199. Where property or a service is acquired or brought into Québec by a registrant for consumption, use or supply exclusively in the course of commercial activities of the registrant, the input tax refund of the registrant in respect of the property or service for a reporting period of the registrant is the amount of any tax that became payable or, if it had not become payable, was paid by the registrant in that period in respect of the acquisition or bringing into Québec by the registrant of the property or service.
For the purposes of this section, where an invoice for an amount is issued to a registrant in respect of a taxable supply made in Québec to the registrant, tax under section 16 calculated on that amount is deemed to have become payable on the date of the invoice.
