Washington Corporation Requirements

After forming a corporation, you must undertake certain steps on an ongoing basis to keep your business in compliance. These steps are also important in preserving the limited liability a corporation provides its owners. This guide outlines the ongoing requirements for Washington corporations.

Corporate records

Washington corporations must keep the following items with their corporate records at the principal office:

  • The Articles of Incorporation and any amendments
  • Bylaws
  • Financial statements for the past three years
  • Minutes of shareholder meetings for the past three years
  • Records of actions taken by the shareholders without a meeting for the past three years
  • Written communications to shareholders for the past three years
  • A list of names and business addresses of current directors and officers
  • The corporation’s initial report and the most recent annual report

Corporate taxes and fees

The following are taxation requirements and ongoing fees for Washington corporations:

  • Annual report. Washington requires corporations to file an annual report on or before the last day of the anniversary month of the company’s incorporation. The cost is $69.
  • Taxes. For complete details on state taxes for Washington corporations, visit Business Owner's Toolkit or the State of Washington.
  • Federal tax identification number (EIN). An EIN is required for corporations that will have employees. Additionally, most banks require an EIN in order to open a business bank account.
  • State tax identification number. Washington requires a state tax identification number.

Business licenses

Business licenses and/or permits are required for most businesses. The BizFilings Business License Application Package can help you stay on top of these requirements.

S corporation election

Washington does not recognize the federal S corporation election and does not require a state-level S corporation election. You can still have an S corporation in Washington. The S corporation will only be an S corporation for federal tax purposes and not for state tax purposes. For state purposes, the corporation will be treated as a regular C corporation.
