If you’re interested in learning about this, be aware that S-corp and C-corp are widely used misnomers. A corporation is a corporation (and an LLC is not) but they all can be taxed under sub chapters C, S, K, and others based on the specific details of the entity.
C corporation is just a shorthand way of saying “privately incorporated voluntary association taxed under sub c (probably with dreams of being a public company someday, otherwise they’d be sub s).
Not trying to “but acktchually” you, just suggesting that your next stop after reading about corporations is probably the tax code. (Enjoy that).
extra bonus -- actual attorneys who are familiar with those codes learn not to discuss it at all .. for whatever reasons.. it really is valuable information, as in scarcity
turns out, i actually meant benefit corporation. (i've heard people refer to them as b-corporations, but didn't realize there was another thing called b-corporation)
