If you’ve been putting off your Czech tax return, don’t panic just yet – while the paper filing deadline has already passed, there is still time to submit your personal income tax return electronically.
The main deadline for filing in paper form ended on Wednesday, April 1, 2026, but many people in the Czech Republic are now choosing the easier route – online filing.
And they’re not alone. According to the Czech Financial Administration, more than 1.6 million tax returns had already been submitted by the basic deadline. Out of these, over 1.46 million came from individuals, and more than 62% of all submissions were filed electronically.
That’s a pretty clear sign of where things are heading: tax filing in Czechia is becoming more digital, more accessible, and more user-friendly.
So… Can You Still File Your Taxes?
Yes, if you haven’t submitted your 2025 personal income tax return yet, you can still file it electronically.
Here are the key deadlines for the 2025 tax return filed in 2026:
Important Tax Return Deadlines in Czechia
- April 1, 2026 – paper submission deadline (already passed)
- May 4, 2026 – electronic submission deadline
- July 1, 2026 – if your return is filed by a tax advisor, attorney, or if you are subject to a mandatory audit
So if you missed the paper deadline, online filing is now your main option.

Why More People Are Filing Online
The Czech Financial Administration has been actively encouraging people to use digital tools for several years now — and it’s clearly working.
According to Simona Hornochová, Director General of the Czech Financial Administration, interest in electronic filing keeps growing every year. She also pointed out that the MOJE daně (My Taxes) portal helps taxpayers not only submit their return more comfortably, but also reduce mistakes while filling it in.
For many expats, this is especially good news.
Let’s be honest, dealing with taxes in another country can feel stressful enough without having to physically visit an office, print forms, or guess whether you filled in the right boxes. The online system is designed to make the process smoother and in many cases, much faster.
Tax Refunds Are Already Being Processed
If you filed your return on time and applied for a tax refund, the Czech tax office has already started processing both returns and refund requests.
Here’s what you should know:
If you filed by April 1, 2026
If you submitted your tax return on time by the basic deadline and requested a refund, your overpayment should be returned within 30 days after the deadline, which means no later than May 4, 2026.
If you file electronically after April 1, 2026
If you’re using the extended electronic deadline and submit your return by May 4, 2026, any refundable overpayment should be sent within 30 days after that date, so no later than June 3, 2026.
If you file late
If your tax return is submitted after the applicable deadline, the refund period still remains 30 days, but it starts from the day your return was actually filed — or from the day you submitted your refund request, if that happened later.
One Important Detail About Tax Refunds
Just because you’ve filed doesn’t automatically mean your refund will be sent immediately.
In order for the refund to be paid out, your tax return must be complete and processable without additional doubts or checks. In other words, the tax office must be able to review it without needing further clarification.
Also, if you have outstanding debts on other taxes, the tax office may use your overpayment to cover those first.
So if your refund doesn’t arrive as quickly as expected, it doesn’t necessarily mean something is wrong — but it may be worth checking whether everything in your filing was submitted correctly.
Tax Offices Also Helped People in Person
Even though the tax system is becoming increasingly digital, not everyone feels comfortable handling tax matters online — especially older residents, people in smaller towns, or those who simply prefer in-person assistance.
That’s why, from mid-February, specialists from Czech tax offices also provided support directly in the field. They offered help with completing and submitting tax returns during more than 270 visits across 125 municipalities throughout the Czech Republic, mainly in places where local tax office branches had previously been closed.
On top of that, thousands of additional questions were answered through consultation hotlines.
This kind of support matters — especially in a country where bureaucracy can still feel intimidating even for locals, let alone foreigners.
Watch Out for Tax Scams Right Now
And now for the important warning: tax season is also scam season.
Whenever deadlines, payments, or tax refunds are involved, scammers tend to become more active. Their goal is usually to get access to your personal data, payment details, or online banking.
This is especially important for expats, because official-looking Czech messages can feel difficult to verify if you’re not fully confident in the language or system yet.
Here are the biggest red flags to watch for:
1. The sender’s email is suspicious
Official emails from the Czech Financial Administration always come from the domain:
@fs.gov.cz
If the message comes from anything else, be cautious.
2. The message creates panic or urgency
Scam messages often try to pressure you into acting quickly, using phrases like:
- “Final warning”
- “Renew your registration”
- “Claim your refund within 3 days”
- “Immediate payment required”
That kind of emotional pressure is a classic scam tactic.
3. It contains strange links or QR codes
If an email or SMS includes a payment link, suspicious QR code, or redirects you outside official government websites, do not click it.
4. The text feels “off”
Some scam messages still contain spelling mistakes, weird formatting, or incorrect institution names — although it’s true that scam messages have become more polished in recent years.
5. The amount is very small
This one surprises a lot of people: scammers often use small amounts like a minor underpayment or a tiny tax refund because it makes people more likely to react quickly without checking carefully.
And one crucial reminder:
The Czech Financial Administration Does NOT Send Payment Links by Email or SMS
This is worth repeating clearly:
The Czech Financial Administration does not send payment links for income tax payments or tax refunds via email or text message.
So if you receive one, don’t trust it.
Final Reminder for Expats in Czechia
If you still need to submit your 2025 personal income tax return, the next key deadline is:
Monday, May 4, 2026
for electronic filing
And if you’re filing through a professional tax advisor or fall under mandatory audit rules, your deadline is:
Wednesday, July 1, 2026
If you’re unsure whether you need to file, whether you can claim a refund, or how to navigate the Czech tax system as a foreigner, it’s always better to sort it out sooner rather than later.
Tax season in Czechia can feel confusing — but you definitely don’t have to figure it all out alone.
