If you are a business owner or director operating in sectors like labour supply, payroll, electronics, or green tech, the landscape of tax investigations has shifted beneath your feet.
For years, many directors believed that if a supply chain problem arose—specifically regarding VAT or “Missing Trader” (MTIC) allegations—the worst-case scenario was a corporate insolvency. The company would fold, and the director would move on.
In 2025, that assumption is dangerous. HMRC’s Fraud Investigation Service (FIS) has updated its playbook. They are no longer just looking at the company; they are looking at you.
The New Battlefield: Personal Liability Notices (PLNs)
Recent legal precedents in late 2025 have emboldened HMRC. We are seeing a sharp rise in Personal Liability Notices (PLNs). This allows HMRC to transfer a company’s tax debt to its directors if they can prove the director “knew or should have known” that their transactions were connected to fraud.
The distinction between a successful defence and personal financial ruin is becoming increasingly technical.
- The Warning (The Powar Case): In the recent Powar decision, the Upper Tribunal confirmed that directors can be held personally liable if they turn a blind eye to “commercial anomalies.” If your margins are too consistent, or your deals look “too good to be true,” your personal assets could be on the line.
- The Defence (The Red Rose Case): Conversely, the Red Rose Payroll victory proved that you could win. The Tribunal ruled that “inadequate due diligence” alone is not proof of fraud. But to achieve this result, the taxpayer had to demonstrate immediate, decisive action and commercially sound behaviour.
What Does “Action” Look Like?
Many clients come to us after receiving a “Knocker” letter or a “Nudge” regarding their supply chain. Often, they have tried to handle it themselves, believing that handing over a folder of due diligence documents is enough. It is not.
HMRC does not want to see your checklists; they want to test your commercial judgment.
- Can you explain why you trade with a specific supplier?
- Do you have a paper trail showing you asked the tough questions?
- Did you freeze payments the moment you had a suspicion?
If you cannot answer these questions with legal precision, you are vulnerable.
