Estonian Company Run from Ireland: Tax Residence

Many Irish entrepreneurs form or buy an Estonian private limited company (OÜ), often as e-residents, and run it from Ireland. That works, but Irish tax law does not look only at where a company is registered: a company incorporated abroad that is centrally managed and controlled in Ireland is resident in Ireland for tax purposes. The tax treaty between Estonia and Ireland leaves a company resident in both countries to the two tax administrations. Ireland's controlled foreign company (CFC) rules, on the other hand, are written for Irish companies that control a foreign one. 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 an Irish tax adviser before you form or buy the company. We read the Irish Revenue Commissioners' Tax and Duty Manual Part 02-02-03 "Company Residence in the State" (last reviewed May 2026) and Part 35B-01-01 "Controlled Foreign Company Rules" (last updated January 2025), which explain the Taxes Consolidation Act 1997, and the treaty in its Estonian text in Riigi Teataja, on 21 October 2026; the English wording below is our translation.

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 Ireland: central management and control

Irish companies by incorporation. Since Finance Act 2014, a company incorporated in Ireland is resident in Ireland unless a tax treaty treats it as resident elsewhere (Taxes Consolidation Act 1997, section 23A, as Revenue's manual Part 02-02-03 explains it). An Estonian OÜ is not incorporated in Ireland.
Foreign companies by management. Revenue writes that a company incorporated in a foreign jurisdiction and centrally managed and controlled in Ireland is resident in Ireland for tax purposes; the common-law rule of central management and control continues to apply to such companies (Tax and Duty Manual Part 02-02-03, part 2).
What decides. Central management and control is a question of fact. Revenue lists where the important questions of company policy are determined, where the majority of directors reside, where major contracts are negotiated, where the board meets and where the head office is — the highest level of control, not day-to-day business (part 5).
What a resident pays tax on. A company resident in Ireland is liable to corporation tax on its worldwide profits; a non-resident company is within the charge only if it carries on a trade in Ireland through a branch or agency (part 1).

What the Estonia–Ireland tax treaty says

Resident in both countries. If a person other than an individual is resident in both states, the competent authorities try to settle the question by mutual agreement; without such an agreement the person is not entitled to the treaty's benefits (agreement signed in Dublin on 16 December 1997, article 4(3); RT II 1998, 33, 62).
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 an Irish 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 an Irish resident may be taxed in Ireland; if Estonia also taxes them at source, the treaty limits that tax to 5 percent of the gross amount for a company (other than a partnership) holding directly at least 25 percent of the voting power, and 15 percent in all other cases (article 10(1) and (2)).

So, as with the United Kingdom, Turkey and Austria, the treaty does not settle a double residence by itself: a company whose central management and control is in Ireland may need an agreement between the two tax administrations before it can rely on the treaty. 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 Irish tax adviser — we do not give that ruling.

In Ireland: the CFC rules

For an Irish company as owner. A CFC is a non-resident company controlled by a company or companies resident in Ireland; the CFC charge can only arise to companies (Taxes Consolidation Act 1997, sections 835I and 835J, as Revenue's manual Part 35B-01-01 explains them). An Irish-resident individual who owns the Estonian company is not charged under these rules.
When it applies. The rules attribute undistributed income that arises from non-genuine arrangements put in place for the essential purpose of avoiding tax, where the controlling company or a connected company carries out the significant people functions in Ireland; control means, broadly, more than 50% of the share capital, voting power or distributions (Part 35B-01-01, introduction).

Whether the rules reach you depends on who owns the Estonian company — you yourself or an Irish company of yours — and on where the work behind its income is done; your Irish tax adviser answers that with your figures.

What to decide before you form or buy the company

Where the board really decides. Where company policy and major decisions are in fact settled is the fact the Irish rule looks at.
Who owns it. The CFC rules speak of an Irish company as owner; owning the OÜ through an Irish company changes the analysis.
Where the work is done. An office or other fixed place of business in Ireland can be a permanent establishment.

Frequently asked questions

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

It can be. Ireland's Revenue writes that a company incorporated abroad and centrally managed and controlled in Ireland is resident in Ireland for tax purposes, and a company resident in Ireland is liable to corporation tax on its worldwide profits (Tax and Duty Manual Part 02-02-03). In Estonia the company stays resident because it was established under Estonian law (Income Tax Act § 6). Under the Estonia–Ireland tax treaty the competent authorities try to settle such a double residence by agreement; without an agreement the company gets none of the treaty's benefits (article 4(3)). Ireland's controlled foreign company rules charge only an Irish company as owner. Ask an Irish tax adviser before you form or buy the company; we handle the Estonian side.
