What GST rates apply in 2026?+
After GST 2.0 the slabs are 0%, 5%, 18% and 40%. The 12% and 28% slabs were abolished from 22 September 2025, but remain selectable here for invoices dated in earlier periods.
What is the difference between inclusive and exclusive GST?+
Exclusive means the amount you enter is the taxable value and GST is added on top. Inclusive means GST is already inside the figure, so the tool works backwards to split out the base and the tax.
When is it CGST plus SGST rather than IGST?+
Intra-state supplies — where the supplier and the place of supply are in the same state — split equally into CGST and SGST. Inter-state supplies carry IGST at the full rate.
Does this replace a tax invoice?+
No. This computes the split only. A valid tax invoice must carry every particular Rule 46 requires; our free invoice generator produces one.
Is anything I enter stored?+
No. Everything runs in your browser and nothing is submitted unless you choose to send us an enquiry.
