Here’s your UPSC Current Affairs knowledge nugget for today on the retrospective GST levy on online gaming verdict.(Relevance: Taxation is an important part of the UPSC CSE syllabus. Previously, UPSC has asked questions on various aspects of taxation in the Indian economy. Additionally, online gaming regulation has frequently been in the news; therefore, knowing about it becomes essential for the exam.)The Supreme Court on May 27 has upheld the constitutional validity of the government’s retrospective 28 per cent Goods and Services Tax (GST) levy on online gaming companies. The verdict effectively revives tax demands running into nearly Rs 2.5 lakh crore against gaming firms, fantasy sports platforms and casinos, and could well spell the end of the road for the online gaming sector, already reeling under a ban imposed by the government in 2025.In this context, let’s understand the key highlight of SC’s verdict, what retrospective taxation is, and the steps the government has taken to regulate online gaming in India. Key Takeaways:1. A bench comprising Justices JB Pardiwala and R Mahadevan dismissed petitions filed by several gaming companies and industry bodies challenging the GST regime and retrospective tax notices issued by authorities.2. The dispute centred around the gaming sector’s contention that the 28% GST on online gaming should apply only prospectively, from 1 October 2023, after the amendments approved by the GST Council came into effect. 3. However, the apex court sided with the government’s interpretation and treated the 2023 GST amendments as clarificatory, thereby allowing retrospective application for periods before October 1, 2023.Story continues below this adWhat is Retrospective taxation?1.
