Start Up Business Structure Choices
I taught a class this morning on entrepreneurship legal issues at the Duquesne University SBDC's GATE program where the appropriate legal structure for starting a small business was a topic for discussion.
This article from the SBA (in pdf format),Selecting the Legal Structure for your Business is a good summary of the applicable considerations in choosing whether to operate as a Sole Proprietorship, Partnership, C-Corporation, S-Corporation or Limited Liability Company (LLC).
More infomation about the federal tax consequences of each option is available from the IRS here and here.
