Do physiotherapists need GST registration in India?

"Do I need a GSTIN?" is one of the most common questions a new physiotherapy clinic owner asks — and the honest answer is probably not, but it depends on what else you sell. Charging GST and being registered for GST are two different things, and the rules turn on what your clinic actually supplies. Here's the careful version.

Charging GST vs. registering for GST

These get conflated constantly, so separate them first:

• Charging GST is about whether a particular supply is taxable. Most physiotherapy treatment is exempt healthcare — we cover the why in detail in GST on physiotherapy services in India.
• Registering for GST is about whether you must obtain a GSTIN at all, based on the type and value of your supplies.

A clinic can be doing everything right on the first and still wonder about the second. So let's look at registration on its own terms.

The registration threshold

Under Section 22 of the CGST Act, a supplier of services generally becomes liable to register once aggregate turnover crosses ₹20 lakh in a financial year. In the special-category states (a defined list that includes several north-eastern and hill states), that threshold is ₹10 lakh.

Two things worth flagging:

• The widely-quoted ₹40 lakh higher limit applies to suppliers of goods only — it does not apply to a service business like a physiotherapy clinic. For services, plan around ₹20 lakh / ₹10 lakh.
• The exact list of special-category states has changed over the years. If your clinic is in the north-east or a hill state, confirm your state's current status with a CA rather than assuming.

Section 23: making only exempt supplies

Here is the part that matters most for a treatment-focused clinic. Section 23 of the CGST Act says a person engaged exclusively in supplying exempt goods or services is not liable to register — and this exemption is generally understood to apply regardless of turnover.

So a clinic that only provides exempt healthcare physiotherapy can, in principle, cross ₹20 lakh and still not be required to register, because everything it supplies is exempt. Section 23 is treated as overriding the Section 22 threshold for such persons.

That is a powerful but narrow door. It depends on everything you supply being exempt. The moment something taxable enters the mix, the analysis changes.

How aggregate turnover is computed (this trips people up)

When you do have to test against the ₹20 lakh threshold, "aggregate turnover" is not just your taxable sales. Under Section 2(6), it includes, on an all-India PAN basis:

• taxable supplies, plus
• exempt supplies, plus
• exports, plus
• inter-state supplies

In other words, your exempt physiotherapy revenue counts toward the ₹20 lakh number for the threshold calculation. That feels counter-intuitive — exempt income still gets totted up — and it's exactly why mixed clinics need to do the math carefully.

When a clinic also makes taxable supplies

Most clinics don't only treat patients. The common taxable add-ons:

• Selling goods — TENS units, braces, exercise bands, orthotics, supplements.
• Non-treatment services — general fitness or wellness memberships, corporate ergonomic workshops with no diagnosed condition.

Once you make any taxable supply, Section 23's "only exempt" shelter no longer covers you, and you're back under Section 22. The practical trigger looks like this:

*₹10 lakh in special-category states. The threshold tests total aggregate turnover (exempt + taxable), but once registered you still don't add GST to the exempt treatment — only to the taxable goods/services.

There are also separate rules (Section 24) that can force registration regardless of turnover — for example certain inter-state taxable supplies or liability under reverse charge. A typical single-location clinic rarely hits these, but if you supply across state lines or import services, raise it with your CA.

What about voluntary registration?

You can register voluntarily even when you're not required to. The trade-offs:

• Upside — you can claim input tax credit on taxable purchases, and a GSTIN can look more credible to corporate or insurer clients.
• Downside — registration brings ongoing return-filing obligations and compliance overhead, and for a clinic whose income is mostly exempt, the input-credit benefit is often limited (you can't claim credit attributable to exempt supplies).

For a small, treatment-only clinic, voluntary registration usually adds cost without much benefit. For a clinic with a real retail or wellness arm, it may be worth it — but that's a numbers conversation with your accountant, not a default.

The practical takeaway

• Treatment-only clinic → generally no registration needed, even past ₹20 lakh, thanks to Section 23.
• Selling equipment or running taxable wellness → test your total aggregate turnover (exempt + taxable) against ₹20 lakh / ₹10 lakh.
• Whatever you decide, keep clean, sequential, correctly-labelled bills — see what a physiotherapy bill should include — so your turnover and GST position are easy to prove.
