What's Next After Filing

Once your Corporation is officially formed, you'll want to complete these important steps:

  • Draft Corporate BylawsCreate corporate bylaws that outline governance procedures, including board of directors' roles, officer responsibilities, meeting schedules, and voting procedures. While not filed with the state, bylaws are required under Idaho law and must be kept at the principal office.
  • Hold Organizational Meeting & Issue StockConduct an initial organizational meeting of the board of directors to adopt bylaws, elect officers, approve initial business decisions, and issue shares of stock to initial shareholders in accordance with your authorized share structure.
  • Obtain EIN and Fulfill Tax & License RequirementsApply for a federal Employer Identification Number (EIN) from the IRS, register with the Idaho State Tax Commission for applicable state taxes, and obtain any required local business licenses or permits before commencing operations.

Advantages

  • Limited liability protection shields shareholders' personal assets from corporate debts and legal judgments
  • Idaho has no franchise tax, reducing the ongoing tax burden compared to states like California or Delaware
  • Corporations can raise capital more easily by issuing multiple classes of stock and attracting investors or venture capital
  • Perpetual existence means the corporation continues regardless of changes in ownership or the death of shareholders
  • S-Corp election is available, allowing pass-through taxation and avoiding double taxation for qualifying corporations

Considerations

  • C-Corporations face potential double taxation — profits taxed at the corporate level and again when distributed as dividends to shareholders
  • More administrative complexity and formality required compared to LLCs, including mandatory bylaws, board meetings, and detailed record-keeping
  • Higher ongoing compliance burden with required annual reports, corporate minutes, and adherence to Idaho corporate statutes

Annual Obligations

Annual Report Fee:$0*
Report Due:Last day of the anniversary month of incorporation
* Idaho corporations must file an annual report with the Secretary of State by the last day of the month in which the corporation was originally incorporated. As of 2024-2025, there is no filing fee for the annual report. Idaho does not impose a separate state franchise tax on corporations, though corporations are subject to Idaho state income tax at a flat rate of 5.8% on net income. Failure to file the annual report can result in administrative dissolution.
