What is the best resource for running a 1 person C corporation? (I'd like to know the rules / regulations / prevent myself from doing things that cause silly mistakes or are blatantly illegal). [I suspect that even if I own 100% of the company, there are still certain regulations.]
nolo.com has some books on that sort of subject. Since they have a lot of them, the best thing to do is go to your library, look through a bunch, and see which one is best for you, and then consider buying it.
A C corporation, involving one person, probably doesn't make sense. You probably want a S corp or LLC. In any case, a lawyer is good but I've always gotten my advice from my accountant. The lawyer knows the rules. The accountant knows how the rules affect your money.
But an LLC is more flexible and generally simpler to start.
If you're looking to build a small profitable company, I'd go LLC. If you're looking for VC money today, go C-Corp. If you're looking to build a profitable company but want VC money in a few years, consider an S-Corp.
