2020 W-4 Form - Federal Withholding

The IRS 2020 W-4 Employee Form provides the Federal Withholding information required for new hires and any current employee with W-4 filing status changes made after January 1, 2020. This information includes the employee's filing status, working multiple jobs calculation (including their working spouse), child tax credit, and other income that determines the standard deduction and tax rates used to compute withholding amounts.


According to the instructions for completing the 2020 W-4 provided by the IRS, employees are required to complete their personal information in Step 1 as well as completing the signature section in Step 5.



Steps 2 – 4 are completed only if they apply to the employee. Employees using these steps will follow the form instructions to include additional information for their withholding calculation.
