Federal Inland Revenue Service (FIRS) has revised its Standard Operating Procedure (SOP) as part of efforts to improve consistency, transparency, and service delivery in tax administration across the country.
According to a statement on Monday in Abuja by Mr. Collins Omokaro, Special Adviser on Communication Strategy and Advocacy to the Executive Chairman of FIRS, the revised SOP offers a unified framework for core tax processes including registration, payment, audit, and enforcement.
“This is about people, experience, and impact. It’s a step toward a tax system that supports voluntary compliance and national development,” Omokaro said.
He explained that while FIRS field offices have long operated with good intentions, inconsistent methods across different locations often created confusion for taxpayers.
The revised SOP, he said, is designed to eliminate such disparities by providing a single, clear roadmap for operations in all of the Service’s over 300 offices nationwide.
More than just a procedural manual, the new SOP is described as a statement of institutional direction, reflecting values that define the future of the Service.
Omokaro quoted Dr. Zacch Adedeji, executive chairman of FIRS, as saying that “This SOP is not just a technical document—it is a declaration of who we are becoming as a service. It reflects our commitment to transparency and service to the Nigerian people.”
The SOP update is one component of a broader reform agenda underway at FIRS, which aims to transform the agency into a fully service-oriented institution.
The changes are also aligned with the ongoing digital transformation within the agency, which is intended to harmonize human and technological systems for faster, more reliable, and taxpayer-friendly service delivery.
Internally, the SOP is expected to enhance operational efficiency and provide a foundation for improved staff training, clearer guidance, and stronger evaluation systems. Omokaro noted that every FIRS employee is expected to study, implement, and embody the procedures outlined in the new document.
“With this rollout, every FIRS staff member has a clear mandate: study it, apply it, and embody it. That’s how we’ll earn the trust of Nigerians,” he said.
The SOP reform is being introduced as part of the Service’s broader mission to reposition itself as a modern tax authority grounded in accountability, consistency, and a shared sense of national purpose.
The move comes as the FIRS continues to modernize its processes, improve tax collection efficiency, and foster a culture of voluntary compliance—all aimed at strengthening revenue mobilization to support Nigeria’s development agenda.
