Estonian Company Run from Oman: Tax Rules

Some entrepreneurs who live in Oman form or buy an Estonian private limited company (OÜ), often as e-residents, and run it from Muscat. Oman's income tax is charged on Omani companies — companies established under Omani law — and on permanent establishments in Oman, and a place of management is a permanent establishment. Separately, a legal person whose main or effective headquarters is in Oman counts as an Omani tax resident. Oman has no rule on controlled foreign companies. The Estonia–Oman tax treaty, in force since November 2025, leaves a company resident in both countries to an agreement between the two tax authorities. 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 Omani tax adviser before you form or buy the company. We read the Income Tax Law promulgated by Royal Decree 28/2009 in the consolidated text as amended by Royal Decree 118/2020, in the English translation published by the Oman Tax Authority (the Arabic text prevails), and the Estonia–Oman tax treaty in Riigi Teataja, on 24 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 Oman: the company side

Who pays the tax. A taxpayer is an enterprise, an establishment, an Omani company or a permanent establishment; an Omani company is any person established in Oman as a company under the legislation of Oman (Income Tax Law, Article 1). Tax is charged on the taxable income accruing to a taxpayer for the tax year (Article 39).
Permanent establishment. A permanent establishment is a fixed place of business through which a business is wholly or partly carried on in Oman by a foreign person; it includes especially a place of management, a branch and an office, and also a foreign person providing consultancy or other services in Oman for not less than ninety days in any twelve months (Article 2).
Tax residence. A legal person is resident in Oman in a tax year if it is incorporated in Oman or if its main or effective headquarters is in Oman (Article 18bis). A non-resident without a permanent establishment is taxed by deduction at source on certain Omani income, such as royalties and fees for services (Articles 40 and 52).
Rate. Tax is 15% of the taxable income of an establishment, an Omani company or a permanent establishment (Article 112); the tax deducted at source from a non-resident is 10% of the gross amount (Article 113).

An Estonian OÜ is not an Omani company. If you run it from Muscat, the place where it is managed can be a permanent establishment in Oman, and its main or effective headquarters can make it an Omani tax resident. Your Omani tax adviser answers that with the facts of your case.

In Oman: the owner side

Who is a resident individual. A natural person present in Oman for not less than 183 days, continuous or intermittent, in the tax year is resident (Article 18bis).
No controlled foreign company rule. The law as we read it has no rule that adds a foreign company's retained profit to its owner's income.

How an owner living in Oman is taxed on what the Estonian company pays out is a question for your Omani tax adviser.

What the Estonia–Oman tax treaty says

Resident in both countries. If a person other than an individual is resident in both states, the competent authorities endeavour to determine by mutual agreement of which state it is a resident, having regard to its place of effective management, the place where it is incorporated and any other relevant factors; without such an agreement it is not entitled to any relief or exemption under the treaty except as the authorities agree (agreement signed in Muscat on 27 October 2024, article 4(3); RT II, 05.11.2025, 2).
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 Omani resident receives as a member of the board of directors or a similar body 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 Omani resident may be taxed in Oman; if Estonia also taxes them at source, the treaty limits that tax to zero per cent of the gross amount for a company holding directly at least twenty per cent of the capital, and ten per cent in all other cases (article 10(1) and (2)).
From when. On the Estonian Ministry of Finance's list, the agreement entered into force on 24 November 2025 and applies from 1 January 2026.

So the treaty does not settle a double residence by itself: a company with its effective headquarters in Oman 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 Omani tax adviser — we do not give that ruling.

What to decide before you form or buy the company

Where the company is managed. A place of management in Oman is a permanent establishment, and a main or effective headquarters there makes the company an Omani tax resident.
Where the work is done. Services provided in Oman for ninety days or more in twelve months make a permanent establishment.
How profits reach you. Dividends and board fees are covered by articles 10 and 16 of the treaty.

Frequently asked questions

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

It can be. Oman charges tax on Omani companies and on permanent establishments, and a place of management in Oman is a permanent establishment (Income Tax Law, Articles 1, 2 and 39), at 15% (Article 112); a legal person with its main or effective headquarters in Oman is also an Omani tax resident (Article 18bis). In Estonia the company stays resident because it was established under Estonian law (Income Tax Act § 6). Under the Estonia–Oman tax treaty the competent authorities try to decide such a double residence by agreement; without one the company gets no treaty relief (article 4(3)). Oman has no controlled foreign company rule. Ask an Omani tax adviser before you form or buy the company; we handle the Estonian side.
