Special Rule for Married Couples Filing Separate Returns
If you are married filing separately, you and your spouse must both take the standard deduction or you must both itemize your deductions.

As such, it usually makes sense to figure your taxes both ways (each spouse itemizing vs. each spouse taking the standard deduction) to see which will yield the best overall tax savings.
