The Tour Operators Margin Scheme, known as TOMS, sat at the heart of why the January 2026 private hire VAT change moved the numbers so far. It is a special VAT regime, designed for travel businesses that buy in travel services and resell them, under which VAT is charged on the operator's margin rather than on the gross fare. For a period, ride-hailing operators argued TOMS could apply to their supplies. The argument has effectively closed. This piece sits within [the 2026 Private Hire VAT changes hub](/insights/private-hire-vat-changes-january-2026/).
To see why the closure matters, the companion piece on [why London Uber fares now face 20% VAT](/blog/london-uber-fares-20-percent-vat-january-2026/) sets out the full-fare outcome that fills the gap TOMS used to occupy. For the structural contract question that drove the shift, read [principal versus agent contracts](/blog/principal-vs-agent-uber-london-rest-uk/).

What TOMS actually is
TOMS is a compulsory VAT scheme for businesses that buy in and resell certain travel services as a principal. Where it applies, the supplier accounts for VAT on the margin between what it charges the customer and what it pays its suppliers for the bought-in travel components, rather than on the gross sale price. The scheme exists to simplify VAT for genuinely cross-border tour-operator-style supplies where multiple bought-in services are bundled into a single package for the traveller.
The margin-only base is what makes TOMS commercially attractive when it does apply. A scheme that bites on a slice of margin instead of the gross sale value can dramatically reduce the absolute VAT cost, even at the same headline rate, because the taxable base is much smaller.
Why ride-hailing operators argued for TOMS
The commercial appeal is obvious. If a ride-hailing operator could fit its supplies into TOMS, VAT would apply to its margin (broadly, its commission slice) rather than to the gross passenger fare. On a typical fare, that would shrink the embedded VAT cost by a large multiple. With volumes in the millions of journeys a week, even a modest difference per fare compounds into a material number across a year.
The argument rested on the idea that the operator was buying in a transport service from the driver and reselling it to the passenger, in the way a tour operator buys in hotel rooms and resells them as part of a package. If the operator was acting as a principal reseller of a bought-in travel service, TOMS, in principle, could apply.
Why HMRC and the courts disagreed
HMRC's position, upheld through litigation, is that the typical ride-hailing structure does not meet the conditions for TOMS in the way operators had hoped. The detailed reasoning sits in the cases and HMRC notices, but the substance is that TOMS was designed for genuine package-travel supplies and not for general transport services arranged through a platform.
Once TOMS was off the table, the default VAT rule applied: a standard-rated transport service is taxed at 20% on the value of the supply. In the principal model for London private hire, the value of the supply is the gross fare. That is the change that ate the margin-versus-gross-fare difference, and it is why the January 2026 outcome felt so much larger than a percentage-point tweak.
The litigation in short
A series of cases through the 2020s tested whether ride-hailing supplies fitted within TOMS. The detail varied case by case, but the consistent thread is that the courts did not accept the TOMS analysis for the typical operator structure. Drivers should treat the position as settled in practice from January 2026 onwards rather than expect a further reversal, while remembering that VAT case law can move and that operators may refine their structures over time.
How TOMS interacted with the principal-agent question
TOMS only mattered if the operator was a principal at all. If the operator was acting as an agent, introducing passenger to driver, the operator was not reselling a bought-in travel service in the TOMS sense; it was acting on behalf of the driver as supplier, and the driver was the principal supplier of the journey. In that case there was no TOMS argument to make, and VAT depended on the driver's own turnover and registration status.
The London licensing position pushed the major operators into the principal role for London bookings. That made the principal-versus-agent question concrete: operators were principals for London bookings, and the only remaining question was whether their principal supplies fitted within TOMS. With the answer to that question now effectively closed, the principal model produces a full-fare VAT charge.
Why the gap between margin and gross fare is so wide
A simple illustration shows why operators fought hard for TOMS. Take a £100 fare with a 25% operator commission. On a margin basis, the VAT base is around £25, so the VAT at 20% is around £5. On a gross basis, treating the £100 as VAT-inclusive, the embedded VAT is around £16.67. The same passenger journey, the same 20% rate, but the absolute VAT cost more than triples once the base shifts from margin to gross fare.
Multiply that gap across millions of journeys a week and the commercial weight of the TOMS question becomes obvious. The change is not really about the rate; it is about the size of the base.
What it means for drivers
A non-registered driver, in the London principal model, does not personally pay or charge any of this VAT. The cost sits at operator level. What changes for drivers is indirect, through operator pricing and commission decisions. Some of the impact is shared with passengers through fares; some may flow through to driver incentives and the structure of payouts. None of it lands as a flat deduction on driver earnings.
- TOMS is not a route a driver can use personally; it was an operator-level argument.
- With TOMS effectively closed, the operator's VAT cost in the principal model is on the gross fare, not the margin.
- The impact on driver take-home shows up through fare and commission changes, not as a personal VAT charge.
- Outside London, in agency structures, TOMS was never relevant because the driver, not the operator, is the supplier.
- Sub-threshold drivers are not pushed into VAT registration by the closure of the TOMS argument.
What it means for operators
For operators, the closure of the TOMS argument changes the VAT economics of being a principal supplier of a London journey. The full-fare VAT cost is real, and it is now part of how operators set fares and commissions. From a driver's vantage point, this is mostly someone else's problem, but it is worth knowing because operator decisions about commission structures, dynamic pricing, and incentives are downstream of this VAT change.
Could TOMS come back?
It is sensible to be cautious about that. VAT case law can move. Operators may refine the way they structure their supplies. HMRC may issue further guidance. But as of January 2026 the practical position is that the typical ride-hailing structure does not get the margin-only TOMS outcome, and the planning baseline is full-fare VAT in the principal model. Drivers and operators should plan on that basis rather than on the hope of a reversal.
A worked example for a London principal-model operator
Consider a London-only operator on £1bn of annual fares with a notional 25% commission. Under a margin-basis TOMS treatment, the VAT base would have been around £250m and the VAT at 20% around £50m. Under a full-fare basis, treating the fares as VAT-inclusive, the embedded VAT is around £167m. The gap, more than £100m a year, is the size of the commercial argument that was being run. It is also a rough measure of the pressure now sitting on fare and commission decisions.
Why this matters for fleet and high-earning drivers
For a fleet operator or a high-earning driver who is themselves VAT-registered, the closure of the TOMS argument matters in a different way. Their own supplies are still taxed on the same gross basis as anyone else, but the structure of the platforms they supply to is now clearer. They can plan their own commission expectations, fare calculations, and operator selection knowing that the underlying VAT model in the principal segment is a full-fare model. That clarity is useful even where it is not, in itself, good news.
How to think about TOMS in plain terms
- TOMS was a margin-only VAT regime that some operators argued fitted ride-hailing.
- HMRC and the courts have effectively closed that argument for the typical structure.
- The default rule then applies: 20% VAT on the gross value of a standard-rated transport supply.
- In the London principal model, the value is the gross fare.
- Outside London in agency structures, the operator was never the supplier of the journey, so TOMS was never the question.
