How to File

1

Choose a Corporate Name

Select a unique name that includes 'Corporation,' 'Incorporated,' 'Company,' or an abbreviation (Corp., Inc., Co.). Conduct a name availability search on the Oklahoma Secretary of State website to confirm the name is not already in use.

30 minutes

2

Appoint a Registered Agent

Designate a registered agent with a physical street address in Oklahoma who is available during normal business hours to receive legal documents and official notices on behalf of the corporation. The agent can be an individual Oklahoma resident or a registered agent service.

1-2 hours

3

File Articles of Incorporation

Prepare and file the Articles of Incorporation (Form 0101) with the Oklahoma Secretary of State, providing the corporate name, registered agent information, number of authorized shares, and incorporator details. File online at sos.ok.gov or by mail with the applicable filing fee.

1-2 hours

4

Appoint Directors and Hold Organizational Meeting

Appoint the initial board of directors and hold an organizational meeting to adopt bylaws, elect officers, authorize issuance of stock, and handle other preliminary corporate matters. Document all decisions with meeting minutes.

2-4 hours

What's Next After Filing

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

  • Draft and Adopt Corporate BylawsCreate corporate bylaws that outline the internal governance rules, including director and officer roles, meeting procedures, voting rights, and stock issuance policies. While not filed with the state, bylaws are legally required and should be kept in the corporate records book.
  • Obtain EIN and Open a Bank AccountApply for a Federal Employer Identification Number (EIN) from the IRS at no cost, which is required for tax filings, hiring employees, and opening a business bank account. Use the EIN to open a dedicated corporate bank account to maintain separation of personal and business finances.
  • Register for Oklahoma State Taxes and LicensesRegister with the Oklahoma Tax Commission for applicable state taxes, including corporate income tax and sales tax if selling taxable goods or services. Obtain any required local business licenses or permits specific to your industry and municipality.

Advantages

  • Limited liability protection shields shareholders' personal assets from corporate debts and legal judgments
  • Easier to raise capital by issuing multiple classes of stock and attracting outside investors or venture capital
  • Perpetual existence means the corporation continues regardless of ownership changes or shareholder death
  • Potential tax advantages including deductible employee benefits and eligibility for S-Corp election to avoid double taxation
  • Enhanced credibility with customers, vendors, and lenders due to formal corporate structure

Considerations

  • Double taxation risk for C-Corporations, where profits are taxed at the corporate level and again as shareholder dividends
  • More administrative burden than an LLC, including required board meetings, meeting minutes, bylaws, and strict record-keeping
  • Higher formation and ongoing compliance costs, including franchise taxes and potential legal and accounting fees
  • Less management flexibility compared to an LLC, as governance must follow statutory corporate formalities

Annual Obligations

Franchise Tax:$1.25
Annual Report Fee:$0*
Report Due:July 1
* Oklahoma corporations must file an Annual Certificate with the Secretary of State by July 1 each year. The franchise tax is calculated at $1.25 per $1,000 of capital employed in Oklahoma, with a minimum of $250 due to the Oklahoma Tax Commission. Corporations must also file an Oklahoma Corporate Income Tax Return (Form 512) annually. Failure to file the Annual Certificate can result in administrative dissolution.
