The Estonian OÜ (osaühing, a private limited company) is the form that e-Residency materials describe as the most common choice for e-residents, accounting for 99% of the businesses they register. Estonian law also allows a public limited company (AS), a sole proprietor (FIE), a branch of a foreign company and two kinds of partnership. This article compares them on liability, share capital, governance and access for non-residents, and then looks at when an Estonia holding company makes sense.
What Is an Estonian OÜ?
Estonian private limited company meaning
An OÜ is a legal person registered in the Estonian Commercial Register, owned by one or more shareholders. Shareholders are not personally liable for the company's obligations, and the company answers for them with its own assets. Most people who search for an Estonia LLC are looking for exactly this form, although the OÜ is a distinct Estonian entity and not a copy of the US LLC.
How an OÜ is run
A single founder is enough, and the registration can be completed entirely online. The e-Residency program lists the OÜ as available to e-residents, and its state fee for online registration is €265 according to the e-Residency knowledge base. If you want the full registration sequence, it is covered in how to register a company in Estonia, and the e-resident route in particular in Estonia e-Residency company formation.
Estonian OÜ vs Other Legal Forms
The table below summarizes the forms listed in the e-Residency guidance on company types. It covers the points most founders ask about first.
| Form | Legal person? | Liability | Minimum capital | Founders and governance | Open to e-residents? |
|---|---|---|---|---|---|
| OÜ (private limited company) | Yes | Shareholders not personally liable | €0.01 | 1 founder minimum; online registration | Yes, most common |
| AS (public limited company) | Yes | Shareholders not personally liable | €25,000 | 1 founder minimum; supervisory board of at least 3 members and an auditor | Yes, rarely used |
| FIE (sole proprietor) | No | Owner | None | One person, based in Estonia | Not typically |
| Branch of a foreign company | No | The foreign company is liable for the branch's obligations | Not applicable | Registered through a notary | Depends on the parent company |
| TÜ (general partnership) and UÜ (limited partnership) | Partnership forms | TÜ: shared among partners; UÜ: at least one partner with unlimited liability | €0 | 2 founders minimum | Available, registered only in specific circumstances |
Public limited company (AS)
An AS also limits shareholder liability, but it must have a supervisory board of at least three members and an appointed auditor, and its share capital starts at €25,000. Those requirements make sense for companies planning to raise money from many investors or to list securities. For a small operating or holding business they add cost and administration without adding protection that an OÜ lacks.
Sole proprietor (FIE)
A FIE is a person who trades under their own name and is not a legal person. The e-Residency site states that FIEs must be situated in Estonia and are therefore not typically available to e-residents. The Tax and Customs Board adds that an e-resident who does register as self-employed must file annual income tax returns even with no Estonian taxable income, and pay quarterly social tax advances set by the state budget rather than by profit.
Branch of a foreign company
A branch carries on business in Estonia for an existing foreign company and has no separate legal personality. The foreign company is liable in Estonia for obligations arising from the branch's activities, and registration in the Commercial Register requires a notary. A branch fits a group that wants one legal entity abroad and accepts that Estonian losses stay with the parent.
General and limited partnerships
In a general partnership (TÜ) the partners share liability, while a limited partnership (UÜ) needs at least one general partner with unlimited liability next to at least one limited partner. Both need two or more founders and no minimum capital. They are rare in practice because the OÜ gives the same flexibility with a liability shield.
Share Capital Rules for an Estonian OÜ
Minimum share capital
The old €2,500 minimum for a private limited company was abolished in 2023, and e-Residency now cites a minimum of €0.01 per shareholder. Some guides online still quote €2,500, so check the date on any source you rely on.
Contributions and unpaid shares
Contributions can be monetary or in kind. Until a shareholder has fully paid the agreed contribution, the shareholder remains liable to the company for the unpaid amount. A tiny share capital is therefore legal, but banks, investors and counterparties often read it as a sign of how much the owners are prepared to put behind the company.
Capital for an AS
An AS needs at least €25,000 in share capital. A company that cannot justify that figure and does not need a supervisory board is generally better placed as an OÜ. The wider requirements around address, contact person and capital are explained in Estonia company requirements: contact person, address and capital.
Liability in Each Legal Form
Shareholders in an OÜ or AS
In both limited companies the shareholder risks the money invested and any unpaid contribution, not personal assets. The company is the party that owes its debts.
Sole proprietors and partners
A FIE is not a legal person, so the owner and the business are the same person for legal purposes. General partners in a UÜ carry unlimited liability, and TÜ partners share liability.
Branches
A branch's liabilities sit with the foreign company that opened it, which makes the parent's own financial position relevant to anyone dealing with the branch.
When Does an Estonia Holding Company Make Sense?
How a holding OÜ is taxed
Since 2025 Estonian dividends are taxed only at the company level at 22/78 of the net distribution, according to the Tax and Customs Board. Profit that stays in the company is not taxed in Estonia. This deferral is what makes an Estonian holding company attractive: profits and gains can be reinvested inside the group without a tax charge until a distribution is made.
Dividends from an Estonian subsidiary that has already paid tax on the distribution go to a resident company holding at least 10% with no withholding and no final tax for the recipient. Dividends from foreign subsidiaries with a holding of at least 10% are generally exempt, subject to conditions, for example that foreign tax was paid or withheld. The basics of the system are in Estonia corporate tax explained.
Example of a holding structure
For example, a founder of two Estonian software OÜs could set up a third OÜ that owns 100% of both. Each operating company pays its dividend up to the holding OÜ, which keeps the cash and funds a new project without paying a further layer of tax. Tax arises when the holding OÜ finally pays a dividend to its own owner. A sensible check before doing this is whether the founder plans to take money out regularly, because in that case the holding adds an entity and accounting without much deferral benefit.
When a holding OÜ adds little
A single operating company with one owner who draws profit every year rarely needs a separate holding. A holding also needs its own board member, address and annual report, so it makes the most sense for groups with several operating companies, stakes in foreign subsidiaries or planned exits.
How to Choose a Legal Form in Estonia
Questions to ask first
Most founders settle the question by checking four things: whether they are based abroad, whether outside investors will join, whether the business will hold other companies, and whether anyone needs a liability shield. A non-resident founder without an Estonian base is practically limited to an OÜ, an AS or a branch, and the OÜ is the one with the lowest requirements.
Registration route and state fee
The OÜ is registered in the Company Registration Portal of the Centre of Registers and Information Systems (RIK), and the e-Residency pages list a €265 state fee for online registration and €25 for later amendments. After registration, a business account is the next practical step, covered in open a business bank account in Estonia as a non-resident.
FAQ on Estonian Company Forms
Can a non-resident open a sole proprietorship in Estonia?
The e-Residency site says FIEs must be situated in Estonia and are therefore not typically available to e-residents. A non-resident who wants to trade in Estonia usually forms an OÜ or registers a branch of an existing foreign company.
Is an OÜ the same as an LLC?
Both limit the owners' liability, but an OÜ is governed by the Estonian Commercial Code and has its own rules on share capital, management board and dividend taxation. A US LLC is a different instrument under state law, and tax treatment on both sides should be checked before the two are combined in one structure.
What is the minimum share capital for an Estonian OÜ?
The e-Residency program gives the minimum as €0.01 per shareholder. An AS, by comparison, needs €25,000. Larger capital is still common where a bank or a business partner expects visible funding.
Final Thoughts
For most founders the Estonian OÜ is the practical default: shareholder liability is limited, share capital can start at €0.01, registration is online, and the state fee quoted by e-Residency is €265. An AS is for companies that need a supervisory board and €25,000 of capital, a FIE is generally unavailable to non-residents, and a branch keeps the parent liable. A holding OÜ becomes useful once profits from several companies are reinvested rather than paid out each year.
Before incorporating, confirm the current tax treatment of any foreign dividends and the share capital wording in the Commercial Code. Inter Lawyers can help you compare these forms for your own structure and prepare the registration of the right Estonian entity.
