Final answer:
Elaine can claim the full $2,500 American Opportunity Tax Credit if her AGI is $80,000, as it is below the phase-out threshold. With an AGI of $168,000, she is eligible for a reduced AOTC amount. At $184,000, Elaine cannot claim the AOTC as her income is above the phase-out limit.
Step-by-step explanation:
In the scenario provided, Elaine's eligibility for the American Opportunity Tax Credit (AOTC) depends on her adjusted gross income (AGI) level. For 2022, the AOTC allows eligible taxpayers to claim a credit for qualified education expenses paid for an eligible student, but the credit amount begins to phase out for taxpayers with higher incomes.
If Elaine's AGI is $80,000, she may claim the full AOTC since her income is below the phase-out threshold for married couples filing jointly, which starts at $160,000. The maximum AOTC per student is $2,500, which comprises 100% of the first $2,000 of qualified education expenses and 25% of the next $2,000. Therefore, Elaine can claim $2,500 for the $2,800 tuition and $600 books, as these amounts exceed the $4,000 threshold to maximize the credit.
However, with an AGI of either $168,000 or $184,000, Elaine's claim would be subject to a phase-out or not available at all. At $168,000, she would only be eligible for a reduced AOTC amount. At $184,000, the AOTC would be completely phased out for her, as the phase-out ends at $180,000 for married couples filing jointly.
