How to assign Additional Superannuation Contribution (ASC) settings to employees

Created on  | Last modified on 


The steps in this article show you how to assign Additional Superannuation Contribution settings to your employees.


Additional Superannuation Contribution (ASC) calculations come into effect from 1 January 2019 and are only relevant for public sector employees. If you have employees that are liable for ASC deductions in 2019, you must assign the appropriate ASC settings within their records. 


  1. Open Sage Payroll and log into a payroll as normal.
  2. Do one of the following:
    • From the menu bar at the top of your window, click Processing then click Employee Details.
    • From the process map in the centre of Sage Payroll, click Edit Employees.
  3. Next to the Surname box, click browse   and click the relevant employee.
  4. Click the Deductions tab.
  5. Under Public Sector - Additional Superannuation Contribution (ASC), click the ASC Status arrow then click the relevant option.
  6. If the employee is in subsidiary employment and their main employment is elsewhere, select the Subsidiary check box.

    NOTE: If you select this check box, ASC calculates at the highest rate of the pension scheme the employee is a member of. The highest rate for a member of a standard or fast accrual pension scheme is 10.5%. For members of the single scheme, the highest rate is 7%.

  7. Click the Pension Scheme arrow, then click the relevant scheme the employee is a member of.
  8. Where an employee has provided an ASC45 from a previous employer, enter their YTD ASC details. Read More >
  9. Click Save.
  10. Repeat steps 3 to 8 for each employee that's liable for ASC deductions, then click Cancel.
  11. If you have more than one payroll, repeat the steps above in each of them if applicable.

You've now assigned ASC settings to your employee(s). In each subsequent pay period, when you process your employees' pay details, their ASC liability automatically calculates and appears on their payslip.

NOTE: ASC calculates before tax is deducted from an employee's pay. There is also employer PRSI relief in respect of ASC. Employee PRSI and universal social charge (USC) are deducted from an employee's pay after ASC calculates so there is no relief on these.
