How do I update an employees birthdate?

Hello aremconcrete-gma,

Welcome to the Community. QuickBooks Online is a versatile program that's designed to help you streamline your payroll. I'll be happy to show you how to update an employee's birthdate in QuickBooks. 

In order to change an employee's birthdate, click on Payroll > Employees > select the employee in question > next to the Profile tab headline, click on the pencil icon > from here you can scroll down to update the employee's birthdate. Make sure your changes are saved once you're done making the changes. 

There you go! You now know how to update an employee's birthdate. Give this a try and let me know how you make out. I'll be one message away in case you have other questions.
