Step 1: Define Your Mission and Name
Write a clear mission statement that describes who you serve and what problem you solve. Search the Secretary of State business name database to confirm your name is available.
Step 2: Recruit Your Board of Directors
Missouri requires a minimum of 3 directors. The IRS expects at least 3 unrelated board members for a 501(c)(3) application. Best practice is 5-15 members with diverse skills. See our Board of Directors guide.
Step 3: File Articles of Incorporation
File your articles with the Secretary of State.
- Fee: $25 (expedited: add $25)
- Filing: Online filing available
- Processing time: 3-5 business days
Your articles must include:
- Purpose clause referencing Section 501(c)(3) of the Internal Revenue Code
- Dissolution clause directing assets to another 501(c)(3) organization
- Name and address of registered agent in Missouri
Without these clauses, the IRS will reject your application. See our Articles of Incorporation guide.
Step 4: Adopt Bylaws and Governance Policies
At your organizational board meeting, adopt bylaws covering board structure, officer roles, meeting procedures, and amendments. Also adopt a conflict of interest policy and compensation policy — the IRS asks about both on Form 1023.
Step 5: Get Your EIN
Apply for an Employer Identification Number at irs.gov/ein. Free and instant. See our EIN guide.
Step 6: File IRS Form 1023 or 1023-EZ
- Form 1023-EZ: $275, 2-4 week approval, for organizations under $50,000/year in projected receipts
- Full Form 1023: $600, 3-6 month approval, for larger organizations
File within 27 months of incorporation for retroactive tax-exempt status. Use our Form 1023 Checklist to prepare.
Step 7: Register for Charitable Solicitation
Missouri requires charitable solicitation registration with the Attorney General. The registration fee is $15. You must register before soliciting donations from the public.
Renew annually. Failure to register before fundraising can result in penalties.
Step 8: Apply for State Tax Exemption
Federal 501(c)(3) status does not automatically exempt you from Missouri state taxes. Apply through the Department of Revenue for state income tax and sales tax exemptions. You will need your IRS determination letter.
Step 9: Set Up Operations
With legal formation complete, set up your systems:
- Open a bank account with your EIN and articles
- Set up fund accounting — purpose-built for restricted funds and Form 990 reporting
- Configure your donor CRM for gift tracking and tax receipts
- Create a donation page to accept online gifts
- Set up volunteer management if your programs need volunteers
For a complete timeline, see our Setting Up a Nonprofit guide.
Step 10: Ongoing Compliance
Missouri has minimal annual reporting requirements for nonprofits.
Also mark your Form 990 deadline — missing three consecutive years means automatic revocation of your tax-exempt status.
