When the product is sold from Surat to Ahmedabad (It is an intra-state transaction).
For the Dealer in Surat, SP = ₹5000
CGST = SGST = 6% of ₹5000 = ₹300 [1 Mark]
When the product is sold from Ahmedabad to Jaipur(It is an Inter-state transaction).
For the Dealer in Ahmedabad :
Input Tax Credit(ITC) = ₹300 + ₹300 = ₹600
CP = ₹5000.
Profit = ₹1000.
SP = CP + Profit = ₹5000 + ₹1000 = ₹6000 [1 Mark]
IGST = 12% of ₹6000 = 12100×6000 = ₹720
∴ Net GST payable at Ahmedabad = Output Tax - ITC
= ₹720 - ₹600 = ₹120. [1 Mark]
