Therefore, the evolution of the tax system is necessary to improve its status in terms of its functions and to achieve the objectives set forth in the Sixth plan, in particular its quantitative objectives. The present study first examines the current state of the tax system within the framework of tax indices and explains the objectives of the Sixth plan for each of these indices and then, considering the major challenges of the tax system, plans to create changes in the country's tax system. The purpose of this study is to evaluate the tax system of the country on the one hand, and on the other hand, to rank the selected tax system. To identify the tax system by experts, the principal components identified by the 10 experts were assessed using the Delphi approach and finally by the 31 components that were probable in the tax system. Then the identified components were evaluated by DANP method and the inefficiency of the legal system was introduced as the most important component. Also, Vikor's results showed that the first rank Alborz Province Tax organization, then Tehran Province Tax belonges to Organization and the third rank belonged to Kermanshah Tax Organization.
