Patrick Cannon is a leading London tax barrister with over 30 years of experience successfully representing clients being investigated by HMRC for civil tax enquiries and criminal tax investigations.

Patrick can help you with COP 8 and 9 enquiries, challenging tax information notices and undertaking tax judicial reviews. Patrick can also provide advice and assistance, or legal representation if HMRC have opened a tax investigation into your tax affairs.

Patrick specialises in criminal or civil tax investigations. If a civil tax enquiry by HMRC grows into a criminal tax investigation, then Patrick Cannon will be able to handle this transition. And on the other hand, if a criminal tax investigation by HMRC is successfully downgraded to a civil tax enquiry, Patrick Cannon can advise and offer you representation, at any stage.

Civil and criminal tax investigations can result in loss of reputation or livelihood unless handled correctly, so rest assured Patrick is devoted to handling each case with the utmost care.

If HMRC have accused you of tax evasion, tax fraud or inaccuracies in your tax affairs, and are attacking you unfairly or unreasonably then Patrick Cannon will defend you fearlessly. And in cases where HMRC’s focus on your tax affairs is justified, Patrick will seek to manage your civil tax investigation in order to obtain a sensible settlement of the matter for you with HMRC as discreetly, inexpensively and as quickly as possible.

While Patrick often acts for clients who instruct him via professional accountants and solicitors he is also authorised by his regulator for Public Access and to conduct litigation. This means that he can accept instructions direct from clients without the client going through a solicitor or accountant thus saving professional fees. Patrick can correspond direct with HMRC and others on your behalf in serious HMRC tax investigations also.

Fixed fees agreed with Patrick’s clerk in advance for each piece of work, compared with traditional open-ended hourly rates still favoured by many advisers, brings financial certainty for you.
