GST calculator for clinics

Work out the GST on any amount and see the exact CGST + SGST or IGST split, whether your figure is pre-tax or already includes the tax. Switch to Itemised to build a multi-line bill, taxable and exempt lines together, and print the totals.

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. Answer "Does your amount include GST?" with No when your figure is pre-tax, and Yes 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?
Answer "Does your amount include GST?" with Yes. The calculator then 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.
Do the amounts I type get uploaded?
No. GST arithmetic runs in your browser; invoice amounts stay local. Print if you want a copy you keep yourself.

Intra-state supplies attract CGST + SGST and inter-state supplies attract IGST under the CGST/IGST Acts; this tool applies the slab you pick to the amount you enter. It does not decide the correct rate or HSN/SAC for a given service. GST rates and rules change; confirm the current notified rate and your registration position with a CA or the CBIC portal.

Stop calculating GST by hand.

Avinya Plus posts the correct CGST + SGST or IGST on every line automatically, with the right HSN/SAC, and prints a compliant A4 or 80mm thermal invoice. See it on your own services.
