Under Indian Goods and Services Tax (GST) laws:
• Intra-State Supply: If the Seller's State and Buyer's Place of Supply (POS) are the same, GST is divided equally into CGST (Central GST) and SGST (State GST).
• Inter-State Supply: If the Seller's State and Place of Supply are different, IGST (Integrated GST) is applied as a single combined tax rate.
