India's Unified Tax System

    GST Registration & Filing

    Everything you need to know about Goods and Services Tax — registration, return filing, compliance, and how Udyog360 automates it all.

    What is GST?

    Goods and Services Tax (GST) is a comprehensive, multi-stage, destination-based indirect tax levied on every value addition in the supply chain. It was introduced on 1st July 2017, replacing multiple indirect taxes such as VAT, Service Tax, Central Excise, CST, and others.

    GST is governed by the Central Goods and Services Tax Act, 2017 (CGST Act), respective State Goods and Services Tax Acts (SGST Acts), and the Integrated Goods and Services Tax Act, 2017 (IGST Act). It is administered through the GST Network (GSTN) portal at gst.gov.in.

    GST Structure: CGST (Central) + SGST (State) for intra-state supplies. IGST (Integrated) for inter-state supplies. Current rates: 0%, 5%, 12%, 18%, and 28% depending on the goods/services.
