1.1.1. Key Concepts

● GST: An indirect tax levied on the supply of goods and services.

Goods and Services Tax (GST) is a tax that the government charges on the sale of goods and services. Since it is an indirect tax, it is not directly paid by the consumer but is included in the price of the goods or services you purchase. When you buy something, the seller adds GST to the price, and this tax is then collected by the government.

Think of GST like a toll on a road you drive on. Just as you pay a toll to use the road, you pay GST as part of the price for products and services. The seller collects this tax from you and passes it on to the government.

● CGST and SGST: Central GST and State GST – each charged at 50% of the total GST when goods/services are sold within a state.

When you purchase goods or services within a single state, the GST is split into two parts: Central GST (CGST) and State GST (SGST). Each part accounts for half of the total GST charged. This system allows the central government and the state government to collect taxes proportionally based on where the transaction occurs.

Imagine a pizza sold in your state for ₹100 with a 10% GST. Out of the total ₹10 GST, ₹5 goes to the central government (like funding national roads), and ₹5 goes to your state government (like funding your local schools).

● IGST: Integrated GST – charged on inter-state supply.

When goods or services are sold between different states, Integrated GST (IGST) is applicable. This tax combines the Central GST and State GST into one, so it can be applied to cross-border sales. IGST simplifies the taxation process across state lines, ensuring that the government receives its due share from both the origin and destination states of the goods or services.

Consider a company in Maharashtra selling its products to a buyer in Karnataka. Here, instead of separately accounting for CGST and SGST, IGST is applied. This way, the tax remains unified and ensures fair distribution of taxes between the states involved.

Formulas ● GST = Taxable Amount × GST Rate ● Final Price = Cost Price + GST

To calculate GST for any item, you multiply the taxable amount by the GST rate. Then, to determine the final price you pay, you add this GST to the cost price of the item. This helps you understand how much tax contributes to the final cost of goods or services.

If you buy a book for ₹200 and the GST rate is 5%, the GST you pay is ₹200 × 0.05 = ₹10. Therefore, your total payment for the book will be ₹200 + ₹10 = ₹210.

● Input Tax Credit (ITC): Credit received for tax paid on purchases.

Input Tax Credit allows businesses to deduct the GST they have already paid on their purchases from the GST they collect on sales. This feature is crucial for ensuring that businesses do not have to bear the tax burden on their inputs while paying taxes on their sales.

Imagine you're a baker. You buy flour and sugar, paying ₹100 in GST. When you sell cakes, you also collect ₹150 as GST from your customers. With ITC, you can subtract the ₹100 you paid from the ₹150 you collected, meaning you only pay the net GST of ₹50 to the government.

● Net GST Payable = Output GST – Input GST

The net GST payable is the total amount that a business needs to pay the government after accounting for GST they have collected from their customers (output GST) and the GST they have already paid on their purchases (input GST). This formula ensures that businesses only pay tax on their profit margins, not the entire sale price.

If a shopkeeper collects ₹2,700 as output GST from sales but has already paid ₹1,800 as input GST for goods purchased, the net GST payable to the government would be ₹2,700 - ₹1,800 = ₹900. It helps the shopkeeper track how much tax they actually owe.
