In a sweeping digital overhaul that will transform the relationship between every Nigerian and the state, the Federal Inland Revenue Service (FIRS) has confirmed a seismic policy shift: your National Identification Number (NIN) is now your official Tax Identification Number (TIN), merging identity and tax profiles into a single, unbreakable government file.
The announcement, part of a public awareness campaign for the new Nigeria Tax Administration Act (NTAA) set to take effect in January 2026, mandates the use of a Tax ID for specific financial transactions—a requirement the FIRS insists has existed since 2019 but is now supercharged by digital integration. For registered companies, the Corporate Affairs Commission (CAC) number will serve the same purpose, effectively ending the era of multiple, separate tax IDs.
‘You Do Not Need a Physical Card’: The Era of the Digital Tax Shadow
The FIRS was explicit: this is a digital leash, not a plastic card. “You do not need a physical card, as the Tax ID is a unique number linked directly to your identity,” the agency stated. The move aims to “simplify taxpayer identification, eliminate duplication, prevent tax evasion, and ensure fairness”—government-speak for a high-tech dragnet designed to catch every citizen with taxable income in a seamless, automated system.
The policy directly addresses public “concerns” that the new tax laws would require a Tax ID for basic activities like owning a bank account. The FIRS’s message is clear: that requirement is not new, but the mechanism for enforcing it—the irrevocable link between your NIN and your tax file—now is.

Why This Is a Revolution in State Power
This is more than bureaucratic tidying; it is the final step in creating a unified digital identity for every Nigerian that the state can use to track, trace, and tax. The NIN, originally conceived as a security and planning tool, has now been weaponized as the ultimate financial surveillance instrument.
The implications are vast:
For the informal economy: Millions of traders, artisans, and service providers operating in cash now have a digital tax shadow tied to their NIN, which is increasingly required for SIM cards, bank accounts, and travel.
For the wealthy and evasive: There is no longer a separate TIN to lose or forget; your identity is your tax file. Cross-referencing financial transactions with a single, lifelong number makes hiding income exponentially harder.
For every citizen: It creates a permanent, searchable financial profile for the state. Your NIN is no longer just who you are; it is a barcode for your economic life.
The FIRS urged the public to “ignore any misinformation,” framing the reform as an “efficiency and transparency” measure. But the subtext is undeniable: the government has built a digital panopticon. The walls between your identity, your bank account, and your tax obligations have been demolished. In the new Nigeria, you cannot hide from the state because the number that proves you exist is also the number that calculates what you owe.
