Earned income

If I have LLC and put my earned income in LLC account, with an tax ID (not my SS #), can any one know that is my income?

Answer

What do you mean by "anyone"?

The IRS will know, because your SSN (or someone else's associated with your LLC) was used to apply for your LLC's EIN.

Can casual creditors know? Probably not, particularly if you used an outside service as your registered agent and not your own home or business address.

Persistent creditors can find out by subpoenaing you to a judgment debtor examination and other legal processes.
