Hello, Office331. Since the employee is exempt from Employment Insurance (EI), we need to update their payroll setup to prevent future discrepancies in their paychecks.

Here's how:

1. Open your QuickBooks.
2. Go to Payroll, then select the Employee.
3. Under Profile, select the Edit option in the Tax withholdings.
4. Under Tax exemptions, put a check mark on the Employment Insurance.

For now, to correct the payroll error for the last four pay periods, I recommend contacting our Live Support team to do payroll corrections in QuickBooks. Here's how to reach them:

1. Open your QuickBooks.
2. Click the Help icon in the upper-right corner of your screen.
3. In the Search bar, type Contact Us.
4. Click Contact Us below.
5. Choose the Callback option.
