Calculating Tax for Inter-State Sales

The Central Government imposes Integrated GST (IGST) on products and services supplied between states. In the event of an interstate transaction, the importing state will get the IGST.

When goods were moved between two states under the previous tax structure, CST was levied in addition to VAT and excise taxes. The sole tax imposed under the GST system on products travelling across state boundaries is the IGST. Here’s an illustration to help you comprehend the IGST system:

Manufacturer Value Old Tax System GST System
Cost of goods Rs 1,00,000 Rs 1,00,000
VAT of 12.5% 12,500
IGST of 12% Rs12,000
CST 2% Rs 2,250
Total Value Rs.1,14,500 Rs.1,12,000

The indirect tax levied by the Central and State Governments is called Central GST (CGST) and State GST (SGST). The seller will impose taxes on the buyer in intrastate transactions, such as CGST and SGST, and should be paid to the state and central governments. An illustration of this kind of GST is shown below, illustrating how it affects goods prices:

Old Tax System GST System
Product price got sold from Nagpur to Hyderabad = Rs.1,000 Price of a product sold from Nagpur to Hyderabad = Rs.1,000
VAT @ 10% = Rs.100 CGST @ 5% = Rs.50 + SGST @ 5% = Rs.50
Cost of the product sold from Nagpur to Hyderabad = Rs.1,100 Product sold from Nagpur to Hyderabad = Rs.1,100
Profit Rs 1000 Profit Rs 1000
Selling Price Rs 2100 Selling Price Rs 2100

Benefits of GST

The government, when implementing GST on products and goods, was clear that it wanted to change the tax structure in India, especially for businesspeople. There were multiple taxes, which were brought into one name, GST. Some of the advantages are-

  • The new tax regime helps to maintain the worldwide standard tax system. Additionally, it facilitates open communication between the producer and the customer.
  • Eliminating double taxes on business goods is the primary goal of the GST implementation. It further encourages increasing competition in providing quality products and services to customers and contributing towards the nation’s GDP.
  • Tax reductions lower manufacturers’ manufacturing costs, which in turn boosts exporters’ competitiveness.
  • It is anticipated that market inflation, which is the most important concern, will decline after the GST is implemented.
  • There is also a belief that the tax liability will decline. A price decrease is anticipated since input tax can be offset by output tax.
