Frequently asked questions

How do I remove GST from a total?

Select 'Remove GST', enter the GST-inclusive amount, and pick the rate. The tool works backward to show the original base price and the tax component.

What is the CGST/SGST split?

For intra-state supplies, GST is divided equally into CGST and SGST. So 18% GST is 9% CGST + 9% SGST. The tool shows this split automatically.

Which GST rate applies to my product?

GST rates depend on the specific goods or service. This tool calculates for whichever rate you select; check the official GST rate schedule for your item.
