This guide is general information for UK employers. It is not legal, tax, financial, investment or pension advice. Always check current official guidance and take advice appropriate to your circumstances.

An ongoing employer duty

Workplace-pension obligations are continuing. Employers monitor age and earnings, manage join and leave requests, maintain records, make contributions and consider re-enrolment every three years.

A client may appoint a provider to help administratively, but the employer remains legally responsible for completing applicable declaration and re-declaration duties correctly and on time.

What typically sits in the payroll process

Payroll-led administration can include support for assessing staff against automatic-enrolment criteria, calculating employee and employer contributions from approved payroll information, preparing provider files or schedules, and handling the payroll workflow around joiners, opt-ins, opt-outs, applicable refunds and contribution changes.

Axiom does not choose a scheme, act as a pension provider or trustee, or give regulated pension, financial, investment or tax advice.

Re-enrolment

Re-enrolment is a periodic employer duty. Employers must assess whether certain staff who are not active members of a qualifying pension scheme should be put back into a scheme. A related re-declaration is generally required. This generally occurs every three years.

Administrative support and reminders can be agreed in the service schedule. They do not remove the employer’s legal responsibility.
