The Internal Revenue Service (IRS) has released the NEW 2020 Form W-4, Employee’s Withholding Certificate, it is very different from previous versions. This is due to the federal tax law changes that took place in 2018.
The IRS is not requiring all employees to complete the revised form and has designed the withholding tables so that they will work with both the new and prior year forms. Please note: if you do not submit a new form, withholding will continue based on your previously submitted form.
More information can be found at Payroll Forms under the Tax Forms section.
