W4 forms, also known as Employee’s Withholding Allowance Certificate, are used to determine the amount of federal income to be deducted from an employee's paycheck.
You can download the federal W4 forms here. Your employee will need to fill out the federal form and submit them to you so that appropriate deductions can be taken from their paycheck. The deducted taxes are then remitted to the government on the employee's behalf by you, or you can authorize Wave to submit your payroll taxes for you if you are in a Tax Service supported state.
When you add an employee to Wave, we will fill in the default deductions or you can navigate to Employees > Tax Details to fill in the deductions according to your employee’s W4.
