VAT Registration Requirements: Bookkeeping Checklist When the App Operator Is the Principal

VAT registration requirements for a private hire driver turn on one question: who sells the journey to the passenger? If your app operator acts as principal, it supplies the passenger and you supply driving services to the operator. If it acts as agent, you supply the passenger and every fare counts towards your own £90,000 limit.

Most drivers we speak to add up the wrong number. Some total the passenger fares on a principal operator's statement and worry about registering too early. Others total the net payouts from an agent firm and register months late. This guide for the 2026/27 tax year gives you a monthly checklist that our bookkeeping service for drivers uses to put each receipt in the right column.

Key takeaways

• The £90,000 VAT threshold applies to your own taxable turnover over any rolling 12 months, not to fares a passenger pays an operator.
• When an operator acts as principal, you count what it pays you for your services, adding back any charges it deducts from you.
• When an operator acts as agent, you count the full fares your passengers pay, before the operator's commission.
• London operators must act as principal. Outside London, operators can choose, following the Supreme Court's 2025 ruling.
• A change announced on 29 October 2026 would treat larger agent operators as the supplier from 2 January 2028, with the size threshold still to be consulted on.

What are VAT registration requirements for a private hire driver?

VAT registration requirements are the rules that say when you must register with HMRC for Value Added Tax (VAT). As a self-employed private hire driver, you must register once your own taxable turnover passes £90,000 in any rolling 12-month period, or if you expect to pass it in the next 30 days alone.

According to GOV.UK's guidance on registering for VAT, you must register within 30 days of the end of the month in which you went over £90,000. Taxable turnover is everything you sell that is not VAT exempt or outside the scope of VAT. The key word for drivers is "you": the test looks at your sales, not someone else's.

We cover the threshold mechanics, voluntary registration and the Flat Rate Scheme in our guide to VAT for ride-hailing drivers. This article deals with the step before all of that: deciding which money is actually your turnover in the first place.

Is there VAT on private hire fares in the UK?

Yes, but only when the business that legally sells the journey is VAT-registered. The standard 20% rate applies to private hire fares charged by registered businesses. If an unregistered driver below £90,000 is the supplier, the fare carries no VAT. If a registered operator is the principal supplier, VAT is due on the full fare.

The government set this out in its response to the consultation on VAT and private hire vehicles, last updated 26 November 2025. It confirmed that the 20% standard rate continues to apply to fares charged by VAT-registered businesses. It also rejected a reduced rate, a zero rate and a special margin scheme for private hire.

That is why two passengers can pay similar prices for similar trips and only one receipt shows VAT. The difference sits in the contract, not the car. For your bookkeeping, the question is never whether private hire is taxable in principle. It is who the supplier is.

Principal or agent: who supplies the journey?

HMRC's Notice 700/25 on taxis and private hire cars says a self-employed driver is normally in business on their own account. Your taxable supplies can include transport you provide directly to passengers. They can also include services you provide to another taxi or private hire business under a contract for services.

When the operator acts as principal

A principal operator contracts with the passenger to provide the journey. It sells the trip, collects the fare and, if registered, accounts for VAT on it. You supply your driving services to the operator, and the operator pays you for them. Your turnover is that payment, not the fare.

When the operator acts as agent

An agent operator takes bookings on your behalf and passes them to you for a fee. The passenger's contract for the journey is with you. Every fare is your supply, so the full fare counts towards your £90,000, and the operator's fee is a cost to you rather than a cut in turnover.

Notice 700/25 says agent status depends on the written or oral contract between the firm and its drivers, and on what happens in practice. A firm can act as agent for cash work and principal for account work. That split only holds where the contracts and day-to-day operations genuinely differ.

Why does London differ from the rest of England?

London operators must act as principal because of how the courts have read the London licensing Act. Outside London, the Supreme Court held in 2025 that the 1976 licensing Act does not force operators to contract as principal. So two operators in different cities can treat the same kind of driving work very differently for VAT.

In R (United Trade Action Group Ltd) v Transport for London, the Divisional Court declared in December 2021 that a London operator accepting a booking must contract with the passenger as principal to provide the journey. Operators licensed by Transport for London (TfL) work on that basis.

Outside London the route took longer. In 2023 the High Court, in a claim against Sefton Council and others, declared that a similar rule applied under the Local Government (Miscellaneous Provisions) Act 1976. The Court of Appeal discharged that declaration in July 2024. The Supreme Court then dismissed the further appeal in its judgment of 29 July 2025, cited as 2025 UKSC 31.

The Supreme Court found nothing in the 1976 Act that forces an operator to accept a booking only as principal. The practical result is a two-model market. Some operators outside London contract as principal anyway, while many local firms still act as agents. You cannot work out the model from the city, the app or the colour of the licence plate.

Scotland and Northern Ireland have their own licensing laws, and the 1976 Act does not cover every English area. If you drive outside England and Wales, check the position with your licensing authority and your operator's terms.

How do I tell which model my operator uses?

Read your driver agreement and your weekly statements together. A principal operator's terms typically say it provides transport to passengers and pays you for your services. An agent operator's terms typically say it arranges bookings for you and charges you a fee. If the wording is unclear, ask the operator in writing and keep the reply.

• Who the passenger receipt names as the business supplying the journey.
• Whether the operator's VAT number appears against the fare on the passenger receipt.
• Whether your statement describes deductions as "fees charged to you" or shows an "amount paid for your services".
• Whether the operator sets the fare and carries the risk of non-payment, or simply collects fares on your behalf.
• Any notice from the operator about a change of model, with the date it takes effect.

Keep a dated copy of the terms in force each year, because your VAT registration requirements follow the contract. Operators update them, and a change part way through the year changes how you count from that date onwards.

VAT registration requirements: principal vs agent decision table

The add-back rule comes from Notice 700/25. It tells drivers to add back amounts such as vehicle and radio rentals or agency charges that a firm deducts before paying them. The tips row also comes from the notice, which treats voluntary tips as outside the scope of VAT.

The grey area: service fees on a principal operator's statement

Many statements from principal operators show three lines: the passenger fare, a service fee and your earnings. Where the operator is the true principal, our view is that the fare is its sale and the gap is its margin, not a charge to you. Where the terms describe that fee as something you pay, the add-back rule may apply. That is a contract question, so have the agreement read before you rely on the lower figure.

Monthly bookkeeping checklist for VAT turnover

Run this checklist at the end of every month, not once a year, so you always know where you stand against your VAT registration requirements. The rolling test can be crossed in any month, and a busy winter can tip a driver over before the tax year ends.

1. List every income source for the month: each app operator, each local firm, direct private work and any other business income.
2. For each operator, record whether it acts as principal or agent, the date of the terms you checked and where you saved them.
3. For principal operators, take the amount paid for your services, then add back any vehicle rental, radio rental or charges deducted from you.
4. For agent operators, take the gross passenger fares before commission, not the net payout that reaches your bank.
5. Remove voluntary tips, and list them separately so the total can be traced back to each statement.
6. Add direct private and account work at the full amount you charged.
7. Add the month to your rolling 12-month total and drop the month that has fallen out of the window.
8. If the rolling total passes £90,000, or one strong month could take you over in the next 30 days alone, register within the GOV.UK time limit.
9. File the statements, the terms and your monthly working together, so you can show HMRC how you reached each figure.

Illustrative example: one driver, two operator models

This illustrative example uses an invented driver and our own round figures for the 2026/27 tax year. It is not based on any real person or operator.

Marcus drives in the West Midlands. Most of his work comes through an app operator that contracts with passengers as principal. He also takes evening jobs from a local firm that acts as his agent, plus a few airport runs he books himself. A typical month looks like this:

• App operator (principal): passenger fares shown on the statement £5,000; amount credited to Marcus for his services £3,700; nothing deducted from him.
• Local firm (agent): passenger fares £2,500; the firm keeps 15% commission (£375), so £2,125 reaches his bank.
• Direct airport runs: £450 charged to his own customers.
• Voluntary tips across all work: £120.

His correct monthly turnover is £3,700 plus £2,500 plus £450, which is £6,650. Over 12 similar months that is £79,800, below £90,000. The tips are left out, and the firm's commission is added back because it is the agent's fee to him.

Now look at the two common errors. If he counted the app operator's £5,000 of passenger fares, his total would be £7,950 a month, or £95,400 a year, and he would wrongly think he had to register. If he used only bank receipts from the local firm, he would understate by £375 a month, or £4,500 a year.

His headroom is £10,200 a year. A busy winter, more agent work or a switch of operator model could change the answer quickly. That is why he sorts his receipts monthly and rechecks his VAT registration requirements whenever an operator changes its terms.

What changes for agent operators from January 2028?

From 2 January 2028, according to a policy paper published on 29 October 2026, VAT law will treat larger agent operators as both buying the journey from the driver and selling it to the passenger. The agent then accounts for VAT on the full fare. The size threshold that brings an operator into scope is still to be consulted on.

HMRC's policy paper on VAT treatment of private hire vehicle operators says a new subsection will be added to section 47 of the VAT Act 1994. The deeming only applies to businesses whose annual fare turnover exceeds a threshold, with £50 million the lead option. Smaller businesses are expected to be unaffected.

For a driver working with an in-scope operator, your supply would be treated as made to the operator rather than to the passenger. The paper expects some drivers may register voluntarily, but it does not expect more businesses to have to register. It does not explain how drivers should value their own supplies for the threshold, so check GOV.UK for further guidance on VAT registration requirements before January 2028.

Separately, the consultation response confirmed that taxi and private hire supplies would be excluded from the Tour Operators' Margin Scheme (TOMS) from 2 January 2026, except where supplied with certain other travel services. That affects how some principal operators account for VAT on fares. It does not change how you count your own turnover.

Common VAT registration requirements mistakes and what each one costs

• Counting passenger fares from a principal operator's statement: you may register before you need to and take on VAT returns and VAT on your own supplies earlier than the law requires.
• Counting only net payouts from an agent firm: you can cross £90,000 without noticing. GOV.UK says that if you register late you must pay VAT on sales since the date you should have registered, and you may owe a penalty.
• Assuming the model from the city: an operator outside London may act as principal, and a local firm may act as agent. Check the terms, not the postcode.
• Ignoring a change of terms mid-year: count each period under the model in force at the time, or your rolling total will be wrong in both directions.
• Adding tips to turnover: this overstates your figure, because voluntary tips are outside the scope of VAT.
• Throwing away weekly statements: without them you cannot show HMRC how you reached your totals if it opens a compliance check.

How does VAT turnover fit with your Income Tax records?

Your VAT turnover and your Self Assessment income are linked but not identical. For Income Tax, you report your business income and then claim allowable costs, including operator commission. For VAT, you test turnover before any costs. Keep one set of records that feeds both, so the two sets of numbers reconcile.

Making Tax Digital (MTD) for Income Tax applies from 6 April 2026 to sole traders with qualifying income above £50,000, then £30,000 from April 2027 and £20,000 from April 2028, according to GOV.UK's MTD for Income Tax eligibility guidance. Our MTD guide for drivers explains the quarterly updates. The same monthly sort makes both jobs easier.

Mileage is a separate point. Claiming simplified mileage reduces your taxable profit, but it never reduces your VAT turnover. Our mileage log and records guide shows how to keep that log next to your operator statements.

Key terms

• Principal: the business that contracts with the passenger to provide the journey, and so makes the supply for VAT.
• Agent: a business that arranges bookings on a driver's behalf for a fee, leaving the driver as the supplier.
• Taxable turnover: the value of your sales that are not VAT exempt or outside the scope of VAT.
• Rolling 12 months: any 12 consecutive months, checked at each month end, not the tax year.
• Outside the scope: money, such as voluntary tips, that is not payment for a supply and is ignored for VAT.
• TOMS: the Tour Operators' Margin Scheme, a special VAT scheme now closed to most taxi and private hire journeys.
• PHV: private hire vehicle, licensed by your local council, or by TfL in London.

How UK Driver Accountants helps
