The £90,000 VAT registration threshold is the single number most likely to be misunderstood by private hire drivers. It applies to a driver's own taxable turnover, the value of supplies the driver makes as principal. It does not turn every driver into a VAT registrant the moment fares pass through an app. This piece is part of [the 2026 Private Hire VAT changes hub](/insights/private-hire-vat-changes-january-2026/), and it sets out precisely when an individual driver has to register.
The headline most drivers should hold onto is reassuring: most drivers fall well below £90,000 of their own taxable turnover, so for most it is the operator, not the driver, who is affected by VAT. The detail of who supplies the journey is in [principal versus agent contracts](/blog/principal-vs-agent-uber-london-rest-uk/), and the London-specific operator outcome is in [why London Uber fares now face 20% VAT](/blog/london-uber-fares-20-percent-vat-january-2026/).
What the £90,000 threshold actually measures
VAT registration is required when a business's taxable turnover exceeds the registration threshold, set at £90,000 from April 2024. Taxable turnover means the value of the supplies the business makes that are subject to VAT, including standard, reduced, and zero-rated supplies, but excluding VAT itself and excluding genuinely exempt supplies. For a private hire driver, the figure that matters is the value of the journeys the driver supplies as principal, not every pound that flows through an app.
That distinction is the crux. Where the operator is the principal supplier of the journey, the fare is the operator's taxable turnover, not the driver's. The driver's own taxable turnover, in that model, is the value of the services the driver provides, which is typically well below £90,000 for a single-vehicle driver.
The two registration tests
There are two ways the threshold can be breached, and a driver needs to watch both:
The rolling 12-month test is the one most drivers encounter. It is not a calendar-year or tax-year test; it looks at any consecutive 12 months. The forward-looking test is rarer for drivers but exists for sudden surges, for example a large one-off contract.
Why most drivers fall below it
A single-vehicle driver working full-time grosses a meaningful sum, but the £90,000 line is high, and crucially, in a principal-operator model the fares are not the driver's supply at all. Even where a driver is the supplier under an agency structure, a typical full-time driver's gross fares often sit below £90,000, and after the structural reality is applied many drivers are comfortably under. The threshold tends to catch a minority: high-earning, high-mileage drivers, multi-vehicle operators, or those running fleets, rather than the typical solo driver.
- Most single-vehicle drivers do not reach £90,000 of their own taxable turnover.
- In a principal-operator model the fares are the operator's turnover, not the driver's.
- The threshold most often bites on multi-vehicle operators and fleets, not solo drivers.
- A driver near the line should plan ahead rather than wait to be caught by the rolling test.
Who is usually affected: the operator, not the driver
Because operators handle very large volumes of fares, they are far above any threshold and account for VAT as a matter of course in the principal model. The driver, supplying their own services below £90,000, is usually outside the registration requirement. This is the opposite of the common fear that the 2026 changes force every driver to register. For most drivers the VAT change is felt, if at all, through operator pricing and commission decisions rather than a personal registration obligation.
When an individual driver does have to register
There are real situations where an individual driver crosses the line on their own taxable turnover:
Where one of these applies, the driver must register, charge VAT on their taxable supplies, and file VAT returns under Making Tax Digital for VAT. At that point, schemes such as the Flat Rate Scheme become relevant, because they can simplify accounting and sometimes improve the cash position for a driver with relatively low VAT-bearing costs.
A note on the Flat Rate Scheme
The Flat Rate Scheme lets a small business pay VAT as a fixed percentage of its VAT-inclusive turnover, rather than calculating output tax less input tax in detail. It can suit a VAT-registered driver with modest VAT-bearing costs, but the limited cost trader rules can apply a higher flat rate where input costs are low, which often describes a driver. The scheme is worth modelling with an accountant rather than assuming it helps; for some drivers standard VAT accounting is better.
How to monitor your own position
A driver who might approach the threshold should track their own taxable turnover on a rolling 12-month basis, not just per tax year. Practically, keep a running total of the supplies you make as principal, refreshed monthly, and watch the trailing 12-month figure. If that figure climbs toward £80,000 and is still rising, it is time to plan, because crossing £90,000 brings a hard 30-day registration deadline.
- Keep a monthly running total of your own taxable supplies.
- Look at the trailing 12 months, not the calendar or tax year.
- Separate principal-operator fares (not your supply) from agency-structure fares (your supply).
- Treat £80,000 as your planning trigger, not £90,000.
- If you cross the line, register within the deadline to avoid late-registration penalties.
What happens if you register late
If a driver should have registered and did not, HMRC can require VAT to be accounted for from the date registration was due, even if the driver did not charge VAT to customers in the meantime, which can leave the driver paying VAT out of income already received. Late-registration penalties may also apply. This is why the rolling 12-month monitoring matters: the cost of missing the line is real, and it falls on the driver personally.
Voluntary registration: rarely the right call for a solo driver
A business below the threshold can register voluntarily. For a solo private hire driver this is rarely attractive, because the main prize of voluntary registration, reclaiming input VAT, is limited where the driver's costs are modest and the Flat Rate Scheme or limited cost trader rules constrain the benefit. Voluntary registration also brings ongoing VAT returns and Making Tax Digital obligations. There are narrow cases where it helps, for example a large imminent vehicle purchase, but it should be modelled carefully before acting.
Deregistration if your turnover falls
Registration is not necessarily permanent. A driver whose taxable turnover drops, for example after switching from an agency-structure operator to a principal-model one, or after scaling back from multi-vehicle to single-vehicle working, may be able to deregister. HMRC allows deregistration where taxable turnover in the next 12 months is expected to fall below the deregistration threshold, which is set below the registration threshold. Deregistration can remove the administrative burden of VAT returns, but it also has consequences, including a potential charge on assets on hand, so it should be planned rather than rushed.
The point for drivers is that VAT status can move in both directions with your working pattern. A change of operator, a change of structure, or a change in how many vehicles you run can each shift whether you are above or below the line, so it is worth reviewing your position whenever your circumstances change materially.
A note on income tax and the VAT threshold
It helps to keep two separate questions apart. The £90,000 figure is the VAT registration threshold and concerns whether you must charge and account for VAT. It is not the same as the income tax personal allowance, the thresholds for income tax bands, or the Making Tax Digital for income tax thresholds, which work on different numbers and different rules. A driver can be inside Making Tax Digital for income tax (which catches far more drivers, at much lower income levels) while remaining comfortably below the VAT registration threshold. Conflating the two is a common source of confusion.
- VAT registration threshold: £90,000 of your own taxable turnover.
- Making Tax Digital for income tax: a separate, much lower threshold catching most full-time drivers.
- Income tax bands and personal allowance: different figures again, applied to profit not turnover.
- Being inside one regime does not automatically mean being inside another.
Putting it together
The £90,000 threshold applies to a driver's own taxable turnover. In the London principal model the fares are the operator's supply, so the typical driver is not pushed into registration by the 2026 changes. Outside London, agency-structure drivers measure their own fares against the threshold, and a minority of high earners and multi-vehicle operators will cross it. The safe approach is to know which structure you are in, monitor your own rolling turnover, and take advice before you reach the line.
