Effective February 15, 2018, employers must use new tables to determine how much income tax to withhold from their employees’ paychecks. The Internal Revenue Service (IRS) issued the required, new tables, which reflect changes made by the Tax Cuts and Jobs Act, on January 9, 2018. The IRS also released a revised Form W-4 and a new Withholding Calculator on February 28, 2018 that reflects the changes. This Compliance Bulletin provides links to the new withholding tables, the revised Form W-4, and the updated withholding calculator, as well as additional information about the new tax withholding tools.
