Looking for expert help with Income tax and GST for dentists and dental clinic owners India? The team at Tax Garden, based in Kondapur, Hyderabad, helps Indian SMEs stay compliant. End-to-end filings, notices, and deadline tracking, all in one place.
Key Takeaways
- Dental treatment is exempt from GST under S. No. 74 of Notification 12/2017-Central Tax (Rate). Purely cosmetic work may not be, and taxable heading 9993 services are 18%.
- A clinic doing only exempt treatment doesn't need GST registration. Sell one taxable item and your exempt treatment receipts count towards the Rs 20 lakh limit.
- You can't claim back the 18% GST on a dental chair or the 5% on instruments, because your output is exempt.
- Under Section 44ADA, 50% of receipts is taxed as profit. The limit is Rs 75 lakh only if cash is within 5% of receipts; otherwise it's Rs 50 lakh.
- Missed the 31 August 2026 ITR date for AY 2026-27? A belated return can still be filed by 31 December 2026, with a late fee of up to Rs 5,000.
Is GST applicable on dental treatment in India? No. Dental treatment by a registered dentist or a clinic is a health care service exempt under S. No. 74 of Notification 12/2017-Central Tax (Rate). The exemption covers diagnosis, treatment or care for illness, injury, deformity or abnormality. It does not cover cosmetic or plastic surgery done only for appearance, and products you sell over the counter are taxable.
A dentist's tax picture has two odd features. You don't charge GST on treatment, yet you pay GST on the chair, the instruments and the lab work, with no way to claim it back. And patients still pay a lot in cash, which quietly decides whether the Rs 75 lakh presumptive limit is open to you. This guide covers both, plus TDS on consultant fees and your AY 2026-27 dates. If you also run a pharmacy counter, read our guide for medical shop owners too. Physiotherapists face the same issues, covered in our physiotherapy clinic guide.
Is dental treatment exempt from GST?
Yes, for treatment. S. No. 74 of Notification 12/2017-Central Tax (Rate) exempts "health care services by a clinical establishment, an authorised medical practitioner or para-medics". Three definitions in the same notification decide whether you fit:
- Authorised medical practitioner (clause 2(k)): a practitioner registered with a council of a recognised system of medicines established or recognised by law in India.
- Clinical establishment (clause 2(s)): a hospital, nursing home, clinic or other institution offering diagnosis or treatment for illness, injury, deformity or abnormality.
- Health care services (clause 2(zg)): diagnosis, treatment or care for illness, injury, deformity, abnormality or pregnancy. It excludes hair transplant and cosmetic or plastic surgery, unless done to restore or reconstruct anatomy or function affected by congenital defects, developmental abnormalities, injury or trauma.
Fillings, root canals, extractions, scaling, gum treatment, dentures and braces for a bite problem are treatment of a dental condition. They're exempt whether you bill the patient directly or a hospital pays you as a visiting consultant. CBIC Circular 32/06/2018-GST (12 February 2018) says services of consultants hired by hospitals, whether employees or not, are exempt health care services.
Where does the dental GST exemption stop?
It stops at two points: work done only for looks, and goods you sell.
Cosmetic work. Teeth whitening, veneers chosen only for appearance and "smile makeovers" aren't treatment of an illness or injury. The exclusion in clause 2(zg) names cosmetic and plastic surgery, and the definition itself only covers treatment of a condition. So purely aesthetic work risks being taxable. Taxable human health services under heading 9993 are 18% GST (S. No. 31, Notification 11/2017-Central Tax (Rate)). The exception helps here: rebuilding a front tooth broken in an accident restores function lost to injury, so it stays exempt. Write the clinical reason in the case sheet.
Counter sales. Toothpaste, toothbrushes and floss sold to patients are supplies of goods, not treatment.

Does a dental clinic need GST registration?
Not if all you supply is exempt treatment. Section 23(1)(a) of the CGST Act says a person engaged exclusively in supplying exempt goods or services isn't liable to register.
"Exclusively" is the word that catches dentists. One taxable line, and the Rs 20 lakh threshold in Section 22 is tested on your aggregate turnover. Section 2(6) counts exempt supplies in aggregate turnover. So your treatment fees count.
Example: your clinic bills Rs 38,00,000 of treatment in a year and sells Rs 1,20,000 of toothpaste, brushes and mouthwash. Aggregate turnover is Rs 39,20,000, well above Rs 20 lakh. You must register and charge 5% on the paste and brushes and 18% on the mouthwash. Treatment stays exempt. If the counter earns you little, stopping it may be simpler than registering for it.
Once registered, Section 17(2) limits your input tax credit to the share of purchases used for taxable supplies. Say you buy a dental chair for Rs 4,00,000 plus 18% GST of Rs 72,000. Because the chair is used for exempt treatment, that Rs 72,000 can't be claimed. The chair goes into your books at Rs 4,72,000.

How is a dentist's income taxed under Section 44ADA?
Dentistry is a medical profession under Section 44AA(1), so Section 44ADA is open to you for FY 2025-26 (AY 2026-27). From tax year 2026-27, the same rules sit in Section 58(2), Table Sl. No. 3 of the Income-tax Act 2025.
Step-by-Step Guide
Can Your Clinic Use Section 44ADA?
Check who you are
Resident individual or partnership firm (not an LLP), carrying on the medical profession.
Work out your cash share
Add up treatment fees received in cash. A cheque that isn't account payee counts as cash. UPI, card and account payee cheques don't.
Cash 5% or less? Limit is Rs 75 lakh
If gross receipts are within Rs 75 lakh, 50% of receipts is your deemed profit. No tax audit while you declare under 44ADA(1).
Cash above 5%? Limit is Rs 50 lakh
Receipts above Rs 50 lakh rule out 44ADA. You keep full books, and receipts over Rs 50 lakh bring a tax audit under Section 44AB(b).
Declaring less than 50%?
If income is above the basic exemption limit, keep books and get an audit (Section 44ADA(4)).
Source: Sections 44AA(1), 44ADA and 44AB, Income-tax Act 1961 (FY 2025-26); Sections 58(2) Sl. No. 3, 62 and 63, Income-tax Act 2025 (from tax year 2026-27)
Example 1 (small clinic, new regime): gross receipts for FY 2025-26 are Rs 48,00,000, with Rs 5,76,000 (12%) in cash. Receipts are under Rs 50 lakh, so 44ADA applies even though cash is above 5%.
- Deemed profit: 50% of Rs 48,00,000 is Rs 24,00,000.
- Tax: Rs 20,000 (Rs 4-8 lakh at 5%) + Rs 40,000 (Rs 8-12 lakh at 10%) + Rs 60,000 (Rs 12-16 lakh at 15%) + Rs 80,000 (Rs 16-20 lakh at 20%) + Rs 1,00,000 (Rs 20-24 lakh at 25%) = Rs 3,00,000.
- Health and education cess at 4% is Rs 12,000. Total Rs 3,12,000. The Section 87A rebate doesn't apply above Rs 12 lakh.
Example 2 (busier clinic, same Rs 62,00,000 of receipts, two cash patterns):
- Cash Rs 2,50,000 (about 4%): the limit is Rs 75 lakh. Deemed profit is Rs 31,00,000. Tax is Rs 3,00,000 on the first Rs 24 lakh plus 30% of Rs 7,00,000 (Rs 2,10,000), so Rs 5,10,000, plus cess of Rs 20,400. Total Rs 5,30,400. No tax audit, because of the first proviso to Section 44AB.
- Cash Rs 6,20,000 (10%): the limit drops to Rs 50 lakh, and Rs 62 lakh is above it. 44ADA is gone. You keep full books, pay tax on actual profit, get a tax audit under Section 44AB(b), and file ITR-3.
Same clinic, same patients. The only difference is how they paid. Moving implant and orthodontic instalments to UPI or card is the most useful thing a busy clinic can do here.
One more cash rule: you can't receive Rs 2 lakh or more in cash from one patient in a day, for a single transaction, or for transactions relating to one event or occasion (Section 269ST; Section 186 of the 2025 Act). An implant case paid in cash instalments can cross that. The penalty under Section 271DA is equal to the amount received. Our Section 44ADA guide and the doctors' income tax guide cover the scheme in more depth.
Do you deduct or suffer TDS as a dentist?
Both can happen.
As a visiting consultant. A hospital or corporate dental chain run as a firm, LLP or company deducts 10% TDS on your fees once payments cross Rs 50,000 in the year. That's Section 194J for FY 2025-26, and Section 393(1), Table Sl. No. 6(iii) of the Income-tax Act 2025 for payments from 1 April 2026. Match the credit in Form 26AS or AIS before you file.
As a payer. If your own clinic is a proprietorship and your professional receipts exceeded Rs 50 lakh in the previous year, you deduct 10% on fees above Rs 50,000 a year paid to consultant endodontists, orthodontists or oral surgeons (second proviso to Section 194J; the "specified person" definition in Section 402(37) of the 2025 Act). A firm or company clinic deducts regardless of receipts. Our Section 194J guide has the details, and our TDS filing service can run the quarterly returns.

Common mistakes dentists make
- Running a product counter without checking registration. A few lakh of toothpaste and mouthwash sales can pull your whole treatment turnover into the Rs 20 lakh test.
- Calling cosmetic work "treatment" with nothing on file. If a procedure restores function after injury or a developmental problem, record that in the case sheet. If it's purely aesthetic, decide on the GST position before you bill it, not after a notice.
- Ignoring the cash share. At Rs 50-75 lakh of receipts, cash above 5% removes 44ADA and adds a tax audit.
- Taking Rs 2 lakh or more in cash for one implant or ortho case. Staged cash payments for one treatment can still breach Section 269ST.
- Not reconciling TDS from hospitals. Credit missing from Form 26AS or AIS usually means a wrong PAN or an unfiled TDS return at the hospital's end. Chase it before you file.
