For the third consecutive month, the Czech government has reduced the excise tax on diesel to the minimum possible amount of eight koruna per liter. This decision, which was recently approved and remains valid until the end of June, is being framed by officials as a response to ongoing market instability.
The Use of Executive Waivers
Alena Schillerová has characterized the current economic climate by stating, “The global situation in the fuel market remains very complex due to tensions in the Middle East.” To address this, the cabinet is utilizing a specific provision in the tax code that allows for the mass remission of taxes during “extraordinary, especially natural, events.”
This method of tax reduction is controversial because, under the Constitution, taxes are typically established through laws approved by Parliament rather than by government decree. Under normal circumstances, the government does not have the authority to unilaterally dictate tax rates.
A Shifting Definition of “Extraordinary”
The classification of what constitutes an “extraordinary event” has undergone significant changes. In 2022, a state position determined that energy price fluctuations did not qualify as an extraordinary event, noting that such events are primarily natural disasters, epidemics, or large-scale industrial accidents.
However, by 2026, the scope of these events was expanded to include “war conflict.” The Ministry of Finance now argues that unstable oil supplies from specific regions justify the continued classification of the current situation as an extraordinary event, thereby allowing for the extension of tax remissions.
Potential Future Scenarios
As the government continues this “diesel routine,” several outcomes are possible. The administration could eventually decide that the global fuel market is no longer sufficiently complex, leading them to end the tax waivers.

Alternatively, the government may choose to follow the precedent set by the Fiala administration after the invasion of Ukraine by proposing the reduced diesel tax rate to Parliament for formal approval as a law. A third possibility is that the cabinet maintains the current waivers indefinitely, though such a practice could potentially be halted by a court citing the principle of the separation of powers.
