I don't understand your confusion.

I have CIMB and there is option to transfer to EPF. It's pretty straighforward.
If you're talking about automatic deduction, isn't that done by your employee, not from your own CIMB account?

i just transfer whenever I want from my CIMB account, and it just shows up as self contribution on EPF statement.

>and I cant find any option to change the limit, it stated max rm5000.
Well, I'm not that rich but have you tried breaking it into multiple transactions over time?

>Is that 60k additional savings into epf will earn dividends as usual?
I'm trying not to sound snarky, but the answer is a pretty obvious yes.
