Most healthcare services delivered to patients in Ontario are exempt from HST, meaning the provider does not charge the 13% tax on them. This covers the services of doctors, dentists, nurses and many regulated health professionals, as well as most hospital and long-term care services. The trade-off is that, because these are exempt rather than zero-rated, the provider generally cannot recover the HST it pays on its own expenses through input tax credits. Some health-adjacent services, such as purely cosmetic procedures, certain medical-legal reports and many wellness or non-regulated services, are taxable. Knowing which side of the line each revenue stream falls on is what keeps a healthcare practice compliant and correctly costed.

Exempt, Zero-Rated and Taxable: The Distinction That Matters

Healthcare HST confuses even experienced bookkeepers because "no HST charged" can mean two very different things. The difference decides whether you can recover the HST on your expenses. Our healthcare accounting team draws this line for clinics every day, and it rests on three categories.

Exempt supplies. No HST is charged to the patient, and the provider generally cannot claim input tax credits on related expenses. Most core medical and dental care sits here.
Zero-rated supplies. HST applies at 0%, so still no tax to the customer, but the provider can claim input tax credits. Few healthcare services are zero-rated; certain medical devices and prescription drugs are the common examples.
Taxable supplies. HST at 13% is charged, and input tax credits are available. Cosmetic procedures, many medical-legal services and non-regulated wellness services often fall here.

The practical point is that "exempt" is not the best outcome for a business, it simply means no tax is collected and none is recoverable. "Zero-rated" is the favourable category because the customer pays nothing and the provider still recovers its HST. For a deeper treatment of the mechanics, see our guide to GST/HST exempt versus zero-rated.

1. What Is Exempt: Core Healthcare Services

The Excise Tax Act exempts most services that are part of recognized healthcare. In a typical Ontario practice that includes consultations, examinations, diagnoses and treatment provided by a physician to a patient, most dental services, nursing services, and the services of many regulated health professionals when rendered to a patient. Hospital services and most long-term residential care are also exempt. When the service is genuine healthcare delivered to the patient, the default is exempt, and no HST is charged.

Practical point: Exempt does not mean ignore HST. You still have to identify your taxable streams, decide whether you must register, and account for the HST you cannot recover as a real cost of the practice.

2. The Input Tax Credit Trap

This is the rule that surprises healthcare owners the most. Because exempt services do not charge HST, the practice generally cannot recover the HST it pays on rent, equipment, supplies and software through input tax credits. That HST becomes a permanent cost. A clinic that buys $50,000 of equipment pays $6,500 of HST it usually cannot get back, where a fully taxable business would recover all of it. Pricing, budgeting and equipment decisions in a healthcare practice all have to account for non-recoverable HST.

Where it goes wrong: Claiming input tax credits against exempt revenue. A bookkeeper who treats a medical clinic like an ordinary taxable business and claims ITCs on all its expenses creates an HST liability that the CRA will reassess. Exempt revenue and its expenses must be tracked separately.

3. What Is Taxable: The Streams That Catch Practices Out

Not everything a healthcare practice earns is exempt. Purely cosmetic procedures done for appearance rather than a medical purpose are generally taxable. Many medical-legal services, independent examinations and reports prepared for third parties such as insurers or lawyers are taxable. Sales of retail products, certain non-regulated wellness or aesthetic services, and rental of space or equipment to other practitioners can all be taxable. A practice with even one significant taxable stream may cross the registration threshold and have to charge and remit HST on that portion.

4. Mixed Practices and Apportionment

Many real clinics earn both exempt and taxable revenue, a family practice that also offers cosmetic injectables, or a dentist who sells products alongside exempt dental care. These mixed practices are the most complex. The taxable portion may require HST registration and collection, while the exempt portion does not, and input tax credits can only be claimed to the extent expenses relate to the taxable activities. Getting the apportionment right, and documenting it, is exactly the kind of work a healthcare-experienced CPA handles.

5. Registration: When a Health Practice Must Register

A practice providing only exempt services generally does not register for HST, because it makes no taxable supplies. Once taxable supplies exceed the small-supplier threshold over four calendar quarters, registration becomes mandatory for that taxable activity. The mistake we see is a clinic that has quietly grown a taxable stream, cosmetics, products or third-party reports, past the threshold without registering. GST/HST filing and registration for healthcare needs to track the taxable revenue, not the total revenue.

A Simple Worked Example

Consider a clinic with $500,000 of revenue, made up of $440,000 exempt medical services and $60,000 taxable cosmetic services, that spends $30,000 of HST-bearing expenses split evenly across both:

Item	Treatment
$440,000 medical services	Exempt, no HST charged
$60,000 cosmetic services	Taxable, HST charged and remitted
HST on expenses tied to medical work	Not recoverable
HST on expenses tied to cosmetic work	Recoverable as input tax credits

The clinic must register because its taxable supplies exceed the threshold, charge HST on the cosmetic work, and may claim input tax credits only on the expenses connected to that taxable stream, not on the expenses tied to exempt medical care. Treating the whole clinic as exempt, or the whole clinic as taxable, both produce a wrong return. This is why accounting for healthcare practices has to be set up for the specific mix of services.

Where healthcare HST goes wrong: Claiming ITCs against exempt income, missing registration on a growing taxable stream, mislabelling cosmetic or medical-legal work as exempt, and failing to apportion expenses in a mixed practice. Each one is a reassessment risk, and each one is avoidable.

Case Study: Family & Aesthetics Clinic, Ontario

A family clinic that had added a cosmetic injectables service came to us treating all of its revenue as exempt and claiming no HST anywhere. The cosmetic stream had grown past the registration threshold years earlier. We registered the clinic for the taxable activity, set up proper apportionment so HST was charged only on the cosmetic services, claimed input tax credits on the expenses tied to that stream, and brought the back-filings current under a relief request. The clinic became compliant and recovered ITCs it had been leaving on the table on its taxable side.

Registered correctly, apportioned, ITCs recovered on the taxable stream.

Frequently Asked Questions: HST-Exempt Healthcare Services in Ontario

Are doctors' services exempt from HST in Ontario?

Yes. Most services a physician provides to a patient are exempt from HST, so doctors generally do not charge the 13% tax on core medical care. Some services, such as cosmetic or third-party report work, can be taxable. Healthcare Accounting →

What does HST-exempt actually mean?

It means you do not charge HST on the service, and you generally cannot recover the HST you pay on related expenses. No tax is collected, and none is recoverable, so the HST on your costs becomes a permanent expense.

What is the difference between exempt and zero-rated?

Both mean no HST is charged to the customer, but with zero-rated supplies you can still claim input tax credits, while with exempt supplies you cannot. Zero-rated is the more favourable category. Exempt vs Zero-Rated →

Can a medical clinic claim input tax credits?

Generally not against exempt revenue. Because exempt services do not charge HST, the HST paid on related expenses cannot be recovered. A clinic with a taxable stream can claim ITCs only on the expenses tied to that taxable activity.

Are dental services HST-exempt?

Most dental services provided to a patient are exempt. Purely cosmetic dentistry and certain product sales can be taxable, so a dental practice often has a mix that needs careful treatment.

Are physiotherapy and chiropractic services exempt?

Services of many regulated health professionals, including physiotherapists and chiropractors, are generally exempt when rendered to a patient. The exemption depends on the service being a recognized health service, which we confirm for your specific practice. Chiropractor Accounting →

Are cosmetic procedures taxable?

Generally yes. Procedures performed purely for appearance rather than a medical purpose are usually taxable at 13% HST, even when a physician or dentist performs them. This is one of the most common taxable streams in a health practice.

Are medical-legal reports taxable?

Many are. Independent medical examinations and reports prepared for third parties such as insurers or lawyers are often taxable rather than exempt, because they are not treatment provided to a patient. Each arrangement should be reviewed.

Are prescription drugs and medical devices exempt or zero-rated?

Many prescription drugs and certain medical devices are zero-rated rather than exempt, which means no tax to the customer but input tax credits are available. The category matters because zero-rated allows ITC recovery.

My practice only does exempt work. Do I register for HST?

Generally no. A practice making only exempt supplies does not register, because it makes no taxable supplies. You only need to register once you have taxable supplies over the threshold.

When does a health practice have to register for HST?

When taxable supplies exceed the small-supplier threshold over four consecutive calendar quarters. The test looks at your taxable revenue, not your total revenue, so a mostly exempt clinic can still have to register for a growing taxable stream. GST/HST Filing →

What is a mixed practice for HST?

It is a practice that earns both exempt and taxable revenue, such as a clinic offering both medical care and cosmetic services. Mixed practices must charge HST on the taxable part and apportion expenses for input tax credits.

How does expense apportionment work?

In a mixed practice, expenses are allocated between exempt and taxable activities. Input tax credits can be claimed only on the portion of expenses that relates to taxable supplies, using a reasonable and documented method.

What happens if I claimed ITCs I was not entitled to?

The CRA can reassess and require repayment with interest. Claiming input tax credits against exempt revenue is a common error in health practices. We can review prior filings and correct them, often through a relief request.

If I cannot recover HST, how should I price my services?

Non-recoverable HST on your rent, equipment and supplies is a real cost, so it should be built into how you cost and price the practice. Treating it as recoverable understates your true costs.

Are services billed to OHIP exempt?

Insured physician services funded through OHIP are part of the exempt healthcare framework, so HST is not charged on them. The exemption analysis still matters for any services outside the insured framework.

Are services to insurers or employers exempt?

Often not. When the service is a report or assessment for a third party rather than treatment of a patient, it is frequently taxable. The recipient and purpose of the service drive the treatment.

Do allied health professionals charge HST?

It depends on the profession and service. Many regulated allied health services are exempt when provided to a patient, while non-regulated wellness services are often taxable. Each service line should be assessed.

Are massage therapy services taxable?

The treatment of registered massage therapy has specific rules and has changed over time, so it should be confirmed against the current legislation rather than assumed. We verify the current position for your practice.

Are naturopathic or wellness services exempt?

Many non-regulated wellness, naturopathic and aesthetic services are taxable rather than exempt. The exemption generally applies to recognized health services by regulated professionals, so wellness offerings often fall on the taxable side.

Do I charge HST on retail products I sell in my clinic?

Usually yes. Selling skincare, supplements or other retail products is a taxable supply, separate from your exempt services. Product sales are a common reason a clinic crosses the registration threshold.

I rent space to another practitioner. Is that taxable?

Renting space or equipment to another practitioner is generally a taxable supply, not exempt healthcare. This is an easily missed taxable stream that can require registration.

Does incorporating change the HST treatment?

No. Whether you operate personally or through a medical professional corporation, the HST treatment follows the nature of the service, not the structure. Exempt services stay exempt either way.

How does HST interact with my corporate tax?

They are separate. HST is a transaction tax on supplies, while corporate tax applies to profit. Non-recoverable HST simply increases your expenses, which lowers profit and the tax on it. We handle both together.

What records do I need for healthcare HST?

Keep clear records separating exempt and taxable revenue, the expenses tied to each, and the HST charged and paid. Good records are what make apportionment and any CRA review straightforward.

What triggers a CRA review of healthcare HST?

Claiming ITCs against exempt income, inconsistent treatment of cosmetic or report work, and a taxable stream that should have been registered are common triggers. Correct, documented treatment is the best protection.

My clinic has both exempt and taxable income and never registered. What now?

We assess when registration should have started, register the practice, set up apportionment, and bring the back-filings current, often with a relief request to reduce penalties. It is a fixable situation.

Are your fees inclusive of HST?

Yes. All quoted fees include HST, so the number you are quoted is the number you pay. Payment is by Interac e-Transfer to info@gondaliyacpa.ca, with auto-deposit enabled so no security question is needed.
