Each shareholder may at all proper times have access to the books of the company, to examine the same, and under such regulations as may be prescribed by the bylaws.
    Missouri Revised Statutes §351.215

    Your filed articles of incorporation are the first document for your corporate records. Your corporation will generate many other official records such as bylaws, meeting minutes, and your EIN.

    Office supplies intended for a corporation will help you stay organized and save time. Optionally, get a corporate record book, seal, and document templates.

    Draft bylaws (potentially using a template) which is the governing document for the corporation. The bylaws may contain any provisions for the regulation and management of the affairs of the corporation not inconsistent with law or the articles of incorporation (Missouri Revised Statutes §351.290). You will review and ratify the bylaws at your first board of directors meeting.

  7. Appoint Initial Directors

    The initial directors serve on the board until the annual meeting of shareholders (when directors are elected to the board). If the initial directors are not named in the articles of incorporation, they are appointed by the incorporator. The incorporator documents and signs this action for the corporate records.

  8. Hold Organizational Meeting

    Hold the organizational meeting of the incorporators or initial directors. Keep minutes of this meeting.

    As soon as convenient, an organization meeting of the first board of directors shall be held either within or without this state at the call of a majority of the directors, for the purpose of electing officers, accepting or rejecting subscriptions for shares, authorizing the issuance of shares, doing any other acts to perfect the organization of the corporation and transacting such other business as may come before the meeting.

  12. Consider Electing S-Corp Taxation

    By default, your corporation is taxed as a C-Corporation. Some corporations, especially smaller ones, benefit from electing S-Corp tax treatment:

    • C-Corps suffer from double taxation: the corporation pays taxes on profits then members pay taxes on their distributions. If profits exceed $250,000 per owner, you provide employee benefits, or you will re-invest most of your profit in the business, you may benefit from the low tax rates on retained earnings under C-Corp treatment.
    • S-Corp treatment avoids double-taxation. It is generally the best choice for small businesses. To accomplish this, file Form 2553: S-Corp Election with the IRS.
  13. Obtain Business Licenses & Permits

    To run your business legally, you must obtain applicable licenses and permits. The easiest way to navigate the wide range of federal, state, and local requirements is to search by your business type and locality using the Small Business Administration Business License & Permit look-up tool.
