Czech Republic Approved Changes to the Minimum Tax Act

The key change is the extension of the deadline for submitting the so-called GloBE Information Return (GIR) to 15 months after the end of the accounting period (for the transitional year up to 18 months, i.e., by June 30, 2026 for the 2024 year). The same deadline applies for notifications if the return is filed in another country where the group operates. The tax return and payment of the tax must now be made no later than 22 months after the end of the accounting period, i.e., by October 31, 2026.

The Ministry of Finance of the Czech Republic has also prepared new electronic forms for submitting these returns and filings, which must be submitted exclusively electronically in XML format.

These changes are intended to ensure that large companies pay a minimum effective tax in the EU, regardless of where they operate.
