LLC Questions

[Levar Wilson]

I have a few questions as it relates to LLCs and I am sure that they have been answered countless times here on the forum so I apologize in advance. I do not know what I do not know, so anytime I mention what "I know" I am really making a semi-informed assumption (smiles). I know that salaries and profits of an LLC are taxed according to the self-employment category. Is this still at 13%? I read through some open source articles and the phrase "unless the LLC opts to be taxed as a corporation" surfaced which I immediately thought, "Why would an LLC want to be taxed as a corporation?" Is it true that only salaries (not profits) are taxed for corporations? If this is correct, and since I will be the sole proprietor of the LLC with technically no salary, this should be the route I pursue, correct? What is the maximum amount of operating losses that can be deducted from regular income for an LLC? Does commingling exist in an LLC with a sole proprietor? I really appreciate each of you taking the time and answering my rookie questions. Thank you.
