This research aims at the factors affecting tax revenues in Iran. To study the subject, first, a good model is selected according to the structure of Iran's economy and, then, a theoretical model as well as the corresponding variables and equations are presented. The study makes use of seemingly unrelated regressions method (SURE) and 3SLS because there are different and seemingly unrelated equations. The model is double estimated, once without virtual variables and again with virtual variables. This implies the existence of structural breaks in model equations. As a result of both estimates, it is shown that the change in the tax structure has had the least effect on import taxes as to increase tax revenues. Also, the changes in the tax structure have been the most effective in the other direct taxes and taxes on consumption and sale respectively so as to increase tax revenues.
