Chapter S election (which an LLC can do, by the way, it's not a particular type of entity) does pass through taxing, and has a thing where the "profit distribution" of the corp, after paying shareholders "a reasonable salary", can be distributed without self-employment taxes, just regular income taxes. So you can save some 15% on some portion of your income--if you have an income larger than whatever you may be able to justify to the IRS as a reasonable salary. Other options may make sense based on how much money is kept in the company, if you have passive investors, how much money you're making, how much work the shareholders do, etc.
