Why is the warning message: "The tax reference number is mandatory" displayed on an employee's Edit Payslip screen?

The warning message "The Tax reference number is mandatory"  will display underneath the payslip information tab on an employee's payslip.

      Navigate > Employee > Payroll Processing > Edit Payslip > Payslip Information

      

The warning message will appear based on the following scenarios:
  1. If the YTD value on tax code 4102 is greater than 0.00.
  2. The employee is linked to the tax status "Independent Contractor (No Tax)" and the YTD value on tax code 4102+4115 is 0.00.
  3. The employee is linked to the tax status "Resident NED (No PAYE)" and the YTD value on tax code 4102+4115 is 0.00.
  4. The employee is linked to the tax status "Foreign Employment" and the YTD value on tax code 4102+4115 is 0.00.
  5. If the YTD value on tax code 4102+4115 is 0.00 and the YTD value for tax codes 4116+4120 is greater than 0.00.
  6. If the YTD value on tax code 4102+4115 is 0.00 and the checkbox, "Par 11A(5) Fourth Schedule notification - no PAYE" on the tax profile screen is activated.
  7. If the employee is linked to the "Labour Broker" tax status & the YTD value on tax code 4102 is greater than 0.00, then the warning message will state: "The tax reference number is mandatory.".
Note! This is only a warning message and not a run error. You will still be able to close runs and continue with payroll processing before adding a tax reference number. The employee's tax reference number can be updated on the Tax Profile screen.
