If we have an employee who is under the age of 18, should we check off the tax exemptions section for them (CPP, EI, Federal)?

Hi useraccounts46,

I appreciate you reaching out here.  Welcome to Community!  It's vital that you're aligned with government guidelines, when setting up QuickBooks Online Payroll and tax exemptions for your employees.  Please follow this link to learn more about payroll deductions and contributions.  If you have additional questions or concerns, I recommend speaking with an accounting professional.  If you don't have an accountant, we can help you locate a ProAdvisor in your local area.

Feel free to reach back out with other questions.  We'd be happy to assist!
