I have been doing the books for a friend for the last 4 years, he was leaving and working in BC, Canada, so it was easy, but for 2012, he was working in Alberta while keeping his residence in BC. He has a business in drywall finishing. By what I know about bookkeeping, I would guess that he can claim his share of the rent and utilities in Alberta as business expenses because he is there only for business purpose, but he thinks that he can also claim the food he buys in Alberta as expenses which I really don't think so because that he leaves in Alberta or in BC he has to eat. I need some help to clarified if he can or can't claim those expenses and at which rate can he do it?
Thank you for your help.
