Method
How this is worked out
Every figure the tool uses is listed here. Assumptions are fields in the tool, so you can change them to match your business.
- Adding GST: tax = taxable value × rate. Taking GST out: taxable value = amount ÷ (1 + rate).
- Within a state the tax is split equally into CGST and SGST. In a union territory without a legislature it is CGST and UTGST. Between states, or between a state and a UT, it is IGST.
- Each tax line is rounded to the paisa, and the invoice total is the sum of the lines. Taking GST out can leave a one-paisa difference from the amount you typed, which the tool shows.
Questions
Questions people ask
How do I take GST out of a price that already includes it?
Divide the price by 1 plus the rate. For ₹1,180 at 18%, ₹1,180 ÷ 1.18 = ₹1,000 taxable value, and ₹180 is the GST.
When is it CGST and SGST, and when is it IGST?
When the supplier and the place of supply are in the same state, the tax is split equally into CGST and SGST. When they are in different states, the whole tax is IGST.
When does UTGST apply?
Inside Chandigarh, Ladakh, Lakshadweep, Andaman and Nicobar Islands, and Dadra and Nagar Haveli and Daman and Diu, which have no legislature. Delhi, Puducherry and Jammu and Kashmir charge SGST.
