Federal income tax withholding

How it works

1. 1

   Enter the employee's W-4

   Filing status, the Step 2(c) multiple-jobs checkbox, Step 3 dependents credit, and Step 4(a) other income and 4(b) deductions — exactly as they appear on the 2020-and-later Form W-4.

   

2. 2

   Employees can update it themselves

   An employee can request a W-4 change from their own login; it only takes effect once you approve it.

   

3. 3

   Withheld on every run

   The Fed. tax column on each run is the full Worksheet 1A result for that employee and pay period.

   

4. 4

   The tables behind it

   The current withholding tables are on the Tax rates page, with a link to the official IRS source.
