GST Full Form and Introduction
GST stands for "Goods and Services Tax". It is a comprehensive indirect tax that was introduced on July 1, 2017. GST replaced multiple taxes like VAT, Service Tax, and Excise Duty with a single unified tax system.
GST Rates Explained
There are 4 main GST tax slabs. Different products and services have different rates applied to them:
| GST Rate | Items/Services |
|---|---|
| 0% GST | Fresh vegetables, fruits, milk, eggs, bread, salt, books |
| 5% GST | Sugar, tea, coffee, edible oil, coal, medicines, economy class flight tickets |
| 12% GST | Butter, cheese, ghee, mobile phones, computers, processed food |
| 18% GST | Hair oil, toothpaste, soap, capital goods, industrial machinery, IT services |
| 28% GST | Luxury cars, pan masala, tobacco, aerated drinks, AC, washing machine |
Types of GST
There are three types of GST:
1. CGST (Central GST)
CGST is collected by the Central Government. When a transaction happens within the same state, half of the total GST goes as CGST.
2. SGST (State GST)
SGST goes to the State Government. In intra-state transactions, SGST is charged in equal amount along with CGST.
3. IGST (Integrated GST)
IGST applies to inter-state transactions. When goods or services move from one state to another, IGST is applied.
How to Calculate GST? (GST Calculation Formula)
There are two ways to calculate GST:
Method 1: Adding GST (Exclusive)
When you need to add GST to the original price:
Final Price = Original Price + GST Amount
Example: $1000 item with 18% GST
GST = (1000 × 18) / 100 = $180
Final Price = 1000 + 180 = $1180
Method 2: Removing GST (Inclusive)
When GST is already included in the price:
GST Amount = Total Price - Original Price
Example: $1180 with 18% GST included
Original = 1180 × (100/118) = $1000
GST Amount = 1180 - 1000 = $180
