Professional Ethics for Accountants

All AIA members commit to the highest ethical standards through the AIA Constitution, which includes our comprehensive Code of Ethics.

Five Principles Under our Code of Ethics:

Integrity

Be honest and straightforward in all professional and business relationships.

Objectivity

Make decisions free from bias, conflicts of interest, or undue influence.

Professional Competence and Due Care

Maintain up-to-date knowledge and skills to deliver high-quality service.

Confidentiality

Protect sensitive information and only disclose it when legally or professionally required.

Professional Behaviour

Follow all relevant laws and regulations, and avoid actions that could damage the profession’s reputation.

 

The Code can be accessed here.

Acting in the Public Interest

AIA’s rigorous membership standards and disciplinary procedures help protect the public and uphold confidence in the profession.

As an accounting professional, you are expected to:

  • Use sound judgement and expertise to serve the public interest
  • Apply ethical principles to meet client needs without compromise
  • Manage risk responsibly
  • Treat all parties fairly and with respect

 

If a member’s conduct falls short of these standards, AIA will investigate and take appropriate action.

Professional Conduct in Relation to Taxation

AIA has adopted the Professional Conduct in Relation to Taxation (PCRT) —a recognised standard for ethical tax advice in the UK.

This guidance outlines:

  • The responsibilities of tax advisers to provide clear, accurate advice
  • The reputational and practical implications of tax decisions
  • Expert commentary on common and complex tax scenarios

 

PCRT has been recognised by UK courts as the benchmark for professional behaviour in taxation.

 

Other Resources

The IBE Say No Toolkit developed by the Institute of Business Ethics (IBE), is a practical decision-making tool that helps employees navigate ethical challenges in the workplace.

It offers clear, immediate guidance to support ethical choices—especially when facing pressure or uncertainty.

When to Use the Toolkit

The Toolkit helps employees decide whether to say YES or NO in situations such as:

  • Being offered a gift or hospitality
  • Being asked to make a facilitation payment
  • Facing a potential conflict of interest

 

Why it Matters

  • Simple and effective – Offers step-by-step guidance in real time
  • Widely applicable – Suitable for organisations of all sizes and sectors
  • Supports ethical culture – Empowers employees to act with confidence and integrity

 

By using the Say No Toolkit, your team can make informed decisions that align with your organisation’s values and ethical standards.

The International Ethics Standards Board for Accountants (IESBA) sets globally recognised ethics standards for professional accountants. These include essential guidance on auditor independence and help ensure consistent, high-quality ethical practices across the profession.
