AIS employers do not need to distribute hardcopies of the IR8A/IR8S/Appendix 8A/Appendix 8B to their employees as they submit the employment income to IRAS electronically.

Employees may refer to their payslips for details of their employment income and view their auto-included information via the 'Income, Deductions and Reliefs Statement' at myTax Portal when filing their individual income tax returns.
