  • Changes to your Tax Status (Married, Single, Head of Household, Exempt) are not allowed. You must update your Federal W-4 in the employee portal to make this change.
  • If you have not updated your Federal W-4 since 2019, you must update the form first.This will ensure your federal taxes are calculating per the IRS W-4 revisions issued in 2020.
  • Changes to your Federal W-4 will result in the CO Annual Withholding Allowance defaulting to the federal standard deduction.
