Goods and Services Tax (GST) is a comprehensive indirect tax levied on the supply of goods and services in India. Implemented on July 1st, 2017, GST replaced multiple indirect taxes and unified the Indian tax system. As a consumption-based tax, GST is applied at each point of sale in the supply chain.

GST Registration Requirements

Businesses must register under GST if they meet the following criteria:
Supply TypeAnnual Turnover Threshold
Goods₹40 Lakhs
Services₹20 Lakhs
Businesses operating in special category states have lower thresholds: ₹20 Lakhs for goods and ₹10 Lakhs for services.

The GST Compliance Challenge

Managing GST compliance is complex and time-consuming. Businesses must:
  • Generate GST-compliant invoices with proper tax calculations
  • File monthly and annual returns (GSTR-1, GSTR-3B, GSTR-9)
  • Reconcile purchase and sales ledgers with supplier data
  • Claim Input Tax Credit (ITC) accurately
  • Generate E-Invoices for B2B transactions (mandatory for businesses with turnover > ₹5 Crores)
  • Create E-Way Bills for goods movement exceeding ₹50,000
  • Maintain accurate ledgers (Cash, ITC, Liability)
  • Track return filing status and deadlines
Non-compliance can result in interest, penalties, and operational disruptions.
