Four of us would like to form an LLC. Can we all be subcontractors under the LLC and, if so, what would the pros and cons of this be?

In Kansas, forming an LLC does not determine whether or not one is a subcontractor. Whether or not one is a subcontractor is relevant in master/servant relationships, not in corporate formation. So there are really two issues here: 1) Whether, for tax and contract purposes, you are considered  subcontractors; and 2) What contractual format do you want your LLC to take? It sounds as if you are in fact wanting to form a partnership under the aegis of the LLC format. I handle many such corporate matters. If you want to discuss this in more detail, feel free to email me.

Not entirely sure what you mean by "subcontractors under the LLC"? Essentially, since you are setting it up, you may all be more-or-less anything you like under it:

1) You may all be members; and more specifically, you may all be managing members (have authority and a management role.)

2) You may all be employees (draw a salary and, if appropriate, benefits).

3) You may all be contracted by the LLC to perform work for it as independent contractors (on a 1099) basis, as long as when you set it up, you don't bar (in it's organizing documents) contracting with members.

Hope this answers your question.
