Frequently asked questions
How is GST split into CGST and SGST?
For a supply within the same state (intra-state), the GST rate is split equally into CGST and SGST. For a supply across states (inter-state), the full rate is charged as IGST. This tool applies that place-of-supply rule automatically.
What is a GST-inclusive price?
A GST-inclusive (or "tax-inclusive") price already contains the tax. The calculator back-calculates the taxable value as amount × 100 ÷ (100 + rate), then derives the tax from it.
Which GST rates does it support?
The common Indian GST slabs: 0%, 0.25%, 3%, 5%, 12%, 18% and 28%. Pick the slab that applies to your goods or service (use the HSN/SAC finder if unsure).
