I haven't yet advised client how to set up auto-enrolment scheme because we've only just applied for a payroll scheme, and she's not heard from HMRC yet about the scheme details. So if this is still the case when I run her first payroll, I clearly can't make any deductions. I would have had to make sure employees were informed about the scheme first, and deducting for a non existent scheme sounds fraudulent to me.
So I can only start deductions for AE when a scheme has been set up and that can only be done when the payroll scheme numbers are known. Do you agree?
