As per Income Tax Act 1995

As per Income Tax Act 1995, income tax shall be paid by every person on all income, other than exempt income, derived by him in the preceding year and shall be calculated on the chargeable income of the person at a specified rate. Preceding year means the financial year before the assessment year. For instance, in Mauritius, the fiscal year runs from 1 July to 30 June.
Every person is denoted as any individual or company, who generated incomes within Mauritius or by Mauritians overseas. A person who is resident will be taxed on the worldwide income derived by him, in other words, on his Mauritius and foreign source of income remitted to Mauritius.
Provided that, in the case of a non-resident person, he will be taxed only on his Mauritius-source income.
The computation of income tax can be laid by the following steps:
• Calculate the Gross income deriving from all resources, excluding exempt income.
• Subtract all allowable deductions and exemptions.
• Apply the tax rates on the chargeable income.

In the new budget 2018/19, a retired person whose annual emoluments does not exceed Mur 50,000 will also be eligible to enhanced IET.

The IET is available for residents only.
