The transition from Indian GAAP to Ind-AS for aligning Indian financial reporting with International Financial Reporting Standards (IFRS) marked a paradigm shift in financial reporting in India. This transition was a significantly impacted on performance of Indian Companies. Therefore, the study is undertaken to know the impact of Ind-AS on the profitability of information technology companies. The study period covered a total of sixteen years from 2008-09 to 2023-24; further, it was divided into two regimes, eight years each of pre-adoption (2008-09 to 2015-16) and post-adoption (2016-17 to 2023-24). The study considers Net Profit Ratio (NPR), Return on Assets (ROA), Return on Equity (ROE), Return on Capital Employed (ROCE), and Earnings per Share (EPS) as measures of profitability. We used a Shapiro-Wilk test to check the normality in a data set, and further, the paired t-test (parametric) and Wilcoxon rank test (non-parametric) have been used based on normality distribution. The results indicate that the profitability position of the majority of companies was better in the pre-adoption period of Ind-AS; a decline in almost every profitability ratio is notable in the post-adoption period of Ind-AS. Further, the study also found that changes in accounting areas such as depreciation & amortization, fair valuation of derivative & financial instruments, revenue recognition, and reclassification of actuarial gains/losses may impact on profitability.
