Can My Accountant Report Me to HMRC? – Understanding Your Rights

Updated: Jan 6

In UK tax law, a common concern for many individuals is whether their accountant can report them to HM Revenue and Customs (HMRC) for taxation irregularities. This delicate balance between client confidentiality and legal obligations has been the cause of much worry and confusion.

In this article, we aim to shed light on the circumstances under which a professional accountant might be obliged to disclose information about their client to HMRC, as well as the rights that individuals possess concerning their financial information.

Moreover, we will explore the triggers behind an accountant considering taking the step of reporting activity to HMRC and the potential consequences of such action.

The Duties and Obligations of Accountants to HMRC

An accountant's duty to HMRC is a critical aspect of their role, ensuring clients' financial affairs comply with legal obligations and regulations. This section evaluates the ethical and legal framework accountants adhere to, as well as the guidelines set by governing bodies and HMRC.

Acting within the law, accountants must abide by specific rules and responsibilities that protect their clients and the national interest. These legal obligations are shaped by various factors, such as:

  1. UK tax law and regulations

  2. Professional governing bodies, for example, the Institute of Chartered Accountants in England and Wales (ICAEW) or Association of Chartered Certified Accountants (ACCA)

  3. HMRC guidelines and requirements

Failure to uphold these duties and legal obligations can result in financial penalties for both the client and the accountant, along with potential damage to their professional reputation.

One of the primary duties accountants must adhere to is the accurate reporting of their clients' taxation issues. This involves providing clients with the necessary guidance on tax compliance and financial planning while maintaining complete and accurate records of all transactions and tax filings. Accountants are also responsible for identifying any tax irregularities and advising their clients on the appropriate course of action to rectify them.

National interest plays a significant role in shaping an accountant's obligations to HMRC. Accountants are expected to act in the best interest of UK taxpayers and the country as a whole by ensuring the correct amount of tax is collected. This, in turn, supports the allocation of funds to vital public services and infrastructure.

One way in which accountants contribute to the national interest is by adhering to anti-money laundering (AML) regulations. AML legislation is designed to prevent criminal activities such as tax evasion, terrorist financing, and money laundering. As part of their duty to HMRC, accountants must have robust AML policies in place, including:

  1. Conducting thorough client due diligence

  2. Submitting suspicious activity reports in cases where criminal activities are suspected

  3. Implementing internal controls to mitigate AML risks

  4. Regularly reviewing and updating their AML policies

In summary, an accountant's duty to HMRC revolves around acting within the law and following guidelines set by various regulatory bodies. By ensuring that clients adhere to tax regulations and delivering accurate reports, accountants play an essential role in maintaining the national interest in the UK tax system.

The Boundaries of Client Confidentiality and Reporting Requirements

In accounting, professionals must navigate the delicate balance between protecting their clients' interests and adhering to legal reporting requirements. This section examines the boundaries between client confidentiality and an accountant's duty to disclose information to Her Majesty’s Revenue and Customs (HMRC) regarding tax evasion and tax avoidance, providing clarity on the UK tax system and the ethical responsibilities that play a role in the accountant-client relationship.

What Constitutes Tax Evasion Vs. Tax Avoidance?

It is crucial to understand the difference between tax evasion and tax avoidance as they have drastically different legal and ethical implications.

  • Tax evasion is the illegal practice of under-reporting or concealing taxable income or gains, defrauding the UK tax system.

  • Tax avoidance, on the other hand, is the lawful use of tax reliefs, allowances, and exemptions to minimize a taxpayer's liability within the boundaries of the law.

Scenarios Where Accountants are Legally Required to Report

Accountants must adhere to strict reporting requirements while maintaining client confidentiality. Nonetheless, there are specific situations in which an accountant is legally obligated to break this confidentiality and report suspicious activity to HMRC. These scenarios include:

  1. Discovery of Deliberate Tax Evasion: When an accountant uncovers evidence suggesting that a client is deliberately evading taxes, such as under-reporting income, overstating deductions, or not declaring taxable assets, they are legally bound to report this to HMRC. This includes instances where clients have intentionally concealed or misrepresented financial information to reduce their tax liability.

  2. Detection of Money Laundering or Terrorist Financing: Accountants play a pivotal role in identifying and reporting financial transactions that may be linked to criminal activities. If there's reasonable suspicion or concrete evidence of money laundering or terrorist financing activities, accountants must report these findings to HMRC, adhering to the strict regulations outlined in anti-money laundering (AML) legislation.

  3. Identification of Fraudulent Behavior: When significant discrepancies in a client's financial records suggest fraudulent behavior, such as income misrepresentation or fake transactions, it is an accountant's legal duty to report these findings. This step is crucial in upholding the integrity of the UK tax system and safeguarding public funds.

  4. Involvement in Illegal Tax Schemes: If an accountant becomes aware of a client's participation in illegal tax avoidance schemes or transactions that deliberately contravene tax laws, they are obligated to report this activity. These schemes often involve complex structures designed to evade taxes and can significantly harm the national economy if left unchecked.

  5. Suspicions of Criminal Financial Activities: Accountants are required to act if they have suspicions or knowledge of any financial activities that may be criminal in nature, even if these activities fall outside the realm of taxation. This includes, but is not limited to, fraud, embezzlement, or insider trading.

  6. Advising on Tax Matters with Legal Implications: In scenarios where accountants provide advice that leads to tax evasion or avoidance, they must reassess their advice and report any illegal activities to the authorities. This responsibility underscores the need for accountants to stay abreast of current tax laws and regulations.

In each of these scenarios, the accountant's legal duty to report supersedes the usual expectations of client confidentiality. Accountants are trained to navigate these complex situations, ensuring that their actions align with both legal requirements and the high ethical standards set by professional accounting bodies.

Understanding Professional Ethics and Accountant Integrity

An integral aspect of the accounting profession is adhering to ethical standards and maintaining integrity. Accountants must abide by the guidelines outlined by the professional bodies that govern the industry, such as the Institute of Chartered Accountants in England and Wales (ICAEW) and the Association of Certified Chartered Accountants (ACCA).

These organizations establish codes of conduct to ensure that accountants act in the best interest of their clients while respecting the UK tax system's legal implications. Accountants are expected to uphold the following ethical principles:

  • Objectivity: Maintaining a neutral and unbiased perspective in professional judgement and decision-making.

  • Confidentiality: Safeguarding client information unless obligated by law or professional duty to disclose.

  • Professional Competence: Ensuring that accountants maintain their skillset and knowledge to provide high-quality services.

  • Integrity: Being honest, straightforward, and adhering to moral and ethical principles in all professional actions.

  • Professional Behaviour: Complying with relevant rules, regulations, and laws.

In conclusion, accountants must maintain client confidentiality while adhering to their ethical and legal obligations to the UK tax system. It is crucial for both clients and professionals to understand the boundaries between tax evasion and avoidance, the legal requirements for reporting to HMRC, and the ethical standards upheld within the accounting profession.


In summary, understanding the legal and ethical implications of an accountant's duty to report to HMRC is essential for both accountants and their clients in the United Kingdom. The delicate balance between client confidentiality and legal obligations is not only mandated by UK tax laws but also serves the greater national interest. Recognising the distinction between tax evasion and tax avoidance helps clarify the boundaries of legally acceptable strategies for reducing tax liabilities.

The article has shed light on specific scenarios where accountants are legally bound to break client confidentiality and report suspicious activities to HMRC. From detecting fraudulent activity to identifying large discrepancies in reported income, accounting professionals have a duty to adhere to both legal requirements and ethical standards.

Finally, it is important to appreciate the role that professional ethics play in the decision-making process of accountants when faced with potential HMRC reporting situations. Working within the legal framework of the UK tax system calls for its professionals to be guided by strong ethical principles and integrity. Should the situation necessitate further clarity, seeking professional advice is highly recommended to ensure compliance with the law and protect both accountants and clients from potential ramifications.
