How do I hide payroll expenses from other users

Hello there, mickylaw1991-gma.

Primary admins and company admins get all access rights. When you assign the standard user role, QuickBooks lets you choose the user’s access rights. You can choose to give them all access, limited access, or none. While the option to specify them to not only view payroll expenses is unavailable. 

You can use this link for more details in handling user roles: User roles and access rights in QuickBooks Online.

Let me know if you have other questions. Take care and have a great day!
