T2125 Business Use of Home amounts for small business question

[gcolquhoun]

My wife and I are filing jointly. I work full time and she has a small home based business where she made around $13K in 2016. This obviously means that I pay the vast bulk of the mortgage/bills/etc. Question is, can we claim the full amount on things like Interest Paid on Mortgage, Utilities etc? Or should it be somewhat proportionate to her income? I think the answer is the full amount, but just looking for a little clarification.

Thanks in advance.

Thank you for your question. It does not have to be proportioned to her income. The proportion that does occur is office space vs total home space, which will prorate the total expenses to the amount related to the business.
