90 Minutes

When the IRS overhauled Form W-4 in 2020, it replaced marital status and exemption counts with calculations for second jobs, working spouses and self-employment income. The IRS made the change because it saw a large rise in amounts individual taxpayers owed at year end.

The new design caught many workers and payroll managers off guard, turning simple instructions into a set of projections needed to work out federal and state income tax withholding. This 90-minute Form W-4 training shows you how to help employees complete the form correctly, step by step, using the worksheets, the withholding chart and the related forms.

WHY SHOULD YOU ATTEND?

Under-withholding can cause problems for both employees and employers, and payroll staff are often the first people employees ask for help. This session explains how each W-4 section should be completed for different personal situations and when extra withholding is or isn't appropriate.

You'll also learn which payroll system changes the form required, which current workers should file a new W-4, and which states accept the federal form. It suits payroll, HR, compensation, hiring, finance and executive staff.
