The Tour Operators' Margin Scheme has been a structural pillar of how serviced-accommodation operators in the UK manage VAT for at least a decade. By taxing the operator's margin rather than the full sale price, TOMS could turn a £1.2m gross-revenue business into a £300,000 VATable turnover for registration and output-tax purposes. For operators with thin margins, the difference between paying 20% VAT on the margin and 20% VAT on the gross was the difference between a viable business and a loss-making one.
In March 2024, the Upper Tribunal in Sonder Europe Ltd v HMRC reversed the First-tier Tribunal and held that the most common operating model (taking long leases from residential landlords, furnishing and branding the units, and on-selling short-stay nights to travellers) does not qualify for TOMS. The decision did not abolish TOMS for serviced accommodation, but it narrowed it sharply: only operators that genuinely buy in and on-sell short-stay room nights without material alteration remain within the scheme.
This page covers what TOMS is, the operating-model test the Upper Tribunal applied, the financial impact of falling outside, and the routes that still work post-Sonder.
What TOMS Is and How It Works
TOMS sits in section 53 of the Value Added Tax Act 1994 and is detailed in HMRC's VAT Notice 709/5. It is a special scheme for businesses that buy in travel-type services from third parties (transport, accommodation, sightseeing, ancillary services) and resell them to travellers without material alteration.
Under TOMS:
- The operator's relevant turnover is the margin (sale price minus the cost of bought-in services), not the gross sales.
- Output VAT is calculated on the margin at the standard rate.
- Input VAT on the bought-in services is not recoverable (it is reflected in the margin calculation).
- The £90,000 VAT registration threshold is tested against the margin figure, not against gross sales.
The scheme was originally designed for tour operators (hence the name) but its scope extends to any business that meets the bought-in-and-resold-without-material-alteration test, including coach operators, conference organisers, and (historically) certain serviced-accommodation models.
The Conditions for TOMS Eligibility
The Sonder decision tightened the focus on three of the standard TOMS conditions:
- The supply must be of designated travel services: accommodation, transport, restaurant meals, or sightseeing/excursion services.
- The supply must be made for the benefit of travellers. Travellers includes business travellers and corporate clients booking for their staff.
- The supplies must be bought in from third parties, not self-provided. And the operator must not have materially altered or further processed them before resale.
The third condition is where Sonder fell over. The Upper Tribunal's analysis was that Sonder had not just on-sold a bought-in service; it had used the bought-in service as an input into a different supply.
The Sonder Europe Case in Detail
The Business Model
Sonder Europe operated a UK serviced-accommodation business in the period from 2017 to 2020. The business model:
- Sonder took long-term leases (typically 5 to 10 years) on flats from residential landlords.
- Sonder furnished, decorated, and branded each unit to a consistent Sonder standard.
- Sonder provided cleaning, linen changes, Wi-Fi, and reception/guest-service support.
- Sonder marketed the units on its own website and on third-party platforms.
- Travellers booked short-stay nights (typically two to fourteen nights) at nightly rates set by Sonder.
Sonder claimed TOMS for the supplies to travellers on the basis that the long lease from the landlord was a bought-in accommodation service that Sonder on-sold without material alteration.
The First-tier Tribunal Decision (2023)
The FTT agreed with Sonder. The Tribunal held that the long lease was a supply of accommodation, Sonder had bought it in, and the on-sale to travellers was the same accommodation service. The furnishings, cleaning, and branding were ancillary and did not change the essential nature of the supply.
The Upper Tribunal Reversal (March 2024)
HMRC appealed. The Upper Tribunal reversed the FTT and held in HMRC's favour on three grounds:
- A long-term residential lease and a short-stay furnished serviced accommodation night are not the same supply for VAT purposes. They have different durations, different exempt-vs-taxable status (the long lease is typically exempt from VAT; the short-stay supply is taxable), and different commercial substance.
- The operator's activities of furnishing, branding, cleaning, providing reception, and converting a long-term residential interest into a short-stay product constitute material alteration or further processing. They are not merely ancillary to an on-sale of the original supply.
- The supplier did not buy in something it then sold on. It bought in an input and used it to create something different.
The Upper Tribunal noted that an operator that buys short-stay room nights from a hotel and on-sells them to a corporate client without alteration would still qualify for TOMS. The narrowing was specific to the long-lease-into-short-let pattern.
The Financial Impact of Falling Outside TOMS
Consider a serviced-accommodation operator with the following profile:
- Gross short-stay revenue: £1.2m per year.
- Rent paid to landlords on long leases: £900,000 per year (typically exempt from VAT because the landlords have not opted to tax residential property).
- Operating costs (cleaning, utilities, marketing, staff): £200,000 per year.
- Operator's margin: £100,000.
Under TOMS, the relevant turnover for registration is the margin (£300,000 on the bought-in services calculation, computed in line with TOMS-specific rules). Output VAT is around £50,000 a year on the margin. Input VAT on operating costs is not separately recoverable; it is reflected in the margin.
Outside TOMS:
- Gross sales of £1.2m are within the £90,000 registration threshold trigger from day one.
- Output VAT on £1.2m × 20% = £240,000.
- Input VAT recovery: the landlord rent (£900,000) is exempt, so no input VAT to recover. The operating costs (£200,000) include some VAT-bearing supplies (cleaning, utilities, marketing) on which input VAT can be recovered, typically £20,000 to £30,000.
- Net VAT cost: roughly £210,000 a year.
The £160,000 a year swing (£210,000 standard minus £50,000 TOMS) is enough to make the difference between a sustainable operating margin and a loss-making business. Operators have responded in three principal ways: passing the VAT through in nightly rates (the easiest in strong-demand locations), renegotiating landlord rents downward (slow and lease-dependent), or restructuring to bring properties into the operator's ownership so the supply chain changes.
Operating Models That Still Qualify After Sonder
Buy-In and Resell of Short-Stay Room Nights
The historically clean TOMS case. An operator contracts with hotels, aparthotels, or short-stay operators for blocks of room nights at wholesale rates, and on-sells them to corporate clients or to consumers without altering the substantive nature of the accommodation. Cleaning, linen, and reception are provided by the underlying hotel; the operator's role is procurement and distribution. TOMS continues to apply on the operator's margin.
Inbound Tour Operator (Traditional TOMS Case)
An operator packaging UK accommodation with transport, sightseeing, and meals for overseas tour groups. Each component is bought in from third-party providers and on-sold to the tour group without material alteration. The package-pricing model fits TOMS naturally.
Corporate Short-Stay Aggregation
An operator that aggregates short-stay accommodation needs for corporate clients (typically multinationals relocating staff) by buying short-stay nights from a network of serviced-accommodation operators and on-selling them to the corporate. The operator does not own, lease, furnish, or operate the underlying accommodation; the supply on-sold is the same as the supply bought in. TOMS continues to apply.
Models That Now Fall Outside
Long-Lease-and-Short-Let (Sonder Pattern)
The Sonder model: taking long leases from landlords, furnishing and branding, and on-selling short-stay nights. After the Upper Tribunal decision, this falls outside TOMS. The operator makes a standard-rated supply at full sale price, registers and accounts for VAT on the gross.
Direct-Owned Serviced Accommodation
An operator that owns or holds long-leases on the underlying property and lets it directly to travellers makes its own supply of accommodation, not a bought-in-and-resold supply. TOMS has never applied to this model.
Management-Agreement Models (Variable)
Where the operator manages property for a landlord under a management agreement (commission-based, with the landlord remaining the principal supplier of accommodation), the VAT analysis depends on whether the operator is acting as agent or principal. Agent-based management agreements typically produce a commission supply by the operator, which is standard-rated but on the commission amount only.
What Operators Should Do Now
For an existing operator that has been applying TOMS, the post-Sonder response sequence is:
- Review the operating model against the Upper Tribunal's reasoning. The dispositive question is whether the supply on-sold is the same supply as the one bought in. A long lease into short-stay is the paradigmatic now-outside case.
- Identify the four-year window for HMRC enquiry on historical TOMS returns. Voluntary disclosure of the TOMS-no-longer-applies position carries lower inaccuracy penalties than waiting for an HMRC challenge.
- Model the standard-VAT position prospectively, including pricing options and the impact on landlord-rent negotiations.
- Consider structural alternatives: VAT grouping with the landlord SPV (where feasible), direct ownership, or genuinely buy-in-and-resell remodelling.
- Document the analysis: HMRC compliance activity on serviced-accommodation VAT has increased materially since the Upper Tribunal decision, and contemporaneous analysis is the principal defence on inaccuracy-penalty exposure.
For a new entrant designing a serviced-accommodation business in 2026, the VAT structuring choice is much more constrained than it was pre-Sonder. The long-lease-and-short-let model now carries a near-certain standard-VAT outcome, and the financial model has to absorb that from day one rather than relying on TOMS to keep the VAT burden manageable.
How VAT Sits Alongside the Wider Property-Tax Position
Serviced accommodation operators have a complex direct-tax position as well. The April 2025 abolition of the Furnished Holiday Letting regime removed historical income-tax and CGT advantages that some operators had relied on. The VAT position covered on this page sits alongside the income-tax position covered in income tax rates for landlords in 2026/27 and the corporation-tax position covered in corporation tax rates for property companies in 2026/27 for operators trading through a Ltd Co structure.
VAT is rarely the dominant tax cost for an owner-occupier landlord, but for serviced-accommodation operators it is structurally the largest tax line in the P&L. Getting it wrong after Sonder is materially more expensive than getting it right.
