Since assuming leadership of the Federal Inland Revenue Service in September 2023, Dr. Zacch Adedeji has spearheaded a significant transformation of Nigeria's revenue administration. The revenue numbers provide a clear timeline of this transformation, with tax collections rising dramatically. In 2023, tax collections were approximately N12.3 trillion, increasing to about N21 trillion in 2024, and then reaching N28.3 trillion in 2025, surpassing the year's target of N25.2 trillion.
The momentum has continued into 2026, with the Nigeria Revenue Service generating N21.6 trillion in the first six months of the year, compared to N14.27 trillion in the corresponding period of 2025, representing a 49 percent increase. These figures indicate a broader shift toward stronger domestic revenue mobilization and reduced dependence on volatile revenue sources. The growth in revenue has come alongside a fundamental change in how taxes are administered, with technology being placed at the heart of the revenue system.
Adedeji's tenure has seen the introduction of Rev360, a platform designed to give taxpayers a more integrated digital experience across key services and interactions with the revenue authority. This is part of a wider digital strategy aimed at simplifying compliance, improving data visibility, and reducing the friction that has historically characterized interactions between taxpayers and tax authorities. The move towards electronic invoicing and digital fiscal systems has also created greater visibility over transactions, strengthened the revenue authority's ability to verify declarations, and reduced opportunities for under-reporting.
The policy reforms have provided the legal foundation for this transformation, with new tax laws taking effect in January 2026. The Nigeria Tax Act, Nigeria Tax Administration Act, Nigeria Revenue Service Establishment Act, and Joint Revenue Board of Nigeria Establishment Act collectively represent a major restructuring of the country's tax architecture. The reforms aim to simplify compliance, clarify responsibilities, and reduce duplication, addressing long-standing concerns around overlapping taxes and multiple demands on businesses.
The institutional shift is captured in the transition from FIRS to NRS, reflecting a broader approach to revenue mobilization and administration, with a stronger emphasis on collaboration, data, and integration. Revenue collection increasingly requires agencies to work together rather than operate in silos, as seen in the National Single Window, which brings relevant agencies involved in trade processes into a more coordinated digital environment.
Improvements in staff allowances and welfare have also been an important part of the transformation, as a high-performing revenue service requires a motivated and properly equipped workforce. The infusion of young professionals into the Service has brought fresh energy, digital skills, and new ideas, strengthening the NRS's capacity to deliver on its expanding mandate. A better-supported workforce, combined with new talent and technology, is ultimately reflected in the Service's growing efficiency, stronger revenue performance, and ability to engage taxpayers in a more modern and responsive way.
The transformation is also symbolized by the completion of the NRS headquarters, a project that had remained unfinished for over 20 years. In April 2026, President Bola Ahmed Tinubu commissioned the 16-storey NRS headquarters, a modern facility designed to accommodate about 3,000 staff and equipped with a data processing centre, training facilities, an auditorium, a clinic, a library, and a gym. The significance of these achievements becomes clearer when viewed together, as the story is not just about a revenue authority collecting more money, but about an institution being rebuilt around technology, stronger laws, better coordination, improved infrastructure, and a more modern understanding of the taxpayer.
