A flagged payslip is one that did not pass validation against the worker's Certificate of Sponsorship (CoS). Only flagged payslips can be resolved. Valid, pending and unable-to-validate payslips do not show resolution options. Owners and editors can resolve a flag; viewers can see the history but cannot make changes. For a short walkthrough of the flow, see What's new: resolving a flagged payslip in Halo.
First, work out why it was flagged
The reason is shown on the payslip. It will usually be one of: the annualised salary is below the CoS requirement, the weekly hours are below the CoS hours, or the total across the rolling window is short.
Two ways to resolve a flag
Route one: the figure was read incorrectly. If we misread gross pay, hours, or the pay period, correct the figure and the payslip is re-checked against the CoS straight away. If the corrected figure now meets the requirement, the flag clears. If it still falls short, the payslip stays flagged and you can record a reason instead.
Route two: the figure is correct, but there is a legitimate reason it is lower. Here you record the reason rather than editing anything. Reasons include statutory sick pay, maternity or paternity pay, an agreed temporary reduction, unpaid leave, a shortfall you have already back-paid, or other with a short explanation. You set the period the reason covers, confirm the reduction is temporary and that the contracted role and underlying salary are unchanged, and accept a short declaration.
Resolving a flag is not the same as reporting a change
Clearing a flag in Borderless keeps your compliance score accurate, but if the underlying reduction needs reporting to the Home Office, that is a separate step you control. See Reporting a Change of Circumstance for when a reduced or unpaid pay period must be reported.
