The implementation of the project “Advancement of the main systems of the National Revenue Agency for the provision of data and services to internal and external systems” will build on the main information systems in the National Revenue Agency providing electronic services, as well as the register of obligations and the register of obligated persons in the NRA, and will allow for the exchange of registration and transactional data electronically in the form of internal administrative electronic services. The information will be accessible to natural and legal persons, who will be able to receive information about the submitted documents and their obligations to the NRA in real time after successful electronic identification, as well as the possibility to pay online.The project will create the necessary prerequisites for easier exchange of information, both between the internal systems of the National Revenue Agency and with systems at national and cross-border level, which will lead to improved quality and speedy action in the provision of administrative services to natural and legal persons by the Agency.
