Tax Investigation Service

HMRC Facts

HMRC’s latest figures reveal that the UK’s tax gap—the shortfall between the amount of tax that should be collected and what is actually received—stands at £39.8 billion, representing 4.8% of total tax liabilities.

Small businesses contribute the largest share of this gap, accounting for approximately 60%, or £23.9 billion. In addition, individuals, including high-net-worth and general taxpayers, are responsible for around 5% each, equating to £2 billion.

To close this gap, HMRC relies heavily on targeted and random Tax and VAT investigations.

Could You Be Next?

HMRC uses advanced technology to cross-reference data from a wide range of sources. Even if your returns are fully compliant, discrepancies or patterns can still trigger an investigation. Coupled with whistleblower reports and random checks, no taxpayer is exempt from scrutiny.

Be proactive—protect yourself before HMRC comes knocking.

The Hidden Costs of an HMRC Investigation

An investigation can stretch from months to years, often resulting in significant additional fees and emotional strain. Whether you are an individual or running an organisation, an investigation can consume valuable time and cause significant disruption.
