Collier was, until recently the global leader of PwC's banking tax practice.

He has been deeply involved in tax policy issues for some time and leads the firm’s work on the tax policy issues with the supranationals, such as the OECD and UN. He has been closely involved in a number of the many recent changes from the OECD, including the OECD’s work on international financial centres (initially with the Harmful Tax Practices work stream, latterly with the work on transparency and exchange of information). He has also participated actively in the OECD’s work on the more important tax treaty issues (such as the work streams relating to permanent establishments and beneficial ownership) and the work of the FTA and the OECD on the development of "co-operative compliance”.

He is centrally involved in the BEPS project (on which he leads the PwC global response) and has been asked to participate or contribute to ongoing OECD work on various occasions.  He has recently been in discussions with the Chinese tax authorities on BEPS.

Collier completed academic research in taxation at the Universities of Cambridge (LL.M. thesis on transfer pricing) and University of London (Ph.D. thesis on double tax treaties). Richard is a Chartered Accountant and barrister at law. He writes and lectures extensively on tax policy and financial sector tax matters.
