The Tax Identification Number (Tax ID) is a unique 13 digit system-generated number assigned to all taxable persons and businesses in Nigeria for the purpose of tax administration, by the Nigerian tax authorities (Nigeria Revenue Service or State Boards of Internal Revenue) to track and manage their tax obligations and compliance history. It serves as a taxpayer’s financial identity within the national tax system. 

Key Features of TIN

• A Unique Identity: Each taxpayer has a distinct number used for all interactions with tax authorities.
• Integration:
  • For individuals, their National Identification Number (NIN) automatically functions as their TIN.

Why TIN is Mandatory?
