Education

If you'll take a look at the dependency requirements, if your daughter meets all four of those requirements, then you qualify to claim her. Take special note of what is *not* in those requirements. Namely, there is no mention of an income requirement at all. The student could literally earn a million dollars and still qualify as your dependent. The students earnings just flat out do not matter, no way, no how.
" I pay over half of her expenses"
Take note also that there is absolutely no requirement for you the parent to provide *any* support. Not one single penny. The support requirement is on the student, and *only* the student.
