Does a clinic need GST registration in India?

It depends on your taxable turnover, not your total turnover. That one word is where most clinics get the answer wrong.

A clinic that only consults and treats can stay outside GST registration completely, even if it bills more than ₹20 lakh a year. Add a pharmacy or some aesthetic work, and the rules change. Here's how the line is drawn.

The thresholds

A supplier of services has to register once aggregate turnover crosses ₹20 lakh (₹10 lakh in special category states). For a supplier of goods, the limit is ₹40 lakh (₹20 lakh in some states). "Aggregate turnover" is the all-India figure on one PAN, and it counts taxable supplies, exempt supplies, exports, and inter-state supplies together.

Hold on to that last point. It matters more than it looks.

The exemption doctors don't expect

Section 23 of the CGST Act says a person supplying only wholly exempt or non-taxable goods or services is not liable to register. Not "below the threshold." Not at all.

So a doctor whose entire income is consultation and treatment can bill ₹30 lakh, ₹50 lakh, more, and still need no GSTIN, because every rupee of it is exempt. The threshold never bites, because the section that exempts you from registration doesn't care about the number.

The trap: the day you add a taxable supply

Here's where it turns. Section 23 protects you only while you are exclusively exempt. The moment you make even one taxable supply, you're no longer in that box, and the threshold test wakes up.

And now that earlier point bites: aggregate turnover includes your exempt consultation income. So picture a clinic doing ₹30 lakh of consultations and ₹4 lakh of counter pharmacy. It isn't ₹4 lakh that's tested against ₹20 lakh. It's the combined ₹34 lakh. The pharmacy is small, but it drags the whole turnover into the calculation, and the clinic is over the line.

That's the part that surprises people. A modest taxable side activity can pull a large exempt practice into registration.

Registering doesn't tax your consultations, though. Even once you have a GSTIN, the exempt care stays exempt and goes out on a bill of supply. You only charge GST on the taxable lines, the pharmacy or the aesthetic work. So "over the line" means you collect tax on the taxable part, not on everything.

When you must register no matter the size

Section 24 lists cases where registration is required regardless of turnover. The one most relevant to clinics is making a taxable inter-state supply. If any of these apply, the threshold doesn't help you. This is worth checking with a CA rather than assuming.

Common questions

A solo doctor bills ₹35 lakh, only consultations. GSTIN needed?

No. That's exclusively exempt income, so Section 23 keeps the clinic out of registration even well above ₹20 lakh.

Same doctor opens a small pharmacy counter. Now?

Now the clinic isn't exclusively exempt. Aggregate turnover counts the consultations plus the pharmacy, that total is over ₹20 lakh, so registration is due.

Does exempt consultation income really count toward the threshold?

Yes, once you're not exclusively exempt. People assume only the taxable part is counted. It isn't.

How Avinya Plus helps you see the line coming

In Avinya Plus, each catalogue item is tagged exempt or taxable, so your reports separate the two instead of lumping them. When you're weighing whether a pharmacy counter or an aesthetic service tips you into registration, you can see the taxable side as its own number rather than guessing. It also handles the exempt-vs-taxable mix on the bill itself once you are registered.

This is general information, not tax advice. Thresholds, special-category state lists, and Section 24 cases change. Confirm your clinic's position with a chartered accountant before deciding either way.
