Tax Investigation

Established in 1997, XON Law has always been a specialist in the defence of serious white-collar crime.

Historically, we have been instructed in the defence of many of the highest-profile financial crime cases, including complex tax evasion, Ponzi schemes, carbon trading, insider dealing, and financial markets manipulation.

We frequently provide immediate counsel and representation to clients who are the subject of search and seizure by investigating agencies. Our team can attend the scene of a search to ensure compliance with strict statutory guidelines and, where appropriate, to negotiate the scope of the search to minimise disruption to your business or personal life.

Our track record includes successfully challenging the validity of search warrants in the High Court, providing a robust defence when you need it most.

Facing a tax investigation can be a daunting and complex process with significant professional and financial risks. We provide strategic legal guidance to individuals and companies subject to scrutiny by tax authorities, including HMRC. We work to manage all communications with investigators and build a robust case from the outset, aiming to achieve a swift and favourable resolution. Our expertise ensures your interests are robustly protected throughout the entire investigation.
