HMRC Issues Record Fines for VAT Fraud in 2025 – Are You At Risk?

Discover how landmark enforcement cases, multi-million-pound penalties and new security demands could hit you—and how to stay compliant.
HMRC has flexed its enforcement muscles in 2025 with record-breaking fines for VAT fraud. From a £47 million deregistration case to upfront security notices, the stakes have never been higher. Here’s how to spot the red flags—and shield your business before it ends up on the wrong side of a penalty.

1. HMRC’s 2025 Enforcement Surge: More Staff, Bigger Budgets

In 2022–23, HMRC’s Fraud Investigation Service grew to 4,956 staff, up from 4,244 in late 2021—a sign of a sustained crackdown on serious fraud. Meanwhile, the government earmarked £87 million over five years to partner with private debt collectors and recruited an extra 600 debt-management specialists to tackle an estimated £44 billion of outstanding tax debts.

Bottom line: HMRC now has unprecedented resources to uncover and punish VAT non-compliance.

2. Landmark ICSL Case: £47 Million Penalty and Deregistration

In May 2025, the Court of Session upheld HMRC’s decision to deregister Impact Contracting Solutions Ltd—denying a £47 million input-VAT claim after finding the business “knew or should have known” its supply chain was tied to fraud.

The ruling confirmed HMRC can strip VAT status from companies that facilitate carousel fraud, even if some supplies appear legitimate.

Warning: Any association—direct or indirect—with fraudulent chains can cost you tens of millions overnight.

3. Notice of Requirement: Up-Front Security Demands

Beyond traditional penalties, HMRC now issues Notices of Requirement to demand security deposits covering future VAT, PAYE, and NIC liabilities.

These legally binding demands can run into hundreds of thousands of pounds, crippling cash flow if ignored—and failure to comply risks personal liability for directors.

Pro tip: Early engagement with HMRC and timely appeals are vital to contest excessive or unwarranted security notices.

4. Penalty Rates: Up to 100% of the Unpaid VAT

HMRC’s civil penalties for VAT inaccuracies scale by intent:

• Careless mistakes: up to 30% of the under-declared VAT.
  
  

• Deliberate non-disclosure: up to 100% of the tax owed.
  
  

Moreover, HMRC can investigate up to 20 years back for deliberate fraud, keeping even historic transactions under scrutiny.

Key takeaway: The maximum potential bill can double your original VAT liability—and stretch back two decades.

5. Are You at Risk? Common Triggers & Red Flags

Watch out for these high-risk scenarios:

• Unusual supplier chains or inconsistent invoicing volumes—classic signs of MTIC fraud.
  
  

• Failing the “knows or should have known” test under the Kittel principle.
  
  

• Late or incorrect returns under Making Tax Digital, which now incur stepped penalties escalating to 10% p.a. on overdue balances.
  
  

Self-audit tip: Regularly review your VAT registrations, run supplier due-diligence checks, and reconcile returns to purchase/sales ledgers.

6. Mitigation Strategies: Voluntary Disclosure & Robust Controls

Here’s how to reduce your exposure:

• Voluntary Disclosure under the Contractual Disclosure Facility (COP9) can reduce penalties and avoid criminal prosecution—if you act before an HMRC visit.
  
  

• Tighten procurement controls: vet new suppliers, validate VAT numbers via the VIES system and document your due diligence.
  
  

• Use tech tools: automated checks that flag invoice anomalies or unexpected reclaims can prevent costly oversights.
