Indicative only — not tax advice
This tool is a guide, not a filing. Figures change with every Finance Act and notification; verify the applicable rate and threshold with a professional before relying on them.
Amount
The price of the supply — enter it with or without commas, e.g. 1,00,000.
Does it include GST?
GST rate
Supply type
Intra-state supplies split the tax evenly into Central GST and State GST; inter-state supplies are taxed as a single Integrated GST. The slab you pick must match the HSN/SAC of your goods or service — use the HSN/SAC lookup if unsure.
