Often at the year end you will need to match up payroll records from your accounting system with records from your payroll system.
Here is how to get that information:
Go to Reports, Ledger Reports, Nominal Activity Report (v2)
Set the desired Date Range
Set the Nominal to Payroll
Save as Excel
Repeat for Nominal Employee Payroll
If you have separated out Employer PRSI or Director Payroll, repeat the process for each of these.
