Where a non-resident makes a taxable supply of, say, a service to a Canadian registrant and mistakenly fails to charge GST/HST due, for instance, on the mistaken belief that it was not carrying on business in Canada, the Canadian recipient would typically self-assess itself for GST/HST under ss. 218 and 218.1 if it did not acquire the service exclusively in the course of its commercial activities. If CRA subsequently assessed the non-resident for failure to charge GST/HST on the basis that the place of the supply was in Canada, would CRA accept evidence that the recipient self-assessed itself for the GST/HST as satisfying the obligation to remit GST/HST on the supply?
CRA responded:
A recipient of a taxable supply made in Canada by a registrant is not required to self-assess Division IV tax under section 218 or 218.1. If the recipient self-assesses the tax, it has done so in error.
Where a recipient has self-assessed Division IV tax in error, the recipient may be eligible to claim a rebate of the tax, pursuant to section 261, provided the amount was not assessed under section 296. A section 261 rebate for tax paid/remitted in error can be claimed within two years after the day the amount was paid/remitted. Where a rebate under section 261 is restricted or is outside the two year period, the recipient may request a (re)assessment of the applicable return for the particular period.
