The increasing use of digital work requires better understanding of what affects the digital performance of individuals with respect to their IT identities. This study explores the impact of IT identity on digital performance in digital work. A review of the related literature has been conducted, leading to the development of a conceptual framework for investigating the relationship between IT identity and digital performance within the theoretical background of the identity theory. Such a model is developed, tested, and validated using structured equation modelling of the survey data in Australia. The study shows that rewards and digital experience have significant influence on IT identity. It finds that IT identity significantly influences both digital-enabled in-role performance and innovative performance. Furthermore, the study reveals that digital embeddedness and digital self-efficacy do not have significant impact on IT identity. This study has extended our understanding of the impact of IT identity on digital performance in the new “normal” working environment. It provides a validated framework for further exploring the use of digital work in organizations.
