  • States ask Centre to curb its ‘Cess’ habit

    cess

    Several States, including some governed by the Centre urged to rein in its reliance on raising revenues through cesses and surcharges which reduce their share in the divisible pool of taxes.

    What are Cesses and Surcharges?

    The Union government has the authority to collect money through a variety of levies referred to as a tax, fee, cess, and surcharge.

    (A) Cess

    • Cess is charged on the tax amount and is levied for a specific purpose.
    • In India, cess is applicable to all the taxpayers, and it is calculated over, and above the base tax liability of the taxpayer, cess taxes initially go to the consolidated fund of India (CFI) that has to be used for the purpose for which it was collected.
    • Education Cess, Swachh Bharat Cess

    (B) Surcharge

    • The surcharge is levied on the tax payable and not on the total income.
    • It directly goes to the CFI, and after that it can be used for any purpose, just like the normal tax.
    • Surcharge applies to the taxpayer whose income is more than Rs 50 lakh.
    • In simple terms, surcharge is a tax on tax that is not collected for any particular cause, and the union government may use the proceeds of surcharges for any purpose it sees as important.
    • The objective behind the surcharge is to put a high tax burden on people with high incomes.

    Difference between the two

    • The rate of cess under income tax is fixed at 4%, whereas the rate of surcharges varies from 10%, 15%, 25% & 37% based on the taxpayers’ total income.
    • Cess is calculated on total tax and surcharge amount; surcharge is calculated on total tax amount only.
    • In a nutshell, while both are taxes, cess is collected from every taxpayer to meet a certain purpose, and the surcharge is an additional tax collected from the taxpayers who have higher slab income.

    Key difference over which states dispute

    • Major difference is that each can be shared with the state government, the surcharge can be kept with CFI, and it can be utilised for other taxes.
    • However, cess should be utilised for a particular reason. This restricts the states expenditure.
    • Tamil Nadu noted that the share of cesses and surcharges had grown from 10.4% of gross tax revenue in 2011-12 to 26.7% in 2021-22.
    • This has deprived the States of their legitimate share of revenue collected by the Union Government.

  • Rationalization in long-term Capital Gains Tax structure on the anvil

    The Finance Ministry is looking at rationalizing long-term capital gains tax structure by bringing parity between similar asset classes and revising the base year for computing indexation benefits.

    What is Capital Gains Tax?

    • Capital gains tax is levied on the profits made on investments (Base Year: 2001).
    • It covers real estate, gold, stocks, mutual funds, and various other financial and non-financial assets.
    • Under the Income Tax Act, gains from sale of capital assets — both movable and immovable — are subject to ‘capital gains tax’.

    Types of CGT

    (A) STCG (Short-term capital asset)

    • An asset held for a period of 36 months or less is a short-term capital asset.
    • The criteria is 24 months for immovable properties such as land, building and house property from FY 2017-18.
    • For instance, if you sell house property after holding it for a period of 24 months, any income arising will be treated as a long-term capital gain, provided that property is sold after 31st March 2017.
    • The reduced period of the aforementioned 24 months is not applicable to movable property such as jewellery, debt-oriented mutual funds etc.

    Some assets are considered short-term capital assets when these are held for 12 months or less. This rule is applicable if the date of transfer is after 10th July 2014 (irrespective of what the date of purchase is). These assets are:

    1. Equity or preference shares in a company listed on a recognized stock exchange in India
    2. Securities (like debentures, bonds, govt securities etc.) listed on a recognized stock exchange in India
    3. Units of UTI, whether quoted or not
    4. Units of equity oriented mutual fund, whether quoted or not
    5. Zero coupon bonds, whether quoted or not

    (B)  LTCG (Long-term capital asset )

    • An asset held for more than 36 months is a long-term capital asset.
    • They will be classified as a long-term capital asset if held for more than 36 months as earlier.
    • Capital assets such as land, building and house property shall be considered as long-term capital asset if the owner holds it for a period of 24 months or more (from FY 2017-18).

    Whereas, below-listed assets if held for a period of more than 12 months, shall be considered as long-term capital asset.

    1. Equity or preference shares in a company listed on a recognized stock exchange in India
    2. Securities (like debentures, bonds, govt securities etc.) listed on a recognized stock exchange in India
    3. Units of UTI, whether quoted or not
    4. Units of equity oriented mutual fund, whether quoted or not
    5. Zero coupon bonds, whether quoted or not

    Why is it so complicated?

    Capital gains tax is complicated for a few primary reasons.

    • First, the rate changes from asset to asset. LTCG tax on stocks and equity mutual funds is 10% but on debt mutual funds is 20% with indexation.
    • Second, holding period changes from asset to asset. The holding period for LTCG tax is two years in real estate, one year for stocks, and three years for debt mutual funds and gold.
    • Third, exemptions available against it come with their own complex conditions. For instance, buying a house after selling one can get you an exemption, but the new house must be bought in two years or built in three years of the sale.

    Stipulated reforms by Finance Ministry

    • Currently, shares held for more than one year attract a 10% tax on long-term capital gains.
    • Gains arising from sale of immovable property and unlisted shares held for more than 2 years and debt instruments and jewellery held for over 3 years attract 20% long-term capital gains tax.
    • Also, a change in base year for computing inflation-adjusted capital gains is being contemplated.
    • The index year for capital gains tax calculation is revised periodically to make it more relevant. The last revision took place in 2017 when the base year was updated to 2001.
    • Since the prices of assets increase over time, the indexation is used to arrive at the inflation-adjusted purchasing price of assets to compute long-term capital gains for the purpose of taxation.

  • Russia offers advanced nuclear fuel for Kudankulam Reactor

    The Russian state-owned nuclear energy corporation Rosatom has offered a more advanced fuel option to India’s largest nuclear power station at Kudankulam, which will allow its reactors to run for an extended 2-year cycle without stopping to load fresh fuel.

    What is the news?

    • Rosatom’s nuclear fuel division, TVEL Fuel Company, is the current supplier of TVS – 2 M fuel for the two VVER 1,000 MWe reactors generating power in the Kudankulam Nuclear Power Project (KKNPP).
    • This fuel has an 18-month fuel cycle, meaning that the reactor has to be stopped for fresh fuel loading every one-and-a-half years.
    • TVEL has now offered the more modern Advanced Technology Fuel (ATF), whose fuel cycle is a whopping 24 months.

    Benefits of the move

    • This fuel will ensure more efficiency and additional power generation due to the prolonged operation of the reactor.
    • It will result in sizable savings of the foreign exchange need to buy fresh fuel assemblies from Russia.

    What is the Nuclear Fuel Cycle?

    • The nuclear fuel cycle consists of front-end steps that prepare uranium for use in nuclear reactors and back-end steps to safely manage, prepare, and dispose of used—or spent—but still highly radioactive spent nuclear fuel.
    • Uranium is the most widely used fuel by nuclear power plants for nuclear fission.
    • Nuclear power plants use a certain type of uranium—U-235—as fuel because its atoms are easily split apart.
    • Although uranium is about 100 times more common than silver, U-235 is relatively rare at just over 0.7% of natural uranium.

    Steps involved in fuel enrichment

    • Uranium concentrate is separated from uranium ore at uranium mills or from a slurry at in-situ leaching facilities.
    • It is then processed in conversion and enrichment facilities, which increases the level of U-235 to 3%–5% for commercial nuclear reactors, and made into reactor fuel pellets and fuel rods in reactor fuel fabrication plants.
    • Nuclear fuel is loaded into reactors and used until the fuel assemblies become highly radioactive and must be removed for temporary storage and eventual disposal.
    • Chemical processing of spent fuel material to recover any remaining product that could undergo fission again in a new fuel assembly is technically feasible.

    Back2Basics: Uranium Enrichment

    • It is a process that is necessary to create an effective nuclear fuel out of mined uranium.
    • It involves increasing the percentage of uranium-235 which undergoes fission with thermal neutrons.
    • Nuclear fuel is mined from naturally occurring uranium ore deposits and then isolated through chemical reactions and separation processes.
    • These chemical processes used to separate the uranium from the ore are not to be confused with the physical and chemical processes used to enrich the uranium.

    Why is enrichment carried out?

    • Uranium found in nature consists largely of two isotopes, U-235 and U-238.
    • Natural uranium contains 0.7% of the U-235 isotope.
    • The remaining 99.3% is mostly the U-238 isotope which does not contribute directly to the fission process (though it does so indirectly by the formation of fissile isotopes of plutonium).
    • The production of energy in nuclear reactors is from the ‘fission’ or splitting of the U-235 atoms since it is the main fissile isotope of uranium.
    • Naturally occurring uranium does not have a high enough concentration of Uranium-235 at only about 0.72% with the remainder being Uranium-238.

  • Supreme Court launches online RTI Portal

    The Supreme Court has launched an online portal that will help citizens file and access applications under the Right to Information (RTI) Act in matters related to the court

    What is the online RTI portal?

    • The online RTI portal has been initiated to make it convenient for people to access information about the Supreme Court.
    • So far, RTI applications at the Supreme Court had to be filed only via post.
    • Various public interest litigation (PILs) had been filed before the Supreme Court seeking an online RTI portal for the Court.
    • The online portal is likely to streamline responses of the Supreme Court under the Right to Information Act.

    How does the online portal work?

    • The online portal can be accessed at a dedicated url.
    • Essentially, the process of filing an RTI in the Supreme Court is the same as how one normally files the application.
    • This web portal can be used only by Indian citizens to file RTI applications, first appeals and to make payment for fees, and copying charges, under the Right to Information Act, 2005 (RTI Act).
    • An applicant must first register themselves in the web portal.

    Fees prescribed

    • The applicant can pay the prescribed fee through internet banking, credit/debit card of Master/Visa or UPI.
    • The fee per RTI application is ₹10.
    • Any applicant who is Below Poverty Line (BPL) is exempted to pay the application fee under the RTI Rules, 2012.

    Expected time for response

    • By law, RTIs must be replied to within 30 days.
    • In fact, in life and death cases, RTIs must be responded to within 48 hours.

    Back2Basics: Right to Information

    • RTI is an act of the parliament which sets out the rules and procedures regarding citizens’ right to information.
    • It replaced the former Freedom of Information Act, 2002.
    • Under the provisions of RTI Act, any citizen of India may request information from a “public authority” (a body of Government or “instrumentality of State”) which is required to reply expeditiously or within 30.
    • In case of the matter involving a petitioner’s life and liberty, the information has to be provided within 48 hours.
    • The Act also requires every public authority to computerize their records for wide dissemination and to proactively publish certain categories of information so that the citizens need minimum recourse to request for information formally.

  • GST on Online Gaming, Casinos, Racing

    A ministerial panel is likely to recommend a uniform 28 percent tax GST rate on Online Gaming, irrespective of whether it is a game of skill or chance.

    Online gaming sector in India

    • In the past few years, India’s nascent online gaming industry witnessed an unprecedented rise, catapulting it to the top five mobile gaming markets in the world.
    • Registering a growth rate of 38%, online gaming is the next sunrise industry.
    • Currently, there are more than 400 gaming companies in India, and it is home to 420 million online gamers, second only to China, according to an analysis by KPMG.

    Types of gaming

    • The types of online gaming include:
    1. E-sports (well-organized electronic sports which include professional players) ex. Chess
    2. Fantasy sports (choosing real-life sports players and winning points based on players’ performance) ex. MPL cricket
    3. Skill-based (mental skill) ex. Archery
    4. Gamble (based on random activity) ex. Playing Cards, Rummy

    Why is the gaming industry booming in India?

    1. Digital India boom in the gaming industry
    2. Narrowing of the digital divide
    3. IT boom

    Other factors promoting the boom

    1. Growing younger population
    2. Higher disposable income
    3. Inexpensive internet data
    4. Introduction of new gaming genres, and
    5. Increasing number of smartphone and tablet users

    Prospects of online gaming

    • State List Subject:  The state legislators are, vide Entry No. 34 of List II (State List) of the Seventh Schedule, given exclusive power to make laws relating to betting and gambling.
    • Distinction in laws: Most Indian states regulate gaming on the basis of a distinction in law between ‘games of skill’ and ‘games of chance’.
    • Classification on dominant element: As such, a ‘dominant element’ test is utilized to determine whether chance or skill is the dominating element in determining the result of the game.
    • Linked economic activity: Staking money or property on the outcome of a ‘game of chance’ is prohibited and subjects the guilty parties to criminal sanctions.
    • ‘Game of Skill’ debate: Placing any stakes on the outcome of a ‘game of skill’ is not illegal per se and may be permissible. It is important to note that the Supreme Court recognized that no game is purely a ‘game of skill’ and almost all games have an element of chance.

    Need for regulation

    • No comprehensive regulation:  India currently has no comprehensive legislation with regards to the legality of online gaming or boundaries that specify applicable tax rates within the betting and gambling industry.
    • Ambiguity of the sector: The gaming sector is nascent and is still evolving, and many states are bringing about legislation seeking to bring about some order in the online gaming sector.
    • State list subject: Online gaming in India is allowed in most parts of the country. However, different states have their own legislation with regards to whether online gaming is permitted.
    • Economic advantage: Well-regulated online gaming has its own advantages, such as economic growth and employment benefits.

    Issues with online gaming

    • Gaming addiction: Numerous people are developing an addiction to online gaming. This is destroying lives and devastating families.
    • Compulsive gaming: Gaming by children is affecting their performance in schools and impacting their social lives & relationships with family members. Ex. PUBG
    • Impact on psychological health: Online games like PUBG and the Blue Whale Challenge were banned after incidents of violence and suicide.
    • Threat to Data privacy: Inadvertent sharing of personal information can lead to cases of cheating, privacy violations, abuse, and bullying.
    • Betting and gambling: Online games based on the traditional ludo, arguably the most popular online game in India, have run into controversy, and allegations of betting and gambling.

    Why hasn’t a comprehensive law yet materialized?

    • Earlier, states like Tamil Nadu, Telangana, Andhra Pradesh, and Karnataka also passed laws banning online games.
    • However, they were quashed by state High Courts on grounds that an outright ban was unfair to games of skill:
    1. Violation of fundamental rights of trade and commerce, liberty and privacy, speech and expression;
    2. Law being manifestly arbitrary and irrational insofar as it did not distinguish between two different categories of games, i.e. games of skill and chance;
    3. Lack of legislative Competence of State legislatures to enact laws on online skill-based games.

    Way forward

    • Censoring: Minors should be allowed to proceed only with the consent of their parents — OTP verification on Aadhaar could resolve this.
    • Awareness: Gaming companies should proactively educate users about potential risks and how to identify likely situations of cheating and abuse.
    • Regulating mechanism: A Gaming Authority in the central government should be created.
    • Accountability of the gaming company: It could be made responsible for the online gaming industry, monitoring its operations, preventing societal issues, suitably classifying games of skill or chance, overseeing consumer protection, and combatting illegality and crime.
    • All-encompassing legislation: the Centre should formulate an overarching regulatory framework for online games of skill. India must move beyond skill-versus-chance debates to keep up with the global gaming industry.

  • Buddhist Nyingma Sect finds ‘reincarnation’ of famous Rinpoche

    In a significant development in Tibetan Buddhist circles, the Nyingma sect has identified a boy from Spiti in Himachal Pradesh as the reincarnation of the late Taklung Setrung Rinpoche, a scholar known for his knowledge of Tibetan Tantric school.

    About the Nyingma Sect

    • Nyingma (literally ‘old school’) is the oldest of the four major schools of Tibetan Buddhism.
    • It is founded on the first lineages and translations of Buddhist scriptures from Sanskrit into Tibetan in the eighth century, during the reign of King Trisong Detsen (r. 710–755).
    • Nyingma traditional histories consider their teachings to trace back to the first Buddha Samantabhadra (Güntu Sangpo) and Indian mahasiddhas such as Garab Dorjé, Śrī Siṃha and Jñānasūtra.
    • Traditional sources trace the origin of the Nyingma order in Tibet to figures associated with the initial introduction of Buddhism in the 8th century, such as Padmasambhava, Yeshe Tsogyal, Vimalamitra, Vairotsana, Buddhaguhya and Shantaraksita.

    Who is a Rinpoche?

    • Rinpoche is an honorific term used in the Tibetan language.
    • It literally means “precious one”, and may refer to a person, place, or thing—like the words “gem” or “jewel”.
    • The word consists of rin (value), po (nominalizing suffix) and chen (big).
    • The word is used in the context of Tibetan Buddhism as a way of showing respect when addressing those recognized as reincarnated, older, respected or an accomplished Lamas or teachers of the Dharma.
    • It is also used as an honorific for abbots of Buddhist monasteries.

     Guru Tegh Bahadur (1621–1675)

    • Guru Tegh Bahadur was the ninth of ten Gurus of the Sikh religion. He was born at Amritsar in 1621 and was the youngest son of Guru Hargobind.
    • His term as Guru ran from 1665 to 1675. One hundred and fifteen of his hymns are in Guru Granth Sahib.
    • There are several accounts explaining the motive behind the assassination of Guru Tegh Bahadur on Aurangzeb’s orders.
    • He stood up for the rights of Kashmiri Pandits who approached him against religious persecution by Aurangzeb.
    • He was publicly executed in 1675 on the orders of Mughal emperor Aurangzeb in Delhi for himself refusing Mughal rulers and defying them.
    • Gurudwara Sis Ganj Sahib and Gurdwara Rakab Ganj Sahib in Delhi mark the places of execution and cremation of his body.

    Impact of his martyrdom

    • The execution hardened the resolve of Sikhs against religious oppression and persecution.
    • His martyrdom helped all Sikh Panths consolidate to make the protection of human rights central to its Sikh identity.
    • Inspired by him, his nine-year-old son, Guru Gobind Singh Ji, eventually organized the Sikh group into a distinct, formal, symbol-patterned community that came to be known as Khalsa (Martial) identity.
    • In the words of Noel King of the University of California, “Guru Teg Bahadur’s martyrdom was the first-ever martyrdom for human rights in the world.

  • India’s abstains in CITES vote on reopening Ivory Trade

    India’s decision not to vote against a proposal to re-open the international trade in ivory at the ongoing conference of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).

    What is CITES?

    • CITES stands for the Convention on International Trade in Endangered Species of Wild Fauna and Flora.
    • It is as an international agreement aimed at ensuring “that international trade in specimens of wild animals and plants does not threaten their survival”.
    • It was drafted after a resolution was adopted at a meeting of the members of the International Union for Conservation of Nature (IUCN) in 1963.
    • It entered into force on July 1, 1975, and now has 183 parties.
    • The Convention is legally binding on the Parties in the sense that they are committed to implementing it; however, it does not take the place of national laws.
    • India is a signatory to and has also ratified CITES convention in 1976.

    CITES Appendices

    • CITES works by subjecting international trade in specimens of selected species to certain controls.
    • All import, export, re-exports and introduction from the sea of species covered by the convention has to be authorized through a licensing system.

    It has three appendices:

    • Appendix I includes species threatened with extinction. Trade-in specimens of these species are permitted only in exceptional circumstances.
    • Appendix II provides a lower level of protection.
    • Appendix III contains species that are protected in at least one country, which has asked other CITES Parties for assistance in controlling trade.

    What is the news?

    • India remained absent during the CITES conference aimed to re-open the international trade in ivory.

    Why such move by India?

    • Elephant remains one of India’s most powerful cultural and religious symbols.
    • A pioneer in banning even the domestic trade in ivory in 1986, India has always been at the forefront of global elephant conservation initiatives.

    What is the tussle over Ivory?

    • The international ivory trade was globally banned in 1989 when all African elephant populations were put in CITES Appendix I.
    • However, the populations of Namibia, Botswana, and Zimbabwe were transferred to Appendix II in 1997, and South Africa’s in 2000 to allow two “one-off sales”.
    • This is because ivory stockpiled from natural elephant deaths and seizures from poachers.
    • Subsequently, Namibia’s proposal for allowing a regular form of controlled trade in ivory by delisting the elephant populations of the four countries from Appendix II was rejected at CoP17 (2016) and CoP18 (2019).
    • At the ongoing CoP19, the proposal was moved by Zimbabwe but met the same fate.
    • These are low income countries often battling to generate some revenue from Ivory trade.

    India and ivory trade

    • The endangered Asian elephant was included in CITES Appendix I in 1975, which banned the export of ivory from the Asian range countries.
    • In 1986, India amended The Wild Life (Protection) Act, 1972 to ban even domestic sales of ivory.
    • After the ivory trade was globally banned, India again amended the law to ban the import of African ivory in 1991.
    • In 1981 when New Delhi hosted COP3, India designed the iconic CITES logo in the form of an elephant.
    • Over the years, India’s stand has been unequivocal on the ivory issue.

    What has changed now?

    • After protracted negotiation, India signed an agreement in July with Namibia to fly in cheetahs.
    • India has agreed to promote “sustainable utilisation and management of biodiversity” by supporting advances in this area of bilateral cooperation “at international forums including meetings of” CITES.
    • While the word “ivory” was not mentioned, Namibia sought India’s support under this agreement.

  • ISRO to attempt 200th consecutively successful launch of RH-200 sounding rocket

    rh-200

    The Indian Space Research Organisation (ISRO) has attempted the 200th consecutively successful launch of the Rohini RH-200 sounding rocket from Thumba.

    RH-200 (Rohini )

    • RH-200 is a two-stage rocket capable of climbing to a height of 70 km bearing scientific payloads.
    • The first and second stages of RH-200 are powered by solid motors. The ‘200’ in the name denotes the diameter of the rocket in mm.
    • Other operational Rohini variants are RH-300 Mk-II and RH-560 Mk-III.
    • For years, the RH-200 rocket had used a polyvinyl chloride (PVC)-based propellant.
    • The first RH-200 to use a new propellant based on hydroxyl-terminated Polybutadiene (HTPB) was successfully flown from the TERLS in September 2020.
    • The first and second stages of RH200 rocket are powered by solid motors.
    • Since inception of RH200 rocket, both solid stages are processed using polyvinyl chloride (PVC) based propellant.
    • As compared to PVC based propellants, HTPB based propellant is more energetic, higher mechanical & interface properties and has less defects due to lower processing temperature.

    What basically is a Sounding Rocket?

    • A sounding rocket is an instrument-carrying rocket designed to take measurements and perform scientific experiments during its sub-orbital flight.
    • The rockets are used to launch instruments from 48 to 145 km above the surface of the Earth, the altitude generally between weather balloons and satellites.
    • The maximum altitude for balloons is about 40 km and the minimum for satellites is approximately 121 km.

    History of sounding rockets in India

    • Sounding rockets have an important place in the ISRO story.
    • The first sounding rocket to be launched from Thumba was the American Nike-Apache — on November 21, 1963.
