In an update published by Channels TV, Nigerian commercial banks have begun the full enforcement of mandatory Tax Identification Numbers (TIN) for both new and existing account holders. This policy, which stems from the new tax reforms, requires every individual and business to link their bank accounts with their tax records. Failure to comply will result in restricted access to banking services, including transfers and withdrawals, as the government seeks to widen the tax net and track illicit financial flows.
The Central Bank of Nigeria (CBN) and the FIRS have collaborated on a unified platform that allows for real-time verification of tax IDs. Bank officials have urged customers to update their records immediately to avoid being locked out of the financial system. The policy is also aimed at identifying high-net-worth individuals who have previously evaded taxes while moving large sums of money through the banking sector.
The enforcement was also documented by The Nation and Vanguard. The Nation reported that “banks have seen a surge in customers visiting branches to link their TINs,” while Vanguard noted that “the move is expected to significantly boost the government’s non-oil revenue.”
Echotitbits take:
This is the “no-escape” phase of Nigeria’s tax reform. By linking TIN to bank accounts, the government can now monitor income versus lifestyle in real-time. Watch for a rise in fintech usage and “under-the-mattress” cash holdings as some small businesses try to avoid the digital tax footprint.
