A not-for-profit corporation registered for GST/HST purposes effective March 18, 2016, then got this registration backdated somewhat to January 1, 2016 – and then subsequently filed returns for the previous six years (2010 through 2015) and requested that its registration be further backdated to April 1, 2010 in order that it could claim input tax credits for tax paid since April 1, 2010. The Directorate stated:
In order to backdate its registration, [Corporation A] could show it was a registrant during the period in question by proving it was not a small supplier; in other words, it was required to be registered.
The Directorate did not reference any limitation on claiming ITCs from before the four-year period referenced in ETA s. 225(4)(b), and instead stated:
Generally, a person who is registered for the GST/HST is entitled to claim input tax credits for the tax paid or payable by them on inputs that are used, consumed, or supplied in the course of its commercial activities. Where property or a service is consumed or used partly in the course of a person’s commercial activities and partly in its non-commercial activities (less than 90%, but more than 10% in its commercial activities), the person must apportion the GST/HST for the property or service between these two activities.
