Income Tax Withholdings & Mandatory Electronic Remittance of IL W-2’s

Jan 25, 2018

Beginning 2018, income tax withholdings have changed and employers should become familiar with the new Percentage Method Tables for Income Tax Withholdings. Please note there is a separate table for nonresident alien employees. Due to tax reform and income tax rate changes, The Department of Treasury strongly recommends implementing the 2018 withholding tables as soon as possible and no later than February 15, 2018.
