Offshore Company for UK Residents: Tax and Practical Limits

If you live in the United Kingdom and are looking at an offshore company in Mauritius, the first question is not "how do I form it" but "where will it be managed". For a UK resident who sits in a UK home office, signs contracts from there and takes the decisions, the answer is usually the UK, and that single fact drives most of the tax outcome. This page sets out why, and where an Authorised Company can still make sense.

It is general information, not advice. Whether the structure works depends on your own residence, your work and your clients, and it should be tested by a UK-qualified adviser before you commit.

Why a UK-managed company stays taxable in the UK

Mauritius and the UK each decide residence for a company with their own tests, and a company can be caught by both. What matters here is the idea of central management and control: the place where the real decisions of the company are taken.

On the Mauritian side, the Income Tax Act treats a company as resident if it is incorporated in Mauritius or if its central management and control sit there (section 73). Section 73A then covers the opposite case: a Mauritian-incorporated company that is centrally managed and controlled outside Mauritius is treated as non-resident, although it must still file an income tax return under section 116.

An Authorised Company is built for that second situation. By law its central management and control must be outside Mauritius, and it must have a Mauritian registered agent, which is a FSC-licensed corporate service provider (Management Licence). You can read the mechanics on the page about managing an Authorised Company from abroad.

The consequence for a UK resident is direct. If you are the sole director and every meaningful decision is taken from your kitchen table in England, the company is managed from the UK. A Mauritian certificate of incorporation does not change where the decisions are made. HMRC looks at facts, not at the country on the registration papers, so a company run from the UK can be treated as UK resident for corporation tax purposes, with its worldwide profits in scope.

What the Mauritian side does not do for you

• It does not make the company a Mauritian tax resident. An Authorised Company is non-resident by design.
• It does not give access to Mauritius's double taxation agreements. See the limits of an Authorised Company.
• It does not remove your own personal exposure as a UK resident, for example on money you take out of the company. That is covered under how the owner is taxed at home.

What the UK adds on top

Beyond company residence, several UK concepts can apply to a UK-resident owner of a foreign company. Each depends on facts and is outside the scope of Mauritian law:

• Permanent establishment. Even if the company were treated as foreign, a UK-based director doing the work can create a taxable presence in the UK. The page on permanent establishment risk explains the principle.
• Controlled foreign company rules. UK rules can attribute certain profits of a low-taxed foreign company to UK-resident owners. The general mechanism is set out in the guide to CFC rules; this page does not repeat it.
• Personal taxation of what you extract. Salary, dividends or loans from the company are assessed on you personally in the UK.
• Transparency expectations. Mauritian companies must identify and record their beneficial owner on a permanent basis, with full name, residential address, national identity or passport number, nationality and the holding structure (Companies Act 2001, section 91(3A)). A UK resident should assume that information is available to authorities and to banks. See ownership privacy.

Can an Authorised Company ever work for a UK resident?

Yes, in a narrower range of situations than most marketing suggests. The structure is more coherent when the real management genuinely sits outside both Mauritius and the UK, or when the UK resident is not the controlling mind of the company.

A word on the Mauritian individual residence tests, since they come up for people who relocate: a person is resident in Mauritius if domiciled there (unless permanently resident abroad), or if present for 183 days or more in the income year, or for 270 days or more across that year and the two preceding years (section 73 of the Income Tax Act). Those tests concern individuals; they say nothing about where a company is managed.

A quick decision path

The tree below is a simplification to help you frame the conversation with an adviser. It is not a determination of anyone's tax position.

Practical limits to check before going further

The activity must be permitted

An Authorised Company cannot carry on the activities listed in the Fourth Schedule of the Financial Services Act. Read what business an Authorised Company can run before you plan around it. Crypto and regulated financial services are the usual stumbling blocks.

Banking is harder when the owner is in the UK

Banks and payment providers ask where the owner lives and where the work is done. A UK-resident owner with a company whose only link to Mauritius is its registered agent often meets questions, delays or refusals. The reasons are discussed in why banks refuse offshore company accounts and the banking options.

Clients and suppliers notice

Some UK clients, platforms and suppliers treat an offshore counterparty differently. Perception and onboarding checks are covered in how clients perceive an offshore company.

Filing and fees still apply

Even a non-resident Authorised Company files an income tax return in Mauritius, because section 116 requires every company to do so, taxable or not. The registered agent handles filings and communications with the FSC, the MRA and the Registrar, as well as anti-money-laundering measures and record keeping (section 71A(8) of the Financial Services Act). Annual regulator fees are paid through the FSC One platform; for the 2026-27 cycle the FSC extended the payment deadline to 30 September 2026. Those costs run alongside, not instead of, any UK compliance. See annual obligations.

Fee changes reflect risk profile

In a communiqué of 10 July 2026 the FSC said processing fees had not changed since the 2008 rules and that annual fees had not been reviewed since 2019, and it justified the adjustment of Authorised Company fees by their inherently higher risk profile. A UK resident should therefore budget for a structure that regulators regard as higher risk, not as a routine product.

Where the Mauritian side is straightforward

Not everything is unfavourable. A few Mauritian points are worth knowing, as long as they are read in context:

• The Income Tax Act defines a "global business entity" to include both a Global Business Licence holder and an Authorised Company. The Alternative Minimum Tax of section 44A does not apply to a global business entity.
• The FSC may grant an Authorised Company authorisation within 10 working days of the application being considered complete, for applications filed from 1 October 2024 (section 17B and 17C of the Financial Services Act).
• A Tax Residence Certificate can be requested from the MRA Director-General by a person wishing to be certified resident in Mauritius, but an Authorised Company is non-resident by design, so this is not a tool for that structure.

None of these changes the UK analysis. The Mauritian tax treatment of the company is covered on the taxation page, and the Global Business Licence route, which requires management from Mauritius, is dealt with elsewhere.

Questions to settle before you proceed

• Where will each decision actually be taken, and by whom?
• Is that location outside the UK in substance, not only on paper?
• Is the activity allowed for an Authorised Company?
• Which UK rules apply to you personally on extraction of profits?
• Can the company open an account given your residence?
