The Fair Share Contribution Charged to Large Companies

The fair share contribution in Mauritius is an additional charge on larger, more profitable companies. It sits outside the ordinary corporate income tax computation and is found in a different statute, which is why many owners meet it only when a tax adviser mentions it. This page sets out which companies are within scope, the special treatment of banks, how the charge differs from other levies, and what a board should check each year.

It is general information, not advice. Whether a particular company is caught depends on its figures for the year, so the final analysis belongs with a qualified adviser.

What the fair share contribution is

The company version of the fair share contribution is governed by Part XC of the VAT Act, even though it has nothing to do with value added tax as such. It is a contribution assessed on income, and the legislation places it in that Act.

Two points are worth keeping apart from the start:

• It is a company charge and an individual charge with the same name. The individual version is a separate provision of the Income Tax Act and has its own conditions (see below).
• It is not the CSR contribution. The CSR regime is covered on its own page: CSR contribution for Mauritian companies.

Who is concerned: the income test

Under Part XC of the VAT Act, the contribution applies to companies whose taxable income exceeds MUR 24 M in the financial year.

Until recently a turnover criterion also played a part in deciding who was caught. Since the Finance Act 2026, with effect from 13 August 2026, the turnover criterion has been removed. The test now rests on the income threshold alone. A company that last year reasoned on the old two-part test should therefore re-run the analysis with the current wording.

A quick way to place your company

The tree is a screening aid only. The figure that matters is the income as finally computed for tax purposes, not the profit shown in management accounts. For how that figure is reached, see how a Mauritius company is taxed on its profits.

Special levy on banks

Banks are treated differently, which is why searches for a "special levy banks Mauritius" lead to the same provision. A bank pays the contribution at 5 % of its taxable income. It also pays an additional contribution at 2.5 % on income arising from transactions with residents, a category that excludes global business entities. The total of these charges is capped at 35 % of the taxable income concerned.

This bank regime applies for the period from 1 July 2025 to 30 June 2028. Because it is a time-limited measure, any planning that extends beyond that period should be reviewed against the law as it then stands.

The rate applying to non-bank companies is not reproduced here because it is not among the facts we have verified. Rather than quote a figure from memory, take it from the text of Part XC itself, listed under Sources.

The individual version, for comparison

Individuals also have a fair share contribution, set at 15 % on leviable income above MUR 12 M under section 16C of the Income Tax Act. It applies only to income of the year beginning 1 July 2025: the Finance Act 2026 deleted the reference to the two following years. A company owner who receives a large salary or dividend should not assume the company rules and the personal rules move together.

How it differs from other charges on profitable companies

Several charges can land on the same company in the same year, and they are easily confused.

The standard corporate income tax rate is 15 % of taxable income for years starting on or after 1 July 2010. The levies above are in addition to the tax computation, not a replacement for it, except that the Alternative Minimum Tax operates as a floor on the tax payable. Do not treat any one of them as a substitute for another.

The CCR Levy, briefly

The Corporate Climate Responsibility Levy is the one most often mistaken for the fair share contribution. It is 2 % of chargeable income, due for the year beginning 1 July 2024 and each later year, and no levy arises where turnover for the year does not exceed MUR 50 M. Since the Finance Act 2026, a company in the quarterly advance payment system pays it in three instalments of 25 % with the advance payment returns, then settles the balance with the annual return. Other companies pay it with the annual return. See the advance payment system for companies for how those instalments are filed.

When it is paid

The facts we have verified do not set out a separate due date for the company fair share contribution, and we prefer to say so rather than guess. In practice the payment and the return should be considered alongside the company's annual tax cycle. Check the following with your adviser or in the Part XC text:

• the exact due date and the form on which the contribution is declared;
• whether the contribution follows the advance payment instalments or is settled with the annual return;
• what interest or penalty follows a late payment.

Our compliance calendar lists the recurring filings that normally surround this payment, and filing with the MRA online shows how the submission itself is made.

A practical routine for the board

• Compute taxable income for the year early, not at the filing deadline
• Compare it with the MUR 24 M threshold after all adjustments
• Confirm whether the company is a bank or falls within any special regime
• Separate the CCR Levy, Alternative Minimum Tax and fair share analyses, so that none is skipped
• Record the computation and the date of payment in the board papers
• Keep the working with the tax return, since the corporate income tax return draws on the same figures

The figures that feed this test come from the year's accounts, so late or unreliable accounts delay the whole sequence. Preparing annual financial statements explains how to keep that step on schedule.

Where residence and structure can matter

A company incorporated in Mauritius is tax resident there if it is incorporated in Mauritius or if its central management and control are in Mauritius (section 73). Section 73A treats a Mauritius-incorporated company as non-resident when it is centrally managed and controlled outside Mauritius, but it must still file an income tax return under section 116. These residence rules shape which income is taxed at all, so they come before any levy analysis. Whether a given structure ends up inside or outside a particular charge turns on its facts, and that is an adviser's judgement.
