EP rejected and need help to understand the rejection reason.

I will try to answer your questions as follows:
1. Obviously, they think it is too high.
2. Clearly, they are asking for proof that the company can pay your salary. Whether that is the only issue? See below.
3. This is a standard phrase. The part "For renewals, ..." does not apply to you.

At last, the company that lodged the EP application is owned by me (100%).

Here we have the real issue: The intended visa type for this situation is the EntrePass, not EP!
While the "EP in one's own company" loophole has still not been entirely closed, it has become more and more difficult in recent years to achieve this. Unless yours is a business Singapore covets (which seems unlikely, given the reply you received) they will apply similar criteria on your EP as on an EntrePass.
I recommend you engage a reputed business incorporation service provider (not the cheapo types who claim they can also do this!) to help you assess the chances and develop a strategy. Or you hire a local professional manager instead of moving here yourself (That is what MoM actually wants!).

my ep also rejected as same as alezander12.

hi beppi.
my case is different i use to work in singapore and my salary was 8000 and now my employer applý for me not my own company.mom want to proof of my employer can pay this salary or not.i have 7 years experience in singapore.this is not my own company .i use to get 8000 salary when i was in singapore.how can solve it and how can convince mom i will get 8000 when i work in singapore in this new company

First you write your situation is the same, now it is different again!
If MoM doubts that the employer can and will pay the offered salary, it‘s their responsibility to convince them otherwise (e.g. by showing what financial benefit you will bring to them).

can you help me what my employer have to show mom.what is good.please advice me.

what is good thing to show mom.how convince mom they will salary 8000 to me.as i told you my ex company paid me 8000 when i was in singapore.

The employer should submit the information and documents MoM requests - they should show that they can and will pay the offered salary and that the benefits of hiring you at that price outweigh the cost.

Unaudited financial statements showing cash inflows to pay salaries and other operating costs is what needs to be provided to MoM as supporting documents.

hi.did you appeal.have you got any good answer.
