As we near the end of 2017, there are a number of legislative changes that are pending resolution in the House and Senate. As a result, the Internal Revenue Service (IRS) will not make any changes to the 2018 percentage-method withholding tables and Form W-4 (Employee Withholding Allowance Certificate) at this time. Employers are advised to continue using the 2017 withholding tables until the IRS issues further guidance. ADP Resource is monitoring the situation and will provide further communication and system updates upon final determination from the IRS.
