Rumours that the Nigerian government is silently monitoring every citizen's bank account have circulated for years, intensifying each time tax policy shifts. Many taxpayers believe the Federal Inland Revenue Service operates a real-time surveillance system capable of flagging every transaction. The reality, grounded in existing legislation, is considerably more measured.
The principal legal framework comes from the Finance Act amendments and the Federal Inland Revenue Service (Establishment) Act. Under Section 28 of the FIRS Establishment Act, the Service may appoint any bank as a collecting agent for tax purposes and may request information relating to specific taxpayers. This is not a blanket licence. The law requires that such requests be tied to identifiable taxpayers, typically those already under audit or investigation, and must follow due administrative process.
Further provisions were introduced through the Finance Act 2019, which empowered the FIRS to access taxpayer banking information where relevant to determining tax liability. The 2020 Finance Act expanded this further, reinforcing the obligation of financial institutions to comply with information requests. However, these provisions do not establish a continuous monitoring apparatus. The FIRS does not have a live dashboard tracking all Nigerian bank accounts in real time.
Nigeria also participates in the Automatic Exchange of Information framework under the Common Reporting Standard, administered by the Organisation for Economic Co-operation and Development. Through this multilateral mechanism, Nigerian authorities can receive financial account information on residents holding assets abroad, and reciprocally share information with treaty partners. This system operates annually, not continuously, and applies predominantly to reportable accounts exceeding specified thresholds.
What banks are required to do, under Know Your Customer and anti-money laundering regulations, is maintain records and report suspicious or high-value transactions to the Nigerian Financial Intelligence Unit. That obligation falls under the Money Laundering (Prevention and Prohibition) Act and is distinct from tax monitoring, though information may be shared across agencies where legally permitted.
For the ordinary taxpayer with compliant filings, the likelihood of having bank accounts scrutinised by the FIRS without cause remains low. The real risk sits with those who have unreported income, unexplained wealth, or significant discrepancies between lifestyle and declared earnings. In such cases, the FIRS can and does invoke its statutory powers to obtain banking records as part of a formal investigation.
The distinction is critical: targeted, lawful access is not the same as wholesale surveillance. Taxpayers are better served by ensuring their filings are accurate and complete than by fearing an omnipresent government eye that does not, under current law, exist.
