GST invoice format for a doctor's clinic

A doctor's consultation is a health care service that is exempt from GST, so a clinic usually issues a bill of supply, not a tax invoice. The bill should show the doctor's medical council registration number, the patient's name, the date of visit and SAC 999312, with no GST charged on the fee. If the clinic also sells medicines over the counter, those lines are taxable goods at 5% and need a drug licence. Mixing both on one bill without separating them is the usual mistake.

Extra fields a doctor's clinic invoice needs

Medical council registration number
The exemption covers services by an authorised medical practitioner, meaning a doctor registered with a recognised medical council. Printing the registration number shows on the face of the bill why no GST was charged and reassures insurers processing reimbursement claims.
Patient name and age
Reimbursement and insurance claims are tied to a named patient, and the same family often visits together. Name and age on each bill stop confusion when a patient asks for duplicate receipts months later for tax or claim purposes.
Visit type (new, follow-up, procedure)
Clinics often charge less for a follow-up within a set number of days and more for a minor procedure. Labelling the visit type explains the fee difference to the patient and keeps your daily collection report readable.
Bill of supply declaration
Where the bill carries only exempt services, a line such as 'Bill of supply — health care services exempt under GST' tells the reader no tax is due. This avoids patients or employers questioning why there is no GST column.
Mode of payment and receipt number
Clinics take cash, UPI and cards across the day. Recording the mode against each bill makes the end-of-day cash count simple and gives the patient a clear receipt for income tax or employer reimbursement claims.
Procedure or injection details
When the doctor gives an injection, dressing or nebulisation during the visit, naming it on the bill shows it as part of the treatment, which keeps it within the exempt health care service rather than a separate sale of goods.

GST rules that matter for a doctor's clinic

Consultation is exempt health care

Notification 12/2017-Central Tax (Rate) exempts health care services provided by a clinical establishment, an authorised medical practitioner or paramedics. Health care means diagnosis, treatment or care for illness, injury, deformity, abnormality or pregnancy in any recognised system of medicine. A doctor's consultation, examination and treatment in the clinic falls within this, so the fee is billed with no GST. The exemption does not cover hair transplant or cosmetic and plastic surgery done for looks, unless it restores anatomy or function after a congenital defect, injury or trauma. Those services are taxable and need a tax invoice.

Do you need GST registration at all?

A person supplying only exempt services does not need GST registration, however large the turnover, because section 23 of the CGST Act excludes them. A doctor whose income is only consultation fees can stay unregistered. Registration becomes relevant once the clinic also sells taxable goods such as medicines or devices over the counter, or earns taxable income like cosmetic procedures, and the aggregate turnover, which includes exempt fees, crosses the threshold. Count exempt receipts in aggregate turnover when checking the ₹20 lakh limit for services or ₹40 lakh for goods-only businesses.

Medicines given during treatment versus sold separately

Medicines, injections and consumables used by the doctor while treating the patient during the visit form part of a composite health care service, so they ride on the exemption. Medicines that the patient buys to take home from the clinic counter are a separate sale of goods taxed at 5% under HSN 3004 since 22 September 2025. Keep them as separate lines, ideally on a separate tax invoice, and hold a valid drug licence for the counter.

Bill of supply and Rule 46 together

A registered clinic that supplies both exempt and taxable items can issue one invoice-cum-bill of supply under Rule 46A, showing exempt lines and taxable lines separately. If you are unregistered, you simply issue a receipt or bill without any GSTIN or tax columns. Never print a GSTIN on a bill if you are not registered, and never show 'GST 0%' as though tax were charged at a nil rate.

Renting your clinic premises can trigger tax for you

If a registered clinic rents its premises from an unregistered landlord, the reverse charge on renting of commercial property may make the clinic pay GST on the rent itself. Unregistered clinics are not affected. Exempt clinics cannot claim input tax credit on that tax, so it is a real cost. Check the landlord's registration status before signing or renewing a lease.

Common billing mistakes

  • Charging 18% GST on consultation fees because the billing software defaults every service to the standard rate.
  • Printing a GSTIN and tax columns on the bill when the doctor is not registered, which looks like tax was collected.
  • Lumping take-home medicines into the consultation fee to avoid tax, when over-the-counter sales are taxable at 5%.
  • Leaving out the doctor's registration number, so insurers question whether the exemption and the claim apply.

Doctor's clinic GST invoice: FAQ

Is GST charged on doctor consultation fees?

No. Consultation by a registered medical practitioner is a health care service exempt from GST. The clinic issues a bill of supply or receipt without tax. Cosmetic procedures done purely for appearance are an exception and are taxable.

Does a doctor need a GST number for the clinic?

Not if the clinic earns only exempt consultation and treatment fees. Registration is needed once taxable supplies, such as over-the-counter medicine sales, take aggregate turnover past the threshold, which counts exempt fees too.

What SAC code goes on a clinic bill?

Use SAC 999312 for medical and dental services. Inpatient care uses 999311 and nursing or physiotherapy uses 999314. Showing the code on the bill makes your records consistent even when no tax is charged.

Can a clinic sell medicines on the same bill as the consultation?

A registered clinic can issue a combined invoice-cum-bill of supply listing the exempt consultation and the taxable medicines separately with their own rates. Medicines to take home are taxed at 5% and need a drug licence.
