Idaho is inexpensive if you file online: the LLC formation filing is $100 online or $120 on paper, and the annual report can be filed online at no charge. The trap is treating free maintenance as no maintenance; the LLC still needs a registered agent, annual report, seller's permit or employer accounts when required, and local or industry licensing checks.

Important considerations
- The initial filing fee is only one part of the cost. Annual reports, franchise taxes, registered-agent service, licenses, and local requirements may also apply.
- Tax registration depends on the business activity, location, employees, and tax programs that apply.
- Forming in Idaho does not automatically eliminate registration requirements in the state where the business actually operates.
