It also maintains the most up-to-date and advanced case law that corporate lawyers in Delaware can rely on, which decreases liability and litigation between Delaware corporations and LLCs.

Incomparable tax savings are also available to Delaware companies. Delaware corporations doing business outside of Delaware are exempt from state income taxes.
