To display voluntary and other tax components on a pay advice:
Go to Payroll, Reports, Pre-Process Pays, Pay Advices. If a historical pay, go to Payroll, Reports, History, Re-print Pay Advices.
From the Options tab, Options box, tick Show Tax Breakdown.
Print the pay advice as usual. The tax details should now show on the pay advice.
This can also be selected when printing pay advices from the Payroll Process Pays Workflow.
