How to use this calculator
- Enter the amount, the GST rate and whether the amount includes tax.
- Choose the rate and the type of supply to match your situation.
- Read the taxable value, the tax split and the total in the result.
Rates depend on the goods or service; confirm the rate against the current notification.
The result is an estimate for the figures you enter. It is not a filed return, a certificate or professional advice. Rates, thresholds and section numbers change with each Finance Act, and the Income-tax Act, 2025 applies from 1 April 2026 with new section and form numbers.
