Myself and spouse are separated but still living in the same apartment. We owned a two family home where 1 unit is rented.

She already filed her taxes but did not file schedule E to report her share of the income. We don't live in a community state. My questions is as follows:

1. Do I have to report the entire rental income & expenses or only 50%.

2 I am aware that since we did not live apart, I will not able to deduct any rental loss. Is it possible to use most the entire mortgage interest and property tax amounts on schedule A?

Thanks
