Goods and Services Tax (GST) is an indirect tax (or consumption tax) used in India on the supply of goods and services. Goods and services are divided into five different tax slabs for collection of tax - 0%, 5%, 12%, 18% and 28%.
It is a comprehensive, multistage, destination-based tax: comprehensive because it has subsumed almost all the indirect taxes except a few state taxes. Multi-staged as it is, the GST is imposed at every step in the production process, but is meant to be refunded to all parties in the various stages of production other than the final consumer and as a destination-based tax, it is collected from point of consumption and not point of origin like previous taxes.
Pre-GST, the statutory tax rate for most goods was about 26.5%, Post-GST, most goods are expected to be in the 18% tax range. The tax came into effect from 1 July 2017 through the implementation of the One Hundred and First Amendment of the Constitution of India by the Indian government. The GST replaced existing multiple taxes levied by the central and state governments.
