1. Objectives and Scope of the Initiative
The Integrated Revenue Management System (IRMS) represents a major reform milestone of the Tax Administration of Montenegro, aimed at achieving the full digitalization of tax services, strengthening trust between the state and the business sector, combating the grey economy, and fulfilling obligations arising from the European integration process of Montenegro. The scope of IRMS extends beyond a conventional IT upgrade. It constitutes a systemic transformation of institutional operations, data management, service delivery, and communication with taxpayers. The reform addresses long-standing structural challenges in tax administration by establishing a unified digital framework that supports efficiency, transparency, and a partnership-based relationship with citizens and businesses.
2. Technical Methodology and Operational Approach
IRMS was developed as a single, centralized, and modern IT platform integrating all core tax data, processes, and communication channels. The system is operationalized through the IRMS Portal, which serves as the primary digital access point for all taxpayer services.
Key methodological principles included:
- Centralization of data and workflows within one integrated system;
- End-to-end digitalization of tax processes;
- Interoperability with other public institutions and funds;
- Introduction of advanced analytics for tax risk assessment and compliance monitoring.
The system enables a shift from reactive control mechanisms to proactive, data-driven management of tax obligations.
Core functionalities and innovations
Services for Citizens and Businesses – IRMS delivers a fully digital service environment, including:
- Digital registration of legal entities and individuals;
- Electronic registration and deregistration of employees within minutes;
- Secure electronic mailbox for official decisions, notifications, and correspondence;
- Electronic submission of all tax returns (VAT, payroll taxes, and others);
- Electronic tax payment functionality;
- Elimination of the need for in-person visits to tax offices.
These functionalities significantly reduce administrative costs, time loss, and procedural complexity, particularly benefiting micro, small, and medium-sized enterprises, as well as seasonal employers.
System-Level Improvements – at the institutional level, IRMS enables:
- Consolidation of all tax-relevant data into a single system;
- Advanced analytics and improved tax risk management;
- More effective detection and suppression of the grey economy;
- Enhanced coordination and data exchange with other public bodies.
3. Key Challenges and Solutions Adopted
One of the primary challenges was managing the transition period for taxpayers and professional intermediaries. To address this, the reform adopted an inclusive and partnership-based approach, emphasizing:
- Cooperation between the Tax Administration, the business community, and the accounting profession;
- Recognition of transitional constraints and behavioral change requirements;
- Special consideration for micro and semi-formal businesses.
The reform explicitly positioned digitalization as a facilitative tool, supporting the transition from informal to formal economic activity rather than acting as a barrier.
Acknowledging that technology alone does not guarantee reform success, the Tax Administration implemented a comprehensive support framework, including:
- Video tutorials covering key system functionalities;
- A dedicated call center for citizens and businesses;
- Help desks in major tax offices;
- Targeted training sessions in cooperation with business associations;
- Continuous professional development for Tax Administration staff.
Education and capacity building were defined as critical success factors, equal in importance to the technical solution itself.
4. Impacts and Measurable Results
The implementation of IRMS has generated multiple positive outcomes, including:
- Reduced administrative costs and processing time;
- Increased collection of public revenues;
- More equitable and consistent application of tax regulations;
- Improved control of informal economic activity;
- Strengthened trust between the state and taxpayers.
Initial fiscal indicators show a measurable increase in revenue collection compared to the previous year, confirming the system’s effectiveness.
European and International Implications – IRMS holds strategic importance in two dimensions:
- Fulfillment of obligations within Montenegro’s European integration process, particularly under Chapter 16 – Taxation;
- Enhancement of national competitiveness within the EU’s digital single market framework.
The system is aligned with European standards and best practices, reinforcing institutional readiness for integration into a fully digitalized European administrative environment.
Broader implications and transferability – IRMS demonstrates a shift in public administration paradigms:
- From bureaucratic to digital;
- From reactive to proactive;
- From control-oriented to partnership-based;
- From fragmentation to integration.
Its comprehensive design, clear strategic vision, and strong stakeholder cooperation make IRMS a transferable model of good practice, relevant for other countries undertaking public administration and tax system reforms.
