Tax authorities around the world are turning to automation, data analytics, and artificial intelligence to strengthen compliance and streamline audit processes. Nigeria is no exception, with the Federal Inland Revenue Service (FIRS) and state internal revenue services progressively adopting digital tools to scrutinise taxpayer records, flag discrepancies, and generate assessments.
These digital audit systems—sometimes described colloquially as "robot auditors"—operate by cross-referencing taxpayer data from multiple sources, including bank records, corporate filings, customs data, and third-party returns. The technology can process vast datasets far more quickly than human auditors, identifying anomalies and potential under-reporting that might otherwise go unnoticed.
However, the shift toward automated enforcement raises important questions about taxpayer rights. Traditional audits involve human discretion, dialogue between tax officials and taxpayers or their representatives, and opportunities for clarification before assessments become final. An algorithm-driven process may lack these safeguards, potentially issuing determinations without adequate context or affording taxpayers a meaningful opportunity to respond.
Key concerns include transparency of the audit criteria, the right to be heard before an adverse finding, the accuracy of data feeds that automated systems rely upon, and the availability of effective review or appeal mechanisms when taxpayers dispute machine-generated assessments. There are also questions about whether the legal framework governing tax administration in Nigeria adequately contemplates the use of artificial intelligence and automated decision-making.
For taxpayers, the implications are significant. Businesses and individuals alike may receive tax demands based on algorithmic analysis they neither understand nor have had the chance to challenge at the formative stage. This creates both compliance risk and potential injustice if the underlying data or logic is flawed.
Tax professionals and legal practitioners are increasingly called upon to engage with these systems, understand their operation, and advocate for procedural fairness. As digital audits become more prevalent, the balance between administrative efficiency and taxpayer protection will remain a critical issue for Nigeria's tax ecosystem.
