How to Start a 501(c)(3) Tax-Exempt Nonprofit: A Step-by-Step Guide for US Founders

Countsure step-by-step guide on how to start a 501(c)(3) tax-exempt nonprofit — two professionals reviewing formation documents representing IRS nonprofit incorporation and tax-exemption application process for US founders

A 501(c)(3) isn’t something you simply register for in one step. You first incorporate your organization as a nonprofit at the state level, draft your formation documents with the right exempt-purpose and asset-dissolution language, obtain an EIN, and then apply to the IRS for tax-exempt recognition using Form 1023 or the streamlined Form 1023-EZ. Once the IRS approves you, you secure exemptions at the state and local level and keep up with annual filings to hold onto the status

Key Takeaways

  • Incorporating a nonprofit and becoming tax-exempt are two separate steps – forming the entity does not make it tax-exempt.
  • Tax-exempt status under section 501(c)(3) is granted by the IRS, not the state, after you file Form 1023 or Form 1023-EZ.
  • File within 27 months of formation to have your exemption apply retroactively to your incorporation date.
  • Smaller organizations – generally those with $250,000 or less in assets and $50,000 or less in annual gross receipts – may qualify for the simpler Form 1023-EZ. 
  • Missing your annual IRS filing for three years in a row results in automatic loss of exempt status.

What “501(c)(3)” Actually Means (and What It Doesn’t)

A 501(c)(3) organization is a nonprofit that the IRS has formally recognized as exempt from federal income tax under section 501(c)(3) of the Internal Revenue Code. These entities exist to serve a public benefit rather than to generate profit for owners or shareholders – and that public-benefit purpose is exactly what earns them their special tax treatment.

To qualify, your organization’s purpose has to fall within one of the categories the IRS recognizes: religious, educational, charitable, scientific, literary, public-safety testing, fostering amateur sports competition, or preventing cruelty to children or animals. Most 501(c)(3)s land in one of two buckets – public charities, which draw broad support from the public, and private foundations, which are usually funded by a single source such as a family or company.

The biggest misconception: many founders assume that once they’ve incorporated a nonprofit, they’re automatically tax-exempt. They aren’t. Incorporating only creates the legal entity in your state. Tax exemption is a separate application you make to the IRS. If your work also touches US business incorporation services or multi-state operations, getting this distinction right early saves expensive amendments later.

Before You File: The Foundation That Decides Everything

Your path to exemption is largely won or lost in the formation documents. Like a for-profit company, a nonprofit is first established with the state. The early steps look familiar:

  • Choose and clear a compliant organization name (some states have specific naming rules for nonprofits).
  • File your articles of incorporation.
  • Appoint a board of directors – a few states require this before you file your articles.
  • Designate a registered agent in your state of formation.

Here’s the part that trips people up. Your articles of incorporation must do two things that ordinary formation documents don’t. First, they must explicitly state your exempt purpose – religious, educational, charitable, and so on. Second, they must include an asset-dissolution clause showing that, if the nonprofit ever shuts down, its remaining assets will go to another tax-exempt purpose rather than to individuals.

Putting this language only in your bylaws or operating agreement is not enough. The IRS wants it in the formation documents themselves. If it’s missing, you’ll have to amend your articles before you can even apply – which is why aligning your annual compliance requirements and governing documents from day one matters so much.

The Filing Path, Step by Step

Step 1: Get your EIN

Before applying for exemption, your organization needs an Employer Identification Number (EIN) for tax and banking purposes – required whether or not you have employees. You can handle this yourself or let Countsure manage obtaining an EIN alongside your formation paperwork so nothing stalls your IRS application.

Step 2: Choose between Form 1023 and Form 1023-EZ

Exemption is requested by filing IRS Form 1023, Application for Recognition of Exemption – or the shorter Form 1023-EZ if your organization is eligible. The streamlined version is faster and cheaper, but it’s only meant for smaller organizations, and certain entity types (such as churches, schools, and hospitals) generally can’t use it.

Factor Form 1023 Form 1023-EZ
Best for
Larger or more complex organizations
Smaller, straightforward nonprofits
Size limits
No asset or receipts cap
Generally ≤ $250,000 in assets and ≤ $50,000 annual gross receipts
Detail required
Extensive narrative, financials, and schedules
Short online eligibility checklist and attestation
Excluded entities
Open to all 501(c)(3) applicants
Churches, schools, hospitals, and certain others can’t use it

Step 3: Mind the 27-month window

Timing matters more than most founders realize. If you file Form 1023 within 27 months of forming your entity, your tax-exempt status can be applied retroactively to your date of incorporation. File after that window, and your exemption generally only reaches back to the date you submitted the application – leaving a potential gap of taxable months in between.

Step 4: Submit to the IRS and wait

Both Form 1023 and Form 1023-EZ are filed electronically. Nonprofits also submit financial statements and information such as the compensation of directors, officers, and key employees. After you file, you wait on the IRS to review and issue its determination – a step that can take anywhere from a few weeks to several months depending on the form and the complexity of your application.

After the IRS Says Yes: State and Local Exemption

Federal approval is a milestone, not the finish line. Once the IRS recognizes your exemption, you’ll usually need to secure tax-exempt status at the state and local level too – which can cover state corporate income tax, sales tax, and property tax. Requirements vary widely: in some states, your IRS determination letter is all you need, while others require a separate application.

And being tax-exempt doesn’t excuse you from everyday local rules. You still need the right permits, licenses, and building-code compliance to operate. Coordinating these alongside your US tax filing and exemptions keeps your organization clean across every jurisdiction it touches.

Staying Exempt: The Part Most Founders Underestimate

Earning 501(c)(3) status is one challenge; keeping it is another. To stay exempt, your organization must keep operating within the purposes described in its application and meet ongoing state and federal obligations. Key things to watch:

  • File your annual IRS return (Form 990, 990-EZ, or 990-N) every year. Miss it for three consecutive years and the IRS automatically revokes your exempt status – no warning, no appeal of the automatic revocation itself.
  • Keep up with state annual reports and maintain your registered agent.
    • Avoid private inurement – income or assets must not improperly benefit insiders such as directors or board members.
  • Stay out of political campaigns – 501(c)(3)s are prohibited from participating in or intervening in political campaigns for or against candidates.
  • File a management amendment with the state when your directors change, so your taxing status isn’t disrupted.

Parth Shah's expert view

The most expensive mistakes I see aren’t made on Form 1023 – they’re made months earlier, in the articles of incorporation. Founders download a generic nonprofit template, file it, and only discover at the application stage that it’s missing the exempt-purpose statement or the dissolution clause. Now they’re paying to amend state filings and losing weeks before they can even apply. My second piece of advice: don’t reach for Form 1023-EZ just because it’s shorter. If you realistically expect to grow past the size thresholds, or you’re an excluded entity type, the ‘easy’ form can cost you more in re-filing than doing it properly from the start. Build the foundation correctly, and the exemption tends to follow smoothly.

It depends on the form. Form 1023-EZ is often processed in a few weeks, while a full Form 1023 can take several months, especially if the IRS requests additional information. Timelines vary with IRS workload and how complete your application is.

No. Incorporating only creates your legal entity at the state level. To become tax-exempt, you must separately apply to the IRS for recognition under section 501(c)(3).

Possibly, if it’s small enough – generally $250,000 or less in assets and $50,000 or less in annual gross receipts – and isn’t an excluded entity type such as a church, school, or hospital. Check the IRS eligibility worksheet before filing.

If you file more than 27 months after formation, your exemption generally applies only from the date you submit the application rather than retroactively to your incorporation date.

Yes. A nonprofit can pay reasonable salaries to founders, officers, and employees for genuine work. What it can’t do is allow income or assets to improperly benefit insiders – that’s private inurement, and it can cost you your exempt status.

The main cost is the IRS user fee, which differs between Form 1023 and the streamlined Form 1023-EZ, on top of any state incorporation fees. Many founders also budget for professional help to prepare the formation documents and application correctly.

No – it’s not legally required, but it’s often recommended. The application is detailed and easy to get wrong, and errors in your formation documents or form selection can cause months of delay. Professional help reduces the risk of rejection or costly amendments.

Both are 501(c)(3) organizations, but a public charity draws financial support from a broad base – the general public, government, or other charities – while a private foundation is typically funded by a single source, such as a family or company. The IRS applies different rules and reporting requirements to each.

Yes. A nonprofit can earn more than it spends; the difference is called a surplus, not profit. The key restriction is that this surplus must be reinvested in the organization’s exempt purpose rather than distributed to owners, members, or insiders.

If the IRS revokes your status – for example, after three consecutive years of missed annual filings – your organization may owe federal income tax and donors generally can’t deduct their contributions. You can usually apply for reinstatement, but it requires a fresh filing and may involve back-filing missed returns.
