Tax Information Systems

ADIS comprises over 48 application areas covering all types of taxes, from income to real estate. The system manages key agendas for the General Financial Directorate and is essential for the operation of the tax administration in the Czech Republic.

ADIS also ensures communication with other public administration systems, such as the Real Estate Cadastre, the Insolvency Register, and the Population Register. It collaborates with other authorities for data exchange, including the Ministry of Labour and Social Affairs and the Czech National Bank.

ADIS is maintained long-term and gradually modernized to comply with current legislative requirements and ensure stable operations that better align with contemporary tax administration standards, enabling more efficient work for tax authority employees. The goal is also to improve user experience and reduce administrative burden.

As part of our strategy, we have established a specialized division that integrates expert teams from the acquired companies GIST and TaxLabs. By doing so, we are pooling proven know-how and building upon previous successful projects. We leverage the expertise of professionals who contributed to the development of the ADIS system in the past, enabling us to continue its advancement with deep knowledge of both the environment and specific requirements. Our goal is the incremental modernization of the system while ensuring full operational continuity. Simultaneously, we are automating key processes, strengthening security, and ensuring compliance with legislative requirements, including the NIS2 Directive and GDPR.
