If have an employer who was on payroll and no longer work here. they are still taking taxes out of my account for this employer?

Removing an employee who no longer works in your company is an easy process.  I'd be glad to give you the right steps, cmdmld8805.

We can terminate the employee in your payroll system to ensure their employment status is updated. This action will stop any additional pay or tax processing from taking place in the future.

To do this, here's how:

1. From the Payroll menu, select Employees.
2. Select the employee and click the Actions dropdown.
3. Click Change status.
4. From the Employment details page, select Terminated. Then, enter the Termination Date.
5. Once done, click Save.

If you want to permanently remove an employee, you can select Delete employee from the Actions dropdown menu. Please note that deleting an employee is irreversible and their data cannot be recovered once deleted.

I've added a screenshot for your reference.

I'm also including this article if need to run payroll reports in the future: Run payroll reports. This includes all the lists of payroll reports available in QuickBooks Online.
