If you are an employee who receives a paycheck from your employer, it is important to make sure that your tax withholding information is up to date in ADP. This is because the amount of taxes that are withheld from your paycheck is based on the information that is stored in ADP. If your tax withholding information is not up to date, you may end up owing taxes at the end of the year or receiving a smaller refund than you expected. Knowing how to update your tax withholding information in ADP can help you ensure that the right amount of taxes are being withheld from your paycheck.
