Final answer:
To calculate the tax withheld, one would need to consider the annual income, use relevant tax brackets, include Social Security and Medicare deductions, and estimate federal and state taxes, which could be around 15% of gross income.
Step-by-step explanation:
The amount of tax withheld from a single employee's paycheck earning $3,215 per month and claiming zero withholding allowances depends on current tax rates and policies. To determine the amount, you would need to reference tax tables or use tax software. However, in a general way, the employee's annual income would be calculated first ($3,215 x 12 months = $38,580). Following the example provided, if we suppose the taxable income falls into a similar tax bracket and method of calculation, a portion of the income would be taxed at a base rate (e.g., $837.50 from the example table) plus a percentage of the income over a certain threshold (e.g., 0.15 × ($38,580 - threshold)). Additionally, Social Security deductions, which is 6.2% of gross annual income, and Medicare, which is 1.45% of gross annual income, need to be considered along with the federal and state taxes, potentially estimated at 15% of gross income, as in one of the examples provided.
