Normally, companies with less than $30,000 in revenue do not have to register for HST. However, there is one benefit: Input Tax Credits (ITC). Basically Startups have to pay HST on purchases (‘Input Tax’). The CRA will give a refund (ITC) on those input taxes (HST on purchases) to any registered company.
