For this purpose, 120 corporations listed in TSE for the period 2008-2013 were studied. To calculate the transparency level, the Standard and Poor’s Index model was used by which transparency index in three areas of performance, owners and managers is studied. Simple and Multiple Logistic Regression models were applied to examine statistically. The results so achieved show that the statistical model is capable to identify the tax aggressiveness. The transparency in performance of the companies has no significant relationship with their financial policies. However, there is a positively significant relationship between the financial transparency as well as the transparency in the type and level of ownership with the tax policies of the company. Furthermore, the variable of the auditor’s opinion type, difference between declaration and diagnostic taxes and the company’s size has significant relationship with the company’s tax policies. %> http://taxjournal.ir/article-1-578-en.pdf %P 165-176 %& 165 %! %9 Research %L A-10-1-253 %+ %G eng %@ 2251-6484 %[ 2015
