Opening an Estonian Subsidiary: A Guide for Foreign Companies

Oct 30, 2026 | Guide, Legal

A foreign company can establish an Estonian subsidiary to develop local operations, enter new markets or organise part of its business within a separate company. The subsidiary is commonly registered as a private limited company, known as an OÜ, with the foreign parent as its shareholder. It has its own legal identity, records and obligations.

Registration by a foreign corporate founder requires preparation of the parent company’s documents, confirmation of signing authority and decisions about management and funding. This guide explains the main steps, the difference between a subsidiary and a branch, and the accounting arrangements to consider before the new company starts trading.

Foreign Ownership of an Estonian Subsidiary

An Estonian OÜ can have a legal person as its founder, including a foreign company. The foreign parent can be the sole shareholder or hold shares alongside other investors. The subsidiary’s management board runs the company; ownership and management are separate roles.

The official investment guide for Estonia describes the OÜ as a separate company with limited shareholder liability. This separation can be useful when a group wants an Estonian entity to hold contracts, employ staff or operate a distinct part of its business.

Limited liability should still be assessed alongside the actual arrangements. For example, a parent that guarantees a subsidiary’s borrowing takes on obligations under that guarantee. Incorporation also does not establish the tax treatment of every activity carried out by the group.

Estonian Subsidiary and Branch Compared

An Estonian subsidiary is a separate legal person, while a branch forms part of the foreign company. The foreign company remains responsible for obligations arising from its branch’s activities. The Estonian State Portal confirms that a branch operates without creating a separate subsidiary.

The choice depends on which entity will contract with customers, own assets, employ people and receive payments. The legal and tax consequences in Estonia and the parent company’s jurisdiction should be assessed together before the structure is selected.

Documents Required From the Foreign Parent Company

The foreign parent must be identifiable, and the authority of the person acting for it must be established. Tallinn’s registration guidance identifies an official certificate proving the foreign company’s existence as a requirement for a foreign corporate founder.

The exact document package depends on the parent’s jurisdiction, legal form, representation rules and ownership structure. It may include:

  • a current business-register extract or equivalent certificate;
  • constitutional or representation documents where the extract is insufficient;
  • a decision authorising incorporation, where required;
  • identification and authority documents for the signatory;
  • ownership-chain information identifying the ultimate beneficial owners;
  • a power of attorney if a representative will complete incorporation.

Foreign-certified documents may need an apostille or legalisation unless an applicable agreement provides an exemption. The Commercial Register Act sets out the principle for foreign-certified documents. Translation requirements also need to be checked for the particular documents.

The document list should be confirmed before certifications or translations are ordered. An extract confirming the parent company’s existence may not, on its own, establish signing authority or explain a multi-level ownership chain.

Registration and Signing Arrangements

Before incorporation, the parent company needs to agree on the subsidiary’s name, activities, management board, representation rights, address and financial year. The share capital and arrangements for funding the company’s initial operations should also be settled.

The Estonian Chamber of Notaries’ incorporation guidance identifies beneficial owners and capital contributions among the matters to prepare. Where a foreign address will be used, the applicable contact-person requirement must also be checked.

The official e-Residency guidance directs foreign-company subsidiary registrations to an Estonian notary. A representative’s e-Residency card does not, by itself, establish that the standard online process used by an individual founder is available to the foreign parent.

Once the corporate documents and signing authority have been checked, the incorporation documents can be finalised and the registration application submitted through the agreed route. The overall timeframe includes obtaining and certifying foreign documents, arranging translations where required and completing the registry process. It therefore depends on the parent company’s circumstances as well as the time needed to process the application.

Remote Incorporation Through a Representative

An Estonian subsidiary may be established through an authorised representative without the parent company’s representatives travelling to Estonia. BBCTallinn’s company formation service includes registration by power of attorney, subject to preparation of documents suitable for use in Estonia.

The wording, scope and signing formalities of the power of attorney should be confirmed before it is executed abroad. Notarial remote participation may also be available where accepted by the notary. The appropriate route depends on the participants, their identification arrangements and the documents involved.

Banking Arrangements After Registration

The subsidiary’s registration and its application for a bank or payment account are separate processes. Incorporation does not guarantee acceptance by a particular provider.

The account provider may request information about the parent company, ultimate beneficial owners, intended transactions, source of funds and the subsidiary’s business activities. Preparing this information alongside the incorporation documents helps the group plan the next stage of establishing its Estonian operations.

Accounting and Tax Obligations of an Estonian Subsidiary

The subsidiary needs accounting records that distinguish its transactions from those of its parent. Funding, services and expenses paid between group companies should be supported by contracts and appropriate records. The group should agree how these documents will be provided to the subsidiary’s accountant.

Estonia generally taxes profit when it is distributed. The standard tax on a net dividend payment is currently calculated at 22/78, according to the Estonian Tax and Customs Board’s dividend guidance. Other payments and expenses can also create tax liabilities. Retained profit should therefore not be confused with an exemption from all company taxes.

VAT registration is a separate question. The general 40 000 € threshold concerns qualifying transactions whose place of supply is Estonia. Certain purchases from abroad can create additional registration obligations, including before that threshold is reached. The subsidiary’s planned sales and purchases should be assessed against the official VAT registration guidance.

The parent’s home-country treatment also requires assessment. Estonian incorporation alone does not settle the taxation of group payments or activities carried out elsewhere.

Accounting should be arranged before the subsidiary begins trading so that incorporation expenses, initial funding and transactions with the parent are recorded from the outset.

Frequently Asked Questions

Establishing a Subsidiary With a Foreign Corporate Shareholder

A foreign company can be the sole shareholder of an Estonian OÜ. The registration documents must establish the parent company’s existence, the authority of its representative and the relevant ownership information.

Using a Representative’s e-Residency Card

An e-Residency card identifies its individual holder. It does not replace the foreign parent’s corporate documents or establish the holder’s authority to act for that company. The official e-Residency guidance directs foreign-company subsidiary registrations to a notary.

Registering Without Travelling to Estonia

Incorporation through an authorised representative may be available. The power of attorney and supporting documents must meet the requirements for use in Estonia. Signing arrangements should be confirmed before documents are executed abroad.

VAT Registration After Incorporation

Incorporation does not automatically register the subsidiary for VAT. Registration requirements depend on its transactions, including relevant sales and purchases from abroad. They should be assessed separately from company formation.
