Croatia Introduces New Fiscalization Service Adjustments for 2026

Starting January 1, 2026, Croatia will implement updates to its Fiscalization Act for B2C transactions, supported by a revised fiscalization service available for testing by November 2025. The new service will add optional buyer OIB submission, a method for correcting receipt data, stricter compliance controls, and functionality for reporting business hours.

Starting January 1, 2026, new provisions of the Fiscalization Act concerning end-consumer (B2C) transactions will come into effect in Croatia. To support this transition, an updated version of the fiscalization service, reflecting the upcoming legal changes, will be made available for adaptation and testing by early November 2025.

The updated service will introduce several changes:

• Option to submit the buyer’s OIB (personal identification number) during receipt fiscalization, expanding all relevant service methods with an additional data element.
• New method for receipt data changes, enabling corrections to payment methods and the buyer’s OIB.
• Stricter controls during the fiscalization process to ensure compliance and accuracy.
• There is new functionality for reporting business hours, allowing companies to register, retrieve, and delete working hours on business premises directly through the service.

The current technical documentation is already available under the Fiscalisation for End-Consumer Transactions / Technical Data section of the official portal- Technical data.

Updates and additions to the documentation may follow as the implementation progresses.
