📖 Introduction: Why GST Registration is Not Optional — It’s Foundational
In today’s India, if you’re doing business — whether selling online, providing services, operating across states, or even earning beyond a certain threshold — GST Registration is not just a tax requirement… it’s a legal obligation.
The Goods and Services Tax (GST) system was implemented in 2017 as a revolutionary reform to:
- Replace multiple indirect taxes (VAT, Service Tax, Excise, etc.)
- Streamline tax reporting
- Bring transparency and uniformity
- Eliminate cascading tax
Under the CGST Act, 2017 and related State/UT laws, every eligible business must obtain GST registration to legally collect tax and claim input credit.
