What is GST?

  • The Goods and Service Tax also called as GST was introduced in India as a form of indirect tax. It was first approved in the parliament on 29 March 2017 and was effectively implemented on 1 July 2017. GST superseded other forms of indirect taxes like excise duty VAT and other service taxes. In simple words all the goods and services in the market are subject to GST.

  • All the value added systems in India fall under multistage goods and service tax law. This is completely dependent on the state and the type of trade. The whole nation is under GST. Each and every point of sale is taxed under the GST system. Sales that take place inside one state are subject to both central and state sales taxes. The Integrated GST is liable for all interstate sales.

  • CGST, SGST, and IGST are the three sub components under GST. Out of the three, CGST is collected by the central government in case of intrastate sale. SGST is collected by the state government for internal commodity exchanges. The federal government collects inter state transactions in the name of IGST.

Formula for intra-state GST taxes

GST may be computed using the formulas below in the case of intrastate transactions.

CGST = applicable GST rate/2

If the GST rate is 28 %, then (28/2 =14 % ) this 14% is CGST.
SGST/UTGST = applicable GST rate / 2.

CGST + SGST / UTGST = Applicable GST Rate

Examples of Understanding GST Calculation

Intrastate GST calculation

For instance, assume that a dealer in chennai transferred products worth ₹50,000 to a dealer in andhra. The single type of tax, the IGST, is included in the 18% tax rate. The merchant must charge IGST of ₹9,000 in this situation. The central government will get these funds.

Interstate GST calculation

A Gujarati customer purchases products from the same merchant for ₹50,000. Goods are subject to a 12 % GST. This percentage includes both CGST and SGST, each at 6%.
Since the sale is within the state the dealer was required to collect ₹6,000 in GST of which ₹3,000 will be collected by the federal government and ₹3,000 to the state government.

Calculation of GST by Wholesale and Retailers

The GST is calculated by retailers based on the GST service rate. For instance let's take an invoice value of ₹20000. If the GST rate is around 12% . Then the total price charged by the retailer will be around ₹22400.

  • 20000×12/100=22400
