I believe that your attorney is only partially correct. In certain cases, both separated spouses may claim Head of Household filing status (just as they would be able to do so after dissolution, as single persons). As you probably know, “Head of Household” filing status will typically result in a lower tax bill than filing as Single or, if you are not yet divorced, Married Filing Separately.
Generally, the Head of Household filing status is determined by your custody arrangement. The parent who has the children more than one-half of the year can claim the Head of Household filing status. The only way that both parents can claim Head of Household is if they have more than one child and each parent has at least one different child living with them for more than one-half of the year.
People sometimes mistakenly believe that claiming a child as a dependent entitles them to file as Head of Household. This is not necessarily true. To qualify as Head of Household you must meet the following requirements:
• You must maintain a household for your child (even if you do not claim them as a dependent)
• You must be unmarried at the end of the year or living apart from your spouse for more than six months
• The household must be your home and generally must also be the main home of the qualifying dependent (i.e. they live there more than half the year)
• You must provide more than half the cost of maintaining the household
• You must be a U.S. citizen or resident alien for the entire tax year
You do not need to claim a dependent to file as Head of Household. This means that even if you allow your ex-spouse to claim your child as a dependent, you can still file as Head of Household.
If you can claim Head of Household you may also qualify for the Dependent Care Credit, the Earned Income Tax Credit (for lower income people), as well as other rebates that may be available for that tax year.
