We have a new employee, aged 21 who earns over the £833 per month. Being 21, he is Non-eligible in terms of auto-enrolment pensions, however, when processing the payroll, Sage has automatically deducted pension contributions from him, seemingly ignoring the fact that he is only 21 and would only join the pension scheme if he opted-in (which he has not done). We have managed to sort this out, but are concerned that this could happen again with other employees? Any ideas as to what has caused this and anything that we can do to prevent this happening again?
