This study aims to analyze the effect of Islamic Social Reporting (ISR) and the Maqashid Shariah Index (MSI) on the financial performance of Islamic Commercial Banks in Indonesia, both partially and simultaneously. Financial performance is proxied by Return on Assets (ROA). This study employs a quantitative approach with a causal-associative design. The population consists of all Islamic Commercial Banks registered with the Financial Services Authority (OJK) during 2022–2024. Using a purposive sampling technique, 11 banks were selected as the sample, resulting in 33 panel data observations (cross section and time series). Data were analyzed using panel data regression with the Random Effect Model (REM) selected as the best estimation model, processed using Eviews 14. The results indicate that ISR has a positive but insignificant effect on ROA (coefficient 0.110666; probability 0.3832 > 0.05), MSI also has a positive but insignificant effect on ROA (coefficient 0.318965; probability 0.2215 > 0.05), and simultaneously ISR and MSI do not significantly affect ROA (F-statistic 1.728061; probability 0.194843 > 0.05), with an Adjusted R-squared of only 4.35%. These findings indicate that the financial performance of Islamic Commercial Banks in Indonesia is more influenced by conventional financial factors than by the dimensions of sharia social disclosure and the attainment of maqashid shariah alone.
