VUCA and the complexity of global competition urge all organizations to be ready for change including public sector organizations. This study aims to investigate the influence of involved communication and perceived organizational support on readiness for change in the public sector. The study also explores the mediating role of organizational identification. Data from 437 respondents working at the National Tax Authority were collected through an online survey and 384 respondents data were further analyzed. This research contributes to predictors that affect readiness for change in the public sector in Indonesia. Hypothesis testing was conducted using Structural Equation Modeling with Lisrel 8.8. The results show a significant positive effect of involved communication on readiness for change, while perceived organizational support has a nonsignificant effect on readiness for change. Organizational identification partially mediates the relationship between involved communication and readiness for change, and fully mediated perceived organizational support and readiness for change. This study contributes to the field of human resource management through practical guidelines to enhance readiness for change in facing organizational changes in the public sector especially in taxation service.
