How GST addition, extraction & place of supply work
Adding GST (Exclusive to Inclusive): When your quoted price is exclusive of tax, GST Amount = Base Price × (GST Rate ÷ 100), and Total Invoice Value = Base Price + GST Amount.
Removing GST (Inclusive to Exclusive): When an MRP or receipt already includes GST, the taxable base is Base Price = Inclusive Amount ÷ (1 + GST Rate ÷ 100), and the embedded GST is Inclusive Amount − Base Price.
Intra-state vs. Inter-state Supply: When the supplier’s registration state and the place of supply are in the same state/UT, GST is split equally into Central GST (CGST) and State/UT GST (SGST/UTGST). When the supply is across two states, integrated tax (IGST) is charged at the full rate.
