Through e-Residency, tens of thousands of foreigners have established companies in Estonia, hoping to benefit from its attractive corporate tax system, which allows the deferral of income tax until profits are distributed.
However, this expectation can quickly turn into disappointment if a commonly underestimated tax risk is overlooked – permanent establishment. This may result in the income of an Estonian company becoming taxable in the e-resident’s country of residence.
Permanent establishment is a concept in international tax law used to determine when a company has sufficient economic presence in a country for its income to be taxed there.
Business Activities in Another Country
According to the Organisation for Economic Co-operation and Development (OECD) Model Tax Convention, a permanent establishment is a fixed place of business through which the business of an enterprise is wholly or partly carried on. Most double taxation treaties (including those with Finland, China, the United States and India) use the same concept.
Typical examples of permanent establishments include:
- place of management;
- branch;
- office, factory, or workshop;
- farm, plantation, or other place related to agriculture or forestry;
- mine, oil or gas well, quarry, or other natural resource extraction site;
- construction site or building, installation or assembly project, including related supervisory activities, if such activities last longer than 12 months (in many treaties 6 or 9 months).
Example 1
The board members of an Estonian company are e-residents living in Germany and use a rented office in Berlin to make strategic decisions. In this case, the German tax authorities may conclude that the company has a permanent establishment in Germany, as the effective management takes place there.
Dependent and Independent Agents
A permanent establishment usually requires a physical location, such as an office or factory. However, it can also arise through the activities of a company’s representatives.
A permanent establishment may exist if a representative has the authority to conclude contracts on behalf of the company in a given country and does so on a regular basis.
However, a permanent establishment does not arise where an agent, broker, or intermediary acts independently in the ordinary course of their business. An agent is considered independent if they do not act primarily on behalf of a single company.
Example 2
If a sales agent operating in Denmark regularly negotiates and concludes contracts on behalf of an Estonian company established by an e-resident, it may be concluded that the company has a permanent establishment in Denmark.
However, if the same company uses a local broker to sell an office building in Lithuania, the broker is likely considered an independent representative and no permanent establishment arises.
Remote Work May Trigger Tax Obligations Abroad
Remote work has become increasingly common and is also relevant in determining permanent establishment. Working remotely alone does not automatically create a permanent establishment. It arises only if the employee’s presence abroad is business-driven.
This is generally the case when there is a direct link between the employee’s presence and the company’s business activities. In practice, a permanent establishment usually does not arise if the employee stays abroad for less than six months.
Example 3
An employee of an Estonian IT company travels to Spain for one month to work remotely while enjoying the local climate and cuisine. In this case, there is neither a business purpose nor sufficient duration, and no permanent establishment arises.
However, if the same employee travels to India for nine months to recruit employees and clients, their presence has a clear economic purpose for the company. Due to this business-driven activity, a permanent establishment may arise in India.
Legal Implications of a Permanent Establishment
Business operations typically require people, but a permanent establishment may also arise through equipment or facilities that operate without direct human involvement, such as automated production processes.
Activities of a preparatory or auxiliary nature are generally not considered to create a permanent establishment. For example, having accounting, customer support, IT system maintenance, market research or similar support functions abroad does not usually create a permanent establishment.
The above outlines the general principles for determining a permanent establishment. However, real-life situations are often more nuanced, and tax authorities in different countries may interpret the concept of a permanent establishment differently. In case of doubt, it is advisable to seek clarification from a local tax advisor or the tax authority.
The existence of a permanent establishment generally entails registration, accounting and reporting obligations in the foreign country.
Key Tax Principles for E-Residents:
- An Estonian company is automatically an Estonian tax resident.
If you establish a company in Estonia, it is considered an Estonian tax resident and must pay income tax in Estonia (unless a tax treaty provides otherwise). - Estonian tax residency does not automatically exempt the company from tax obligations in other countries.
Estonian tax residency does not preclude taxation in other countries where business activities take place or where the company earns income. - Tax obligations may arise in multiple countries simultaneously.
If an Estonian company has a permanent establishment, for example in Finland, tax obligations arise both in Estonia (as the country of residence) and in Finland (as the country of the permanent establishment).
This does not mean that the company must pay tax on the same income in both countries. Estonia has concluded double taxation treaties with more than 60 countries.
Avoiding Double Taxation
The following principles apply under double taxation treaties:
- If an Estonian company operates only abroad, the income earned there is taxed in that foreign country.
The income of an Estonian company may also be taxed abroad if the management of the company is carried out outside Estonia. - If an Estonian company earns profits abroad through a permanent establishment, dividends distributed in Estonia from those profits are exempt from Estonian income tax.
In such cases, the primary tax liability for an e-resident’s Estonian company arises in the foreign country. - Regardless of where the company operates, non-business-related expenses are taxed in Estonia (unless such expenses are taxed abroad as part of profit attributable to the permanent establishment).
Even if no corporate income tax liability arises in Estonia, the obligation to file declarations may still exist.
For example, to avoid double taxation of dividends paid from foreign income, the company must submit form TSD Annex 7, where foreign income is declared.
Practical Recommendations for Risk Mitigation
The responsibility for determining tax obligations lies with the entrepreneur.
If the risk of a permanent establishment is overlooked, the company may not benefit from Estonia’s favourable tax system and, in the worst case, this may result in double taxation or penalties.
Since the ultimate responsibility for determining tax obligations rests with the entrepreneur, the following practical recommendations should be considered to mitigate risks related to permanent establishment and to benefit from Estonia’s tax system:
- Create real economic activity in Estonia (hire employees, appoint a local board member, rent office space, hold board meetings physically in Estonia, etc.).
- Avoid making ongoing business decisions and repeatedly concluding contracts in the same location outside Estonia.
- Take into account risks related to individuals, especially where representatives have authority to conclude contracts or employees work remotely for extended periods.
- Assess risks related to permanent establishment at least once a year and more frequently when business activities change.
- Properly document business activities in writing.
- Be proactive: familiarise yourself with local rules and ensure proper registration and reporting.
- Contact the local tax authority for clarifications or binding advance rulings.
- In case of doubt, consult a legal or tax advisor.
While establishing a company in Estonia through e-Residency is convenient and fast, the tax risks related to permanent establishment should not be taken lightly. Otherwise, the entrepreneur may face an unexpected letter from the tax authority or even penalties.
