TIN Registration in Guinea — Complete Guide
The NIF (Numéro d'Identification Fiscale) is issued by the Direction Nationale des Impôts (DNI) in Guinea. Registration is free and typically takes 3-7 business days. Registration is currently available in person at DNI offices. The TIN is governed by the Code Général des Impôts de Guinée and administered by the Ministère du Budget.
All businesses operating in Guinea and individuals in formal employment are required to register for a NIF. The NIF is a Variable numeric identifier needed for tax filing, business bank accounts, government contracts, and customs clearance. Failure to register carries penalties: fines apply.
