Understanding GST in India

Goods and Services Tax (GST) was implemented in India on July 1, 2017, replacing multiple indirect taxes. Here's what you need to know:

  • GST Structure: GST in India follows a dual structure where both the Centre and States levy tax on the supply of goods and services.
  • CGST & SGST: For intra-state transactions (within the same state), Central GST (CGST) and State GST (SGST) are applicable, each at half of the total GST rate.
  • IGST: For inter-state transactions (between different states), Integrated GST (IGST) is applicable at the full GST rate.
  • GST Rates: The main GST slabs in India are 0%, 5%, 12%, 18%, and 28%, with some special rates for specific items.

Frequently Asked Questions

What is GST and why is it important?

GST (Goods and Services Tax) is a comprehensive indirect tax levied on the supply of goods and services in India. It replaced multiple taxes like VAT, Service Tax, Excise Duty, etc. GST is important because it simplified the tax structure, eliminated the cascading effect of taxes, reduced compliance costs, and created a unified national market.

What is the difference between CGST, SGST, and IGST?

For transactions within the same state (intra-state), GST is divided equally between Central GST (CGST) and State GST (SGST). For example, if the GST rate is 18%, then 9% is collected as CGST and 9% as SGST.

For transactions between different states (inter-state), Integrated GST (IGST) is applicable at the full rate. Using the same example, the entire 18% would be collected as IGST.

How do I calculate GST on a product or service?

To calculate GST on a product or service:

  1. For GST exclusive calculation: Multiply the base amount by the GST rate percentage. For example, for an item costing ₹1,000 with 18% GST: GST amount = ₹1,000 × 18% = ₹180. Total amount = ₹1,000 + ₹180 = ₹1,180.
  2. For GST inclusive calculation: Divide the total amount by (100 + GST rate) and multiply by 100 to get the base amount. For example, if the total amount is ₹1,180 with 18% GST: Base amount = ₹1,180 × 100 ÷ 118 = ₹1,000. GST amount = ₹1,180 - ₹1,000 = ₹180.
What are the current GST rates in India?

The main GST slabs in India are:

  • 0%: Essential goods like fresh fruits, vegetables, milk, etc.
  • 5%: Essential items like packaged food items, transport services, etc.
  • 12%: Standard rate for items like processed food, business class air tickets, etc.
  • 18%: Standard rate for most goods and services including electronics, telecom, etc.
  • 28%: Luxury items and sin goods like luxury cars, tobacco products, etc.

There are also special rates like 0.25%, 1%, and 3% for specific items like rough precious stones, affordable housing, etc.

How do I find the original price when I only know the final price with GST?

To find the original price (before GST) when you only know the final price:

  1. Use the formula: Original Price = Final Price × 100 ÷ (100 + GST Rate)
  2. For example, if the final price is ₹1,180 with 18% GST: Original Price = ₹1,180 × 100 ÷ 118 = ₹1,000

You can use our "Reverse Calculation" tab to do this calculation automatically.

Do I need to register for GST?

You need to register for GST if:

  • Your aggregate turnover exceeds ₹20 lakhs (₹10 lakhs for special category states) in a financial year.
  • You make inter-state supplies (regardless of turnover).
  • You are a casual taxable person or a non-resident taxable person.
  • You are required to pay tax under reverse charge mechanism.
  • You are an e-commerce operator or supplier through an e-commerce platform.
  • You are an agent of a supplier.

Even if you're below the threshold, voluntary registration is possible and sometimes beneficial for claiming input tax credits.

What is Input Tax Credit (ITC) in GST?

Input Tax Credit (ITC) is a mechanism where businesses can claim credit for the GST paid on purchases used for business purposes. This helps eliminate the cascading effect of taxes (tax on tax).

For example, if a manufacturer pays ₹10,000 as GST on raw materials and collects ₹15,000 as GST on the final product, they only need to pay the difference of ₹5,000 to the government, claiming the ₹10,000 as ITC.

To claim ITC, businesses must have valid tax invoices, must have received the goods/services, and must have filed their GST returns.
