AVC refund

Suggested

We have a situation with an employee who has continued to pay an AVC monthly through payroll since Sept 2020 when this should have been cancelled. We did ask at the time if they wanted to continue.They were not aware that the AVC was connected to the Pension Scheme which the school opted out of from Sept 20.

The contributions have been returned to the school and we now need to account for the tax implications going back to Sept 2020 in order to return the funds to him. I assume that this would need to be done via rollback?

Having not used this before need some guidance on how to do this please.

Thank you
