Final answer:
No federal income tax will be withheld since the taxable income is negative.
Step-by-step explanation:
To calculate the amount of federal income tax withheld, we need to determine the taxable income. In this case, Alicia's gross pay is $923 and she claims 0 allowances. Single individuals with no allowances have a standard deduction of $12,550 in 2021. So, the taxable income would be $923 - $12,550 = -$11,627.
Since the taxable income is negative, Alicia won't have any federal income tax withheld from her gross pay.
