How to register for tax with FIRS-Federal Inland Revenue Service

  • Post category:Business / Tax

After the Corporate Affairs Commission (CAC) issues a certificate of incorporation or business name to Business AYX, what next? This question is one of the pressing issues from new business owners in Nigeria. A new corporation may need to register with different regulatory agencies, depending on the type of industry. As paying taxes is one of the civic duties in Nigeria, a taxable person must also register for taxes in Nigeria. The two regulatory bodies responsible for taxes in Nigeria are the Federal Inland Revenue Service (FIRS) as well as the relevant State Internal Revenue Service (IRS). Registration with FIRS will not relinquish an organization from the tax obligations with the State IRS. A taxable person, therefore, needs to register separately with both bodies. It also means that Business AYX will register for tax with FIRS and the State tax authority.
