Key Takeaways
- Liability for personal income tax in Mauritius depends on residence status and on whether income is sourced locally or remitted to the country.
- Non-resident individuals and expatriates face specific rules, alongside distinctions between employment, self-employment, and business income.
- Filing involves submitting returns under the Current Payment System (CPS) and meeting set payment deadlines, with reliefs and allowances available to reduce taxable income.
- Ongoing reforms, including the Fair Share Contribution for high-income earners, shape the outlook that non-resident taxpayers should monitor.
Understanding Personal Income Tax in Mauritius
Personal income tax in Mauritius is a real, levied charge on individuals, not a token to be ignored by foreign owners and investors. The tax is governed by the Income Tax Act 1995 and administered by the Mauritius Revenue Authority on a self-assessment basis, with progressive rates rising to 20%. For residents, a remittance-based regime applies, which limits exposure on foreign-source income; a fuller explanation of that mechanism appears below and in the PwC tax summary.
This article sets out the rules a non-resident business owner or adviser needs to assess liability and stay compliant: who is taxed, on what income, at what rates, and by when. It is most useful to foreign individuals earning income from a Mauritian entity, expatriate employees, and the advisers structuring their affairs.
The income year runs from 1 July to 30 June of the following year. There is no capital gains tax, no net wealth tax, and no inheritance, estate, or gift tax.
Legal Basis: The Income Tax Act 1995 and Who Is Liable
The Income Tax Act 1995 is the primary statute, supplemented by the Income Tax Regulations 1996 and amended through successive Finance Acts. The most consequential of these for individuals is the Finance Act 2025 (Act No. 18 of 2025), published in the Government Gazette on 9 August 2025.
Liability turns on the source of income and residence status, not nationality. Any individual deriving income from Mauritian sources is taxed on that income, whether resident or not.
Residents are assessed on worldwide income, but foreign-source income is taxable only to the extent it is received in the country. Non-residents are taxed only on net income arising locally, and they cannot claim the reliefs, deductions, and allowances available to residents.
The arm's-length principle for related-party dealings is embedded in the legislation and applies where individuals transact with connected entities. For most foreign-owned arrangements, the practical question is simpler: where does the income arise, and is the recipient resident?

Residence-Based Liability and the Source vs. Remittance Rule for Individuals
Residence is treated fully in a separate article, so this section addresses only what bears directly on income tax. An individual is generally resident where they are present for 183 days or more in an income year, or for an aggregate of 270 days across the year and the two preceding ones, or where their domicile is in the country and their permanent home is not elsewhere.
The remittance rule is the feature foreign owners most need to understand. A resident is taxed on income generated in or from Mauritius and on foreign income only when that money is brought into the country.
Foreign investment income is taxable in a resident's hands when received or dealt with locally. A foreign tax credit for tax already paid abroad is allowable against the local charge, which in practice usually eliminates any further tax on such income.
Employment is treated differently. Income from employment duties performed in Mauritius is deemed to arise there, even where the salary is paid into a foreign account.
Budget 2026-2027 proposals would tax foreign employees on foreign employment income only where remitted, and would treat local spending via a foreign card as not constituting remittance. These remain proposals until enacted.
The Supreme Court has interpreted the interaction of the remittance and residency rules in the "Dilloo Case," underlining that the application of these tests is fact-specific.
Current Tax Rates and Income Bands
Effective 1 July 2025, the structure was simplified from eleven bands to three: a nil rate, a standard middle-band rate, and a top rate of 20%. This replaced the progressive system introduced on 1 July 2023, which had itself ended more than a decade of a flat 15% charge.
The first MUR 500,000 of chargeable income is taxed at 0%. An employee or self-employed individual earning up to MUR 1 million annually pays no income tax. At the upper end, individuals with annual net income above MUR 24 million are taxed at 20%.
The three-band structure includes a standard middle-band rate between 0% and 20%. Confirm the exact middle-band rate and its threshold on the MRA personal income reference before relying on it.
The monthly threshold for an employee to qualify as an "exempt person" rose from MUR 30,000 to MUR 38,462, effective 1 July 2025. Income from dealings in units and securities is exempt from tax.

The Fair Share Contribution for High-Income Earners
A Fair Share Contribution applies to individuals with substantial income, introduced by the Finance Act 2025. It runs as a temporary measure from 1 July 2025 to 30 June 2028.
Where net income exceeds MUR 12 million (roughly USD 265,000), a 15% charge applies to the excess above that threshold. The contribution sits on top of ordinary income tax rather than replacing it.
The base differs from ordinary income tax in one important respect. Dividends from companies based in Mauritius are included in the contribution calculation, even though such dividends are excluded for income tax purposes; dividends from trusts and foundations are left out.
| Feature | Detail |
|---|---|
| Threshold | Net income above MUR 12 million |
| Rate | 15% on the excess |
| Period | 1 July 2025 to 30 June 2028 |
| Dividends from local companies | Included in the base |
| Foreign tax credits | Cannot offset the liability |
For payroll, employers apply 15% under PAYE on the portion of cumulative chargeable income that exceeds the cumulative contribution threshold. Foreign tax credits cannot reduce this liability, a point that matters for high earners structuring cross-border affairs.
The measure drew criticism over its effect on foreign direct investment and the country's standing as a financial centre, with FDI flows declining from MUR 37.01 billion in 2023 to an estimated MUR 32.99 billion in 2024. Budget 2026-2027 proposes replacing the contribution with a permanent 35% high-income band.
Employment Income vs. Self-Employment and Business Income
Employment income exercised in Mauritius is taxable regardless of where payment is made or who the employer is. The definition is broad, covering salary, wages, fees, overtime, bonuses, commissions, gratuities, pensions, compensation for loss of office, and benefits in kind.
Benefits in kind include the annual value of residential accommodation, company cars, free meals, and full board. Most are valued at standard scale rates that fall below the actual cost to the employer, which softens their tax effect.
Tax on employment income is collected through the Pay As You Earn system, withheld monthly by the employer and remitted to the revenue authority. Passages by sea, air, or land between the country and abroad provided under a contract of employment are exempt up to 6% of basic salary.
Self-employed individuals are taxed on net profits under the Current Payment System. Deductions are allowed for outgoings incurred wholly and exclusively in producing assessable income, together with capital allowances on qualifying assets.
A small enterprise may elect a presumptive tax of 1% of gross income, but it then forgoes all reliefs, deductions, and allowances. Eligibility requires gross income not exceeding MUR 10 million in the income year, with income from other sources capped at MUR 400,000.
Limited partnerships are tax-transparent, so partners are taxed on their respective income shares rather than the partnership being charged directly.

Personal Reliefs, Allowances and Deductions
Reliefs and deductions reduce total net income to arrive at chargeable income, and they are available to residents only. Non-residents cannot claim them, which is a material difference when comparing after-tax outcomes.
A dependent means a spouse, a bedridden next of kin under your care, a child under 18, or an older child in full-time education or unable to earn a living through disability. Deductions may be claimed for up to four dependents, by either spouse, and a married woman is assessed separately with full access to reliefs in her own right.
Several reliefs reward specific outlays:
- An additional MUR 500,000 claim where a dependent child pursues a non-sponsored, full-time undergraduate or postgraduate course at a recognised tertiary institution.
- No exemption for an undergraduate course where annual tuition (excluding administration and union fees) is below MUR 34,800 for a course in Mauritius, or where the same dependant has been claimed for more than six years.
- Relief on interest paid on a housing loan secured by mortgage on a home, withdrawn where the income of the person or spouse exceeds MUR 4 million in the income year.
Exempt income includes dividends, interest, capital gains, qualifying lump sums, medical expense refunds, and certain travelling expenses. Deductions and reliefs are applied through the Employee Declaration Form process. The full set of conditions appears on the MRA reliefs page.
Special Rules for Expatriates and Non-Resident Individuals
Expatriates working locally are taxed on employment income exercised in the country, on the same footing as resident employees for that income. Non-residents, by contrast, are taxed only on net income arising locally and receive no reliefs or allowances.
There is no withholding tax on dividends paid to individuals, which simplifies repatriation for foreign shareholders. An extensive double tax agreement network allows treaty relief on a country-by-country basis; confirm the position for your home jurisdiction directly with the revenue authority.
Where you wish to be certified resident for an income year, an application for a Tax Residence Certificate is made to the Director-General. Two proposals in Budget 2026-2027 are relevant to expatriates: a four-year income tax exemption for qualifying employees of solar photovoltaic manufacturers, and relief from tax on funds deposited locally where a declaration confirms taxes were already paid abroad. Both remain proposals.
Filing Returns, the Current Payment System (CPS) and Payment Deadlines
An individual return covers the income year ending 30 June and must reach the revenue authority by 30 September. Filing electronically with payment by ATM, mobile payment, or direct debit extends the deadline to 15 October.
For employees, PAYE withholds tax cumulatively through the year, with any final adjustment made on the annual return. Employers must remit withheld tax electronically by the end of the month following the month of withholding.
If PAYE leaves tax underpaid, the balance falls due by 30 September after the income year ends; overpayments are normally refunded within three months of filing. Employees lodge their Employee Declaration Form electronically at the start of the year through the MRA e-filing portal to secure correct deductions.
Self-employed taxpayers report under the Current Payment System on a quarterly basis:
- Q1 (July to September): by end of December.
- Q2 (October to December): by 31 March.
- Q3 (January to March): by end of June.
- Q4: no statement; the annual return by 30 September covers it.
A CPS statement is required where gross income under CPS in the preceding year exceeded MUR 4 million and tax payable on chargeable income exceeds MUR 500. Credit card payment is available where the amount does not exceed MUR 25,000.
| Default | Penalty | Interest |
|---|---|---|
| Late PAYE remittance | 5% of unpaid tax | 1% per month or part month |
| Late CPS statement | MUR 2,000 per month, capped at MUR 6,000, plus 5% of tax | 0.5% per month until paid |
Recent Reforms and the Outlook for Personal Income Tax
The direction of travel has been steady. A flat 15% rate gave way to a progressive system on 1 July 2023, after which the Finance Act 2025 compressed eleven bands into three from 1 July 2025.
That same Act raised the monthly exempt-person threshold to MUR 38,462, lifted the exemption on retirement lump sums from MUR 3 million to MUR 3.5 million, and introduced the Fair Share Contribution. It also excluded certain disability-related social benefits received by a dependent child from the income calculation where a disability deduction is claimed.
Budget 2026-2027 sets out further change, though it is not yet enacted as a Finance Act. The proposals would replace the temporary contribution with a permanent 35% high-income band, limit the audit period to two years, and introduce voluntary compliance schemes allowing taxpayers to settle dues without penalty or interest.
For more than two decades the country operated as a low-tax base for businesses and high earners. The current trajectory moves toward greater progressivity while keeping investment structures such as Global Business Companies attractive.
Conclusion
For a foreign business owner, the residency question is not administrative detail but the variable that determines whether worldwide income, local income only, or a remittance-based slice of either falls within scope. Getting that classification right, before incorporating or relocating personnel, is where the real tax exposure is decided. The Fair Share Contribution signals that the rate structure is still moving, so any compliance model built today should be tested against the reforms already in motion rather than treated as settled.

Frequently Asked Questions
Residents are assessed on worldwide income, but foreign-source income is taxed only to the extent it is received in the country under the remittance rule. A foreign tax credit for tax paid abroad is allowable, which usually removes any further charge on foreign income.
The structure has three bands: 0% on the first MUR 500,000 of chargeable income, a standard middle-band rate, and 20% on annual net income above MUR 24 million. Individuals earning up to MUR 1 million annually pay no income tax.
Individuals with net income above MUR 12 million pay 15% on the excess, including dividends from local companies in the base. It runs from 1 July 2025 to 30 June 2028 and cannot be offset by foreign tax credits.
No. Non-residents are taxed only on net income arising locally and cannot claim the reliefs, deductions, and allowances available to residents. This is a key reason after-tax outcomes differ between resident and non-resident individuals.
The return for the income year ending 30 June is due by 30 September, extended to 15 October where you file electronically and pay by ATM, mobile payment, or direct debit. For the income year 2025, the deadline fell on 15 October 2025.
No withholding tax applies to dividends paid to individuals. Dividends are also exempt from ordinary income tax, though dividends from local companies are included in the Fair Share Contribution base.
