Deadlines in Czech Tax Proceedings – Overview, Examples, Risks
When the tax office sends you a letter, the clock is ticking – and often faster than you think.
“I got something from the tax office, but I haven’t opened it yet.” I hear this way too often – and it always makes me nervous. In tax proceedings, time doesn’t run by your watch – it runs by the law. Missing a deadline can mean losing your right to appeal or being hit with penalties. In this article, I’ll explain which deadlines apply, how they’re calculated, and why it’s absolutely crucial to know when the clock starts ticking.

Wondering how long the tax office has to reply? Or how many days you have to appeal a tax decision? What if you pick up the letter late – when does the deadline start? In this article, I cover everything you need to know about deadlines in Czech tax proceedings – with examples and frequent mistakes that can cost you a fortune.
What types of deadlines apply in tax proceedings?
Czech tax law (the Tax Code) contains several types of deadlines:
1. Deadlines for taxpayers (your time to act)
These are deadlines for submitting appeals, objections, tax returns, or explanations. They vary – from 15 days to 30 days, depending on the type of action. Missing the deadline often means the decision becomes final and unreviewable.
Example:
Appeal against a tax decision = 30 days from delivery
2. Deadlines for the tax office (their time to decide)
In some cases, the authority must decide within a time limit – usually 30 days or 6 months, depending on complexity.
Note: If the office fails to meet the deadline, it doesn’t automatically mean you win – but you can claim inaction and push back.
3. Subjective and objective deadlines
Subjective deadlines start from the moment you become aware of an issue.
Objective deadlines are fixed (e.g., 3 years from delivery).
How are deadlines calculated?
The deadline starts the day after the document is delivered.
If the letter arrives on August 1, the first day of the deadline is August 2.
Calendar days are used, unless the law says otherwise.
If the last day falls on a weekend or holiday, the deadline is extended to the next working day.
⚠️ Beware of delivery fiction: if you don’t pick up a letter in time, it may be considered delivered on day 10.
What if you miss the deadline?
You can request a restoration of the previous state (navrácení v předešlý stav), but only if:
You prove serious reasons (e.g. hospital stay, accident)
You submit the request within 15 days of the obstacle ending
⚠️ Excuses like “I was on holiday” or “I forgot” are rarely accepted.
Advice from your lawyer
Don’t wait. When you get a letter from the tax office, note the date immediately and start counting. If you’re unsure, contact a lawyer immediately – even one consultation can save your case.
I’ve seen clients lose thousands because they missed a deadline by just one day.
