Introduction to tax

1. Begin with the questions, not the percentage

Imagine that a colleague asks: “How much tax does a Mauritius company pay?” A percentage feels like an efficient answer. It is also incomplete. We do not yet know what the company earns, where it earns it, its residence, the period involved, or which exemptions and additional obligations apply.

A useful tax analysis begins with five questions:

1. Who is the taxpayer? A company, an individual, a trust and an associate in a société may follow different rules.
2. What is the taxable event or amount? Income tax examines income; VAT examines supplies and imports; registration duty may arise from a document or transaction.
3. Which jurisdiction has a connection? Residence and source are distinct. A foreign customer or a foreign bank account is not, by itself, a complete source analysis.
4. Which period and provision apply? A rule enacted this year can apply to an earlier period, start later, or require a further commencement step.
5. How is the obligation fulfilled? The person legally liable for a tax and the person required to deduct or remit it may differ.

These questions form your working file. The rate is one part of the file, not its opening and closing answer.

Legal starting points: Income Tax Act, sections 4–5, 73–74 and 111B–111C; VAT Act and its schedules. See the source register.

Residence is not the same as citizenship

A Mauritian citizen may have cross-border residence questions. A company incorporated in Mauritius requires a management-and-control analysis as well as an incorporation check. Section 73A treats a Mauritius-incorporated company as non-resident where it is centrally managed and controlled outside Mauritius.

A treaty can introduce another layer. Its definition of a resident and its rules for competing residence claims must be read separately. Do not assume that incorporation, a regulatory licence, or a certificate settles every condition in every treaty.

Source is not the route a payment takes

Suppose an invoice is paid in euros into a foreign bank account. Those are facts about currency and collection. They do not automatically establish that the underlying income has a foreign source. Ask what activity or asset produced the income and apply the statutory source rules.

The 2026 Finance Act illustrates why dates matter: section 7(l) adds a source rule for specified ICT services supplied in Mauritius. Older notes on offshore software payments must be read with that amendment.

2. A map of the legal framework

Tax law is a connected set of instruments. Open each part of the map to see the role it plays.

The practical reading order is: identify the relevant Act, inspect its current provision and schedules, follow its delegated conditions, then consider treaty and interpretive material where relevant. Record the date and the facts at every step. The Constitution and general legal principles provide the wider setting; this map is a research method, not a claim that every source has identical legal authority.

The principal families of law

Family	Principal instruments to locate	How they connect
Income and business profits	Income Tax Act 1995; Income Tax Regulations 1996; Foreign Tax Credit Regulations	Identify the taxpayer, compute income, apply relief and deal with foreign taxation.
Consumption	Value Added Tax Act; VAT Regulations; e-invoicing regulations	Analyse the supply or import, its classification, registration and collection.
Cross-border goods	Customs Act; Customs Tariff Act; Customs Regulations; origin regulations under trade agreements	Classification, value, origin and procedure determine the customs result. A trade agreement is not an income-tax treaty.
Excise	Excise Act; Excise Regulations; relevant valuation rules	Specific goods can attract excise in addition to other import or consumption charges.
Property and documents	Registration Duty Act; Land (Duties and Taxes) Act; Stamp Duty Act; Transcription and Mortgages Act	Identify the document, transfer, party and applicable relief rather than treating a property purchase as only an income-tax event.
Local rates	Local Government Act and relevant local instruments	A local property or rate obligation has its own statutory basis.
Employment and contributions	Social Contribution and Social Benefits Act; National Pensions Act; National Savings Fund Act; Human Resource Development Act; Workers’ Rights instruments	Distinguish PAYE from social contributions, levies and employment-law obligations.
Sector rules	Gambling Regulatory Authority Act; Freeport Act; Environment Act; relevant Civil Aviation and other sector provisions	A sector can add a charge, a collection duty, an exemption or an eligibility condition.
Administration and disputes	Mauritius Revenue Authority Act; tax-specific objection provisions; Revenue Tribunal Act 2025 and Rules 2026; Courts Act	Procedure, evidence, collection, objection and appeal are part of the analysis.
International cooperation	Tax treaties and protocols; MLI; CRS, country-by-country reporting and mutual-assistance instruments	Allocation of tax, relief, reporting and information exchange serve different purposes.
Amendments	Finance Acts and other amending Acts, including the 2026 fiscal measures	Amendments must be connected to the provision and its commencement rule.

The linked legislation inventory provides the individual Acts, regulations and historical references indexed for this trial. It also records what has only been indexed and what has been examined in these lessons. The inventory is broader than the short reading list above.

An important reading trap: the MRA directory marks certain instruments as “deleted” from its revenue-law list. That is not enough to conclude that the underlying Act has been repealed. For property duties, cross-check the Registrar-General’s sources and the actual legislation.

3. From income to liability

Keep these concepts separate:

• A deduction reduces the amount of income included in the calculation.
• An exemption removes a qualifying person or amount from a charge, subject to its conditions.
• A credit reduces computed tax, within the applicable limits.
• Withholding is a method of collecting tax from a payment. It does not tell you, by itself, whether the tax is final.

A small worked example

Assume a Mauritius-resident, ordinary company has revenue of Rs 1,000,000, allowable expenses of Rs 600,000, no other adjustments and no applicable exemption. Its illustrative chargeable income is Rs 400,000. At the ordinary corporate rate of 15%, its income tax before credits is Rs 60,000.

This example isolates corporate income tax. It does not determine CSR, VAT, payroll obligations, minimum top-up tax, or any other contribution. It also assumes that the expenses really are allowable; accounting recognition does not establish tax deductibility.

Now suppose that, instead, the relevant amount were a qualifying foreign dividend eligible for an 80% partial exemption. The arithmetic “15% × 20% = 3%” describes the income tax on that qualifying base under those assumptions. It does not turn “3%” into a universal rate for every GBC or every foreign receipt.

Income Tax Act, First Schedule Part IV and Second Schedule Part II, Sub-part B item 6; Income Tax Regulations, regulation 23D.

Go deeper: why expenses can change an exemption example

If part of an income stream is exempt, you must also investigate the treatment of expenditure incurred to produce that income. A calculation that exempts most of the receipt but deducts every related expense can overstate relief. Regulation 8 addresses expenditure attributable to exempt income. Read its wording and exceptions alongside the relevant exemption.

For foreign-tax credit, establish the foreign-source income and the Mauritius tax attributable to it. The foreign tax paid is not automatically both an expense deduction and a tax credit.

4. One transaction, several laws

Consider a fictional company, Tamarind Studio Ltd. It imports equipment, employs two people, and sells design services.

Importing the equipment: investigate tariff classification, customs value, origin and any customs or excise liability. Import VAT is a separate question. The fact that a supplier is overseas does not answer those questions.

Using the equipment: the accounting cost and depreciation need to be connected to the income-tax rules for allowable expenditure and capital allowances. Paying import charges does not settle the income-tax treatment.

Paying the team: the company must consider its employer obligations. PAYE, social contributions, employment entitlements and reporting should not be combined into a single undefined “salary tax”.

Billing the customer: decide whether the supply is within VAT, exempt or zero-rated under the applicable rules. An overseas customer does not automatically establish zero-rating. Any withholding requirement is also analysed under its own provision.

Buying an office: property-transfer duties and registration issues may arise even if the company has made no taxable profit.

The lesson is to connect obligations without merging them. A reliable analysis records each tax base, liable person, collector, period, exemption and source separately.

5. Use the right date—and keep the evidence

This edition freezes its research at 19 September 2026. That does not mean every rule applies from that date.

The Finance Act 2026 changes the individual income-tax bands for the income year beginning 1 July 2026: the first Rs 500,000 of chargeable income is at 0%, the next Rs 500,000 at 10%, the next Rs 11 million at 20%, and the remainder at 35%. These are bands applied to chargeable income, not a flat rate applied to the whole salary.

The same Act creates an insurance premium tax for specified general insurance business that starts on 1 January 2027. At this course’s cut-off, that is an enacted future measure. It must not be added to a September 2026 premium as though already operative.

A practical evidence pack

For a business transaction, retain the contract, invoices, accounts and tax adjustments, the source and residence analysis, supporting exemption documents, and proof of any foreign tax. Identify the return and period to which the result belongs.

If an assessment is disputed, locate the current objection and appeal provisions immediately. Do not use a generic remembered deadline: the tax, decision, procedural stage and effective version of the law matter. The 2025 Revenue Tribunal legislation and 2026 Rules belong in a current research file.

Before writing “tax payable”, be able to finish this sentence: “For this taxpayer, on these facts, in this period, this provision produces this result.”

Next: take that method across borders, where domestic rules and treaty limits have to be read together.
