“25 Days to Go”: FIRS Begins Final Countdown to Historic Tax Overhaul and NRS Transition

ABUJA — The Federal Inland Revenue Service (FIRS) has officially started the clock on the nation’s most significant fiscal shift in decades. In a public alert issued via its official X (formerly Twitter) handle, the agency warned taxpayers that only 25 days remain until the new tax laws take full effect on January 1, 2026.

With the deadline fast approaching, the tax authority is urging all citizens, corporate bodies, and multinationals to use this brief window to familiarize themselves with the updated legislation to avoid compliance pitfalls in the new year.

From FIRS to NRS: A New Identity

Central to this transition is the rebranding of the regulator itself. Come January 1st, the FIRS will cease to exist by that name, emerging instead as the Nigeria Revenue Service (NRS).

This is not merely a cosmetic change. The Nigeria Revenue Service (Establishment) Act expands the agency’s mandate beyond traditional tax collection, positioning it as the sole, unified authority for all federal revenue. The goal is simple: improved efficiency, strict accountability, and a decisive end to the era of multiple agencies collecting government revenue in silos.

The “4% Development Levy”: Consolidation, Not Duplication

One of the most discussed aspects of the reform is the introduction of the 4% Development Levy. The FIRS has moved to clarify that this is not a new tax added to existing burdens, but rather a “streamlining” measure.

Previously, businesses navigated a chaotic web of separate charges, including the Tertiary Education Tax, NITDA levy, and other special-purpose fees. The new law consolidates these into a single structure. This includes a harmonized levy on assessable profits and specific provisions for imported goods. The agency argues that this consolidation will drastically reduce the compliance burden, offering businesses a predictable fiscal environment rather than a barrage of surprise levies.

Global Alignment for Multinationals

The countdown is particularly critical for multinational enterprises operating in Nigeria. The new laws introduce a minimum Effective Tax Rate (ETR), a move designed to align Nigeria with global best practices and prevent base erosion.

Additionally, the reforms modernize the Capital Gains Tax framework. In a bid to balance revenue generation with investment incentives, the law offers relief for reinvestments and stronger protections for small investors, ensuring that the tax net widens without strangling economic growth.

With the January 1 deadline set in stone, the window for preparation is closing. Businesses are advised to review their tax positions immediately.
