This report examines the economic impact of the Goods and Services Tax (GST) on electric vehicles (EVs) and sustainable business practices in India. It begins by explaining the basics of GST, its rates, and the context of the discussion, focusing on the proposed reduction of GST on batteries from 28% to 5%. The analysis utilizes a supply and demand diagram to illustrate the effects of GST on battery prices, consumer and producer surplus, and deadweight loss. The report then discusses the government's promotion of EVs for sustainability, highlighting the cost implications of high battery prices due to GST. It further compares the effects of GST on EVs versus petrol and hybrid cars, noting the relatively inelastic price effects on petrol cars. Finally, the report discusses the government's initiatives to encourage EV usage by lowering GST rates, while also considering expert opinions on the potential benefits of waiving taxes on batteries and EVs for an initial period to boost market growth and consumer adoption. The report concludes by emphasizing the importance of government policies in promoting sustainable practices and the transition to EVs.
