Before the adoption of the amendment, the average tax rate on companies based on Article 131 was about 64%. Calculating method of companies’ income tax was received by virtue of article 131 of the act as follow: in the beginning 10% of company’s taxable income will be received, the rest of it will transfer to the direct tax article 131 table and up to 45% of taxable income will be computed, and also at the time of dividing the profits between shareholders, a double taxation will be deducted. Tax paying in the above mentioned way has led to inefficient economy and shareholders may reduce their liquidity (cash) and investments, so for solving this problem direct tax act has modified and many alternations had occurred on 2002/02/16; including applying a fixed rate equal to 25% and considering the appropriate dispensation but the main issue is monitoring the changes occurred in listed companies in stock exchange in Tehran caused by direct tax act modification in 2002 and the issues that change this flat rate for the companies. 2. Prior Research Now a days, tax as an important payable item by companies, become one of the most important financial issues which its amount is set in the context of tax law. In Iran, in accordance with the article 105 of the direct taxes law, legal entities are obliged to pay 25% of their taxable income to the government. In practice, however, because of some unacceptable costs from the tax viewpoint, effective tax rate is defined as cash ratio of fixed paid tax to the pre-tax income that is higher than the rate that is registered in law, it is clear that with an interval existence between taxable income and companies fixed payable taxes, effective tax rate will be higher. A large volume of literature in accounting and economy is considering real and effective rate of tax. This is the subject of Feldestein and Summers (1979), Fullerton (1984), Stickney and McGee (1982), Gupta and New berry (1997), Lammerson (2002), Plesko (2003), Gordon et al (2002), Lim and Hyun (2006), Dyreng et al (2007) COPY RIGHT © 2013 Institute of Interdisciplinary Business Research 523 ijcrb.webs.com MAY 2013 INTERDISCIPLINARY JOURNAL OF CONTEMPORARY RESEARCH IN BUSINESS VOL 5, NO 1 researches. These studies generally considered member of Organization for Economic Co-operation (OEC) and developed countries but the developing countries are less noted. In Iran, however, few research is settled on taxable profit, return on sale profit and fixed tax. These researches have taken place by Ghanbari Fard (1995), Ahadiyan (2000), Hasanpour (2001) and Safiri (2008). The mentioned findings shows some factors’ effect on the difference between fixed and return on sale profit, including different tax laws interpretation, differences between rules and regulations of principals adopted and accepted by accounting, payers tax evasion, exemption from taxation in legislation and government targets. This study tries to prepare an answer to this question, whether other external factor such as different interpretation of tax laws, differences between rules and regulations of principals adopted and accepted by accounting, payer’s tax evasion, exemption from taxation in legislation and taxation targets, internal factors like some financial variable such as size, profitability, financial leverage, amount of fixed assets and nonfinancial variables like ownership structure and industry type have any effect on the effective tax rate or not? 3. RESEARCH METHODOLOGY The present study have tested the research hypotheses by use of regression model and synthetic data (Baltaji, 2005). This study is describing variables’ state systematically and its nature is cross-correlation and considers the relation between variables by regression analysis presented by Rodrigrz and Hiemen (2010) in the below equation (1-1), (2-1) and (3-1). TAXi= (1) Where: TAX (Tax effective rate): total payable tax divided by total income before tax which is tax effective rate. SIZE (size): the sum of asset’s logarithm which is the company’s size index. PRO (return on sales): income before deduction of tax divided by total assets which would be profitable. LEV (leverage): total liabilities divided by total assets which is leverage. FIX (Fixed assets): total amount of fixed assets divided by total assets that are fixed assets amount. is i company model error in t year. TAXi= (2) Where: OWNit: I company ownership variable at the end of the year. TAXi= (3) Where: IDUit: I company’s industry variable at the end of t year (in this study the sample companies are classified in 9 industry). 5.Conclusion This research hypothesis results show that the size of a company, fixed assets, ownership type and industry will affect the amount of payable tax and increase or decrease the tax proportionally due to their amount (size). Automotive, pharmaceutical, chemical, machinery, cement, food, metal and tile industries par more tax than others and also companies that have more than 50% ownership of the stock are paying tax more than other companies. These results are achieved in a situation if the tax authorities and auditors acted according to the law and regulations, there will be no factor to affect the payable tax system and show growth or reduction. In this direction psychological factors and the auditors’ different interpretation about taxable income taxes should be taken to consideration. For instance a company that have more fixed assets is an agent which will affect the auditors and causes to receiving more taxes from the company.
