The Employment ID is a requirement for RPNs and payroll submissions and is used in conjunction with the employer registration number and the employee's to identify to Revenue where an employee:

• Has multiple roles within your company in the same tax year.
• Had previously left and then rejoined your company in the same tax year.

Sage Payroll automatically allocates each employee with a default Employment ID value of 1 within the Employee Details window.

While not recommended, you can change the default Employment ID value for all employees if you want to. You can enter a value using any combination of the following:

• Upper and lower case letters.
• Digits 0 to 9

Based on Revenue's guidelines, you should only change the employment ID for an employee, if one or both of the following scenarios apply:

• The employee left and rejoined your company in the same tax year.
• The employee has multiple employments (roles) within your company.
