1. Not entirely correct. In most states, S Corporations pay more taxes on their income than do LLCs. Also, you don't avoid paying the self-employment tax; you just pay it in a different way, as payroll and other taxes through the S Corporation. In many states, taxes incidental to the employee relationship will end up exceeding the self-employment tax. Moreover, wages paid through an S Corporation cannot be characterized as capital gain (15% rate vs. higher), whereas income earned from an LLC can be capital gain. Also, the S Corporation has significant restrictions. The most important is that only US citizens/legal residents can be investors. If any of the restrictions is not met, the S Corporation will be taxed as a C Corporation, resulting in double taxation of income. 2. I agree; the only benefit of a series LLC is avoiding the administrative costs of forming multiple LLCs. Unfortunately, the accounting costs and hassles for a series LLC will more than swallow up the (relatively small) administrative savings. Also, the series LLC is not a new form; it's just an extension of the sub-partnership concept and will be taxed the same way. (If the corporate tax structure is selected, it each new LLC in the series will be treated as a subsidiary.) If you're worried about filing taxes, just choose the simplest form. The tax code is very simple as long as you don't try to play games with it.
