Inadvertent permanent establishment

When does the obligation to register and tax profits abroad arise?

An unintentional permanent establishment can arise for a Czech company abroad even without establishing a branch, for example, due to the long-term work of employees, the provision of services, or a place from where the business is effectively managed. This can result in the registration and taxation of profits in the foreign country. In this article, you will learn which activities create this risk, how to set up work abroad, and what to check before expanding.

Unwanted permanent establishment

Key takeaways

An unintentional permanent establishment has significant tax implications. Its automatic creation can lead to high penalties and default interest, as ignorance of the rules is no excuse and is often interpreted as a lack of due care.
The definition of a permanent establishment is based on the OECD Model Tax Convention. Article 5 describes it as a “fixed place of business through which the business of an enterprise is wholly or partly carried on,” which is crucial for the allocation of taxing rights.
The OECD Commentary is key to interpreting double taxation treaties. It evolves, and states may have reservations to it; for the CZ-AT DTT, for example, it is necessary to refer to the 2003 version, which affects the outcome of a dispute.
A permanent establishment can be created in three main ways. We distinguish between a fixed place of business PE, a service PE, and a dependent agent PE.

Unintentional Permanent Establishment – A Silent Threat to International Business

This automatic creation has significant tax implications. A lack of intent or knowledge offers no protection against penalties from foreign tax authorities. In the event of a tax audit, ignorance of the rules is often interpreted as negligence, increasing the risk of high fines and late payment interest.

Our lawyers at ARROWS International deal with permanent establishment issues on a daily basis in more than 70 countries worldwide. For an immediate solution to your situation, write to us at consultation@arws.cz

Basic Tax Concepts: Where to Find the Rules of the Game?

The basic definition of a Permanent Establishment (hereinafter "PE") is based on Article 5 of the so-called OECD Model Tax Convention. This convention serves as a crucial reference framework for allocating the right to tax profits between the state of residence and the source state.

In the OECD Model Tax Convention, a PE is described as "a fixed place of business through which the business of an enterprise is wholly or partly carried on".

When interpreting a specific Double Taxation Treaty, it is essential to refer to the accompanying Commentary on the OECD Model Tax Convention. It is important to realize that the Commentary evolves, and countries may have specific reservations about different versions (for example, the CZ-AT DTT requires reference to the 2003 version of the Commentary). ARROWS knows these details, which are decisive in the outcome of a dispute.

Distribution of Risks and Taxation: The Three Pillars of an Unintentional PE

The creation of a PE is typically divided into categories, such as a fixed place of business (fixed place PE), a service PE, and a dependent agent PE.

Permanence Criteria: How is a "Fixed Place" PE Created?

A so-called Fixed Place Permanent Establishment requires a certain degree of geographical and temporal permanence in the performance of activities. This includes any premises available to the enterprise (even implicitly) that are used to carry out its core business activities.

It is necessary to correctly distinguish that a PE is not created if only auxiliary or preparatory activities are carried out at the location, such as mere storage of goods or purchasing. The creation of a PE also entails the need to comply with local obligations that go beyond tax law. For example, under Czech legislation, business premises must be properly marked and a legal title for their use must be documented.

If a foreign PE were created in the Czech Republic and failed to meet these obligations, it would face penalties under the Trade Licensing Act, including the suspension of its business activities for up to one year. ARROWS ensures compliance with obligations towards registers and regulators.

Correct Profit Attribution (Authorized OECD Approach)

Once a PE is created, the key question is what portion of the company's profits is subject to taxation in the foreign state. It is always only the profits that can be attributed (allocated) to the PE.

For profit allocation, a modern approach called the Authorized OECD Approach (AOA) is applied. It fully recognizes and reports intra-company transactions, which are valued in accordance with the arm's length principle.

Incorrect application of the AOA or the use of an older (so-called non-AOA) approach can lead to the foreign tax authority taxing a larger portion of profits than is fair, without deducting your intra-company costs (e.g., payments for management services or license fees). This risk can significantly reduce the profitability of cross-border operations.

Our lawyers will prepare legal opinions and analyses to determine the optimal method for establishing the tax base. We also utilize the instrument of a binding ruling on the method of determining the tax base for a tax non-resident. Our lawyers are ready to help you – write to us at consultation@arws.cz

Home Office: When the Couch Becomes the Company's Office

Working from home abroad (Work From Anywhere, WFA) represents the most current and least expected risk for corporations, which has become massive following the spread of flexible work arrangements.

The professional community is fully aware of this risk. For example, the Danish Tax Agency confirmed the creation of a PE for a Swedish company on the basis that its CEO worked 40% of the time from his home in Denmark.

This case showed that for a PE to be created, it is not essential whether the activity is aimed at the Danish market. The CEO's activity was purely internal and related to the management of the company in Sweden. However, its significant influence on the daily management of the company and the permanent, planned nature of the work were sufficient to establish a Permanent Establishment. This is a critical insight for all top managers.

According to information from experts, the Czech Tax Administration holds a similar view on planned and permanent work from home, which clearly indicates a global trend of tax authorities tightening their stance on WFA.

FAQ – Legal Tips for Remote Work: Responsibility and Prevention

1. What is the difference between occasional and planned work from home?

The key is intent and permanence. Occasional or sporadic use of a home office is less risky. However, if the work is predetermined and planned (e.g., a specific percentage of time), the risk of creating a Permanent Establishment is very high. Want to know how to set the rules? Write to us at consultation@arws.cz.

2. Which position is the riskiest?

The riskiest positions are those with decision-making authority (e.g., CEO, CFO, sales directors) whose activities have a significant impact on the daily management of the company. It is precisely for these positions that tax authorities most often argue for the creation of a PE. Need legal assistance in identifying at-risk positions? Contact us at consultation@arws.cz.

3. We have internal agreements stating that a PE is not created. Is that sufficient?

A contractual agreement with an employee helps, but it is not decisive for foreign tax authorities. The decisive factor is always the actual activity carried out in the given territory. It is therefore necessary to have comprehensive and enforceable internal policies. Connect with us at consultation@arws.cz and get a tailor-made legal solution.

Service Permanent Establishment: The 183-Day Trap

A service permanent establishment under Section 22(2) of the Income Tax Act arises from the provision of services (e.g., technical, IT, or consulting) in a foreign state if the time limit set in the relevant DTT is exceeded.

The most common limit for the creation of a service permanent establishment is 183 days in any twelve-month period. This applies, for example, to the provision of IT services.

Tax authorities (for example, in Austria and the Czech Republic) often aggregate the duration of service provision even across different individual contracts and service packages if there is a material connection within a twelve-month period. Entrepreneurs often make the mistake of tracking only the length of individual contracts, not the total time accumulated in the given territory, which leads to unintentionally exceeding the limit.

Legal consultation with ARROWS protects against fines by assessing the risks of time aggregation in advance and proposing contractual structures (e.g., for IT and consulting firms).

Construction Site Permanent Establishment: Risks in Subcontractor Chains

For construction and assembly projects, the test for creating a PE is typically shorter, usually 6 months. The existence of this type of permanent establishment is assessed based on a single location factor, a time factor, and a material factor (the delivery of a complete construction project).

Many general contractors underestimate the danger posed by subcontractors. Even if only your subcontractors are active on the construction site, the time spent on the site by all suppliers is counted cumulatively toward the period relevant for the creation of the general contractor's PE.

Our Prague-based firm ensures the preparation or review of contracts so that the risks arising from the time tests of subcontractors are managed transparently. Need legal help? Contact us at consultation@arws.cz

Dependent Agent Permanent Establishment

Another type of unintentional permanent establishment is the dependent agent PE. This situation arises if a person acts in a foreign state who is dependent on the enterprise (e.g., economically) and who has the authority to conclude contracts on behalf of the enterprise, or habitually negotiates such contracts.

If the person is an independent broker or agent, a PE is not created. The crucial assessment is whether the agent has the ability to act in your favor and bind the company without your subsequent authorization. How can you avoid problems? It is key to review all contracts with commercial agents and distributors and ensure that they perform only auxiliary and preparatory roles, without the authority to conclude binding contracts. For an immediate solution to your situation, write to us at consultation@arws.cz

Strategic Prevention: Internal Policies, Training, and Audits

Tax authorities always assess the actual state of affairs and the factual activity in a given territory, not just what is written in a contract. Therefore, robust internal policies are key evidence to demonstrate that the company is actively managing and mitigating the risk.

A Work From Anywhere policy must contain clear limits on the length of stay abroad and a list of positions that are not permitted to work across borders (e.g., C-level managers, sales representatives, purchasers). It must also include a monitoring protocol (e.g., recording of stays).

Drafting internal policies that protect against fines and penalties is one of the key services that ARROWS offers. Our lawyers have many years of experience with this agenda. Our lawyers are ready to help you – write to us at consultation@arws.cz

Professional Training as a Compliance Tool

Most unintentional permanent establishments arise due to errors by employees who are unaware of the tax consequences of their trips abroad.

ARROWS provides professional training for employees or management, including a certificate, with the aim of raising awareness about the risks of Service PEs and WFA. Effective training demonstrates active risk management to tax authorities and minimizes subsequent penalties. Need legal help? Contact us at consultation@arws.cz

FAQ – Most Common Legal Questions about Permanent Establishment

1. Can a permanent establishment be created even without the presence of personnel?

Yes, the creation of a permanent establishment is not always linked to the physical presence of employees. For example, the existence of specific computer equipment, such as a server, can under certain conditions lead to the creation of a PE, and the physical presence of personnel is not essential for such an assessment. If you are facing a similar issue, contact us at consultation@arws.cz.

2. What is a service permanent establishment and what is the most common time test?

A service PE arises from providing services (including consulting and technical) in a foreign state. In many DTTs, this time test is set at 183 days in any twelve-month period. The problem arises with the aggregation of time, where the time spent on separate but materially related projects is also added up. Need legal help determining the time test? Write to us at consultation@arws.cz.

3. Can a PE be created for me abroad even if I have no clients there?

Yes, it is possible. The precedent from the Danish Tax Agency confirmed that even planned and permanent work from home by a key manager (CEO) abroad can lead to the creation of a PE, even if his activities only concern the internal management of the company and do not target the local market. Connect with us at consultation@arws.cz and get a tailor-made legal solution that also addresses internal risks.

4. What are the risks if I fail to register an unintentionally created permanent establishment?

You primarily face an unregistered tax liability in the foreign state and the risk of high penalties from the foreign tax administrator, including late payment interest. In an extreme case, this can lead to international double taxation, where the same profits are taxed by both the Czech and the foreign tax authorities. Do not hesitate to contact our firm: consultation@arws.cz.

5. Can ARROWS help me with the allocation of profits to a permanent establishment?

Yes. If a PE is created, it is crucial to correctly determine its tax base. We help clients apply the modern Authorized OECD Approach for effective profit allocation, including the preparation of documents required by law. For an immediate solution to your situation, write to us at consultation@arws.cz.
