GS3 – Indian Economy –

This topic is relevant for both Prelims and Mains as the article discusses the amendment to the Double Taxation Avoidance Agreement (DTAA) with Mauritius, which has significant implications for India’s economy, particularly in terms of foreign investments and tax policies.


  • India has recently signed a protocol amending the Double Taxation Avoidance Agreement (DTAA) with Mauritius, aiming to address treaty abuse for tax evasion or avoidance.
  • The amendment introduces the Principal Purpose Test (PPT) to ensure that tax benefits under the treaty are not exploited for ulterior motives.
More about the news:

Inclusion of Principal Purpose Test (PPT):

  • The amended protocol incorporates Article 27B, defining the ‘entitlement to benefits’ and outlining the conditions under which treaty benefits, such as reduced withholding tax on interest, royalties, and dividends, will be denied if obtaining those benefits was a principal purpose of the transaction.

Historical Context and Impact:

  • Mauritius has been a preferred jurisdiction for investments in India, particularly due to the non-taxability of capital gains until 2016.
  • However, the amendment in 2016 allowed India to tax capital gains from the sale of shares acquired by Mauritian tax residents.
  • The recent amendment aims to address ambiguities and prevent tax treaty abuse but lacks clarity on the treatment of past investments.

Potential Rise in Litigation:

  • While the amendment aims to curb tax treaty abuse, experts anticipate a surge in litigation as investors from Mauritius will now need to substantiate the commercial rationale behind their transactions.
  • Ambiguities remain regarding the application of the PPT to grandfathered investments, necessitating guidance from the Indian government.

Alignment with Global Efforts and BEPS Framework:

  • The amendment reflects India’s commitment to align with global efforts against treaty abuse, particularly under the Base Erosion and Profit Shifting (BEPS) framework.
  • However, India is yet to announce Pillar Two amendments in its domestic tax laws, which are expected to be addressed post-elections, possibly in the budget in July 2024.


  • Over 135 jurisdictions have agreed to implement a minimum tax regime for multinationals under Pillar Two, with the OECD releasing the Global Anti-Base Erosion (GloBE) rules.
  • These rules propose a global minimum corporate tax rate set at 15%, aiming to generate additional global tax revenues annually.
  • The Pillar Two framework emphasizes coordinated taxation to prevent profit shifting and ensure a level playing field in the global tax landscape.
About DTAA
  • A Double Taxation Avoidance Agreement (DTAA) is a bilateral agreement between two countries aimed at eliminating the possibility of double taxation on the same income or financial transaction.
  • Such agreements are crucial for promoting international trade and investment by ensuring that individuals and businesses do not face excessive tax burdens when conducting cross-border activities.
  • DTAA typically outlines the rules for allocating taxing rights between the two countries involved, along with mechanisms for resolving disputes and exchanging information to prevent tax evasion. These agreements provide clarity and certainty for taxpayers, encouraging economic cooperation and facilitating the flow of capital across borders.
  • The objective of DTAA:
  • In the era of globalization, where investors operate across borders, the objective of Double Taxation Avoidance Agreements (DTAAs) is to prevent the occurrence of double taxation.
  • Double taxation arises when the same income or profit is taxed by two or more countries, leading to financial disincentives and unfairness.
  • International Taxation and DTAAs:
  • DTAAs are bilateral agreements signed between countries to address the issue of double taxation. These agreements ensure that income or profits earned by an investor in one country are not subject to taxation in both the home country and the host country.
  • Benefits of DTAAs:
  • Fairness and Boost to Investment:
  • DTAAs contribute to fairness in international taxation, fostering a conducive environment for investment and economic growth.
  • They eliminate the deterrent effect of double taxation, encouraging financial integration and cross-border investments.
  • Tax Treatment for Specific Incomes:
  • DTAAs often define specific tax treatment for various types of income, such as capital gains or royalties, providing clarity and predictability for taxpayers.


Practice Question:  Discuss the implications of the recent amendment to the Double Taxation Avoidance Agreement (DTAA) between India and Mauritius. Evaluate the potential impact of these amendments on foreign investments, bilateral relations, and India’s efforts to align with global tax governance frameworks. (250 words/15 m)


8. Chital Overpopulation in Andaman and Nicobar Islands Sparks Concern Over Invasive Species Management

Topic: GS3 – Environment – Environmental Pollution and Degradation

This topic is relevant for both Prelims and Mains in the context of Understanding the concept of invasive alien species, their definition, examples, and impact on native ecosystems.


  • The teeming population of chital (spotted deer) in Ross Island has prompted the Andaman and Nicobar Islands administration to seek assistance from the Wildlife Institute of India.
  • Originating from mainland India, chital were introduced to the Andamans by British game hunters in the early 20th century.
  • Lacking natural predators or competitors, these deer have proliferated across the islands.
More about the news:

Invasive Alien Species (IAS):

  • The Convention on Biological Diversity (CBD) defines invasive alien species (IAS) as those whose introduction and spread outside their natural distribution threaten biological diversity.
  • In India, the legal definition of IAS, under the Wildlife Protection Act, 1972 (amended in 2022), is narrower, excluding species within India that may be invasive to a specific region, such as chital in the Andamans.

Examples of IAS in India:

  • India’s list of invasive wildlife is dominated by certain fish species like the African catfish, Nile tilapia, red-bellied piranha, and turtle species such as the red-eared slider.
  • These species, often introduced by human intervention, outcompete native species for resources and disrupt local ecosystems.

Impact of IAS on Native Species:

  • IAS disrupt food chains and ecosystem balance, often dominating habitats where there is no competition.
  • For example, chital in the Andamans have impacted the regeneration of native vegetation by consuming seeds and seedlings.
  • In places like Keoladeo National Park in Rajasthan, invasive species like the African catfish have been known to prey on water fowl and migratory birds, affecting biodiversity.

Economic Impact of IAS:

  • According to a report by the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES), the global economic cost of IAS was over $423 billion annually in 2019.
  • These costs arise from the damage inflicted by IAS on natural ecosystems, leading to yield losses in crops like cotton due to invasive pests like the cotton mealy bug.


  • The management of invasive alien species like chital in the Andaman and Nicobar Islands is crucial for preserving native biodiversity and mitigating economic losses caused by their proliferation.
  • Collaborative efforts between wildlife authorities, research institutions, and local communities are essential to address this challenge effectively.
               Factors Responsible for Rising Invasive Species:


Globalization of Trade and Travel:

  • Increased international trade and travel have facilitated the unintentional movement of species across borders.
  • Cargo ships, airplanes, and vehicles can inadvertently carry invasive species within cargo, through ballast water, or attached to their surfaces, facilitating their unintentional spread.
  • Introduced to Australia in the late 1800s via shipwrecks and the pearling industry, the Black Rat is regarded as one of the “World’s Worst” invasive species by the IUCN.
  • Climate Change:
  • Elevated temperatures and shifts in precipitation patterns promote environments conducive to the colonization and proliferation of invasive species.
  • Shifts in the timing of seasons can disrupt the life cycles of native species, making them more susceptible to invasive competitors and predators.
  • Human Introduction of Exotic Species:
  • Deliberate introduction of non-native species for purposes like gardening, landscaping, and pest control can lead to invasions when these species escape cultivation.
  • International Instruments and Programmes on Invasive Species:
  • Kunming-Montreal Global Biodiversity Framework (2022): Governments have committed to reducing the rate of introduction and establishment of invasive alien species by at least 50% by 2030.
  • Convention on Biological Diversity (CBD – 1992): Adopted at the 1992 Earth Summit in Rio de Janeiro, it recognizes invasive alien species as a major threat to the environment, second only to habitat destruction.
  • Convention on the Conservation of Migratory Species (CMS – 1979): This intergovernmental treaty aims to conserve migratory species and includes measures to control or eliminate invasive alien species already present.
  • Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES – 1975): Focuses on ensuring international trade does not threaten the survival of wild animals and plants; it also considers the impact of invasive species involved in trade


PYQ: With reference to the International Union for Conservation of Nature and Natural Resources (IUCN) and the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which of the following statements is/are correct? (2015)

1) IUCN is an organ of the United Nations and CITES is an international agreement between governments.

2) IUCN runs thousands of field projects around the world to better manage natural environments.

3) CITES is legally binding on the States that have joined it, but this Convention does not take the place of national laws.
