pre-6-March-2024 contract carve-out: the transaction is effected in pursuance of a contract entered into on or before 6 March 2024 and is not 'excluded'. 'Excluded' under s.7(5) covers post-6-March-2024 variations of the contract, post-6-March-2024 option exercises, and certain subsequent assignments.

The s.7(6) to (8) linked-transactions architecture handles the anti-forestalling angle: where an MDR claim is made on a pre-commencement leg of a linked-transactions set, pre-commencement and post-commencement linked transactions are de-linked so that the post-commencement legs sit in the post-abolition architecture without artificial MDR-style aggregation. The architecture mirrors the typical SDLT anti-forestalling pattern (see also FA 2003 s.75A).

For acquirers caught by the carve-outs, the pre-abolition MDR mechanic under FA 2003 Schedule 6B continues to apply: average-consideration banding (paragraphs 4 and 5), the "dwelling" definition (paragraph 3), the claim mechanic (paragraph 2), and the later-event withdrawal at paragraph 5A. The pre-abolition snapshot at legislation.gov.uk/ukpga/2003/14/schedule/6B/2024-05-31 is the reference text for transitional-cohort SDLT MDR claims. For the historical pre-abolition statutory walk-through, see our historical SDLT MDR eligibility and benefits page.

The Scottish position: LBTT MDR remains live under Schedule 5

LBTT MDR sits at Schedule 5 of LBTT(S)A 2013 asp 11. The schedule was commenced 1 April 2015 by SSI 2015/108 and remains in force with no outstanding effects as at 26 May 2026 (verified at legislation.gov.uk/asp/2013/11/schedule/5). The Scottish Parliament has not legislated an MDR repeal and no abolition consultation has been published by the Scottish Government. LBTT is a devolved tax administered by Revenue Scotland under separate Scottish-Parliament statute; the UK Parliament's repeal of SDLT MDR has no direct effect on the Scottish position.

The Schedule 5 mechanic mirrors the pre-abolition SDLT MDR architecture in broad outline. Paragraph 4 covers a single transaction with two or more dwellings as main subject matter; paragraph 5 covers a single-dwelling transaction linked to at least one other dwelling transaction; paragraph 6 sets the excluded transactions (group / reconstruction or acquisition / charities / crofting community right to buy); paragraph 7 attributes the consideration between dwellings and remaining property; paragraphs 11 and 12 set the minimum-prescribed-amount floor under Scottish Statutory Instrument; paragraph 13 sets the rate-computation mechanic (average-consideration banding through the LBTT residential rates).

The Additional Dwelling Supplement under Schedule 2A applies in addition to LBTT and is not reduced by MDR. The current ADS rate is 8% of the relevant consideration under Schedule 2A paragraph 4(2), commenced 5 December 2024 by SSI 2024/367 (verified at legislation.gov.uk/asp/2013/11/schedule/2A). The Scottish portfolio acquirer therefore models the LBTT outcome as MDR-reduced base LBTT plus 8% ADS on the full dwelling consideration. For the full Scottish operational mechanic, the linked-transactions paragraph 5 architecture, the minimum-floor verification, and three worked Scottish examples (a single-vendor 4-flat Edinburgh acquisition, a cross-border Manchester-vs-Edinburgh comparator, and an Aberdeen / Stirling / Inverness linked chain), see our Scottish LBTT MDR operational page.

The Welsh position: LTT MDR remains live under Schedule 13, with two recent refinements

LTT MDR sits at Schedule 13 of LTTA 2017 anaw 1. The schedule has been in force from 1 April 2018 and remains live (verified at legislation.gov.uk/anaw/2017/1/schedule/13). The Welsh Government has not announced an MDR abolition consultation mirroring the UK SDLT abolition. Two recent statutory refinements update the operative Welsh architecture and should be on the radar of any practitioner advising on a Welsh LTT MDR claim.

  • New paragraph 7A 'Subsidiary dwellings' (effective 7 February 2025 by SI 2025/119): a qualifying dwelling and a purchased dwelling (or more than one) that is subsidiary to it are treated as if they were an interest in a single dwelling for MDR purposes. The amendment is an anti-fragmentation refinement: it prevents a buyer from claiming MDR on a transaction architected to count a granny annexe, a coach-house, or an analogous subsidiary unit as a separate dwelling so as to manufacture or inflate the dwelling-count. The verbatim core wording is at SI 2025/119 (the Land Transaction Tax (Modification of Relief for Acquisitions Involving Multiple Dwellings) (Wales) Regulations 2025).
  • Substituted paragraph 6(2) minimum floor at 3% (effective 13 February 2026 by Welsh Regulations): the minimum-prescribed-amount floor on the Welsh MDR claim was substituted to 3% effective 13 February 2026. The floor prevents the average-banding mechanic from reducing the LTT below a prescribed minimum on very-low-average-consideration computations; the new 3% figure materially limits how low the per-dwelling averaging can drive the Welsh tax line on lower-priced portfolios. Verify the exact Welsh Regulations SI at the date of any transaction.

The two refinements have not been picked up consistently across competitor commentary; many existing online sources describe the pre-amendment Welsh architecture. For the full Welsh operational mechanic including the post-amendment Schedule 13 walk-through, the Welsh LTT higher-rates interaction under LTTA 2017 Schedule 5, and Welsh-side worked examples, see our Welsh LTT MDR survives page.

The three surviving SDLT alternatives for English and Northern Irish portfolio acquirers

The SDLT MDR abolition removes the most-commonly-used relief for English and Northern Irish portfolio acquisitions. Three other SDLT routes survive and remain available where their statutory criteria are met on the deal substance.

  • FA 2003 s.116(7) automatic non-residential deeming: where a transaction involves the acquisition of 6 or more dwellings in a single transaction, the transaction is treated as non-residential for SDLT purposes. The deeming is statutory and automatic; no claim is required. Non-residential SDLT rates under FA 2003 s.55 Table B are typically materially lower than residential rates plus the 5% additional-dwellings surcharge under Schedule 4ZA. The route is the workhorse surviving alternative for the 6-or-more-dwellings portfolio acquirer. Verbatim s.116 at legislation.gov.uk/ukpga/2003/14/section/116.
  • FA 2003 Schedule 15 paragraph 10 partnership Sum of the Lower Proportions route: for transactions that constitute a transfer of a chargeable interest from a partnership to a person who is or has been a partner (or a connected person), SDLT is computed by reference to the Sum of the Lower Proportions formula. The route requires a genuine pre-existing partnership with substance (not a shell formed for the transaction), and it is targeted at intra-partnership transfers, incorporations of partnerships, and partnership reorganisations. Verbatim Schedule 15 at legislation.gov.uk/ukpga/2003/14/schedule/15.
  • FA 2003 s.45 sub-sale relief: where a buyer (B) contracts to acquire from a seller (A), and B then sub-sells to a third party (C) before completion, s.45 substitutes the A-to-C consideration for the A-to-B consideration in the SDLT computation, with B treated as having entered into the transaction at the substituted consideration. The route is narrow and is targeted at genuine pre-completion onward-sale arrangements; it is not a general planning route. Verbatim s.45 at legislation.gov.uk/ukpga/2003/14/section/45.

None of the three replaces MDR in scope. A 4-dwelling acquisition by a single buyer does not engage s.116(7) (which requires 6 or more); it does not engage Schedule 15 SLP (which requires a partnership transfer); and it does not engage s.45 (which requires a sub-sale architecture). For 4-dwelling acquisitions in England and Northern Ireland after 1 June 2024, the post-abolition SDLT calculation (residential bands plus 5% surcharge) is typically the operative figure. For the full SDLT post-abolition operational depth including the surviving-alternatives mechanics, see our SDLT MDR abolition transitional rules page.

Worked example 1: three-jurisdiction comparator at £2 million / 4 dwellings

A property investor ("Acquirer M1") is modelling acquisitions of 4 flats at total consideration £2 million (average £500,000 per dwelling) in three hypothetical jurisdictions: England, Scotland, Wales. Acquirer M1 already owns residential property in each jurisdiction, so the additional-dwellings supplement applies in each case.

England (SDLT, MDR abolished): Full £2 million rated through SDLT residential bands plus the 5% additional-dwellings surcharge under Schedule 4ZA Table A (combined-rate bands set by FA 2025 s.51 commenced 31 October 2024). Approximate SDLT (verify against gov.uk SDLT calculator at write): in the order of £253,500.

Scotland (LBTT, MDR live): £500,000 per-dwelling figure rated through LBTT residential bands. Approximate per-dwelling LBTT at £500k in the order of £23,350 (verify at write); multiplied by 4 dwellings approximately £93,400. Plus ADS at 8% × £2,000,000 = £160,000. Total approximately £253,400 (broadly equivalent to the English outcome under this dwelling-count and consideration mix; the LBTT base rate after MDR is lower than the English equivalent but the ADS uplift at 8% is higher than the English 5% surcharge).

Wales (LTT, MDR live): £500,000 per-dwelling figure rated through LTT residential bands; the minimum-floor check at Schedule 13 paragraph 6(2) substituted to 3% effective 13 February 2026 applies. Plus the Welsh LTT higher-rates for additional dwellings under LTTA 2017 Schedule 5. Approximate figures pending band verification at write.

Operational point: the three jurisdictions can deliver materially different acquisition-tax outcomes at the same headline consideration. The England-vs-Scotland comparison above is illustratively close at 4 dwellings × £500k; the differential expands or contracts at different dwelling counts and consideration tiers (at higher dwelling counts the s.116(7) route may apply on the English leg; at lower per-dwelling consideration the Welsh floor at 3% may bite). RUN session verifies all rate-by-reference figures at write against legislation.gov.uk plus HMRC / Revenue Scotland / WRA published rate-tables.

Worked example 2: transitional cohort, SDLT MDR survives on post-abolition completion

A buy-to-let landlord ("Acquirer M2") contracted to buy a block of 4 flats in England on 14 February 2024. The contract included a long-stop completion in October 2025 to allow vendor refurbishment. Acquirer M2 paid the deposit at exchange and took possession of one flat on 20 May 2024 for refurbishment supervision (an event satisfying substantial performance under FA 2003 s.44).

Test: the effective date for SDLT under FA 2003 s.119 is the earlier of completion (October 2025) or substantial performance (20 May 2024). The substantial-performance date of 20 May 2024 precedes 1 June 2024.

Result: SDLT MDR remains claimable. F(No.2)A 2024 s.7(4)(a) carve-out applies (the contract was entered into and substantially performed before 1 June 2024). The anti-forestalling architecture under s.7(5) does not bite, because the underlying contract is pre-6-March-2024 and has not been varied post-6-March-2024.

Operational point: Acquirer M2's SDLT return reflects the 20 May 2024 effective date, not the October 2025 completion date. MDR is computed on the average-consideration-per-dwelling basis under the (now-repealed-for-non-transitional-cases) FA 2003 Schedule 6B. Evidence pack required: the contract dated 14 February 2024; deposit receipt; possession evidence (key handover documentation, refurbishment supervision authorisation, contemporaneous correspondence showing the buyer's exercise of dominion over the unit). The post-abolition position does not apply to this transaction set by virtue of the s.7(4)(a) carve-out.

Worked example 3: post-abolition surviving SDLT alternative, s.116(7) 6-or-more-dwellings route

A portfolio landlord ("Acquirer M3") agrees to acquire 7 buy-to-let dwellings from a single vendor in England in a single transaction. Contract dated October 2025; completion January 2026. Total consideration £2.45 million (average £350,000 per dwelling). No partnership; not connected with vendor.

Test: the transaction involves the acquisition of 6 or more dwellings in a single transaction. FA 2003 s.116(7) automatic non-residential deeming applies; no claim required.

Calculation: non-residential SDLT bands under FA 2003 s.55 Table B (verify current rates at write): 0% on £150,000 = £0; 2% on £100,000 (£150k to £250k) = £2,000; 5% on £2.2 million (above £250k) = £110,000. Total non-residential SDLT approximately £112,000.

Comparison: residential rates plus the 5% additional-dwellings surcharge under Schedule 4ZA on £2.45 million would be markedly higher (indicative range £230,000 to £270,000 depending on band interaction; verify against gov.uk SDLT calculator at write). The s.116(7) deeming therefore delivers a material saving on this acquisition versus the residential-rate treatment.

Operational point: s.116(7) is the workhorse post-abolition route for 6-or-more-dwellings English portfolio acquisitions. Evidence pack: vendor sale particulars confirming 7 dwellings; per-dwelling valuation; transaction documents confirming the single-transaction acquisition. Linked-transactions analysis under FA 2003 s.108 may aggregate separate but related contracts so that the 6-dwelling threshold is satisfied on the aggregate even where individual contracts each involve fewer than 6; the linked-transactions discipline is a recognised area of HMRC enquiry focus.

The HMRC enquiry posture on pre-abolition SDLT MDR claims

Pre-1-June-2024 effective-date SDLT MDR claims remain open to enquiry under the standard SDLT enquiry windows. Schedule 24 FA 2007 penalty exposure applies for careless or deliberate inaccuracies on the SDLT return. The standard HMRC attack vectors on MDR claims (carried forward from the pre-abolition enquiry pattern) are: dwelling-count inflation (annexes mischaracterised as separate dwellings, contradicted by the Fiander, Brewer, Doe v HMRC line of First-tier Tribunal and Upper Tribunal authority); partial-occupancy or mixed-use re-characterisation under the Hyman v HMRC line on residential / non-residential characterisation; insufficient evidence of the 'dwelling' definition being met at the effective date.

The documentation discipline for defending an MDR claim (per-dwelling valuation, contemporaneous transaction architecture, MDR election supported by an evidence pack at filing) is the principal defence. For the full historical pre-abolition statutory walk-through and the enquiry-defence architecture, see our historical SDLT MDR eligibility and benefits page.

The cross-border position for portfolio investors with multi-jurisdictional targets

For investors with mixed-jurisdiction targets the post-abolition architecture is asymmetric. An English target has no MDR; a Scottish target has LBTT MDR plus 8% ADS; a Welsh target has LTT MDR plus Welsh higher-rates (with the post-Feb-2025 subsidiary-dwellings rule and the post-Feb-2026 3% minimum floor). The structural consequences for cross-border deals are several:

  • Acquisition ordering: there is no longer a "claim the SDLT relief before it disappears" timing pressure on the English leg, because the relief has already disappeared. The structural pressure now is to model the Scottish and Welsh outcomes accurately at the offer stage and to set the overall acquisition cost against the no-MDR English benchmark.
  • Single-SPV-per-jurisdiction: a cross-border holding structure that aggregates targets does not unlock anything additional on the English leg. Single-SPV-per-jurisdiction structures may now be more efficient than a single combined cross-border structure, because the Scottish and Welsh targets benefit from MDR averaging in isolation.
  • s.116(7) pivot on the English leg: for very large 6-or-more-dwelling acquisitions, the English side can pivot to the FA 2003 s.116(7) automatic non-residential deeming route, which may outperform residential-plus-5%-surcharge but cannot use MDR averaging.
  • Recent Welsh refinements: the Welsh side's post-Feb-2025 subsidiary-dwellings rule and post-Feb-2026 3% minimum floor both affect how a Welsh portfolio is computed and structured; competitor commentary that pre-dates these amendments will under-state the Welsh tax line.

None of these structural questions has a generic answer; modelling at the offer or due-diligence stage against the current rate tables in each jurisdiction is the planning step that captures the asymmetry.

Reform-watch across all three jurisdictions as at 26 May 2026

None of the three jurisdictions has an open MDR reform consultation at the date of this page. The UK Government's November 2023 SDLT MDR consultation concluded in the F(No.2)A 2024 s.7 abolition. The Scottish Government has not announced an LBTT MDR consultation. The Welsh Government's recent activity has been refinement-focused (the February 2025 subsidiary-dwellings clarification and the February 2026 minimum-floor substitution to 3%), suggesting an ongoing operative regime rather than an abolition trajectory.

The picture may change in any future Budget cycle in any of the three jurisdictions. The page does not assert that the surviving reliefs are permanent; it reflects the state of the statute and the published policy as at 26 May 2026. Practitioners should verify the current position against the most recent UK, Scottish and Welsh Budget statements and against any open consultation document at the date of any transaction.

Practical guidance for the current MDR-curious reader

Five planning steps for the current acquirer or adviser arriving at this page from the head-term search:

  1. Identify the property location. The location determines the tax regime (SDLT / LBTT / LTT) and therefore determines whether MDR is available. Mixed-jurisdiction portfolios are modelled jurisdiction by jurisdiction; there is no single combined MDR concept.
  2. For SDLT, run the s.7(4) transitional-cohort screen. Effective date under s.119; substantial-performance test under s.44; pre-6-March-2024 contract test; excluded-transaction screen under s.7(5). The carve-outs preserve MDR for a narrow set of pre-commencement contractual positions; outside the carve-outs the post-abolition SDLT calculation applies.
  3. For LBTT or LTT, run the in-jurisdiction MDR computation. Schedule 5 (Scotland) or Schedule 13 (Wales) average-banding mechanic; in-scope test under the relevant paragraph; minimum-floor check; additional-dwellings supplement layered separately on top.
  4. For English or Northern Irish portfolios above the 6-dwelling threshold, screen for s.116(7). The 6-or-more-dwellings automatic non-residential deeming is the workhorse surviving SDLT alternative; for 7-dwelling or larger acquisitions it is often materially more efficient than residential-plus-5%-surcharge.
  5. For cross-jurisdictional portfolios, model side-by-side at the offer stage. The SDLT-abolition + LBTT-MDR + LTT-MDR side-by-side computation surfaces the cross-border restructuring opportunities and the points at which acquisition ordering or single-SPV-per-jurisdiction structuring should be revisited.
