The best value you’ll get from IncFile for LLC service is their Silver package for free (plus state fee). With this option, you’ll receive a year of registered agent service along with your LLC formation, and of course, it’s always difficult to complain about that price point!
If you have some extra room in your budget, you could also go with the Gold package for $149, which adds an EIN and an operating agreement, both of which most companies need. This package also includes a company alerts system.
