Can I file Head of household if I am Married

[MichelleT]

You might be able to IF:

if all 5 of these conditions apply:

1. You won't be filing jointly with your spouse; and
2. Your spouse didn't live in your home after June (temporary absences due to illness, school, vacation, business, or military service don't count); and
3. Your home was your child's, stepchild's, or foster child's main home for more than half the year (non-child dependents in your home don't qualify); and
4. You paid more than half the costs of keeping up your home during the tax year; and
5. You meet the qualifications to claim the child as your dependent, even if the other (noncustodial) parent is actually claiming the child as a dependent on their return.

You can also be considered unmarried for Head of Household if your spouse was a nonresident alien at any time during the tax year and you're not treating them as a resident alien.
