there are already a number of threads on this with a lot of interesting details, it may not hurt to search on "incorporating" in the search box. Generally, a lot of thoughts seem to center on that it is a nice idea, but for most people, it just makes it more complex and more expensive. And the new tax laws are imploding a lot of the value that an S Corp had for traders, but I do not happen to have the articles at hand that I read on this. Traders don't need the kind of liability protection afforded by LLC/corp Others may have more.
