Question 1

What is GST?

Accepted Answer

GST (Goods and Services Tax) is a comprehensive indirect tax levied on the supply of goods and services in India, introduced on 1 July 2017. It replaced multiple taxes including VAT, service tax, and excise duty. GST is charged at multiple rates: 0%, 3%, 5%, 12%, 18%, and 28%.

Question 2

What is the difference between GST exclusive and GST inclusive?

Accepted Answer

GST exclusive (Add GST) means the entered amount is the base price before tax — the calculator adds GST on top. GST inclusive (Remove GST) means the entered amount already includes GST — the calculator extracts the original base price and the tax portion.

Question 3

What are CGST and SGST?

Accepted Answer

For intra-state supplies, GST is split equally into CGST (Central GST, collected by the Centre) and SGST (State GST, collected by the state). Each is levied at half the applicable GST rate. For example, at 18% GST: CGST = 9% and SGST = 9%. For inter-state supplies, a single IGST (Integrated GST) at the full rate applies instead.

Question 4

What are the standard GST rates in India?

Accepted Answer

As per the GST Council: 0% (exempted goods — milk, eggs, fresh vegetables), 3% (gold, silver, precious metals), 5% (essential goods, transport services), 12% (processed foods, computers, medicines), 18% (most goods and services, electronics — the standard rate), and 28% (luxury goods, automobiles, tobacco, aerated beverages).

Question 5

How is GST calculated on an inclusive price?

Accepted Answer

For an amount that already includes GST, the original price = Total × 100 ÷ (100 + GST Rate), as per CGST Rules 2017, Rule 35. For example, ₹1,180 inclusive at 18% GST: Original = 1180 × 100 ÷ 118 = ₹1,000, and GST = ₹1,180 − ₹1,000 = ₹180.
