Do I need employee date of birth to register them for payroll?

Hello spanjvani-gmail-,

Welcome to the QuickBooks Community, and thanks so much for choosing QuickBooks Online Payroll to manage your payroll data! Making sure you have all the information you need when setting up the payroll module and employee profiles is key, and I'd be happy to go over this with you.

Using the Payroll add-on service in QuickBooks Online, the program will ask you for a number of details about your employee so that it has the information needed to work with things like payroll forms, payroll tax calculations, and so forth. Given that, an employee's birth date is one of the required fields when filling out the What are [employee's] withholdings? in the employee setup. This question acts as the TD1 form that you'd have an employee fill out outside of the Payroll module. If you'd like, you can even invite your employees to set up this kind of information themselves. This article goes over that: Using the Employee Self-Setup feature to add new hires

If you're not using the Payroll module and are simply using the Payroll tab in QuickBooks Online as a reference point for your employee data, the date of birth isn't a required field since the program doesn't need to reference it for any calculations.
