Tax withholdings for service members are set up using which data sources?

• A. LES and W-4-equivalent data.
• B. Bank statements.
• C. Annual tax returns.
• D. Employee ID only.

Answer: (A)

Tax withholdings for service members come from two main sources: the Leave and Earnings Statement and the W-4-equivalent form. The LES provides the current pay details and the amount already withheld for federal and state taxes, giving the payroll system a baseline. The W-4-equivalent communicates the member’s withholding allowances and any additional amount they want withheld, which directly drives how much is taken out each paycheck. Together, these data tell the system exactly how much to withhold each pay period. Bank statements show transactions that have already happened and don’t set future withholdings, annual tax returns are filed after the year ends and don’t control ongoing withholding, and an employee ID alone doesn’t provide withholding information.
