Physiotherapist tax services: running a clinic that is half exempt, half taxable
Physiotherapy delivered by a registered PT is HST-exempt no matter who pays — OHIP, an auto insurer, a private plan, or the patient. But the modern clinic rarely sells only physiotherapy. Kinesiology sessions, massage therapy, exercise classes, and braces are taxable. That turns many clinics into mixed suppliers, with HST on some invoices and input tax credits that must be split. We keep the two halves apart and the T2 or T2125 behind them clean.

The exemption follows the physiotherapy, not the clinic
A physiotherapist registered with the College of Physiotherapists of Ontario provides a GST/HST-exempt service to an individual. The payer is irrelevant here. An OHIP-funded episode at a community clinic, an auto-insurance claim billed through HCAI, an extended-health visit, and a cash session are all treated identically. Delivery mode is just as irrelevant — a virtual session with an Ontario patient carries the same exemption as one on the treatment table. What the exemption does not do is spread to the rest of the menu. It covers the professional service of a physiotherapist — so revenue earned by other people, or from other things, has to be tested on its own.
What is taxable in a typical physio clinic
The taxable lines are the ones that surprise owners, because they sit right beside exempt work on the same day sheet:
| Clinic revenue line | Exempt or taxable |
|---|---|
| Physiotherapy assessment and treatment by a registered PT | Exempt, whoever pays |
| Kinesiologist-delivered sessions sold as their own service | Taxable — kinesiologists are not on the exempt practitioner list |
| Massage therapy offered in the clinic | Taxable — massage remains outside the exemption |
| Group exercise classes, gym access, braces, bands, and retail | Taxable |
| Assessments and reports prepared solely for an insurer or lawyer | Generally taxable — not a qualifying health care supply |
Only the taxable rows count toward the $30,000 small-supplier threshold measured over four consecutive calendar quarters. A solo PT selling nothing but treatment may never register; a multidisciplinary clinic with two RMT rooms and a kin program almost certainly must.
Mixed-supplier mechanics: charge on some lines, allocate on all costs
Once registered, the clinic charges 13% only on taxable lines. Then the real discipline starts, because input tax credits follow the use of each cost. HST on massage-room supplies is fully creditable. HST on costs serving the physiotherapy side is not creditable at all. Shared costs that carry HST — rent, software, utilities, cleaning — are apportioned on a fair and reasonable method applied consistently, usually revenue-based or floor-space-based. The apportionment is only defensible if invoices and the chart of accounts separate the lines all year. So we set that structure once, and the quarterly GST34 filings become mechanical. Capital equipment runs on a blunter rule. For capital personal property like a shockwave unit, primary use decides everything. A machine used mostly on taxable lines earns a full ITC, while one used mostly for physiotherapy earns none. Getting it wrong runs in both directions. Clinics that claim full ITCs over-recover and build an audit liability. Clinics that claim none quietly donate thousands back to the CRA instead.
The professional corporation and the overhead it shelters
Physiotherapists can incorporate a health profession corporation with a certificate of authorization from the College. Shares are restricted to members of the profession — no spousal shareholders. So the value is deferral, not splitting. Practice profit retained in the corporation is taxed at about 12.2% in Ontario, up to the $500,000 small business limit. That is precisely the cheap capital a clinic build-out consumes. Treatment beds, shockwave and ultrasound units, and gym equipment sit in Class 8 at 20% declining balance, with leaseholds in Class 13 over the lease term. Remember that HST the clinic could not recover on the exempt side forms part of an asset's capital cost and depreciates with it. An unincorporated PT or a contractor working across clinics reports on a T2125 instead. They deduct College registration, association dues, liability insurance, and courses. Quarterly instalments arrive once net tax passes $3,000.
Contractors, associates, and where the border creeps in
Clinic rosters mix employees, self-employed associates on splits, and contractors who float between clinics. The label has to match the working reality. A reclassified associate means retroactive CPP, EI, and penalties for the clinic. We review the agreements against how shifts, tools, and patients actually flow. And physiotherapy has a genuinely mobile profession on the US side. Travel-PT contracts on TN status, US continuing education, and American recruiting pitches raise residency and withholding questions that a domestic return never sees. That terrain is mapped on our cross-border tax page for physiotherapists, with the broader engagement described under our tax services.

Common questions.
Is physiotherapy subject to HST?
No — physiotherapy rendered to an individual by a registered physiotherapist is exempt, whether OHIP, an insurer, or the patient pays. Taxable lines like kinesiology sessions, massage, classes, and retail are what trigger registration.
How do input tax credits work in a mixed clinic?
HST on costs tied to taxable lines is fully creditable. HST tied to exempt physiotherapy is not. Shared overhead is apportioned on a fair and reasonable method used consistently. Clean invoicing and account coding are what make the split defensible.
Should a physiotherapist incorporate?
Only when profit reliably exceeds what you draw for living costs. Ontario restricts PC shares to physiotherapists, so the benefit is deferral at roughly 12.2% rather than income splitting. Below that point a T2125 practice is simpler and usually cheaper.
