Purpose – This study aims to examine the effect of the structure of board of directors and company ownership on social responsibility disclosure of listed companies on the Tehran Stock Exchange. Design/methodology/approach – The variables of the study included independent board of directors, institutional ownership, managerial ownership, family ownership and family-managerial ownership. The study population consisted of 125 listed companies on the Tehran Stock Exchange during the years 2009- 2014. Content analysis used to measure social responsibility disclosure level and test hypothesis was performed using multiple regression analysis. Findings – The results demonstrated that there was no significant relationship between any of the independent variables and the level of social responsibility disclosure. This study empirically shows managers, investors and other stakeholders that if business owners are made of different groups, namely, institutional ownership, managerial and family ownership, it will not affect the social responsibility disclosure in annual reports. Originality/value – The outcomes of the current study may bridge the gap between social responsibility disclosure and ownership structure in a developing country like Iran.
