The American Opportunity Tax Credit (AOC) was made permanent by the Protecting Americans from Tax Hikes Act of 2015 (PATH). The maximum credit, available only for the first four years of post-secondary education, is $2,500. You can claim the credit for each eligible student you have for which the credit requirements are met.
Income limits. To claim the American Opportunity Credit, your modified adjusted gross income (MAGI) must not exceed $90,000 ($180,000 for joint filers). To claim the Lifetime Learning Credit, MAGI must not exceed $60,000 ($120,000 for joint filers). "Modified AGI" generally means your adjusted gross income. The "modifications" only come into play if you have income earned abroad.
Amount of credit. For most taxpayers, 40 percent of the AOC is a refundable credit, which means that you can receive up to $1,000 even if you owe no taxes.
Which costs are eligible? Qualifying tuition and related expenses refer to tuition and fees, and course materials required for enrollment or attendance at an eligible education institution. They now include books, supplies, and equipment needed for a course of study whether or not the materials must be purchased from the educational institution as a condition of enrollment or attendance.
"Related" expenses do not include room and board, student activities, athletics (other than courses that are part of a degree program), insurance, equipment, transportation, or any personal, living, or family expenses. Student-activity fees are included in qualified education expenses only if the fees must be paid to the institution as a condition of enrollment or attendance. For expenses paid with borrowed funds, count the expenses when they are paid, not when borrowings are repaid.
Tip: The tax law says that you can't claim both a credit and a deduction for the same higher education costs. It also says that if you pay education costs with a tax-free scholarship, Pell grant, or employer-provided educational assistance, you cannot claim a credit for those amounts.
