The Spring Budget 2024 closed the door on Multiple Dwellings Relief. Finance (No. 2) Act 2024 section 7 repealed both section 58D and Schedule 6B of FA 2003 in full, with effect for land transactions with an effective date on or after 1 June 2024. For SDLT-applicable acquisitions in England and Northern Ireland from that date, the relief that has framed portfolio purchase planning for fifteen years no longer exists. What remains is a narrow transitional protection for pre-existing contracts, a section 7(5) anti-forestalling architecture that catches the most obvious workarounds, and three surviving statutory routes that portfolio buyers reach for in different fact patterns.

This page walks the section 7 mechanics verbatim, the FA 2003 section 119 effective-date analysis that drives the transitional question, the section 7(5) anti-forestalling rule that defeats the most common retrofit attempts, and the three surviving alternatives in operational terms. The cross-border position is set out separately because Multiple Dwellings Relief survives in Wales under LTTA 2017 Schedule 13, and Welsh acquirers reading this page from a UK-wide tax-planning angle need that flagged at the outset.

What F(No.2)A 2024 section 7 actually does

The repeal mechanic is short and unambiguous. Section 7(1) of Finance (No. 2) Act 2024 reads: 'Section 58D of, and Schedule 6B to, FA 2003 (relief for transfers involving multiple dwellings) are repealed.' Section 58D was the gateway provision that admitted a buyer to MDR; Schedule 6B was the operative architecture, setting out the relief computation, the 'dwelling' definition, the minimum-dwellings test, and the average-consideration calculation. Repealing both leaves no residual statutory machinery for new transactions to use.

The commencement language sits in section 7(3): 'The amendments made by this section have effect in relation to land transactions the effective date of which falls on or after 1 June 2024.' The effective-date trigger is critical and worth dwelling on; it determines whether the abolition applies to any particular transaction at all.

The effective-date test under FA 2003 section 119

Effective date for SDLT is defined at FA 2003 section 119. The default rule is that the effective date is the date of completion. The fallback rule is that, where substantial performance under FA 2003 section 44 occurs before completion, substantial performance is the effective date instead. The earlier of the two is what counts.

Section 44 sets out three substantial-performance triggers. The first is the purchaser, or a person connected with the purchaser, taking possession of the whole or substantially the whole of the subject matter of the contract; this captures the buyer who takes the keys, moves contractors in, or otherwise has the property under their control ahead of formal completion. The second is the payment of a substantial amount of the consideration, conventionally read as ninety per cent or more of the total price; this captures the buyer who has paid most of the bill but is waiting on a formal completion mechanic. The third is the first payment of rent under a contract for the grant of a lease; this is the lease-grant trigger.

For most landlord and portfolio-buyer transactions, the practical triggers are possession or substantial payment. The evidence pack matters: contemporaneous records of key handover, possession licences, contractor authorisation, payment receipts, and any correspondence pre-dating 1 June 2024 that confirms beneficial control had passed. Without an evidenced substantial performance pre-1-June-2024, the effective date defaults to completion.

The two-tier transitional architecture

F(No.2)A 2024 section 7(4) and (5) build the transitional protection in two layers. The first layer is at section 7(4)(a): the amendments do not apply where 'the transaction is effected in pursuance of a contract entered into and substantially performed before 1 June 2024'. Substantially performed here is the FA 2003 section 44 concept; the section 7(4)(a) carve-out requires both contract entry and substantial performance to have happened pre-1-June-2024.

The second layer is at section 7(4)(b): the amendments do not apply where 'the transaction is effected in pursuance of a contract entered into on or before 6 March 2024 and is not excluded'. 6 March 2024 was Spring Budget Day 2024, the date on which the MDR abolition was announced. The section 7(4)(b) protection is broader than section 7(4)(a) because it does not require substantial performance before 1 June 2024; a pre-6-March-2024 contract qualifies even where substantial performance and completion both fall after the abolition date. But the protection is conditional on the contract not falling within the section 7(5) exclusions.

Section 7(5) sets out the exclusions that defeat the section 7(4)(b) protection. The four patterns are: a contract variation made after 6 March 2024 that affects the consideration or the property; an assignment of the contract, or a transfer of rights under it, after 6 March 2024; the exercise of an option, right of pre-emption, or similar right after 6 March 2024 in pursuance of which the transaction is effected; and a sub-sale, assignment, or other transaction created after 6 March 2024 in pursuance of which the transaction is effected. The architecture was drafted to stop the most predictable workarounds: pre-Budget options, post-Budget price renegotiation, post-Budget contract assignment, and post-Budget sub-sale chains designed to bring an MDR-tagged deal through completion.

Anti-forestalling in operational terms

The section 7(5) exclusions translate into four practical situations to watch for. The first is a price renegotiation: where a pre-6-March-2024 contract is varied after the Budget to change the consideration (typically downwards in a softening market, occasionally upwards where additional dwellings are added), the section 7(4)(b) protection falls away. A variation that simply moves completion timing, or corrects a clerical reference, will not generally be caught; a variation that touches consideration or the property is the trigger.

The second is an assignment of contractual rights. A pre-Budget contract assigned to a new buyer after 6 March 2024 cannot rely on section 7(4)(b); the eventual transaction will be tested against the post-abolition rates as if the assigned contract had never been pre-Budget. This catches the scenario where Buyer A's pre-Budget acquisition is sold on as a pre-completion package to Buyer B in the period before 1 June 2024.

The third is an option exercise. Pre-Budget option arrangements that allow a buyer to elect into a transaction during a specified window are caught where the option is exercised after 6 March 2024. The underlying contract may have been written before the Budget; the section 7(5) exclusion looks at the exercise date of the option that brings the transaction into being.

The fourth is a sub-sale. Where a pre-Budget contract is brought to completion via a sub-sale chain created after 6 March 2024, the section 7(4)(b) protection is lost. Sub-sales are typically structured under FA 2003 section 45; the section 7(5) anti-forestalling rule operates on the timing of the sub-sale creation, not on the section 45 sub-sale relief mechanic itself.

The surviving alternatives for portfolio buyers

FA 2003 section 116(7): the six-or-more-dwellings statutory deeming

The workhorse post-abolition route for genuine portfolio acquisitions is FA 2003 section 116(7). The verbatim wording at section 116(7) is: '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 buyer's SDLT return simply applies non-residential rates under FA 2003 section 55 Table B; no MDR-style election machinery is involved.

The size of the saving is material. Non-residential SDLT rates run 0% on the first £150,000, 2% on the next £100,000, and 5% above £250,000; the top rate is 5%. Residential rates on a portfolio of the same gross value run up to 12% above £1.5m, with an additional 5% additional-dwellings surcharge layered on top of the residential bands for buy-to-let and second-home acquisitions. On a £2.5m seven-dwelling acquisition, the difference between s.116(7) non-residential treatment and residential plus surcharge can run to around £150,000 of SDLT.

Two structural points sit alongside the deeming. The single-transaction test requires the six-plus dwellings to be acquired in one transaction; separate but linked acquisitions may be aggregated for SDLT purposes under FA 2003 section 108, but the section 116(7) deeming itself looks at the transaction structure. And the 'dwelling' definition follows the conventional SDLT meaning; staff accommodation, separately let HMO bedrooms, and similar marginal-dwelling cases need careful analysis. The dedicated six-dwellings rule page sets out the mechanics in more detail.

FA 2003 Schedule 15 paragraph 10: the partnership sum-of-lower-proportions route

Where the buyer is a partnership and the vendor is connected with the partners, FA 2003 Schedule 15 paragraph 10 applies the sum-of-lower-proportions (SLP) formula, often delivering substantial SDLT savings on transfers between a partnership and its partners or persons connected with them. The mechanic is set out in full at the dedicated Schedule 15 partnership SDLT relief page; the headline architecture is that chargeable consideration is reduced from market value to market value multiplied by (1 minus SLP percentage), so a 100% SLP outcome eliminates the SDLT charge.

For post-abolition planning the Schedule 15 route is genuinely useful where the partnership pre-dates the transaction with substance: SA800 returns filed for the relevant years, partnership bank account in use, joint borrowing on the portfolio, partnership operational practice running through the books. Partnerships constructed shortly before the transaction to access Schedule 15 SLP sit in FA 2003 section 75A anti-avoidance territory and HMRC challenges them routinely. The three-year anti-withdrawal rule at Schedule 15 paragraph 17A then sits across post-transfer governance.

FA 2003 section 45: sub-sale relief in genuine pre-completion onward-sale arrangements

FA 2003 section 45 provides a narrow surviving route for genuine pre-completion onward-sale arrangements: where a buyer contracts to acquire property and, before completion, contracts to sell it on to another party, the original contract is in some circumstances effectively ignored for SDLT and the eventual sub-sale transaction is the SDLT trigger. The sub-sale must reflect commercial reality and the arrangement must satisfy the section 45 conditions; HMRC enquiries on section 45 claims look for documentary evidence of the sub-sale arrangement, separate consideration, and a genuine onward-sale rationale.

Section 45 is not a substitute for MDR planning; it is a structural mechanic for a specific transaction shape (pre-completion onward sale) and will not assist a buyer who actually wants to hold the portfolio. Where the shape fits, section 45 is the surviving route; where it does not, attempting to retrofit section 45 onto an ordinary acquisition is FA 2003 section 75A territory.

The cross-border position: Welsh LTT survives, Scotland never had MDR

Wales operates Land Transaction Tax under Land Transaction Tax and Anti-avoidance of Devolved Taxes (Wales) Act 2017. The Welsh LTT MDR-equivalent is at Schedule 13 LTTA 2017 and is unaffected by F(No.2)A 2024 section 7, which amends FA 2003 only. Welsh LTT MDR remains available for transactions with effective dates on or after 1 June 2024 (and beyond). Buyers acquiring Welsh property should consult the dedicated Welsh LTT Multiple Dwellings Relief page for the calculation mechanics, which differ in detail from the now-repealed SDLT version.

Scotland operates Land and Buildings Transaction Tax under LBTT(S)A 2013 and has never had a Multiple Dwellings Relief equivalent. The Scottish framework relies on the Additional Dwelling Supplement architecture and on LBTT-specific reliefs for portfolio and second-home acquisitions; the abolition of SDLT MDR is therefore neutral for Scottish-property acquisitions. Cross-border portfolios that span England and Scotland (or England and Wales) involve parallel calculations under separate statutes, with separate revenue authorities administering each; the planning question is jurisdiction-by-jurisdiction.

What happens if you incorrectly claim MDR after 1 June 2024

The claim will be disallowed on HMRC enquiry. The post-abolition operational position is that the SDLT return is recomputed at residential rates plus the 5% additional-dwellings surcharge (where applicable), with interest running from the original SDLT payment date under FA 2009 section 101. Penalty exposure under Schedule 24 FA 2007 follows where the inaccuracy was attributable to carelessness or deliberate behaviour by the buyer or their adviser.

The behaviour-rating ladder is set out in Schedule 24 paragraph 4: reasonable care attracts no penalty, careless inaccuracies attract 15% to 30% of the potential lost revenue, deliberate inaccuracies attract 35% to 70%, and deliberate and concealed inaccuracies attract 50% to 100%. Mitigation reductions under Schedule 24 paragraph 9 apply for telling (proactive disclosure), helping (cooperation with the enquiry), and giving (access to records). Unprompted disclosure plus full cooperation moves the penalty floor materially down within each band; prompted disclosure (i.e., where HMRC opened the enquiry first) attracts a higher floor.

Where the inaccuracy is attributable to a company officer (typically a director), Schedule 24 paragraph 19 can shift personal liability to the officer in cases of deliberate inaccuracy. The realistic position post-abolition is that any plausible MDR claim on a post-1-June-2024 transaction will be challenged; the buyer's defensive position turns on the strength of the section 7(4)(a) or section 7(4)(b) transitional case, and on whether the section 7(5) exclusions can be ruled out.

Worked examples

Worked example 1: section 7(4)(a) transitional survives

A buy-to-let landlord ('Acquirer A') contracted to buy a block of four flats on 14 February 2024 with long-stop completion in October 2025. The contract included a £52,000 deposit at exchange (4% of the £1.3m purchase price). Acquirer A took possession of one flat on 20 May 2024 under a licence to occupy, instructed contractors to start refurbishment, and the licence is documented. Completion follows in October 2025.

Effective date analysis: substantial performance under FA 2003 section 44 occurred on 20 May 2024 (possession taken under the licence to occupy; refurbishment supervision begun). 20 May 2024 precedes 1 June 2024. The section 7(4)(a) carve-out applies: the contract was both entered into (14 February 2024) and substantially performed (20 May 2024) before 1 June 2024. MDR remains claimable. The SDLT return reflects 20 May 2024 as the effective date and the MDR calculation runs on the (now-repealed) Schedule 6B mechanic that was in force at that date. Evidence pack: contract dated 14 February 2024; deposit receipt; licence to occupy dated 18 May 2024; contractor instructions dated 21 May 2024; possession correspondence; council tax registration in Acquirer A's name from 20 May 2024.

Worked example 2: section 7(5) anti-forestalling defeats the transitional

A property investor ('Acquirer B') entered into a contract on 4 March 2024 (pre-Budget) to acquire five dwellings for £1.6m. The contract was originally tagged as MDR-eligible. After Spring Budget 2024 (6 March 2024), Acquirer B and the vendor agreed a £150,000 price reduction (cooling market) and varied the contract on 18 April 2024 to reflect the new £1.45m price. Completion follows on 30 September 2024; no pre-1-June-2024 substantial performance.

Effective date: 30 September 2024 (completion). The contract was entered into on 4 March 2024, before the 6 March 2024 cut-off, so section 7(4)(b) is the operative protection. But the 18 April 2024 variation post-dates 6 March 2024 and affects the consideration; section 7(5)(a) excludes the transaction from section 7(4)(b) protection. MDR is not available. The transaction is computed at residential rates plus the 5% additional-dwellings surcharge on the full £1.45m. The s.116(7) six-or-more-dwellings deeming is unavailable (five dwellings only). Schedule 15 SLP is unavailable (Acquirer B is a sole buyer, not a partnership). Section 45 sub-sale is unavailable (no onward sale). The post-abolition SDLT cost falls in full on the buyer; the pre-Budget MDR-tagged exposure assumption has to be written down.

Worked example 3: post-abolition section 116(7) route

A portfolio landlord ('Acquirer C') agrees to acquire seven buy-to-let dwellings from a single corporate vendor in a single transaction. Contract dated 12 October 2025; completion 28 January 2026. Total consideration £2.45m, allocated £350,000 per dwelling. No partnership structure; Acquirer C and the vendor are not connected.

Effective date: 28 January 2026 (completion; no earlier substantial performance). Section 116(7) applies: seven separate dwellings acquired in a single transaction, transferring a major interest. The dwellings are deemed not to be residential property for SDLT rate purposes. Non-residential SDLT bands apply on the full £2.45m: 0% on the first £150,000 = £0; 2% on £150,000-£250,000 = £2,000; 5% on the £2,200,000 above £250,000 = £110,000; total £112,000.

The residential-plus-surcharge comparison on the same £2.45m would have been materially higher (residential top rate of 12% above £1.5m plus the 5% surcharge on the whole consideration), in the region of £230,000-£270,000 of SDLT depending on how the bands and surcharge interact in detail. The saving from section 116(7) treatment is approximately £120,000-£160,000 of SDLT. No claim machinery is needed; the SDLT return simply applies non-residential rates. Evidence pack: vendor sale particulars showing the seven dwellings; valuation per dwelling; transaction documents confirming a single-transaction acquisition; linked-transactions analysis under FA 2003 section 108 if any related contracts sit alongside.

What this means for landlord acquisition planning post-abolition

The post-abolition SDLT landscape is harder for most landlord and portfolio-buyer transactions than the pre-abolition landscape was. For four-or-five-dwelling acquisitions in particular, MDR was the relief that materially shaped the deal economics; without it, the residential-plus-surcharge baseline is the realistic position and the acquisition price has to absorb that SDLT cost. The structural responses are jurisdictional (does the deal fit s.116(7), Schedule 15 SLP, or section 45?), transactional (can the deal shape change to bring it into one of the surviving routes?), and modelling-led (is the post-abolition SDLT cost commercially viable at the agreed price, or does the price need renegotiation?).

For pre-abolition contracts that are still working through to completion, the transitional analysis is the load-bearing question. Section 7(4)(a) protects the substantially-performed-pre-1-June-2024 cohort; section 7(4)(b) protects the pre-6-March-2024 contract cohort subject to the section 7(5) exclusions. Any post-Budget paperwork (variations, assignments, options exercised, sub-sales) is a potential anti-forestalling trigger and merits specialist review before completion. The case for getting the analysis right pre-completion is straightforward: a post-completion HMRC challenge on an incorrectly-claimed MDR will recover the full underpaid SDLT plus interest plus a potentially material Schedule 24 penalty layer.
