What is GST?

The Goods and Services Tax (GST) is an indirect tax imposed on the supply of goods and services in India. GST is a comprehensive, multi-stage tax imposed on any value addition, based on destination. On 1 July 2017, GST came into force and replaced much of the country’s indirect taxes. Goods and services under GST are divided into five different tax rates: 0%, 5%, 12%, 18% and 28%. However, certain goods are not taxed under GST, such as petroleum products, alcoholic beverages, and electricity. As per the previous tax, regime these goods are taxed separately by the individual state governments.

GST calculation Example (Calculation of Tax under GST)

Following is a simple illustration for GST Calculation

ParticularsRate (%)Amount
Invoice value12%200,000
Price to be charged on the Invoice12%224,000

GST calculation by Manufacturers:

ParticularsRate (%)Amount Pre-GSTAmount under GST
Cost of the product-200,000200,000
Excise Duty12.50%27,500Nil
Final Invoice to the wholesaler-278,438246,400

The manufacturer saves Rs.160 for 1000 points, i.e., 16% cost savings due to tax changes. There is a cost deduction for producers, who pass this benefit to wholesalers, retailers, and end-consumers along the supply chain.

Calculation of GST by Wholesalers & Retailers:

ParticularsRate (%)Amount Pre-GSTAmount under GST
Cost of the product-278,438246,400
VAT (Rs. 306282 x 12.5%) - (Credit on VAT paid above Rs. 30,938)12.50%7,347Nil
CGST (Rs. 271040 x 6%) - (Credit on CGST paid above Rs.13,200)6%Nil3,062
SGST (Rs. 271040 x 6%) - (Credit on SGST paid above Rs.13,200)6%Nil3,062
Final Invoice to the end-consumer-313,629277,164

The cost of the commodity falls due under the GST scheme and a cheaper price for the products must be charged by the end customer at the same profit margin received by wholesalers and distributors.

What is GST Inclusive amount?

The GST inclusive amount applies to the overall value of the product after the original value of the product is included in the GST amount. The tax shall not be paid separately concerning the consumer.

GST exclusive amount refers to the value of the commodity after subtracting the GST amount from the GST Inclusive value of the commodity.

Impact on Product Pricing of GST

Central and state governments are referred to as Central GST (CGST) and State GST (SGST) respectively, levying indirect taxes. The seller would charge the buyer taxes for intrastate transactions, such as CGST and SGST, to be paid to the central and state governments, respectively. An example of such a form of GST that demonstrates the effect of GST on product pricing is given below:

Old Tax SystemGST System
Price of a product sold from Kanpur to Bhopal = Rs.2,000Price of a product sold from Kanpur to Bhopal = Rs.2,000
VAT @ 10% = Rs.200CGST @ 5% = Rs.100 + SGST @ 5% = Rs.100
Cost of a product sold from Kanpur to Bhopal = Rs.2,200Cost of a product sold from Kanpur to Bhopal = Rs.2,200
Profit = Rs.2,000Profit = Rs.2,000
Selling Price = Rs.4,200Selling Price = Rs.4,200
CST @ 10% = Rs.420IGST @ 10% = Rs.420
Total cost of the product = Rs.4,620Total cost of the product = Rs.4,420

GST Bills

The GST Bill is touted to be a landmark tax bill in India. To curb double-taxation and anomalies concerning the same, this Bill is being introduced. Four bills were approved on 29 March 2017. For the full implementation of this Bill, the government has set a deadline of 1 July 2017. A selection of goods and services would become cheaper and the pocket would be heavier for some. However, a multi-tier tax slab with four distinct tax rates of 5 percent, 12 percent, 18 percent, and 28 percent has been placed forward instead of the expected single tax slab. The rationale behind this multi-tier structure is that it is not possible to tax essential goods and services at the same rate as luxury goods and services.
