CSR has been an emergent area of research in the recent past. Most of the scholars, academicians and practitioners have made massive contributions in this field. The reason why IT sector is chosen is because it is uniquely positioned in terms of skills, expertise and facilities that can help benefit society in the long run. The companies that have been chosen are Infosys and Wipro as these are the top two companies that have satisfied the legal requirements in the context of CSR and have stayed profitable throughout. The main purpose of this study is to understand the history, concept and background of CSR in India, analyse the CSR expenditure for the post-mandate period of Infosys and Wipro and analyse the relationship between CSR and firm performance (net profit, operating margin, ROA, ROE and market capitalisation) separately for Infosys and Wipro. Lastly, the motive is to analyse the major CSR domains of the selected two companies and comment on the similarities and differences altogether. The sources of data used in this study are secondary and empirical in nature including annual reports of the selected two companies namely; Infosys and Wipro majorly for the post-mandate period (2014-19). The CSR expenditure and the profitability ratios including return on assets and return on equity has been considered based on the review of literature of CSR and firm performance. A CSR index has been created consisting of ten parameters explained in detail in the findings and analysis section. SPSS (statistical package for social sciences) 23 has been used to analyse the correlation and linear regression between the independent variable (CSR index scores) and profitability measures (net profit, operating margin, ROA, ROE and market capitalisation) separately. The findings suggest that in terms of CSR expenditure Infosys contributed more than 2% towards CSR during the financial years 2016-17, 2017-18 and 2018-19 and Wipro has even gone beyond 2% in the financial years 2015-16, 2016-17, 2017-18 and 2018-19. In terms of CSR and firm performance, it can be observed that there is a negative or weak correlation and no linear relationship between the scores of CSR index and the profitability measures with respect to Infosys and Wipro as well. In terms of CSR domains, as compared to Infosys, the CSR domains that can be added to the Wipro’s CSR activities can be rehabilitation of homeless and orphans and disaster management relief. The domains that can be added in the context of both the companies can be gender equality programs, women safety and dignity, enhancement of vocational skills for women and care and support for the elderly. Women can be focused more upon in terms of safety provision now-a-days.
