About me

I am a tax adviser, currently living in Cambridge with my wife Claire (we got married in June 2009). At work, I specialise in international tax planning, and am the author of Tolley's International Tax Planning published by LexisNexis.


My full CV is available below.


I use Toodledo to manage my actions list, and follow (loosely) the Getting Things Done productivity method.


Outside of work, my hobbies include reading, electronics, skiing, Italian, computers, Meccano, bookbinding and cycling.


The latest edition of Tolley's International Tax Planning 2015 / 2016 was published latest year.


I am a Consulting Editor for Tolley Guidance and have contributed most of the international guidance notes to the corporate tax module.


I also write regularly for Tax Journal, and some of my articles include:
