According to the U.S. Census Bureau's Business Formation Statistics, Americans filed more than 5 million business applications in 2024, with LLC filings accounting for the majority of new formal business entities. The LLC structure is popular because it provides limited liability protection like a corporation while allowing pass-through taxation (profits flow to the owner's personal return via Schedule C, K-1, or 1040), avoiding the double taxation of C-corps, and it has become the default entity choice for most new small businesses. Idaho offers online filing through the Secretary of State, which typically processes faster than paper submissions. Standard processing in Idaho runs 5-7 business days, with expedited service available for an additional $40 reducing this to Same business day.

Most small business owners also spend $500–$2,000 in year one on general liability insurance, $50–$500 on business licenses and permits (varies by city and industry), and optionally $0–$500 on operating agreement templates or attorney review. Federal EIN applications are free through the IRS. If you plan to hire employees, add state unemployment tax registration and workers' compensation insurance.
