Oakville GST/HST situations we handle
← Swipe to compare →
| Local situation | How we handle it | Source |
|---|---|---|
| Health practices | Many health services are exempt, so no HST is charged and ITCs are limited. Cosmetic or non-medical services can be taxable. We sort each service line. | Excise Tax Act |
| Holding companies | A holdco that only holds shares usually can’t register or claim ITCs. We check before any HST is claimed. | CRA: input tax credits |
| Commercial rent | Commercial rent is taxable once the landlord is registered, unlike most residential rent. We set up the right tax code for each unit. | CRA: input tax credits |
Law: Excise Tax Act Sch. V, Part II (exempt health care services); Excise Tax Act s.169(1) (input tax credits).
How we work with Oakville clients
In Oakville, GST/HST questions often arise from structure rather than volume. A clinic may have exempt and taxable services under one roof, a holding company may hold property or shares, and a consultant may bill clients abroad. Each of these changes whether you should be registered and which ITCs you can claim.
We review your service lines and entities first, then file from reconciled books. Where a business has both exempt and taxable supplies, we allocate shared costs so ITCs are claimed only on the taxable side.
GST/HST rules that apply in Ontario
Oakville businesses follow the same rules as the rest of Ontario: register once taxable sales pass $30,000, charge 13% HST, claim input tax credits with proper receipts and file on your assigned schedule. Thresholds, filing deadlines and penalties are explained on our GST/HST services page.
Law: Excise Tax Act s.148(1), s.240(1); Excise Tax Act s.165.

GST/HST in Oakville: FAQs
Do you file GST/HST returns for Oakville businesses?
Yes. We register Oakville businesses, file returns from reconciled books and answer CRA letters. Our nearest office is in Mississauga, by appointment.
Does my Oakville clinic need to charge HST?
Many health care services are exempt, but some services, such as cosmetic procedures, may be taxable. We review your service list and tell you which applies.
My holding company owns a commercial unit. Does it need a GST/HST number?
If commercial rent goes over $30,000, it must register. Below that it can register voluntarily to claim ITCs on the property.
Can my clinic claim HST on equipment?
Only to the extent the equipment is used for taxable services. We work out the split and claim what is allowed.
