The Crucial Role of Human Expertise in Tax Appeals
in an era where Artificial Intelligence (AI) tools are increasingly accessible, their use in complex fields such as tax law is coming under scrutiny. The recent case of Bodrul Zzaman v HMRC serves as a poignant example.
Mr. Zzaman, representing himself at the First-tier Tribunal, relied on AI-generated arguments to contest a £2,501 High-Income Child Benefit Charge (HICBC) assessment for the 2018–19 tax year. However, the tribunal found that the AI-assisted arguments were either unclear or irrelevant, leading to the dismissal of his appeal.
The Case at Hand
In a notable decision from the First-tier Tribunal (FTT), a taxpayer's appeal against a penalty for failing to notify HMRC of a capital gains tax (CGT) liability was dismissed. The appellant, representing himself, submitted summaries of nine cases to support his claim of having a "reasonable excuse" due to mental health issues and ignorance of the law.
However, upon review, it was revealed that these cases were not genuine but were likely generated by an AI tool. The tribunal found that the cases bore hallmarks of AI-generated content, such as similarities to real cases with altered details and repeated phrases using American English spellings like "favor" instead of "favour" .
While the tribunal acknowledged that the appellant was unaware of the fictitious nature of the cases and did not intend to mislead, it emphasised that citing invented judgments is a serious issue. Such actions waste time and resources and can undermine trust in the legal system.
Reflections on AI in Tax Matters
The rise of AI tools has quite clearly revolutionised access to information, offering quick answers to often complex questions. However, this case highlights the limitations of AI in the nuanced field of tax law. AI models generate responses based on patterns in data but lack the ability to verify facts or understand context fully. Context, as we find time and time again, is often critical to fully understanding someone's tax liabilities.
At The Tax Faculty, we've encountered numerous instances where clients have approached us after receiving incorrect or misleading information from AI tools. These experiences really reinforce the importance of professional judgment and the ability to ask pertinent questions to understand an individual's unique financial circumstances.
The Value of Human Expertise
Tax law is intricate, with regulations that often change and require careful interpretation. Human experts bring some essential qualities to the table: critical thinking, contextual understanding, and ethical considerations—qualities that AI currently cannot replicate.
While AI can be a helpful starting point for general information, it should not replace professional advice, especially in matters as significant as tax liabilities. Relying solely on AI can lead to errors, as evidenced by the tribunal case, and potentially result in financial penalties or legal complications.
Conclusion
We understand the appeal of AI tools—they're accessible, fast, and can provide a starting point for understanding complex topics. For many, especially those navigating the intricacies of tax law for the first time, turning to AI can seem like a practical solution. However, as the recent tribunal case illustrates, AI lacks the nuanced understanding and contextual awareness that human professionals bring to the table.
At The Tax Faculty, we've seen first-hand how clients, after relying on AI-generated advice, have faced challenges due to inaccuracies or oversights. It's not about dismissing the value of AI but recognising its limitations.
We cannot stress enough, tax matters are deeply personal and often complex, requiring a tailored approach that considers individual circumstances.
