Many British entrepreneurs form or buy an Estonian private limited company (OÜ), often as e-residents, and run it from the United Kingdom. That works, but UK tax law does not look only at where a company is incorporated: a company incorporated abroad can be UK resident if its central management and control is in the UK. The tax treaty between Estonia and the United Kingdom has its own rule for a company that both countries count as resident. This guide sets out both, with the official texts, and what we do on the Estonian side. If you are comparing an Estonian OÜ with a UK limited company in the first place, see Estonian company vs UK Ltd.
The guide is general information, not tax advice. How your company is taxed depends on the facts of your case; ask a UK tax adviser before you form or buy the company. The Corporation Tax Act 2009 was read on legislation.gov.uk, HMRC's International Manual on GOV.UK, and the treaty in the English text published in Riigi Teataja, on 21 October 2026.
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 the United Kingdom: central management and control
- Incorporation is not the only test. A company incorporated in the UK is UK resident (Corporation Tax Act 2009, section 14). For a company incorporated abroad, such as an OÜ, residence follows the case-law rule that HMRC describes in its International Manual (INTM120060): a company resides where its central management and control actually abides — in the words of the leading case, De Beers Consolidated Mines Ltd v Howe, where its real business is carried on.
- Why it matters. A UK resident company is chargeable to corporation tax on all its profits wherever arising (section 5(1)). A company that is not UK resident is within the charge only in limited cases — among them, when it carries on a trade in the UK through a permanent establishment there (section 5(2) and (3)).
- The treaty can override. A company treated as resident outside the UK for the purposes of a double taxation agreement is non-UK resident for the Corporation Tax Acts, even if it would otherwise be UK resident (section 18).
What the Estonia–United Kingdom tax treaty says
- Resident in both countries. If a company is resident in both states under the treaty's definition, the competent authorities of the two states shall endeavour to settle the question by mutual agreement; without such agreement, the company is not entitled to any relief or exemption from tax under the treaty (convention signed in London on 12 May 1994, article 4(3), in the text published in Riigi Teataja).
- Permanent establishment. A permanent establishment is a fixed place of business through which the enterprise's business 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)).
- Director's fees. Fees a UK resident receives as a board member 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 UK resident may be taxed in the UK; if Estonia also taxes them at source, the treaty limits that tax to 5 percent for a company controlling at least 25 percent of the voting power and 15 percent in other cases (article 10(1) and (2)).
So, unlike some other treaties, this one does not settle a double residence automatically: a company whose board in fact directs it from the UK may need a mutual agreement before it can rely on the treaty at all. 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 UK tax adviser — we do not give that ruling.
What to decide before you form or buy the company
- Where the board really decides. Where the directors take the decisions of real importance — not only where they formally meet — is the fact HMRC looks at.
- Who sits on the board. If the only director lives in the UK and takes the decisions there, that is a fact HMRC weighs under the same test.
- Where the work is done. An office or other fixed place of business in the UK can be a permanent establishment.

Frequently asked questions
Is my Estonian company taxed in the UK if I run it from the UK?
It can be. A company incorporated abroad is UK resident if its central management and control is in the UK — where the decisions of real importance are actually taken (HMRC International Manual INTM120060) — and a UK resident company is chargeable to corporation tax on all its profits (Corporation Tax Act 2009, section 5(1)). In Estonia the company stays resident because it was established under Estonian law (Income Tax Act § 6). Under the UK–Estonia tax treaty the two tax administrations try to settle such a double residence by mutual agreement, and without an agreement the company gets no relief under the treaty (article 4(3)). Ask a UK tax adviser before you form or buy the company; we handle the Estonian side.
