This article provides data-driven insights into the Czech Republic’s (CZ) corporate tax regime for companies as of 2025. Key figures, special tax provisions, and surcharges are covered to help international business owners and professionals clearly understand the country’s current approach to corporate taxation.
Overview of Corporate Income Tax in CZ (2025)
The Czech corporate tax system applies a flat tax rate to company profits, assessed on a corporate basis. The following table summarizes the main aspects of the regime:
| Corporate Tax Base | Tax Rate (Percentage %) | Tax Type | Currency |
|---|---|---|---|
| Corporate profits | 21% | Flat | CZK |
The standard corporate income tax (CIT) rate for 2025 is 21% on all taxable corporate profits. There are no progressive brackets; all qualifying company profits are taxed at this uniform rate.
Special Surtax on Excess Profits (Windfall Surtax)
For the years 2023 to 2025, a targeted surtax applies to large banks and energy sector companies if their profits exceed certain thresholds. The parameters for this windfall tax are as follows:
| Surtax Rate (Percentage %) | Applies to | Threshold for Application | Period |
|---|---|---|---|
| 60% | Large banks & companies in the energy sector | Profits exceeding 120% of the average CIT base from 2018-2021 | 2023-2025 |
This means that, for qualifying entities, any annual profit above 120% of their average taxable base from the years 2018–2021 will be subject to a significant 60% surcharge in addition to the standard CIT during these specific tax periods.
Capital Gains and Holding Periods
Information regarding capital gains holding periods (minimum or maximum required) is currently not publicly available for the 2025 tax year. Typically, such data may be updated on an annual basis or may not be relevant to the standard corporate tax regime in CZ.

Pro Tips for Navigating Czech Corporate Tax (2025)
- Verify whether your business falls under the definitions of a large bank or energy company, as the special 60% windfall surtax applies only to this group for 2023–2025. Planning profit timing accordingly can affect your tax exposure.
- Maintain accurate records of your CIT base for each of the calendar years 2018–2021 if you operate in targeted sectors, since the surtax threshold relies on these historical averages.
- Factor in the flat 21% CIT rate when modeling the after-tax profitability of new or ongoing business projects in the Czech Republic.
- Monitor official sources for changes in holding period requirements or other corporate tax rules, as adjustments may be introduced annually: visit https://www.financnisprava.cz/ for the latest information.
Key Considerations for CZ Corporate Tax in 2025
The Czech Republic maintains a straightforward corporate tax system with its flat 21% rate for all company profits, free from progressive brackets. However, targeted sectors—especially banking and energy—should closely monitor the windfall surtax, which can materially increase the tax burden on excess profits through 2025. As always, careful attention to profit calculation and record-keeping is advisable, especially if historical averages impact your liability.
