You don't say who your son lives with. Only the parent he lives with for over half the year can claim head of household. But if your son does live with him for over half the year, then he could claim head of household even if you were allowed to claim him as a dependent.Can one parent claim head of household and the other claim as a dependent?
head of household would mean that you have to have a dependant. So basically one of you claims head of household and has your son as a dependant and one of you claims single. Thats the only way to do it.
no but he has to go single or the two of u and baby claim as 1 hoh
