Final pay run for a pay group for a tax year is determined by details for the pay group in the Pay Calendars tab in Pay Setup > Pay Group. The UK tax year runs from 6 April to 5 April.
When the final pay for a legal entity has been committed, Dayforce updates the Final Pay status indicator in the Status column in Year End > UK Year End for a legal entity, as illustrated in the following screenshot:
If one or more final pay runs have not been committed, you can go to Payroll and load the pay runs in question to make sure that they are committed.
Once final pay has been committed, you can then ensure that the final ESP submission has been sent to HMRC before you proceed to the final step of publishing the P60 and P11D forms to send to employees.
