Final answer:
Sheryl's tax liability depends on her age and the type of income she received. Since Sheryl is 16 years old at year-end, she would not owe any federal income tax for scenarios a, b, and d, as her income falls below the threshold. In scenario c, even though Sheryl is 20 years old, she would still not owe any federal income tax.
Step-by-step explanation:
a. Since Sheryl received $9,200 from a part-time job and this is her only source of income, her tax liability for the year would depend on her age. Since she is 16 years old at year-end, her earned income falls below the standard deduction for a single filer ($12,550 in 2021). As a result, she would not owe any federal income tax.
b. Similarly, since Sheryl received $9,200 of interest income from corporate bonds, which is her only source of income, her tax liability would depend on her age. Since she is 16 years old at year-end, her unearned income falls below the threshold for filing a federal income tax return. Therefore, she would not owe any federal income tax.
c. Even though Sheryl is a full-time student at 20 years old, her tax liability for the year would still be zero. The $9,200 interest income she received from corporate bonds is her only source of income, and it falls below the standard deduction for single filers ($12,550 in 2021).
d. If Sheryl received $9,200 of qualified dividend income as her only source of income, her tax liability would depend on her age. Since she is 16 years old at year-end, her unearned income falls below the threshold for filing a federal income tax return. Thus, she would not owe any federal income tax.
