Frequently asked questions
Is GST charged on a doctor consultation?
No. Healthcare services by a clinical establishment are GST-exempt, so a consultation or clinical procedure is billed on a Bill of Supply with no GST. GST applies to taxable items such as retail pharmacy and certain diagnostics.
How do I split GST into CGST and SGST?
For a sale within the same state, GST is split equally into CGST and SGST (for example 18% becomes 9% CGST + 9% SGST). For a sale to another state, the whole amount is IGST.
How do I remove GST from a total?
To find the base value from a GST-inclusive amount, divide by (1 + rate/100). This calculator does it for you when you choose the GST inclusive option.
