Putting you first

Patrick Cannon

Patrick Cannon LL.B, BCL (Oxon) CTA (Fellow) is a tax barrister licensed by the Bar Standards Board to accept direct access work and conduct litigation. He was previously a practising solicitor before being called to the Bar and is a former council member of the Chartered Institute of Taxation. Professional, licensed access and/or lay clients (as appropriate) may contact Patrick to obtain a quotation for legal services.

Patrick advises on and appears in civil and criminal tax disputes with HMRC, challenges to tax avoidance schemes and action against professional and other advisers who mis-sold aggressive tax avoidance schemes now subject to APNs and Follower Notices.

He is also a leading specialist in Stamp Duty Land Tax and related tax issues and his published works include the annual Tolley’s Stamp Taxes and Key Haven’s GAAR: A Practical Approach (3rd ed April 2018).

Patrick Cannon’s pricing model is that he works on the basis of fixed fees for each stage of a job, agreed in advance.

Timescales to complete a piece of advice or work can be estimated at the request of each client, but this could be affected by factors such as the time taken by the court or tribunal to
offer a hearing date, the availability of relevant documents, information or witnesses, the time taken by HMRC to respond to correspondence and also my availability due to client or other work commitments, holiday or illness.


It’s time to recognise neurodiversity at the Bar properly and I am proud to champion the organisation Neurodiversity in Law whose purpose is to promote and support neurodiversity within the legal professions and eliminate the stigma often associated with people who think differently.
