You can claim it all unless you live in a community property state. If so, you have to split it 50/50 on your individual tax returns. 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?
