What is a tax investigation?

When HMRC make enquiries into your tax affairs.

Many tax investigations are random. Unusual fluctuations, undisclosed accounts and random spending can also prompt an enquiry into individuals and companies.

The taxman has the power to inspect business documents and assets at your premises, ask for documents and information, make unannounced inspections and go back six years to investigate matters, and in some cases even twenty years.

Disruptive, intrusive and expensive – when HMRC investigates it can drag on for a year or more, creating mounting costs and rocketing stress levels.

Last year HMRC collected £34.1bn from tax investigations and enquiries.

HMRC can target anyone who submits a tax return and their highly efficient ‘Connect’ software is accessing and trawling through financial information right now. The powerful system can trace even the smallest discrepancy in spending or earnings, prompting an investigation into individuals and businesses.

HMRC may have you in their sights…
