How to Start a Nonprofit in Washington

Starting a nonprofit in Washington is remarkably straightforward, thanks to a clear statute and an efficient online filing system. The state offers a significant advantage: no state income tax. However, Washington's B&O (Business & Occupation) tax and property tax rules require attention. This guide walks you through formation, compliance, and the unique tax landscape.

Why Washington Is Good for Nonprofits

Washington has several built-in advantages:

• No state income tax: This is huge. You don't pay state income tax, and neither does your nonprofit. No state 990 filing required.
• Fast processing: 10–15 business days standard (expedited in 3 days for +$100).
• Clear statute: RCW 24.03A (effective January 1, 2022) is modern and well-organized.
• Email requirement: As of January 20, 2026, you must include email addresses in your filings, which is straightforward.

The main complexity is Washington's B&O tax and the property tax exemption process, which we'll detail below.

Formation Requirements: Step-by-Step

1. Check Name Availability and Understand Requirements

Your nonprofit name must be distinguishable upon Secretary of State records from all other registered business entities.

How to check:

• Use the Washington Secretary of State business entity search at sos.wa.gov
• Search is free and instant

Name requirements:

• Must be distinguishable (not identical or confusingly similar)
• Can include: club, league, association, services, committee, fund, society, foundation, guild, nonprofit corporation, nonprofit mutual corporation
• Cannot include: Inc., company, limited partnership, corporation, LTD, partnership, or abbreviations thereof

Optional name reservation:

• Reserve the name to hold it while you prepare your articles
• Exact process and fee not specified in current state resources

2. File Articles of Incorporation

This is your foundational legal document. Washington requires online filing (no paper option accepted).

Form: Articles of Incorporation – Nonprofit Corporation 24.03A Available at: https://sos.wa.gov/corporations-charities/business-entities/filings-forms-information Online filing instructions: https://sos.wa.gov/corporations-charities/business-entities/online-filing-instructions/start-domestic-wa-nonprofit-corporation-online

Required content:

• Name of the nonprofit corporation
• Registered agent name and address (Washington street address; cannot use P.O. box)
• Statement that corporation is incorporated under Washington law
• Purpose(s) for which corporation is organized (must meet federal charitable definition for tax exemption)
• Number of directors and their names/mailing addresses
• Statement of whether the corporation will have members
• Distribution of assets upon dissolution (must distribute to another 501(c)(3) or government entity for public purpose)
• Incorporator name and mailing address
• Signature of each incorporator

Critical for IRS 501(c)(3): Your Articles should include enhanced language:

• Clear charitable purpose clause
• Dissolution clause requiring assets to go to qualified charitable organizations upon dissolution
• Statement that organization is organized exclusively for exempt purposes

Filing methods:

• Online (fastest): Through Secretary of State website
• Mail (slower): To Secretary of State, Corporations Division

Fee:

• Standard: $80
• Reduced fee: $40 (if gross revenue in most recent fiscal year was less than $500,000 with voluntary certification)
• Expedited: +$100 (3 business day processing); mail expedite: +additional $100 with "EXPEDITE" label

Processing time:

• Standard: 10–15 business days
• Expedited: 3 business days

Important requirement: As of January 20, 2026, email address is required for Registered Agent and Principal Office fields. Filings without email will be rejected.

3. File Your Initial Report

Washington requires an Initial Report to be filed within 120 days of incorporation.

Good news: You can file the Initial Report together with your Articles of Incorporation at no additional fee. Otherwise, you'll file it separately within 120 days.

Due date: Last day of the month in which the corporation was originally formed (annually thereafter)

Failure to file: Results in administrative dissolution.

4. Obtain Your Federal EIN

How to apply:

• Online at IRS.gov (fastest)
• By phone: 1-800-829-4933

Timeline: Instant for online applications.

Cost: Free.

5. Prepare and Adopt Bylaws

Bylaws are your internal governance manual. Washington requires them but doesn't require filing with the state.

What bylaws should address:

• Board meeting procedures (frequency, notice, quorum)
• Officer responsibilities
• Director/officer duties and powers
• Member meetings (if applicable)
• Committee structure
• Conflict of interest policies
• Amendment procedures

Washington specificity: Washington provides default rules in RCW 24.03A if bylaws are silent on an issue, so bylaws can be flexible. However, it's best practice to address key governance items explicitly.

Important: Bylaws stay internal and confidential. Do not file with the state.

6. Hold Your Organizational Meeting

Gather your initial board (at least three directors for IRS purposes) and formally:

• Adopt bylaws
• Appoint officers
• Designate registered agent
• Document everything in written meeting minutes

These minutes are critical for your 501(c)(3) application.

7. Designate Your Registered Agent

Every Washington nonprofit must have a registered agent.

Requirements:

• Physical street address in Washington (no P.O. box)
• Individual or business entity authorized to do business in Washington
• Available during business hours to accept service of process

Commercial registered agent services: Available at typical cost of $50–$150/year.

Important: Email address is required for the registered agent (as of January 20, 2026).

8. Apply for Federal 501(c)(3) Tax-Exempt Status

Forms:

• Form 1023 (full application)
• Form 1023-EZ (simplified, if eligible)

Materials:

• Articles of Incorporation
• Bylaws
• Conflict of interest policy
• Financial projections
• Detailed program description

Processing: Typically 2–4 months.

Cost: Form 1023 is $275; Form 1023-EZ is $175. Fee waivers available for smaller organizations.

Governance Requirements

Board of Directors

• Private nonprofit minimum: 1 director
• Public benefit nonprofit minimum: 3 directors (recommended designation for stronger governance optics)
• IRS requirement: 3 directors for 501(c)(3) recognition
• Term limit: Maximum 5 years (unless corporation was formed before January 1, 2022 with longer-specified terms)

Officers

Required officers:

• President
• At least one Vice President (now optional under RCW 24.03A; previously required)
• Secretary
• Treasurer

Restrictions: Same person cannot hold both President and Secretary positions.

Other: Single person may hold multiple offices (except President/Secretary combination).

Note: Officers do not need to be board members.

Meetings

Washington law is permissive on meeting requirements. Specify in bylaws:

• Frequency (annual minimum is typical)
• Notice procedures
• Quorum (usually majority of board)
• Remote participation (permitted unless restricted by bylaws)
• Action without meeting (permitted by written consent)

Washington's Unique Tax Landscape

State Income Tax

Major advantage: Washington has no state income tax for individuals or corporations. This is a huge benefit for nonprofits.

What this means:

• No nonprofit state income tax exemption application needed
• No state Form 990 filing required
• This alone simplifies compliance significantly

Sales Tax

Washington's sales tax situation is more complex than in many states.

General rule: Washington does NOT provide a blanket sales tax exemption for nonprofit organizations.

Nonprofit purchases are generally taxed like any other consumer on items like:

• Office supplies and equipment
• Furniture
• Retail services

Fundraising exemption available:

• Sales tax is EXEMPT on fundraising activities IF:
  • Income is used to further your organization's charitable goals
  • Activity is not held at a regular business location
  • Activity is related to qualifying nonprofit purposes

If you conduct sales: Nonprofits that conduct regular retail sales must register and collect/remit sales tax, unless the sales qualify as exempt fundraising.

Business & Occupation (B&O) Tax

This is Washington's unique business tax that applies to all entities with gross receipts.

Applies to: All entities generating gross receipts/proceeds, including nonprofits, unless statutory exemption exists.

Registration requirement:

• Nonprofits with gross annual receipts under $12,000: Not required to register or pay B&O tax
• Nonprofits with gross annual receipts >$12,000: Must register with Department of Revenue

Tax rate: Varies by classification (rates not detailed in state resources reviewed).

Exemptions from B&O tax:

• Donations and grants (without goods/services provided beyond recognition)
• Proceeds from qualifying fundraising activities at non-business location
• Certain artistic/cultural organizations
• Adult family homes and comprehensive care centers

Key point: Despite having 501(c)(3) federal status, there's NO blanket Washington B&O tax exemption. You must navigate specific exemptions.

Deductions available:

• Fundraising deductions (for activities not at principal place of business)
• Charitable contribution deductions (bona fide donations without exchange of goods/services)

Property Tax Exemption

Property tax exemption is available but requires proactive application.

Eligibility:

• Must conduct activity specifically identified in RCW Chapter 84.36, including:
  • Private nonprofit schools, colleges, universities
  • Churches and religious places of worship
  • Benevolent, protective, rehabilitative social services
  • Camp facilities for organized recreational activities

Property use requirement:

• Organization must own and exclusively use property for exempt activity

Application timeline:

• Initial application: Must file within 60 days of purchase or conversion to exempt use
• Filing period: Annually between January 1 and March 31
• Annual renewal: Required every year
• Changes: Must report any changes in use or ownership within 60 days

Contact: Washington Department of Revenue, Property Tax Division, 360-534-1400

Annual Compliance and Ongoing Filings

Content:

• Registered agent information (name and address)

Federal Form 990 Filing

Requirement varies by organization size:

• Form 990-EZ: Gross receipts under $200,000 AND total assets under $500,000
• Form 990: Gross receipts over $200,000 AND total assets over $500,000

Deadline: 15th day of 5th month after fiscal year end (May 15 for calendar-year organizations)

Critical: Three consecutive years of non-filing results in automatic revocation of 501(c)(3) tax-exempt status.

Charitable Solicitation Registration

Required if:

• You receive $50,000+ in contributions annually, OR
• You receive any amount WITH:
  • Paid employees
  • Commercial fundraiser involvement
  • Paid persons carrying out organization activities

Exemptions (no registration required):

• Raising under $50,000 with ALL activities/fundraising by unpaid volunteers
• Churches (as defined by IRS)
• Political organizations
• Fundraising for specific individuals (if all proceeds go to that individual)

Initial registration:

• Fee: $60
• Timeline: Register before you begin soliciting
• Regulatory agency: Washington Secretary of State, Nonprofits-Charities Division

Annual renewal:

• Fee: $40
• Deadline: Within 11 months after fiscal year close
• Late fee: $50 if renewal missed

Renewal reminders: Secretary of State sends email/postcard approximately 60 days before expiration.

Public Benefit Nonprofit Designation (Optional)

Washington allows an optional "Public Benefit Nonprofit" designation under RCW 24.03A.245.

Benefits:

• Enhanced governance credibility
• Stronger public trust implications
• IRS recommendation for better charitable status recognition

Requirements:

• Minimum 3 directors (vs. 1 for private nonprofit)
• Current IRS 501(c)(3) recognition OR exempt from applying under IRC § 508(c)

Temporary designation available: If you've applied to IRS for 501(c)(3) status, you can request temporary Public Benefit designation (valid up to one year, renewable).

Key Compliance Deadlines

| When | What | Fee | Notes | |------|------|-----|-------| | Within 120 days of incorporation | Initial Report | $0 (if filed with Articles) | Can file separately for additional fee | | Last day of anniversary month (ongoing) | Annual Report | $10 | Mandatory; failure results in administrative dissolution | | Before first solicitation | Charitable Solicitation Registration (if required) | $60 | Required if $50K+ or if using paid staff | | Within 11 months of fiscal year close | Charitable Solicitation Renewal (if registered) | $40 | Late fee $50 if missed | | 15th of 5th month after fiscal year end | Form 990/990-N (federal) | $0 | Three consecutive years of non-filing = loss of status | | January 1 – March 31 (annually) | Property Tax Exemption Application (if claiming) | $0 | Renewal required annually |

Important Considerations

No State Income Tax Is a Major Win

This eliminates significant compliance burden. Take advantage of it.

B&O Tax Requires Attention

Because there's no blanket nonprofit B&O exemption, you must carefully monitor your gross receipts. Once you exceed $12,000, you must register. Plan ahead and understand which of your activities (if any) qualify for exemptions.

Sales Tax Exemption Is Limited

Don't assume your nonprofit gets a sales tax exemption. The fundraising exemption is helpful, but regular activities are taxable. If you conduct sales, register to collect sales tax.

Property Tax Exemption Is Not Automatic

Unlike some states, you must affirmatively apply. And you must renew annually between January 1 and March 31. This is a local process, so contact your county assessor.

Email Required in All Filings

As of January 20, 2026, all filings must include email addresses for registered agent and principal office. Filings without email will be rejected.

Board Size Determines Governance Level

Public benefit nonprofits (3+ directors) have stronger governance optics. Private nonprofits (1 director) are legally permitted but less ideal for 501(c)(3) credibility. Plan for 3+ from the start.

Your Next Steps

1. Check name availability in the Secretary of State database.
2. Identify your initial board (at least 3 unrelated directors for 501(c)(3) purposes).
3. Prepare Articles of Incorporation with enhanced IRS language and email addresses.
4. File online for fastest processing (10–15 business days).
5. File Initial Report (can be combined with Articles at no extra fee).
6. Obtain your EIN from the IRS.
7. Draft bylaws covering governance, meetings, and officer roles.
8. Hold organizational meeting and document in minutes.
9. Apply for 501(c)(3) status (Form 1023 or 1023-EZ).
10. Register for charitable solicitation if you'll fundraise (if applicable).
11. Mark your calendar for annual report deadline (anniversary month).
