The International Fiscal Association (IFA) was founded in 1938. IFA’s objective is the study and advancement of international and comparative law in regard to public finance, specifically international and comparative fiscal law and the financial and economic aspects of taxation.
IFA is the only non-governmental and non-sectoral international organisation dealing with fiscal matters. IFA is a unique neutral and independent platform where representatives of all professions and interests can meet and discuss international tax issues at the highest level.
IFA's achievements are attributable to high-level representatives from both the private and public sectors, including the Courts, Universities, the judiciary, government officials, academia, and international governmental and non-governmental organisations, who are actively involved and contribute worldwide with their knowledge and efforts to the research, publications, congresses, and seminars organised by IFA, its Branches, and Regions.
IFA has maintained high standards and quality in its debates and research over the years. In this way, IFA offers the necessary independent and neutral platform to experts belonging to different sectors of society, where opinions on topics of international taxation can be exchanged with respect for each other's background and responsibilities.
