HMRC's whistleblower rules have changed, and directors can no longer assume only fraud is targeted. Chris Worden explains what these changes mean for UK company directors and how to protect yourself from unexpected investigations.
- HMRC whistleblower rules now target inconsistencies, not just fraud
- Anyone with access to your business can be a whistleblower
- Anonymous tips are now credible triggers for investigation
- Reports feed directly into HMRC's risk scoring systems
- Directors should tighten records and seek advice early
What Are HMRC Whistleblower Rules?
HMRC defines whistleblowers broadly. It's not just disgruntled employees or ex-partners. Anyone with access to your business information—current or former staff, contractors, accountants, suppliers, customers, or even competitors—can trigger a report.
What's Changed in 2026?
HMRC no longer needs proof of dishonesty to investigate. Whistleblower reports now feed directly into risk scoring systems. If a tip aligns with your data profile, HMRC may investigate, regardless of intent or evidence.
Who Becomes a Whistleblower?
- Current or former employees
- Contractors or bookkeepers
- Accountants or finance team members
- Suppliers, customers, or competitors
- Ex-spouses or business partners
Most whistleblowers don't see themselves as such—they may just be answering questions or protecting their own interests.
What Triggers an HMRC Investigation?
- Anonymous or named reports about inconsistencies
- Lifestyle not matching declared income
- Unusual cash withdrawals or undeclared income
- Off-the-books payments or repeated company closures
HMRC cross-references tips with your data. If patterns match, your risk profile increases and an investigation may follow.
How Does HMRC Investigate?
HMRC won't notify you of a tip-off. Instead, they may quietly review your records, rescore your risk, and start with routine checks—VAT, PAYE, corporation tax, or information notices. The whistleblower remains invisible, but the investigation is real.
How Can Directors Protect Themselves?
- Assume anything you say could be repeated—be careful with information.
- Keep records accurate and up to date. Reconcile, document, and file on time.
- Treat disengagement from accountants seriously—tidy up loose ends.
- Seek professional advice before responding to HMRC inquiries.
- If your business is struggling, seek insolvency advice early.
