Verdict: Colorado is one of the cheapest and most DIY-friendly states to form a nonprofit — roughly $335 to $685 in total fees, most forms submittable in under an hour online.
What works: Low filing fees ($50 for Articles of Incorporation, free EIN), same-day online processing for most filings, and a 27-month IRS window that lets you fundraise before your 501(c)(3) arrives.
What doesn't: The IRS wait for a full Form 1023 can stretch 7 to 9+ months, and the charitable solicitation step (often missed) can expose you to fines if you skip it.
Ideal for: First-time Colorado nonprofit founders who want to do the filings themselves without paying a $300+ filing service.
Worth considering if: Your nonprofit will have complex governance, multi-state operations, or you are unsure whether your activities qualify under 501(c)(3) — in those cases, a one-time attorney consult is worth it.
You have an idea you can't shake. A cause that won't let go. And one thought that keeps stopping you cold: I can't do anything until everything is legit.
Here's the truth most guides skip: starting a Colorado nonprofit is not a sprint to a 501(c)(3) determination letter. It is a 2-to-6-month formation runway, and the real risk is not the paperwork. It is the months you spend feeling stuck while waiting on the IRS. Colorado's filing fees are blissfully cheap (around $50 for Articles of Incorporation, free EIN), and you can legally start fundraising the day Colorado approves your Articles. The IRS gives you a 27-month window after state registration to file Form 1023, so the long federal wait does not have to bury your momentum.
This guide walks you through all 13 steps a first-time Colorado founder needs, in order, with the real fees, the real timelines, and the charitable solicitation step most other guides skip entirely. You do not need a $3,000 lawyer retainer. You do not need a $300 filing service. You can submit most of these forms yourself at sos.state.co.us in under an hour each.

For a small nonprofit: Colorado is one of the cheaper states to form in, and the steps are DIY-friendly. The hard part is not the filings. It is the patience to keep building momentum during the IRS wait. This guide is built so you can do the whole thing yourself, without paying a filing service for forms you can submit in 30 minutes.
Step 1: Define your mission and purpose
Before any paperwork, get clear on what your nonprofit will actually do. A strong mission statement is not just inspiration. It is required language for your Articles of Incorporation and your federal tax exemption application.
Work through these questions with a notebook:
- What specific problem will your nonprofit solve in Colorado?
- Who exactly will you serve, and where?
- What programs or activities will you run in your first year?
- Is another Colorado nonprofit already doing this well? (If yes, consider volunteering or partnering with them instead.)
- What needs are going unmet that other organizations are not addressing?
Write your mission in one or two sentences a stranger could understand. You will reuse this language in your Articles of Incorporation, your bylaws, your IRS application, your website, and every grant proposal you ever write.
For a small nonprofit: Resist the urge to make the mission broad enough to "cover everything." A narrow, specific mission ("provide trauma-informed yoga to Denver-area youth aging out of foster care") wins grants and donors faster than a wide one ("support youth wellness in Colorado").
Step 2: Choose and reserve your nonprofit name
Your name is both a marketing choice and a legal filing. In Colorado, your nonprofit name must be distinguishable from every other entity already on file with the Secretary of State. Unlike some states, Colorado does NOT require nonprofits to include words like "corporation," "incorporated," or "company" in the name. You can include those terms if you want, but they are optional under CRS 7-90-601.
Run your name through the Colorado Secretary of State business name search before you fall in love with it. If the name is available and you are not ready to file your Articles yet, you can reserve it:
- Reservation fee: $25 online
- How long the reservation lasts: 120 days
- Renewable: Yes, for another 120 days, with another $25
Reservation is optional. If you plan to file your Articles within a week or two, skip it.
For a small nonprofit: Pick a name you can also get as a .org domain and as social handles. The name is free to choose. The rebrand later is not.
Step 3: Recruit your board of directors
Colorado's Revised Nonprofit Corporation Act (CRS 7-122) requires a minimum of one director, not three. Your Articles or bylaws can set a higher number, and most nonprofits do. The IRS expects a working board, and Form 1023 reviewers look closely at whether you have independent directors.
Practical guidance:
- Aim for at least 3 directors. This is the IRS sweet spot and matches the officer roles (president, secretary, treasurer) Colorado expects.
- One person can hold more than one officer position in Colorado.
- Directors must be 18 or older.
- Recruit for complementary skills: legal, financial, marketing, and community connections to the population you serve.
- Directors have fiduciary duties under Colorado law (duty of care, duty of loyalty, duty of obedience). Make sure every director understands what they are signing up for.
You also need an Incorporator, the person who signs and submits your Articles of Incorporation. The Incorporator can be a director, but does not have to be.
For a small nonprofit: A founding board of 3 to 5 people who actually show up beats a board of 10 names on a letterhead. Recruit for engagement, not for the resume.
Step 4: Appoint a registered agent
A registered agent is the person or company that accepts legal documents on behalf of your nonprofit. Colorado requires every nonprofit to keep one on file with the Secretary of State.
Requirements:
- Must have a physical street address in Colorado (a PO box does not count)
- Must be available during regular business hours to receive service of process
- Can be an individual (including you, if you have a Colorado address) or a commercial registered agent service
If you serve as your own registered agent, the cost is $0. Paid commercial registered agent services are available if you prefer privacy or do not have a Colorado address. Pricing varies, so shop around before committing.
If your nonprofit ever loses its registered agent and does not replace them, Colorado can administratively dissolve your nonprofit. Keep this information current.
For a small nonprofit: If you have a stable Colorado address and you are comfortable with the public-record exposure, be your own registered agent. You can switch to a commercial service later if your situation changes.
Step 5: File your Articles of Incorporation
This is the filing that legally creates your Colorado nonprofit. You file directly with the Colorado Secretary of State, online. You do NOT need to pay a filing service $300 or more to submit this form. The form is short, the system is plain-English, and most founders finish it in 30 to 45 minutes.
- Processing time: typically same-day for online filings
Information you will need ready:
- Your nonprofit's exact legal name
- Your registered agent's name and Colorado street address
- Incorporator name and address
- A purpose statement (your mission, written in legal-ready language)
- The required 501(c)(3) provisions: a purpose limitation (the nonprofit is organized exclusively for charitable, religious, educational, scientific, or similar purposes) and a dissolution clause (on dissolution, remaining assets pass to another 501(c)(3) or to a government entity for public purpose)
The IRS-required purpose and dissolution language is the most-missed item on first-time filings. If your Articles do not include these provisions, the IRS will reject your 501(c)(3) application later. Use the Colorado Secretary of State's help file as you complete the form, and double-check the purpose and dissolution provisions before submitting.
For a small nonprofit: File this yourself. There is no honest reason to pay a filing service for a 30-minute form. The $250 to $400 you would have spent on a service is better used on your first donor receipt printing, your first event venue, or kept in the bank for the 501(c)(3) application fee.
Step 6: Get your EIN from the IRS
An Employer Identification Number (EIN) is your nonprofit's federal tax ID. You need it before you can open a bank account, apply for 501(c)(3) status, or hire anyone.
- How long: immediate. You get your EIN at the end of the online session.
- Limit: only one EIN application per "responsible party" per day
Print or save the EIN confirmation (CP 575) the IRS issues. You will need it for your bank, your state tax registration, and your 501(c)(3) application.
For a small nonprofit: Apply for the EIN the same week you file Articles. There is no reason to wait, and your next step (opening a bank account) depends on it.
Step 7: Hold your first board meeting and adopt bylaws
Bylaws are your nonprofit's internal rulebook. They are not filed with Colorado, but they are required for your 501(c)(3) application and they govern how your organization actually runs.
Your Colorado nonprofit bylaws should include:
- Number of directors and how they are elected, terms, and removal
- Officer roles (president, secretary, treasurer at minimum) and duties
- How board meetings are called, noticed, and held (in-person, by phone, by video)
- Quorum requirements and voting rules
- A conflict of interest policy (IRS expects this)
- Membership provisions, if you will have members
- Indemnification language for directors and officers
At your first board meeting, adopt the bylaws, elect officers, approve opening a bank account, authorize filing the 501(c)(3) application, and approve the conflict of interest policy. Record minutes. Sign and store them with your corporate records. The IRS will want to see organized minutes during your 1023 review.
For a small nonprofit: Use a Colorado-specific nonprofit bylaws template from the Colorado Nonprofit Association or a similar source as your starting point. Do not write bylaws from scratch, and do not copy from a for-profit corporation. The structure is different.
Step 8: Apply for federal 501(c)(3) tax-exempt status
This is the big one. Federal 501(c)(3) status is what makes donations to your nonprofit tax-deductible and what most grantmakers and corporate giving programs require before they will fund you.
You have two options:
|
| Form 1023-EZ | Smaller orgs that pass the Eligibility Worksheet (generally under $50,000 in projected annual gross receipts and under $250,000 in assets) | $275 | 2 to 4 weeks |
| Form 1023 (full) | Larger orgs, or any org that fails the Eligibility Worksheet | $600 | Up to about 191 days for 80% of determinations per the IRS, with current real-world waits often 7 to 9+ months |
Form 1023-EZ has a required Eligibility Worksheet in its instructions. A single disqualifying "yes" means you must file the full Form 1023 instead. Do the worksheet honestly. Misrepresenting eligibility can cost you your determination letter later.
The reframe most founders need: you do NOT have to wait on the IRS to start fundraising. The IRS gives you a 27-month window after your state registration date to file Form 1023, and once Colorado approves your Articles and you complete your charitable solicitation registration (Step 11), you can legally solicit donations in Colorado. While your 1023 is processing, you can build a donor base, run launch events, and accumulate operating funds. See our 501(c)(3) application guide for a deeper walkthrough.
For a small nonprofit: If you qualify for 1023-EZ, take it. The fee is less than half, the form is much shorter, and the timeline is dramatically faster. Just verify your eligibility honestly. If you fail the worksheet, file the full 1023 and use the wait time to fundraise.
Step 9: Register for Colorado state taxes (only if you need to)
Not every Colorado nonprofit needs a state tax account right away. You need to register with the Colorado Department of Revenue if you:
- Will have employees and need to withhold state income tax
- Will collect Colorado sales tax (for example, on retail merchandise sales)
- Will have any other Colorado tax-collection obligation
Register through MyBizColorado when one of these applies. If you are an all-volunteer nonprofit with no employees and no taxable sales, you can skip this step for now and revisit when your activities change.
For a small nonprofit: If you are a board of volunteers with no payroll and no merchandise sales, you very likely do not need this yet. Do not register for taxes you do not owe.
Step 10: Apply for Colorado sales tax exemption
Once you have your federal 501(c)(3) determination letter, you can apply for Colorado sales tax exemption. This lets your nonprofit make tax-exempt purchases for items used directly in your charitable activities.
How it works:
- You apply with the Colorado Department of Revenue. Confirm the current application form and instructions on their website before filing.
- The exemption applies to purchases used in your charitable activities, not to purchases for unrelated commercial activities.
- You will receive a certificate of exemption to present to vendors.
You generally cannot apply until your federal 501(c)(3) letter is in hand, so this step waits for Step 8 to complete.
For a small nonprofit: If most of your spending is on services (rent, payroll, professional fees) and not taxable goods, the exemption saves less than founders expect. Worth doing, but do not stress about it before you have the IRS letter.
Step 11: Register for charitable solicitation
This is the step most other Colorado guides skip, and skipping it can get your nonprofit fined.
Under the Colorado Charitable Solicitations Act, charitable organizations must register with the Secretary of State before engaging in any solicitation campaigns in Colorado. "Solicitation" is broad: it includes donation requests on your website, fundraising events, grant applications, direct mail, and online giving forms.
Key details to confirm on the Colorado SOS Charities FAQ before you file:
- Initial registration fee: confirm the current fee at sos.state.co.us before filing (the published rate has been as low as $8 and commonly cited as $10 — verify the live figure)
- Annual renewal: confirm current renewal fee at sos.state.co.us
- Amendment fee: confirm current amendment fee at sos.state.co.us
- Where: Colorado Secretary of State charity registration portal
- Exemption: Some small organizations under $25,000 in gross revenue may qualify for an exemption. Verify your status on the SOS Charities FAQ before deciding to skip registration.
This step matters because it is the legal switch that lets you start fundraising. Once your Articles are approved (Step 5) and your charitable solicitation registration is on file, you can solicit donations in Colorado, even if your 501(c)(3) determination has not arrived yet.
For a small nonprofit: Do this step right after your Articles are approved. The registration fee is small and it is the cheapest insurance policy in nonprofit law — it unlocks legal fundraising on day one.
Step 12: Start fundraising without losing money to fees
Here is the math after all the formation work above: you just spent about $335 to $685 forming your Colorado nonprofit. You are state-registered. You can legally solicit donations. The IRS clock is ticking and you have up to 27 months to file Form 1023, so you can fundraise the whole time.
The last thing a brand-new Colorado nonprofit needs is a fundraising platform that takes 5% to 8% of every donation in platform and processing fees. That is real money: $50 to $80 out of every $1,000 raised, gone before it reaches your mission.
Zeffy is a free online donation platform built for nonprofits. 100K+ nonprofits use Zeffy to raise money with one-time and recurring donation forms, free event ticketing for launch events and community fundraisers, a free raffle tool (note that Colorado requires a separate raffle license through the Secretary of State before you run a raffle, so handle that filing first), and automatic tax receipts for every donor. No platform fee, no transaction fee, no credit card fee. Ever. Zeffy is funded by optional contributions from donors, so 100% of every donation reaches your nonprofit.
Zeffy only requires that you be recognized as a nonprofit at any level, including state-level recognition. You do NOT need your IRS determination letter to sign up. That means the moment Colorado approves your Articles and your charitable solicitation registration is on file, you can be live and accepting donations.
The math after formation:
- $335 to $685 to form your Colorado nonprofit (one-time)
- $0/month to fundraise, forever
How Get Grounded Foundation raised over $500,000 fee-free
The Get Grounded Foundation is a Colorado nonprofit that supports youth mental health awareness, funding mental health support for children. Their programs include mobile food pantry support, trauma-informed yoga, mental health support by and for LGBTQ+ youth, art therapy, and dog and equine-assisted therapy. Keeping these programs running depends on donor contributions, so Get Grounded needed a simple, mobile-friendly donation experience where supporters could give as little or as much as they wanted, receive automatic receipts, and know their full gift reached the mission, not a payment processor.
That is when Get Grounded found Zeffy.
Since partnering with Zeffy in 2023, Get Grounded has launched four donation campaigns, from the Sam Aden Kindness Fund to Sam's Day of Stoke. Across these campaigns, Get Grounded has raised over $500,000 for its programs without paying a single processing fee. They built donation forms in a few clicks and could promise donors that 100% of every contribution went straight to the cause.
Step 13: Stay compliant year after year
Forming the nonprofit is the easy part. Staying in good standing year after year is what keeps your 501(c)(3) status alive and your reputation clean with donors, grantmakers, and Colorado regulators.
Your annual compliance checklist:
- Colorado Periodic Report: due annually, in your nonprofit's anniversary month of formation. Filing fee is $25 per year. Late filings can lead to delinquent status and eventually administrative dissolution. Your registered agent is responsible for ensuring this gets filed.
- Federal annual return (Form 990 series):
- Form 990-N (e-Postcard): for nonprofits with gross receipts normally under $50,000
- Form 990-EZ: roughly $50,000 to under $200,000 in gross receipts and under $500,000 in assets
- Form 990 (full): $200,000 or more in gross receipts or $500,000 or more in assets
Failing to file any 990 series return for three consecutive years results in automatic revocation of your federal 501(c)(3) status. Put this on the calendar.
- Charitable solicitation renewal: confirm the current annual renewal fee at sos.state.co.us; due annually with the Colorado Secretary of State.
- Maintain your registered agent: update the Secretary of State immediately if your agent's address or status changes.
- Keep corporate records: board meeting minutes, signed bylaws, conflict of interest disclosures, financial records, and donor records. The IRS expects these to exist and be organized if they audit you.
Donor records are part of corporate records hygiene the IRS expects. Keep clean donor data from day one, not after your first audit notice. You can track your first donors in a free CRM with tags, donor history, and automatic receipts, so your records grow with you instead of becoming a year-three cleanup project.
For a small nonprofit: Build a one-page annual compliance calendar with three dates: Periodic Report month, 990 deadline (5 months and 15 days after the close of your fiscal year), and charitable solicitation renewal date. Put it on the wall. You will save yourself a panicked December.
How much does it cost to start a nonprofit in Colorado?
Here is the all-in itemized cost for forming a Colorado nonprofit, assuming you DIY the filings:
|
| Name reservation | $25 | Optional |
| Articles of Incorporation | $50 online | Required |
| EIN | Free | Required |
| 501(c)(3) application (Form 1023-EZ) | $275 | Required (choose one) |
| 501(c)(3) application (Form 1023 full) | $600 | Required (choose one) |
| Charitable solicitation registration | Confirm current fee at sos.state.co.us | Required (before soliciting) |
| Colorado sales tax exemption | Free | Optional, but recommended |
| Total (1023-EZ path) | ~$335 plus registration fee (confirm at sos.state.co.us) | |
| Total (full 1023 path) | ~$660 plus registration fee (confirm at sos.state.co.us) | |
Colorado is on the affordable end for nonprofit formation. Compared to states that charge $100 to $250 just for the equivalent of Articles of Incorporation, Colorado's $50 online filing is a gift. For more on stretching every dollar at the start, see our guide to nonprofit startup costs.
For a small nonprofit: The $300+ gap between 1023-EZ and full 1023 is the single biggest variable. Spend an hour with the IRS Eligibility Worksheet before you commit. If you qualify for 1023-EZ, take it.
How long does it take to start a Colorado nonprofit?
Realistic timelines, in order:
- Mission and board recruitment: 2 to 6 weeks
- Articles of Incorporation: usually same-day approval online
- Bylaws and first board meeting: 1 to 2 weeks
- Charitable solicitation registration: same day to a few weeks
- Federal 501(c)(3): 2 to 4 weeks for 1023-EZ, up to 191 days (about 6.4 months) for 80% of full Form 1023 determinations per IRS data, with practitioner-reported real-world waits often 7 to 9+ months
- Colorado sales tax exemption: a few weeks after your IRS letter arrives
Total realistic timeline: 2 to 6 months for most founders. Longer if you file the full 1023 in a slow IRS queue.
Three tips to compress the timeline:
- 1. File Articles of Incorporation, charitable solicitation registration, and the EIN application in the same week. They do not need to wait on each other.
- 2. Have your bylaws drafted before your first board meeting. Use the meeting to adopt them, not to write them.
- 3. Start the 501(c)(3) application as soon as your bylaws are adopted. Do not let it sit on a board member's desk for two months.
And the big reframe: the IRS gives you a 27-month window after state registration to file Form 1023, and Colorado lets you legally fundraise as soon as your Articles are approved and your charitable solicitation registration is on file. Your timeline to fundraising can be as short as 2 to 4 weeks. The timeline to your IRS letter is separate, and you do not have to wait on it.
For a small nonprofit: Plan for 2 to 6 months end-to-end, but plan to be raising money inside the first month. The waiting is real. The helplessness is optional.
FAQs - Starting a nonprofit in Colorado
Do I need a lawyer to start a nonprofit in Colorado?
No. Colorado's Secretary of State system is designed for DIY filings, and most founders can complete every step in this guide themselves. A lawyer is worth the money in two situations: your nonprofit will have complex governance (membership structure, multi-state operations, employee leasing) or you are unsure whether your activities qualify under 501(c)(3). For the standard small Colorado nonprofit, a lawyer is optional, not required.
How many board members do I actually need?
Colorado law (CRS 7-122) requires a minimum of one director. Practically, aim for at least 3 unrelated directors. The IRS looks for independent governance during Form 1023 review, and 3 is the smallest number that lets you fill the standard officer roles (president, secretary, treasurer) without one person wearing all the hats.
Can I pay myself as a nonprofit founder?
Yes, with limits. Founders can be paid as employees (salary or wages), reimbursed for legitimate expenses, or paid as contractors for specific services. Compensation must be reasonable for the work performed and approved by an independent board. Excessive compensation can trigger IRS intermediate sanctions and threaten your 501(c)(3) status.
What is the difference between a nonprofit and a 501(c)(3)?
"Nonprofit" is a Colorado state-level designation. You become a Colorado nonprofit corporation the moment your Articles of Incorporation are approved. "501(c)(3)" is a federal IRS tax classification that makes donations to your organization tax-deductible. You can be a Colorado nonprofit without being a 501(c)(3), but most funders and grantmakers require the federal 501(c)(3) status before they will give.
Do I need to register before fundraising in Colorado?
Yes. Colorado's Charitable Solicitations Act requires charitable organizations to register with the Secretary of State before any solicitation activity in the state. Some small organizations under $25,000 in gross revenue may qualify for an exemption. Check the Colorado SOS Charities FAQ before deciding to skip registration.
Can I start fundraising before my 501(c)(3) is approved?
Yes. Once Colorado approves your Articles of Incorporation and your charitable solicitation registration is on file, you can legally fundraise in Colorado. The IRS gives you a 27-month window after state registration to file Form 1023, so your fundraising can begin months before your federal determination letter arrives. Be transparent with donors that 501(c)(3) status is pending if their deductibility matters to them.
How do I start a nonprofit with little money?
The total Colorado state and federal fees are largely unavoidable, but everything else can be near-free. Use volunteers instead of paid staff. Ask for in-kind donations of office space, equipment, and professional services. Apply for early-stage grants. Run your fundraising on a free platform so platform fees do not eat into your runway. See our guide to starting a nonprofit with no money for the full playbook. And for the bigger picture across all states, our parent guide on how to start a nonprofit covers the federal steps in depth.
