GST (Goods and Services Tax) is an indirect tax levied on the supply of goods and services in India. It replaced multiple indirect taxes like VAT, service tax, and excise duty with a unified tax system.

What are the different GST rates in India?

India has multiple GST slabs: 0% (essential items), 5% (basic necessities), 12% (processed foods), 18% (most goods and services), and 28% (luxury items). Some items also have cess added.

How to calculate GST amount?

To add GST: GST Amount = (Original Price × GST Rate) / 100. Final Price = Original Price + GST Amount. To remove GST: Original Price = Final Price / (1 + GST Rate/100).

What is CGST and SGST?

For intra-state transactions, GST is split equally into CGST (Central GST) and SGST (State GST). For inter-state transactions, IGST (Integrated GST) is charged at the full rate.

Is GST included in MRP?

What is GST?

GST (Goods and Services Tax) is a comprehensive indirect tax levied on the manufacture, sale, and consumption of goods and services in India. Implemented on July 1, 2017, GST replaced multiple cascading taxes like VAT, service tax, excise duty, and others with a unified tax system.

GST is a destination-based tax, meaning it's collected at the point of consumption rather than the point of origin. This has simplified India's tax structure and made it easier for businesses to comply with tax regulations.

GST Rate Slabs in India

India has a multi-tier GST structure with different rates for different categories of goods and services:

GST Rate	Category	Examples
0%	Essential Items	Fresh vegetables, milk, bread, salt, educational services
5%	Basic Necessities	Sugar, tea, coffee, edible oils, domestic LPG, coal
12%	Processed Foods	Butter, ghee, packed food items, computers, mobile phones
18%	Most Goods & Services	Soaps, toothpaste, capital goods, industrial intermediaries, IT services
28%	Luxury Items	Cars, motorcycles, air conditioners, cigarettes, aerated drinks

How to Calculate GST

There are two common scenarios when calculating GST:

Adding GST to Base Price

When you have the base price and need to add GST:

GST Amount = (Base Price × GST Rate) / 100

Final Price = Base Price + GST Amount

Example: Base price = ₹1,000, GST = 18%

GST Amount = (1,000 × 18) / 100 = ₹180
Final Price = ₹1,000 + ₹180 = ₹1,180

Removing GST from Final Price

When you have the final price (including GST) and need to find the base price:

Base Price = Final Price / (1 + GST Rate/100)

GST Amount = Final Price - Base Price

Example: Final price = ₹1,180, GST = 18%

Base Price = 1,180 / (1 + 18/100) = 1,180 / 1.18 = ₹1,000
GST Amount = ₹1,180 - ₹1,000 = ₹180

Understanding CGST, SGST, and IGST

CGST (Central GST)

Tax collected by the Central Government on intra-state transactions. It's half of the total GST rate.

SGST (State GST)

Tax collected by the State Government on intra-state transactions. It's the other half of the total GST rate.

IGST (Integrated GST)

Tax collected by the Central Government on inter-state transactions. It's the full GST rate.

Example: For 18% GST on intra-state sale:

CGST = 9%
SGST = 9%
Total = 18%
