FORM KWSP 17A(AHL) KHAS - For Individual Employee
If you are an individual employee, mostly you will need to fill up the first form, Form KWSP 17A(AHL)-Khas. If your company decided to submit the details of a group of employee under the same form, then your Human Resources @ Admin Department will arrange for Form KWSP 17AA(AHL)-Khas. For KWSP 17A(AHL)-Khas (individual), employee just need to fill in Part B & C only. The rest, it's your Human Resources @ Admin Deparment or your employer's responsibility.
Hope this help!
