Where a practitioner suspects that an irregularity may have occurred resulting in an underpayment of tax, they should discuss this with the client to remove or confirm the suspicion. The member should take into account the fact that they may not be aware of all the facts and circumstances and may not be able to reach a conclusion.
A practitioner must act correctly from the outset and keep sufficient, appropriate records of discussions and advice. When dealing with irregularities, they should:
- give the client appropriate advice
- if necessary, so long as they continue to act for the client, seek to persuade the client to behave correctly
- take care not to appear to be assisting a client to plan or commit any criminal offence or to conceal any offence which has been committed
- in appropriate situations, or where in doubt, discuss the client’s situation with a colleague or an independent third party (having due regard to client confidentiality).
Although a member is not under a duty to make enquiries to identify irregularities which are unrelated to the work which they have been engaged to undertake, if they do become aware of any irregularity in a client’s tax affairs, they should consider the following:
1. The size of the tax effect
In the opinion of the accountancy professional bodies, in Professional Conduct in Relation to Taxation paragraph 5.17, it is reasonable for a practitioner to take no steps to advise HMRC of isolated errors where the tax effect is no more than minimal – say up to £200 – as these will probably cost HMRC and the client more to process than they are worth to the Exchequer.
2. Client’s authorisation required to disclose the irregularity
If the client is unwilling to make a full disclosure to HMRC, the member should ensure that their conduct and advice are such as to prevent their own probity being called into question.
It is essential therefore to advise the client, in writing, setting out the facts as understood by the practitioner, confirming to the client their advice to disclose and the consequences of non-disclosure.
If, despite being fully advised of the consequences, the client still refuses to make an appropriate disclosure to HMRC, the member must:
- cease to act
- if relevant, inform HMRC of their withdrawal
- consider withdrawing reports which they have previously signed in respect of the client
- consider whether a money laundering report should be made to the money laundering reporting officer (MLRO) or National Crime Agency (NCA)
- consider carefully their response to any professional enquiry letter (also known as professional clearance letter).
