All taxpayers who, due to problems in the operation of the new IRMS system of the Tax Administration, cannot submit reports on calculated and paid taxes and contributions (IOPPD), forms and VAT returns from December, can do so until January 30, and if there are still problems in its functioning, the deadline will be further extended.
This was announced to "Vijesta" from the Tax Administration.
The Integrated Revenue Management System (IRMS) was supposed to launch on January 12th and enable the full digitalization of the Tax Administration's work and contacts with taxpayers. As of December 30th, the Tax Administration stopped accepting requests, cases and other documents in paper form.
According to tax laws, IOPPD forms and VAT returns for the previous month are submitted by the 15th day of the following month, i.e. for December they should have been submitted by January 15. Also, during this period, deadlines for various other documents issued by the Tax Administration expire, such as certificates of paid taxes that sports organizations needed to participate in the Ministry of Sports competition that ended today.
The Tax Administration told "Vijesti" that in a statement dated December 29, they announced the possibility of extending the deadlines "due to possible and announced difficulties in the stabilization period" of the IRMS.
"Considering the above, and due to objective technical circumstances, timely filed returns will be considered IOPPD reports and VAT returns for the accounting period December 2025 submitted by January 30, 2026. IRMS is working, with announced difficulties and adjustments. By the end of yesterday's working day, less than 72 hours from the moment of release into production, the number of submitted tax returns was four digits," the Tax Administration told "Vijesti".
They say that there are various reasons - challenges due to which a number of taxpayers cannot access or submit a request/application through IRMS.
"Every day, through communication with taxpayers, including through training organized with business and professional associations, these challenges are being resolved. Since these are announced, expected, and foreseen challenges that accompany such complex systems (the Tax Administration worked on several systems that were 10, 15, and 20 years old until the end of 2025), the Tax Administration monitors the dynamics on a daily basis and if an additional extension of the deadline is necessary, the public will be informed in a timely manner. Every taxpayer will be enabled to fulfill their legal obligation on time," the Tax Administration stated.
They state that certificates are also issued in paper form in urgent cases, and that the first ones were also issued via the portal.
On December 30, the Tax Administration announced that in the period from December 31, 2025 to January 12, 2026, their officials will "prepare with the contractor of this system for the transition to the production environment of the new system and the migration of data to it."
As previously announced by the Public Administration, IRMS is designed to be simple and intuitive for users, and with employee training, video instructions, a call center, targeted training for businesses and help desks in the largest offices, citizens will be provided with full support in using the system.
One of the important innovations of the system is the electronic registration and deregistration of employees, which should significantly reduce administrative procedures and the need for personal visits to the Tax Administration.
They also pointed out that better analytics would enable informed decision-making and fairer application of tax regulations, as well as provide better insight into economic trends and the ability to react more quickly to informal zones in the economy.
