On 25 September 2026, the Croatian Tax Administration (Porezna uprava) issued a formal notice informing all fiscalization system users that the FiskAplikacija platform will be temporarily unavailable on Saturday, 26 September 2026, due to planned maintenance works on the information system infrastructure. This announcement is critical for all taxpayers, software developers, and fiscalization intermediaries who rely on the continuous operation of the e-invoicing and fiscalization ecosystem mandated under the Fiscalization Act. The maintenance window is intended to deploy system upgrades, security patches, and performance enhancements to ensure the reliability of the Fiscalization 2.0 framework, which governs real-time invoice reporting and fiscal receipt issuance for B2C and B2B transactions. Taxpayers are advised to schedule their fiscalization operations accordingly and avoid any time-critical submissions during the announced downtime period.
Key Takeaways
- Planned System Downtime: FiskAplikacija will be completely inaccessible on 26 September 2026, affecting all fiscalization services including eRačun issuance, receipt verification, and intermediary communications. Taxpayers must complete any urgent fiscalization tasks before the maintenance window begins.
- Fiscalization 2.0 Infrastructure Upgrade: The maintenance is part of the ongoing modernization of the Fiscalization 2.0 platform, which introduced mandatory e-invoicing and real-time data exchange. These upgrades aim to improve system stability, reduce latency, and support higher transaction volumes as Croatia expands its digital tax compliance framework.
- Compliance Planning Required: Businesses using cash registers, ERP-integrated fiscal solutions, or the MIKROeRAČUN application must adjust their end-of-day fiscalization routines for 26 September. Failure to fiscalize transactions on time due to known downtime does not exempt taxpayers from legal obligations; alternative procedures may apply per Tax Administration guidance.
