Perceptions of auditor independence have become fundamental to public confidence in financial reporting and audit assurances. The lack of research on this issue in the Hong Kong auditing environment motivates the empirical study. The enactment of appropriate auditing standards in the marketplace could suitably serve the public interest and regulate the profession. Results show that provision of non-audit services (NAS) and high competition could have a negative affect on perceptions of independence. There is no difference in perception ratings between CPA-certified auditors and trainee auditors. Auditors perceive that NAS provision has a significantly more adverse influence on independence than laypersons do. Results imply that the theory of audit expectation gap still exists in the post-Enron audit environment. The Hong Kong regulatory body should consider professional reforms, such as the prohibition of NAS. Internationally, the study would be of interest to those doing business in China and Hong Kong.
