When Montana wins

Hidden costs of forming in Delaware from outside
If you live and operate in Montana but form in Delaware, you almost always pay both states' annual fees because you must register as a foreign LLC in Montana. The advertised cost difference often disappears entirely once foreign qualification fees and dual registered agents are factored in.
Decision framework
- Operating in Montana? Form in Montana.
- Pure holding company or non-resident? Delaware wins for VC-backed or holding structures.
- Raising VC money? Delaware C-Corp is the standard. Montana won't be accepted by most institutional investors.
