My adult son/wife are separated, but not legally. They have lived apart for 16 mos and she is using Head of Household filing status this year and claiming their 3 children as dependents. Is his only option Married filing separately and if she itemizes does he have to do the same? It doesn't look like he has any deductible items, so will he not be eligible for any deductions at all? Does he have any options?
