Financial Planning Maths Notes

Observe the given bill and fill in the boxes with appropriate number:

  • CGST at the rate of 2.5 % is ₹ 5.00 and SGST at the rate of 2.5 % is ₹ 5.00.
  • It means that the rate of GST on Pedhe is (2.5 + 2.5) % = 5 %, and hence the total GST is 10.
  • The rate of GST on chocolate is 28 %, and hence the total GST is ₹ 22.40
  • The rate of GST on ice cream is 18 %, and hence the total cost of ice cream is ₹ 236.00
  • On butter, CGST rate is 6 % and SGST rate is also 6 %. So GST rate on butter is 12 %
  • The rate of CGST and SGST are the same. The rate of GST = The rate of CGST + The rate of SGST.

GST in trading chain :

Financial Planning Notes 4
Trading chain (Within state)

Let’s learn through an example how GST is charged and paid to the government at every stage of trading.

Illustration: Suppose manufacturer of a watch sold one watch for ₹ 200. (including profit) to the wholesaler. Wholesaler sold that watch for ₹ 300 to the retailer. Retailer sold it to the customer for ₹ 400. Rate of GST charged at every stage is 12 %. Then how each trader pays GST and takes his input tax credit (ITC) at every stage of transaction is shown in the following flow chart. Observe and study it.

Explanation: Here, three financial transactions took place till the watch from manufacturer reaches the customer. How the taxes are charged, collected and paid to the central government and state government at each stage is shown below. The statement of taxes paid is given in the table thereafter.

Let’s Remember:

Trading between GSTIN holders is known as Business to Business, in short B2B.

Trading between GSTIN holder and consumer is known as Business to Consumer, in short B2C. This is the last link in the trading chain.

GST is levied and collected at every stage of trading from manufacturer to consumer.

Input Tax Credit (ITC)

When a trader pays GST at the time of purchase, it is called ‘Input tax’.
When the trader collects GST at the time of sale, it is called ‘Output tax’.

Input Tax Credit = Output tax – Input tax
GST payable by the trader = Output tax – ITC

While paying taxes to the government, each trader in the trading chain subtracts the tax paid at the time of purchase from the tax collected at the time of sale and pays the remaining tax.

Let’s think

Suppose in the month of July the output tax of a trader is equal to the input tax, then what is his payable GST?
⇒ The trader’s payable GST is nil.
He has paid the input tax.
Output tax is the same as input tax
∴ the tax payable by the trader
= output tax – input tax = 0

Suppose in the month of July output tax of a trader is less than the input tax, then how to compute his GST?
⇒ When the output tax is less than the input tax, the trader will keep the output tax with him and the difference which is less will be carried forward for the next month.
