GST replaces a plethora of taxes such as Central Excise Duty, Service Tax, etc., administered and appropriated by the Central Government and State taxes like VAT, CST, Entry Tax, etc. Presently, the Centre does not have power to tax on trading, and the States do not have power to collect Service Tax. A 22nd Constitution Amendment Bill has been introduced in Parliament and has already been passed in lok Sabha which empowers the States to tax services and the Centre to tax on trading. Article 246A of the Bill empowers the States to make State GST law and the Union to make Central GST law, and Parliament has exclusive power to make law with respect to inter-State transactions.
