Answer:
C. W-4
Step-by-step explanation:
The W-4 form acts as the Employee’s Withholding Allowance Certificate. The employee completes the form and hands it over to the employer, who uses it to calculate how much income tax to withhold.
The details on the W-4 forms are necessary for tax computation. For instance, the employee declares their marital status and the number of dependents; this determines the applicable tax rates.
