How It Works
Worked Example
A vendor in Surat supplies goods worth ₹10,000 to a buyer in Ahmedabad (intra-state Gujarat) at 18% GST. Total GST is ₹1,800, divided into ₹900 CGST and ₹900 SGST.
When to Use This
Mandatory when issuing GST-compliant tax invoices to customers located in the same state as your registered GSTIN.
Why Use This Tool?
Booking an intra-state transaction under IGST instead of CGST/SGST violates GST invoice rules and results in portal mismatches and notices under Section 77 of the CGST Act.
