EET 2.0 nabírá na tempu, je dostupná technická dokumentace i první milníky

The Financial Administration has published the basic technical documentation for the EET 2.0 system, intended primarily for developers and suppliers of cash register systems. This represents the first significant milestone in the technical preparation of the system and a key step towards ensuring sufficient time for the development, testing, and implementation of the necessary solutions prior to the system’s launch.

The published documentation includes core technical materials for system integration, including specifications, contact information, and an overview of further planned steps. The Financial Administration has declared its intention to proceed transparently and to provide information well in advance, enabling all relevant stakeholders—particularly developers and suppliers of cash register systems—to prepare for the changes without major complications.

At the same time, a high-level project timeline has been released. According to this schedule, 2026 should see the launch of a testing environment, the deployment of functionalities within the MOJE daně (My Taxes) portal, and the introduction of the MOJE EET application for small businesses. The pilot operation of the system is planned to begin on 1 January 2027, with full rollout expected from February 2027.

As part of the preparations, the Financial Administration also plans to organize expert seminars for developers and providers of cash register solutions, aimed at presenting the technical documentation in detail and addressing practical issues related to implementation. The first seminar is scheduled for the second half of June 2026.

From the perspective of businesses, this stage primarily concerns the technical preparation of the project. The practical impact on their obligations will depend mainly on the final form of the forthcoming legislation. However, it is already clear that without timely preparation of IT solutions, the launch of operations may present challenges for businesses.
