Self-Check: Is Your Offshore Structure Exposed to Tax Risk?

Most tax problems in an offshore structure do not come from the company itself. They come from the gap between what the paperwork says and what actually happens: who decides, where they sit, where the customers are and which returns were filed. An offshore company tax risk checklist is a way to look at that gap calmly, one question at a time, before a bank, a tax office or a counterparty does it for you.

This page is a self-audit tool for the owner of an Authorised Company. It does not replace advice: the answers depend on your country of residence, your activity and your contracts, and a few "yes" answers below are a reason to speak to a qualified adviser, not a conclusion.

How to use this self-check

Take the structure as it is today, not as it was designed. Have the constitution, the latest filed return, bank statements and a list of who signed what over the past year within reach. Then go through four areas in order:

1. Place of management: where the real decisions are taken.
2. Substance and activity: whether what the company does is allowed and coherent.
3. Cash flows: how money enters, moves and leaves.
4. Filings and records: what has been submitted and what can be produced on request.

Two topics are deliberately left to their own pages: controlled foreign company rules and permanent establishment risk. The checks below only tell you when it is worth reading them.

The decision tree: four questions to run first

The tree below is a quick filter. It does not produce a verdict; it tells you which section to read next.

1. Place of management

Why it comes first

Under the Income Tax Act, a company is tax resident in Mauritius if it is incorporated there or if its central management and control is there (section 73(1)(b)). Section 73A then provides that a company incorporated in Mauritius is treated as non-resident when it is centrally managed and controlled outside Mauritius, and that it must still file an income tax return under section 116.

Two consequences follow. First, "managed from abroad" is a factual claim you may have to prove. Second, the company is not exempt from filing simply because it is non-resident. The practical side of this is covered in managing an Authorised Company from abroad.

Signals to check

• Board decisions are actually taken by the directors, in the place the records say they were taken
• Minutes and resolutions are dated, signed and consistent with travel and work patterns
• Contracts with clients and suppliers are signed by someone with a documented authority
• The people who run the day-to-day business are identified, with their country of residence
• A power of attorney, if one exists, is limited in scope and recorded
• Nobody outside the board gives instructions that the board simply signs off

Warning sign: the paperwork shows meetings in one place while the owner's calendar, e-mails and flights point to another. Inconsistency is more damaging than either location taken alone.

Your home country is a separate question

Everything above concerns Mauritius. Your own country of residence applies its own tests, and may look at where you live and work regardless of the company's status. How the owner is taxed at home sets out the logic; the answer is specific to your jurisdiction.

2. Substance and activity

Is the activity allowed?

Unless the FSC Rules provide an exception, an Authorised Company cannot carry on the Fourth Schedule activities of the Financial Services Act. There are five categories:

• banking;
• managing or administering a collective investment fund or scheme as a professional;
• financial services;
• corporate services for companies, such as head office, nominee, director or secretarial services;
• professional trusteeship.

If your real activity touches one of these, the issue is not tax risk but the legal basis of the structure. See what business an Authorised Company can run and its limits.

Does the activity match the structure?

• The activity described in the constitution and on the bank file is the one actually carried on
• You can explain in two sentences why the company, rather than you personally, earns the income
• Any employees or contractors are engaged under contracts that name the right entity
• Equipment, software and intellectual property used in the business are held by the entity that claims the income
• There is no income that obviously belongs to another entity in your group or to you personally

A related point: Mauritius reliefs that depend on substance, such as the partial exemptions on certain foreign dividends or interest, are conditioned on meeting the prescribed substance requirements. Do not assume a partial exemption applies to your company; read the conditions and confirm them with your adviser before relying on one.

3. Cash flows

Money tells the story the contracts leave out. Trace one month of activity from the customer to your personal account.

Inbound

• Customers pay the company, never you personally
• Invoices carry the company's details and match the bank account that receives the funds (see invoicing clients from an offshore company)
• Payment processors are registered in the company's name, not in a personal name
• You know whether any payer withholds tax at source (see withholding tax on payments received)

Outbound

• Every payment to you is documented as a salary, fee, dividend or loan, with an agreement or a resolution behind it
• Personal expenses are not paid from the company account
• Payments to contractors have contracts, invoices and a clear business purpose

Paying yourself is a topic of its own: dividends from an offshore company explains the routes and their trade-offs.

Red flags in the bank file

Banks run their own checks, and a refusal or an account review often signals a mismatch between the stated profile and the flows. Why banks refuse offshore company accounts lists the typical causes.

4. Filings and records

Annual tax return

Every company, taxable or not, must file its income tax return with the Director-General within 6 months after the end of the month in which its financial year closes (section 116(1) Income Tax Act). For a year ending in June, the deadline is 2 working days before the end of December; for a year ending in December, it is 2 working days before the end of June. Filing and payment are made electronically.

The standard corporate rate in Mauritius is 15% of chargeable income, under the First Schedule, Part IV of the Income Tax Act. Whether and how that rate applies to a given Authorised Company, and which partial exemptions it may claim, is for your adviser to confirm. Taxation of an Authorised Company gives the framework.

Other levies to check against your figures

• Corporate Climate Responsibility Levy: 2% of chargeable income of any company for tax years starting on or after 1 July 2024 (section 50O). No levy is due when turnover for the tax year does not exceed MUR 50 million. Since the Finance Act 2026, companies in the APS system pay it in three instalments of 25% with their APS returns and the balance with the annual return; others pay it with the annual return.
• Alternative Minimum Tax: 10% of adjusted book profit where normal tax is lower (section 44A), from the tax year starting on 1 July 2026. It does not apply to a global business entity, a term that covers both a Global Business Licence holder and an Authorised Company.
• Foreign tax credit: section 77 gives credit for foreign tax paid on foreign income against Mauritius tax on the same income, but no credit where a Part II Second Schedule partial exemption has been claimed on that income.

If your accountant has never mentioned any of these, ask whether they were considered and why they do or do not apply.

Annual fees and the registered agent

The annual FSC fee for an Authorised Company is USD 1,400 under the schedule in force since 1 July 2026. It rises to USD 1,750 if paid within one month after the due date, USD 2,100 between 1 and 3 months late, and USD 2,800 between 3 and 6 months late. For the 2026-27 cycle, the FSC moved the payment deadline to 30 September 2026. A missed fee is an easy-to-avoid exposure; see annual fees.

The registered agent of an Authorised Company is responsible, among other things, for filing the returns and documents required under the Financial Services Act, the Income Tax Act or the Companies Act, relaying communications with the FSC, the MRA and the Registrar, AML/CFT measures and keeping the company's records, including minutes, resolutions and transaction documents (section 71A(8) FSA). Ask your FSC-licensed corporate service provider (Management Licence) in writing what it files for you and what remains your job. The questions to ask a provider help structure that conversation.

Beneficial ownership

Every Mauritian company must at all times identify its beneficial owner and any nominee, and record them in a separate register: full name and residential address, national identity or passport number, nationality, and the holding structure that identifies the ultimate beneficial owner (Companies Act 2001, section 91(3A)). The Registrar of Companies keeps a Beneficial Ownership Register accessible to competent authorities and other prescribed public authorities; the Companies Act does not describe it as public. See ownership privacy for what that means in practice.

Tax Residence Certificate

If you need to prove Mauritius residence, for instance to a foreign payer, apply to the Director-General for a Tax Residence Certificate. It must be issued within 7 days of the application, provided the required return (section 112 or 116) has been filed and the fee paid. For a company, the fee under the Income Tax Regulations 1996 is USD 200 in cases other than a CIS. A certificate says something about Mauritius status; it does not by itself settle your tax position elsewhere.

Records you should be able to produce

• Accounting records and financial statements for each year (see accounting records)
• Filed income tax returns with proof of electronic submission
• Proof of payment of the annual FSC fee
• Minutes and resolutions for the year
• Beneficial ownership register up to date
• Contracts and invoices supporting each income stream

Scoring your answers

Count the unticked boxes in each section. There is no pass mark, but the pattern is informative.

What a good fix looks like

Fixing exposure means aligning reality and paper, not decorating one to hide the other. In practice, that means moving real decisions to where the records say they are made, or changing the records to say what is true; moving payments onto proper contracts; and filing on time. If the honest answer is that the structure no longer fits your life or business, when an Authorised Company is no longer enough covers the alternatives.

If you want a provider to look at your structure, you can send a request through the contact form; the information you share is relayed to an FSC-licensed firm, which can discuss your situation and will give you a view specific to it.
