According to the IRS, Pell grants and other need-based educational grants are treated as scholarships for terms of determining taxation; amounts spent on tuition, fees, books, supplies, and equipment (when required of all students) are generally non-taxable for degree candidates. Scholarship funds applied to room/board and travel are taxable. Ref
IRS Publication 970.
In any case, I'd rather spend the income tax due on a grant amount than have to come up with the entire amount of the grant myself.
