Is there anything I need to do related to the changes made to Form W-4 by the IRS in 2020?

The Internal Revenue Service (IRS) revised and implemented changes to Form W-4, Employee Withholding Certificate, that went into effect on January 1, 2020. As a result, employees with a hire date on or after January 1, 2020, or those who want to adjust their withholding, need to fill out the current Federal Withholding Certificate so that you can input their details into Wave.

If you and/or your employees live in a state that previously allowed the Federal Form W-4 to be used in place of your State Form W-4, you need to check with your state to find out if there are any updates or new requirements.

Do employees hired before 2020 need to fill out the updated Form W-4?

Employees entered in Wave with a hire date prior to 2020 who do not need to make changes are not required to complete a new form and will have withholding calculated based on their previously completed form. If you are setting up payroll in Wave after January 1, 2020, your employees need to complete the updated Form W-4 even if they were hired prior to 2020.

What if my employee doesn’t fill out Form W-4?

Employees hired on or after January 1st, 2020 who do not submit a Federal Withholding Certificate will be treated as a single filer with no adjustments.
