The product GST rate is 5 % which means the government net GST collection from the product sold to the end customer is 5 % on Rs.120 taxable value, which works out to Rs.6.

But these 6 Rs will not be collected fully collected from the final supplier at every point of sale tax is collected at value addition, in our case let us assume the inputs of Hindustan Unilever for production is 0%.

Hindustan Unilever sells at Rs.105 including tax of Rs.5 GST from the super distributor and pays 5 Rs GST to the government as there is no input tax credit available and issues invoice mentioning GST as Rs.5. The super distributor sells at Rs.110.25 including tax of Rs.5.25 and pays tax of Rs.0.25 to the government after deducting tax already paid to Hindustan Unilever, similarly distributor pays Rs.0.25, supermarket pays Rs.0.50, so the total tax collected by the government from all the four-person comes to Rs.6 which is 5 % of final taxable value.

In simple terms, the supplier pays GST at the rate calculated on the value addition made by him in our case value addition made by the super distributor is Rs.5 (105-100) so the net tax payable is 5 % on Rs.5 which works out to be Rs.0.25.

 SL. No Supplier Calculation Tax paid by the Supplier to Government
 1  Hindustan Unilever  100 * 5 %  Rs.5
 2  Super Distributor  (105-100)* 5 %  Rs.0.25

 4.  Supermarket  (120-110) * 5 %  Rs.0.50
