A subsidiary and a branch can both get a foreign company legally present in Estonia within weeks. They are not, however, the same commitment. One creates a separate Estonian legal person with its own liability ceiling. The other extends your existing company into Estonia and extends its liability right along with it. Which one is right depends less on how ready you feel to "be in Estonia" and more on one concrete question: what, exactly, is the entity for? This article sets out the four dimensions that actually distinguish a subsidiary from a branch under Estonian law, and how to tell which one a specific situation is pointing to before you file anything.
Two ways to have a legal presence in Estonia, and they commit you to very different things
Under the Estonian Commercial Code, a subsidiary registered as an osaühing (OÜ) is a fully independent Estonian legal entity. It has its own board, its own share capital, its own registered address, and its own accounts. Its liability toward creditors and counterparties is limited to what has been invested in it. A branch (filiaal) is not a separate legal entity at all; it is the foreign company itself, operating in Estonia under a registered local presence. The Commercial Code is explicit on this point: the parent company is liable for the obligations arising from the branch's activities, without a cap.
That single distinction, separate legal person versus extension of the parent, is what drives almost every practical difference below: who's on the hook if something goes wrong, how the entity is taxed, what governance it needs, and how a bank or business partner reads it.
A subsidiary stands on its own. If it can't pay a debt, its creditors can pursue the subsidiary's assets, but not, ordinarily, the parent company's balance sheet beyond what was invested as capital. A branch offers no such separation. Every contract the branch signs, every debt it incurs, and every liability it creates is legally the parent company's, full stop.
This is the dimension that should carry the most weight for any company weighing the two structures, because it's the one that's hardest to undo after the fact. A subsidiary's capped liability is a structural feature of the entity from day one. A branch's uncapped exposure for the parent is equally structural, and no amount of good governance at the branch level changes it.
A subsidiary needs its own management board and registered address from the moment it's incorporated: standard requirements for any Estonian OÜ, regardless of who owns it. A branch works differently: the foreign company appoints one or more directors to manage the branch, and if fewer than half of those directors are resident in Estonia, another EEA state, or Switzerland, the company must additionally appoint an Estonian contact person.
In practice, a branch's governance is lighter to set up but stays permanently dependent on the parent's own decision-making: there's no independent board making calls locally, only a manager acting on the parent's behalf. A subsidiary's board can act, decide, and be held to account entirely within Estonia.
Both structures follow the same underlying Estonian principle: retained profit isn't taxed. Where they diverge is in what happens next. A subsidiary is its own Estonian corporate income taxpayer: it pays Estonian corporate income tax (22/78 in effect since 2025) only when it distributes profit, and it has its own independent tax and filing history that EMTA, banks, and partners can look up directly.
A branch's profit is taxed the same way, at the same rate, when it's paid out of the branch to the parent. But a branch has no independent tax identity of its own to point to; its position is inseparable from the foreign parent's, which is harder for an Estonian bank, supplier, or client to verify from the public record than a standalone Estonian company's filing history.
Estonian company data is public, and banks, payment institutions, and corporate counterparties routinely check it before doing business. A subsidiary reads as a standalone, capitalised, locally accountable entity. A branch reads as exactly what it is: an outpost of a foreign company, present but not independently committed.
The flip side is exit flexibility. A branch is materially cheaper and faster to unwind if a market test doesn't work out. Estonia's Business Register lists branch deletion as free, against real winding-up costs and procedure for a subsidiary. If the Estonian presence might not be permanent, that asymmetry is worth weighing on its own.
The real trigger isn't ambition, it's a named blocker
"We want a presence in Estonia" isn't, by itself, a reason to register either structure. What actually justifies committing to one is something specific and dated: a signed contract that requires an Estonian or EU counterparty, a licence that has to sit inside a locally registered entity, a first local hire. Those have names attached. General market interest doesn't, and it's usually better served by a distributor, a partner, or simply waiting until a real blocker appears.
| Signal | What it points to | Structure it suggests |
|---|---|---|
| A signed contract or client requires a locally registered, capitalised Estonian counterparty | Ongoing commitment where the other side needs to see standalone Estonian liability, not a foreign parent's | Subsidiary |
| You plan to hire employees, hold assets, or build a lasting Estonian team | A permanent presence where capped liability and independent credibility matter over time | Subsidiary |
| You have a specific, time-boxed contract or project and expect to wind down after it | Short-term presence where lower state fees and free-to-delete registration outweigh the liability trade-off | Branch |
| The parent is comfortable carrying full, uncapped liability for the Estonian activity | No need to isolate risk into a separately capitalised entity | Branch |
| You're testing demand with no named contract, licence, or hire yet | No blocker exists yet to justify either structure | Neither: wait, or use a local distributor/partner first |
"Which structure you need depends on what's already true about your business in Estonia (a contract, a licence, a hire), not on how ready you feel to formalise a presence there."
Lower state fees don't mean lower commitment
A branch's official state filing costs are genuinely lower than a subsidiary's: Estonia's Business Register lists roughly €12.75 for signature notarization, around €18.20 for application preparation, and €145 for registration, with processing in about five business days. That can read as the cheaper, faster option, and for the filing itself, it is.
What it doesn't do is reduce commitment. It moves the commitment from the entity onto the parent company's own balance sheet, and it adds an ongoing coordination requirement (a resident director or an appointed Estonian contact person) that has to be maintained for as long as the branch exists. 1Office Estonia's subsidiary registration for foreign entities, state fee, legal documentation, Power of Attorney representation, and Business Register submission, for €1,450 one-time plus €195/year from year two, is priced for the fuller commitment: a standalone entity with its own board, its own filing history, and liability capped at what's actually invested in it.
Describe the contract, licence, or hire behind your Estonian plans and we'll say plainly whether a subsidiary, a branch, or waiting is the right call.
A practical check before you register either structure
If nothing has a name and a date attached, neither structure is justified yet. A distributor or local partner can usually carry an exploratory stage without an entity at all.
This is the trade-off a branch's lower fees and faster registration don't remove. If the answer is no, that alone usually settles the question in favour of a subsidiary.
If fewer than half the branch's directors meet that residency threshold, an Estonian contact person is a legal requirement, not an option, and needs to be arranged before registration.
A subsidiary's standalone credibility depends on maintaining that independent filing history, not just on having incorporated it. This is where new subsidiaries most often stall a year or two in.
A branch's free deletion and lighter registration favour a presence with a foreseeable end. A subsidiary's capped liability and standalone credibility favour one that isn't going anywhere.
Neither structure is a default. A subsidiary and a branch answer different problems: a subsidiary isolates liability and builds standalone Estonian credibility for a presence that's meant to last; a branch gets a specific, time-boxed piece of work done in Estonia without separately capitalising an entity, at the cost of the parent carrying the liability directly.
Most companies that get this decision wrong don't get it wrong on the law. They get it wrong on timing: registering a subsidiary before a real blocker exists, or a branch when the presence was always going to be permanent. Both are avoidable with a plain read of what's actually driving the need for an Estonian entity right now.
1Office Estonia has formed more than 1,500 companies for over 20,000 clients, and handles subsidiary registration for foreign entities as a fixed-fee, fully represented service. Our formation conversation includes the honest version, including when the right answer is a branch, or waiting.
