Ontario Online HST Registration Filing Service $39.99...
The Ontario harmonized sales tax combine the eight percent provincial sales tax with the five percent federal goods and services tax (GST) to create a single 13 percent harmonized sales tax (HST) administered by the federal government.
The HST is now in effect in Ontario. It is applied on most purchases of taxable supplies of goods and services in Ontario at a rate of 13%, consisting of the 5% federal portion and an 8% provincial portion.
Businesses in Ontario that were registered for GST are now required to collect and report the HST according to their previous GST filing frequency.
If you are already registered for GST, no further registration is required. If you are not required to register for GST, you do not need to register for HST. New businesses will need to register for HST unless they are Small Suppliers and choose not to. Even if you are a Small Supplier, however, you may voluntarily register your small business, enabling you to claim Input Tax Credits.
As a HST registrant, you charge 13% on the taxable goods and services (other than zero-rated) you sell, lease, transfer, or provide in some other way.
You have to register for GST/HST if:
you provide taxable goods and services in Canada; and
you are not a small supplier.
You do not have to register if:
your only commercial activity is the sale of real property, other than in the course of a business (although you do not have to register for the GST/HST in this case, your sale of real property may still be taxable and you may have to charge and collect the tax).
