Goods and Services Tax (GST) is India's unified indirect tax system. Registering for GST is mandatory for businesses exceeding turnover limits, engaging in inter-state supply, selling on e-commerce platforms (Amazon, Flipkart), or bidding for corporate tenders. Obtaining your 15-digit GSTIN (GST Identification Number) establishes business credibility and enables input tax credit (ITC) claims.

Mandatory Turnover Thresholds for GST

GST registration rules specify mandatory registration criteria:

  • **Goods Suppliers**: Mandatory registration if annual turnover exceeds ₹40 Lakhs (₹20 Lakhs for special category states).
  • **Service Providers**: Mandatory registration if annual turnover exceeds ₹20 Lakhs (₹10 Lakhs for special category states).
  • **Mandatory Cases (No Turnover Limit)**: Inter-state sellers, e-commerce vendors, casual taxable persons, and importers.
