People continue to seek ways to save money when sending their children to college. Some expenses can't be avoided however, you can recoup those costs through lowering your taxes.
College textbooks are a qualified educational expense for tax purposes. The actual cost of the book can be deducted from the gross income which will reduce the students tax liability.
A situation may arise where the new ebooks are being pushed for college. These books are considered rentals and may or may not qualify for the same amount of tax right off. Certainly one would expect to be able to deduct the rental expense.
If you later resell your college textbooks, you may be found liable for the tax on the purchase price recovered after the sale.
