American Opportunity Tax Credit. Students may claim this credit if you are over age 24 as long as you meet the other requirements, e.g. are not claimed as a dependent on someone else return, are attending a degree program half-time or more, and have not already completed four years of college.
A key tax credit that helps families pay for college got a major boost in the 2009 stimulus bill. The credit is bigger, covers more years of college, and helps more taxpayers. The American Opportunity tax credit, previously called the Hope College credit, is valued at $2,500 for 2015, up from $1800 in 2008. Because a tax credit reduces your tax bill dollar for dollar, this basically means Uncle Sam will give you up to $2,500 per year for each qualifying college student in your family.
