Yes, you can. However, for most people, it works out best to file jointly as many deductions and credits are not allowed when Married Filing Separately. 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?
