  • 2 per page (high resolution)
  • 2 per page (low resolution)
  • Irish Language Payslip

Highlight the employee name and click Print Employee History

Can wages be processed in advance when the payroll administrator is going on annual leave?

Yes, you can process wages in advance when going on annual leave.   Always use the Revenue Payroll Notification (RPN) available at the time the payment is processed.

You must ensure you send the Payroll Submission Request (PSR) to Revenue in advance also.


A mistake has been made on the payroll how can this be corrected?

Corrections must always be dealt with on the basis of 'follow the money'.

This means that if an employee has been underpaid/overpaid in a previous pay period, the correction of the underpayment/overpayment should be made in the next payroll run you perform.

Where an employee, however, has physically received a payment amount which differs to the amount shown in the payroll, this will require a 'correction submission' to be made to Revenue in order to rectify the error.

To perform this type of correction:

  • Select 'Corrections' on the menu bar, then choose 'Payment was different'
  • Select the period number you wish to make the correction for
  • Choose the employee for whom you wish to make a correction for from the drop down menu
  • On the left hand side, the selected employee's original payment amount and the associated deductions will be displayed on screen
  • On the right hand side, enter the employee's correct gross pay or net pay accordingly. 
    • If entering a net figure, click 'Calculate Net to Gross'
    • If entering a gross figure, click 'Calculate Gross to Net'
  • The software will calculate and display the applicable deductions
  • To proceed, select 'Apply Correction'
  • A Correction PSR will now be prepared by the software. If you have no more corrections to make, simply close out of the Corrections utility and access Process Icon No. 6 to submit the correction PSR to Revenue.

My new company is on the wrong period number, how can this be changed?

If your employer file is on an incorrect start period number this can be changed prior to processing payroll. 

To change the start period go to Utilities > Set start period for mid year setup > enter the correct period number > 'OK', the period number will now be amended.


The ROS Digital Certificate was renewed but I am getting 'error 1016' in the payroll now?

An employee is in receipt of Illness Benefit, how do I process this?

Illness Benefit is subject to PAYE only, it is not subject to USC or PRSI.

Since 1st January 2018, employers are no longer required to tax Illness Benefit through the payroll.

Since this date, Revenue will adjust the employee's tax credits and cut off points via the Revenue Payroll Notification (RPN). Revenue will receive real-time interfaces of taxable Illness Benefit from the Department of Employment Affairs and Social Protection (DEASP).

As a result of this change, there will be more frequent RPNs for employees. While employers are no longer responsible for taxing Illness Benefit through the payroll, it is extremely important to retrieve RPNs before processing payroll each pay period.

In addition, since 1st January 2018, Illness Benefit letters are no longer be delivered to the ROS Inbox.

Prior to 1st January 2018, employers were responsible for collecting PAYE due on Illness Benefit issued to employees.
