Economic substance refers to a transaction that has a purpose besides the reduction of tax liability. The concept is used in the examination of tax shelters to see if they are abusing the tax laws.

Economic Substance Requirements In Mauritius
BELOW ARE THE ECONOMIC SUBSTANCES REQUIREMENTS IN MAURITIUS:
Stage 1 – Tax Residency Criteria in Mauritius
It is important to note that the definition of “tax residency” of companies has been amended in both 2018 and 2019.
Prior to 2018, a company incorporated in Mauritius or which has its Central Management and Control (CMC) in Mauritius would be considered a tax resident in Mauritius. Effective 01 July 2019, when a company’s CMC is outside Mauritius, the company will not be considered a tax resident of Mauritius, regardless of being incorporated in Mauritius.
This could subsequently jeopardise companies obtaining Tax Residency Certificates which would in turn prevent these companies from availing of treaty benefits.
Stage 2 – Imposition of substance requirements on Mauritius resident entities
Effective 01 January 2019, Mauritius replaced the deemed tax credit with the partial tax exemption, subject to grandfathering provisions.
To avail of the newly introduced partial exemption which is available on certain income streams such as dividend and interest income, companies are required to satisfy the substance requirements in Mauritius.
The substance requirement test can be split into two parts for better comprehension.

Test 1: Substance requirements

— Incur a minimum level of expenditure and employ directly or indirectly an adequate number of qualified persons.
Test 2: Core Income-Generating Activities
