Hello there, @info413.
I'm happy to share the steps on how to opt-out the pension nest in QuickBooks Online (QBO).
To opt-out the pension for the new staff member added, you can simply follow these steps:
- Log in to your QBO account.
- Click on Employees at the left pane.
- Select Employees.
- Look for the employee/staff name.
- Go to the Auto enrolment section and click on the pencil icon beside it.
- Click on the radio button beside Enrolled in pension.
- Select Opt out.
- Click on Done to save the changes.
I've added this screenshot for additional reference.
