Ethical behaviour

Ethical compliance is key to maintaining public confidence in the accountancy profession. All AAT members are bound by AAT’s Code of Professional Ethics (PDF)

Our Code of Professional Ethics is based on the IESBA Code of Ethics for Professional Accountants and sets out the five fundamental principles with which all AAT members must comply. In addition, AAT publishes supporting guidance on topics of specific interest:

AAT independence provisions relating to review and assurance engagements

Sections 290 and 291 provide specific guidance on independence requirements for licensed members who perform review and assurance engagements.

The full provisions relating to this can be found within the AAT Code of Professional Ethics: independence provisions relating to review and assurance engagements (PDF).

Professional conduct in relation to taxation (PCRT)

Professional members working in tax must comply with the fundamental principles of behaviour outlined in Professional conduct in relation to taxation (PDF). This guidance has been produced by AAT, ACCA, ATT, CIOT, ICAEW, ICAS and STEP, and has been effective since 1 March 2019.

AAT members must be fully aware of the ethical implications of anti-corruption legislation in their profession as well as the implications of laws such as the UK Bribery Act 2010. It is important to note that under the Act, a bribe does not have to be money; it can also include excessive and disproportionate gifts or hospitality. 

The Bribery Act

The Bribery Act came into force on 1 July 2011. The aim of the Act is to promote anti-bribery and corruption practices among UK businesses. The Act pulls together some existing offences under old UK anti-bribery and corruption laws and creates a new offence of failure by an organisation to prevent bribery.  

The main offences covered under the Act are:  

  • offering, promising, or giving a bribe  
  • accepting a bribe  
  • bribing a foreign public official  
  • failure by an organisation to prevent bribery by employees or associates.


Members, particularly members in business or in public practice will need to ensure they have appropriate polices and controls in place to safeguard themselves and their business from the risk of bribery. An anti-bribery policy should be appropriate to the level of risk your business faces and shared will all staff (and that they understand). As a minimum it should include:

  • an approach to reducing and controlling the risks of bribery
  • rules on accepting gifts, hospitality, or donations
  • directions on how to conduct your business such as negotiating contracts
  • guidance on avoiding or stopping conflicts of interest.

Failure to comply with the Act  

The Act creates strict liability offences, so ignorance to the actions of employees and associates is not a defence. The Act gives the courts the powers to impose penalties including unlimited fines and prison sentences of up to ten years.

Protect – speak up, stop harm

Whistleblowing is when an individual raises a concern about a danger, risk, malpractice, or wrongdoing within an organisation. The concern may be raised internally or externally.

As a member you might see something unethical or become aware of behaviour which concerns you and you need to decide whether to speak up and raise your concerns. This might be informing your line manager or someone else in authority, or whistleblowing to an external body.   

In the UK Protect (formerly Public Concern at Work) are leading experts in whistleblowing. They operate a free, confidential advice line about misconduct at work to anyone who is not sure whether or how to raise their concerns. Protect aims to help enquiries to identify how to best raise the concern while minimising any risk to the whistleblower and maximising the chances for misconduct to be properly addressed

For whistleblowing advice you can call +44 (0)20 3117 2520, email or visit their website.

Members also have statutory obligations to report to the National Crime Agency under the anti-money laundering legislation. This requirement is discussed in AAT’s AML Whistleblowing policy and guidance
