Well for sure the full HST is an ITC and I'm required to charge 15% HST on sales I make to NS, NB, and N&L. AFAIK, it isn't a blended federal and provincial tax, it's a federal tax some of which is turned over to the province.

Not totally clear on the TVQ, parnel are you saying it's claimable as an ITC? I read the whole 48pp PDF on the CCRA (Revenue Canada, not Reform Party) site and it only referred to GST and HST. This isn't a big amount but I'll be in Montreal this weekend so if I can make the purchase at Future Shop there, it will save me $10 or so if I can claim the TVQ.

Thanks!
