The historical root of the India-Mauritius tax dispute lies in the Double Taxation Avoidance Agreement (DTAA) signed on August 24, 1982, which entered into force on April 1, 1983. Originally intended to encourage bilateral trade and investment, the treaty allocated the right to tax capital gains on the sale of Indian shares solely to Mauritius. Because Mauritius does not levy capital gains tax, this created a 'double non-taxation' loophole, turning the island nation into a dominant conduit for routing foreign investments into India through shell companies, a practice known as treaty shopping.

Following India's economic liberalization in 1991, the Central Board of Direct Taxes (CBDT) issued Circular No. 789 in 2000, declaring a Tax Residency Certificate (TRC) as conclusive proof of residence to claim treaty benefits. This position was upheld by the Supreme Court in the landmark Union of India v. Azadi Bachao Andolan (2003) case. However, to curb tax avoidance, India and Mauritius signed an Amending Protocol on May 10, 2016, transitioning to source-based taxation for capital gains on shares acquired on or after April 1, 2017, while grandfathering older investments. Additionally, the General Anti-Avoidance Rule (GAAR) was operationalized on April 1, 2017, under Chapter X-A of the Income-tax Act, 1961, to target transactions lacking commercial substance.

The current conflict over indirect transfers and treaty benefits closely mirrors the landmark Vodafone International Holdings BV v. Union of India (2012) case, where the Supreme Court ruled that offshore share transfers between non-residents were not taxable in India, prompting retrospective legislative amendments. It also parallels the McDowell & Co. Ltd. v. Commercial Tax Officer (1985) case, which established early judicial limits on colorable tax avoidance devices in India.

The debate over fiscal sovereignty and the state's power to tax foreign wealth reflects the early nationalist critiques of colonial economic drain, such as Dadabhai Naoroji's 'Drain Theory' in the late 19th century, which emphasized the need for India to retain and tax its domestic wealth for national development.

When large-scale tax avoidance reduces the national exchequer's resources, the government may rely more on regressive indirect taxes, which disproportionately burden the daily purchasing power of common citizens. Furthermore, underfunded public services in health, education, and sanitation directly compromise the dignity and quality of life of impoverished populations.

This issue directly invokes Article 39(b) and Article 39(c) of the Directive Principles of State Policy (DPSP) under the Constitution of India, which mandate that the state prevent the concentration of wealth and distribute material resources for the common good. Additionally, it relates to the Right to Life under Article 21, as the state's ability to provide basic social security, healthcare, and education—essential for a dignified life—is contingent upon robust public revenue generation.

The primary ethical conflict lies in balancing economic efficiency (attracting Foreign Direct Investment by ensuring tax certainty and ease of doing business) against distributive justice (ensuring tax equity and preventing tax avoidance). A policymaker faces the dilemma of whether to prioritize short-term investor confidence or long-term sovereign tax rights to fund public welfare.

Tax avoidance through treaty shopping deprives the state of vital public revenue, directly limiting the fiscal space needed to fund targeted welfare programs for Scheduled Castes (SCs), Scheduled Tribes (STs), and the Economically Weaker Sections (EWS). This revenue deficit hinders the state's capacity to address multi-dimensional poverty and structural inequalities among these marginalized groups.
