Deductions & credits

The spouse who paid it can deduct it, or you can split it.  However, if you live in a Community Property State then it is all split 50/50.  Also, when you file as Married Filing Separately, if one spouse itemizes on Schedule A, the other must also itemize on Schedule A.

Is it better for a married couple to file jointly or separately?
