Corporate Tax and Business Costs in Mauritius

How corporate income tax works

Corporate income tax is charged on taxable or chargeable income, not simply on turnover or money received into a Mauritian bank account. The starting point is commercial profit, adjusted for tax rules governing deductible expenditure, capital allowances, losses, exempt income and other items.

The Mauritius Revenue Authority currently states a standard company rate of 15%. A 3% rate applies to companies engaged in qualifying exports of goods. A business should confirm that its actual activity meets the statutory definition before using the lower rate in forecasts.

Partial exemptions and effective taxation

Mauritius provides partial exemptions for specified categories of income and activities. Depending on the category, the exemption may be 80% or 95%, but it is not a blanket benefit for all foreign income or every internationally active company.

Eligibility can depend on the precise source and character of income, regulatory status, economic substance and compliance with prescribed conditions. The responsible approach is to test each income stream separately and retain evidence supporting the treatment claimed.

• Do not assume that invoicing a foreign client automatically creates exempt income.
• Separate trading income, interest, dividends, royalties and service income in the analysis.
• Check whether the activity is regulated and whether local substance is required.
• Model the standard position as well as the position after any available relief.

Tax residence, substance and management

Incorporation in Mauritius is only one part of the residence analysis. Central management and control, treaty provisions and the rules of another country may also matter. A company whose commercial decisions are consistently made abroad can face competing residence claims or a permanent establishment outside Mauritius.

Substance should reflect the company’s real activity. Depending on the structure, this can include suitably qualified directors, documented strategic decisions, local expenditure, staff, premises, records and operational capability. Board minutes alone cannot replace commercial reality.

VAT: registration, invoices and cash flow

Mauritius VAT is generally charged at 15% on taxable supplies, while some supplies are zero-rated or exempt. Registration can become compulsory when the statutory turnover threshold is exceeded or when the business carries on an activity for which registration applies irrespective of turnover. Voluntary registration may be possible in appropriate cases.

VAT affects much more than the sales price. A company must consider invoice requirements, input-tax recovery, import VAT, filing frequency, payment dates and the time gap between collecting VAT and paying it to the authority.

Payroll and the true cost of employees

The employee’s gross salary is not the employer’s total cost. A realistic budget includes statutory payroll reporting and deductions, employer contributions, leave, end-of-year obligations where applicable, recruitment, immigration formalities for foreign staff, insurance, equipment, workspace and training.

Employers also need dependable monthly processes for payroll, PAYE and the applicable social contribution returns. Employment contracts and workplace policies should match current Mauritian labour law rather than imported templates.

Formation and first-year costs

Start-up budgets should distinguish statutory formation costs from the professional and commercial work needed to make the company operational. The cheapest incorporation package rarely represents the full first-year requirement.

Recurring annual compliance costs

Every active company should budget for recurring statutory and professional work. The exact package depends on company type, turnover, regulated status, staffing and the volume of transactions.

• annual registration and licence renewals;
• bookkeeping, payroll and management accounts;
• corporate tax, VAT, PAYE and other required returns;
• financial statements and audit where applicable;
• company-secretarial records and beneficial-ownership updates;
• registered office, insurance and professional advice;
• management-company, regulatory and substance costs for international structures.

Low transaction volume does not eliminate fixed compliance obligations. Conversely, a high-volume trading company may need more sophisticated accounting and controls even when its legal structure is simple.

Banking, payments and foreign exchange

Account maintenance, international transfers, correspondent-bank charges, card acquiring, payment gateways, guarantees and foreign-exchange spreads can materially affect margins. These costs should be modelled by currency and transaction corridor rather than represented as one generic bank fee.

A business receiving euros or US dollars while paying salaries and local suppliers in Mauritian rupees also carries currency risk. The spread between quoted and executable exchange rates may matter more than the visible transfer fee. See the dedicated guide to Corporate Banking in Mauritius.

Premises, imports and operating expenditure

Rent, deposits, fit-out, electricity, internet, vehicles, security, professional software and insurance vary considerably by location and activity. Import-dependent businesses must additionally model freight, customs duties where applicable, import VAT, port charges, storage, inland transport and delivery delays.

A sound launch plan includes a pre-revenue period and a working-capital buffer. Even a profitable business model can fail if deposits, inventory and customer payment terms absorb cash faster than expected.

Cross-border tax and owner-level exposure

Mauritian company taxation does not settle the position in the shareholder’s, director’s or customer’s country. Controlled-foreign-company rules, place-of-management tests, permanent establishments, transfer pricing, withholding taxes, dividend taxation and exit-tax provisions can alter the result.

Related-party charges must reflect real services and arm’s-length commercial terms. Treaties can allocate taxing rights or reduce double taxation, but they do not turn artificial arrangements into acceptable business structures.

Build a three-year total-cost model

Before incorporation, prepare a monthly cash-flow forecast for the first year and annual projections for at least two further years. Separate one-off, fixed, variable and tax-related costs. Then test a downside case with slower sales, delayed banking, higher imports and adverse currency movements.
