Information you will need to file the Washington Articles of Incorporation
To become a nonprofit corporation in Washington you must file the Articles of Incorporation for a Washington Nonprofit Corporation.
Here are the sections that you will need to complete.
Section 1: UBI Number
At this stage, most organizations will not have a UBI (Unified Business Identifier) number. You can select "NO" and one will be assigned to you.
In the rare case that your nonprofit has already filed with another Washington state agency and has received a UBI, then you can include that here.
Section 2: Name of Corporation
Enter the name you have selected.
For help with selecting a name for your nonprofit read our comprehensive guide on how to name a Washington nonprofit.
Section 3: Purpose
Describe the purpose of your nonprofit organization and additional provisions.
In order to qualify for 501(c)(3) status, the organization’s purpose must explicitly be limited to one or more of the following:
- Charitable
- Religious
- Scientific
- Literary
- Testing for public safety
- Fostering national/international amateur sports competition
- Preventing cruelty to animals/children
NOTE: You can read the IRS guidelines to learn more.
Section 4: Period of Duration
Most organizations are not started with an end date in mind. If this is the case for your nonprofit, select “This Corporation will have perpetual duration.”
If your organization is planning to be in existence for a fixed amount of time put the end date or the number of years it will be in existence.
Section 5: Registered Agent & Registered Office
Read this lengthy section carefully and only fill out the sections that pertain to your organization. You’ll need to include the agent’s name, street address, and consent.
The registered agent can be any entity registered to do business in Washington or any person who is a resident of the state.
Enter the information of the registered agent you have selected.
For more information read our guide: What is a registered agent? and The Washington Registered Agent Guide.
Section 6: Effective Date
This section allows you to determine the date on which your nonprofit corporation officially forms:
Option A: Your organization will officially form on the day the Secretary of State files your Articles of Incorporation
Option B: You select the date of formation (it can be any day up to 90 days after filing)
Section 7: Initial Board of Directors
At least 3 unrelated directors will need to be named.
When filling the form do not use any prefixes such as “Mr.” or “Ms.” and only use the suffix box for titles of lineage such as ‘Jr.’, ‘Sr.’, or ‘III’ but not for designations such as M.D. or Ph.D.
Since this document will become public record you may want to use a post office box address rather than the residential addresses of the directors to maintain privacy.
Enter the information of the directors selected.
Section 8: Incorporator Information
The incorporator is the person who completes, signs, and submits the certification of formation. This person does not need to be a part of your organization. This can be you or a lawyer helping you with the process of formation.
Section 9: Distribution of Assets
Use this section of the articles of incorporation to formally state what the assets of the organization will be used for, and what will happen to the assets if the organization is dissolved.
To be eligible for 501(c)(3) status, you must convince the IRS that the organization’s assets will always only be used for the purposes approved under 501(c)(3) rules. To this end, you must include provisions ensuring that in the event your organization is dissolved, the assets of the organization will be used towards tax-exempt purposes.
Section 5 of this sample document provides an example of these provisions required for 501(c)(3) eligibility.
Section 10: Return Address
In this section, you may provide a mailing address and email for an additional contact person for your filing. If you don’t want this information to become public record, leave this section blank.
