Education tax credits can help offset the costs of higher education for yourself or a dependent. The Hope Credit and the Lifetime Learning Credit are two education credits available which may benefit you. Because they are credits rather than deductions, you may be able to subtract them in full, dollar for dollar, from your federal income tax.
