How to Register a Company in Estonia: 3 Routes for Foreign Founders
Foreign founders can set up an Estonian company in more than one way. The right route depends mainly on whether everyone involved can sign digitally with an accepted Estonian digital ID, whether the company structure is straightforward, and whether you want a new entity or an existing one.
This guide compares three practical routes: online formation through the e-Business Register, a notary or authorised representative, and the purchase of an existing company. It focuses on the private limited company (osaühing, or OÜ), the form most commonly used by small and growing businesses. Requirements, documents and processing times depend on the applicant and the case; confirm them before applying.
At a glance: three ways to establish or obtain an Estonian OÜ
| Route | Best suited to | Main point to check |
|---|---|---|
| Online registration | Founders able to sign with an accepted Estonian digital ID | Every required signer must be able to authenticate and sign |
| Notary or power of attorney | Founders who cannot complete the digital process or have a more complex case | Notarial formalities, identification, translations and authorisation |
| Purchase of an existing OÜ | Buyers who need to take over an existing legal entity | Full legal, financial, tax and operational due diligence |
1. Register online through Estonia’s e-Business Register
For many founders, the online route is the most direct way to create a new OÜ. The application is submitted through the official Estonian e-Business Register, administered by the Centre of Registers and Information Systems (RIK). The portal supports company establishment, register queries, later amendments and annual-report filings.
Online formation requires the people who must sign the application to use a supported digital identity and to sign the same application. The accepted methods include an Estonian ID card, an e-Residency digital ID, Smart-ID or Mobile-ID. If a founder, board member or other required signer cannot use one of the supported methods, the online path may not work for that application. Check the current signer requirements in RIK’s instructions for establishing a private limited company.
Typical online-registration steps
- Choose the company name and legal form. Check name availability and distinguishability in the official register before ordering a domain or marketing materials.
- Decide who owns and manages the company. Confirm the founders, shareholdings, management-board members and beneficial owners before completing the application.
- Arrange the registered address and contact-person requirements. If the company uses an address outside Estonia, Estonian rules may require a licensed contact person. Check the requirement for your exact address and management-board situation.
- Prepare the company details. Select the principal activity, financial year and articles-of-association options, and enter correct contact details.
- Review and sign. Each required person signs digitally; review the application carefully before using the signature PIN.
- Pay the applicable fee and submit. RIK currently lists a €265 state fee for electronic establishment of a private limited company. Verify the amount and payment instructions shown in the portal before applying.
RIK’s current guidance also describes how founders confirm share-capital contributions. Do not treat capital as a fee or assume payment mechanics are the same in every case; check the latest RIK guidance on contributions and the instructions displayed in your application.
Where e-Residency fits
The e-Residency programme provides a government-issued digital identity that can let eligible non-residents access Estonian online services and sign documents digitally. It is not Estonian citizenship or a residence permit, does not determine your personal tax residence and does not guarantee that a bank or payment provider will accept your company.
Applying for e-Residency and incorporating a company are separate steps. Allow time for the identity-card application and collection process, then check that every person who must sign has a compatible digital identity.
2. Use an Estonian notary or an authorised representative
A notarial route can be appropriate when a required signer cannot complete the online process, when the transaction involves more complex ownership or documents, or when the company is being established through a representative. A notary verifies identity and formalities and prepares or authenticates the documents required for the specific case.
Some founders authorise a representative under a power of attorney. Depending on where it is signed and the document format, the power of attorney may need notarisation, an apostille or legalisation, and a sworn translation into Estonian. Requirements vary by country and by the notary handling the matter. Confirm the document wording and formalities before signing abroad; a general template may not be sufficient.
Notarial assistance does not remove the need for accurate shareholder, management, address, beneficial-owner and business-activity information. Ask in advance which participants must attend or sign, what original documents are required, whether remote notarisation is available in your circumstances, and which costs are payable to the notary, translator and service provider.
Our notary and power-of-attorney registration route explains how Eesti Consulting can help coordinate the process. If the company needs an Estonian registered address or contact person, review the separate legal-address service and contact-person service.
3. Buy an existing Estonian company
Buying a ready-made company is different from incorporating a new OÜ: the legal entity already exists, and the buyer usually acquires shares and completes the related ownership and management changes. The transfer may be quicker in some circumstances, but speed should never replace due diligence. An existing VAT number, bank account or licence is not a guarantee that it will remain active or usable after a change of ownership.
Before signing, obtain current register documents, annual reports, accounting records, tax information, details of contracts and liabilities, beneficial-owner information, bank and payment-provider status, and written disclosure of any disputes or guarantees. Confirm whether the company has traded, whether any VAT registration is active and appropriate for the intended activity, and whether licences or agreements can be transferred. Use the official RIK register search to verify public company details independently.
Our checklist for buying a ready-made company in Estonia covers key checks before signing. You can also review the available Estonian ready-made company options. Ask for the exact scope of the share transfer, included services, exclusions, payment schedule and handover documents in writing.
What to arrange after registration
Registration is the start of the company’s obligations, not the end of the process. Put a calendar in place for bookkeeping, annual reporting, register updates and tax filings. An Estonian company must submit an annual report even if it had little or no activity; check the company-specific reporting period and deadline in the official register.
VAT registration is not automatic simply because an OÜ is incorporated. Whether registration is required or useful depends on the company’s activity, transactions and applicable rules. Cross-border sales, digital services, employees, inventory and management outside Estonia can create additional obligations. Ask an Estonian accountant or tax adviser to review the actual model before the first invoice.
Plan payment services early as well. Banks and fintech providers apply their own onboarding, risk and documentation checks, so incorporation alone does not promise an account. Prepare a clear business description, ownership chart, expected transaction profile, customer and supplier details, and evidence of the source of funds. See our business banking solutions for options to consider.
Which route should you choose?
- Choose online formation if the company is straightforward and all required signers can use accepted Estonian digital identities.
- Ask about the notary route if a signer lacks a compatible digital ID, documents need formal verification, or ownership arrangements are more complex.
- Consider a ready-made company only when taking over an existing entity serves a real business need and independent due diligence confirms its status.
Do not choose solely on a headline price or a promised registration speed. Compare the total setup and annual costs, who is responsible for filings, the address and contact-person arrangements, the banking pathway and the tax consequences where the owners live and manage the business.
