One registration, fully set up
Handled here
Ontario combines GST and provincial sales tax into one HST rate, which means one registration instead of two separate tax accounts. The $30,000 small-supplier threshold works the same way it does for GST elsewhere in Canada.
We register new and growing Mississauga businesses for HST, securing a Business Number where needed and explaining whether voluntary registration below the threshold makes sense.

HST Account & BN Registration
We handle both mandatory and voluntary HST registration, securing your Business Number through CRA's Business Registration Online system if you don't already have one.
Why Work With This Team
Ontario-specific setup
HST registration works differently from separate GST/PST registration in other provinces. We handle it the way Ontario requires.
Business Number handled for you
If you don't have a BN yet, we secure it as part of the registration, not as a separate delay.
Registered and filing correctly from day one
We don't stop at registration. Your first return gets filed on the right schedule too.

Frequently Asked Questions
What's the HST rate in Ontario?
13%, combining the federal GST with Ontario's provincial portion into a single rate.
Do I need a Business Number before I can register for HST?
You need one to register, but if you don't have it yet, it gets secured as part of the HST registration process.
What happens if I don't register once I hit the threshold?
You're still liable for HST you should have collected, plus potential penalties, even without registering.
