Answer: $2150
Step-by-step explanation:
From the question, Keith has a tax liability of $2,250 and paid $2,600 in qualifying expenses.
The amount of his American Opportunity tax credit allowed will be charged at 100% for the first $2000 and 25% for the next $2000. Since he paid $2600 in qualifying expenses, this will be:
= (100% × $2000) + (25% × [$2600 - $2000]
= $2000 + (0.25 × $600)
= $2000 + $150
= $2150
The amount of his American Opportunity tax credit will be $2150
