Ethical dilemmas involving tax issues were identified by members of the American Institute of Certified Public Accountants as posing the most difficult ethical problem for them (Finn et al., Journal of Business Ethics 7(8), pp. 607-609, 1988). The KPMG tax shelter fraud case proves that the tax profession has not gone untainted in the age of numerous accounting and corporate scandals, such as the Enron d,bA cent cle (Sikka and Hampton, Accounting Forum 29(3), 325-343, 2005). High-profile scandals serve to highlight the problems caused by differences in ethical judgement among accountants and tax practitioners and the issue of ethics has been brought publicly to the forefront of the profession. Nevertheless, the nature and dimension of ethical issues in tax practice have been largely unexplored (Erard, Journal of Public Economics 52(2), 163-197, 1993; Marshall et al., Journal of Business Ethics 17(12), 1265-1279, 1998; Frecknall Hughes, Unpublished PhD Thesis, The University of Leeds, 2002). This research aims to contribute to the debate on ethics in tax practice by reporting interview data on tax practitioners' perceptions of ethics in the jurisdictions of Ireland and the United Kingdom and exploring the link or equation of ethics with risk management.
