When the amount excludes GST, CGST and SGST are each half the rate applied to the amount, rounded to the paisa; between states, IGST is the full rate. The total is the amount plus the tax.
When the amount includes GST, the taxable value is the amount × 100 ÷ (100 + rate), rounded to the paisa, and GST is the difference. CGST is half of that, rounded, and SGST is the rest, so the parts always add up exactly.
Questions
When do I use CGST and SGST, and when IGST?
CGST and SGST (or UTGST in some union territories) apply when the supplier and the place of supply are in the same state. IGST applies when they are in different states.
How do I remove GST from a price?
Choose "Amount includes GST". The taxable value is the price × 100 ÷ (100 + GST rate), and the GST is the price minus that value.
Which GST rate should I use?
The rate depends on the exact goods or service and its HSN or SAC code. Rates were revised in 2025, so check the current rate for your item on the GST portal or with your tax professional.
