In the quantitative stage, the population is consisted of the whole tax payers of Iranian National Tax Administration which the number of them is unlimited. In order to collect data, two questionnaires were used. In the quantitative stage, the core identified in the qualitative stage is obtained using explanatory-factor analysis method, path analysis, variables and constructs and the relevant questions (items) for measuring the variables and after examining the reliability and validity ( content, formal and construct validities) the final scale is measured through explanatory-factor analysis and confirmation of model validation. Also in the model evaluating performance of tax system, the relations are determined through the method of structural equation modeling. Finally, from the findings, 4 main categories were identified and 70 sub-categories were extracted for all the categories of ethical infrastructure of tax system, ethical infrastructure of generating tax system, ethical, cultural and social infrastructure of tax system and ethical infrastructure of tax law and regulations
