Cameroon Tax System: What Is A Single Identification Number

Single identification number

Every registered business in Cameroon has a unique number that is used to identify the it as a taxpayer. This taxpayer’s identification number, known as the single identification number, is attributed to the business owners immediately they start the registration procedure of their business.

Any natural or legal person starting a business in Cameroon is attributed a single identification number by the Directorate General of Taxation. The number is attributed on a permanent basis upon effective localization of the taxpayer. The number is attributed only after the taxpayer must have filed an application to register the business with the competent tax authority within 15 (fifteen) working days after commencement of activities.

    Greetings. You have a womderful blog here. I want to ask a question, what taxes do a landlord pay? I know about lamd tax and tax on the contrat de bail. But is that all? What documents can a landlord show to Proff that he pays taxes, is the attestation of non redevance a deal with landords?

      Good morning
      The land Lord pays the rental income tax if he has tenants. It is calculated on the annual amount of rents collected. He also pays the Advanced tax on rents ( PSL) though it is usually paid by tenant at the time of registration of the rent contract. This is usually deducted when declaring your income tax at the end of the year.
      Thanks for reading.
