Physiotherapy treatment is HST-exempt, but a physio clinic’s books still need to separate exempt treatment income from taxable income such as medico-legal reports and product sales, record gross billings per practitioner instead of net deposits, and keep the clinic side of every associate split visible. Books that skip those jobs misstate your revenue and can hide a growing HST registration obligation.
Physiotherapy clinic bookkeeping looks simple from the outside. Treatment is exempt from HST, so there is no tax to collect, and it is tempting to run the practice off a bank feed and a year-end shoebox. The clinics that do usually discover at tax time that the numbers they steered by all year were wrong.
Exempt does not mean simple
Physiotherapy delivered by a licensed physiotherapist is exempt under the federal Excise Tax Act. Two things follow. You charge no HST on treatment, and you claim no input tax credits on the expenses behind it, so the 13 percent you pay on rent, software, and equipment stays a real cost. Your books should carry those expenses at their full tax-included amounts. A bookkeeper used to taxable businesses will often set up HST accounts that strip the tax out of expenses, which quietly understates your costs and overstates your profit all year.
Separate exempt income from taxable income
The most important habit in physio practice accounting is splitting revenue by HST treatment the day it is earned, not at year end. Treatment income is exempt. A surprising amount of what a busy clinic earns is not.
Patient treatment
Assessments and treatment provided by a licensed physiotherapist, billed to the patient or their extended health plan. No HST charged, no input tax credits claimed.
Third-party work and products
Medico-legal reports, insurer assessments and file reviews, expert testimony, and retail products like braces and exercise bands. HST applies once the clinic is registered.
The taxable side has its own threshold: once those sales pass $30,000 over four consecutive calendar quarters, registration stops being optional. Exempt treatment income never counts toward that line, which is why the books have to keep the two streams apart. A clinic that lumps everything into one income account cannot tell how close it is getting. We cover the two-stream problem in our guide to mixed exempt and taxable clinic income.
Your deposits are not your revenue
Booking platforms and card processors pay out in lump sums, net of their fees, on their own schedule. If the books record those deposits as revenue, you are understating income and expenses at the same time, and no deposit will ever match a day’s billings. Proper physiotherapy clinic bookkeeping records gross billings by practitioner and by payer, books the processing fees as an expense, and reconciles the payouts against both. That structure is what holds up in a CRA review, and it is the only way to see what each practitioner actually produced. The mechanics get their own guide: why your Jane payouts never match your revenue.
Associate splits need their own ledger
If associates work in your clinic on a percentage split, the books need to show each associate’s gross billings, the clinic share, and what the agreement says that share pays for. The wording matters more than most owners realize. A genuine share of the exempt treatment fee attracts no HST, while a fee charged for rooms and admin support is taxable even though the therapy itself is exempt. Books that only record the net transfer make it impossible to prove which arrangement you have. The full trap is laid out in our comparison of associate and employee costs.
What clean books buy you
Month-end numbers you can trust change real decisions. They show revenue by practitioner and by room, so you know who is profitable and when there is capacity to add someone. They keep the taxable stream visible before it becomes a registration problem. At year end, they are the difference between a smooth filing and paying your accountant to reconstruct twelve months of guesswork.
Common questions
Do I need bookkeeping software, or is a spreadsheet enough?
A solo physio with one income stream can get by on a spreadsheet for a while. Once you add an associate or start earning taxable income, a proper ledger with separate income accounts earns its keep, mostly by preventing the errors above.
Can my receptionist do the books?
Day-to-day coding, yes. The setup is where clinics get hurt, because the chart of accounts decides how exempt and taxable income are separated and how splits are recorded. Have the structure built by someone who knows physio HST rules, then let your team run it.
How often should the books be reconciled?
Monthly. The taxable-sales threshold is measured over rolling quarters, and processor payouts drift constantly, so a clinic that reconciles once a year finds every problem eleven months too late.
