From January 1, 2026, Nigeria has moved to a simplified business identifier system. Your Corporate Affairs Commission (CAC) RC Number now automatically serves as your Tax Identification Number (TIN). However, you still need to ‘activate’ and link this number with your bank to ensure your account remains fully operational and compliant with CBN and NRS regulations.
The 2026 Linking Process
- Automated Validation: Most banks now use the NRS API to pull your tax data directly. You simply provide your RC Number, and the bank validates it as your TIN.
- Manual Update: For older accounts, visit your bank’s ‘Corporate Desk’ or use their mobile business app to upload your post-incorporation documents.
- Verification: You can verify your status on the NRS Tax ID Portal before visiting the bank.
Failure to link your TIN can lead to account freezes or restrictions on foreign exchange. For more on why this is mandatory, see TCC for Business Loans. For official banking guidelines, check the CBN website or Kuda Business for digital-first updates.
