CALABAR –The Cross River State Internal Revenue Service (CRIRS) has sensitised residents, businesses, Ministries, Departments and Agencies (MDAs), as well as other organisations on the implementation of the new Taxpayer Identification (Tax ID) system introduced by the Nigeria Revenue Service (NRS) in collaboration with the Joint Revenue Board (JRB).
According to a public notice shared by the revenue authorities, the new 13-digit Tax ID is designed to serve as a single, unified identity for taxpayers across Nigeria, replacing the existing Tax Identification Number (TIN) validation system.
The initiative, implemented in line with Sections 6, 7 and 8 of the Nigeria Tax Administration Act, 2025, aims to strengthen tax administration, improve transparency, enhance service delivery, and harmonise taxpayer records across federal and sub-national levels.
Revenue authorities stated that the new Tax ID system is expected to simplify tax compliance processes, including registration, filing and payment, while also reducing tax leakages and improving accountability in revenue collection.
As part of the transition, organisations currently utilising the old TIN validation API have been advised to migrate to the new Tax ID validation framework.
The notice further directed organisations seeking integration or validation services for individuals, enterprises and business names to contact the Standardisation and Modernisation Department of the Joint Revenue Board, while corporate entities requiring related services should liaise with the Tax Automation Department of the Nigeria Revenue Service.
The Cross River State Internal Revenue Service urged taxpayers and stakeholders to familiarise themselves with the new system as authorities intensify efforts towards a more efficient and digitally driven tax administration process nationwide.
