2017 IL State Tax Rate

Notice to Employees Regarding the Increase in Illinois Income Tax Withholding effective 7/1/2017:

On July 6, 2017, Illinois legislation was passed to increase the state individual income tax rate from 3.75% to 4.95% effective July 1, 2017. 

 

Prior to the passage of the new income tax rate, AltaStaff withheld at the 3.75% rate as required.  The new 4.95% withholding rate will be implemented with payrolls paid on or after July 13, 2017.  Due to the passage of the increased rate after the July 1, 2017, effective date, you may owe additional income tax next year when you file your 2017 Illinois individual income tax return. 

To update your withholding preferences, please update altastaff.com/ilw4
