Perry, I have to somewhat disagree with you. Business organization is very critical relative to tax advantages and it absolutely can help shield personal assets from business liability if done...correctly. The recent tax laws have really hurt "sole proprietorship" when it comes to taxes. All many of us are saying is to get qualified advise from a small business professional up-front to insure that there is clear understanding of what each organizational scenario brings to the table for both taxation and for liability mitigation.
I will agree with you that some accountants will push for more complex arrangement than may be necessary, but that's a risk with any professional resource. They are in business, too. The same thing happens in your own profession as well as many others. Nature of the beast...and "buyer beware"...
