Final answer:
Alan's parents cannot claim him as a dependent on their return if he earns over $3,950. Even if his parents can claim him as a dependent, Alan can still claim a personal exemption for himself.Therefore, the correct answer is option a. Only statement I is correct.
Step-by-step explanation:
To determine whether Alan's parents can claim him as a dependent on their return, we need to consider two statements: I. Because he earns over $3,950, his parents cannot claim him as a dependent on their return. II. Alan cannot claim a personal exemption for himself if his parents can claim him as a dependent.
Statement I is correct. The IRS has a rule that states if an individual earns more than the threshold amount, which for 2020 is $4,200, they cannot be claimed as a dependent on someone else's tax return.
Statement II is incorrect. Even if Alan's parents can claim him as a dependent, he can still claim a personal exemption for himself if he meets certain criteria. However, the personal exemption has been suspended for tax years 2018-2025 due to changes in tax laws.
Therefore, the correct answer is option a. Only statement I is correct.
