Key Takeaways
- Withholding tax in Mauritius applies to defined categories of payments, including interest, royalties, services and dividends, each treated according to its type.
- Payers making qualifying payments are responsible for deducting, remitting and filing the tax, with penalties applying where these obligations are not met.
- Domestic exemptions and reliefs may reduce or remove the withholding obligation for certain payments, so non-residents should confirm how their case is treated.
- Foreign-owned businesses should review their payment flows against the scope and compliance rules to manage their withholding tax position correctly.
Understanding Withholding Tax in Mauritius
Withholding tax in Mauritius applies to certain payments crossing from a paying business to a recipient, and the rate runs from 0% to 15% depending on the nature of the payment and the residence of the person receiving it. The framework sits within the Income Tax Act 1995, administered through a self-assessment system overseen by the Mauritius Revenue Authority.
This is not a blanket levy. Dividends paid by resident companies carry a domestic rate of 0%, while interest and royalties are the categories where withholding genuinely bites.
The article explains which payments trigger a deduction, the applicable rates, the exemptions a foreign-owned entity can rely on, and the filing and remittance duties that follow. It will be most useful to non-resident owners and their advisers weighing an investment structure or holding company routed through the island.
Legal Basis and Scope of Withholding Tax
The governing texts are the Income Tax Act 1995 and the Income Tax Regulations 1996. Together they set out who must withhold, on what payments, and at what rate.
Central to the regime is the concept of a "payer." Under Section 111A of the Act, that term deliberately excludes individuals and any company whose annual turnover does not exceed MUR 6 million, so smaller entities and private persons carry no withholding duty at all.
The reach of tax depends on residence. A company resident on the island is taxed on worldwide income, whereas a non-resident corporation answers only for income sourced locally, subject to any treaty that applies.
That treaty layer matters for foreign owners. The jurisdiction has 46 double tax treaties in force, and these can lower the domestic rate that would otherwise apply to a non-resident recipient.

Payments Subject to Withholding Tax
Three categories sit at the centre of the regime: dividends, interest, and royalties. A business making any of these payments to another entity or to an individual must consider whether deduction at source is required.
The treatment differs sharply by category. Dividends from resident companies are exempt; interest payable to non-residents is caught; royalties to both residents and non-residents attract a deduction.
Several payments fall outside the net entirely. Interest, rents, royalties, compensations, and similar amounts paid by a special purpose fund established under the Financial Services Act 2007 to a non-resident are exempt, as are gains from the sale of units, securities, or debt obligations.
A turnover floor also removes many firms from the obligation. Companies with annual turnover below MUR 6 million are not treated as payers and therefore do not withhold.
Withholding Tax Rates by Payment Type
The table below sets the headline domestic rates before any treaty relief is considered.
| Payment Type | Resident Rate | Non-Resident Rate |
|---|---|---|
| Dividends | 0% | 0% |
| Interest | 15% | 15% |
| Royalties | 10% | 15% |
Royalties are the one category where resident and non-resident outcomes part ways. For a resident payee, the 10% deducted counts as an advance payment and is credited against that person's eventual income tax bill.
For a non-resident, the position is final. The 15% withheld on royalties discharges the liability in full, with no further return required from the recipient.
Interest sits at 15% for both residents and non-residents, with an important exclusion for banks and non-bank deposit-taking institutions licensed under the Banking Act.

Withholding Tax on Interest Payments
Interest flowing to a non-resident attracts 15% at source, unless a double tax treaty sets a lower figure. The deduction applies to interest paid by any person other than the licensed banks and deposit-takers noted above, and where the recipient is not a Mauritius-resident company.
A foreign owner using a Global Business Licence vehicle should note two carve-outs. Interest paid by a GBL company to a non-resident out of foreign-source income is exempt, and interest paid by a licensed bank to a non-resident not trading locally, out of income from its banking dealings with non-residents and GBL corporations, is likewise free of withholding.
Treaty relief can move the rate meaningfully. Under the India treaty, for example, interest is taxed at 10% where the beneficial owner is a financial institution, insurance company, or investment company drawing income from financial investments, and at 15% otherwise.
On the receiving side, the treatment of interest earned by a resident entity is worth understanding. Such income is taxable at 15%, but interest other than bank interest may qualify for an 80% partial exemption on the gross amount, provided the prescribed substance conditions are met.
A wider concession applies to certain funds. Interest derived by a Collective Investment Scheme or Closed-End Fund licensed or approved by the FSC qualifies for a 95% exemption.
Withholding Tax on Royalties
Royalties paid to a resident face a 10% deduction. Because this is treated as an advance payment, the resident payee recovers it against income tax due, so the economic burden falls only on the final assessment.
Where the recipient is a non-resident, the rate is 15% and the character changes. That deduction is the final tax on the royalty, closing the matter for the foreign recipient.
One exemption is significant for cross-border structures. Where a company pays a royalty out of foreign-source income to a non-resident, no withholding is required.
Treaties can compress the rate further. Some agreements set 5% on royalties paid for the use of a copyright in literary, artistic, or scientific work, excluding cinematograph films and tapes or discs used for radio or television broadcasting.
For a non-resident, withholding on interest and royalties is generally the final tax; for a resident, royalty withholding is creditable against the year's liability.

Withholding Tax on Services and Specified Payments
There is no standalone withholding category for general service fees comparable to regimes found elsewhere. Payments for services to a non-resident are not, of themselves, subject to a separate domestic deduction, though they may still attract income tax if the activity produces locally sourced income.
The Section 111A definition again limits who must act. Individuals and companies with turnover at or below MUR 6 million are outside the withholding obligation altogether.
Employment income follows a different track. Every employer must register with the revenue authority and deduct tax from emoluments at the point they are made available, through the Pay As You Earn (PAYE) system, which is the route by which most employees settle their tax.
Withholding Mechanism for Dividend Payments
No withholding tax arises on dividends distributed by a resident company, including distributions to foreign shareholders. This is the principal area where the regime imposes nothing.
The exemption is broad and applies regardless of the recipient's residence. Companies, whether resident or not, are exempt from tax on dividends received from a Mauritian resident company, and individuals enjoy the same treatment on cash or share dividends from such companies.
The relief is anchored in Part II of the Second Schedule to the Income Tax Act, which lists exempt income. Treaty rates for dividends are recorded in agreements only for completeness, since they would bite only if the domestic rate were higher than zero.
Inbound dividends are a separate matter. A resident company receiving dividends from abroad is taxed at 15%, but may claim either the 80% partial exemption on the gross amount or a credit for foreign tax already withheld.
Domestic Exemptions and Reliefs from Withholding Tax
A foreign-owned structure has several routes to reduce or remove withholding. The most useful for holding and financing vehicles is the foreign-source income carve-out, which applies across more than one payment type.
- Payments by a GBL company to a non-resident not trading locally, made out of foreign-source income, carry no withholding.
- Interest paid by a GBL corporation to such a non-resident, out of foreign-source income, is exempt.
- Royalties paid by a company to a non-resident out of foreign-source income fall outside the deduction.
- Interest, rents, royalties, and similar sums paid by a special purpose fund under the Financial Services Act 2007 to a non-resident are exempt.
- Payments by a company with annual turnover below MUR 6 million are not subject to withholding.
Two structural features support cross-border planning. There is no capital gains tax on the island, and an income tax exemption is available for companies set up on or after 1 July 2017 engaged in innovation-driven activity for intellectual property developed locally.
Treaty access carries a procedural step. A GBL company seeking treaty benefits must obtain a Tax Residence Certificate from the revenue authority, typically issued within seven days of application where the required return under the Act has been filed.
If your structure relies on a treaty rate, secure the Tax Residence Certificate before distributions begin; certify-then-pay avoids contested deductions.
Compliance, Remittance, and Filing Obligations
Tax administration runs on self-assessment. Persons liable must file declarations for the relevant periods and pay according to those declarations, with the consolidated Income Tax Act setting out the detail.
The key dates for a withholding agent and the entity behind it are set out below.
| Obligation | Deadline |
|---|---|
| Withheld tax (PAYE/WHT) remittance | Within 20 days from the end of the month of deduction |
| Annual corporate return | Within six months from the end of the accounting-year month |
| Individual return and payment | 30 September (15 October if filed and paid electronically) |
| Employer reconciliation and return of employees | 15 February |
Companies with larger turnover also face quarterly obligations. The Advance Payment System requires quarterly statements and payments, each due within three months after the end of the quarter, but it does not apply to a company with turnover below MUR 10 million.
Where an accounting year ends on 30 June or 31 December, the annual return falls due two working days before the end of June or December respectively. Filing and payment for companies deriving gross or exempt income must be done electronically.
Penalties for Non-Compliance with Withholding Tax
A payer who fails to deduct withholding tax becomes personally liable for it, keeping only the right to recover the amount from the payee. Late payment of the sum due adds a penalty of 5% of the tax.
Interest accrues on top. The charge is 0.25% per month, or part of a month, on the outstanding balance after the due date.
Late filing carries its own scale. A person required to submit a return who fails to do so pays MUR 2,000 for each month of delay, capped at MUR 20,000.
Adjustments under the quarterly system attract a late payment penalty of 5%, reduced to 2% for companies with turnover at or below MUR 10 million. The Director-General may waive penalty or interest, in whole or part, where the failure had a just or reasonable cause.
Conclusion
Withholding tax in Mauritius places the compliance burden squarely on the payer, which means a foreign owner's real exposure depends less on the headline rates and more on whether the entity making the payment has correctly identified its obligation and remitted on time. For a non-resident deciding how to structure outbound payments of interest, royalties, or service fees, the exemptions and reliefs are where the material difference lies, and confirming whether a specific payment qualifies for relief is the one step that cannot be deferred.
Penalties for missed remittances accrue regardless of intent, so the immediate practical priority is mapping existing payment flows against the categories the rules cover before the next payment cycle runs.
