Wondering When Your Tax Refund Will Arrive?
Have you filed your Czech tax return but still haven’t received your refund? Here’s how the refund timeline works.
Under the Czech Tax Code, an overpayment is refunded within 30 days from the date the overpayment arises. In practice, the start of that 30-day period depends on when and how you file.
Filing deadlines and refund timelines
1) Paper tax returns filed on time (filed by April 1, 2026)
If you file on time, the 30-day period typically starts after the standard filing deadline.
For the 2025 tax year, this means refunds for returns filed by April 1, 2026 should be processed by the next working day after the 30-day period ends — i.e. by May 4, 2026 (because May 1 is a public holiday and May 2–3 fall on a weekend).
2) Electronic tax returns filed before April 1, 2026
The same timeline applies as for paper returns filed on time — i.e. by May 4, 2026.
3) Paper tax returns filed after April 1, 2026
If you submit a paper return late, the 30-day refund period generally starts the day after the tax return is submitted.
4) Electronic tax returns filed after April 1, 2026
Electronic filing has an extended statutory deadline in 2026 (for the 2025 tax year): May 4, 2026.
So if you file electronically after April 1, the refund is processed within 30 days from the electronic filing deadline — i.e. no later than June 3, 2026.
Again, if you submit late, i.e. electronically after May 4, 2026, the 30-day refund period generally starts the day after the tax return is submitted.
5) Tax returns filed through a tax advisor (deadline July 1, 2026)
If your return is filed by a tax advisor (under a power of attorney), the deadline is July 1, 2026.
In that case, any overpayment refund should be processed within 30 days from this deadline — i.e. no later than August 1, 2026.
Tip to get your refund sooner
If you want the refund as quickly as possible, it’s best to file on time (and ideally as early as possible) — extended deadlines can delay when the 30-day period even starts.
