To start a 501(c)(3) in Washington State, you incorporate a nonprofit corporation with the Washington Secretary of State, obtain a federal Employer Identification Number, adopt bylaws and a conflict of interest policy, then apply to the IRS for tax-exempt recognition using Form 1023 or Form 1023-EZ. Government filing fees total roughly $400 to $800, and the process runs from a few weeks to more than six months. Mark one deadline now: you have 27 months from the end of your incorporation month to file your IRS application if you want tax-exempt status backdated to your formation date.
File Articles of Incorporation With Washington
Incorporation is what brings the nonprofit into legal existence under Washington’s Nonprofit Corporation Act, RCW 24.03A. Before you file, pick a name that is distinguishable from any entity already on file with the Secretary of State and doesn’t imply a purpose different from what your Articles state. The Secretary of State’s online business entity search will confirm availability.
You also need a registered agent: a person or business with a physical Washington street address who accepts legal documents for the organization.1Washington State Legislature. RCW 24.03A.110 – Requirement of Registered Agent A director can serve in this role, or you can hire a commercial registered agent if you’d rather keep your home address out of public filings.2Washington Secretary of State. Registered Agents
What the Articles Must Contain
Washington law requires the following in your Articles of Incorporation:3Washington State Legislature. Chapter 24.03A RCW – Washington Nonprofit Corporation Act – Section 24.03A.100
- Corporate name meeting the distinguishability rule.
- Name and Washington address of the initial registered agent.
- A statement that the corporation is incorporated under RCW 24.03A.
- The purpose or purposes for which the organization is formed.
- A dissolution clause explaining how assets will be distributed if the organization closes.
- The number, names, and mailing addresses of the initial directors.
- A statement of whether the corporation will have members.
- Names, addresses, and signatures of each incorporator.
Two clauses need extra care because the IRS reviews them. Your purpose clause must limit activities to purposes recognized under Section 501(c)(3): charitable, educational, scientific, religious, or similar. Vague or broad purpose language is a common cause of delay at the federal stage. Your dissolution clause must direct any remaining assets to another qualified tax-exempt organization or a government entity. Without that language, the IRS won’t grant 501(c)(3) status.
How Many Directors You Need
Washington generally lets a nonprofit operate with as few as one director, but if you’re seeking public charity status under Section 509(a)(1) through (4) of the Internal Revenue Code, which covers most 501(c)(3) organizations, you need at least three.4Washington State Legislature. RCW 24.03A.505 – Number of Directors Directors do not need to be Washington residents.
Filing, Fees, and Speed
Submit the Articles through the Secretary of State’s online portal or by mail. Online filings often clear within a few business days; mail can take several weeks. Expedited processing costs an extra $100 per entity and is typically finished within three business days.5Washington Secretary of State. Filings, Forms and Information Check the Secretary of State’s website for the current base filing fee before you send payment; it has changed in recent years.
Get an EIN From the IRS
Once the state confirms incorporation, apply for an Employer Identification Number through the IRS website. The EIN functions like a Social Security number for the organization. You’ll need it to open a bank account, file the federal exemption application, and handle payroll. The IRS issues it immediately when you apply online, and there is no fee.
Adopt Bylaws and a Conflict of Interest Policy
Before applying for federal tax exemption, you need internal governance documents. The IRS reviews them as part of its evaluation, and weak governance slows approvals.
Bylaws function as the operating manual. They should cover the number of directors and how they’re elected, the schedule for regular meetings, what constitutes a quorum, voting procedures, officer positions and duties, and how the bylaws themselves can be amended. Keep them consistent with the Articles: if the Articles describe an educational mission, the bylaws shouldn’t lay out unrelated commercial operations.
Form 1023 asks directly whether your organization has a written conflict of interest policy. The policy should require directors and officers to disclose financial interests in transactions involving the organization, provide for recusal when conflicts arise, and require written records of how the board handled each conflict. That paper trail is your evidence that the organization operates for public benefit rather than for insiders.
Apply for Federal 501(c)(3) Status
This is the step that actually makes the organization a 501(c)(3). File either Form 1023 or Form 1023-EZ with the IRS through Pay.gov.
Which Form You File
Form 1023-EZ is available to organizations projecting annual gross receipts of $50,000 or less and holding total assets under $250,000. Complete the eligibility worksheet in the 1023-EZ instructions first; some organization types, including hospitals, schools, and supporting organizations, must file the full form regardless of size. If you don’t qualify for the streamlined form, the full Form 1023 requires detailed financial projections, narrative descriptions of planned activities, and compensation information for officers and directors.6Internal Revenue Service. Instructions for Form 1023-EZ (Rev. January 2025)
Fees and Processing Times
The user fee is $275 for Form 1023-EZ and $600 for the full Form 1023. Both are non-refundable and paid at submission through Pay.gov by card or bank transfer.7Internal Revenue Service. Form 1023 and 1023-EZ – Amount of User Fee The streamlined form often produces a determination letter within four to six weeks. The full Form 1023 can take six months or longer, especially if the reviewing agent requests more information. The determination letter is what confirms your status and your eligibility to accept tax-deductible donations.
The 27-Month Deadline
File the application within 27 months after the end of the month you incorporated, and the IRS will make your exempt status retroactive to your formation date. Miss that deadline, and exempt status starts only on the submission date.6Internal Revenue Service. Instructions for Form 1023-EZ (Rev. January 2025) Donations received before submission may not qualify as tax-deductible for donors in that scenario. If you’ve already crossed the 27-month mark and want retroactive status, your only path is the full Form 1023 with a request for an earlier effective date.
Public Charity or Private Foundation
Every 501(c)(3) is classified as either a public charity or a private foundation. Most founders want public charity status because private foundations face stricter rules on self-dealing, minimum annual distributions, and investment income taxes. The IRS measures public support over a five-year period; a public charity generally must receive at least one-third of its support from contributions from the general public.8Internal Revenue Service. Exempt Organizations Annual Reporting Requirements – Public Charity Support Test You’ll select your intended classification on the application, and new organizations get an initial five-year advance ruling period to build their public support base.
Handle Washington State Registrations
Washington has no state income tax, but nonprofits still have state filings to complete.
Business License
After incorporating, file a Business License Application with the Washington Department of Revenue. The processing fee is $50, non-refundable, for opening the first location of a new business. Select “Nonprofit Corporation” as the ownership structure. If you’ll have employees, register for industrial insurance (workers’ compensation) and unemployment insurance on the same application at no additional fee.9Washington Department of Revenue. Business License Application
Business and Occupation Tax
Washington’s Business and Occupation tax applies to nonprofits on gross revenues from regular business activities, the same way it applies to for-profits. Qualifying 501(c)(3) organizations can claim an exemption on fundraising income when that income furthers the organization’s goals and the event isn’t held at a regular business location.10Washington Department of Revenue. Nonprofit Organizations Revenue from ongoing commercial operations, such as a thrift store or café, remains taxable under B&O.
Property Tax Exemption
A nonprofit that owns or leases real property used for exempt purposes can apply for a property tax exemption under RCW 84.36. Initial applications are due to the Department of Revenue by March 31, with a 60-day window for property acquired mid-year, and the exemption requires an annual renewal declaration by the same March 31 date.11Washington State Legislature. Revised Code of Washington 84.36.815 – Tax Exempt Status, Initial Application, Renewal
Charitable Solicitations Registration
If your nonprofit will solicit donations from the public, Washington requires registration under the Charitable Solicitations Act (RCW 19.09) before you begin fundraising. This is separate from incorporation and the business license. Registration is mandatory unless the organization raises less than $50,000 annually using only unpaid volunteers, with no assets or income going to officers or directors outside the charitable class the organization serves. The initial registration fee is $60 and annual renewal is $40. Filings go through the Secretary of State’s Corporations and Charities Filing System. Organizations that fail to register after notice face a late filing fee, and the Secretary of State can assess civil penalties of up to $1,000 per violation.12Washington State Legislature. Chapter 19.09 RCW – Charitable Solicitations – Section 19.09.279
Stay on Top of Annual Filings
Once the 501(c)(3) is operational, ongoing filings at both the federal and state level keep it alive.
Every tax-exempt organization files an annual return with the IRS. Organizations with gross receipts normally $50,000 or less file Form 990-N, the electronic e-Postcard. Larger organizations file Form 990-EZ or the full Form 990 depending on revenue and total assets.13Internal Revenue Service. Annual Electronic Notice (Form 990-N) for Small Organizations FAQs – Who Must File Missing three consecutive years automatically revokes your tax-exempt status. There is no appeal. Reinstatement means filing a new application and paying the user fee again, and while status is revoked the organization cannot receive tax-deductible contributions.14Internal Revenue Service. Automatic Revocation of Exemption for Non-Filing – Frequently Asked Questions Small nonprofits get caught by this often, usually because founders assumed the e-Postcard wasn’t worth the trouble.
At the state level, Washington nonprofit corporations file an annual report with the Secretary of State to stay in good standing, submitted through the online system.5Washington Secretary of State. Filings, Forms and Information Letting the annual report lapse can lead to administrative dissolution of the corporation, a separate problem from federal revocation and one with its own fix. If you registered for charitable solicitations, that registration also renews annually. Between the federal return, state annual report, and charitable solicitations renewal, most Washington nonprofits track at least three recurring filings each year. Set the reminders now.
