Open a Subsidiary or Branch in Estonia: Practical Guide

To open a subsidiary in Estonia or register a branch, foreign companies first compare two routes: incorporating a separate Estonian company (usually an OÜ) or registering an Estonian branch of the existing foreign company. They are legally different structures. The right choice depends on who should carry contractual risk, where decisions and people will be located, and how the group will handle tax, accounting and reporting in each country.

This guide explains the practical differences, the Estonian registration process and the main compliance questions to resolve before applying. It is general information, not legal or tax advice for a particular group.

At a glance: subsidiary or branch?

Question	Estonian subsidiary (OÜ)	Estonian branch
Separate legal person?	Yes. The OÜ is a company established under Estonian law.	No. The branch is part of the foreign company.
Who is liable?	Generally, the OÜ is liable with its own assets, subject to statutory exceptions and guarantees.	The foreign parent is liable for obligations arising from the branch’s activities.
Who owns it?	The parent company or other shareholders own shares in the OÜ.	No shares are issued for the branch; it is an establishment of the parent.
When is it often considered?	When the group wants a distinct Estonian contracting entity, a local subsidiary, or clearer separation of operations.	When the foreign company wants to operate permanently in Estonia in its own name and accepts direct parent-company liability.

These are starting points, not a recommendation. Corporate-law separation does not by itself settle tax residence, permanent-establishment exposure, VAT, employment or regulatory duties in Estonia or the parent’s home country.

What Estonian law says about a foreign branch

Under section 384 of Estonia’s Commercial Code, a foreign company that wants to permanently offer goods or services in Estonia in its own name must register a branch in the Commercial Register. The law is explicit that a branch is not a legal person and that the foreign company is responsible for the obligations arising from the branch’s activities. A branch director directs and represents the branch and organises its accounting.

This means a branch is not a liability shield or a second Estonian company. Contracts entered into through it remain connected to the foreign company. A parent should consider whether its existing insurance, financing, internal approvals and home-country filings permit this structure. The branch may also create a taxable presence or reporting obligations in Estonia, depending on the activity and facts.

When an Estonian OÜ may be a better fit

An OÜ is a separate legal person registered under Estonian law. It can contract in its own name, employ staff and hold assets separately from its parent. A subsidiary may therefore be easier to distinguish in customer contracts, local operations and group accounting. This does not erase parent-company risk where the parent gives guarantees, directs conduct in a way that creates liability, or where other legal rules apply.

Estonia no longer applies the former fixed €2,500 minimum share-capital requirement for an OÜ. The founders set the share capital in the articles, and the statutory nominal value of a share can be as low as one cent. A very small capital figure is not automatically sensible: choose an amount that reflects the business plan, expected costs, creditor expectations and any licensing or financing requirements. Confirm the current rules in the Commercial Code and get advice on the intended structure.

Registering an Estonian branch: the usual stages

1. Confirm that branch registration is the right route. Map the planned Estonian activity, customers, staff, premises and duration. A short-term project, a regulated service or a remote sales model may raise different questions from a permanent local operation.
2. Check the foreign parent’s status and authority. Gather current registry evidence, constitutional documents and the corporate approval authorising the Estonian branch. The Estonian registrar can require supporting documents and information about the foreign company and its representatives.
3. Appoint the branch director or directors. The director represents the branch and organises its accounting. Agree internally who can sign, whether directors act jointly, and how local records and parent-company oversight will work.
4. Prepare the Estonian application and supporting papers. The application identifies the parent and branch, their legal forms and addresses, the branch’s activity, directors and representatives. Foreign public documents may need certification or an apostille/legalisation, and documents not in Estonian may need an acceptable translation. Confirm the exact requirements for the parent’s jurisdiction with the registrar before commissioning documents.
5. File with the e-Business Register. The official registration portal describes the branch route and directs applicants to start the relevant application. The e-Business Register portal is the state’s official environment for applications and public register information. Signing and filing options depend on the applicant, documents and available electronic identification; foreign parent documents may require a different route.
6. Complete the post-registration setup. Confirm the registry entry, tax registrations, bookkeeping, invoicing, payroll if staff are employed, and any sector-specific licences. Also check whether the branch needs an Estonian contact person under the rules applicable to its management and address; do not assume every branch has the same requirement.

Documents to prepare

For an initial document checklist, expect to discuss the parent company’s current registry extract or certificate of existence, constitutional documents, the resolution establishing the branch, the branch name and address, a description of the activity, and information about directors and persons authorised to represent the parent. The registrar may require specified originals, certified copies, translations or authentication. The final list depends on the parent’s country and the particulars of the application, so use the register’s instructions for the case rather than relying on a generic checklist.

Keep the parent’s legal name and registration number consistent across the documents. Differences in transliteration, expired extracts, missing signing authority or a resolution that does not clearly authorise the branch can delay an application. If the parent has several layers of ownership, prepare accurate beneficial-owner information and be ready to explain the group structure.

Tax, VAT and accounting: what a foreign group should model

Corporate income tax. Estonia’s system generally taxes company profits when they are distributed or otherwise treated as taxable distributions, rather than simply when accounting profit is earned. From 2025, the standard company-level rate is 22/78 of the net distribution. The Estonian Tax and Customs Board (EMTA) explains the rules for taxing distributed profits. A foreign parent and an Estonian branch are not insulated from the parent country’s tax rules; the attribution of profit, tax treaty, location of people and business substance matter.

VAT. The general Estonian registration threshold is €40,000 of relevant Estonian-place-of-supply turnover from the beginning of the calendar year, subject to the detailed statutory rules and exceptions. Cross-border supplies, intra-Community transactions and non-resident businesses can have different registration consequences, including obligations before the threshold is reached. Check EMTA’s current guidance on VAT threshold calculation before invoicing.

Accounting and annual reporting. A branch must organise its accounting, and the foreign parent remains responsible for branch obligations. An Estonian OÜ has its own accounting records and annual-report duties. The Business Register says annual reports are generally due within six months after the end of the financial year; see its current annual-report guidance. Set up a calendar for local deadlines, and separately check the parent’s home-country consolidation and filing requirements.

Cross-border management. If directors make key decisions or perform core work from another country, that country may assert tax residence or a permanent establishment under its domestic law and the relevant treaty. An Estonian registration or e-Residency card does not, by itself, determine where the founder personally pays tax or prevent foreign obligations. Estonia’s e-Residency team explains the concepts of permanent establishment and dual residence. Model the actual operating pattern with advisers in both jurisdictions.

Branch or subsidiary: a practical decision checklist

• Do customers, lenders or regulators require an Estonian company as the contracting party?
• Is the parent willing to be directly liable for the branch’s Estonian obligations?
• Will the business hire employees, lease premises, hold stock or conduct regulated activities in Estonia?
• Where will management decisions and day-to-day work actually take place?
• Can the parent provide the certified corporate documents required for a branch, and maintain group-level oversight?
• Has the group compared accounting, tax, VAT, employment, banking, insurance, audit and closure costs—not only the initial registration fee?

Answering these questions before filing helps avoid choosing a structure based only on headline registration speed or tax marketing. An OÜ and a branch can both be appropriate, but their legal responsibility and ongoing administration are different.

How Eesti Consulting can help

We first review the parent company’s jurisdiction, activity, ownership and preferred operating model so the document checklist reflects the actual case.

Frequently asked questions

Is an Estonian branch a separate company?

No. Under the Commercial Code, a branch is not a legal person. The foreign company remains liable for obligations arising from the branch’s activities.

Does a subsidiary protect the foreign parent from every claim?

No structure removes all risk. An OÜ is a separate company, but guarantees, parent conduct and statutory exceptions can still create exposure. Obtain legal advice for the group’s contracts and governance.

Does Estonia still require €2,500 share capital for an OÜ?

No. The old fixed minimum was removed. The founders set the share capital under the current rules; a low statutory minimum does not mean that minimal capital is right for every business.

Will Estonia tax every euro of retained profit immediately?

Generally, Estonia taxes company profits when distributed or otherwise treated as taxable distributions. The rate and treatment depend on the payment and current law; foreign tax obligations may also arise where the business is managed or operates.

Is registration enough to start operating?

No. Check the activity-specific licence, VAT position, accounting and reporting duties, payroll, banking, address and contact-person requirements before trading.
