Mortgage and HELOC

[lylejt]

If I file separately from my wife, do we both report the mortgage and heloc on each of our taxes or does it have to be only under one person?

In theory, you divide the interest based on how much each of you paid.  In practice, a married couple can usually say something like "Adam paid 100% of the mortgage interest because Betty paid 100% of other expenses."

So you can put it all on one person or split it any way that seems reasonable to you both.  But do not claim more than the total between you, that would be double dipping.

Ideally, the mortgage interest should be entered in the full amount on the return of the person whose Social Security Number appears on the Form 1098, so that the IRS matching program will find it. 

If you live together in a community property state, you can allocate half of the interest to the return of the other spouse when you complete the community property allocation worksheet. Also, note that if one of you plans to itemize deductions, the other person must itemize as well. Otherwise, you'll both have to use the Standard Deduction. Please see this TurboTax help article for more information.
