Professional conduct in relation to taxation (PCRT)

Helpsheets and support

Effective: 01 Mar 2019

Published: 06 Apr 2018 Update History

Professional Conduct in Relation to Taxation (PCRT) has been updated making it easier to navigate with a new digital structure. This edition is effective from 1 January 2023.

PCRT now consists of the fundamental principles and the standards for tax planning. Compliance with PCRT is mandatory for members advising on UK tax matters. Members must be familiar with and comply with PCRT and a failure to do so may result in disciplinary action.

Key points

  • PCRT is prepared jointly by seven professional bodies and associations, including ICAEW, whose members work in tax. The seven professional bodies are listed in para 1.11.
  • PCRT has been in existence for over 20 years and is regularly updated. It sets out the high ethical standards which form the core of the tripartite relationship between tax adviser, client and HMRC.
  • The latest PCRT responds to the government’s challenge to the professional bodies to take a greater lead in setting and enforcing clear professional standards around the facilitation and promotion of tax avoidance.
  • PCRT has been endorsed by HMRC as an acceptable basis for dealings between members and HMRC.

Help sheets

PCRT is supported by supplementary help sheets which replace Parts 3 and 4 of the 2017 edition of PCRT:

The help sheets represent guidance designed to help members apply the Fundamental Principles and Standards in their tax work. While not mandatory a member in a disciplinary case may be asked to explain why they did not follow the help sheet guidance. For example, a case might be brought against a member under the fundamental principle of integrity. As part of the investigation by the disciplinary body the member could be asked to explain why, as recommended in the ‘Dealing with errors’ help sheet, they had not advised their client to make good the tax underpayment which they had identified in the client’s tax affairs.

Additional support

ICAEW publishes a wide range of guidance for members. Here we additional support which should be particularly useful when read alongside PCRT.
