To register a nonprofit organization in the United States, you form a nonprofit corporation under your state’s law and then apply to the IRS for federal tax-exempt status under Section 501(c)(3). The state filing creates the legal entity; the federal application makes donations tax-deductible and exempts the organization from federal income tax. Most founders can complete both tracks within a few months. The single deadline that shapes everything else is the 27-month window after incorporation, because filing your exemption application inside that window lets the IRS backdate your exempt status to the day you formed.
Pick a Name and Appoint a Registered Agent
Your nonprofit’s name has to be distinguishable from every other entity already on file with your state’s business registry. Most states let you search their database online for free, and some offer a preliminary name availability check by phone or email before you file anything. Clearing a name with the state doesn’t protect you from trademark claims by another organization using the same name in commerce, so a federal trademark search is worth the extra step.
You also need a registered agent before you can file incorporation paperwork. That’s a person or company with a physical street address in the state of incorporation, whose job is to accept legal documents and government notices on the nonprofit’s behalf. Many founders serve as their own registered agent at first. Commercial registered agent services are available if you want a dedicated contact.
Line Up a Board of Directors
A majority of states require nonprofit corporations to have at least three directors, though a handful allow as few as one. Regardless of your state’s minimum, the IRS generally expects at least three board members on a 501(c)(3) application, and having fewer can invite extra scrutiny during review. You’ll need each director’s full legal name and mailing address before you can draft your incorporation documents.
Draft Articles of Incorporation and Bylaws
Articles of incorporation are the document you file with the state to create the nonprofit. For a 501(c)(3), the IRS requires your articles to include three things beyond what state law demands:
- A statement that the organization is formed exclusively for one or more exempt purposes, such as charitable, religious, educational, or scientific purposes.
- A restriction against any net earnings benefiting private individuals.
- A dissolution clause directing that if the organization shuts down, remaining assets go to another tax-exempt organization or to a government entity for a public purpose.
The IRS publishes suggested language for these clauses. Deviating from it is the single most common reason applications get delayed, so using the IRS template language verbatim can save weeks of back-and-forth with a revenue agent later.
Bylaws are your internal operating manual. They don’t get filed with the state, but the IRS requires a copy with your exemption application. Bylaws typically cover meetings, elections, quorum, and financial oversight. Most states provide sample bylaws through the secretary of state’s office.
File the Articles With Your State
Once your articles are drafted, you submit them to your state’s central business filing office, usually the secretary of state. Most states offer online portals that process applications within a few business days. Paper filing by mail is still an option everywhere, though processing can take several weeks.
Filing fees vary widely. Some states charge as little as $20, while others run several hundred dollars depending on the type of nonprofit and any expedited processing options. When the filing is approved, you receive a certificate of incorporation. Keep it safe; you’ll need it for nearly every step that follows.
Get an Employer Identification Number
An Employer Identification Number is the nonprofit’s tax ID. You need one before you can open a bank account, hire employees, or file for tax-exempt status. The fastest way to get an EIN is through the IRS online application, which issues the number immediately. You can also apply by fax or mail using Form SS-4, though those methods take longer.
Apply for 501(c)(3) Tax-Exempt Status
Federal tax-exempt recognition under Section 501(c)(3) is what allows donors to deduct their contributions and exempts the organization from federal income tax. Two forms are available, and eligibility turns on size.
Form 1023-EZ is available to organizations that project annual gross receipts of $50,000 or less for each of the next three years, have not exceeded $50,000 in any of the past three years, and have total assets valued at $250,000 or less. The user fee is $275.
Form 1023 is required for everyone else, including organizations with higher revenue, complex structures, or activities that don’t fit the streamlined form’s eligibility worksheet. It asks for a detailed narrative of your planned activities, three years of financial projections, and descriptions of how the nonprofit will achieve its exempt purposes. The user fee is $600.
Both forms are filed electronically through Pay.gov. You create an account, complete the form online, and upload a single PDF containing your articles of incorporation, bylaws, and any other supporting documents.
The application also asks whether you’ve adopted a conflict of interest policy. Adopting one is not actually required to receive exempt status, but the IRS strongly recommends it, and most serious nonprofits adopt one before applying.
Public Charity or Private Foundation
Every 501(c)(3) is presumed to be a private foundation unless it demonstrates it qualifies as a public charity. This matters because private foundations face stricter operating rules and excise taxes that public charities avoid. Your exemption application is where you make the case.
Public charities include churches, schools, hospitals, and organizations that receive a substantial portion of their funding from the general public or government grants. Most newly forming nonprofits that plan to fundraise from the public will qualify under one of the IRS’s public support tests. Private foundations are typically funded by a single family or small group and draw most of their support from investment income. If your nonprofit doesn’t fit a public charity category, private foundation rules apply by default.
Processing Times
The IRS reports that 80% of Form 1023-EZ applications receive a determination within 22 days for standard reviews. Applications that require additional scrutiny typically receive a decision within 120 days. The full Form 1023 takes considerably longer: 80% of those applications receive a determination within 191 days.
When the IRS approves your application, you receive a determination letter confirming your tax-exempt status and its effective date. This is the document donors, grantmakers, and state agencies will ask to see. You can download copies of determination letters issued since January 2014 through the IRS Tax Exempt Organization Search tool.
Meet the 27-Month Deadline
The timing of your federal application has real financial consequences. If you file Form 1023 or 1023-EZ within 27 months of forming your organization, the IRS can grant your exemption retroactively to the date of incorporation. Every donation received during the startup period then counts as tax-deductible.
File after the 27-month window closes and your exemption generally starts only from the date the IRS receives the application. Everything before that date is treated as taxable, and donors who gave during the gap lose their deduction. The IRS can extend the deadline for good cause, but that’s not a reliable safety net. Filing early is one of the cheapest forms of insurance a new nonprofit can buy.
Register to Solicit Donations in Each State
Federal tax-exempt status does not authorize you to solicit donations. Approximately 40 states have separate charitable solicitation laws that require nonprofits to register before asking residents for contributions. These registrations are typically managed by a state’s attorney general or consumer protection office and usually require a copy of your IRS determination letter and financial statements.
Most states require annual renewal to maintain the legal right to fundraise. Failure to register or renew can result in fines or loss of solicitation privileges. If your nonprofit plans to fundraise across state lines or online, you may need to register in every state where you solicit.
File Annual Returns to Keep Your Status
Once you have tax-exempt status, federal law requires an annual information return with the IRS. The form depends on your size:
- Form 990-N (e-Postcard), for organizations with annual gross receipts normally $50,000 or less. This is a brief electronic notice, not a full return.
- Form 990-EZ, for organizations with gross receipts under $200,000 and total assets under $500,000.
- Form 990, for organizations exceeding either of those thresholds.
The consequences of skipping this filing are severe. If your organization fails to file its required return or notice for three consecutive years, the IRS automatically revokes your tax-exempt status. There is no appeal process for a proper automatic revocation. Once revoked, the organization must pay income taxes, donors lose their deduction, and you have to reapply from scratch. This is the most common way small nonprofits lose their status, and it’s entirely preventable.
Wrap Up the Practical Setup
With your determination letter in hand, open a dedicated bank account. Financial institutions typically require your articles of incorporation, bylaws, EIN confirmation, a board resolution authorizing the account, and a copy of your determination letter. Mixing organizational funds with personal accounts is a governance red flag that can jeopardize your exempt status.
Most states offer their own sales tax exemption for qualifying nonprofits, but it isn’t automatic. You generally apply separately with your state’s revenue or taxation department, providing your IRS determination letter and financial statements. The application is usually free, though process and eligibility vary by state.
One immediate federal benefit of 501(c)(3) status is exemption from the Federal Unemployment Tax Act. Wages paid to employees of a 501(c)(3) are not subject to FUTA tax, saving the organization 6% on the first $7,000 of each employee’s annual wages. State unemployment tax obligations are separate and vary by jurisdiction.
