LLC vs. S Corporation | Which is Right for My Business?

I'm frequently approached (virtually) by entrepreneurs that have great ideas for a new business to start. They know that they need to form SOME type of business, but often they don't know much more than the terms "LLC" or "Corporation." That's by no means a knock on them, as most people don't have much reason to know the differences between various types of business entities, much less how their structure can have an effect of operations, management, distributions, taxes and liability. Very commonly, for the types of businesses I work with, the choice boils down to two primary options: the LLC and the S Corporation. 

The question of which of those two entities is appropriate for a new business is one of great debate amongst lawyers and accountants. Simply put, there is no one-size-fits-all answer. While practitioners may have a preference for one form over the other (I have a theory that younger practitioners prefer the LLC being as it's a newer animal), when someone asks the question, "should I form an LLC or an S Corp?," it's impossible for me to provide a real answer and my response is always the same, "let's talk about it." \

I need to know the specifics of how you plan to operate your business, who is going to be involved, what roles they will play, what assets are going to be held, how operations are going to be funded, and where an entrepreneur sees his or her business in 5, 10 or 20 years, amongst a host of other things. 

Usually, the choice of entity is going to center on a few very specific operational objectives- objectives that, unsurprisingly, typically involve money, and how to avoid paying too much of it to the government. In that sense, I always encourage business owners to consult with their accounts. From a legal standpoint, we can make anything*** work, but often it's going to be easier when the accountant has steered the ship in the right direction. That said, there are some very high-level differences between LLCs and S Corporations which I've pulled together into a handy chart for those that may be curious. 

So, to those inquisitive entrepreneurs, I'd encourage you to read a bit about the differences, and then let's talk about it.
