Understanding GST in India

The Goods and Services Tax (GST) is an indirect tax levied on the supply of goods and services in India. Our GST Calculator helps you quickly calculate tax amounts for both inclusive and exclusive pricing scenarios.

GST Tax Slabs in India

• 0% GST: Essential commodities like fresh fruits, vegetables, milk, bread, eggs
• 5% GST: Household necessities like sugar, tea, coffee, edible oils, coal
• 12% GST: Processed foods, mobile phones (under ₹25,000), computers
• 18% GST: Most goods and services including electronics, textiles, soap, toothpaste
• 28% GST: Luxury items like cars, motorcycles, air conditioners, cigarettes

GST Components Explained

CGST (Central Goods and Services Tax)

CGST is collected by the Central Government on intra-state sales. It is half of the total GST rate. For example, if GST is 18%, CGST is 9%.

SGST (State Goods and Services Tax)

SGST is collected by the State Government on intra-state sales. Like CGST, it is also half of the total GST rate.

IGST (Integrated Goods and Services Tax)

IGST is applicable on inter-state sales and imports. It equals the full GST rate and is collected by the Central Government, which then distributes it to the respective states.

When to Use Exclusive vs Inclusive GST

Exclusive GST (Add GST)

Use this when you have a base price and need to add GST on top of it. This is common when:

• Setting product prices for B2B sales
• Creating invoices where GST is shown separately
• Calculating total cost including tax from a net price

Inclusive GST (Remove GST)

Use this when you have a final price that includes GST and need to extract the tax amount. This is useful for:

• Finding the base price from an MRP
• Calculating taxable value for GST returns
• Understanding how much tax is included in a total amount

GST Calculation Formulas

To Add GST (Exclusive)

• GST Amount = (Base Amount × GST Rate) ÷ 100
• Total Amount = Base Amount + GST Amount

To Remove GST (Inclusive)

• Base Amount = (Total Amount × 100) ÷ (100 + GST Rate)
• GST Amount = Total Amount - Base Amount

GST for E-commerce Sellers

E-commerce sellers must understand GST implications:

• GST Registration: Mandatory if annual turnover exceeds ₹20 lakhs (₹10 lakhs for special category states)
• Input Tax Credit: You can claim credit for GST paid on purchases
• Reverse Charge: Some marketplace platforms collect and deposit GST on your behalf
• E-invoice: Mandatory for businesses with turnover above ₹10 crores

Common GST Scenarios

Example 1: Adding GST to Product Price

If your product costs ₹1,000 and GST is 18%:

• CGST: ₹90 (9%)
• SGST: ₹90 (9%)
• Total GST: ₹180
• Final Price: ₹1,180

Example 2: Extracting GST from MRP

If MRP is ₹1,180 (inclusive of 18% GST):

• Base Price: ₹1,000
• CGST: ₹90
• SGST: ₹90
• Total GST: ₹180

Tips for GST Compliance

2. File Returns on Time: Monthly/quarterly GST returns must be filed by due dates
3. Display GST Correctly: Show GST number and breakdown on all invoices
4. Claim Input Tax Credit: Ensure you claim ITC for eligible purchases
5. Use Technology: Leverage tools like this calculator for accurate calculations

Frequently Asked Questions

What is the difference between CGST and SGST?

CGST goes to the Central Government and SGST goes to the State Government. Both are equal (each is 50% of total GST) and apply only to intra-state transactions.

When is IGST applicable instead of CGST + SGST?

IGST applies when goods or services are sold from one state to another (inter-state sales). In such cases, only IGST is charged, not CGST and SGST.

Can I claim input tax credit on all GST paid?

You can claim input tax credit on GST paid for business purposes. However, ITC is not available for certain items like motor vehicles (unless used for specific business purposes), food and beverages, and personal expenses.

Do I need to register for GST?

GST registration is mandatory if your annual turnover exceeds ₹20 lakhs (₹10 lakhs for special category states). E-commerce sellers must register regardless of turnover.
