Phil has always struck me as being both professional and expert in his field

    Phil has always struck me as being both professional and expert in his field. I attended a number of meetings with him when we were both at Chiltern and was always impressed by his commercial approach so much so that I have recommended him as a speaker at profile events for accountants. I have followed his subsequent career and am pleased to see that he has gone from strength to strength.

Bloomsbury Professional
Dealing with HMRC Business Tax Enquiries - The second edition of this popular book (formerly Dealing with Revenue Enquiries) provides a complete guide to the law and practice of HMRC direct tax enquiries, and now covers the increasingly important area of tax credit enquiries. Following the enquiry process from start to finish, it includes both corporate and personal tax investigations. This is a fast changing area of practice, and the book covers the very latest developments, such as: the substantial amendments to HMRC's Enquiry Manual, including, in particular, a change of attitude towards the imposition of penalties in aspect enquiries; the creation of HMRC Regional Appeals Units and the impact on the conduct of enquiry work; and reform of the Hansard practice for dealing with cases of suspected serious fraud.

How did I get here? 


Continuing our How Did I Get Here? series, Phil Berwick explains how he went from the Inland Revenue to head of the National Tax Investigations Team at Tenon.

Current job title

Director of Tax Investigations at Tenon.

Tenon is a national accountancy and business advisory practice which works with small and medium sized businesses. Tenon provides clients with expertise in Business Services, Tax, Financial Services, Corporate Finance, Recovery, Outsourcing and Forensic Accountancy.

Describe your initial training within the profession

I am an ex-tax inspector and not a qualified accountant. I successfully passed the ATT examination in 1994, while still in the Inland Revenue. I left to join the profession in 1995, and passed the ATII (now CTA) examination in 1997.

What positions have you held?I started in the Inland Revenue as a Tax Officer (Higher Grade) and was subsequently promoted to inspector. After leaving the Inland Revenue, I joined the tax investigation team at Casson Beckman, where I stayed until 1997. I then joined Ernst and Young before moving to Williams Jeffrey Barber International (now Chiltern plc) in 1999 as a Senior Consultant. I joined Tenon as head of their National Tax Investigation Team in June 2005.

Since joining the profession, I have specialised in defending clients under investigation by the Inland Revenue, primarily Special Compliance Office investigations.

What advice would you give someone thinking of entering the profession?

Be focussed on what you want to achieve. Hard work and commitment can go a long way to achieving your ambitions.

Is there a significant event you can tell us about which had an impact on your career?

There have been several, but the most important was leaving the Inland Revenue in 1995. I enjoyed my time as an inspector, but the move to the profession enabled me to broaden my skill-base.

My experience in the Inland Revenue has been invaluable in dealing with clients, and assisting them in their dealings with the inspector.

What is your overall view of the finance industry and the people in it?

As with all walks of life, the profession contains a mixture of personalities. I have been very fortunate to work with some interesting and knowledgeable people.
