What isGST – Goods and
Services Tax?
Goods and Services Tax (GST) is an indirect tax in India, implemented on July 1, 2017. It replaced multiple prior taxes like VAT, excise duty, and service tax. GST is destination-based and collected at each stage of production and distribution, ultimately borne by the end consumer. There are four types of GST — CGST, SGST, IGST, and UTGST — each applicable based on the nature and origin of the transaction.

GST CalculationFormula
The GST amount is calculated using the following standard formula:
For inclusive amounts (reverse calculation):
- Pre-GST Price: Total Amount × 100 ÷ (100 + Rate)
- GST Amount: Total Amount − Pre-GST Price
Example
GST Exclusive Calculation
- Item: Furniture worth ₹1,000
- GST Rate: 18%
GST Amount = ₹1,000 × 18 ÷ 100 = ₹180
Total Price = ₹1,000 + ₹180 = ₹1,180
GST Inclusive Calculation
- Total Price (inclusive): ₹1,180
- GST Rate: 18%
Pre-GST = ₹1,180 × 100 ÷ 118 = ₹1,000
GST Amount = ₹1,180 − ₹1,000 = ₹180

State Goods and Services Tax
Levied by state governments on intra-state supply. Collected simultaneously with CGST, the revenue goes directly to the respective state government.
Integrated Goods and Services Tax
Levied by the central government on inter-state supply and international transactions. IGST replaces both CGST and SGST for cross-border trade.
