A dealer supplied electrical items worth ₹ 17,00,000 in interstate transactions and worth another ₹ 3,00,000 in transactions within the state. The total value of his receipts of goods in interstate transactions was ₹ 15,00,000. If the rate of GST is 18%, calculate the net IGST, CGST and SGST payable by the dealer.

Given,

GST Rate = 18%

For interstate transactions (IGST) = 18%

For intrastate transactions (CGST + SGST) = 18%, meaning CGST = 9% and SGST = 9%.

Input Tax Credit (ITC) from Receipts (Purchases):

The dealer's receipts (purchases) were in interstate transactions. This means the dealer paid IGST on these purchases.

Value of receipts (purchases) in interstate transactions : ₹ 15,00,000

IGST paid on receipts (Input IGST): 18% of ₹ 15,00,000

= $\dfrac{18}{100} \times 15,00,000$

= ₹ 2,70,000.

So, the dealer has an Input Tax Credit (ITC) of ₹ 2,70,000 (IGST).

Output Tax from Supplies (Sales):

The dealer has two types of outward supplies (sales):

Interstate Transactions (Sales):

Value of interstate supplies: ₹ 17,00,000

IGST charged on interstate supplies (Output IGST): 18% of ₹ 17,00,000

= $\dfrac{18}{100} \times 17,00,000$

= ₹ 3,06,000

Intrastate Transactions (Sales) :

Value of intrastate supplies : ₹ 3,00,000

CGST charged on intrastate supplies (Output CGST): 9% of ₹ 3,00,000

= $\dfrac{9}{100} \times 3,00,000$

= ₹ 27,000.

SGST charged on intrastate supplies (Output SGST): 9% of ₹ 3,00,000

= $\dfrac{9}{100} \times 3,00,000$

= ₹ 27,000.

Calculating Net GST Payable (Utilizing ITC):

We will utilize the available IGST ITC against the output tax liabilities. The order of utilization for IGST ITC is:

First against IGST liability, Then against CGST liability, Finally, against SGST liability.

Available ITC:

IGST ITC = ₹ 2,70,000

Output Tax Liabilities:

Output IGST = ₹ 3,06,000

Output CGST = ₹ 27,000

Output SGST = ₹ 27,000

ITC utilization :

Against Output IGST :

Output IGST liability = ₹ 3,06,000

IGST ITC available = ₹ 2,70,000

Use all available IGST ITC (₹ 2,70,000) against Output IGST.

Net IGST payable = ₹ 3,06,000 - ₹ 2,70,000 = ₹ 36,000

Remaining IGST ITC = ₹ 0 (all utilized)

Against Output CGST :

Output CGST liability = ₹ 27,000

Remaining IGST ITC = ₹ 0

Net CGST payable = ₹ 27,000 (since no IGST ITC is left to offset it, and there's no CGST ITC from purchases mentioned)

Against Output SGST :

Output SGST liability = ₹ 27,000

Remaining IGST ITC = ₹ 0

Net SGST payable = ₹ 27,000 (since no IGST ITC is left to offset it, and there's no SGST ITC from purchases mentioned)

Hence, Net IGST payable = ₹ 36,000, Net CGST payable = ₹ 27,000, Net SGST payable = ₹ 27,000.
