GST invoice format for a dental clinic

Dental treatment such as fillings, root canals, extractions and braces to correct a defect is exempt health care, so a dental clinic bills it on a bill of supply under SAC 999312. A dental bill also needs tooth numbers, a treatment plan with sittings, staged payments and the dentist's Dental Council registration. Purely cosmetic work such as teeth whitening done only for looks falls outside the exemption and needs a tax invoice, so the clinic must separate it from treatment.

Extra fields a dental clinic invoice needs

Tooth number (FDI notation): Dental work is done tooth by tooth. Writing the FDI tooth number, such as 36 for the lower left first molar, shows exactly which tooth was treated and avoids disputes when the patient returns for further work.
Treatment plan and sitting number: Root canals and orthodontics run across several visits. Showing 'sitting 2 of 4' and the total plan cost helps patients budget and makes interim bills easy to reconcile against the final total.
Dental Council registration number: The exemption depends on the service being provided by an authorised practitioner. The dentist's State Dental Council registration on every bill supports both the exemption and any insurance claim.
Advance and balance due: Patients often pay a deposit before braces or implants. Recording the advance, payments so far and balance due on each bill gives a running account and avoids double-charging across sittings.
Lab work description: Crowns, bridges and dentures are made by an outside dental lab. Naming the restoration type and material on the bill explains the cost and helps if a crown needs replacement under warranty.
Cosmetic or treatment flag: Mark each line as treatment or cosmetic so the billing system applies the exemption only where it belongs and tax invoices are generated for elective cosmetic work.

GST rules that matter for a dental clinic

Treatment exempt, cosmetic work taxable

The exemption for health care covers diagnosis and treatment of illness, injury, deformity or abnormality. Most dentistry treats disease or corrects a defect: fillings, root canal treatment, extractions, gum treatment, dentures and orthodontics to fix malocclusion. The exemption expressly excludes cosmetic or plastic surgery except where it restores function or anatomy after a congenital defect, developmental abnormality, injury or trauma. Teeth whitening, veneers chosen only for appearance and smile design done purely for looks are therefore taxable. Record the clinical reason so a later reviewer can see why each line was treated as exempt.

Registration when you add taxable services

A dental clinic offering only treatment does not need GST registration. Once it offers cosmetic procedures or sells products, and its aggregate turnover crosses the threshold, it must register. Aggregate turnover includes the exempt treatment income, so even a modest amount of whitening work can trigger registration at a busy clinic. After registering, use an invoice-cum-bill of supply for mixed visits.

Dental lab bills and implants

Outside dental labs make crowns and bridges for the clinic. Since the clinic's treatment is exempt, any GST charged by the lab cannot be claimed as credit and becomes part of the clinic's cost. Implants and other materials fitted during treatment are part of the composite health care service billed to the patient without tax. Do not list the implant as a separate taxable sale on the patient's bill.

Products sold at the clinic

Clinics often sell toothpaste, brushes, mouthwash and floss. Toothpaste, dental floss and toothbrushes were cut to 5% from 22 September 2025. These are retail goods outside the exemption, so if the clinic is registered they need a tax invoice line with HSN 3306 or 9603 and the 5% rate. Unregistered clinics below the threshold sell them without charging tax.

Dental equipment purchases

Dental chairs, instruments and X-ray units under headings 9018 and 9022 moved to 5% in the 2025 rationalisation. A clinic cannot claim this tax as credit against exempt output, so the lower rate cuts the cost of setting up. Keep the invoices anyway, since depreciation for income tax is calculated on the tax-inclusive cost when credit is not claimed.

Common billing mistakes

Treating teeth whitening and purely cosmetic veneers as exempt treatment.
Showing implants or crowns as separate taxable goods on a treatment bill instead of part of the exempt service.
Not recording tooth numbers, which leads to disputes when the same patient returns for another tooth.
Ignoring exempt treatment income when checking whether cosmetic billing has pushed turnover past the registration limit.

Dental clinic GST invoice: FAQ

Is GST applicable on dental treatment?

No for treatment of disease or defects, such as fillings, root canals, extractions and corrective braces. Yes for purely cosmetic work, such as teeth whitening done only for appearance, which needs a tax invoice.

Is GST charged on dental implants?

An implant placed as part of treatment to replace a lost tooth is part of the exempt health care service, so no GST appears on the patient's bill. The clinic pays GST on the implant it buys and cannot claim it back.

What should a dental clinic bill include?

The dentist's registration number, patient name, tooth numbers, procedure, sitting number, amount paid and balance due, and SAC 999312. Cosmetic lines and retail products go on a tax invoice with their GST rate.

Do orthodontic braces attract GST?

Braces fitted to correct misaligned teeth or bite problems treat an abnormality and are exempt. If the clinic markets a purely cosmetic aligner service with no clinical need recorded, the exemption becomes hard to defend.
