2020 Form W-4 Information

The Internal Service (IRS) released a revised Form W-4 for 2020 and added a new tax table. With these changes, the Office of the State Auditor (OSA) has updated the CTAS Payroll Module to meet the Federal Guidelines (CTAS update to include this information was released on June 16, 2020).

If using a version of CTAS earlier than CTAS 2020, entities/employers who withhold Federal income tax will need to manually calculate the federal income tax for employees who submit a 2020 or later Form W-4. IRS Publication 15-T provides a worksheet that can be used when calculating federal income tax (Use the Percentage Method Tables for Automated Payroll Systems). Current information about publication 15-T and Form W-4 can be found on the IRS website at:
