Q: Can a payroll office or human resources department help someone understand these tax law changes or use the Withholding Calculator?

A: It is an employee’s responsibility to check their withholding and determine if it’s accurate for their personal situation. Payroll offices and human resource departments are responsible only for processing the Form W-4. The people working in these offices do not know the rest of someone’s personal financial situation, and they are not responsible for giving you tax advice.

Q: Does it make any difference when an employee checks on their withholding?

A: Sooner is better. Withholding takes place throughout the year. If an employee needs to adjust their withholding, doing so as quickly as possible means there’s more time for tax withholding to take place evenly during the rest of the year.
