Late last week the IRS issued updated withholding tables to conform employee wage withholding to the new tax rates put in place by the Tax Cuts and Jobs Act (you can read more about the TCJA here). The new tables are designed to work with existing W-4s, although the IRS also announced that it is developing a new W-4 for use in future tax years. Employers are required to begin using the new wage withholding tables by February 15, 2018. You can view the new wage withholding tables here.
