Estonian Company Run from Switzerland: Tax Residence

Many Swiss entrepreneurs form or buy an Estonian private limited company (OÜ), often as e-residents, and run it from Switzerland. That works, but Swiss tax law does not look only at where a company is registered: a legal person whose effective management (tatsächliche Verwaltung) is in Switzerland is taxable there without limit. The tax treaty between Estonia and Switzerland leaves a company resident in both countries to the two tax administrations. This guide sets out these rules with the official texts, and what we do on the Estonian side.

The guide is general information, not tax advice. How your company and you are taxed depends on the facts of your case; ask a Swiss tax adviser before you form or buy the company. We read the Federal Act on Direct Federal Tax (Bundesgesetz über die direkte Bundessteuer, DBG) in its version of 2 September 2026 on the federal law platform Fedlex, and the treaty and its amending protocol in their Estonian texts in Riigi Teataja, on 21 October 2026; the English wording below is our translation. Cantonal and communal taxes follow cantonal law and are not covered.

In Estonia: an Estonian company is Estonian

A company established under Estonian law is resident in Estonia for tax purposes (Income Tax Act § 6). Its profit is taxed when it is distributed, not while it stays in the company — the guide how Estonia taxes company profit explains the rule. The company keeps its Estonian duties wherever its owners live: accounts, an annual report to the commercial register and, if its address is abroad, a contact person in Estonia.

In Switzerland: seat or effective management

Personal attachment. Legal persons are taxable on the basis of personal attachment if their seat or their effective management is in Switzerland (DBG, Art. 50).
Foreign companies included. Foreign legal persons are treated like the Swiss legal persons they most resemble in law or in fact (Art. 49(3)) — for an OÜ, a limited liability company.
Unlimited liability. With personal attachment the tax liability is unlimited; it does not extend to businesses, permanent establishments and real estate abroad (Art. 52(1)). The federal profit tax of companies is 8.5 percent of net profit (Art. 68).

What the Estonia–Switzerland tax treaty says

Resident in both countries. If a person other than an individual is resident in both states, the competent authorities settle the question by agreement (agreement signed in Bern on 11 June 2002, article 4(3), as replaced by the protocol signed in Tallinn on 25 August 2014, in force since 15 October 2015). The treaty does not decide it by itself.
A future change. The treaty's protocol provides that as soon as both states have introduced the place of effective management as a criterion of residence in their laws, article 4(3) will give a company the residence of the state where its effective management is. Estonia's Income Tax Act defines a resident legal person by its establishment under Estonian law (§ 6).
Permanent establishment. A permanent establishment is a fixed place of business through which the business of an enterprise is wholly or partly carried on; it includes especially a place of management, a branch and an office (article 5(1) and (2)). The profit attributable to it may be taxed in the state where it is (article 7(1)).
Directors' fees. Fees a Swiss resident receives as a member of the board or a similar organ of an Estonian company may be taxed in Estonia (article 16) — see board member fee or dividend from abroad.
Dividends. Dividends paid by an Estonian company to a Swiss resident may be taxed in Switzerland; if Estonia also taxes them at source, the tax may not exceed 10 percent of the gross amount, and none is due on a dividend to a company holding directly at least 10 percent for at least one year before the payment (article 10(1) to (3), as replaced by the 2014 protocol).

So, as with the United Kingdom, Turkey, Austria and Ireland, the treaty does not settle a double residence by itself: a company whose effective management is in Switzerland may need an agreement between the two tax administrations. The multilateral convention on tax treaty measures (MLI) can change the rules of tax treaties; how it applies to your company is a question for your Swiss tax adviser — we do not give that ruling.

A controlled foreign company rule?

In the Federal Act on Direct Federal Tax we found no rule that adds the undistributed profit of a foreign company to the income of its Swiss owner. We did not read cantonal law. Whether the profit of the Estonian company reaches you in another way — through the residence rule above or through a permanent establishment — is a question for your Swiss tax adviser.

What to decide before you form or buy the company

Where the company is effectively managed. Where the decisions that direct the company are in fact taken is the fact the Swiss rule looks at.
Where the work is done. An office or other fixed place of business in Switzerland can be a permanent establishment.
Who holds the shares. The treaty's dividend rules differ for a company holding at least 10 percent and for other owners.

Frequently asked questions

Is my Estonian company taxed in Switzerland if I run it from Switzerland?

It can be. Legal persons whose seat or effective management is in Switzerland are taxable there on the basis of personal attachment, and foreign legal persons are treated like the Swiss ones they most resemble (Federal Act on Direct Federal Tax, Art. 49(3) and 50). In Estonia the company stays resident because it was established under Estonian law (Income Tax Act § 6). Under the Estonia–Switzerland tax treaty the competent authorities settle such a double residence by agreement (article 4(3), as replaced by the 2014 protocol). Ask a Swiss tax adviser before you form or buy the company; we handle the Estonian side.
