This guide is general information, not legal or tax advice. GST rules and notifications change, and your own facts matter. Read the current text on the official CBIC pages linked below and confirm your format with a chartered accountant.
What every dental bill should include
Whether or not GST applies to you, a bill has two jobs. It tells the patient what was done and what it cost, and it gives you a record you can find again. These parts do both:
- Clinic details: name, address and phone number.
- The treating dentist and registration number. The Revised Dentists (Code of Ethics) Regulations, 2014 say, in clause 3.4.1, that every dental practitioner shall display the registration number given by the State Dental Council in the clinic and in all prescriptions, certificates and money receipts given to patients. The dental regulator changed in 2026, so confirm the current rule, but printing the number is a safe habit.
- Patient details: name, and a phone number or patient ID if you use one.
- A bill number and the date. Number bills in sequence and never reuse a number.
- Each treatment on its own line, with the tooth or area where it helps, the quantity and the fee. Avoid one lump sum.
- Discount, if any, shown as its own line so the original fee is still visible.
- GST, only on lines where it applies, and only if you are registered.
- Total, amount received, payment mode and balance due. Patients often pay in parts, so the balance matters as much as the total.
- A signature or clinic stamp on a paper bill.
Keep it to one page. If a treatment runs over several sittings, bill each stage when it is done, and let the balance carry forward in the patient’s ledger.
A sample dental bill format
Under your letterhead (clinic name, address, phone, dentist and registration number), the bill number, the date and the patient’s name, the body of a simple bill looks like this:
The ₹ figures below only show the layout. They are not market rates or a recommendation. Use the fees from your own price list.
| Treatment | Tooth / area | Qty | Fee | Amount |

| Consultation and IOPA X-ray | 46 | 1 | ₹500 | ₹500 |
| Root canal treatment (molar) | 46 | 1 | ₹6,000 | ₹6,000 |

If your clinic is not registered for GST
Most dental treatment is an exempt health care service; our guide to GST on dental services explains the exemption and its limits. Under section 23 of the CGST Act, a person engaged exclusively in supplying goods or services that are wholly exempt from tax is not liable to register. Many dental clinics are in this position.
The GST invoice rules described in the next section are written for registered persons. If you are not registered, the GST law does not give you a bill format to follow. Three points still apply:
- Do not print a GSTIN, and do not charge or show GST on the bill. Section 32 of the CGST Act says a person who is not registered shall not collect any amount by way of tax.
- Do not call the document a “tax invoice”. “Bill”, “receipt” or “cash memo” is accurate.
- Keep a copy of every bill. Your CA needs them for your income tax records, and a patient may ask for a duplicate for an insurance or employer claim.
If your clinic is registered for GST
A clinic may be registered because it also does taxable cosmetic work or sells goods. Once you are registered, the document you issue depends on what is being billed:
| What you are billing | Document | Where it comes from |
|---|---|---|
| Exempt treatment only | Bill of supply | Section 31(3)(c) says a registered person supplying exempted goods or services shall issue a bill of supply instead of a tax invoice. Rule 49 lists what it must contain. |
| Taxable items only | Tax invoice | Rule 46 lists the particulars, including the taxable value, the rate of tax and the amount of tax. |
| Exempt and taxable items for the same patient | One invoice-cum-bill of supply | Rule 46A allows a single document when the recipient is unregistered, as patients are. It must carry the particulars of both rules. |
Rule 49 says a bill of supply contains these details:
- Name, address and GSTIN of the supplier, which is your clinic.
- A consecutive serial number of not more than sixteen characters, in one or more series, unique for a financial year. It may contain letters, numerals, the hyphen and the slash.
- The date of issue.
- Name, address and GSTIN of the recipient, if the recipient is registered. An ordinary patient is not.
- The HSN code for the goods or services. Service codes are often called SAC. Ask your CA which code to print and how many digits you need.
- A description of the goods or services.
- The value of the supply, taking into account any discount.
- The signature or digital signature of the supplier or an authorised representative. The rule says this is not required on an electronic bill of supply issued in accordance with the Information Technology Act, 2000.
A tax invoice under rule 46 has more fields. The ones a clinic will notice are the taxable value, the rate and amount of each tax, and the recipient’s name and address when the taxable value is ₹50,000 or more. E-invoicing and QR code requirements apply only above turnover limits set by notification; your CA will tell you if they reach you.
Small bills under ₹200
This also applies only to registered clinics. Section 31(3) says a registered person may not issue a tax invoice, or a bill of supply, when the value supplied is less than two hundred rupees, subject to conditions in the rules. Rule 46 sets the conditions: the recipient is not a registered person and does not require the document. In that case you issue one consolidated document at the close of each day for all such supplies. Rule 49 applies the same provisos to bills of supply.
In practice few dental charges are below ₹200, and most patients want a bill. Giving every patient a bill is simpler than keeping a separate daily list.
Bills, receipts and advance payments
A bill records treatment done and what it cost. A receipt records money received. When the patient pays in full on the day, one document can do both jobs if it shows the amount received and the payment mode. When they pay in parts, give a receipt for each payment and keep the bill as the record of what was charged.
Advances need care. If a patient pays before treatment, for example a deposit for a crown or for braces, give a receipt that says it is an advance and what it is for. For registered persons, section 31(3)(d) requires a receipt voucher when an advance payment is received, and rule 50 lists its particulars. How this applies to an advance for exempt treatment is a question for your CA.
Before treatment starts, the right document is an estimate, not a bill. See our guide to the dental treatment estimate format.
Common mistakes on dental bills
- One lump sum. “Dental treatment ₹12,000” invites a dispute. Itemise it.
- No bill number, or numbers that restart every month. A duplicate number makes two bills impossible to tell apart later.
- Charging GST without being registered, or printing a GSTIN that is not yours.
- A “tax invoice” heading on exempt treatment. A registered clinic uses a bill of supply for exempt items.
- No registration number for the treating dentist.
- Mixing the estimate with the bill. Bill only what has been done.
- Not showing the balance. If ₹3,500 is still due, print it, so the patient and the front desk agree on the figure at the next visit.
- Handwritten corrections. If a bill is wrong, cancel it and issue a new one with a new number.
In OPD Sathi, bills are made at checkout from your treatment price list, where each item has a default price and a GST rate. Every charge and payment goes into the patient’s khata, so part payments and dues stay clear, and a receipt for any payment can be sent as a PDF on WhatsApp or email. If you are GST-registered, ask your CA to confirm that the layout you use carries every detail the rules require for your clinic.
