A director parks two Teslas and a Porsche on his driveway. He tells HMRC they’re pool cars — no benefit in kind, no tax. His justification? A conversation with a tax inspector in 1993. The tribunals disagreed, with costly consequences. Maywal Ltd v HMRC is a reminder that informal comfort doesn’t beat statute — and that “pool car” is a technical term with four conditions, every one of which has to be met.
What the law actually says
The pool car exemption is in section 167 of the Income Tax (Earnings and Pensions) Act 2003 (ITEPA 2003). For a car to be a pool car in a given tax year, four conditions must all be satisfied:
- It is made available to, and actually used by, more than one employee.
- It is not ordinarily used by one employee to the exclusion of the others.
- Any private use is merely incidental to business use.
- It is not normally kept overnight on or near an employee’s residence, unless those premises are the employer’s business premises.
All four. Meeting three doesn’t qualify. And the conditions are tested against what actually happens, not what an old letter or a historical chat with an inspector might once have said.
The Maywal facts
Maywal Ltd ran a fleet of twelve cars including two Teslas and a Porsche, kept overnight at the company’s registered office — which was also the director’s home. Back in 1993, the company had discussed the arrangement with an HMRC inspector and come away with an understanding that the cars could be treated as pool cars. That was the basis for its tax affairs for three decades.
On investigation, HMRC found the cars had been predominantly used for private journeys, with no meaningful restriction on private use. The directors didn’t attempt to demonstrate compliance with s.167 — they relied on the 1993 conversation.
The First-tier Tribunal held that the vehicles failed the pool car conditions as a matter of fact. The Upper Tribunal confirmed that the statutory position still applied, regardless of the earlier discussion. The cars were subject to full company car benefit treatment — income tax on the drivers and Class 1A employer’s NI on the company.
Three lessons for owner-managers
Informal comfort from HMRC is not a safe harbour. A conversation, an old letter, a concession granted years ago — none of it displaces the statute when facts change or a later officer reopens the position. Pool car status is tested year-by-year against s.167; it isn’t “granted” and banked.
The “office is also my home” fact pattern is particularly dangerous. Where the employer’s premises and the director’s home share an address, HMRC will look at how the car is actually used; the overnight location alone rarely saves the exemption. That was the fatal flaw in Maywal.
“Incidental” private use means what HMRC’s manuals say: minor use arising from the business use itself (giving a colleague a lift home because the car was out on a job). It does not mean “a bit of personal driving at weekends that didn’t feel like much”. A car driven home every night isn’t incidental — it’s primary.
What a defensible pool car policy looks like
For clients running fleets or even one or two shared vehicles, a compliant policy usually includes:
- A written statement of the four s.167 conditions, issued to every driver with pool car access and signed to acknowledge.
- A journey log for every trip — date, driver, start and end location, purpose, mileage. The log is what rescues you in an enquiry; without it HMRC can draw adverse inferences from fuel cards, insurance and tracker data.
- A written prohibition on private use, with clear consequences for breach.
- An overnight parking rule: pool cars stay at business premises, not at drivers’ homes. Any exception is logged with a documented business reason.
- An annual review against how the fleet is actually used, with revisions when practice has drifted from policy.
The takeaway
Pool car status is a fragile exemption by design — it lives or dies on the facts each year. Historical comfort is no substitute for a current-year compliant policy and live evidence of use. If you’re running vehicles on the basis that “HMRC has always been fine with it”, Maywal is the case worth reading.
