Tax Authority Decision – How to Challenge It in the Czech Republic
Received a decision from the Czech tax office and disagree with it? Maybe they reassessed your taxes, rejected your objection, or issued a decision without properly considering your evidence. In moments like these, the key is not to panic—but also not to delay. You can fight a tax decision, but only within strict time limits and through specific legal channels.

Common search queries include: “how to appeal tax office decision,” “what to do if Czech tax office reassesses tax,” “challenge tax authority ruling,” or “what is the deadline to appeal tax decision.” This article explains how to respond if you disagree with a decision—and why time is your most important asset.
What is a tax decision?
A tax decision is a formal act that concludes a certain phase of the tax process—such as reassessment, denial of a request, penalty, or closure of an audit. It must be issued in writing, include justification, and contain instructions on how to appeal.
Once the decision is delivered (see our earlier article on delivery), a 30-day appeal period begins. This deadline is strict and non-extendable.
How can you challenge a decision?
The main method is to file an appeal under Section 109 of the Czech Tax Code. In your appeal, you can:
argue why the decision is unlawful or incorrect,
submit additional evidence or highlight procedural errors,
propose changes or cancellation of the decision.
The appeal must be filed with the same tax authority that issued the decision. They will check it for formal completeness and pass it to the superior body (typically a regional tax directorate) for a full review.
What if you miss the deadline?
Then you’re usually out of luck. The Czech Tax Code does not allow for late appeals. That’s why it’s essential not to waste time—even if you want to consult a lawyer or review the situation first.
I’ve seen cases where people submit excellent appeals—40 days after delivery. Unfortunately, tax authorities will reject them without even looking at the merits. A well-written but late appeal is still a lost case.
What does an appeal need to contain?
Your appeal must be clear, well-structured, and specific. Simply writing “I disagree” is not enough. You need to explain what the tax office got wrong, what should have been considered, and what you propose instead. For complex cases, I highly recommend involving a lawyer—ineffective appeals are surprisingly common.
