How to File

1

Choose a Corporate Name

Select a unique name that includes a required designator such as 'Corporation,' 'Incorporated,' 'Company,' or an abbreviation like 'Corp.' or 'Inc.' Search the Oregon Secretary of State business name database to confirm availability before filing.

30 minutes

2

Appoint a Registered Agent

Designate a registered agent with a physical street address in Oregon (P.O. boxes are not allowed) who is available during normal business hours to receive legal and official documents on behalf of the corporation. The agent can be an individual Oregon resident or a registered commercial agent.

15 minutes

3

File Articles of Incorporation

Prepare and file the Articles of Incorporation with the Oregon Secretary of State Corporation Division, either online through the Oregon Business Registry or by mail. The filing must include the corporate name, registered agent information, number of authorized shares, and incorporator details.

1-2 hours

4

Draft Corporate Bylaws

Create corporate bylaws that govern the internal operations of the corporation, including shareholder rights, board of directors structure, officer roles, meeting procedures, and voting requirements. Although not filed with the state, bylaws are legally required in Oregon and must be maintained at the principal office.

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 MeetingConvene the initial organizational meeting of the board of directors to adopt bylaws, appoint officers, authorize issuance of stock, and address other initial business matters. Document the meeting with formal minutes and retain them in the corporate records book.
  • Obtain EIN and File IRS Form 2553Apply for a federal Employer Identification Number (EIN) from the IRS at no cost, then file IRS Form 2553 (Election by a Small Business Corporation) to elect S-Corporation tax status. The form must be filed no later than two months and 15 days after the beginning of the tax year the election is to take effect, and all shareholders must consent in writing.
  • Register for Oregon State Taxes and Obtain LicensesRegister with the Oregon Department of Revenue for applicable state taxes, including corporate income tax (Oregon recognizes the federal S-Corp election), payroll taxes, and any applicable sales or use taxes. Obtain any required local business licenses or permits specific to your industry and municipality.

Advantages

  • Pass-through taxation avoids federal and Oregon double taxation — income is taxed only at the shareholder level, not at the corporate level
  • Shareholders who are employees can receive a reasonable salary and take additional distributions, potentially reducing self-employment (FICA) taxes compared to a sole proprietorship or partnership
  • Provides strong personal liability protection, shielding shareholders' personal assets from business debts and legal judgments
  • Oregon recognizes the federal S-Corp election automatically, simplifying state tax compliance without requiring a separate state election filing

Considerations

  • Strict IRS eligibility restrictions apply — S-Corps are limited to 100 shareholders, only one class of stock, and shareholders must be U.S. citizens or resident aliens, excluding many investors and corporate shareholders
  • Oregon S-Corporations are still subject to the Oregon corporate excise tax with a minimum tax of $150, and shareholders must pay Oregon personal income tax on their pro-rata share of income regardless of distributions received
  • More administrative burden than an LLC, including requirements to hold and document annual shareholder and director meetings, maintain detailed corporate minutes, and adhere to formal corporate governance rules under Oregon Revised Statutes Chapter 60

Annual Obligations

Annual Report Fee:$100
Report Due:Anniversary of formation month
Oregon S-Corporations must file an Annual Report with the Secretary of State each year, due by the anniversary month of the corporation's formation, with a $100 filing fee. Oregon does not impose a separate franchise tax. S-Corporations in Oregon file Form OR-20-S (Oregon S Corporation Tax Return) and pay an excise tax at the entity level at a minimum of $150, while income passes through to shareholders who report it on their individual Oregon Form OR-40 returns. Shareholders who are Oregon residents must pay Oregon personal income tax on their pro-rata share of S-Corp income.
