No. The Basic Plan Document will, typically, state that regardless of the selection made between W-2, Withholding, and 415 Safe Harbor, the compensation for a 'self-employed' individual is 'earned income from self-employment'.
Okay, now you're like... Huh???.... The key here is that when you have an owner of a business that is not incorporated, and he is therefore not receiving a W-2, then his income is determined from the profits of the business (i.e. K-1, Net Schedule C).
Good Luck!
