UK SDLT Commercial Property: 2026/27

UK SDLT Commercial Property 2026/27: Non-Residential Deep-Dive

Q: What are commercial / non-residential SDLT bands 2026/27?

Three-band stepped structure (Section 55 + Schedule 5 Finance Act 2003): 0% on consideration £0 to £150,000; 2% on £150,000 to £250,000; 5% on consideration above £250,000. Slice / stepped calculation (NOT slab - changed from slab method in March 2016 Budget): each band applies only to the portion of consideration within that band. Worked example - £500k commercial purchase : 0% × £150,000 = £0; 2% × £100,000 = £2000; 5% × £250,000 = £12500; total SDLT = £14500. Key difference from residential : NO additional-dwellings 5% surcharge (that applies only to residential). NO first-time-buyer relief. NO 17% non-resident surcharge (residential only). Rates apply uniformly regardless of buyer type. VAT consideration : SDLT calculated on VAT-INCLUSIVE consideration where VAT is payable (e.g., opted-to-tax commercial property + option to tax made by seller).

Q: How is SDLT calculated on commercial leases?

Two separate SDLT calculations for leasehold transactions. (1) Premium SDLT : any upfront premium / capital sum paid taxed at standard non-residential rates (0%/2%/5% slab above). (2) Rent NPV SDLT : future rent obligations discounted to Net Present Value at 3.5% (HMRC standard discount rate). NPV taxed at lease-specific bands. Lease NPV bands : 0% on NPV up to £150,000; 1% on NPV £150,000 to £5,000,000; 2% on NPV above £5,000,000. NPV formula : sum from year 1 to year n of (rent_year ÷ 1.035^year). For uniform rent, simpler formula = rent × ((1 - 1.035^(-n)) ÷ 0.035). Worked example - 10-year office lease at £40k annual rent : NPV ≈ £40,000 × ((1 - 1.035^(-10)) ÷ 0.035) = £40,000 × 8.317 = £332,664. Below £150k threshold = £0 lease SDLT due. Rent review impact : subsequent rent reviews don't trigger new SDLT unless they're upward "abnormal" reviews per Schedule 17A FA 2003. Lease assignment : typically NO new SDLT on assignment (Section 75 FA 2003) unless assignment is at a premium. Surrenders + extensions : each trigger new SDLT calculation if consideration paid.

Q: What is the 6+ dwelling rule?

Single transaction involving 6+ residential dwellings can elect to be taxed at NON-RESIDENTIAL rates (Section 116(7) FA 2003). Single most powerful relief for property portfolio purchases. Why elect : avoids the 5% additional-dwellings surcharge that would apply to each property individually. Worked example - £2.4m purchase of 6 residential flats : option (a) treat as 6 residential = £91k base SDLT per flat + 5% × £400k average × 6 = total ~£600k-£700k SDLT range. Option (b) elect non-residential under 6+ rule = 0% × £150k + 2% × £100k + 5% × £2.15m = £109,500 SDLT. Saving £490k+. Conditions : must be SINGLE transaction (one SPA, one completion, one set of documents); must involve 6+ residential dwellings; election made in SDLT return (form SDLT1). "Dwelling" definition : each self-contained habitable unit counts. Adjoining flats with separate entrances + facilities = separate dwellings. Bedsits sharing kitchen/bathroom = one dwelling. Practical use : institutional landlord acquisitions (build-to-rent, student housing, multi-let purchases), portfolio sales (e.g., HMO landlord retiring + selling 12 properties), corporate acquisitions of residential portfolios. Caution : election is irrevocable. Once made on SDLT return, cannot switch back if circumstances change.

Q: What was Multiple Dwellings Relief (MDR) and why was it abolished?

MDR (Multiple Dwellings Relief) : abolished from 1 June 2024 (Spring Budget 2024 announcement). For transactions completed BEFORE that date, MDR allowed buyers of multiple residential properties in a single (or linked) transaction to calculate SDLT on the AVERAGE price per property rather than the total - typically reducing SDLT significantly. Worked example pre-abolition : buy 3 flats for £1.5m total (£500k each). Without MDR: SDLT on £1.5m residential = £91,250 + 5% surcharge × £1.5m = £166,250. With MDR: SDLT on £500k average × 3 = £15k × 3 = £45k base + 5% surcharge × £1.5m = £120k. MDR saved £46k. Why abolished : HMRC concluded the relief was poorly targeted (intended for investors but used by ordinary buyers via artificial "granny annex" / "secondary unit" arguments) + significant revenue loss (~£800m/yr by 2023). Post-abolition alternatives : (a) 6+ dwelling rule (Section 116(7) FA 2003) - more restrictive (need 6+ units, single transaction) but still meaningful for institutional purchases; (b) corporate envelope structures (with ATED implications); (c) phased acquisitions across tax years (administratively difficult). Transitional rules : contracts EXCHANGED before 6 March 2024 + completed by 31 May 2024 retained MDR. Post-1 June 2024 completions don't qualify regardless of exchange date.

Q: How does SDLT interact with corporate structures?

Corporate buyer of residential property : triggers 17% flat rate SDLT (Section 55A FA 2003) on consideration above £500,000 - the "envelope penalty". Designed to discourage corporate ownership of high-value residential property. Exemptions : (a) property rental businesses where buying for genuine letting market; (b) property development businesses; (c) trade business properties; (d) employer dwellings for staff use; (e) farmhouses on working farms. Each exemption requires specific qualifying conditions + ongoing compliance. ATED (Annual Tax on Enveloped Dwellings) : separate annual charge on corporate-held residential property valued > £500,000. ATED bands 2026/27: £500k-£1m = £4,650/yr; £1m-£2m = £9,500; £2m-£5m = £32,100; £5m-£10m = £74,950; £10m-£20m = £150,400; £20m+ = £301,150. Same exemptions as 17% SDLT generally apply to ATED. Group reliefs : Section 42 FA 2003 - SDLT-free transfers between 75%+ commonly-owned group companies. Strict 3-year clawback if companies degroup. SDLT 15% surcharge for non-resident corporates on residential: applies to non-UK-resident company buyers. Corporate purchase of commercial : no special surcharge - standard non-residential rates apply (0%/2%/5%).

Q: What are linked transactions and how do they affect SDLT?

Linked transactions (Section 108 FA 2003): two or more transactions between same parties (or connected parties) counted as ONE for SDLT band purposes. Designed to prevent artificial splitting to stay below SDLT bands. How "linked" tested : HMRC looks at: (a) common buyer/seller (direct or via connected entities); (b) overall scheme / arrangement linking transactions; (c) sequence + commercial dependence (one purchase conditional on another); (d) timing proximity (typically 6 months but no statutory deadline). Worked example : company sells two adjoining commercial units to two related companies (sister subsidiaries) for £200k each. Linked - SDLT calculated on £400k total = 0% × £150k + 2% × £100k + 5% × £150k = £9,500. NOT £200k × 2 = £100k each band = £1,000 + £1,000 = £2,000. Linked treatment costs £7,500 more. Anti-fragmentation rule : cannot split contracts within a single SPA to game band thresholds - HMRC will treat as single transaction regardless. Penalty : deliberate / careless under-disclosure of linked status triggers Schedule 24 FA 2007 penalties (0-100% of unpaid SDLT). Practical advice : disclose linked transactions transparently in SDLT1 return; obtain pre-transaction HMRC clearance for complex structures via Non-Statutory Clearance procedure.

Q: What reliefs and exemptions are available?

Commercial SDLT reliefs (selected key ones): Group relief Section 42 FA 2003 - SDLT-free transfers between 75%+ commonly-owned group companies, subject to 3-year clawback if degrouping. Reconstruction relief Section 42(2) FA 2003 - schemes of arrangement, asset transfers. Acquisition relief Schedule 7 FA 2003 - business asset transfers between businesses under common control. Charities relief Section 68 + Schedule 8 FA 2003 - SDLT exemption for transfers to UK-registered charities. Sale and leaseback relief Section 57A FA 2003 - simultaneous sale + lease of same property exempt under specific conditions. Public bodies relief - Crown, local authorities, NHS, certain quangos. Compulsory purchase relief - properties acquired by public authorities under CPO. Right-to-buy relief Schedule 9 FA 2003 - council/HA tenants exercising statutory RTB. Crofting community relief Section 71 FA 2003 - Scottish crofting community land transfers (Scotland LBTT but similar rule applies). Subsidiary dwellings (granny annex) - removed for SDLT purposes when MDR abolished but residual considerations apply. Each relief requires : claim made in SDLT return + supporting documentation + ongoing compliance for clawback periods.

Q: When and how do I pay SDLT on commercial purchases?

14-day deadline (changed from 30 days October 2019 - Section 76 FA 2003 as amended). SDLT1 return + payment due within 14 days of "effective date" (typically completion date for purchases, substantial performance date for leases). Filing : online via HMRC SDLT portal or accountant's professional software. Manual SDLT1 (paper) still available but online preferred. Payment methods : BACS (most common - 3 working days clearance), CHAPS (same-day for high-value), Faster Payments. Cash / cheque not accepted at HMRC level. Late filing penalties : £100 immediate fine; £200 after 3 months; tax-geared penalty 5%-100% after 12 months (Schedule 10 FA 2007). Late payment interest : HMRC official rate (currently ~7%) from day 1 of overdue period. Errors / amendments : 12-month amendment window from filing date. After 12 months, errors require HMRC discovery / voluntary disclosure. Conveyancing solicitor's role : typically handles SDLT filing + payment on completion as part of legal fees. Buyer remains LEGALLY LIABLE - solicitor's failure doesn't shift liability. Buyer should verify SDLT1 was filed + payment cleared within 14 days. HMRC certificate : SDLT5 confirmation issued post-payment - required for HM Land Registry to register title transfer.

Q: How does the option to tax (VAT) affect SDLT on commercial?

Option to Tax (OTT) : VAT election made by COMMERCIAL property owner to charge VAT on sales / rents that would otherwise be exempt. Made via VAT 1614A notification to HMRC. Generally irrevocable for 20 years. SDLT impact : SDLT is calculated on the VAT-INCLUSIVE price. So a £1m commercial property where seller has opted to tax = £1.2m consideration for SDLT = £64,500 SDLT (vs £39,500 if no VAT). Why VAT matters : VAT-registered buyer can typically RECOVER the £200k input VAT - but cannot recover the £25k extra SDLT. So OTT increases SDLT cost permanently even where VAT is recoverable. Strategies to minimise : (a) Transfer of Going Concern (TOGC) - if seller is transferring an ongoing business (e.g., let property as investment business) the transfer can be VAT-exempt + OTT not applied, reducing SDLT base; (b) De-option (Section 47 + Schedule 10 VATA 1994) - if seller hasn't used the option in last 20 years AND no VAT recovered in last 6, can revoke OTT before sale; (c) Property in mixed-status group - careful structuring of which group entity holds property. Most common error : not factoring OTT into SDLT calculation early in transaction planning. Always confirm OTT status during due diligence + factor into deal economics.

Scenario	Consideration / rent	SDLT	Breakdown
Small office freehold purchase High street office purchase. Below £250k threshold = only 2% slice band applies.	£200,000	£1,000	0% on £150,000 + 2% on £50,000
Industrial unit freehold Mid-size warehouse / industrial unit. Crosses both 2% and 5% bands.	£600,000	£19,500	0% on £150,000 + 2% on £100,000 + 5% on £350,000

Office lease 10-yr, £40k rent NPV calculation discounts future rent at 3.5%. Small premium/rent leases typically below NPV threshold.	/ £40,000/yr × 10y	£1,827	NPV £332,664, lease SDLT 0% to £150,000 + 1% above
Office lease 20-yr, £100k rent + £200k premium Premium SDLT (standard non-resi rates) + NPV SDLT separately. Two SDLT calculations combined.	£200,000 / £100,000/yr × 20y	£13,712	Premium SDLT £1000 + Lease NPV (£1,421,240) SDLT £12712
Mixed-use shop with flat above Has ANY non-residential element = treated as ALL non-residential for SDLT (favourable for high-value mixed-use vs full residential rates).	£500,000	£14,500	0% on £150,000 + 2% on £100,000 + 5% on £250,000
6+ dwelling portfolio purchase Single transaction of 6+ residential properties can ELECT non-residential rates (often substantial saving vs additional-dwellings 5% surcharge per property).	£2,400,000	£109,500	0% on £150,000 + 2% on £100,000 + 5% on £2,150,000

Lease NPV calculation method

For leasehold transactions, SDLT splits into TWO separate calculations: premium SDLT (any upfront capital sum at standard non-residential rates) + lease NPV SDLT (future rent obligations discounted to Net Present Value at 3.5%).

NPV range	Rate	Notes
£0 - £150,000	0%	Most short-term office / retail leases fall here
£150,000 - £5,000,000	1%	High-rent long-term commercial leases
Above £5,000,000	2%	Major prime office / shopping centre leases

NPV formula for uniform annual rent: NPV = rent × ((1 - 1.035^(-n)) / 0.035) where n = lease term in years. For variable rent (e.g., rent reviews built in), discount each year's projected rent individually.

Mixed-use vs residential - the rate arbitrage

Properties with ANY genuine non-residential element are treated as ENTIRELY non-residential for SDLT (Section 55 + Schedule 5 FA 2003). For high-value properties this is a significant tax saving versus pure residential rates - particularly with the 5% additional-dwellings surcharge eliminated.

£1.5m shop + flat above (mixed-use)

Non-residential SDLT: 0% × £150k + 2% × £100k + 5% × £1.25m = £64,500

£1.5m pure residential + ADS

Residential SDLT + 5% surcharge = £166,250

Mixed-use saves £100k+

Caution: HMRC aggressively challenges artificial mixed-use claims. Hyman v HMRC 2019 + Goodfellow v HMRC 2021 established high evidential bar. Genuine examples (shop + flat above, pub with manager's accommodation, farm + farmhouse) work; artificial claims (paddock for owner's horse, home office) get rejected with penalties.

Frequently asked questions

What are commercial / non-residential SDLT bands 2026/27?

Three-band stepped structure (Section 55 + Schedule 5 Finance Act 2003): 0% on consideration £0 to £150,000; 2% on £150,000 to £250,000; 5% on consideration above £250,000. Slice / stepped calculation (NOT slab - changed from slab method in March 2016 Budget): each band applies only to the portion of consideration within that band. Worked example - £500k commercial purchase: 0% × £150,000 = £0; 2% × £100,000 = £2000; 5% × £250,000 = £12500; total SDLT = £14500. Key difference from residential: NO additional-dwellings 5% surcharge (that applies only to residential). NO first-time-buyer relief. NO 17% non-resident surcharge (residential only). Rates apply uniformly regardless of buyer type. VAT consideration: SDLT calculated on VAT-INCLUSIVE consideration where VAT is payable (e.g., opted-to-tax commercial property + option to tax made by seller).

How is SDLT calculated on commercial leases?

Two separate SDLT calculations for leasehold transactions. (1) Premium SDLT: any upfront premium / capital sum paid taxed at standard non-residential rates (0%/2%/5% slab above). (2) Rent NPV SDLT: future rent obligations discounted to Net Present Value at 3.5% (HMRC standard discount rate). NPV taxed at lease-specific bands. Lease NPV bands: 0% on NPV up to £150,000; 1% on NPV £150,000 to £5,000,000; 2% on NPV above £5,000,000. NPV formula: sum from year 1 to year n of (rent_year ÷ 1.035^year). For uniform rent, simpler formula = rent × ((1 - 1.035^(-n)) ÷ 0.035). Worked example - 10-year office lease at £40k annual rent: NPV ≈ £40,000 × ((1 - 1.035^(-10)) ÷ 0.035) = £40,000 × 8.317 = £332,664. Below £150k threshold = £0 lease SDLT due. Rent review impact: subsequent rent reviews don't trigger new SDLT unless they're upward "abnormal" reviews per Schedule 17A FA 2003. Lease assignment: typically NO new SDLT on assignment (Section 75 FA 2003) unless assignment is at a premium. Surrenders + extensions: each trigger new SDLT calculation if consideration paid.

What is the mixed-use rule?

Property with ANY non-residential element is treated as ENTIRELY non-residential for SDLT - so non-residential rates apply to the whole purchase price (not split between residential + non-residential proportions). Section 55 + Schedule 5 FA 2003. Practical impact: significant tax saving for high-value mixed-use properties. A £1.5m shop with flat above pays £64,500 commercial SDLT (£0 + £2k + £62.5k); same £1.5m as pure residential = £91,250 standard + £75k additional-dwellings surcharge if buyer has another property = £166,250 total. Mixed-use saves £100k+. HMRC challenge: aggressive enforcement against artificial mixed-use claims. Common challenges: gardens / outbuildings claimed as agricultural ("non-residential") - HMRC requires GENUINE non-residential use, not theoretical. Hyman v HMRC 2019 + Goodfellow v HMRC 2021 cases established high evidential bar. Genuine examples: shop + residential flat above (clear), pub with manager's accommodation (clear), residential property with substantial commercial yard / car-park used by separate business (defensible), farmhouse + working agricultural land (defensible with proper evidence). Artificial / risky: residential property with paddock used purely for owner's horse (HMRC likely to challenge), home with home-office (clearly still residential). Documentation: maintain evidence of non-residential use (lease agreements, business income receipts, planning permissions) for at least 6 years post-purchase.

What is the 6+ dwelling rule?

Single transaction involving 6+ residential dwellings can elect to be taxed at NON-RESIDENTIAL rates (Section 116(7) FA 2003). Single most powerful relief for property portfolio purchases. Why elect: avoids the 5% additional-dwellings surcharge that would apply to each property individually. Worked example - £2.4m purchase of 6 residential flats: option (a) treat as 6 residential = £91k base SDLT per flat + 5% × £400k average × 6 = total ~£600k-£700k SDLT range. Option (b) elect non-residential under 6+ rule = 0% × £150k + 2% × £100k + 5% × £2.15m = £109,500 SDLT. Saving £490k+. Conditions: must be SINGLE transaction (one SPA, one completion, one set of documents); must involve 6+ residential dwellings; election made in SDLT return (form SDLT1). "Dwelling" definition: each self-contained habitable unit counts. Adjoining flats with separate entrances + facilities = separate dwellings. Bedsits sharing kitchen/bathroom = one dwelling. Practical use: institutional landlord acquisitions (build-to-rent, student housing, multi-let purchases), portfolio sales (e.g., HMO landlord retiring + selling 12 properties), corporate acquisitions of residential portfolios. Caution: election is irrevocable. Once made on SDLT return, cannot switch back if circumstances change.

What was Multiple Dwellings Relief (MDR) and why was it abolished?

MDR (Multiple Dwellings Relief): abolished from 1 June 2024 (Spring Budget 2024 announcement). For transactions completed BEFORE that date, MDR allowed buyers of multiple residential properties in a single (or linked) transaction to calculate SDLT on the AVERAGE price per property rather than the total - typically reducing SDLT significantly. Worked example pre-abolition: buy 3 flats for £1.5m total (£500k each). Without MDR: SDLT on £1.5m residential = £91,250 + 5% surcharge × £1.5m = £166,250. With MDR: SDLT on £500k average × 3 = £15k × 3 = £45k base + 5% surcharge × £1.5m = £120k. MDR saved £46k. Why abolished: HMRC concluded the relief was poorly targeted (intended for investors but used by ordinary buyers via artificial "granny annex" / "secondary unit" arguments) + significant revenue loss (~£800m/yr by 2023). Post-abolition alternatives: (a) 6+ dwelling rule (Section 116(7) FA 2003) - more restrictive (need 6+ units, single transaction) but still meaningful for institutional purchases; (b) corporate envelope structures (with ATED implications); (c) phased acquisitions across tax years (administratively difficult). Transitional rules: contracts EXCHANGED before 6 March 2024 + completed by 31 May 2024 retained MDR. Post-1 June 2024 completions don't qualify regardless of exchange date.

How does SDLT interact with corporate structures?

Corporate buyer of residential property: triggers 17% flat rate SDLT (Section 55A FA 2003) on consideration above £500,000 - the "envelope penalty". Designed to discourage corporate ownership of high-value residential property. Exemptions: (a) property rental businesses where buying for genuine letting market; (b) property development businesses; (c) trade business properties; (d) employer dwellings for staff use; (e) farmhouses on working farms. Each exemption requires specific qualifying conditions + ongoing compliance. ATED (Annual Tax on Enveloped Dwellings): separate annual charge on corporate-held residential property valued > £500,000. ATED bands 2026/27: £500k-£1m = £4,650/yr; £1m-£2m = £9,500; £2m-£5m = £32,100; £5m-£10m = £74,950; £10m-£20m = £150,400; £20m+ = £301,150. Same exemptions as 17% SDLT generally apply to ATED. Group reliefs: Section 42 FA 2003 - SDLT-free transfers between 75%+ commonly-owned group companies. Strict 3-year clawback if companies degroup. SDLT 15% surcharge for non-resident corporates on residential: applies to non-UK-resident company buyers. Corporate purchase of commercial: no special surcharge - standard non-residential rates apply (0%/2%/5%).

What are linked transactions and how do they affect SDLT?

Linked transactions (Section 108 FA 2003): two or more transactions between same parties (or connected parties) counted as ONE for SDLT band purposes. Designed to prevent artificial splitting to stay below SDLT bands. How "linked" tested: HMRC looks at: (a) common buyer/seller (direct or via connected entities); (b) overall scheme / arrangement linking transactions; (c) sequence + commercial dependence (one purchase conditional on another); (d) timing proximity (typically 6 months but no statutory deadline). Worked example: company sells two adjoining commercial units to two related companies (sister subsidiaries) for £200k each. Linked - SDLT calculated on £400k total = 0% × £150k + 2% × £100k + 5% × £150k = £9,500. NOT £200k × 2 = £100k each band = £1,000 + £1,000 = £2,000. Linked treatment costs £7,500 more. Anti-fragmentation rule: cannot split contracts within a single SPA to game band thresholds - HMRC will treat as single transaction regardless. Penalty: deliberate / careless under-disclosure of linked status triggers Schedule 24 FA 2007 penalties (0-100% of unpaid SDLT). Practical advice: disclose linked transactions transparently in SDLT1 return; obtain pre-transaction HMRC clearance for complex structures via Non-Statutory Clearance procedure.

What reliefs and exemptions are available?

Commercial SDLT reliefs (selected key ones): Group relief Section 42 FA 2003 - SDLT-free transfers between 75%+ commonly-owned group companies, subject to 3-year clawback if degrouping. Reconstruction relief Section 42(2) FA 2003 - schemes of arrangement, asset transfers. Acquisition relief Schedule 7 FA 2003 - business asset transfers between businesses under common control. Charities relief Section 68 + Schedule 8 FA 2003 - SDLT exemption for transfers to UK-registered charities. Sale and leaseback relief Section 57A FA 2003 - simultaneous sale + lease of same property exempt under specific conditions. Public bodies relief - Crown, local authorities, NHS, certain quangos. Compulsory purchase relief - properties acquired by public authorities under CPO. Right-to-buy relief Schedule 9 FA 2003 - council/HA tenants exercising statutory RTB. Crofting community relief Section 71 FA 2003 - Scottish crofting community land transfers (Scotland LBTT but similar rule applies). Subsidiary dwellings (granny annex) - removed for SDLT purposes when MDR abolished but residual considerations apply. Each relief requires: claim made in SDLT return + supporting documentation + ongoing compliance for clawback periods.

When and how do I pay SDLT on commercial purchases?

14-day deadline (changed from 30 days October 2019 - Section 76 FA 2003 as amended). SDLT1 return + payment due within 14 days of "effective date" (typically completion date for purchases, substantial performance date for leases). Filing: online via HMRC SDLT portal or accountant's professional software. Manual SDLT1 (paper) still available but online preferred. Payment methods: BACS (most common - 3 working days clearance), CHAPS (same-day for high-value), Faster Payments. Cash / cheque not accepted at HMRC level. Late filing penalties: £100 immediate fine; £200 after 3 months; tax-geared penalty 5%-100% after 12 months (Schedule 10 FA 2007). Late payment interest: HMRC official rate (currently ~7%) from day 1 of overdue period. Errors / amendments: 12-month amendment window from filing date. After 12 months, errors require HMRC discovery / voluntary disclosure. Conveyancing solicitor's role: typically handles SDLT filing + payment on completion as part of legal fees. Buyer remains LEGALLY LIABLE - solicitor's failure doesn't shift liability. Buyer should verify SDLT1 was filed + payment cleared within 14 days. HMRC certificate: SDLT5 confirmation issued post-payment - required for HM Land Registry to register title transfer.

How does the option to tax (VAT) affect SDLT on commercial?

Option to Tax (OTT): VAT election made by COMMERCIAL property owner to charge VAT on sales / rents that would otherwise be exempt. Made via VAT 1614A notification to HMRC. Generally irrevocable for 20 years. SDLT impact: SDLT is calculated on the VAT-INCLUSIVE price. So a £1m commercial property where seller has opted to tax = £1.2m consideration for SDLT = £64,500 SDLT (vs £39,500 if no VAT). Why VAT matters: VAT-registered buyer can typically RECOVER the £200k input VAT - but cannot recover the £25k extra SDLT. So OTT increases SDLT cost permanently even where VAT is recoverable. Strategies to minimise: (a) Transfer of Going Concern (TOGC) - if seller is transferring an ongoing business (e.g., let property as investment business) the transfer can be VAT-exempt + OTT not applied, reducing SDLT base; (b) De-option (Section 47 + Schedule 10 VATA 1994) - if seller hasn't used the option in last 20 years AND no VAT recovered in last 6, can revoke OTT before sale; (c) Property in mixed-status group - careful structuring of which group entity holds property. Most common error: not factoring OTT into SDLT calculation early in transaction planning. Always confirm OTT status during due diligence + factor into deal economics.

What is ATED and how does it affect commercial / residential property?

ATED (Annual Tax on Enveloped Dwellings): annual charge on RESIDENTIAL property held by non-natural persons (companies, partnerships with corporate members, collective investment vehicles) valued above £500,000. Not applicable to commercial property. Statutory basis: Sections 94-188 Finance Act 2013. Bands 2026/27: £500k-£1m = £4,650; £1m-£2m = £9,500; £2m-£5m = £32,100; £5m-£10m = £74,950; £10m-£20m = £150,400; £20m+ = £301,150. Annual filing: ATED return required by 30 April of each tax year, even when claiming relief. Reliefs available: rental property business (most common), property development, property trading, dwellings for employees, dwellings open to public, financial institutions, farmhouses. Each requires specific qualifying conditions. Practical implications for portfolio holders: corporate-held residential with value > £500k = ATED return + payment annually + initial 17% flat SDLT on acquisition (if not exempt) + ongoing compliance burden. For commercial property, none of these apply - commercial held in corporate envelope is the "default" structure with no special enveloping penalties. 2026 reform consultation: HMRC consulting on ATED simplification (potential merger with non-resident SDLT surcharge). Implementation TBA.

How does SDLT differ across UK jurisdictions?

Three separate land transaction taxes: England + Northern Ireland: SDLT - bands above (0%/2%/5% commercial). Scotland: LBTT (Land and Buildings Transaction Tax) - similar slice structure but DIFFERENT bands. LBTT commercial bands 2026/27: 0% to £150k, 1% £150k-£250k, 5% above £250k. Plus 6% LBTT Additional Dwelling Supplement on residential 2nd properties (vs 5% SDLT). Statutory basis: Land and Buildings Transaction Tax (Scotland) Act 2013. Wales: LTT (Land Transaction Tax) - similar structure to SDLT. LTT commercial bands 2026/27: 0% to £225k, 1% £225k-£250k, 5% £250k-£1m, 6% above £1m. Statutory basis: Land Transaction Tax and Anti-avoidance of Devolved Taxes (Wales) Act 2017. Common features all three: stepped/slice calculation, separate lease NPV calc, mixed-use rules, group reliefs broadly equivalent. Cross-jurisdictional purchases: location of property determines applicable tax regardless of buyer's location. Buyer based in London buying commercial unit in Edinburgh pays LBTT (not SDLT). HMRC vs devolved authorities: SDLT collected by HMRC; LBTT by Revenue Scotland; LTT by Welsh Revenue Authority. Each has own filing portal + deadlines (LBTT/LTT 30 days, SDLT 14 days). Practical note: investment portfolios spanning multiple jurisdictions need separate compliance for each.
