In India's banking industry, where public sector banks (PSBs) contribute greatly to the country's socio-economic growth, corporate social responsibility (CSR) has become an important aspect of holding organizations accountable. Examining how well-known PSBs in Karnataka follow national and international reporting standards and if they comply with the requirements of the Companies Act, 2013, this study finds out how much, how well, and how transparently these PSBs report on corporate social responsibility. The research examines a variety of sources, including annual reports, sustainability disclosures, statistics on CSR expenditures, and evidence from individual projects, in order to draw conclusions. Full transparency, involvement of stakeholders, patterns of funding distribution, geographic reach, priority of themes, and reporting of results are all parts of the assessment framework. The results show that although the majority of PSBs comply with CSR expenditures to a high degree, there are substantial differences in the thoroughness and openness of reporting. Disclosures frequently fail to provide clarity on project monitoring, long-term sustainability, community satisfaction, and financial outlays, while qualitative impact assessments frequently take a back seat. Education, rural development, health, and financial inclusion are the primary areas of concentration for CSR projects in Karnataka, however there is still a lack of consistency in how these programs analyze their impact. In addition to revealing problems with alignment with the SDGs, the research reveals a lack of procedures for stakeholder feedback and third-party review. In order to strengthen accountability and public confidence, the study stresses the importance of standardized CSR reporting frameworks, transparency measures, and disclosures focused on outcomes. Some of the suggestions include incorporating community-centric assessment tools, enhancing corporate governance processes, and using sustainability reporting frameworks like GRI or BRSR. Policymakers, regulators, and financial institutions in India may use the research's insights to make CSR more effective and transparent. It also adds to the larger conversation on CSR governance in the banking industry.
