The Nigeria Revenue Service (NRS) says its replacement of the defunct Federal Inland Revenue Service (FIRS) will overhaul the architecture of the country’s revenue administration.
The Executive Chairman of NRS, Dr Zacch Adedeji, said this in a television interview monitored from Abuja. The provision of the recently enacted tax reform laws changes the nomenclature of the country’s apex tax authority from FIRS to NRS.
According to Adedeji, NRS is not branding. It is a total institutional upgrade moving from fragmented revenue administration to a modern, digitalised, centralised and intelligence-driven system.
He said that under the new framework, multiple tax and revenue-related functions previously spread across agencies have been consolidated, with a stronger emphasis on data integration, automation, and reduced human discretion.
He dismissed allegations that the country’s newly enacted tax reform laws were altered after passage by the National Assembly.
“Only the officially gazetted Acts carry legal authority and are binding on taxpayers and administrators,” he said.
The NRS boss said that an Act of the National Assembly only became effective after presidential assent and official gazetting, with the gazetted version constituting the authoritative text in the event of disputes.
“Revenue agencies, courts, and taxpayers are therefore guided solely by the gazetted law, not draft bills, committee reports, or chamber debates.
“Neither the executive nor the revenue authority has any incentive or legal capacity to alter the law after passage,” he said.
Adedeji said that the overhaul of the NRS is also designed to support the Federal Government’s broader fiscal objectives. According to him, Nigeria’s tax-to-GDP ratio has improved in recent years, rising to about 13.5 per cent as at October 2025.
“But it remains below the African average and well short of levels seen in peer emerging markets,” he said. Adedeji said that the overall aim is on taxing profits and returns rather than capital or investment.”
