Income Tax in Mauritius

General reference only. This skill is general tax/accounting reference material for AI-assisted workflows. It has not been reviewed for any specific person's facts, documents, elections, deadlines, residency, filing status, or local procedures. Do not rely on it to file, pay, amend, or take a tax position without review by a qualified professional in the relevant jurisdiction.

Tax year covered: Income year 1 July 2026 to 30 June 2027 (year of assessment 2027/28).

Who this applies to

Individuals with Mauritius-source income, and residents with foreign income. Resident means domiciled in Mauritius unless the permanent place of abode is abroad, or present 183 days or more in the income year, or 270 days or more in aggregate over the income year and the 2 preceding income years (Income Tax Act s.73(1)(a)). The income year runs 1 July to 30 June. Non-residents are taxed on Mauritius-source income and get no reliefs, deductions or allowances (MRA foreign income page). Payroll mechanics sit in Payroll social. Foreign income rules sit in Cross-border.

The base

Chargeable income is gross income less allowable deductions, exemptions and reliefs (MRA obligation page). Employment expenses must be wholly, exclusively and necessarily incurred in the duties (s.17). Business and rental expenses must be exclusively incurred in producing the income (s.18). Losses, bad debts and annual allowance replace depreciation. Dividends from a resident company are exempt (Second Schedule Part II Sub-part B item 1). Where a person claims dependents, the spouse cannot also claim. "Dependent" covers a spouse, a child under 18, an older child in full-time education or unable to earn because of disability, and a bedridden next of kin eligible for the carer's allowance.

From 1 July 2026 a new exemption covers qualifying non-citizen employees installing, commissioning or operating a solar photovoltaic manufacturing plant, for 4 income years, and a disturbance allowance for public officers on tour in Rodrigues or the Outer Islands (Finance Act 2026 s.7(w)).

Deadlines and filing

1. Annual return: due 15 October after the income year, submitted electronically, tax paid at the same time (s.112(1)). The return for the year to 30 June 2027 is due 15 October 2027. Log in at MRA e-Services under File and Pay, Individual.
2. A person who has filed once keeps filing each year unless the Director-General agrees otherwise (s.112(1A)).
3. A self-employed person outside s.112 files a simplified return by the same date (s.112A).
4. CPS, by quarter (s.106): 1 July to 30 September is due 2 days before the end of December, excluding Saturdays and public holidays; 1 October to 31 December is due 31 March; 1 January to 31 March is due 2 days before the end of June, same exclusion. Quarter tax is computed on 25% of prior chargeable income scaled to CPS income (s.107), or on actual figures by option.
5. Statement of Assets and Liabilities: listed in the MRA calendar on the same 15 October date.
6. Presumptive tax: elect by irrevocable notice on or before the return due date, then pay with the return after offsetting tax withheld (s.111V).
7. A due date on a Saturday, Sunday or public holiday moves to the next working day (MRA calendar).

AUDIT FLASH POINT The MRA self-employed page still shows a 30 September return date, a 15% CPS rate and old penalties. The consolidated Act to Finance Act 2026 says 15 October and the penalties below. Follow the Act.

Cross-border points

Foreign income of a resident individual is derived when received in Mauritius or dealt with there for the person (s.5(3)). Premium visa and golden visa holders pay on remote-work income only when remitted (s.73B). Foreign tax credit and treaties are in Cross-border.

Two worked examples that recompute

Example 1. High earner. Resident, chargeable income Rs 15,000,000 in 2026/27. Tax is Rs 50,000 at 10%, Rs 2,200,000 at 20%, and Rs 1,050,000 at 35% on Rs 3,000,000: Rs 3,300,000.

name: Chargeable income Rs 15m, 2026/27 bands
inputs:
  income: 15000000
steps:
  - b10: (min(income, 1000000) - 500000) * 0.10
  - b20: (min(income, 12000000) - 1000000) * 0.20
  - b35: (income - 12000000) * 0.35
  - tax: b10 + b20 + b35
expected:
  tax: 3300000.00

Example 2. Decision: presumptive tax or normal tax. A qualifying small enterprise has gross income Rs 8,000,000, expenses Rs 7,000,000 and one dependent. Normal chargeable income is Rs 890,000, tax Rs 39,000. Presumptive tax is Rs 80,000. Normal tax wins here, by Rs 41,000. With expenses of Rs 5,000,000 the normal route costs more, so test both before electing, because the election is irrevocable.

name: Presumptive 1 percent against normal tax
inputs:
  gross: 8000000
  expenses: 7000000
  dependent: 110000
steps:
  - chargeable: gross - expenses - dependent
  - normal: (min(chargeable, 1000000) - 500000) * 0.10
  - presumptive: gross * 0.01
  - saving: presumptive - normal
expected:
  normal: 39000.00
  presumptive: 80000.00
  saving: 41000.00

Not yet confirmed: field-by-field steps of the individual e-return inside the login, which we could not open; the Thirteenth Schedule activity list was not copied here; the carer deduction amount; the MRA obligation page still shows the 2025/26 bands, and the Act governs 2026/27.
