Company Formation in Estonia: How to Register an OÜ in 2026

Registering an OÜ in Estonia: Two Routes Into One Register

Company formation in Estonia almost always means registering an osaühing, or OÜ, in the Commercial Register through the Company Registration Portal of the Centre of Registers and Information Systems. The route depends on a single question: can every founder and every member of the management board sign with an Estonian ID card, an e-resident digital ID, Mobile-ID or Smart-ID? If they can, the application is prepared, signed and submitted online, and the e-Residency programme says the registrar’s review usually takes one business day. If anyone involved cannot sign that way, or if a founder is itself a company, the OÜ is registered through a notary office in Estonia.

Choosing the Estonian Legal Form

The Commercial Code recognises six forms of business; for a founder from abroad the OÜ is almost always the right one. For the country as a whole, see our Estonia overview.

Form	Statutory minimum capital	What it suits
Osaühing (OÜ), private limited company	EUR 0.01 share capital per shareholder	Trading, services and holding; the default choice
Aktsiaselts (AS), public limited company	EUR 25,000 share capital	Large ventures and shares meant for listing
Branch (filiaal) of a foreign company	None; not a separate legal person	A foreign company trading in Estonia on its own liability; registered through a notary
Sole proprietor (FIE)	None	Not a legal person and must be situated in Estonia, so not open to most non-residents

The OÜ is what English speakers call the Estonian LLC or limited company: its shareholders are not personally liable for its debts, and management sits with the management board (juhatus). While share capital is below EUR 2,500, the shareholders answer for the company’s obligations up to that figure in total, counting what they have already paid in, if the company goes bankrupt with too few assets. OÜ simply abbreviates osaühing, and the business name must carry Osaühing or OÜ at its beginning or its end.

Who Can Register Online, and Who Needs an Estonian Notary

The portal accepts signatures made with an Estonian ID card, the e-resident digital ID, Mobile-ID or Smart-ID, and nothing else, which is why the e-resident card is the practical way in for a founder without an Estonian document. Before applying, note that:

• you apply yourself, in the Police and Border Guard Board environment; applications made through intermediaries such as law firms or formation agents are not accepted;
• the review generally takes 30 calendar days, an approved card usually reaches the pickup location 2 to 5 weeks later, and the programme puts the whole process at about 6 to 8 weeks;
• the card is collected in person, with fingerprints, at an Estonian embassy or consulate, a service point in Estonia or a mobile pickup point;
• e-Residency is a digital identity and confers no tax residency, no right of residence and no right of entry;
• first-time applications from Russian and Belarusian citizens are not reviewed, whatever residence permit they hold elsewhere, and citizens of a further list of countries, among them Iran, Nigeria and Syria, are considered only under narrow exceptions.

Without a supported ID, or where a founder is a legal person such as a foreign parent company, the application goes through a public notary in Estonia. Board members without a supported ID can later sign the annual report on paper and have an accountant upload it.

Requirements for an Estonian OÜ at a Glance

Requirement	What the rules say
Shareholders	One or more, natural or legal persons, of any nationality or residence
Management board	At least one member, with no residency or nationality condition
Address	An Estonian legal address from a licensed virtual office provider, or the board’s address abroad together with a licensed contact person in Estonia
Share capital	At least EUR 0.01 per shareholder, paid in full before the application is submitted and confirmed by the founders; capital above EUR 50,000 is paid to a court deposit account
Name	Latin letters only, distinguishable from registered and reserved names and from trademarks protected in Estonia; it can be reserved for six months
Main activity	One planned principal activity from the EMTAK classification; other activities remain allowed
Beneficial owners	Named in the founding application: anyone holding more than 25% or exercising control by other means

Only a licensed trust and company service provider, an advocate or law firm, a sworn auditor or audit firm, a tax representative of a non-resident or a notary may be the contact person. Documents delivered to the contact person count as delivered to the company, yet the contact person cannot act for it. The appointment runs for a fixed term, usually a year, and letting it lapse without a replacement is a ground for starting the deletion of the company.

The Registration Procedure, Step by Step

1. Name and activity. Check the name in the Business Register name query, reserve it if you wish, and choose the EMTAK code matching your expected main source of turnover in the first financial year.
2. Address. Select an Estonian address from the national address data system, or enter the foreign address and add the contact person.
3. Persons, capital and articles. Add the board members and founders, fix each contribution and complete the mandatory options of the standard articles.
4. Beneficial owners. Enter them in the application.
5. Optional requests. Voluntary VAT registration and employee registration can be sent with the application; the Tax and Customs Board receives them once the company is entered.
6. Signing and submission. Every person signs in the portal, the board confirms the capital has been paid and the application goes to the registrar, whose proceeding term appears on the application page.

The registrar either enters the company or issues a ruling asking for deficiencies to be put right. No separate tax registration follows: the eight-digit registry code is also the company’s tax identifier.

Setting Up an Estonian Company From the UK

Founders living in the United Kingdom follow the same procedure. The e-resident card can be collected at the Estonian embassy in London or at a mobile pickup point in Edinburgh. Tax residence needs thought before the first contract: Estonia treats every company incorporated under its law as Estonian tax resident, while HMRC applies the case-law test of central management and control, under which a company incorporated abroad but run from the United Kingdom can be UK resident. The double taxation treaty between the two countries is in force and settles dual residence, but it is cleaner to know in advance where the board really takes its decisions.

Estonian banks look for a business connection with Estonia and do not treat e-Residency as one, so most companies founded by e-residents use EEA payment institutions instead; see our page on bank accounts for Estonian companies.

An Estonian OÜ as a Holding Company

Estonia does not tax company profit as it is earned. Corporate income tax arises only when profit leaves the company, at 22/78 of the net distribution, which equals 22% of the gross amount; the planned rise was cancelled, so the rate stays at 22% in 2026. For a holding company that means:

• dividends and gains received by the OÜ are not taxed while they stay inside it;
• dividends from a company resident in Estonia, the EU, the EEA or Switzerland, outside low-tax territories, in which the OÜ held at least 10% when the dividend arrived can be passed on without further corporate income tax, as can other foreign dividends at that holding where the underlying profit was taxed abroad;
• since 2025 dividends are taxed only at company level, the old 7% withholding on dividends to individuals surviving only for profit taxed at the former 14/86 rate.

A foreign parent company forms the OÜ through an Estonian notary rather than online. Estonia has concluded 70 comprehensive double taxation agreements, 66 of them in force, and the principal purpose test of the Multilateral Instrument applies to arrangements made mainly for a tax benefit.

What Starts on the Day of Registration

Obligation	Rule
Corporate income tax	22/78 on dividends and other distributions, declared and paid on the TSD return by the 10th of the month after payment
Board member remuneration	22% income tax and 33% social tax
VAT	24% standard rate since 1 July 2025; registration compulsory once turnover with Estonia as the place of supply exceeds EUR 40,000 in a calendar year; monthly returns by the 20th
Annual report	Filed in XBRL with the e-Business Register within six months of the year end by every company, dormant ones included; it does not replace tax returns
Audit or review	Audit once two of these are exceeded: revenue EUR 5 million, total assets EUR 2.5 million, 50 employees; review at the lower thresholds of EUR 2 million, EUR 1 million and 24 employees
Beneficial owners	Changes submitted in the portal as they happen; unchanged data confirmed with each annual report; closed to general public search since 10 July 2026

VAT is where online sellers are most often caught out. Registration below the threshold needs a clear connection to Estonia, such as staff there or goods stored in or moving through the country; where goods never pass through Estonia, VAT and the OSS scheme belong where the business is really carried on.

When Buying an Existing Company Is the Better Route

Because a new OÜ is usually entered within a business day once everyone signs digitally, a ready-made company saves no real time for a founder who holds a supported ID. It is worth considering when a client, landlord or tender asks for an earlier registration date, which the register records and nobody can alter; when a VAT number already granted matters, bearing in mind it lasts only with genuine Estonian activity; and when the buyer cannot sign online and would deal with an Estonian notary either way.

How We Help With an Estonian Formation

We can form a new OÜ or supply a ready-made one, prepare the founding or transfer documents and the portal filings, help you put together the application to a bank or payment institution and, where we have a working contact at a suitable bank, make an introduction, with the decision left wholly to the bank. If the company is to use your address abroad, we can arrange the contact person through a trust and company service provider licensed by the Financial Intelligence Unit; the contact person receives documents for the company, has no power to act for it and is entered in the commercial register. The e-Residency application itself is yours to submit, because the programme accepts none made through intermediaries.

Frequently Asked Questions About Company Formation in Estonia

Do I need e-Residency to register a company in Estonia?

No, but you need a way of signing that the Company Registration Portal accepts: an Estonian ID card, the e-resident digital ID, Mobile-ID or Smart-ID, held by every founder and every board member. If any of them has none, the company is registered through a notary office in Estonia instead, and the same applies when a founder is a company. e-Residency is simply the usual way for a foreigner to obtain a supported ID.

How long does company formation in Estonia take?

Once everyone has signed and the application is submitted, the e-Residency programme says the registrar’s review usually takes one business day, and the application page shows the term within which the registrar must decide. The longer wait is often the digital ID, which the programme puts at about 6 to 8 weeks from application to collection. Through a notary, the timing depends on the notary’s identity and document checks.

What is the minimum share capital of an Estonian OÜ?

EUR 0.01 per shareholder, so three shareholders need at least three cents of share capital. It is paid before the application is submitted and the founders confirm it in the portal; capital above EUR 50,000 goes through a court deposit account. Below EUR 2,500 of share capital, shareholders answer for the company’s debts up to that amount in total if its assets fall short in bankruptcy. Until 2023 the minimum share capital was EUR 2,500.

Is an Estonian OÜ the same as an LLC?

It is the closest Estonian equivalent of a US LLC or a UK private limited company: a separate legal person, run by its management board, whose shareholders are not personally liable for its obligations. It is not a pass-through entity, though. The OÜ is itself the taxpayer, paying corporate income tax when it distributes profit, and it is Estonian tax resident because it is incorporated in Estonia.

How does company formation in Estonia compare with Germany?

A German GmbH needs notarised articles, which can now be done by video, and share capital of at least EUR 25,000, half of that minimum paid before registration is applied for; the UG variant may have less capital but must pay it in full. An Estonian OÜ needs EUR 0.01 share capital per shareholder and no notary when everyone signs online. Germany also taxes profit as it is earned, while Estonia waits for a distribution. See company formation in Germany.

Can a Russian or Belarusian citizen register a company in Estonia?

Estonian company law sets no nationality condition, but first-time e-Residency applications from Russian and Belarusian citizens are not reviewed, so online registration is normally closed to them and only the notary route remains, subject to the notary’s own checks. The company itself is bound by EU sanctions under Regulation 833/2014, and banks apply their own restrictions. Our page Estonia (in Russian) covers these points for Russian speakers.
