you cannot be an employee of a dis-regarded entity -- you are sole proprietor and report entity incomes and expenses on schedule-C
The only way to avoid this is to elect to be treated as a corporation. This election is made by filing Form 8832. Did you do so?
If your LLC is really a "disregarded" entity then you should not be taking a "salary" or "wages" from the LLC. The LLC is disregarded and all its income or loss, with any "wage" or "salary" not counted as an expense, is reported by you on your own Schedule C. If the "bottom line" of the Schedule C is positive (income) then that's your income and that's the starting point for calculating Self Employment tax.

What if he has two schedule C's. Is SET calculated on each one separately or on the net income from both?
