Stakeholders' conscious follow-up on companies' operation pressured business organizations to be responsible for the society and environment. Companies social and environmental reporting is essential to ease this pressure. Despite its importance, there is no clear consensus on the motivation of companies for their reporting. Therefore, the aim of this study was to examine the motivational factors influencing social and environmental reporting from large tax payers in Ethiopia. An explanatory research design through quantitative research approach was employed by using both primary and secondary data source which was collected from 262 sampled firms in 2018. The regression result revealed that firm age, size, profitability, board size and industry sensitivity had a positive and significant influence on social and environmental reporting, whereas, leverage had a negative and significant impact on social and environmental reporting. This result implied that beyond the voluntary nature of Ethiopian companies' social and environmental reporting, they have been using their reporting to legitimize their position in the society.
