What obligations does a company have in Czechia during the year (a business calendar)

Most of a company's obligations in Czechia recur every year in a similar rhythm. Once you know them, they stop being a source of stress and become routine — the nagging "did I forget something?" simply disappears. For a foreign or Slovak director who often runs the company remotely, a clear calendar is the best insurance against late-filing penalties.

The overview below is not an exhaustive list — rather a map of the year's main milestones that concern a typical s.r.o. The specific dates shift slightly from year to year: when a date falls on a weekend or public holiday, the next working day applies, so always check the exact days for the year in question. The rhythm itself, however, stays the same year after year.

The start of the year — returns and property taxes

The year opens for a company with the real-estate tax. If the company acquired a property last year or something changed with it, it files the return by 31 January; the tax itself is then payable by the end of May, and for a larger amount in two instalments, the second of which falls at the end of November. The return for the road tax is also due by the end of January — but since the 2022 amendment it concerns only selected goods and trailer vehicles over 12 tonnes, not ordinary passenger cars.

The most important spring deadline is the corporate income tax return for the previous year. The basic deadline is three months after the year-end, that is by the start of April. With electronic filing, which is mandatory for companies with a data box, it extends by a month (to the start of May), and when the return is prepared by a tax adviser, out to six months (by the start of July). The tax itself is payable within the same deadline. The details and the differences between the deadlines are covered in the article on tax returns.

What recurs every month and quarter

Some obligations do not wait for the year-end but run continuously. VAT payers file both the return and the control statement by the 25th of the following month; while the VAT period may be monthly or quarterly, an s.r.o. files the control statement monthly in all cases. The standard VAT rate is 21%, the reduced one 12%. Anyone not yet registered who is weighing whether and when to register will find an explanation in the article on VAT.

If the company employs staff, monthly contributions are added. Social and health insurance for employees is paid by the 20th of the following month, together with the overviews for the insurers; wages are settled and the wage tax advance is withheld. What a first employee entails is summarised in the article on employing people. Companies with a higher tax bill also pay income tax advances — half-yearly (by mid-June and mid-December) or quarterly (by mid-March, June, September and December) depending on their last known tax; anyone paying less than CZK 30,000 in tax a year pays no advances at all.

Financial statements, the general meeting and publication

A company not only files a return but also draws up financial statements for the past year. These must be approved by the general meeting, no later than six months after the end of the accounting period — for a calendar year, by the end of June. It is not a mere formality: without approved statements you cannot, for example, validly decide on paying out a share of the profit.

The company then publishes the approved statements in the collection of deeds of the Commercial Register — within 30 days of approval, and at the latest within 12 months of the balance-sheet date. Publication is checked by the court, and neglecting it is among the most common lapses by companies. Example: an s.r.o. with a calendar year approves its 2025 statements at the general meeting by the end of June 2026 and files them in the collection of deeds within 30 days.

How to keep the whole year under control

It sounds like a lot of dates, but in practice it is mainly the accountant who holds the calendar together, tracking most of the deadlines for you and preparing the documents in good time. The second pillar is the data box — most communication with the authorities now runs through it, and companies have it set up by law, so calls and decisions reach you electronically wherever you happen to be.

For a director running the company remotely, that is good news: almost everything can be handled electronically and without a trip to Prague. All you need is your documents in order, a credible registered seat — for instance in a house that hosts only thirty companies — and a reliable accounting partner.

Conclusion

The business calendar in Czechia is not complicated — it is simply regular. The key milestones, namely the returns in spring, the monthly VAT and payroll, and the financial statements with the general meeting by mid-year, recur in the same rhythm every year. Once you have them planned in advance and an accountant on hand, the company runs without needless penalties and surprises.

Frequently asked questions

What are a company's main tax deadlines in Czechia during the year?

The year opens with the real-estate tax, whose return is filed by the end of January. Spring brings the corporate income tax return — within three months of the year-end, a month longer with electronic filing and up to six months with a tax adviser. VAT and the control statement run continuously, due by the 25th of the following month, along with monthly contributions for employees. By the end of June the general meeting must approve the financial statements.

Does a company with a data box have to file its return electronically?

Yes. Companies entered in the Commercial Register have a data box set up by law and therefore file their tax return electronically. Electronic filing carries a deadline a month longer than paper filing, so instead of three months after the year-end they have four. If the return is prepared by a tax adviser, the deadline extends to six months.

What happens if a company misses one of the deadlines?

A late return or late payment of tax risks a penalty and default interest, both of which grow with the length of the delay. Forgetting to publish the financial statements in the Commercial Register can be sanctioned by the court with a separate fine. Most problems can be avoided by having an accountant track the deadlines and by communicating with the authorities through the data box.
