Questions
How do I remove GST from a price?
Choose "Remove GST". The tool divides the amount by (100 + rate) / 100 to find the price before tax.
When is IGST used?
For supplies from one state to another, and for imports.
Why are CGST and SGST different by a paisa?
When the tax has an odd number of paise, one paisa goes to SGST so the total stays exact.
Which rates can I use?
Any rate. Common rates are shown as quick buttons.
Is this tax advice?
