The CFE participates in the work of the OECD (Organisation for Economic Co-operation and Development) and takes part on a regular basis in the corresponding meetings and workshops. By means of workshops, the OECD intends to collect information on regulations concerning the professional law in force in the individual countries in order to tackle deregulation which is to be as far-reaching as possible. Here, the CFE has to make clear that certain professional regulations have to be maintained in order to protect both the taxpayer and the Revenue authorities.
Furthermore the CFE cooperates with AOTCA  (Asia-Oceania Tax Consultants Association). AOTCA is the International Organisation for the tax professionals in that region. The main purpose is to exchange information, knowledge and experiences on taxation and to exert for expansion and development of tax profession. Through regular meetings CFE and AOTCA are staying in close contact.
In 2007 CFE has obtained the consultative status with the ECOSOC  (Economic and Social Council of the UN). As such, the CFE is able to attend meetings of the above Committee of Experts on International Cooperation in Tax Matters .
