Czech Republic: Simplification of top-up tax information returns confirmed
Constituent entities can utilize exemptions from filing information returns under the top-up tax framework, subject to meeting notification requirements by June 30, 2026.
The Czech financial administration issued a press release (Czech) confirming that constituent entities in the Czech Republic can utilize exemptions from the obligation to file an information return under the top-up tax framework. This development responds to the newly issued OECD Multilateral Competent Authority Agreement on the Exchange of GloBE Information. The Czech Republic is included on the updated list of signatory states.
Under the exemption, Czech constituent entities may file a notification of compliance with the exemption conditions instead of a simplified information return. To utilize this exemption, the following conditions must be met:
- Filing of the group-wide information return (GIR) for the calendar year 2024 reporting period by June 30, 2026, in an eligible jurisdiction listed by the OECD (which includes EU member states and certain other countries such as the UK, Switzerland, Canada, or South Korea)
- Reporting of this fact to the Czech tax authority by the constituent entities of the group in the Czech Republic by June 30, 2026
- Provision of the information contained in the central filing (the GIR) to the Czech Republic by December 31, 2026, in accordance with the relevant multilateral agreements
If these conditions are not met, the Czech constituent entities will have to file a simplified information return in the Czech Republic.
Additional filing details
Although the general deadline for submitting the information return for the calendar year 2024 reporting period in the Czech Republic is July 1, 2026, submitting the notification by June 30, 2026, is recommended to satisfy the OECD agreement's conditions.
The information return for the entire group can also be filed centrally through the Czech financial administration, as the Czech Republic is a participating jurisdiction. The required forms are specified in the relevant decree, and the portal for electronic filing is expected to become operational in the coming days.
The deadline for filing tax returns for the calendar year 2024 reporting period is November 2, 2026. Constituent entities must file two separate tax returns: one for the Czech top-up tax and one for the allocated top-up tax.
