Why some of my payroll list items are being exempt from taxes, why and where to change or correct?

Removing the tax-exempt status is my specialty, userpsylvester. I'll gladly show you the way.

In QuickBooks Online, we can go to the Tax Exemptions section to remove the taxes. Here's how:

1. Go to the Payroll menu proceed to the Employees tab.
   
2. Locate and click the name of the employee.
3. On the Tax withholding section, click the pencil icon.
   
4. Scroll down to Tax exemptions, uncheck the Social Security and Medicare box.
   
5. Once done, click on Save.
