The short answer

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:

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:

What changes the day you register

Three things start at once:

A quick picture
HST you collected from clients$7,800
HST you paid on rent, supplies, equipment$2,300
What you send the CRA$5,500

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.

Keep it separate: the HST you collect is not your income. It is money you are holding for the government, minus your credits. Park it as it comes in and the return is painless. Spend it and the bill stings.

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.

You need a CRA business number, then you open a GST/HST account online, by phone, or with our help. You pick your effective date, and the CRA sets how often you file, usually once a year at this level.

For most massage therapists when they first register, it is once a year. As your revenue grows the CRA may move you to quarterly. We set the schedule up and keep you on it.
