Automated tax information system

ADIS creates application-technical support of Tax Administration of Czech Republic. This is the application for the whole republic with uniform technical infrastructure.

ADIS system consists of partial engines used for tax administration operations – tax subject register, processing of tax statements (tax returns, tax reports or tax offsets) for individual taxes, common sectional activity engines necessary for tax administration, accounting, collection and exaction, transfer of financial resources to entitled recipients and modules of necessary system support.

Czech Tax Administration website includes the MOJE daně portal application built into the framework of ADIS system (Online revenue authority (tax information mailbox), Electronic submissions for Financial Administration, Registration of sales...), which is the service for tax subjects.


ADIS communicates with other systems

ADIS system takes over data eg. from real estate register, insolvence register, citizen register, motor car register. Data exchange with ČNB, that administrates accounts of all revenue authorities, is necessary as well. ADIS system provides information also for the system of national social support operated by MPSV which are used to evaluate justified claims for social benefits for individuals. ADIS system provides international information exchange in the tax administration area too.

ADIS system is constantly been developed, updated and customized according requirements from information policy of General Financial Directorate, legislation (including EU legislation – ADIS system connection with EU) and not least its users.
