GST calculator for clinics
Work out the GST on any amount and see the exact CGST + SGST or IGST split. Add GST to a pre-tax figure, or extract the tax already baked into a price.
Same-state supply splits into CGST + SGST; inter-state is a single IGST at the full rate. Figures are indicative — confirm the correct rate and HSN/SAC for each line with your accountant.
How the GST split works
Every taxable line on a GST invoice carries a rate. When the patient and the place of supply are in the same state, that tax is shared between the centre and the state: half as CGST and half as SGST. When the supply crosses a state border, a single IGST at the full rate replaces both. The amount of tax is identical — only the heads differ — but a compliant invoice has to show the correct split.
The other common question is whether a price includes GST. A counter MRP usually does; a quoted professional fee usually does not. Use Add GST when your figure is pre-tax, and Extract GST when the tax is already inside the number.
Knowing the split is one thing; picking the right rate is another. Most core clinical services are exempt, while goods and some services are taxable. Our GST billing guide and the HSN/SAC primer cover which is which.
Frequently asked questions
- How is GST calculated on a clinic invoice?
- Take the taxable value of a line and apply its GST rate. For a same-state patient the tax splits into CGST and SGST at half the rate each; for an inter-state supply it is a single IGST at the full rate. The taxable value plus the tax is the invoice total.
- What is the difference between CGST, SGST, and IGST?
- CGST and SGST apply together on a supply within the same state, each at half the GST rate. IGST applies on an inter-state supply, at the full rate, instead of CGST and SGST. The total tax is the same either way; only the split differs.
- How do I work out the GST from a price that already includes it?
- Switch the calculator to Extract GST. It divides the inclusive amount by one plus the rate to find the taxable value, and the difference is the GST. For example, ₹1,180 at 18% inclusive is ₹1,000 taxable plus ₹180 GST.
- Is GST charged on a doctor's consultation?
- Most core healthcare services by a clinical establishment are exempt, so a consultation is typically nil-rated. But the exemption is not blanket — taxable goods and certain services still attract GST. See our GST guides for which lines are exempt and which are not.
- Which GST rate applies to medicines or cosmetic procedures?
- It depends on the item, and rates change. Many medicines sit around 5%, and purely cosmetic procedures became taxable rather than exempt. Confirm the correct rate and HSN/SAC code for each line with your accountant; this tool computes the split once you choose the rate.
