Physiotherapist tax services: running a clinic that is half exempt, half taxable

The exemption follows the physiotherapy, not the clinic

A physiotherapy service rendered to an individual by a physiotherapist registered with the College of Physiotherapists of Ontario is exempt from GST/HST, and the payer is irrelevant: 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:

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 — and 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; and 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, so 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, while clinics that claim none quietly donate thousands back to the CRA.

The professional corporation and the overhead it shelters

Physiotherapists can incorporate a health profession corporation with a certificate of authorization from the College, and 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, which 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, deducting College registration, association dues, liability insurance, and courses — with quarterly instalments arriving 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 — and the label has to match the working reality, because 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.
