The architecture of information systems of the State Revenue Committee of the Ministry of Finance of the Republic of Kazakhstan includes five main systems:
* Integrated Tax Administration System (ISNA);
* KEDEN;
* Smart Data Finance (SDF);
* Risk Management System (RMS);
* An electronic system for receiving and processing electronic invoices (ESF).
These systems provide automation of tax and customs administration processes, covering the full life cycle of a taxpayer — from registration to termination of operations. The systems have functions for calculating and accounting taxes, maintaining personal accounts, receiving and processing reports, conducting control measures, risk management, and providing public services in electronic format.
