For most taxpayers, you need to receive Form 1098-T in order to claim the American Opportunity Credit or Lifetime Learning Credit. You can take the Education Deduction without Form 1098-T.
What if I don't have a 1098-T?
If you don't have a 1098-T but you know the amount of tuition paid to the college you can enter that amount on the Additional Tuition Expenses screen.
