Czech s.r.o. Filing & Tax Deadlines 2026: A Calendar for Foreign Owners
Updated: 2026-07-24 · Tax year 2026. This guide is general and informational, not tax advice. For your company’s exact obligations, work with a Czech accountant.
Setting up a Czech s.r.o. (the local limited company) is the easy part. Keeping it compliant from abroad is where owners get caught out — because a Czech company has recurring duties whether or not it trades, and Czech deadlines don’t wait for you to be in the country. This is the practical calendar of what a foreign-owned s.r.o. must file in 2026.
Every Czech s.r.o. keeps double-entry accounts
Unlike a sole trader, a company (s.r.o.) is always required to keep double-entry bookkeeping (podvojné účetnictví) — there is no simplified “tax records” option. From day one you need to record every invoice, bank movement and payroll item. This feeds three separate filing streams: corporate income tax, VAT (if registered), and payroll (if you have employees or pay director’s remuneration).
If you are still at the formation stage, start with our guide on registering a Czech s.r.o. as a non-resident.
Annual: corporate income tax + financial statements
- Corporate income tax rate: 21% on profit. The full picture — tax base, dividends, loss carry-forward — is in our Czech corporate tax guide.
- Corporate tax return for 2025 is due 1 April 2026 if you file yourself, 1 May 2026 if you file electronically via data box (an extra month), or 1 July 2026 if a registered tax adviser files for you.
- Financial statements (balance sheet, profit & loss, notes) must be filed into the Commercial Register (justice.cz) — typically within 30 days of approval and no later than 12 months after the balance-sheet date. Missing this is a common and avoidable penalty for foreign owners who assume the tax return is enough. It isn’t — the register filing is separate.
Monthly / quarterly: VAT (if registered)
You must register for Czech VAT once turnover passes CZK 2,000,000 in a calendar year (or immediately at roughly CZK 2,536,500 ≈ EUR 100,000), and you can register voluntarily earlier. Once registered:
- VAT return + payment: by the 25th of the following month (monthly payers) or following the quarter (quarterly payers). If the 25th is a weekend/holiday it moves to the next working day.
- Control statement (kontrolní hlášení) and, for EU sales, EC Sales List (souhrnné hlášení) — same 25th deadline.
- Filing is electronic only. See our Czech VAT guide and note where VAT is heading under EU reform in e-invoicing in the Czech Republic (ViDA).
Monthly: payroll (if you have employees or pay the director)
If your s.r.o. employs anyone — including paying remuneration to the director (jednatel) — payroll duties kick in, due by the 20th of the following month:
- withheld income-tax advance on wages to the tax office,
- social and health insurance — employee share (11.6%) plus employer share (33.8%) of gross pay,
- the new monthly employer report JMHZ (in full effect from 1 July 2026).
Wages cannot fall below the 2026 minimum of CZK 22,400/month. You must also register as an employer at the social-security authority (ČSSZ), the health insurer and the tax office within 8 days of the first hire.
Key 2026 deadlines at a glance
| When | Obligation | Applies to |
|---|---|---|
| By the 20th of each month | Payroll: tax advance, insurance, JMHZ | s.r.o. with staff/director pay |
| By the 25th of each month | VAT return, control & EC sales list | VAT-registered s.r.o. |
| 1 Apr / 1 May / 1 Jul 2026 | Corporate income tax return for 2025 | every s.r.o. |
| Within 30 days of approval | File financial statements to Commercial Register | every s.r.o. |
| 15 Mar / 15 Jun / 15 Sep / 15 Dec | Corporate tax advances (if last tax was high enough) | profitable s.r.o. |
What happens if you miss a deadline
Czech penalties apply fairly automatically. A late tax return triggers a late-filing penalty plus default interest on unpaid tax; a late VAT control statement starts at CZK 1,000 and rises sharply after an official notice; and failing to file financial statements into the Commercial Register can lead to fines and, in serious cases, action against the company. Distance is not an excuse the authorities accept — which is exactly why remote owners delegate the calendar.
Frequently asked questions
Does my s.r.o. have to file anything if it didn’t trade?
Yes. A dormant s.r.o. still files a corporate tax return and financial statements. Keeping accounts and meeting the register deadline is mandatory regardless of activity.
When is the corporate tax return due in 2026?
For the 2025 period: 1 April (paper), 1 May (electronic via data box), or 1 July if a registered tax adviser files for you.
Do I need to be in the Czech Republic to file?
No. Everything is filed electronically, typically through your Czech accountant and the company data box. You can verify your own company’s public filings any time via how to check a Czech company.
