Permanent establishment in Czechia — when it arises and what follows

The term permanent establishment is purely a tax one and has nothing to do with business premises in the trade-licence sense. It serves a single purpose: to let the Czech state tax the profit that a foreign entrepreneur — a tax non-resident — generates on its territory. If such an establishment arises for you in Czechia, part of your income becomes taxable here, even though your company is seated or has its tax home elsewhere.

It does not concern only builders and factories, as the name might suggest. It can also catch out a smaller entrepreneur or sole trader who gradually does more in Czechia than originally planned. If you are only considering entering the Czech market, we described the basic steps in the overview of what to arrange before starting a business in Czechia as a foreigner. This piece follows on with a question that comes later — from when the Czech state has the right to tax part of your activity.

What a permanent establishment is and why it matters

A permanent establishment is defined by the Czech Income Tax Act (Act No. 586/1992 Coll., §22(2)). In simple terms it is a fixed place or facility through which a non-resident carries on their activity on Czech territory — typically an office, a workshop, a shop or a branch. Whereas an ordinary non-resident taxes only selected income from Czech sources here, the arising of a permanent establishment "moves" the taxation of the profit it generates to Czechia.

Importantly, a permanent establishment is not an entry in any register but a factual state. It arises by meeting the statutory definition, not by "setting something up". It is therefore worth knowing the three situations in which it most often happens.

When it arises — place, time and agent

The first and clearest case is a fixed place for carrying on activity — a so-called "bricks-and-mortar" establishment. An office, workshop or shop that you have available in Czechia and genuinely do business from creates a permanent establishment, as a rule, already from the very first day, without any time condition.

The second case is building sites and construction or assembly projects, and likewise the provision of services. Here a time test applies: the establishment arises only once the activity exceeds six months in any period of twelve consecutive calendar months. It need not be six continuous months — the individual periods are added together, which is easy to overlook with repeated contracts.

The third case is a dependent agent — a person who habitually concludes contracts in Czechia on behalf of the non-resident that are binding on that company, and who does not act as an independent intermediary. Even without an office of their own, such an agent's activity can create a permanent establishment for the company.

Double taxation treaties have the final word

Domestic law is only the start. If the entrepreneur is a resident of a state with which Czechia has a double taxation treaty, that treaty takes precedence — and it often modifies the definition of an establishment. Most commonly it extends the time test for building sites from six to twelve months, sets out exceptions (for example, a warehouse used solely to store goods does not form an establishment) and deals separately with international transport.

The practical conclusion is simple: never rely on §22 alone, but also look at the specific treaty between Czechia and your country. A Slovak entrepreneur is governed by treaty No. 100/2003 Coll. of International Treaties, an Austrian or German one by another — and it is precisely these that decide whether and from when an establishment has actually arisen.

What follows for the business

Once an establishment arises, specific obligations follow. The company must register with the Czech tax authority within the set deadline, keep records of the establishment's activity and file an income tax return in which it taxes the profit attributable to that establishment. Only the part of the profit the establishment would have achieved had it acted as an independent enterprise is taxed — not the entire worldwide income.

The rates are standard: for legal entities income tax is 21%, for individuals 15%, or 23% on the part of the base above the statutory threshold. How a company's profit is calculated exactly and what can be claimed we set out in the article on corporate income tax for an s.r.o. — rates, dividends and costs. A VAT obligation may arise in parallel, but that is assessed under its own rules and does not automatically coincide with the existence of an establishment.

A registered seat alone does not create one

For an entrepreneur running the company from abroad, one thing matters: the registered-seat address or a correspondence address does not automatically create a permanent establishment. What decides it is where the activity is actually carried on and by whom — not where your seat is registered. A company seated in Prague whose director genuinely works and makes decisions from abroad does not, by that fact alone, create a Czech establishment (beyond the company's own tax residency). What can all be managed remotely we covered in the piece on running a Czech company from abroad.

That is exactly why order in your documents and a reliable, credible address are a good foundation — comfortably in a carefully managed house for just thirty companies. The address gives you a representative seat; whether a permanent establishment arises is decided only by your real activity on Czech territory.

Conclusion

A permanent establishment is a tax term that determines when a foreign entrepreneur taxes part of their profit in Czechia. It arises through a fixed place of business (as a rule from the first day), through a building site or services once six months are exceeded, or through the activity of a dependent agent — and the double taxation treaty always has the final word. When an establishment arises, it brings registration, a tax return and the taxation of the profit that belongs to it. A registered seat in Prague alone does not create one; what decides it is where and how you actually do business.

Frequently asked questions

Does a virtual office in Prague create a permanent establishment for me?

The registered-seat address or a correspondence address alone does not create a permanent establishment. What is decisive is where and how the activity is actually carried on, not where your seat is registered. If you genuinely run the company from abroad and have neither a fixed place for carrying on activity nor a dependent agent in Czechia, no establishment arises for you by virtue of the address. The Czech s.r.o.'s own tax residency is a separate question — that follows from its seat and place of management.

From when does a permanent establishment arise when providing services?

For the provision of services and for building sites a time test applies: an establishment arises once the activity exceeds six months in any period of twelve consecutive calendar months. The periods are added together and need not be continuous. If, however, the entrepreneur is a resident of a state with a double taxation treaty, that treaty may extend the test — for building sites often to twelve months. So always look at the specific treaty as well.

What do I have to do if an establishment arises for me?

The company must register with the Czech tax authority within the set deadline, keep records of the establishment's activity and file an income tax return. Only the profit attributable to that establishment is taxed, not worldwide income — the rate is 21% for legal entities and 15%, or 23%, for individuals. It is advisable to discuss the assessment and the cross-border profit split with a tax adviser.
