IOTA was established in 1996 in the 3rd Conference of Central and Eastern European and Baltic Countries' Tax Administrations held in Warsaw (28-30 October).
IOTA in the initial years successfully concentrated on profile building and establishing credibility on the international scene. A common understanding was also reached that IOTA represented the members' mutual interest by providing a forum for the exchange of experience and assistance for the modernization of tax administrations in Central and Eastern Europe, especially in the context of the enlargement of the European Union. By the joining of the EU of several member states the profile of IOTA has shifted from assistance in modernization to share of experiences and best practices.
