Do we consider our 23 yr old son a family member on FAFSA if we don't claim as exemption on return?

But @vgulian should consult a tax professional because she may need to file a gift tax return if the amount of support* provided to her adult child who is not a dependent for tax purposes is more than $14k/year (or $28k/year if gift-splitting with spouse).

*food, clothing, rent, medical insurance, etc.
