What is IGST? 

IGST is applied by the central government on trade carried between two states, as well as imports/exports. The revenue is shared between the central and state governments where the trade takes place. 

What is CGST? Explained with Example

Let’s consider a Textile manufacturer in Surat selling sarees within Gujarat. In this case, the trade applies both CGST and SGST. Suppose he sold a stock of bandhani sarees to a retailer for ₹50,000, which applies to an 18% rate under GST 2.0. 

So, total GST applied is 18% x ₹50,000 = ₹9,000 

Where CGST is half the total GST rate = 9% = ₹4,500 

The manufacturer collects the amount from the retailer who recovers it from the buyer and then the amount is paid to the central government.

5%	2.5%	Daily use items like household goods, agricultural produce, etc.
18%	9%	Generic goods and services, industrial and consumer goods
40%	20%	Luxury brands, sin products, and aerated drinks.

What is the Formula to Compute the Central Goods and Services Tax (CGST)? 

The formula to compute CGST is: 

CGST = (CGST rate/100) X Taxable Amount 

Considering taxable Amount = ₹10,000

CGST = (9/100) x ₹10,000 = ₹900
