Once your massage therapy revenue passes $30,000 over four rolling quarters, you have to register for HST, start charging it, and file returns. The upside is you also start claiming HST back on your costs. Here is how registering actually works, step by step.
Crossing $30,000 is a good problem to have, but it comes with a deadline most massage therapists do not see coming. This is the plain-English version of what to do, and when.
When you have to register
You can stay a “small supplier” and skip HST until your taxable revenue passes $30,000. The threshold is measured over the last four rolling quarters, not a calendar year. Two situations to know:
- If you creep past $30,000 across four quarters, you have a short grace period before you must register and start charging.
- If a single busy quarter pushes you over $30,000 on its own, registration is immediate, and that sale is already taxable.
Because the timing has teeth, this is something we watch for you, so you register at the right moment and not a month too late.
You can also register early
You do not have to wait for $30,000. If you are buying equipment, paying clinic rent, or investing in your practice, registering early lets you claim that HST back sooner. Whether it is worth it depends on your numbers, and it is a quick conversation to have before you decide.
How to register
Registering is straightforward once you know the order:
- You need a CRA business number. If you do not have one, you get it as part of the same process.
- You open a GST/HST account, online through the CRA, by phone, or with our help.
- You choose your effective date, which is when you officially start charging HST.
- The CRA sets how often you file. For most massage therapists at this level, that is once a year.
What changes the day you register
Three things start at once:
- You charge HST on your treatments, at the rate for the province where you work.
- You claim HST back on your business costs, your rent, supplies, equipment, and more, as input tax credits.
- You file an HST return and send the CRA the difference between what you collected and what you are claiming back.
That credit in the middle is the part most RMTs under-claim. Done properly, registering is not just a cost, it hands real money back to you.
What about physiotherapists?
None of this applies to physiotherapists. Physiotherapy is HST-exempt, so physios never register and never charge HST. This is purely a massage therapy and other taxable-practice question. If you want the bigger picture, read why physiotherapy is exempt but massage therapy isn’t.
Frequently asked
Once your taxable revenue passes $30,000 over four rolling quarters. If a single quarter pushes you over on its own, registration is immediate. Otherwise there is a short grace period before you must register.
Yes. Registering early lets you claim HST back on rent, equipment, and supplies sooner. Whether it is worth it depends on how much you are spending, so it is worth a quick check first.
