Corporate Social Responsibility (CSR) has emerged as a critical mechanism for aligning business practices with societal needs & particularly in developing economies like India. The enactment of Section 135 of the Companies Act, 2013 & marked a transformative shift by making India the first country to legally mandate CSR activities for eligible companies. This paper critically examines the legal architecture governing CSR in India & evaluates its effectiveness in addressing the socio-economic challenges faced by underprivileged communities. Through doctrinal analysis & empirical review of CSR expenditure data & the study investigates whether the legislative mandate has translated into meaningful social impact & especially in sectors like education, healthcare, rural development, & economic empowerment. It explores the nature of CSR implementation & identifies gaps in governance & accountability, & assesses the extent to which CSR projects have been inclusive & sustainable. The paper also analyzes the regional & sectoral disparities in CSR fund allocation & identifies systemic challenges, such as inadequate community participation & urban-centric project concentration. By drawing comparative insights from CSR frameworks in other emerging economies & the paper suggests policy reforms aimed at improving transparency, inclusiveness, & long-term community development. The findings underscore the potential of India’s CSR legislation to serve as a replicable model for other developing nations & while also highlighting the need for more robust oversight & community-driven approaches to maximize impact.
