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.
