Goods and Services Tax, or GST, was implemented in India on 1st July, 2017. It is an all-in-one tax that combines both the state and central taxes. GST has since then been made mandatory to all Indian service providers, business entities, producers and manufactures once their supply turnover crosses INR 20,00,000. GST is to be charged at every step of the supply chain with complete set-off benefits available.
