When should I run the Pensions Automatic Enrolment Assessment Process?

Run the process at the beginning of the pay period to assess employees and generate notification letters. Run it again at the end of the period, just before the full payroll cycle.

This gives employees a chance to opt out before a pension contribution is deducted in a payroll run, avoiding the need to process refunds. Also, it ensures that the final assessment takes into account any special payments or last-minute changes that may affect earnings.
