Starting Feb. 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, in Notice 1036, on Jan. 9, 2018. The notice contains early release copies of the “Percentage Method Tables for Income Tax Withholding” that will appear in IRS Publication 15 (Employer’s Tax Guide).
According to the IRS, Notice 1036 is the first in a series of steps that the agency will take to help employers improve the accuracy of their tax withholdings under changes made by a new tax reform law, the Tax Cuts and Jobs Act, enacted on Dec. 22, 2017.
Employers should become familiar with the new tables and begin using them as soon as possible, but no later than Feb. 15, 2018. Employers should also monitor the IRS’s Notice 1036 website for future guidance regarding income-tax withholding under the Tax Cuts and Jobs Act.
