How to File

1

Choose a Corporate Name

Select a unique name for your S-Corporation that includes a required designator such as 'Incorporated,' 'Corporation,' 'Company,' or an abbreviation (Inc., Corp., Co.). Conduct a name availability search through the Oklahoma Secretary of State's online business name database to ensure the name is not already in use.

2

Appoint a Registered Agent

Designate a registered agent with a physical street address in Oklahoma (P.O. boxes are not acceptable) who is authorized to receive legal documents and official state correspondence on behalf of the corporation. The registered agent can be an individual Oklahoma resident or a commercial registered agent service authorized to do business in Oklahoma.

1-2 hours

3

File Articles of Incorporation

Prepare and file the Articles of Incorporation (Form 0101) with the Oklahoma Secretary of State. The document must include the corporate name, registered agent information, number of authorized shares, names and addresses of incorporators, and the purpose of the corporation. File online, by mail, or in person with the $50 minimum filing fee.

1-2 hours

4

Draft Corporate Bylaws

Create corporate bylaws that outline the internal rules and procedures governing your corporation, including shareholder meetings, voting procedures, officer roles, and board of directors responsibilities. While not required to be filed with the state, bylaws are legally required to be maintained internally and are essential for corporate governance.

2-4 hours

What's Next After Filing

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

  • Hold Organizational Meeting and Issue StockConduct an initial organizational meeting of the board of directors to adopt bylaws, appoint officers, and authorize the issuance of stock. Issue stock certificates to shareholders, maintaining records of all stock transactions. S-Corporations may have no more than 100 shareholders and only one class of stock.
  • Obtain EIN and File IRS Form 2553Apply for a federal Employer Identification Number (EIN) from the IRS at no cost via the IRS website. Then file IRS Form 2553 (Election by a Small Business Corporation) to elect S-Corporation tax status. This form must be filed no later than 2 months and 15 days after the beginning of the tax year for which the election is to take effect, or at any time during the preceding tax year.
  • Register for Oklahoma State Taxes and Obtain Business LicensesRegister with the Oklahoma Tax Commission for applicable state taxes, including withholding tax if you have employees, and sales tax if applicable to your business. Obtain any required local business licenses or permits specific to your industry and municipality. File the Oklahoma Annual Certificate each year to maintain good standing.

Advantages

  • Pass-through taxation avoids federal corporate double taxation, with income and losses reported on individual shareholders' personal tax returns.
  • Shareholders who are active employees can reduce self-employment tax liability by splitting income between reasonable salary and distributions.
  • Oklahoma S-Corporation shareholders enjoy limited personal liability protection, shielding personal assets from business debts and legal judgments.
  • S-Corporation status lends credibility and a more formal business structure, which can be attractive to investors, lenders, and potential business partners in Oklahoma.

Considerations

  • Strict IRS eligibility requirements limit S-Corporations to 100 shareholders, one class of stock, and prohibit non-resident alien shareholders, limiting growth and investment flexibility.
  • Oklahoma S-Corporations must comply with ongoing corporate formalities such as annual meetings, minutes, and record-keeping, which require more administrative effort than LLCs.
  • Oklahoma franchise tax applies to S-Corporations with a minimum annual tax of $250, adding an ongoing cost that pass-through entities like LLCs may also face but is structured differently.

Annual Obligations

Franchise Tax:$1.25
Annual Report Fee:$25
Report Due:July 1
Oklahoma S-Corporations must file an Annual Certificate with the Secretary of State by July 1 each year with a $25 filing fee. The Oklahoma franchise tax is assessed at $1.25 per $1,000 of capital invested or used in Oklahoma, with a minimum of $250 and a maximum of $20,000. S-Corporations in Oklahoma are subject to Oklahoma's franchise tax filed with the Oklahoma Tax Commission using Form 200. Shareholders must also pay Oklahoma state income tax on their proportionate share of corporate income on their individual returns.
