Directors and advisers sometimes assume the corporate veil is a single, well-understood shield that either protects an individual entirely or gets "pierced" wholesale in egregious cases. The reality, confirmed authoritatively by the Supreme Court in Prest v Petrodel, is narrower and more technical than that, and HMRC's own practice reflects it: true veil-piercing is a doctrine HMRC almost never actually needs, because Parliament has given it better tools.

Introduction: Why This Doctrine Matters Less Than Advisers Assume
"Piercing the corporate veil" is one of the most commonly misused phrases in company law, frequently invoked loosely to describe any situation where a director ends up personally liable for something connected to their company, a Personal Liability Notice, a director disqualification, a transfer of assets provision. In truth, true common law veil-piercing is a narrow, specific doctrine, and HMRC's own practice confirms just how narrow: in the overwhelming majority of cases where HMRC wants to attribute a company's tax liability, or the consequences of a company's conduct, to an individual, it reaches for a specific statutory mechanism, a Personal Liability Notice, the Managed Service Company debt-transfer provisions, the transfer of assets abroad code, rather than asking a court to disregard the company's separate legal personality altogether.
Understanding why requires understanding what the Supreme Court actually decided in Prest v Petrodel Resources Ltd [2013] UKSC 34, the leading modern authority on the doctrine, and why its narrow holding, combined with the existence of purpose-built statutory alternatives, has left true veil-piercing a comparatively minor tool in HMRC's own practical toolkit, however often the phrase is invoked informally.
Prest v Petrodel: The Facts
The case arose from ancillary relief proceedings following the breakdown of Mr and Mrs Prest's marriage. A substantial property portfolio was held in the name of companies wholly owned and controlled by Mr Prest, rather than by him personally. The trial judge, seeking to satisfy a lump sum order made against Mr Prest, ordered the transfer of some of those properties from the companies to Mrs Prest, reasoning, in effect, that the corporate structure should be disregarded given Mr Prest's total control of the companies and his apparent attempt to use that structure to shield assets from the matrimonial proceedings. The companies themselves, as separate legal persons with their own creditors and obligations, challenged the order on appeal.
The Supreme Court's Holding: The Evasion Principle
The Supreme Court significantly narrowed the circumstances in which true veil-piercing is available. It held that the doctrine applies only where a person is under an existing legal obligation, liability, or restriction which they deliberately evade, or whose enforcement they deliberately frustrate, by deliberately interposing a company under their control. Both control and impropriety of this specific, evasion-focused kind must be established; mere use of a company structure to hold assets, even where the individual has complete control and the arrangement conveniently insulates those assets from a later claim, is not, by itself, sufficient. The impropriety must be specifically and causally linked to the use of the company structure to avoid or conceal the particular pre-existing liability in question.
Concealment Versus Evasion: The Key Distinction
The Supreme Court drew a sharp distinction between "concealment" cases, where a company structure is simply used to obscure who is really involved in a transaction or who really owns an asset, which do not require or justify veil-piercing at all because ordinary legal principles (such as identifying the true beneficial owner) can unpick the concealment without disregarding the company's separate personality, and true "evasion" cases, where the veil-piercing doctrine as narrowly defined actually applies. Many situations advisers instinctively label as veil-piercing candidates are, properly analysed, concealment cases capable of resolution through ordinary means, agency, trust, or simply establishing the true facts, rather than genuine evasion cases requiring the court to take the additional, more radical step of disregarding corporate personality itself.
Why Prest Also Confirmed Alternative, Non-Veil-Piercing Routes
Notably, Mrs Prest ultimately succeeded, but not through true veil-piercing. The Supreme Court found, on the specific facts, that the properties were held by the companies on a resulting trust for Mr Prest personally, meaning ordinary trust law principles, not the separate veil-piercing doctrine, made the properties available to satisfy his personal liability. This is the single most important practical lesson from Prest for tax practitioners: courts, and by extension HMRC, very often do not need to invoke true veil-piercing at all, because ordinary property, trust, and agency law frequently achieve the same practical result through more conventional, better-established legal routes.
HMRC's Preferred Statutory Attribution Tools
Rather than relying on the narrow, evidentially demanding common law doctrine, HMRC's practice, and Parliament's own legislative design, favours specific statutory attribution mechanisms tailored to particular scenarios: Personal Liability Notices under paragraph 19 of Schedule 24 FA 2007, attributing a company's deliberate-inaccuracy penalty to a director where the deliberate behaviour is attributable to them personally; the Managed Service Company debt-transfer provisions under Chapter 9 ITEPA 2003, transferring unpaid PAYE and NIC directly to directors and other specified persons where an MSC has failed to account for it; the transfer of assets abroad code, attributing income to a UK-resident transferor who retains the power to enjoy it despite formally routing it through an offshore structure; and director disqualification under the CDDA 1986, a regulatory rather than a debt-transfer mechanism but achieving comparable practical deterrence. Each of these has its own defined statutory test, its own burden of proof, and its own appeal route, generally more tractable for HMRC to establish and for a tribunal to apply than the fact-intensive, narrowly-drawn common law evasion test confirmed in Prest.
When True Veil-Piercing Still Arises in Tax Disputes
True common law veil-piercing remains relevant in tax disputes principally where none of the purpose-built statutory routes apply on the facts, for example where HMRC is pursuing enforcement of an existing debt or judgment against an individual who has, after the debt arose, deliberately routed assets through a newly interposed company specifically to frustrate enforcement, a scenario falling squarely within the Prest evasion principle rather than any of the statutory mechanisms designed for penalty attribution, PAYE debt transfer, or income attribution. Advisers facing this scenario should assess, rigorously, whether the facts genuinely establish deliberate evasion of an existing liability through deliberate use of the company structure, the narrow Prest test, rather than assuming a looser, more general sense of unfairness or convenient corporate structuring will suffice.
Practitioner Checklist, 6 Points When Veil-Piercing Is Raised in an HMRC Dispute
- Is there a genuine, existing legal obligation or liability that predates the company structure in question? Prest requires evasion of something that already existed, not merely inconvenient corporate structuring generally.
- Was the company interposed specifically to evade that pre-existing obligation? The causal link between the structure and the evasion is essential, not incidental.
- Does a specific HMRC statutory attribution route apply instead? Check PLNs, MSC debt-transfer, transfer of assets abroad, and director disqualification before assuming common law veil-piercing is the relevant analysis.
- Could this be a concealment case resolvable through ordinary means? Trust, agency, and beneficial ownership principles may achieve the practical result sought without needing true veil-piercing at all, as in Prest itself.
- Is control alone being conflated with impropriety? Complete control of a company is necessary but not sufficient; genuine evasion-linked impropriety must also be established.
- What does the timeline show? A company structure that predates the liability in question, used for genuine commercial reasons, is far harder to characterise as evasion than one interposed after the liability arose specifically to frustrate its enforcement.
Frequently Asked Questions
Can HMRC pierce the corporate veil to pursue a director for the company's tax debt?
In practice, rarely, because HMRC has purpose-built statutory routes (PLNs, MSC debt-transfer, director disqualification) that achieve similar outcomes without the narrow common law test. True veil-piercing under Prest v Petrodel [2013] UKSC 34 requires deliberate evasion of an existing legal obligation through the company structure, a demanding standard most HMRC scenarios don't need to meet.
What did Prest v Petrodel actually decide about piercing the corporate veil?
That the veil can only be pierced where someone deliberately evades an existing legal obligation by interposing a company they control. Where those conditions aren't met, other principles like trust or agency law may achieve a similar result without true veil-piercing, as happened on the actual facts of Prest itself.
Why does HMRC use statutory routes instead of piercing the veil?
Because Parliament has given HMRC specific tools (PLNs, MSC debt-transfer, transfer of assets abroad provisions) with clear statutory tests and appeal rights, generally more straightforward to establish and defend than the narrow common law doctrine.
Does a company holding assets for a director's benefit protect those assets from HMRC?
Not necessarily. Even without veil-piercing, assets held on trust for or beneficially owned by a director can be treated as available to satisfy that director's liabilities through ordinary trust and property law, exactly the basis on which Prest itself was ultimately decided.
